' Application led March 6, 1924. Serial No. y697,283

To all whom t may concern.'

Be it;knownthat I, HERMAN Kunsfrnn, a citizen of the United States, residing at Detroit, county of Vayne, State .of Michigan, have invented certain new and useful Im- 'provements in Wireworking Machines, of which the followin is a speciication.

This invention re ates to improvements 1n wire Working machines. My improved Wire working machine is especially designed by me for the forming of holders for" oil-cans and the like, although readily adapted for performing other objects.

The main objects of'this invention are.

Y First, to provide an improved wire working machine which is automatic in its operations except for the feedingv of the pieces of' wire thereto and. .the yoperation 'of the control clutch.

Second, to provide an improved wire working machlne of the class described which is of very' large capacity Third, to provide an improved wire vrcrlim ing machine which is compact in structure and very durable in its parts. Objects pertaining to details and economies of construction and operation of my improvements will deinitelyv appear from the detailed description to follow.

I .accomplish the objects of my invention by the devices and means described in thefollowing specification. :Ihe invention is clearly defined and pointed out in the claims.

A structure embodying theA features of my invention is clearly illustrated in the accompanying drawing forming a part ofthis application, in which:-

In .the drawing ythe sectional views are taken looking in the direction of the little arrows at the ends of the section lines and similar numerals of reference indicate sim lar parts in all of the views The several mechanisms of the machine are actuated .from ihe shalt `.16 which is disposed longitudinally in 'the frame 17 com risiner a bed plate and sup ortin pedest-apiV Ttlie shaft 16 is rovided Ivgith a.

driving pulley 18'connecte to the'shat by means of the clutch 19 which is manuell controlled by the pedal 20. Since 'the clutc may be of an suitable ty I do no t illustrate or' describe it in detail herein.

The wire stock 21 is cut'to suitable length and, for convenience is stored in thehop er 22.11 The operator places the `Work 21 eion tween the forming pin 23 and the wi re \bend ing jaws 24, an adjustable stop 25 being provided to assist in positioning the work, see Figs. I and II. The forming pin 23 is vertically rcciprocable through the frame hed plate- 26, it being supported by a. lever 27 which is pivotcd at 28. The pin is held in normally projected position by means ot the spring 29 engaging the tree end ot the lever 27, see Figs. I and XII. J

The bending jaws 24 are mounted on the vertical pivots 80 disposed through the bed plates and provided u ith arms 32 to which the springs 31 are connected so that these jaws are yieldingly held open, see Figs. VIII and IX.

After a wire has been placed in position as shown in Fig. I the clutch is actuated by means of the peilal 20 thereby connecting the pulley to the driving shaft. 'ihe shaft 16 is provided with a cam 34 coacting with a roller 35 on the pin 36 carried by the slide member 37, the slide member 37 being reciprocatingly mounted in guides 38 on the bed plate 26, see Figs. I and IV.

rI`his 4actuating slide carries a pair of jaw actuating tappes 40, these tappets being pivoted On'th'e" slide at 41 and adjustably connected by the turn-buckle 42, see Fig. II As the slide advances on its work stroke the tappeis engage the jaws 24 swingingI them forwardwvith the work, bending it around the forming pin as shown in Figs. II and III, the jaws being completely closed in Fig. III.

As the wire is folded upon itself its arms are swung upon the guides 44 which are ontvvardly inclined so that the work is swung upwardly suflicientto clear the side vforming dies 45 and46. The .jaws 211. have grooved faces so that the wire is prevented from slipping from the As the arms ot the work swing over the dies 45 and 46, their ends are engaged by the downwardly facing inwardly inclined guides 48 which swings the arms downn-*ardly so that., when they clear the inner ends of the guides 44 of the side die menibers, the work swings down on toY the bed plate and into the range ot' the dies ruines io this position a jaw 45 and 46, see Figs. II and X. As the work 4f) carried by the slide member 37 clamps the bight of the work against the pin 23 holding it firmly `while the dies 45 and 46 are operating upon the wire. "the jaw 4t) is supported by a screw 52 threaded into the actuating slide 3T providing .means tor adjustirn.; the position ot' the jaw for different sizes o1 wire or dili'ercnt diameters.l oli' 'Forming pin, sce Vig. lll. 1-

ln this position the arms of the Wine lie at the sides of a form block 55 having side die taf-es or l'orm members 54 and 58. rlilo fares oi the dies 45 and 46. are a )propriately conformed to (react with the orming members ot the die block 55 to form the i offsets 56 and 59 in the wire bracket shown at 57, see Fig. VII.

