Fig. 20 isa diagrammaticfront elevation of the lpair, of wirel rolls, the shuttle and the wirecut off means, showing how a length of wire is drawn olf from the rolls of wire alternately.

In the practical embodiment of my invention which I have illustrated by way of example, it is intended that the machine operate at high speed and economically with a minimum of attention on the part of the operator. I therefore provide two separate and independent rolls 20 and2l (Fig. 20) of wire and further provide means preferably in the form of a shuttle for drawing a length of wire from each of the rolls 20 and 2| alternately and for cutting off the length of wire so drawn from the rolls to the proper length. I also provide means for rapidly operating upon the length of wire so cut to form all the bends in the wire during the time that the next length of wire is being drawn from the roll bye the shuttle and Asevered therefrom. I also provide a station spaced from the bending stations, at which the neck of the hanger is twisted while the succeeding length of wire is being bent. f A

My machine therefore preferably vincludes means for alternately drawing off and severing from the pair of rollsA of wire, predetermined lengths of such wire, means'for forming the bends in one of the lengths while the succeeding length of Wire is being drawn off a roll and severed.-

draw oif from the roll thedesired length tobe thereafter bent into the hanger.n Said shuttle further cooperates with va pair of wire severing cutters 28 and 24 which are set into operation alternately at the extreme end of each stroke of the shuttle.

As shown, the shuttle comprises a gripper support 25, (Fig. 5) provided with a recess 25 (Fig. 6) for the reception of the fixed guide bar 21, which bar is suitably supported as by means of the brackets 28 (Figs. 1 and 2) secured to the frame of the machine. A suitable gib 85 removably secured to the support 25 as by means of the bolts 5|, encloses the lowermost edge portion of the guide bar 21 and serves to adequately mount the shuttle for proper sliding movement on the guide bar. n

The shuttle is reciprocated by means of the continuously moving chain 82, (Figs. 1, 2 and 3), driven by the sprocket wheels 52 and 24. The sprocket wheel 52 is mounted on a suitable shaft rotating'in thebearing 55 in a clockwise direction as-viewed in Fig. 3. The sprocket wheel 24 is mounted on a suitable shaft rotating lin .the bearing 25 at the right end of the machine, said shaft carrying'the gear 81 meshing with the gear 88 on the main drive shaft 85 (Fig. 3). The main drive shaft 55 extends rearwardly of the machine and at its rear end, carries the pulley 48 which is rotated by suitable connections to a source of power not shown. It will be seen that on the continuous rotationof the pulley 45, the chain 82 is continuously moved in the direction of the arrow of Fig. 1. I

In order that the motion of the chain beimparted to the shuttle 22 to reciprocate said shuttle, a link 4| is pivoted at one of its ends 42 to the chain and at the other of its ends 48, is pivoted to the shaft u mounted in the shutue support 22. It will be-understood that as the end 42 of the link is carried around the sprocket wheel 33 from the lower part of said wheel to the upper part thereof, the shuttle is brought to rest momentarily at the extreme left end of its movement, and the movement thereof in the opposite direction, that is, toward the right, is begun. It is Just prior to the time that the direction of movement of the shuttle 22 is changed that the length of wire drawn to the left by the shuttle is severed from the roll 2| and raised into the position for the bending thereof.

Similarly, as the shuttle approaches its limiting position at the other end of the machine,

the length of wire drawn off the roll 20 is severed.`

The means for gripping the severed end of the wire, for drawing. off a length of wire from the roll, and for severing the length lthus drawn on will now be described.

Pivotally molmted on the reciprocating sup-- porting member 2 5, forming part of the shuttle, as by means of the upright studs 45 and 45 (Fig. 5) are the respective wire gripping jaws 41 and 48, said jaws being swingable in a horizontal plane on said studs. At its rear, the jaw 41 is provided with an inclined bevelled face 45 coopl erating with the oppositely bevelled face 58 of the relatively stationary wire gripping member 5| to grip the wire 52 at the proper time, said faces 48 and 55 providing a recess 53 therebetween for the ready entrance thereinto of the free end of the wire 52. 'I'he gripping member 5| is suitably secured to the support 25 as by means of the screws-,54. To normally urge the -jaw 41 into the wire gripping position thereof,

one end of the compression spring 55 is inserted into a suitable recess in the jaw and the other A end of the spring is inserted into a corresponding recess in the member 55 which is xed to the vsupport 25 and forms a part thereof.

