United States Patent 3,001,310 MACHINE FOR APPLYINGTRANSFERS Kenneth H. Brownlee, Skokie, Ill, assignor to TheMeyercord Co., Chicago, 113., a corporation of Illinois Continuation of application Ser. No. 572,937, Mar, '21,

1956. This application Oct. 19, 1959, Ser. No. 847,860 28 Claims. (Cl. 156-461) This application is a continuation of my copending application Serial No. 572,937, filed March 21, 1956, now abandoned.

This invention relates to a machine for applying decalcomania transfers and more particularly to a machine adapted to apply a plurality of such transfers simultaneously to a plurality of articles. The present invention constitutes an improvement over the transfer applying machines shown in my earlier Patents Nos. 2,493,522 and 2,493,523 and has particular utilization and advan tage in the application of revenue stamps to packages, such as cigarette packages, prior to sale to the general public. It is to be understood, however, that the machine of the present invention has application to the marking of a wide variety of other articles with a wide variety of other types of decalcomania transfers.

It has been found that the application of water applied transfers in the form of revenue stamps, labels or stickers to packages to be marked which requires moistening the transfers so as to release them from the carrier paper sheet and then adhering them to a plurality of packages by the water method by addition of adhesive or by solvent activation ofadhesive, is so time consuming and expensive as to render such transfers unsuited for revenue tax stamp purposes. This was particularly true where many thousands of individual cigarette packages demand the application of tax stamps thereto in a relatively short period of time.

On the other hand tax stamp transfers which are applied by heat lend themselves to more rapid application to the cigarette packages and eliminate the use of water, solvents, and many manual operations. However, the handling of such heat-applied transfers has presented some difliculties and disadvantages resulting from machine operation, such as imperfect release of the transfers from the carrier sheet, imperfect adherence to the package or article being marked, relatively slow operation of the machine thus reducing the required high rate of marking, malfunctioning of the machine, and the necessity of manual operations of the machine in carrying out the transfer release and applying process.

It is, therefore, one of the principal objects of the present invention to provide an improved machine adapted to apply decalcomania transfers to articles.

Another object of the invention is to provide a machine adapted to apply decalcomania transfers simultaneously to a plurality of articles which is automatic in operation through its cycles and requires no manual operation on the part of an attendant except the feeding thereto of articles to be marked if any auxiliary automatic feeding mechanism forming no part of the present invention is not provided.

A further object of the invention is to provide a machine of the foregoing character wherein the transfer applying mechanism is automatically set in operation by the insertion in the machine of an article to be marked and which cycle of operation is automatically terminated upon removal of the article from the machine.

Still another obiect of the invention is to provide a machine of the foregoing character wherein operation of the transfer applying mechanism is automatically initiated by the insertion into the machine of successive groups of articles to be marked simultaneously.

A still further object of the invention is to provide a transfer applying machine having a mechanism for automatically feeding a carrier sheet bearing the transfers through a marking zone and a mechanism comprising a heated platen adapted to be automatically moved to and out of cont-act with said carrier sheet, said mechanisms being operable automatically in timed relation.

Another further object of the invention is to provide a transfer applying machine having a mechanism for automatically feeding a transfer carrying sheet through a marking zone and a mechanism comprising a heated platen having a plurality of transfer engaging sides and adapted to be automatically moved to and from transfer applying position in contact with said carrying sheet, said mechanisms being synchronized in their operation and said sheet feeding mechanism being automatically operable once during a predetermined plurality of cycles of machine operation and said platen being automatically operable and rotatable every cycle of machine operation to bring said platen sides successively into operable position for applying a plurality of transfers from different groups of transfers on said sheet to different groups of articles as they are successively passed through the machine.

The declacomania transfer applying machine shown in the drawings constitutes a preferred embodiment of the present invention and, referring to FIGS. 1, 2, 4 and 5, comprises left and right end plates or castings 20 and 21, respectively, secured together in spaced relation by front and rear spacer rods 22 and 23 at the lower portions of said end plates and by cross shafts 24 and 26. Access to the interior of the machine is afforded through a removable curved cover plate 27 supported by the end plates 20 and 21.

