8 Claims.

My invention relates to a wire garment; hanger making machine and the objects of my invention are:

First, to provide a machine which will produce wire garment hangers from straight lengths of wire of suitable size and character, by hand power, the machine being therefore suitable for use by anyone requiring a considerable quantity of hangers;

Second, to provide this machine at reasonable cost and of very simple design so that it is very easy to operate;

Third, to produce a machine which will produce a satisfactory hanger from a minimum length of wire and without any inherent weakness due to improper twisting;

Fourth, to provide a machine which will require a minimum of repair and maintenance and of such sturdy construction that the machine will give long term satisfactory perform-, ance.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is a top plan view of my invention showing a wire blank properly inserted into the machine ready for forming, and also indicating in dotted lines one position of the hand crank assumed during the subsequent forming operation; Fig. 2 is a front elevational view of my machine with the hand crank in the position assumed for Wire blank loading; Fig. 3 is a top plan view of the left wire bending lever together with its roller supporting arm and the adjustable stop pins and the roller carried on said roller supporting arm; Fig. 4 is a side elevational view of the structure shown in Fig. 3; Fig. 5 is a top plan view of the twister head plunger actuating cam and hand crank assembly with the hand grip broken away; Fig. 6 is a right side elevational view of the same structure as shown in Fig. 5; Fig. '7 is a top plan View of the base of my machine all moving parts, except the lever actuating plunger, being removed; and Fig. 8 is a vertical sectional view of the structure shown in Fig. -7, the plunger not being sectioned.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings:

My machine is supported on a base I which will normally be held in place by attachment screws passed through the screw holes 2. This base I may be made with a step portion 3 best shown in Figs. 2 and 7 and referring to Figs. 7 and 8, a boss 4 with an upward extension 4a and. a forward extension 4b, and at the front end of the base another boss 5 which is centrally drilled to form a journal indicated at 5a, slotted at the top as at 5b in Figs. 1 and 7, and drilled as at best shown in Figs. 7 and 8.

The wire blank 6, Fig. l, is shown inserted in my machine, the two ends through the vertical slot 522 and the parts to form the shoulder portions of the hanger are shown bent at the outer ends of the stretcher arms 1 which are pivoted on the base I at their inner ends on pins Ilia. These arms 1 are forced apart to stretch the wire by a pair of links 9 which actually engage the wire, levers generally indicated at It] in Fig. 1 and the plunger l! slid-ably mounted in the

bosses

4 and 5 and forced in a longitudinal direction by cam action when the crank I 2 is moved from the starting position shown in Fig. 1 to the second position shown in dotted lines, all as hereinafter described more fully. Simultaneously with this action the forward ends l0?) of the levers Ill being suitably shaped for the purpose clamp'the wire blank against a forming plate l3 which is rigidly secured to the boss 3 on top of the extension 4a and behind the flange 4b as shown best in Figs. 7 and 8 and in Fig. 1. The plunger ll does not act directly against the levers l0 but against rollers llic rotatably mounted by pins llld on arms llle which are pivoted to the levers H? as at Hi This structure prevents undue friction and wear of the levers and piston and allows for easy adjustment by means of adjustable stop pins lily, this structure being shown clearly in Figs. 3 and 4 as well as being indicated in Fig. 1. As above stated the plunger II is moved longitudinally to spread the levers l0 and passing between said rollers and lockingthe arms 9 in extended position for holding the wire tight when the crank I2 is turned through degrees in a horizontal plane about the axis pin l2a since this movement carries the eccentric mm M pinned to the other end of axispin lZa into engagement with the forward end of the plunger H, as will be evident from an examination of Figs. 2, 5 and 6. The relation of the cam l with the plunger H is shownbest in Fig. 2 wherein the plunger. H is shown by dash lines and designated by the broken leader line in connection with the referencecharof the blank passing acter l l. Coming now to the twisting of the ends of the wire blank 6, this is accomplished by the rotary head generally indicated at in Fig. 1 and shown in more detailed form in Figs. 5 and 6. This rotary head I5 is rotatably mounted in the journal 5a of the boss 5 being held against movement in the direction of its axis by a pin tightly inserted in a drilled hole at 50 in Fig. 8, this pin engaging the groove lEb in the rotary head. The drilled recess I50, indicated in dotted lines in Fig. 6 is made to engage the short end of the wire blank as indicated in Fig. 1 while the long end of the wire blank is manually led around the pin i5d. as clearly shown in Figs. 1 and 5. A slot lfie in the rotary head corresponding with the slot 5b in the forward boss 5 allows the insertion of the ends of the wire blank when the crank I2 is in the loading position and centrally located of this slot [Be is a smaller slot [5 Fig. 5, which extends through the opposite side of the rotary head and in the position shown in Fig. l, the rotary head being locked by a key I la on the top side of the plunger ll against turning. This key 5 la is forced into the slot 95f by the manual lever l6 shown in Figs. 1 and 2, this lever being pivoted on a pin Mia and being of sufiicient length to have its handle section lfib register with the hand grip of the crank 12 when the latter is swung into the locked position. Finally, the hook I! positionally indicated in Fig. 1 and best shown in Figs. 2 and 6 may be integral with the hub section of the crank l2 and this hook I1, is operative in forming the hook section of the garment hanger. When the crank is moved into the position shown in dotted lines in Fig. 1 this hook I! rides over the projecting end of the wire blank 6 and when the crank is returned to the starting position the hook l6 preserves a sliding engagement with the wire bending it around the arcuate forming plate [8 in Figs. 2, 5 and 6 which plate It! is integral with the rotary head IS.

The operation of my machine will be clear from the foregoing. With the rotary head in locked position one end of the wire blank is inserted in the drilled recess I50 of the rotary head, the remainder of the wire being manually placed between the faces [0b of the levers and the forming plate l3 and at the same time around the ends of the links 9, the long end being led out to the twister head and loosely secured thereto between. the pin PM and the arcuate forming plate E8. The crank is then moved horizontally and the cam M will move the plunger H to force the levers ID to turn about their axis points Illa bending the wire between the faces lflb of the levers and the forming plate l3 and forcing the links 9 apart so as to stretch the wire blank into the desired shape. With the shoulder bends completed and this part of the wire blankheld tightly the next step is to turn the rotary head by means of the crank through two and one-half turns and then return the crank to its original position, the hook I! bending the wire blank end around the arcuate plate l8 and forming the hook of thegarment hanger. As the crank assumes this original position the manual lever I6 is pushed in the same direction as the final movement of the crank and this looks the rotary head in position facilitating the removal of the formed garment hanger and the insertion of the suc-. ceeding wire blank and at the same time release the rollers Illc. v

Though I have shown and described a particular construction, combination and arrangement of parts and portions, I do not wish to be limited to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.