It will be seen that the jaw 41 is normally rotated by the spring 55 about its pivot 45 into the position whereinthe rear face of said jaw is brought suilicientlyclose to the front face ofthe member 5| to permit the wire 52 to be adequately gripped therebetween, and that when the Jaw 41 is rotated in a clockwise direction as viewed in Fig. 5 against the action of the spring 55, the wire gripping face of the jaw is carried away from .the cooperating face of the member 5| a sumcient distance to release the wire gripped therebetween. Such release of the jaw occurs preferably just before the: shuttle 22 is at the extreme right end of its path of movement after having drawn the wire 52 toward the right from the roll 2|| a predetermined distanceso that the proper length of such wire may be severed from the roll.

The jaw 48 is provided with a bevelled face 51 similar to the face 49 of the jaw 41, and with az spring 58 similar to the spring 55 and operating A vmounted on the guide bar 21 as by-means of the gib 55. At the end of the shaft 55 opposite from that on which the cutter 22 is mounted, a cam lever 55 is xed, said lever being pulled by the spring,51 in the proper direction to position the cutter 2 3 out of the way of the wire. Said cam lever 55'is provided'withan extension 58 having a cam-engaging surface 58 adapted to be engaged by the cam-15 on the shaft 1|. 'I'he shaft 1| is continuously rotated through the bevel gear 12 mounted on said shaft, which gear engages the bevel gear 13 on the front end of the shaft 14,

:the shaft 14 being in turn rotated throughthe gear`15 meshing with the gear 15 on the shaft.

Extending from the cutter block 54 is the spring-holding rod 11 passing through the extension 18 on the guide bar 21 (Figs. 1 and 3) and provided at its outer end with the adjustable stop nuts 15. The spring 85 is interposed between the extension 18 and the cutter block 54 and is compressed when the cutter block is moved along the guide bar 21 under the action of the shuttle 22. A cushion 8| of suitable resilient material such as rubber or the like is secured to the cutter block 54 and is arranged to be engaged by a projection as 82 on the shuttle during the last part of the movementof the shuttle toward the left. The wire 52 is passed loosely through a suitable opening 83 in the cutter block and in the cutter lever 6B and before the severing thereof is gripped between the jaw 41 and the member'5l (Figs. and 20) during the movement of the shuttle toward the right.

It will be understood that the cutter block together with the cutter and the cutter lever carried thereby and above described are mounted on and have a limited longitudinal movement on the left end of the guide bar 21, and are used in connection with the Asevering of a length of wire 52 from the roll 20, being also used in connection with the gripping of the severed end of the roll by the shuttle when the shuttle is at the extreme left end of its movement. However, a similar cutter block 83, cutter 24 and cutter lever 84 are slidably mounted at the right end of the guide bar .21 and being similarin all respects to the first-mentioned cutter block and its parts, the above description of the former will suiiice for both.

The cam on the shaft 1| is similar to the cam 10 and operates the cutterlever 84 in a similar manner.

In the position of the parts shown in Figs. 1

. and 3. a length of wire 85 has been drawn by the shuttle off the roll 2| of wire and has been'released by the shuttle, and the shuttle is in its position at the end of its movement toward the left. In this position, 4the projection 86, which extends forwardly'from the upper part of the jaw 48, has been and still is eng-aged by the xed adjustable stop 81. Said jaw is therefore swung about its pivot 46 and has released the wire 85. The shuttle, in the last part of its movement toward the left, has engaged the cushion 8| and has moved the cutter block 64 with it toward the left against the action of the spring 80, thereby exposing the right end portion lof the wire 52 at the right beyond the cutter block 64. The severed endportion of the wire has therefore entered the recess 53 and forced itself` between the jaw 41 and the member 5| to be gripped therebetween under the action of the spring 55. The cutter 24 is now rotated by the cam 10' to sever the length of wire 85 before the shuttle 22 starts on its return movement toward the right with the wire 52 grippedtherein. The point of release of the wire end by the shuttle being determined by the adjustment of the stop 81, the length of the severed wire may be accurately predetermined.