Extending longitudinally through the machine and supported in openings in the end plates 20 and 21 is an openended and open-topped chute 29 which is of proper dimensions and length to accommodate cartons containing a plurality of cigarette packages to which the decalcomania transfers are to be applied. As shown in FIG. 12, an auxiliary channel-shaped plate 29a may be inserted Within the chute 29 in order to make the chute 29 shallower and to accommodate packages of cigarettes of the regular or shorter size. When cigarette packages of the longer size are to be marked, the plate 29a may be removed. To provide for a fine adjustment, the chute 29 is vertically movable by means of spaced cam adjustment disks 30 (FIGS. 2, 4 and rotatably mounted on stub shafts 31 projecting inwardly from the end plates 20 and 21. The cam disks 36 engage bearing pads 32 secured to the under surface of the chute 29 and rotation of the disks will effect raising or lowering the chute as desired. The disks 30 may be locked in adjusted position by lock screws 25 having finger pieces 25a secured thereto.

As shown in FIGS. 1, 2, 12, 13 and 14, a housing 33 is secured by bolts 34 to the outer side of the right end plate 21 and supports rotatably mounted rubber ejection rollers 36 which serve to grip and eject the cartons after the packages 37 therein have each been marked simultaneously with a transfer. Each roller 36 is secured through its core 39 which projects downwardly therefrom to the upper portions of spaced vertical shafts 38 which are journaled in bosses 33a and web portions 33b of the housing 33. The upper ends of the shafts 38 are journaled in recesses 40in the upper portion of the housing 33. On the lower end of shafts 38 are bevel gears 41, which are inconstant mesh with bevel gears 42 secured on a horizontal rotatable cross shaft 43 journaled in bearing openings 44 in the lower ends 33c of the housing 33. Shield plates 33d are formed on the outer face of the housing 33 and extend in front of the rollers 36 to partially enclose the same.

A pulley 46 is secured on shaft 43 and a belt 47 drivingly connects the pulley 46 to a pulley 48 of reduced size on the end of the armature shaft 49 of an electric motor 50. A speed reducer 51 driven from the armature shaft 49 has an output shaft 52 in alignment with a cam or driving shaft 53 which extends longitudinally through the machine and is journaled in bearings in the end plates '20 and 21. The right end of the cam shaft 53 projects beyond the outer face of the end plate 21 and is adapted to be clutched to the output shaft 52 by an electric clutch 54 of the well known type, the details of which need not be shown for the purposes of this invention. The clutch 54 comprises clutch members 54a and 54b keyed to the shafts 52 and 53, respectively. The clutch 54 is operated to engage and disengage the clutch members 54a and 54b through a system of relays and switches to be described presently. On the left end of the cam shaft .53 which projects beyond the outer face of the left end from from coasting beyond the desired cycle of operation, thereby affording positive and precise operation.

As shown more particularly in FIGS. 2, 4 and 5, the cam shaft 53 has keyed to it adjacent the left and right inner faces of the end plates 20 and 21, box cams 57 of similar construction having cam tracks 58 formed in the vertical side faces thereof. Cam followers or rollers 59 are rotatably supported on pivot pins 60 carried by right and left cam lever arms 61 intermediate the ends thereof and these rollers project into the cam tracks 58 of the box cams 57 so that rotation of the box earns 57 will effect a pivotal raising or lowering movement of the cam lever arms 61. The forward ends of the lever arms 61 are pivoted on the cross shaft 24 and their rearward ends arepivotally secured to the lower forked ends of vertical connecting rods 62 which extend upwardly and have their upper ends pivotally connected to the left: and right ends, respectively, of a movable cross rod 63" and extending therebetween.

