The cams I11‘ and I78 are secured on the shafts I4 and I5, respectively. In the operation of my machine, the wire blanks 42 are carried from their position on the 15 feed arms 4| to the form plate 26 by means of the feed carriage 29 which is actuated by the cam 38. The ?ngers #13, which form a V-shaped recess on- the front of the feed carriage, serve to, position the wire blanks against the form plate 20 where they are then formed and held against ment of the sprocket I54 causes the chain I53 to rotate the gear sprocket IM which acts to the hook. ’ The rollers are then returned to their ?rst position by means of the spring I30 which is under tension; and the frame is moved to its upper position by the cam I42. The ?nished hanger is next discharged down wardly from the form plate 26 by the downward 10 movement of the ?ngers I6‘! and I69 actuated by the cams I11 and I18 through the rocking levers I72 and I13. The springs I'II act to return these parts to their ?rst position. While I have shown my invention in but one 15 form it is obvious to those skilled in the art that it is not so limited but is susceptible of various changes and modi?cations without departing from the spirit thereof; and I desire, therefore, that only such limitations shall be placed there 20 displacement by the forming lugs 44. The form upon as are imposed by the prior art. I claim: plate and the forming lugs act to indent the 1. In a machine for forming wire- garment trouser support bar 208 of ‘the wire hanger 20!. The feeding movement of the feed carriage also ‘hangers, the combination with a form plate, of a feed carriage for carrying wire blanks to the 25 25 causesthe connecting links 43' to pivot the form ing arms. 46 about their axes to bend the wire form plate, forming arms pivotally mounted on blanks around the corners of the form plate 26. the underside of the feed carriage, upturned ?n The tension spring 5;»; acts to pivot the forming gers provided on the forming arms for engage arms M5 on the return stroke of the feeding car~ riage to take up the lost motion between the connecting links 48 and the pins 5|. While the wire blank is being held in position on the form plate by the forming lugs 44 and ?ngers 4'! of the forming arms 46, the shoulder 35 forming arms 56 and 57 are caused to move in wardly by their respective cams 6'6 and BI. The forming dies 58 and 69 act with the form plate to form the shoulder portion 202 of the hangers. The forward ends of the dies are provided with positioning lugs ‘I2 and I3 and slots ‘I4 and ‘It to accurately position the wire blank ends on the form. plate 26 and act with the tongue 11 to bend the ends of the wire outwardly from the form plate for the twisting operation. The form . ing dies hold the wire blank in position on the forming plate during the twisting operation, and the positioning lugs are arranged to carry the thrust of the wire ends during the twisting‘ opera tion. As viewed in Fig. 10, the wire ends are twisted in a clockwise direction in order that the lugs ‘I2 and ‘I3 will prevent displacement of the wire. In the twisting operation to form the twist 203 in the hanger, the cam 86 acts through the push rod 89, connecting link 92, lever 93, and shaft 8I to move the twister head 82 forward to receive the ends of the wire blank in the slot I20. The twister head 82 is then rotated by means of the cam I03 which acts through the lever III'I, con 60 necting link I69, gear segment III, and pinion gear I I3 mounted on the shaft 8I. After the ends of the wire have been twisted together, the twist er head is moved rearwardly by the cam 86. The springs III and IIB serve to overcome the mo mentum of the moving parts. The frame I2l of the hook forming mecha nism is next lowered to form the hook 203 of the hanger. The frame I2I is actuated by the cam I42 acting through a rocking lever I46 and connecting link M8. In forming the hook, the cam IGI acts through a rocking lever I5'I to move the gear sprocket I54 away from the frame I2I, thereby pulling the crank arm I26 until the stop screw I32 strikes the stop pin I29. The axis of 75 the roller I36 is then positioned in alignment ment with the ends of the wire blanks, and con necting links having their inner ends pivotally connected to the forming arms and their outerv ends engaging the frame of the machine for ac tuating the forming arms to bend the wire blanks around the form plate. 2.