It will be understood that the wire 52 as it comes from the roll is straightened by suitable straightening rollers designated generally by the numeral 88 or by a. suitable straightening machine of any well known type. Similarly, the wire 85 has been straightened by the straightening machine or rollers 89 prior to its passage through its cutter block 83 so that the severed lengths of wire are sufciently straight to be properly operated on by the various instrumentalties for advancingand bending the lengths.

As the shuttle 22 moves toward the right with the wire 52. gripped thereby, a predetermined length of said wire 52 is drawnoif the roll 20, the precise length beingdependent upon the adjustment of the jaw stop 90', which is carried by a suitable bracket 9| secured to the frame of the machine and which operates to engage the lower extension 92 of the jaw 41 at the proper time to open said jaw and tof'release the wire 52 preparatory to the severing thereof by the cutter 23 through the operation of the cam 10.

The jaw stop 81 is carried by an arm 93 secured to the chainguard 94. The upper chain guard 94 together with the lower chain guard 95 are supported as by means of the brackets 96, 91

-tion at all times.

It will be seen from the above description that the shuttle in its alternative movements toward the right and toward the left flrst draws a length of wire 52 from the roll x20 and preparatory to its return movement toward the left, said length of wire is severed by the cutter 23 and the severed length 52 is released, whereafter as thel movement of the shuttle in the same direction is completed, it grips the end of the length of wire 05 and draws off a predetermined length of such wire from the roll 2|, which length is again severed and the operation repeated whereby the proper straightenedlengths of wires are alternately drawn off from the rolls and positioned ready for the bending and twisting thereof into hangers.A

The means for forwarding the severed length of Wire into bending position will now be described.

Just prior to the severing of each length of wire, means are positioned for engaging the wire when severed and for forwarding saidwire into position for the bending thereof. Said means comprises a plurality of similar spaced wire-engaging fingers |00, each provided with a wirereceiving recess I0|. Since the ngers are similar in construction and operation, a description of one of said fingers'and of the means for operating it will'sui'lice for all. The vwire supporting nger |00, best shown in Fig. 8, is pivoted as at |02 to the `finger lever |03. 'Said lever |03 is pivoted as at |01 to a suitable bracket secured to the frame of the machine and is provided with a cam roller |04 engaging the surface of the cam |05 mounted on the shaft 1|. The spring |06 connected to the finger |00 and to the lever |03 urges said finger toward its uppermost position as viewed in Fig. 8 and against the pin stop |08. The cam |05 is so shaped that the pivot |02 and the finger are normally in their uppermost positions. In said position, the extension |00 of the finger engages a face of the frame 29, thereby insuring against `movement of the intermediate fingers |00 under the stresses of the bendingoperations upon the wire later to be described and serving to hold lthe ngers into theiruppermost positions to maintain the intermediate portion of the wire against flexing. y

When, however, the length of wire to be severed by either of the cutters 23 or 24, then the roller |04 enters the depressed portion of the cam |05 whereby the ngervlever and the nger carried thereby swing downwardly about the lever pivot |01 to carry the nger below the length of wire and into the position wherein the wire when severed rests in the recess |0|. Immediately after the Wire has been severed, the lever |03 and the finger |00 are swung upwardly to carry the length of wire into the position wherein the first bend is made therein, as shown in Fig. 8. In this position, the Wire touches the bottom of the anvil shaft |09 'and liesforwardly of the transfer finger ||0. Said transfer finger is bent partly around the anvil and provides a stop face or shoulder against which the wire may be bent, said finger when moved relatively to the anvil shaft also serving to eject the bent wire at the proper time from the bending station thereof to the neck twisting station, as will 75' is Iabout be more fully explained hereinafter. Theilnger H0 is mounted on the shaft IH, which shaft is secured at its rear end to the plate H2 for forward and rearward movement therewith' as a unit and relatively to the rotatable anvil shaft |03. The anvil shaft 33 extends rearwardly to a point near the rear of the machine (Figs. 2 and 3), and is there provided with a pinion H3.