A pair of spaced rocker plates 64 are rockably mounted adjacent the inner faces of the end plates 20 and 21, respectively, on a fixed cross shaft 66 supported by and extending between the end plates 20 and 21, and they are connected at their rearward ends by the cross rod 63 and at their forward portions by a cross rod 67. By the foregoing construction, rocking movement of the rocker plates 64 to and from transfer applying position will be effected by rotation of the cam shaft 53 through the box earns 57, rollers 59, lever arms 61, connecting rods 62 and cross shaft 63.

A heated iron or platen 68 by which the transfers are applied to the cigarette packages, as shown more particularly in FIGS. 1, 2 and 4 to 6, inclusive, is rotatably carried by and between the rocker plates 64 and comprises an electric heating element or coil 69 disposed within a tube 70 press fitted within the main body portion of the platen. The platen is provided with three groups or sets of radially projecting heat conducting projections or units 71, 72 and 73 having flat heated surfaces, these groups of units being disposed at intervals. The fiat heated surfaces of the projections 71, 72 and 73 are adapted to be brought into successive contact with the decalcomania transfers as the platen 68 is rotated relative to the rocker plates 64 on each cycle of machine operation by a mechanism which will now be described.

Referring to FIGS. 6 and 7 of the drawings, the platen 68 has left and right shaft ends 74 and 76 fixed to the ends of the tube 70 and extending through the rocker plates 64 and being rotatable with respect thereto. The outer left end of the platen shaft 74 has a spur gear 77 loosely mounted thereon and adapted to mesh with the internal teeth of a stationary gear segment 78 secured to the inner face of the end plate 20 by screws 79 and spaced therefrom by spacing collars 80. Mounted on the shaft 74 between the spur gear 77 and the left rocker plate 64 is a pawl and ratchet mechanism comprising a ratchet 81 secured to the shaft 74 for rotation therewith, a pawl 82 engageable with the ratchet and a pawl crank 83 loosely mounted on the shaft 74 and having a pin 84 upon which the pawl 82 is pivotally mounted. The pawl crank 83 and the gear 77 are secured together for unitary rotation by a plurality of studs 75. The pawl 82 is pressed against the ratchet 81 by a leaf spring 86 carried by the pawl crank 83. I The ratchet 81 is provided with three notches 87 of equal depth and equally spaced about its outer periphery at 120 intervals and the pawl 82 is with the paper web 89 or is in non-applying position, the

spur gear will be rotated clockwise approximately 120 by its engagement with the stationary gear segment 78.

Rotation of the gear 77 will rotate pawl crank 83 alike amount also in a clockwise direction so that the pawl 82 will engage in a notch 87 and force rotation of the ratchet 81 and the platen shaft 74. Hence, the platen 68 will be rotated clockwise also to an extent of 120 so as to bring another of the three groups of heated platen projections into operable downwardly projecting position for engagement with the paper web 89. As the rocker plates 64 are returned to their lowered position of FIG. 4 so that the platen 68 will be in transfer applying position, the platen 68 will not be rotated inasmuch as the pawl crank 83 and gear 77 will be rotated in a counterclockwise direction and the pawl 82 will ride over the notches 87 of the ratchet.

As shown in FIGS. 6 and 8, a brake mechanism for holding the platen 68 in the position to which it has been moved upon rocking of the plates 64, is disposed at the right side of the platen and comprises a brake shoe 76a pivoted on a pin 76b carried by the right rocker plate 64. The brake shoe 76a is pressed by a spring 76c on the rocker plate 64 into frictional engagement with a drum 76d secured on the right platen shaft 76. Thus, when the platen 68 is moved downwardly into engagement with the paper web 89, it is held by the brake mechanism with the selected group of projections in proper position for flat over-all engagement with the surface of the paper web 89. 1

As shown in FIGS. 4, 5 and 15, the decalcomania transfers 88 are carried on a sheet of waxed paper 89 in the form of a supply roll 90, and, referring to FIGS. 1 and 2, the supply roll 90 may be supported on left and right cones 91 fixed on the ends of stub shafts 92 extending inwardly from the end plates 20 and 21. The right cone 91 and shaft 92 may be adjusted longitudinally of the machine by an adjusting screw 93 and a lock nut 93a. The paper web 89 with the transfers on the under surface thereof extends from the paper roll 90 forwardly of the machine over a roller 94, under the shaft 66, over another roller 96 and thence across the open top of the chute 29 and beneath the heated platen 68 to guide rollers 97 and 98.

