DEVICE ‘ Oliver J. Luke, St. Louis, Mo., assignor to Carter Carburetor Corporation, St. Louis, Mo., a cor poration of Delaware Application October 29, 1945, Serial No. 625,281 8 Claims. (Cl. 242-13) I 2 This invention. relates to holding devices for wires or cords which must be held taut during jecting portions of pins l6 and I’! and plate 23 spaced outwardly of the base member. An addi tional wire holding pin 29 projects longitudinally from base I5 and has a sharp edge 29a. In operation, at the start and during the prog such manipulation of the wire or cord as the winding of coils. Coil winding machines, particularly for small motor armatures, are provided with hooks or pins conveniently located to receive a coiled end of the wire being wound and hold the wire taut during manipulation. However, at the end of the Winding, it is necessary for the operator to un wind or pull the wire from the pin or hook and this is difficult where very fine Wire is used. The object of the present invention is to pro vide such a holding element for the end of a wire or cord being manipulated together with means for quickly and conveniently sweeping or casting off the wire from the pin at the end of the winding operation. This object and other more detailed objects ress of the winding, wires 26, 21, and 28 are intermediately looped about pins l6 and I1, thence passed between guides 30 of the winding machine. The extreme end of wire 28 is coiled about pin 29 and edge 29a used to break off excess wire. After the coil is completely wound, the operator strikes actuating plate 23 to move it and push-off plate 22 to the position shown in Fig. 4 which sweeps the wire loops from pins 16 and I1 and also pulls the end of the wire from pin 29. This leaves the ends of the various coils free for at tachment as by soldering to the commutator bars. Since actuator plate 23 is relatively large and the wires may be released from their holding pins hereafter appearing are attained by the device _ simply by striking the push-O?’ member, this oper illustrated in the accompanying drawing in which Fig. 1 is a side view of a coil winding machine embodying a holding device according to the pres ent invention. Fig. 2 is an enlarged perspective view of the ation is much simpler and faster than would be the case where the operator must embrace the ' holding device. small pin and wire loops with his ?ngers to pull them off with the holding pins. - Obviously, the number of holding pins may be varied in accordance with the particular require ments of the winding machine. The invention may be modi?ed in this and other respects as will occur to those skilled in the art and the exclusive Fig. 3 is a longitudinal section of the device. Fig. 4 is a view similar to Fig. 3, but showing the wire pushed o? its holding pins. The coil winder in Fig. 1 comprises a motor 6 30 use of all modi?cations as come within the scope which drives a shaft 1 supported at its outer ex tremity by a journal bearing 8 carried on framing projection 9. Mounted intermediately of the of the appended claims is contemplated. I claim: 1. A wire or cord holding device comprising a shaft is a winding device Ii} for motor armatures, base, a pin projecting therefrom for attachment this device being of known construction. Mount 35 of a wire or cord, and a push-off element slidably ed on the device and carried therewith is the mounted on said pin, said element being actuable holding device ! l to which a wire l2 may be outwardly of said pin to force the cord or Wire attached for holding the wire taut while the shaft is rotated to wind the coil. therefrom. 2. A wire or cord holding device comprising a The holding device, best shown in Figs. 2, 3, 40 base, a pin projecting therefrom for detachably and 4, comprises a base I5 having a pair- of per holding a wire or cord, and a push-01f element manently mounted pins l6 and I‘! projecting lat having a recess slidably receiving said pin, said element having projecting structure actuable to erally therefrom. The base also has a pair of countersunk holes l3 and I9 through which slid move said element outwardly along said pin and ably extend a pair of rods 20 and 2|. A strip or 45 detach a cord or wire therefrom. push-01f element 22 is rigidly secured to the left 3. A wire or cord holding device comprising a base, a pin projecting therefrom for detachably hand extremities of rods 20 and 2| and has a holding a wire or cord loop, and a push-off ele pair of holes slidably receiving pins l6 and I1. An actuator plate 23 is rigidly attached to the " ment comprising a part separate from said base opposite ends of rods 20 and 2|. Coiled springs 50 and slidable on said pin and actuable outwardly 24 and 25 are compressed between the counter thereof to detach the wire or cord loop there sunk portions of recesses 18 and P9 in the base from. and plate 23 and normally maintain the push-01f 4. A wire or cord holding device comprising a device in the position shown in Fig. 3 with plate base, a pin projecting therefrom for detachably element 22 at the inner extremities of the pro 55 holding a wire or cord loop, a push-oil‘ element 2,412,591 3 4 '7. A device for detachably holding the end of a comprising a part separate from said base but wire or cord during manipulation of the wire or slidable on and actuable outwardly of said pin cord comprising a base, a pin projecting there to detach a wire or cord 100p therefrom, and from about which the wire or cord may be wound, a push-off member comprising a part having a hole slidable on said pin and a guiding element slidable in said base member, and spring means means yieldingly maintaining said part inwardly of the wire or cord loop receiving portion of said pin. 5. A wire or cord holding device comprising a normally maintaining said push-off member with base, a pin projecting therefrom for detachably receiving a wire or cord loop, and a push-off mem said part spaced inwardly of the wire or cord said parts slidable in said base, one of said parts operator to cause said piece to sweep said wire or cord from said pin. ber comprising a pair of parts on opposite sidesvw' receiving part of said pin and said element pro jecting beyond said base for actuation by the of said base, and a connecting element between embracing and being slidable along said pin and the other part being disposed for manual actua tion to sweep a Wire or cord loop from said pin. 6. A device as described in claim 5 further in 8. A device as described in claim 7 in which - said push-off member has a pair of elements slid able through said base, said elements being con nected by a striker plate on the opposite side of said base from said element.