It being understood that a pair of first bends H4 and H4 are made simultaneously in the length of wire, it may be stated that the mechanism for performing the first bend at the right of the hanger is substantially identical with that just described for performing the ilrst bend at the left of the hanger.

'I'he right hand first-bend mechanism comprises the anvil shaft H6 similar to the anvil shaft |03, the finger H6 similar to the ng'er H3. and the finger shaft H1 similar to the shtv At the rearA end of the anvil shaft H6 is Hi. mounted the pinion H3 similar to the pinion H3.

On the front end of the anvil shaft |03 is fixed the'crank H3 carrying at its outer end the rotatable grooved roller |20 having the circumferential wire-receiving groove |2I therein. Similarly,.the anvil shaft H6 carries at its front end, the crank |22 which in turn carries the grooved roller |23.

In order to rotate the anvil shafts |03 and H6 simultaneously to vswing the cranks H3 and. |22 and-thereby to carry' the straight wire held by the fingers |00 around the respective anvil shafts to formthe first bends in the wire, the anvil shaft pinions H3 and H3 are simultaneously rotated in opposite directions at the proper time. To eect such rotation of the pinions, the rack bar |24 is provided with teeth [|26 in its lower edge for engaging the pinion H3, the extension |26 of said bar "being provided with rack teeth |21 in its upper edge engaging the pinion H3. nThe rack bar |24 is held in engagement with the pinion H3 by means of the roller |23 pivoted to the machine frame, while the extension |26 is similarly held in engagement with the'pinion lH3by means' of a similar roller |23. Secured'to the rack bar |24 as at |30 is the short link |3|, the other end of said link being connected to the oscillatory crank |32, (Figs. 3 and 4), the crank |32 being pivoted at its lower end on the shaft 33 (Figs. 3 and 4).

I'he crank |32 also carries the cam roller |34 engaging the cam |35 on the shaft |36. Said shaft |36 carries at its rear end a gear |31' meshing with the gear 15 and rotated thereby continuously. Y

It will be seen that during theoperation of the machine, as the shaft |36 is rotated, the crank |32' will be oscillated, thereby reciprocating the rack bar |24 and its extension |26 and rotating the pinions H3. H8, and the anvil shafts |03, H6 respectively carried thereby to carry the roll- 'ers |20, |23 and the wireend portions resting in the respective grooves thereof around the anvil shafts to form the bends H4, H4' and 'to bend the wire into the form shown in Fig.` l5.

The left inclined portion |38 of the wire is shorter than the right portion |39, the portion |30 however, lying below the bending striker |40 (Fig. 9) while the portion V|39 similarly lies below the striker |4I. During the bending of the portion |39 (see Fig. 10), said portion engages the bevelled top 260 of the retracted striker and slides downwardly thereon as the bending proceeds until it slides of! the striker'top, whereby the portion |33 becomes positioned below the hook bending pins |30 and |32 later to be described, as shown by the dot-dash lines of Fig. 1.

Said strikerslll and' I4| are simultaneously operatedto form the second and third bends in the wire. The second bends |42 and |43 are formed by bending the wire about the movable second bend anvils |44 and `|46 respectively, while the third bends |46 and |41 are simultaneously formed by the strikers in cooperation with the fixed die |43 (1315.19). The rear ends of the-second bend anvils |44 and |46 are secured to the plate H2. i

Eachof said anvils is provided with a reduced front end, thereby forming shoulders |43 and |63 respectively. against which shoulders the wire portions 33 and |33 respectively rest after the vformation of the first bends H4, H4' (Fig. 10). 'I'hestriker |46 is mounted for reciprocatory movement in the iixedgulde |6| (Figs. 1 and 9). At its upper end. said striker is connected by the link |62 to the crank |63 on the shaft |64. Near the rear end of said shaft |64 is carried the shorter crank |66 (Fig. 4) to the outer end of which is secured one end of the connecting rod |66, the'other end of said rod being secured to one end of the bell-cra'nk-lever |61 pivoted on the anvil shaft |33. The roller |63 carriedby saidy bell-crank-lever engages the cam |63 on the shaft |36,'said"roller being held in contact with the cam by means of the spring |60 xed at one end as |6| to the machine frame and at its otherend as |62 xed to the crank, said spring urging the crank |66 in a counterclockwise direction as viewed in Fig. 4 and therebynormally maintaining the striker |40 in its retracted position.