The paper guide rollers 97 and 98 are supported on rods 99 and 100, respectively, which along with a tie rod 101 extend between and are carried by left and right pivoted rod holders 102. The rod 100 is supported at its respective ends in the end plates 20 and 21. The rod holders are urged in a clockwise direction, as viewed in FIGS. 4 and 5, by springs 103 anchored on end plates 20 and 21. As shown in FIGS. 4, a bumper 95 carried by the rocker plates 64 engages the upper inner corners of the rod holders 102 when the rocker plates lower the platen to transfer applying position and rocks them in a counterclockwise direction so as to lower the roller 97 and provide the necessary slack in the paper web 89 which is required when the platen 68 moves the paper web 89 down into the chute against the upper surfaces of the packages. In FIG. 5, the bumper 95 is shown raised out of engagement with the rod holders 102 so that the roller 97 is in raised position with the paper web 89 also in raised position and extending substantially horizontally over the top of the chute 29 so as not to interfere with the passage of articles along the chute 29.

The paper web 89 passes between the rollers 97 and 98 and then up over the tie rod 67 and rearwardly around an idler roller 2 journaled in a bearing block 1020 in inclined slots 10% in the end plates and 21. The paper web then passes into engagement with a driving roller or sprocket 103, as shown in detail in FIGS. 9, 10 and 11, secured on a rotatable shaft 105 and having a plurality of lugs or teeth 104 adapted to be received within marginal perforations 106 in the paper web 89. The sprocket roller 103 is intermittently driven by a mechanism presently to be described and pulls the paper web 89 off the roll 90 and over the chute 29 as above described. The paper web passes from the sprocket roller 103 around a pressure roller 107 and thence upwardly out of the machine through an elongated slot 108 in the cover 27. As shown more particularly in FIGS. 9 and 11, the left and right ends of the pressure roller 107 are journaled in bearings 109 which. are slidable in inclined slots 110 in the end plates 20 and 21. Brackets 111 are secured to the cover 27 and have adjusting screws 112 for regulating the thrust force, of springs 113 compressed between the screws and the bearings 109. Adjustment of the screws 112 will adjust the pressure loading of the paper feeding mechanism.

As shown in FIGS. 4 and 5, an elongated stripper plate 114 extends longitudinally of the machine and engages the upper surface of the paper web in front of the pressure roller 107 so as to cause the paper web to become disengaged from the sprocket teeth 104 and to pass around the pressure roller 107 and out through the cover slot 108. The stripper plate 114 is riveted at each of its ends to strap members 116 mounted on the spacer rod 26.

Adjacent the right end of the sprocket roller 103 is a spur gear 117 in mesh with a spur gear 118 on the pressure roller shaft 107a so that the pressure roller 107 is driven by the sprocket shaft 105. Pinned to the shaft 105 adjacent the spur gear 117 is a brake drum 119 which is engaged on its outer periphery by a brake shoe 120 pivotally mounted on a pin 121 projecting inwardly from the right end plate 21. -A pressure spring 122 held in a stud 123 on the end plate 21 engages the brake shoe 120 and forces the shoe to bear against the drum with the desired pressure, thus holding the paper drive roller 103 in its advanced position against reverse rotation and thus holding the paper web with the desired degree of tautness.

