r In Great Britain November 4, 1946 internal diameter of which is normally of the order of six inches. Frequently when such a machine is in use throughout the whole of a day, the operator needs to reload the machine with wire perhaps four times a day since the coils become exhausted relatively quickly. The reloading operation at present often takes as much as ten to fifteen minutes since the coil-supporting device usually fitted to such machines is sometimes difhcult of access and is often of a form which necessitates the use of a tool such as a screw driver or wrench partially to dismantle the wire-holding device in order that a new coil of wire may be inserted therein. The device then has to be reassembled.

It will be appreciated that during a days work as much as three-quarters of an hour to one hour may be taken up with reloading the slugging machine with wire. This is clearly undesirable and it is, therefore, an object of the invention to provide an improved coil-supporting reel which shall be so constructed as to facilitate the operation of reloading the machine with wire,.and shall be of capacity to hold a large enough wire coil to reduce the necessary num ber of reloadings per day under average use to a. minimum (preferably to a single loading per day).

To this end and in accordance with a feature of the invention the illustrated reel which is designed to hold a much larger coil of wire than it was possible to use heretofore in connection with machines of the above-mentioned type, has a plurality of arms which are each provided with a coil-receiving member for facilitating the loading of the wire coil thereon and a spring biased coil-sustaining or clamping member which is pivotally mounted onthe arm and man ually movable between a coil-clamping position and a coilreceiving position. In thelatter position the sustaining or clamping member is clear of the receiving member and allows a new coil to be rapidly placed thereon without the 4 Claims. (01. 242-44) necessity of partially dismantling the device or using tools to adjust the position of any parts thereof. The construction of the coil-sustain ing member is such that its spring acts to hold it in either of the two positions above referred to against appropriate stops; for, as the member is moved from one position to the other, the line; of action of the spring is caused to pass from one side of the pivot of the supporting member to the other side thereof.

The features of the invention will now be described in detail in connection with the accompanying drawings and will be pointed'out in the appended claims.

In the drawings: i i Fig. l is a front elevational view ore of the reel illustrated in Fig. 1, without a. wire coil thereon;

Fig. 3 is a side elevational view of a portionof the reel showing a coil-receiving member anda coil-sustaining member in its coil-supporting position;

Fig. 4 is a view similar to Fig. 3 showing thef coil-sustaining member in coil-receiving pos ition; and

Fig. 5 is'a rear elevational view of the parts shown in Fig. 4.

The illustrated reel which shown in Fig 1 as being applied to a slugging machine as above referred to (the machine being indicated by the chainline i0) is arrangedto support arelatively large coil of wire from which wire W is progres-: sively drawn off by the wire feeding devicesof a spider having four arms l6 radially disposed relative to the axis of the pin [4 and secured to a hub it which is rotatable uponthe pivot pin M.

Wire a friction device is provided consistingof a coiled compression spring 20 which surrounds an, end portion of the pin l4.- The spring Zllbearsj atone end against a washer 22 abutting the hub Hi and at the other end against acollar 24 s e cured on the free end of the pin l4. The hub i8 is spaced from the bracket 12 by afspacing sleeve 26 which surrounds the pin 14;

novel reel showing the outline of a slugging machine To prevent unduly free rotation of the reel on the pin M with consequent slackening of the of the members 23.

Each of the arms [6 has secured thereto a coil-receiving member 28 extending substantially at right angles to the longitudinal direction of the arm. The distance between two diametrically opposite members 28 is slightly less than the internal diameter of a coil of wire to be supported by the device and this arrangement facilitates loading of a coil of wire thereon. The internal diameter of the coil of wire may conveniently be some fourteen to sixteen inches. Such loading is further facilitated by the shape These members, as shown in Figs. 2, 3 and 4, have end portions 3i} which curve slightly inward toward the axis of rotation of the reel and these portions .38 serve to guide the wire coil on to the members .28.

For retaining the coil on the'device after the coil has been slipped over the members 28' each arm I6 is provided with a U-shaped coil-sustaining member 32. Each member 32 is pivotally mounted near the end portion of one of its limbs ,on a stud 34 secured in the arm It with which the member 32 is associated, Each member 32 sustaining members 32 from their operative positions to their inoperative positions, lift the new coil of wire on to the coil-receiving members 28 and snap the members 32 back into their operative positions. The wire has then to be threaded into the machine after being passed through the eye 54 in the normal manner.

It'will be appreciated that the operation of loading a new coil of wire into the wire-holding device may be carried out readily and without dismantling any part of the device and without theuse "of a'tool such as a screw driver or a wrench as is often required in reloading wireholdingdevices as at present employed in machines of the abovee'mentioned type.

This fact, together with the fact that the i1- mstracveeevice has sufficient capacity to hold a wire coil" of large diameter, minimizes the amount of time spent in reloading the machine with wire. 7

Having described the invention, what I claim as new and desire to secure by Letters Patent ofthe has a curved free end portion 36 shaped to provide a finger grip so as to facilitate movement of the member by the operator, and a, tail portion 38 which projects beyond the pivot stud 34 and has a pin 40 extending through it. Each pin 40 has end portions of two springs 42 attached thereto. The other end portions of the springs 42 are attached to a pin, 44 secured in the arm 16 on which the member 32 is pivoted. The construction and arrangementis such that the member 32 is readily movable by the operator from an operative position (shown in Fig. 3) in which the member acts to Clamp a coil of wire on the device to an inoperative position (shown in Fig. 4) in which the member is clear of the adjacent coil receiving member 28 and allows a new coil of wire readily to be loaded thereon without ob- ,4

struction. It will be observed that when the member 3 is in its; p ve o la p n p sition the cross piece 460i that member is positiened in rront of the arms l6 and engages yieldingly but firmly the inside convolutions of the coil or. wire and holds the wire coil securely in the device by partly embracing the coil It will also be observed from Figs. 3 and 4 that the relation of the pivot stud 34 for each member 32 and the associated springs 42 is such that the springs serve to, retain the member 32 in either t ope a ve positi n det m e by engagement or the, pin 40 with a stop 48 formed on the arm is, or ino erative p s t on, determined by n gagement of the member 32 with a stop 52 termed on the coil receiving member 28. The line of action of the springs 42 is so arranged for this purpose. that it moves across the, axis of the pivot stnd 3,4, as, the coil sustaining member 32 is moved rgm one position to the other.
