United States Patent 3,129,800 STRI? EMBOSSENG IMPLEMENT Benedict E. Bogeaus, 10350 Sunset Blvd., Los Angeles, Calif. Filed Mar. 18, 1963, Ser. No. 265,725 14 Claims. (Cl. 197--6.7)

This invention relates generally to the impressing of characters or other indicia onto strips of embossable material, and more particularly to an improved hand held and hand operated printer for making strip labels or tags such as from a length of contrast color embossable plastic dispensed from a magazine carried by the device.

With the development in recent years of thin sheet plastics which, when crazed by an embossing process, assume a sharply contrasting color or reflectivity in the crazed area compared to the sheet background color, a number of hand held hand operated tools for embossing and dispensing strip labels have been developed. In general, the better of these tools util zes two hinge-pivoted handle members, one of which supports a dispensing magazine, a ratchet feed mechanism, and a rotatable, indexed embossing die means. The handle members are hingepivoted at their front ends, and an anvil extension spaced rearwardly therefrom on one handle member engages the embossing die means, supported on the other, when the operator urges the two handle members toward each other. The action is that of a lever of the second class and requires a relatively great magnitude of tangential displacement at the handles rear ends in order to move the anvil extension a given distance toward the die means.

The hinge action is also used to operate the ratchet feed mechanism which is disposed rearwardly of the anvil extension. The tape magazine is carried at the extreme rear end of one of the handle members; and its output of tape is fed over the distance of a handle length, through the feed mechanism, past the die means, past a viewing window, and out of the front end of the tool.

Typically such prior art tape embossing tools suffer the disadvantages of being relatively large and heavy and not optimurnly convenient to handle and operate. In addition they are mechanically complicated with many interrelated moving parts causing them to be relatively expensive to manufacture, and, because of wear and fragility of the moving parts, relatively difiicult and costly to maintain. Further, due to the placement of the tape magazine in the extreme rear end portion of one of the handles, an extended threading process is required to bring the tape end from the magazine to the feed mechanism; and when the feed is reversed, buckling of the tape in the extended region results. Furthermore, in this connection, it is, as a practical matter, useful but not possible or practical in tape embossers heretofore available to be able to advance the tape from between the die members for observation of the last embossed character or characters and then to reverse the tape and continue printing without irregular or faulty spacing of the characters.

A final disadvantage to be noted in connection with such prior art devices is that because of the large magnitude of relative motion between the handle members required for actuation of the feed ratchet and die anvil, and in order to minimize the overall dimensions of the tool, the handle members approach each other very closely during the embossing step. The close approach thusly required causes annoyance and danger to the operator because of pinching of the tissue of the operators hand.

It is therefore an object of the present invention to provide a hand operated, portable, strip embossing device which does not suifer these and other disadvantages of the prior art.

It is another object to provide such an implement which is relatively simple in its construction and mechanically reliable.

It is another object to provide such an implement which is highly compact and light in weight.

It is another object to provide such an implement which holds tape dispensing magazines integrally in its body portion.

It is another object to provide such an implement which does not require manual threading of the embossing tape over an extended distance through or along a handle member.

It is another object to provide such an implement with which the operator may arbitrarily advance and reverse the tape and restart without irregular or faulty spacing of the imprinted characters and which rewinds the tape into the magazine during the reversing step.

It is another object to provide such an implement which achieves tape advance and embossing with relatively slight motion of a single handle member.

It is another object to provide such an implement which cannot pinch the hand of the operator.

It is another object to provide such an implement in which the embossing force applied by the die actuating anvil is relatively independent of the force applied to the movable handle so that uniform embossing is accomplished whether the operator is a small child or a large man.

Briefly, in accordance with the structural features of an example of the present invention, these and other objects are achieved in an embossing implement having a body portion which contains a tape magazine and a ratchet feed mechanism and which has a rigid handle extension. A movable handle is carried by the body and is pivoted about the axis of the feed ratchet and is disposed in a manner to form, with the rigid handle extension, a cooperating pair of handles to be gripped by an operators hand. The handle extends forwardly of its pivot axis in the manner of a lever of the first class and its forward extension carries an upwardly projecting, small punch and anvil member adapted to move upwardly to engage and actuate an embossing die when the handle is squeezed downwardly toward the right handle extension.