Referring more particularly to the paper roller drive mechanism shown in FIGS. 7, 9 and 10 of the drawings, a spur gear 124 is loosely mounted on the roller shaft 10 as a floating member for rotation relative thereto and is spaced from the sprocket roller 10 3 by a collar 126. The gear 124 is in mesh with an external gear segment 12t7 mounted on the upper edge of the left rocker plate 64 so that rocking movement of the plate 64 will effect rotation of the spur gear 124. A pair of cranks 128 and 129 are loosely mounted on the shaft 105 and are connected together by a connecting pin for unitary operation. The crank 129 is connected to the spur gear by a plurality of pins 130 whereby rotation of the spur gear 124 will rock the cranks 128 and 129. Between the cranks 128 and 129 on the shaft 105 are ratchets 13 1 and 132 which are engaged by a pawl 133 carried by the connecting pin 125 and urged into engagement with the ratchets 131 and 1:32 by spaced leaf springs 135. The ratchet 132 is loosely mounted on the shaft 105 whereas ratchet 131 is the drive ratchet and is fixed to the shaft whereby rotation of the ratchet 16 1 will effect rotation of the shaft 105 and hence rotation of sprocket roller 103.

The ratchet 1 32 is of larger diameter than the ratchet 13 1 (FIG; 10') and each ratchet is provided on its outer periphery with three notches spaced approximately 120 apart. All of the notches 1811a of the ratchet 131 are of equal depth. Two of the notches 13211 of the ratchet 1'32 are more shallow than the third notch 13212, which is deeper and of a depth equal to the notches 131m of the ratchet 131. By this relationship of notch depth, movement of the pawl 133 will engage in the shallow notches 132a and rotate the ratchet 1 32 upon each rocking movement of the rocker plate 64 and rotation of the ratchet 131 will not be effected until the pawl engages in the deep notch 132b of the group. As seen in FIG. 10, as the pawl 133 falls into the deep notch 1321), it will also project into one of the three correspondingly deep notches 131 of the drive ratchet 131 so that both ratchets will be rotated, the rotation of the drive ratchet 131 causing rotation of the shaft 105 and hence a feeding rotation of the paper drive roller 103. By this pawl and ratchet construction, the paper drive roller 103 is rotated only once every three rocking movements of the rocker plate 64. This is in contrast to the heated platen operating means which functions upon each rocking movement of the rocker plate 64.

As shown in FIGS. 1, 2, 4, 5, 1-3 and 14, a carton stop is provided in the chute 29 near the inner side of the right end plate 21. This stop comprises a pair of hinge plates 136 and 137 joined together by a hinge pin 138. The hinge plate 136 is stationary and is secured to the outer side of the vertical wall of the chute 29 by screws 139. The other hinge plate 137 constitutes the stop member and is adapted to be projected through an opening 1'40 in the wall of the chute into carton or article blocking position and, as shown in FIGS. 13 and 14, is held in the path of the cartons by a releasable stop lever 141, the free left end of which engages a pad 142 on the adjacent movable hinge plate 137 and the right end of which is pinned to the upper end of a rock shaft 143. This shaft 143 extends downwardly in the machine through a bearing block 144 secured to the end plate 21. r

A notched latch 146 is pivoted on a pin 147 on the upper side of the bearing block 144 and its notch 148 is adapted to engage a lug 149 on the end of the stop lever 1 41 as the lever 141 is pivoted by rotation of shaft 143. The latch 146 is urged in a counterclockwise direction, as viewed in FIGS. 13 and 14, by a spring 150 tensioned between a pin 151 on the latch 146 and a pin 152 on the bearing block 144. The rearward end of the latch 146 projects into the chute through the elongated slot 140a in the chute wall which extends to the right from the larger opening 140. A pair of spaced tongues 153 project into the opening 140 and serve as a stop against which the side edge of the hinge plate 137 strikes so as to be limited in its pivotal movement. 7

The lower end of the rock shaft 143 has secured thereto a cam follower comprising a roller 154 carried by a movable arm 156 which is clamped to the shaft 143. The roller 154 engages the outer periphery of the right box cam 57 and is adapted to be actuated by a cam lobe 157 secured to the box cam by a bolt 158 extending through an arcuate slot 159 of the lobe. This bolt and slot connection permits the lobe 157 to be mounted in the box cam 57 in the desired position for actuation of the cam follower at the proper point of time in the cycle of machine operation. In FIGS. 4 and 5, the cam roller 154 is shown in solid lines in engagement with the outer periphery of the box cam 57 and out of engagement with the lobe 157. In this position, the cam arm 156 and the shaft 143 are not turned and the carton stop mechanism is in the stop or blocking position shown in FIG. 14 with the hinge plate 137 held in projected position in the chute 29. In FIG. 5, the cam lobe 157, as shown by the broken lines, has been rotated into engagement with the cam roller 154, also shown in broken lines, and has forced the roller to the position shown with the result that the cam follower arm 156 has been rotated to cause rotation of the shaft 143.