The means for operating the striker |4| being substantially identical with the means just described for operating the striker |40, the description thereof need not be repeated except to say that the cam |63 for operating the striker |4I is vmounted on the shaft 14.

ably provided with a recess |63 into which the end portions |33 and |33 of the wire are respectively received. As the striker |40 moves downwardly in its guide under the action of the cam |69, the wire |33 is engaged and bent around the anvil. |44 and against the shoulder |43 thereof, the wire being carried past the. anvil and into the recess |64 of the die |43, said recess being provided with an upright wall |66. The end part |66 of the wire is bent into substantiallyupright position by`the striker |43 and the walll |65 As to the right end portion |61'of the wire, said end portion is bent by the striker and die Y |43 into a position wherein it rests against the surface of the hook-forming anvil and below the hook-forming rollers |30 and |32, as previously mentioned." 'I'he hook-forming anvil comprises the hollow outer shaft 63' carrying at its rear end,

1 the pinion |69 (Figs. 2, 4, and 11). Rotatably mounted inside-of the outer shaft |60 is the innershaft |10 extending toward the rear of the machine a thereprovided with the pinion |1|. Meshing wi h .the pinion |63 on the outer shaft |60 is the rack bar |12 guided in its reciprocatory movement by the roller |13. ,The lever |14 pivoted at one end to the shaft '|33 and at its other end, connected to the rack bar |12, carries a roller |15 engaging the cam |16 on the shaft |36.

It willbe' seen that on the operation of the machine, the lever |14 is oscillated, thereby caus- CTI Carried by the front end of the outer shaft |68 is the hub |18 carrying the pin |19 on the pro- `iection |80 thereof (Figs. 1, 9 and 11) Similarly, the hub |8| is carried by the front end of the inner shaft |10 and is provided with the bending pin |82. Said pin |82 is swung by the rack bar |11 in the direction of the arrow of Fig. 9 to form the neck or lowermost bend |83 (Fig. 17) in the hook |84 of the hanger, while the pin |80 is operated by the rack bar |12 to bend the hook |84 from the end portion of the wire about the hub |8|, said pin |80 being moved in the direction of its arrow and in the direction opposite to that of the movement of the pin |82. It will be understood that on the return movement of the racks, the pins |80 and |92 are moved back to the initial positions thereof shown in Fig. 1.

All of the bends having thus been completed, the thus bent hanger is moved forwardly into position for the twisting operation upon the neck of the hanger. The means for so moving the hanger into the twisting position will now be described.

It being remembered that the second bend anvil shafts |44` and |45 as well as the flngershafts and |1 are secured at their rear ends to the plate ||2 and'that the hanger rests against the shoulders |49 and |50 of the shafts |44 and |45 and against the, fingers .and ||6, it will be seen that movement of the plate ||2 forwardly will move the anvil shafts |414 and |45 and the fingers ||0 and' I6 as a unit to move the bent hanger 01T the hook-forming hub |8| and toward the front ends of the rst bend anvil shafts |09 and I into the position shown in Figs. 2 and 11.

Such movement of the plate |2 and the shafts carried thereby is caused by the lever |85 which is connected to the plate I2 by the link |86 and the plate projection |81. The lever |85 is pivoted at its lower end (Fig. 4) on the pivot shaft |88 carried by a suitable bracket |89 mounted on the shafts |33 and 209. A cam roller |90 is carried by the lever |85 intermediate its ends and engages the face of the cam |9| on the shaft |36 (Figs. 3 and 4), the spring |92 (Fig. 3) serving to maintain the roller in engagement with the cam.

