A. A shaft B is operatively'connected to the shaft A by a chain-4 whichis placed upon the sproclzet 3 and'a' sprocket 5, the latter being rigidly mountedupon" the shaft B. A shaft X is operatively connected to the shaft A by a chain 6, and'a shaft is operatively connected to the shaft Bby achain 7, 1 1- p The frame l-"supports a wire container 8 which is adapted to receive wires 9. Discs.

10 having a plurality of recesses 11 therein are mounted upon a sliaft 12 which is car- 'ried by the frame 1. Guides 13 are secured to the wire container 8 and extend a short distance around-the discs 10. A rotation of the discs 10 in the direction of the arrow.

14: will cause the wires 9 to drop one at a time into the recesses 11 and be carried downwardly until they are released by the guides 13. The discs 10 are operatively connected to the shaft B by means of gears As the wires 9 drop from t e discs 10,

they fall upon finger bars 26 and 27 and are moved forwardly. The mechanism formoving the finger bars 26 and 27 is shown in Figures 4 and 5. The. finger bars 26 and 2.7 each have a recess 28 therein. Abar' 29, which is adapted to be received in the recesses 28, is rigidly mounted upon rods 30. The rods 30 are slidably disposed in bearing plates 31 and 32. Arms 33 are pivotally mounted at their upper ends to the rods 30, and at their lower ends to levers 34. The free ends of the levers 34 are rigidly connected, one to each end of a s shaft '35 which carries an arm 36. The

arm 36 is operatively connected to an eccentric 37 by lever 38. The eccentric 37 is operatively connected to the shaft B, and the shaft B is operatively connected to the power shaft M, as shown in Figure 2.

When one of the wires 9 drops upon the fillger bars 26 and 27, the fingers 39 move the wire forward beneath the spring-pressed gripping plates 40 to the position F where the first operation upon the wire takes place. The mechanism used in the,first-operation is shown in Figure 6. The wire 9 upon reachthis takes place, and Figure 0 end to the supporting ing the position is first firmly and then the end 41 is formed into a The means for grippin the wire 9 consists of a plate '42 rigid y mounted at one frame 1. I have removably secured a die 43 to the plate 42. The die has flat lower and'upper surfaces 44,. and the ends thereof are provided with pro- ,jections '45. v

A plate 46 carr ing an integral lug 47 is pivotally mounte at one end to the frame 1. At the free end-of the movable plate 46, I have pivotally mounted an adjustable bar 47 Extending between the free end of the bar 47 and the frame 1 and pivotally sccuredto both is a rod 48, carrying a roller 49. The roller 49 is positioned above the shaft Y and rides upon a cam disc 50.which is mounted. upon the shaft Y. The cam disc 50 has a high portion 51 and a low portion 52. To the shaft Y, I have also mounted an eccentric 53 which is operatively connected to a forming die 54 by a lever 55. The forming die 54 is pivotally mounted upon themovable plate 46.

When the first operation is completed, the wire 9- is released and moved forward by fingers 56 on the fi ger bars 26 and27 to the position S sho n in Figure 1 At osition the wire9 is again grip e and e second operation takes place. he mechanism used in the second operation is shown in Figures 7 and 8. Figure 7 shows the mechanism just .before the operation 8 shows the mechanism as the operation is about finished. A plate 57, carrying a bending die 58 and a forming die; 59,: is rigidly mounted upon the frame 1. A movable plate 60 is postioned below the plate 57 and is pivotally mounted upon the frame 1. The movable platev60 is provided with an inte ral lug 61 havin an inclined surface 62. The free end of tl ie movable plate 60 is operatively connected to one end of the bar 63 by means of a link-64s The free end of the bar 63 is pivoted to the frame. A .cam discv 65 is rigidly mounted upon the shaft X and is in contact with a roller 66 which is mounted upon thebar 63.- The cam disc 65 has a high portion 67 and a low portion 68.

The shaft X also carries a cam 69 which is in engagement with a roller 70. Theroller 70 is rotatably mounted at one end of a lever 71 which is pivotally mounted near its center to the frame 1 and at its free end to a rod 72. A rod 73, connected at one end to the rod 72 and at the opposite end to astatipnary bar 74, is pivotally connected near its center to the bending die 58. The bending die 58 is guided in its movement by tongued blocks 7 5 which proect into the slots 76 in the walls of the die. he bending "die 58 is normally held upwardly by a spring 71.

.98, respectively.

- wardly,

In front of the disc 65 and if the shaft X is mounted an eccentric 76 hi is operatively connected to the forming die 59 bymeans of a link 77. As the eccentric is moved downwardly, the forming die 59 is drawn downwardly about its ivot until the center pin 79 is in a ignment with the center of a forming block 8.0.