An action multiplier-bar is provided which is pivotally carried at one end by the body at a point forwardly of the handle pivot axis. The other end of the multiplierbar extends rearwardly and forms a ratchet pawl which engages the ratchet drive of the feed mechanism.

The multiplier-bar is engaged by the forward extension of the handle at a point near the latters front end which bears upwardly against a mid portion of the multiplier-bar in a manner such that the latter acts as a lever of the third class with respect to pivotal movement of its pawl end with respect to its forward end. In this manner a downward displacement of the handle causes an upward motion of its forward extension. This upward motion is amplified by the multiplier bar so that its pawl end suffers a considerably greater upward motion than that of the forward end of the handle. This motion of the pawl is utilized as its back stroke so that with very small handle displacement the ratchet is fully enabled for a drive stroke.

The handle is firmly spring-biased toward an upward position, so that when released, by the grip of the operators hand, the handle returns upwardly and its forward extension returns downwardly. A pawl return member afiixed to the forward extension of the handle and 'disposed in engagement with the multiplier-bar, forcefully pulls the latter downwardly providing, at its pawl end, a drive stroke against the drive ratchet.

The disposition and upward extension of the die actuatwardly thereagainst.

ing anvil member is such as to actuate the embossing die responsive to upward displacement of the handle forward extension of a magnitude slightly greater than that required to back stroke the ratchet drive.

In this example of the invention, the feed mechanism comprises a tape magazine housing formed integrally with the body portion and disposed adjacent to and below the multiplier bar and forward extension of the handle. The tape output of the magazine is fed substantially directly to a cylindrical, rubber covered portion of the driving ratchet. The tape is held in firm frictional engagement with the upper part of the rubber portion of the ratchet by a smooth surfaced spring which bears radially in An automatic spacing centering idetent spring is also provided between the body portion and the ratchets of the ratchet drive to provide a positive placement and an audible tape advance-reverse index.

Further details of these and other novel features and their operation as well as additional objects and advantages of the invention will become apparent and be best understood from a consideration of the following description taken in connection with the accompanying drawings which are all presented by way of an illustrative example only and in which:

Referring to the figures in more detail it is stressed that the particulars shown are by way of example only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the structural concepts and principles of the invention. The detailed showing is not to be taken as a limitation upon the scope of the invention which is defined by the appended claims forming, along with the drawings, a part of this specification.

In FIG. 1 a tape embossing implement 12 is shown including a housing body 14 having a handle extension 16 formed integrally therewith. A movable handle 18 is pivotally afiixed to the housing body 14 and is journaled about a pivot axis 20 which is concentric with a manual tape advance knob 22. A cover plate 24 is secured to the top of the housing body 14 by means including a machine screw 28 and has a viewing window 26 formed therein for viewing the embossing tape after it has passed between the mated portions of a rotatable embossing die 30. The cover plate 24 is also adapted to form a pointer 32 which indicates to the operator which particular character impressing means is disposed in an actuating position with respect to the tape to be embossed. An emhossing tape dispensing magazine 34 is frictionally retained within the housing body 14 as will be shown more in detail in connection with the subsequent figures.

Note that the movable handle 18 in cooperation with the rigid handle extension 16 form a cooperating pair of hand grips adapted to be gripped by the operators hand and displaced pivotally toward each other to provide action for achieving the mechanical functions of the invention. It is further to be noted that the length of the

handle members

16, 18 are just long enough to be conveniently grasped by one hand; in practice this length may be approximately 3%".

In FIG. 2 the tape embossing implement 12 is viewed from above with the cover plate 24 removed. The rotary die 30 is seen to be journaled about an axis 36 which is carried by a shelf 38 formed integrally with the housing body 14. For purposes of properly positioning the rotary displacement of the die 36 its periphery is scalloped as shown and a detent spring 40 afiixed to the "cover plate 24 is provided. In this view the route to the embossing tape 22 is shown to emerge from within the housing body 14, travel between a leaf compression spring 44 and a rubber like tape drive cylinder (see subsequent figures), over a removable tape guiding plate 46, between the mated halves of the die 30, to the tape outlet 48 of the embossing implement.