Rotation of the shaft 143 by the box cam lobe 157 will be in a counterclockwise direction as viewed in FIGS. 13 and 14 so as to rotate the stop arm 141 inwardly out of holding or blocking engagement against the hinge plate 137 and to permit the hinge plate 137 to be forced inwardly by a carton or article into a position substantially parallel with the chute well. When this occurs, the cigarette carton may be pushed beyond the stop and into engagement with the projecting end of the latch 146 which also will be turned on its pivot and forced out of the way by the carton. Movement of the carton to the right is continued until the front end thereof is engaged by the rotating ejection rollers 36 which thereupon grip the sides of the carton and eject the carton at a rate more rapid than the rate of insertion of the following carton next to be marked for a purpose to be explained more fully hereinafter. By the time the rear end of the carton containing the packages to which transfers have been adhered by the heated platen 68 has cleared the stop 137 and the latch 146, the lobe 157 has also passed out of engagement with the cam follower 154 thus permitting the stop arm 141 to be rotated clockwise so as to force the hinge plate 137 into the chute to its carton stopping position for engagement with the next succeeding carton.

Referring to FIGS. 1, 2, 4, 5, 13 and 14 of the drawings, a microswitch designated generally by the numeral 169 is secured on the side wall of the chute 29 immediately preceding the carton stop 137. The microswitch which may be of the usual form comprises a switch actuating plunger 161 extending at right angles to the chute wall and an arm 162 pivoted at 163 to the chute and extending in the direction of movement of the cartons through the chute. An arcuate plate 164 is secured on the outer free end of the pivoted arm 162 and is adapted to project into the chute into the path of movement of the cartons. The free end of the pivoted arm 162 engages the outer end of the switch actuating plunger 161 so that when a carton is pushed into and along the chute, the side face of its leading portion will engage the curved plate 164 and depress the plunger 161. Actuation of the microswitch will through the system of relays presently to be described, de-energize and release the brake 56 and energize and actuate the electricclutch 54 to engage the same and drive the cam shaft 53.

A second microswitch that is cam operated is shown in FIGS. 2 and 3 of the drawings. This microswitch desig nated generally by the numeral 166 is of the usual type of two way switch and is supported on the left end portion of the front lower tie rod 22. The switch comprises an actuating plunger 167 projecting into the path of movement of and engageable with a cam lobe 168 carried by the left box cam 57 for rotation therewith. This lobe is positioned on the left box cam 57 so as to actuate the microswitch plunger 167 to one position just before the heated platen 68 and rocker plates 64 reach their fully raised position and to release the switch to its other position after the down stroke of the platen has commenced. Actuation of the microswitch 166 will effect engagement of the brake 56 which will lock the shaft 53 against further rotation and hold the platen in its raised position until the chute switch 161) is released and again depressed by another carton to initiate the cycle of operation.

The heating element 69 of the platen 68 and the electric motor 511 are electrically connected to a source of electric current through circuits which may be separate from the clutch and brake actuating circuit and each is provided with separate manual switches (not shown) so that the motor and heating element may be operated as desired without being aifected by automatic operation of the microswitches 160 and 166.

In FIG. 16, the electrical circuit for controlling the clutch 54 and the brake 56 is shown diagrammatically. When the main switch 170 is closed, the circuit is closed through the brake 56 through the normally closed switch 171a controlled by the relay 171, thus applying the brake. However, the switch 171!) which is controlled by the relay 171 and which is in the line to the clutch 54 is normally disengaged. Also the relay 172 is energized when the main switch 170 is closed thus closing the switches 172a and 17212.