It' will be seen that during the rotation of the shaft |36, the lever |85 is oscillated at the proper time to carry the plate ||2, the parts carried thereby, and the bent hanger into the twisting position shown in Figs. 2 and 11. On such forward movement of the plate ||2,` however, the hanger previously arranged in the twisting position and which had .previously been twisted, is forwarded on to the fixed tubular hanger support |93. Said support is carried.. by the arm |94 (Figs. l and 2), suitably secured at its lower end to the machine frame and bent to clear the hangers accumulating onthe support |93.

lThe means for 4forwarding the twisted hanger on to. said support on the 'forward movement of the' plate ||2comprises apair lof trigger latches |95, said latches being arranged coaxially of the shafts |44 and |45, respectively, and being similar in construction, a 'descriptionY of one will -sumce for both. A plate |96 is suitablysecured in a groove in the lower part of each of the shafts |44 and |45 and extends forwardly thereof. At its forward end, the plate |96 carries a grooved bar |91, in the groove of which is pivoted the latch |95 for swinging movement ina vertical plane and against the action of the spring |98 (Fig. 11). The rearend of the upper surface of the latch is bevelled and terminates in a shoulder adapted to grip the hanger. It will thus be seen that on the forward movement of the plate ||2, the latches |95 grip the twisted hanger at a point adjacent the bends |42 and |43 thereof and forward said' hanger from the twisting position on to the support |93 while the next hanger is being forwarded by the shoulders |49 and |50 and the v fingers ||0 and H6 along the die v|48 into the twistingposition.

After the hanger to be twisted has been positioned as above described, the lever |85 is oscillated by its cam to retract the plate 2, the shafts |44 and |45 and the fingers ||0 and ||6 into the position where the bending operation may be performed upon the next hanger while the twist in the hanger just forwarded into twisting position is being performed. Part of the supporting means for the hanger to be twisted having thereby been removed, it becomes advisable to additionally support the hangerv to permit the twisting operation to be properly carried out.

As shown particularly in Figs.1, 2, 11 and 119, said auxiliary or additional supporting means takes the form of a pair of reciprocatory slides 200 and 20|, each sliding' in an upright groove in o ne of the upright faces of the die |48 and each having a suitable recess 202 in the upper edge thereof for engaging the substantially horizontal portions 203 and 204, respectively, of the hanger- (Flg. 18).

Y The slidable hanger suports 200 and 20| are connected at their lower ends to the lever 205,

one end of which is interposed between said slides and the other end of which is connected to the connecting rod 206, said lever being pivoted as at 201 to the frame of the machine (Figs. 2, 3, 4

and 11). At its lower end, the connecting rod 206 is pivoted to the bell-crank-lever 208 which is mounted on the shaft 209 and'one arm of which carries the roller 2|0, engaging the cam 2|| 0n the shaft 14. It will be seen that on the rotation of the shaft 14, the bell-crank-lever 208 is oscillated at the proper time during the retraction of the plate ||2 to lower the connecting rod 206 and thereby tooscillate the lever 205 and to raise the supporting slides 200 and 20| into the proper rosition to support the untwisted hanger in the twisting position, the parts 203 and 204 of the hanger entering the recesses 202 of the slides.

The mechanism for performing the twisting operation upon the wire parts |66 and |61 to secure'said parts together to form the twist |99 (Fig. 18) willnow be described.

Said mechanism includes the bearing 2|2 (Fig. 2) secured to the frame of the machine and supporting the twister sleeveV 2|3 forivertical reclprocation therein. Said sleeve is provided with an-elongated pinion portion 231 above which is .securedthe block 2|4 suitably heldv against rotaton, and the collar 2|5. ,The lower end of the sleeve 2|3 is grooved for the arrangement therein of the gripping jaws 2|6 and 2|1 which are pivoted to the sleeve as at 2|8 and 2|9, respectively. In a suitable circumferential recess around the jaws and the sleeve is arranged the ringspring223whichtendstodrawtheupper endsofthejawstowardeachotherandthereby to spread the lower ends of said laws apart, the.

upper ends of the :laws being suitably rounded forthepllrposoontobedescribed. '1herod22l is slidably mounted for reciprocation within the sleeve 2|3 and at its lower endl, terminates in a conical portion'222 adapted to enter between the limit the relative movement of the rod and sleeve a in either direction.