A tongue member 50 afiixe'd rigidly to the housing body 14 functions in a manner to be more fully described below, in firmly securing the cover plate 24 to the housing body 14. The machine screw 28 and a machine screw along the axis 36 in cooperation with the tongue member 50 cooperatively provide a three point anchoring for the cover plate. The movable handle 18 and the manual tape advance knob 22 are illustrated in their respective positions as carried by the housing body 14.

In FIG. 3 the assembly is shown with the spring 44 removed, the tape 42 withdrawn, the tape guide plate 46 removed, and the die 30 removed from its supporting shelf 48. In this view the movable handle 18 is seen to extend beyond its pivot axis 20 into the interior of the housing body 14 and to terminate in a tension spring engaging hook 52. Also aflixed to this forward portion 54 of the movable handle 18 is a punch anvil 56 which as will be seen more clearly below is adapted to actuate the embossing die when the forward portion 54 of the handle is pivoted upwardly by pivotally displacing the handle 18 downwardly toward the handle extension 16 of the housing body. A firm tension spring 53 is interconnected between the engaging hook 52 and a lower portion of the housing body 14 to provide a biasing force for holding the handle 18 in its extreme upward location with respect to the housing body 14, as illustrated in FIG. 1. A pin member 60 forms a stop for the outward or upward disposition of the handle 18 by directly limiting the downward displacement of the forward portion 54 of the handle.

As indicated previously the manual tape advance knob 22 is pivoted about the axis 20. Also arranged about this major pivot axis and rotationally coupled to the knob 22 is a rubber like tape drive cylinder 62, and a driving ratchet wheel 64. The cylinder 62 and the ratchet wheel 64 are in this example a unitary assembly which is rotationally keyed to an axial extension 64 of the knob 22. The end of the axial extension 66 projects through an opening 68 in the wall of the housing body 14 opposite from the knob 22 and a machine screw 70 is threaded thereinto for retaining the assembly pivotally within the housing body 14.

It may be noted that although it requires a very small amount of tangential displacement of the forward portion 54 of the handle to actuate the rotary die 30 with the punch anvil 56, a significantly greater magnitude of action is required to drive positively the rotation of the tape drive cylinder 62. To this end, instead of requiring a sufiiciently large motion of the handle 18 or its forward portion 54, thereby causing the implement to be awkward and inconvenient, and subject to the disadvantages of the prior art, a handle action-multiplying-bar 72 is provided. The multiplier-bar is in this example pivoted near its forward end 74 about the pin member 60. Its rear end 76 forms a pawl 78 for actuating rotary motion of the driving ratchet wheel 64. As will be shown in more detail below, the opening in the multiplier-bar 72 for the pin member 60 is longitudinally elongated to provide a longitudinal freedom of movement for the multiplier-bar so that it may be pushed forwardly out of locking engagement with the ratchet wheel 64, when the knob 22 is advanced in the forward direction. The multiplier and its pawl 78 are urged toward and normally into engagement with the ratchet wheel 64 by a leaf spring 80 which will be shown in more detail below. A knob extension 82 aflixed to the multiplier-bar 72 and projecting through the side wall of the housing body 14 is provided for purposes of urging the multiplier-bar 72 forwardly against the spring 80, out of engagement with the ratchet wheel 64, to permit reverse rotation of the knob 22 when desired. To permit this longitudinal motion of the knob extension 82 and to permit its initial installation into the housing body an enlarged opening 84 is provided in the wall of the housing body 14.

Multiplier-bar engaging means aflixed to the forward portion 54 of the handle 18 for pivoting the multiplier bar about its pivot axis, pin member 60, are shown more clearly in the subsequent figures, to which reference will now be had.

In FIG. 4 which is a sectional view taken as indicated in FIG. 2, longitudinally through the major portion of the implemnet 12 and more particularly through the housing body 14, the assembly is shown with the cover plate 24 affixed and the tape 42 threaded through the implement from the tape magazine 34 to the tape outlet 48. Also illustrated in this view is a thumb-operated tape cutter 86 which may be urged against a spring (not shown) to pass a cutting blade 88 through the tape 42 near the implement outlet 48. A blade receiving recess 90 is provided in the cover 24 to provide full clearance for the shearing blade 88 in passing through the tape.

