In the invention I provide a hopper for end Walls 10 and 11 which. extend. upwardly from andV are supported by thev vertical standards. 50 and 51. These endv walls are connected by the stay rods. 12 and the cross barsor braces 2.7 and 28.. rIhesestay rods 12 projectthrough and serve to .support the guide braces le. and 15.' which project inwardly in a downwardly inclined direction... A shaft 16 is projected through the lower. end of the guide braceY 14. Fiiredly mounted on these shafts 16v and 17 are feed rollers 18 which rotate. inthe. direction indicated by the arrows in Fig. 2L A gear 19-which is driven by a suitable source of power meshes withand is adapted to drive the gear 20.which is fixedly mounted on the shaft 21. Fixedly` mounted on this shaf-t 21 is al gear 22 connected by. the chain belt 23 with the. gear 24 which is iixedly mounted on the shaft 16. A gear 25 is'fixedly mounted on the shaft 16 and meshes with a gear 26 xedly mounted on the shaft 17 so that upon a rotation. ofthe gear 19, the rollers 18 will be rotated in the. direction indicatedjby the arrowsv in Fig. 2. Spaced inwardly from the end walls 10 and 11. are the guide plates 27'.

Mcunted on the cross bar 28- and projected inwardly therefrom is aplate 29 which isv spaced from a plate 'S0' which is mounted' on the-cross bar 27'and projecting inwardly therefrom.. A

.vl slot 68 formed in its upper surface.

facilitate the rolling cf the same onto the rollers 18.

Projecting through and journaled in the side walls 10 and 11 is a shaft 33 on which is iiXedly mounted the gear 34 connected by the chain belt 35 with the gear 36 which is fixedly mounted on the shaft 21. Fixedly mounted on this shaft 33 at spaced intervals are feeding arms or plates 37 each having an arcuate outer edge-33 conforming in contour to the carved surfacev 39 on the prong 46 of the plate 30. A notch 4l is formed in the curved surface 33 of the plate 37 and adjacent this notch so as to follow the same on the plate 37 is a nose or projection 42'. Fixedly mounted on the shaft 33 is a disc 43 carrying the eccentrically mounted stud or roller 44 which is adapted to engage the certain positions of rotation of the shaft 33, the rocker arm 45 which is mounted on the shaft 46 on which is nxedly mounted the feed roller 47 having a peripheral notch 48 formed therein, the construction is such that as the shaft 33 is rotated to a position so that the roller 44 is in a downwardly located position, the roller 47 will be moved to the position shown in Fig. 4 With the peripheral notch 48 aligning with the end of the slot 4l so that a strand of wire 32 may be moved into the notch 48. As the shaft 33 is rotated to put the roller 44 into engagement with the rocker arm 45, the roller 47 will berocked to the position shown in Fig. 2 carrying with it the strand of wire and discharge it into the cutaway portion 49 on the upper end of the surface '39. At the same time the plate' 37 will be revolved into position so that the strand of Wire resting in the cut away portion will have been engaged by the notch 42 and forced downwardly riding in engagement onto the surface 49. As the strand of wire moves out from the cut away portion 49 onto the surface 39, it will be forced into the peripheral notch 41 formed in the surface 38 of the plate 37. A rotatable carrier 52 is shown sectionally fragment in Fig. 1 and sectional in side elevation in Fig. 2 and this carrier 52 is mounted for rotation between the standards and 51.

On the carrier, which is preferably in the form of a drum, are mounted beds 53 which serve to support forming units which operate upon and form the strands of wire 32 into the desired forms. A cam plate 54 is supported on the standard 50 having a groove 54' in which engages a roller 55 projecting outwardly from the end of the arm 56 which is fixed to and rotates outwardly from the shaft 57. Fixedly mounted on the shaft 57 is a bevel gear 58 which meshes with a bevel gear 59 fixedly mounted on the shaft 60 which Yprojects through and is journaled in the bed'53.

A forming arm 61 is fixed on the upper end of the shaft so as to radiate therefrom. A bevel gear 62 is mounted on the shaft 57 to mesh with the bevel gear 63 mounted on the shaft 65 on the upper end of which is iixedly mounted a forming arm 64. At each of these forming arms I have provided on the upper face of the base 53 a block 66 on which is mounted a shaper or forming block 67 having an elongated longitudinal extending The carrier 52 rotates in the direction indicated by the arrow shown in Fig. 2 and the relations of the ,curved prong 40 and the forming block 57 is clearly indicated in Fig. 2. As the carrier 52 rotates to the position that the slot 68 is in alignment with the end of the prong 40, the plate 37 will have rotated to a position so that the notch 41 will align with the slot 68 and thus the strand of wire engaged in the notch 41 will be deposited in the slot 68.

Projecting through lugs 69 is a pin 69 which serves as a pivot for a clamping arm 70, the upper end 71 of which is adapted to move into a position so as to securely clamp the strand of wire in the slot 68. A screw 72 is threaded through the opposite end of the clamparm and adapted to engage the periphery of the roller 73 which is ixedly mounted on the shaft `57 and which is provided on its periphery with a notch 74. As the rotatable carrier moves into the position where the strand of wire passes from the notch 4l into the slot 68 the roller 73 will have movedinto a position so that the screw 72 will ride out of the notch 74 and rock the arm 70 so as to engage the strand of wire with the clamping end 71 and securely 'clamp it in the slot 68 thus holding the Vwire rigidly in position during the forming operation. It is believed obvious that the screw 72 af-.

fords a means of adjusting a clamping pressure. When the roller 47 moves to the position shown in Fig. 2 this roller will serve to close the lower end 0f the slot 3l and prevent passage of any strands of wirev from the slot. When the shaft '33 rotates and this shaft rotates in the direction indicated by the arrow in Fig. 2, farther so that the roller 44 leaves the arm 45 this arm willbe rocked downwardly through the pressure of the spring 45 connected to the arm 45 Whichis connected to and projects outwardly from the pin of shaft 46. With a construction such as described, the wire may be automatically fed from the 'hopper individually and individually placed securely in the slots 68 or the forming blocks and clamped therein. As the carrier 52 moves through its cycle of operation to approach the discharge'position of the finished product, the screw 72 willride into the notch 74 and thus release `the clamping pressure of the arm 70 on the strand of wire inthe slot 68. I thus provide a feeding mechanism, accomplishing the advantages mentioned and one which is entirely automatic in its operation as well as durable in its structure.

' While I have illustrated and described the preferred form of construction of my invention, I do not wish to limit myself to the precise details of the structure shown, but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to `secure by Letters Patent is: Y