Movement of the sleeve 2| 3 in a downward direction is limited by the adjustable stop bolt 223 secured to the block 2|4 and adapted to engage the stop block 223 secured to the upper face of the bearing 2|2. The compression spring 221 is interposed between the collar 2|3 and the connecting member 223 at the upper end of the rod 22|. Said connecting member connects said rod to the links 223 which are in turn connected to the'lever 233 pivoted to the bracket 23| -as at 232. The left end of said lever 233 as viewed in Fig. 2 is connected to the upper end of the rod 233. the lower end oi said rod being in turn connected to the bell-crank-lever 234 (Fig. 4) carrying the roller 233 which engages the cam 233 on the shaft 14.

It will be imderstood that on the rotation oi! the shaft14, the bell-crank-lever 234 is oscillated at the proper time to reciprocate the rod 233 and thereby to oscillate'the lever 230, as a result of which therod 22| is reciprocated at the proper time. 'I'hat is, after the hanger has been posiv *ioned as hereinbefore described in the position wherein it is to be twisted, the rod 22| is moved downwardly together with the sleeve 2|3 as a unit, it being- 'ilnderstood that the pfn 223 isk at e upper end ofthe slot 224 and that the conical rortion 222, at the upper end of the slot 224 and that the conical portion 222, at the lower end ofd the rod. is above the jaws, whereby said jaws are held open and pass about the hook part |34 of the hanger, the spring 221 serving to transmit the motion of the rod to the sleeve. When, however, the sleeve and the block 2|4 have reached the position wherein the jaws 2|3 and 2|1 are arranged on opposite sides ofthe hanger hook and 0f the upper ends of the parts |33 and |31 of the hanger, the stop 223 strikes the stop block 223, thereby halting further downward movement of the sleeve 2|3. Continued motion of the lever 233, however, causes further downward movement -f the rod 22| against the action of the .fpring 2 21, thereby projecting the lower conical end 222 of the rod between the upper ends of the jaws 2|3 and 2|1, causing said jaws to swing about their pivots and to close the lower ends of said jaws on to the hook of the hanger, the pin 223 at this time moving to the lower end of the slot 224. Y

While the jaws are maintained in their hookgripping positions, the sleeve 2|3 and the jaws carried thereby are rotated to perform the twisting operation and to form the twist I 33.

For thus rotating the sleeve, the gear 238 meshing with the pinion portion 231 of the sleeve is provided. Said gear 238 carries the Geneva. wheel 239 mounted on the shaft 240 supported in the bracket 23|.' 'I'he Geneva pin 24| is carriedl by the crank 242 mounted on the shaft 243, also supported by the bearing 23|. On the same smamatnebenuesrm enmm'gmebevell gear 243 on the shaft 243 (Fig. 2). At its rear,

end, the shaft 243 carries a suitable sprocket wheel driven by the 241. which chainpasses about and is driven by a suitable sprocket wheel on 'the shaft 33.

It will thus be seen that the sleeve 2|3 is inter- 'mittently rotated through the Geneva movement and the driving means therefor Just described to perform the twisting operation. After the twistthereof to engage the upper end of the slot 224,

then the sleeve also moves with the rod as a unit to withdraw the jaws from the hanger hook and thereby to free the thus twisted rod for the forwarding thereof by the latches |33 on to the hanger support |93 on the next forward movement of the-plate H2.

Said forward movement of the plate ||2 not only moves the twisted'hanger on to the support |33 but also moves the succeeding hanger into twisting position, as has been hereinbefore indicated so that the parts may be repositioned while the twisting of 'one hanger is going on for the bending operations upon another hanger, and thereby to permit the machine to work at high speed.

`It will be seen that I have provided a machine wherein by the provision of a shuttle drawing wire from two separate rolls, the -time during which the shuttle draws a length of wire from one roll is used for the purpose of bending up the wire previously drawn by the shuttle from the other roll. It will also be seen that by providing a separate twisting station, the bending operation upon one wire may proceed simultaneously with the twisting operation upon another previousiy bent wire and that I have provided a machine designed to automatically produce wire hangers at high speed eiiiciently and economicalLv. l