Additional details of the tape handling structure associated with the housing body 14 are illustrated in FIG. 4. For example, a tape threading tunnel 92 is provided which communicates from the output of the tape magazine 34 to the region of the tape drive cylinder 62. With this configuration it is seen that threading of the implement is provided by inserting the end of the tape 42 into the inlet 94 of the threading tunnel 92 and urging it therethrough until due to its curvature from having been wound into the magazine 34 the end of the tape 42 places itself between the tape drive cylinder 62 and its cooperating leaf compression spring 44. Once in this position, rotation of the drive cylinder 62 either by manual rotation of the knob 22 or by actuation of the ratchet wheel 64, the tape is automatically guided by the tape guide plate 46, and cooperating extensions 96 of the cover plate 24, to the region as shown between the halves of the rotary die 30 and thence by the funneling

surfaces

98, 100 past the cutter blade 88 to the outlet 48 of the implement. Once the tape 42 has been inserted and placed in contact with the driving cylinder 62, the magazine 34 may be slidably inserted into the magazine housing 102 which is formed integrally with the housing body 14; and further feeding of the tape in either the advance or reverse direction, out of or into, the magazine is automatic.

For purposes of accurate spacing of the embossed characters along the length of the tape 42 as well as for indicating the number of spaces of advance or reverse accomplished by the rotation of the manual knob 22 a detent spring 104 is supported by the housing body 14 in resilient engagement with the teeth of the ratchet Wheel 64 in a manner to permit its rotation in either sense of rotation.

Referring in more detail to the handle actuated driving mechanism it may be seen that the handle 18 is pivoted about the axis 20 and has its forward portion 54 extending into the forward regions of the housing body 14 where it is ultimately terminated by the spring engaging hook 52 which is engaged by the tension spring 58. The punch anvil 56 is shown in profile and the entire forward portion 54 is shown urged against its stop formed by the pin member 60.

The multiplier-bar 72 is shown pivoted about the pin member 60; and an elongated opening 106 is provided through the multiplier-bar 72 to permit the abovementioned longitudinal freedom of motion of the multiplierbar. The leaf spring is shown urging the multiplierbar into engagement with the teeth of the ratchet wheel 64. The knob extension 82 and its associated opening 84 in the housing body, which provide means for manually moving the multiplier-bar against the spring 80 and out of engagement with the teeth on the ratchet wheel, are also shown; and their action will be illustrated in detail in FIG. 6 below.

The forward portion 54 of the handle 18 is formed in a manner to be longitudinally relieved to permit the disposition of the multiplier-bar 72 therewithin. The opening thus formed through the forward portion 54 is transversely defined by an engaging ledge 108 and a return shelf 110.

In operation, when the handle 18 is pivotally displaced toward the handle extension 16, the forward portion 54 of the handle is moved against the force of the spring 58 toward the die 30. The engaging ledge 108 of the forward portion 54 of the handle engages the multiplierbar 72 and in the manner of a third class lever pivotally rotates it about the pin member 60 which causes its pawl end 78 to be moved also in the direction toward the die as well as forwardly against the force of the leaf spring 80 until it is disengaged from the tooth of the ratchet wheel 64, this action constitutes the backstroke for the pawl 78 with respect to the ratchet wheel. During this action the ratchet wheel and tape drive cylinder 62 remain stationary.

Referring to FIG. 5 the action just described is shown with the handle 18 pivotally displaced toward the handle extension 16 to the extent that the punch anvil 56 has engaged the rotary die 30 and has actuated a selected character impression portion thereof. The multiplier-bar 72 may be seen to have been pivoted about the pin member 60 by virtue of the engagement between the multiplierbar and the engaging ledge 108 of the forward portion 54 of the handle. The ratchet wheel 64 and the tape drive cylinder 62 still remain stationary. The multiplying action of the multiplier-bar 72 is impressively illustrated in this figure: although the handle has moved less than 10 degrees, the multiplier-bar has been pivoted approximately 45 degrees. This action in this example of the invention may be considered to be a combination of first and third class levers and requires approximately of an inch of total tangential displacement at the rear end of the handle 18 toward the handle extension 16-. The corresponding tangential displacement required merely to disengage the pawl 78 from one ratchet tooth and place it in engagement with the succeeding tooth is approximately A of an inch. It may be noted that prior art tools require approximately three times this magnitude of displacement to perform the corresponding functions.