When a carton closes the chute microswitch 160 by engagement therewith, relay 171 is energized and opens switch 171a in the line to the brake so as to release the same and also closes the switch 171]) in the line to the clutch to engage the same. Energization of the relay 171 also closes the switch 1710 and opens the normally closed switch 171d. The relay 172 remains energized.

on its cycle of operation as above described.

scorers With the circuits thus established, the machine proceeds During the movement of the platen 68in its down stroke to transfer applying position, the cam switch 166 is released by the cam lobe 168 on the left box cam 67 and this switch then transfers to the contact 166a from 1661) with the result that the relay 172 is deenergized and the relay switches 172a and 17% are opened. However, the relay 171 is held in energized condition through the cam switch 166 in its right position through contact 166a so that the brake 56 remains off and the clutch 54 remains engaged.

As platen breaks off contact from the paper web 89 when it starts its movement to raised position after having applied transfers to the articles in the carton, the carton is moved ahead in the chute 29 by the next succeeding carton and is rapidly ejected from the machine by the rollers 36. A space is created between the front end of the entering carton and the rear end of the departing carton due to the rapid rate of ejection and the slower rate of feed and hence pressure is relieved from the arm 162 and the chute switch 160 is free to restore itself to its initial position. This restoration of the switch 160 does not, however, affect the brake or the clutch mechanism since they continue to be held in their released and engaged positions, respectively, through the other relay switches. However, shortly before the rocker arms 64 and the platen 68 reach their fully raised position, the cam switch 166 is again actuated by the cam lobe 168 on the left box cam 57 so as to transfer the cam switch 166 back to the left to its 16Gb contact position. This causes the relay 171 to become deenergized so as to open the clutch relay switch 171b and disengage the clutch 54 and simultaneously to close the brake relay switch 171a and apply the brake 56. The relay 172 likewise is energized.

The next carton then engages and operates the chute switch 160 which, as described above, releases the brake 56, engages the clutch 54, and the transfer applying cycle of the machine is again repeated.

It is to be noted that the electrical circuit shown in FIG. 16 and described is of such character that the chute switch 160 must be released and again closed to initiate successive cycles. Since all revenue stamps used must be paid and accounted for, this requirement serves as a safety factor and prevents the machine from repeating or passing on to its next cycle and from applying a second group of pairs of transfers on the same packages that have already been stamped. Thus, as long as a marked carton remains in the chute 29, it holds the chute switch 160 in engaged position and recycling or a repeat marking is prevented. The cycle for the next marking operation can only be initiated by removing the stamped carton, which thereby creates a space between the cartons and permits the switch 160 to be released, and then by again depressing the switch 160 by the next succeeding carton to be marked.

In operation of the machine, the leader portion of the waxed paper web 89 bearing the transfers 88 on the under surface thereof is first pulled off the supply roll 90 and fed through the various rollers and secured around the drive roll 103 as above described, the first two rows of decalcomania transfers being disposed over the chute 29 and the heated platen 68 being in raised position. With the platen heated to the desired degree of temperature by energization of its element 69 and with the motor 50 in operation, the machine is ready to receive and to apply a plurality of transfers to a plurality of articles such as cigarette packages 37 in cartons. At this point in the cycle, the brake 56 is applied and is holding the cam shaft 53 against rotation and the clutch 54 is disengaged so that no drive is being transmitted to the machine from the operating motor 50.

A carton containing the usual ten packages 37 of cigarettes in upstanding position and which has been opened to expose the upper surfaces of the packages is then pushed into the chute 29 and into engagement with the hinged stop 137 which at this point of the cycle is held in projected blocking position in the chute 29 by the arm 141 and positions the packages in proper alignment under the platen 68. However, just immediately prior to engagement of the front edge of the carton with the stop 137, the carton will engage the pivoted switch arm 162 and depress the plunger 161 of the chute microswitch 160 which through the relays above described will engage the clutch 54 and disengage the brake 56. This will release cam shaft 53 for rotation and it will be rotated through the engaged clutch 54 to operate the machine through its transfer applying cycle.