Then by a further movement, a roller 81 upon the. forming die 59- will roll for a short distance around the block 80.

Upon the completion of the second operation, the wire 9 is released, caught by tongue 82, \and moved forwardly to the osition T, as shownin Figures 1 and 9. he wire 9 is then gripped between a forming die 83 and a movable plate 84. One end of the plate 84 is pivoted at 85 to the frame 1 and the other end, havin an'elongated slot 85 therein, is movably lield by a bolt 86. ,A bar 87 is pivotally connected atone end to the plate 84 and carries a roller 88 at the other end. The bar 87 is held against sideward movement by a rod 89. A cam '90 is fixed to the shaft B,.and is in registration with the roller 88. The cam 90 has a high portion and a low portion. When the high portion strikes the plate 84 is raised, forcing the wire 9 against dthe bottom 91 of the forming die 83.

The movable plate 83 is provided with arms 92 and 92' which are pivotally mount ed thereupon. fixed to the shafts A and B, respectively. Bars 94 and 94 operatively' connect the arms 92 and 92 to the eccentrics 93 and The eccentric 93 will rotate at the same speed that the eccentric 93 is' rotated, thus simultaneously raising and lowering the arms 92 and 92'. As the arms are raised, the integral flanges 94 and 94' catch the free ends of the wire 9 and force them upwardly. of the wire 9 passes between the springpressed guide 96 and is forced into the dotted line position shown in Figure 9. As the other end of the wire is brought-up- The head portion it is forced away from the frame roller 88, the

Eccentrics' 93 and '93- are 1 by cammed blocks 97 and 98. The hooked I portion 42 is forced beyond. the neck 99 and becomes hooked thereon when the wire is released. A spring-actuated lever 100 is a positive means for returning the ends of the wire 9 into hooked position, if the tension of the wire should not do so. q

As the arms 92 and 92 are bcingreturned to their lower position, a cam 101, which is carried by the shaft A, strikes a roller 102 i and forces it upwardly. The roller 102 is operatively connected to a plunger 103, and

forced upwardly, taking with the plunger is it a vertical die 104. 5 The vertical die 104 is held in this position until a horizontal die 105 is forced outwardly by a cam-106, see Figure 1, thus pressing the hook'portion 42 about the neck 99. The garment hanger is now completed. By further movement of 'the mechanism, the plate 84 releases the ban er, the fingers 107 on the finger bars 27 catc 1 the lower portion of the hanger and force it free from the device as a cam 108 strikes a plunger-109 and forces the upper portion of the hanger free from the de'vice.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The wires 9 are fed into the container 8, taken one at a time, and dropped upon the finger bars 26 and 27. As the finger bars move forwardly, the fingers 39 catch the wire and move it into the position F. At this position, the wire is gripped between the lug 47 and the die 43. The forming die 54 is then actuated, thus forcing the end 42 of the wire 9 upwardly about the projection 45, and into the shape of a hook.

As the first wire is being released from the first operation, the finger plates 26 and 27 move backwardly, receive a second wire, and as the finger bars are again moved forwardly, the fingers 56 carry the first wire to the position S as the? fingers 39 carry the second wire to the position F. As the second wire is having the first operation, the

ing die 59. is then actuated, thus forcing the' end of the wire 9 about the block 80.

When the dies 58 and 59 return to their normalposition and the first wire is released from the second operation, the second wire is released from the first operation and the finger bars 26 and 27 have moved to the rear of the device for a third wire. As the fingers 39 move the third wire to the position F, the fingers 56 move the second wire to the position S and the fingers 82 move the first wire to the position T. As the third wire is havingits first operation, and the second wire is having its second opera-- tion, the first wire is having its third operation. The center portion of the first wire is rigidly held between the movable plate 84- and the bottom 91 of the die 83. The flanges 94 and 94 on the arms 92 and 92' engage with the free ends of the wire, and force them to conform -to the die 83. The hook portion 42 catches againstthe neck 99 and is firmly clamped in place by the ver tical die 104 and the horizontal die 105.

Upon the completion. of the third operation, the finger bars return to the rear of the device for a fourth wire. The first, second, and third wires are released at this time. As the fourth wire is caught by the fingers 39 and brought forwardly to the position- F, the third wire is caught by the. fingers 56 and brought forwardly to the position S, the second wire is caught by the fingers 82 and brought forwardly to the position T, and the first wire is engaged at its bottom portion by the fingers 107, and at the top by the plunger 109, and freed from'tho device.

It will be observed that the feeding meclianism, the mechanism used in the first, sec- 80 ond, and third operations, and the mecha- -nism for operating the finger bars 26 and 27. are all operatively connected to the main or power shaft M.