The backstroke, or pawl releasing stroke, has been described above as occurring when the handle 18 is depressed toward the handle extension 16. The ratchet driving stroke occurs when the handle 18 is released by the operators gnip, and the tension spring 58 returns the forward portion 54 of the handle to its downward posi tion away from the die 30. As the forward portion 54 is so returned, the return shelf '110 engages the multiplierbar 72 and forcefully pulls it back into its position as shown in FIGURE 4. During the last few degrees of the pivot return motion of the handle 18, the pawl end 7 8 of the multiplier-bar 72 engages the succeeding tooth on the ratchet wheel 64 and advances the tape drive cylin- 7 der 62 with the force of the tension spring 53 exerted by the return shelf 110 on the multiplier bar 72.

Referring to FIG. 6 the action of the knob extension 82 on the multiplier-bar 72 is illustrated. The knob is pressed forward to move the multiplier-bar against the leaf spring 80 thereby sliding the multiplier-bar 72 longitudinally with respect to its pivoting pin member 60, in the opening 106 therethrough. With the knob extension 82 displaced all the way forwardly against either the rear edge of the elongated opening 106 or the opening 84 in the housing body '14, the pawl end 78 is totally removed from engagement with the teeth of the ratchet wheel 64 so that the tape drive cylinder 62 and the ratchet wheel 64 may be rotated by the manual tape advance knob 22 in either direction of rotation. The detent spring 164 provides a number of functions as described above, one of which is to provide an indication means to the operator of the number of spaces that the embossing tape has been advanced or retracted.

Referring to FIG. 7 a view showing the manual tape advance knob 22 and its axle extension 66 in elevation is presented. The axle extension 66 is shown journaled within the housing body 14 and the handle 18. The ratchet wheel 64 and rubberlike tape drive cylinder 62 are shown rotationally keyed to the squared mid-portion 112 of the axle extension 66 wherewith the knob 22 and the drive cylinder and ratchet wheel assembly are all rotated synchronously. The extreme end of the axle ex tension 66 projects through and slightly beyond the side Wall of the housing body 14, and a machine screw 70 is threaded therein to secure the rotatable assembly. For removal of the assembly, the screw 79 is removed and the axle extension is withdrawn through an enlarged opening 114 in the opposite side wall of the body 14.

In FIG. 8 the mating halves of the rotary die 51) are illustrated as journaled about a bushing 116 projecting downwardly from the cover plate 24. A machine screw 1 18 passes through an opening in the die supporting shelf 38 and aids in firmly securing the cover plate 24 to the housing body 14.

Referring to FIG. 9 a detailed view of the tape cutter 86 is shown in the state of parting the tape 42. The body 120 of the tape cutter includes a thumb detent 122 formed therein for urging the cutter blade 88 through the tape and into the blade receiving recess 90. A spring and a grooved track housed within the cutter body 120, not shown, serve to return the tape cutter 86 to the left as viewed in the drawing, thereby to withdraw the cutter blade 88 from the path of the tape 42.

Referring to FIG. 10 an exploded view of the assembly of the tape embossing implement 12 is shown for purposes of providing a clear illustration of the structural and functional relationships embodied in this particular example of the present invention. FIG. 10 is intended to provide the reader with a helpful reference to the form and disposition of many of the structural elements shown in more detail in the previous figures. To that end, here, as throughout the specification, like reference numerals have been applied to like elements for clarity of presentation.

The housing body 14 is illustrated with its handle extension 16, die supporting shelf 38, cover plates retaining tongue member 50 afiixed thereto. The other securing means for the cover plate 24 are also shown, namely, the

machine screws

118, 28. The pair of

holes

68, 114 for journaling the manual tape advance knob 22 and its axle extension 66 are seen to pass through the sidewalls of the body portion 14. Note the squared mid portion 112 of the axle extension 66 which rotationally keys the axle extension 66 within the ratchet wheel 64, drive cylinder 62 assembly.