Rotation of the shaft 53 will rotate the left and right box cams 57 and cause the cam rollers 59 on the pivoted arms 61 to roll up to the high points of the cams which results in rocking the rocker plates 64 clockwise as viewed in FIGS. 4 and 5 and lowering the heated platen 68 downwardly until one group of heated projections 73 engage the upper surface of the Web 89. Just before the heated platen 68 reaches its fully depressed position, the bumper engages the rod holders 102 and pivots them downwardly in a counterclockwise direction so as to provide sufficient slack in the paper web 89 to reach the upper surfaces of the packages within the open carton as pressure is applied thereagainst by the heated projections 73. During this engagement, every third pair of transfers 88 in the two rows over the chute 29 are released from the paper web and are adhered securely by heat to the upper surfaces of the packages 37.

Upon continued revolution of the cam shaft 53, the rollers 59 drop down into the lower point of the cam so as to lower the cam arms 61 and the connecting rods 62 and hence rock the plates 64 in a counterclockwise direction and raise the heated platen 68 out of engagement with the paper web 89. The cam lobe 157 is positioned on the right box cam 57 so that it engages the cam roller 154 immediately after the heated platen has broken off contact with the paper web as it is being raised. At this point in the cycle, the cam lobe 157 moves the cam roller 154 to its broken line position of FIG. 5 so as to rotate the stop holding arm :141 and permit the stop 137 to be pushed out of the way as another carton of cigarettes is inserted in the chute 29 to push the carton of marked packages into the space be tween the rollers 36.

The rollers 36 rotate at a very rapid rate and faster than the rate of feed of the unmarked cartons into the machine with the result that the marked carton will be rapidly ejected to open up a space between the marked and unmarked cartons and permit the stop member to be projected back into the chute 29 and held in carton blocking position by the arm 141. The cam lobe 157 remains in engagement with the stop actuating roller 154 only during a short duration of the cycle and that en gagement is broken off in sufficient time to permit the stop 137 to be reestablished in blocking position as soon as the space is opened up when the marked carton is rapidly ejected.

As explained above, as the left rocker arm 64 is rocked toward its raised position of FIG. 5, the gear 77 is caused to rotate by the fixed gear segment 1-27, and through the pawl and ratchet mechanism associated therewith the platen 68 is caused to rotate 121i" and to bring the next group of heated projections 72 into the down position for engagement with the next spaced pairs of transfers when the machine is thereafter operated through its cycle.

The box cams 57 continue to rotate and the rocker arms 64 and the heated platen 68 continue to move to raised position until top dead center is reached. Immediately before the fully raised position is reached, the cam lobe 168 on the left box cam 67 engages and operates the microswitch 166 so as to apply the brake 56 and disengage the clutch 54, and thereafter until the chute raised and the platen is again rotated to bring the third set of heated projections 71 into the down position for engagement with the third and only remaining groups of pairs of transfers 88 in the two rows over the chute 29. The cycle is again repeated as a third carton is moved into position and the second carton removed, and

the packages in the third carton are likewise marked with transfers. Removal of the third groups of pairs of transfers will complete the removal of all transfers in the two rows on the paper web over the chute Z9 and hence when the rocker arms 64 and the platen 68 are raised upon completion of the marking of the third carton, not only will the platen 68 be rotated another 120 to bring the set of heated projections 73 into operable position but the paper drive roller 103 will likewise be rotated so as to pull another section of the paper web 89 off the supply roll 90 and bring two more rows of transfers 88 into proper registry over the top of the chute 29 for application to three more succeeding cartons of cigarette packages.

Although there has been shown in the drawings and described above a preferred embodiment of the present invention, it is to be understood that changes and modifications may be resorted to without departing from the spirit and scope of the appended claims.
