MACHINE FOR FORMING GARMENT HANGERS.

Application filed January 3, 1922. Serial No. 526,466.

To all whom it may concern:

Be it known that I, BENJAMIN J. RYAN,

a citizen of the United States, residing at Dallas, --in the county of Dallas and State I of Texas, have invented certain new and useful Improvements in Machines for Forming Garment Hangers, of which the following is a specification.

This invention relates to new and useful I improvements in machines for forming garbending arms a swing sufiicient to' effecttheir operation. a

A construction designed to carryout the invention will be hereinafter described together with other features of the invention.

, The invention will be more readily under-,

stood from a reading of the following specification and by reference to the accompanying drawings, in which. an example of the 35 invention is shown and wherein:

Fig. 1 is a plan view of a machine constructed in accordance with my invention, showing in dotted lines the manner in which a piece of wire is bent by the wire bending arms,

Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1,

Fig. 3 is an underside view of the central A portion of the table, showing means for swinging the wire bending arms,

Fig. 4 is an enlarged detail of the hook forming device, a

Fig. 5 is an enlarged detail of the hook forming elements in their operative position,

Fig. 6 is an enlarged detail of one of the wire bending arms,

of the wir are broken is to be understood that Fig. 7 is an enlarged longitudinal sectional view of the wire twisting device,

Fig. 8 is an enlarged face view of the wire twisting head,

Fig. 9 is a plan view of the arm shown in Fig. 6,

Fig. 10 is an enlarged detail of one of the arm swinging 'pulleys,

Fig. 11 is a sectional view of the pulley taken on the line 11-11 of Fig. 10,, and a Fig. 12 is an enlarged detail of a finished garment hanger formed by the machine.

In the drawings the numeral 10 designates an elongated table supported by suitable legs' 11 at each end. Disposed in spaced relation along the rear portion of the table are corresponding wire bending arms 12 with integral ears 13 at their inner ends. The ears are fixed to vertical posts 14 which ex tend above the same and thru the table, said posts being loosely confined in suitable apertures, whereby the wirebendin'g arms are pivoted. As is best shown in Figs. 6 and 9, the upper edge of each arm extends above the ear throughout its length, while the outer ends of the arms are bent forwardly and providedwith wire receiving notches 15. When the arms are in normal position, as is shown in Fig. 1, it will be seen that a straight piece of wire 16 may be placed longitudinally of the arms so as to lie in the notches 15 and to rest on the said ears between the posts 14 and the inner edges of the arms. As is shown in Fig. 1,the ends away; however, it the wire is disposed so that one end projects farther from the end of the table than the other, whereby a long and a short end of the wire are formed when the arms 12 are swung forwardly. Guide brackets 16 are spaced apartand mounted on the table intermediate the posts 14, so as to engage the rear edge of the wire and prevent the latter from bowing when the arms 12 are swung.

Mounted on the'front central portion of the table are upright forming pins 17, while a pair of guide pins 18 are mounted intermediate the pins 17. An elongated vertical deflector blade 19 has its rear end pivoted in a suitable bracket 20 secured to the table, and is directed between the guide pins 18 in close proximity to the same. The forward lower edge of the deflector is :curved upwardly, while the deflector is adapted to be swung upwardly upon its end, as 1s shown in dotted lines in Flg.

For operating the wire bending arms 12, I mount a split pulley 21 on the lower end of each pivot post 14, as is shown in Fig.

a foot lever 26 which extends forwardly and.

is hinged to a member 27 secured to the underside of a cross bar 28 extending between the rear legs 11. A suitable treadle 29 is mounted on the forward end of the lever 26, and it will be seen that by depressing the latter with the foot, the pulleys undergo a rotating movement, whereby the arms 12 are swung forwardly. In order that the said arms may return automatlcally to the1r normal position when the lever 26 1s released, I provide a coiled spring 30 in the hub 31. of each pulley. As is shown in Fig. 11, each spring surrounds a post 14 and has one end secured thereto, while the other end is embedded in' the table. It is evident that when the foot lever 26 is depressed, said springs are wound under tension, and it is obvious that when said lever is released, the unwinding action of the springs causes the wire bending arms to swing to their normal position. Although I have illustrated and described the preferred means of operating the wire bending arms, it is to be understood that the invention is not limited thereto, and that any other practical means may be employed for this purpose.

When the arms 12 are swung forwardly, it will be seen that the wire is bent round the posts 14, and that the ends of the wire strike the sides of the deflector 19, While the outer curved ends of the arms press the wire against the pins 17 and 18, whereby the ends are deflected forwardly, as is shown in dotted lines in Fig. 1. Upon this operation it will be seen that a long and a short end are formed, the next operation being to twist the latter upon the former to provide a neck for the hanger.

For this purpose I provide a wire twisting device comprising a sliding bar 31, slidable in guides '32 provided on the, underside of the table. a bearing post 33, journaled in which is a tubular shaft 34 provided with a crank han- The outer end of the bar has die 35 on its outer end. The shaft is slidable in the post and has an enlarged head 36 directed toward the forward end of the deflector 19. The face 37 of the shaft is concave and is in alinement with the forwardly directed ends of the wire, said face having an oblong slot 38 in its center for receiving said ends. An elongated lug 39 projects from the underside of the .head toward the inclined portion of the defiector.

By sliding the bar 31 inwardly with considerable force, the ends of the wire are received in the shaft, while the lug 39 strikes the inclined edge of the deflector and swings the latter upwardly to a position as is shown in dotted lines in Fig. 2. Upon this operation the head 36 strikes the extreme outer ends of the arms 12 which causes the wire to be pressed firmly against the pins 17 and 18. It will be readily seen that by revolving the shaft 34 by the crank handle 35, the short end of the wire is twisted together with the long end, thus providing a neck 40 (as is shown in Figs. 5 and 12) and leaving the long end extending forwardly. The bar 31' may then he slid outwardly, as is shown in Figs. 1 and 2, and the foot lever 26 released, whereb the wire bending arms 12 are swung to t eir normal position by the action of the springs 30.

Thetable is provided with a forward extension 41 at one end, pivoted to which is'an arm 42. The outer end of the arm carrles a hook forming device, comprising a bushin 43, loosely confined upon which is a ro ler sleeve 44. A washer 45 is placed on top of the bushing to prevent upward displacement of the sleeve. A pin 46 passes thru a lever 47 and the said washer, and

is screwed into the bushing. One end of the lever has a depending finger 48, while a suitable handle 49 is provided on the other end. As is best shown in Fig. 4, a space is left between the depending finger and the roller sleeve. The arm 42 is of such length as to permit the hook forming device to receive the long end of the wire between the said finger and roller sleeve, when the arm is swung inwardly. As is pointed out in Fig. 5, by moving the lever 47 a quarterturn to the left the wire is bent at {an acute angle to the neck, while a substantial rotation of the lever to the right bends the wire round the roller sleeve and forms a hook. This operation completes the hanger and the same may be easily lifted off the machine, a specimen of a hanger formed by a machine embodying the invention being shown in Fig. 12. After the hanger has been removed from the machine, it is obvious that the arm 42 may be swung to an outward position, as is shown in Fig. 1.

It is pointed out that a machine constructed in accordance with my invention embodies an inexpensive and simplified structure.

The machine includes simple and eflicient mechanism for operating the wire bending arms, as well as means for formin a neck and hook on the hanger, and it wil be seen that garment hangers may be produced expeditiously by such a machine. I

Various changes in the size and arrangement of the different parts, as well as modifications may be made without departing from the spirit of the invention.