The die members 45 and 46 are reciprocated in guides 6() by means ot pairs of rock levers 61 pivoted on shat'ts 62, rollers 63 on the lever being engaged by cams 64 on thc shaft 16, see Figs. I, X and XI. Since the opposed levers are actuated simultaneously the shaft is provided 4with an individual cam :for each lever and the levers occupy ofi'set portions so that each roller is out of range of the actuating cam for the opposed lever, sec Fig. The rollers are yieldingly held in contact with the cams bythe springs 65, see Fig. X.

The dies 45 are returned to open position by springs 66 lying in recesses 67 ot the dies, see Fig. XIV. The dies 46 are returned by similar springs 68, see Fig. II. The inward movement of the dies is determined by the tappet screws 69 on the actuating lever '61. After the actuation ot the dies 45 and 46 the;` actuating slide 37 is retracted or returned to initial position thereby disengaging the bending `aws and the clamping jaw 49 therefrom. ince the tappets 46 engage the forming jaws with a wedging action considerable force is required to start the actuating slide on its return movement. 'l`herelore, I provide a releasing cam 70, see Figs. I and IV. IVhen in initial position the roller 35 is yieldingly held in contact with the cam 34 by the spring 7l.

A thrust bearing roller engages the back of the cam 34 and supports the cam under the stress of the driving stroke ot the slide. The dies 46 constitute worlr clamps holding the work to the form block 55 While the folder arm 74 'folds the loop end of the wire upon the form as shown in Fig. V. The folder arm provided with a spacer 73 which lies between the arms otl the work holding 'them in alinement or preventing distortion thereof during this folding operation. lhe arm 74 is secured to thc rockshaft 7:7 which also carries the pinion 76` see Figs. IV. X and Xi. A rack 77 meshes with the pinion 76, the rack being carried by a slide member 78 reriprocating'on guides 79 on the under side otl the bed plate.

A cam 8() on the shaft -16 roar-ts with the roller 81 on the slide to actuate the slide. lo insure the disengagenunt of the wire from the forming pin the forming pin is retracted by means ot a cam 84 on the bar S3 carried by thc slide 7S. The slide 78 is returned to initial position by the springs 85. see Fig. l'. then the work has been folded upon the form as shown in Fig. V the top die member in the form of a roller S6 is actuated to contorni the end ol' the work to the ronraved top form member 55 0f the i'orni block 55, see Figs. V and Vl. this being the final forming operation on the work.

not attempted to illustrate or describe such The die member 86 is mounted on the lever 88 pivotcd at 89 and carrying an ad-` justable thrust screw 9,0y lcoacting with the rollerI 91 on the arnr92 pivoted at 93. A

plunger 94; reciprocatesy,vertically in the bed plate and is p rovidedf'with a roller 96 co'- acting with a camI 97 on the shaft 16. The lever 88 is returned to its initial position by means of the spring 98.

-After this final forming operation the folder arm and side die members 46 return the rock shaft 101 rotatable in a bracket 102..

j The arm 100 normally lies gin a recess in the face of the form block, the work being bent across the arm as it is formed around the ',die block, see Figs. V, VI and X. "When fthe completed work has been released the shaft 101. is actuated causing the ejector arm y to throw the work from the machine.

, The shaftv 101 is turned by a segment 101i meshing with the beveled pinion 105 on the shaft, see Figs. I and IV; The segment is secured to a shaft 106 provided 'with an arm `""10'7 connected by an adjustable link to a cam y parts being returned to initial position by.

lever 109 `pivoted at 110. vThe cam 111' on the shaft 16 coact-s with a roller 112 on the lever 109,'thereby actuatingv the ejector, the