The inwardly relieved nature of the handle 18 in the region of the pivoting center about the axle extension 66 and forwardly thereof, to permit the passage of the multiplier-bar 72, is shown. Particular note should be made 8 of the-engaging ledge 168 and the return shelf 110. The details of the multiplier-bar 72 may be seen with considerable clarity including its pawl end 78, its knob extension 82, its elongated opening 106 for the pin member 69, and its rearwardly biasing leaf spring 80. The handle returning tension spring 58 is shown adapted to be stretched between the spring engaging hook 52 of the forward portion 54 of the handle and a spring retaining pin member 124 which may be pressed through a pair of openings 125 near the bottom of the housing body 14.

The two halves of the rotary die 30 are shown with their key 126 and slot 128 {for rotationally connecting the two halves properly together. Note that the printed indicia on the righthand half, as shown in the drawing, are displaced 90 degrees from the embossing font shown on the lefthand half, to provide a proper correlation between the position of the pointer 32 and the particular portion of the die in actuating position with respect to the punch anvil 56. The detent spring 40- for the rotary die 36 and a retaining opening 130 for the tongue member 50 and the bushing 116 are shown in connection with the cover plate 24. The leaf spring 44, the central finger of which bears compressively against the rubberlike tape drive cylinder 62 as well as the removable tape guide plate 46 are illustrated in perspective in the figure.

Particular note may be made in connection with the tape dispensing magazine 34 that its broad sides are domed outwardly slightly. This feature provides retaining friction for holding the magazine within the magazine housing, not shown, in the housing body 14 and at the same time minimizes the friction between the sides of the magazine and the coiled tape 42 therewithin. By virtue of this means, the tape may be automatically retracted into the magazine merely by reverse rotation of the tape drive cylinder 62 with the manual tape advance knob 22.

In FIG. 11, a system, alternative to the E shaped leaf spring 44, is illustrated for compressively holding the strip tape in non-slipping, rolling contact with the tape drive cylinder 62'. The sectional View of this figure is taken in a manner similar to that of FIG. 5. In this example, however, the leaf spring 44 and the tape guide plate 46 have been omitted and their function is accomplished by a pressure roller 134 mounted on a roller shaft 136. The roller and shaft are supported against lateral movement by a pair of symmetrically disposed slots 138, one only of which is shown, formed in the top portion of the housing body 14. The downward displacement of the roller 134 and shaft 136 is limited by its pressure contact with the tape 42 or the tape drive cylinder 62 directly, when the tape is not in place the ends of the shaft 136 are depressed downwardly within the slots 138 by a respectively associated pair of tab extensions 140 which are formed, in this example, integrally with the cover plate 24. If desired, the material of the roller 134 may be rubber or rubber-like to improve its tape driving cooperative relation with the tape drive cylinder 62 and to minimize abrasion or other deleterious efiects on the tape 42.

The tape 42 is guided, in this example, after it leaves its region of compression between the two rollers (cylinder 62' and roller 134) by a side vane 142 which may be formed integrally with the handle 18.

The ratchet wheel 64' functions as in the previous examples except that here no detent spring 104 is employed for engagement with the ratchet teeth and valleys along the periphery of the wheel 64'.

A detent mechanism may be utilized externally of the tape drive cylinder 62' and ratchet Wheel 64 in the manner illustrated in the examples of FIG. 12 and FIG. 13. Each of these figures is a sectional view taken through the external manual tape advance knob 22' in a section plane perpendicular to the keyed axle 66' of FIG. 11 and viewed in the direction toward the housing body 14'. p

The inner periphery of outer portion of the knob 22' may be escalloped, as shown, to form a repetitive evenly spaced detent system. A floating detent ball resiliently urged radially outwardly is then provided in the form of a spring mounted roller 144 (FIG. 12) or ball 146 (FIG. 13). In the former case, the roller 144 is supported on the body 14 by a circularly formed flat mounting spring 148, which is affixed rigidly to the body 14' at the spring end 150. In the case of the ball 146 of FIG. 13, it is supported within a small housing cylinder 152 which is in turn aflixed rigidly to the body 14' by a pair of securing tabs 154. A coil spring 156 is disposed within the cylinder 152 and urges the ball 146 radially outwardly into a ball and detent engagement with the scalloped periphery of the knob 22'.

There have thus been disclosed and described the structural and operational features of an example of a tape embossing implement which achieves the objects and exhibits the advantages pointed out hereinabove. It is again stressed, however, that the scope of the invention is not to be limited by this detailed showing; but is to be measured by the terms of the following claims.
