T0 0. whom, it may calf/earn:

Be it known that we, LoUIs R. R. DE PLAN UE and JAMES BIGGERSTAFF, citizens of the United States, and residents of Yonkers, county of Westchester, and State of New York, have invented certain new-and useful improvements in Frames for Winding Armature-Coils, of which the cation. a

This invention relates to frames for windmg armature coils or inductors, and has for its object to provide a frame of the half-barrel type by means of which several coils can be wound at once and even in less time than was required for winding one coil heretofore, thus being a means of winding armaturecoils at a considerable savingin time, labor,

following is a'specifiand money to the manufacturer.

To accomplish this object, our invention consists of a frame for winding armaturecoils comprising amember having a plurality of steps and a second member detachable from the first member for permitting the coils the frame.

The invention consists, further, in arrangwires arranged on-each of saidcoils in position; and the invention consists, further, of certain novel features and combination of parts which will be more fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a front elevation of our improved frame for winding armature-coils. Fig. 2 is a top View of the same Fig. 3,-an inside view of the detachable member. Fig. 4 is an inside view of the member, showing the steps for properly placing the wire; Fig. 5, a transverse section of Fig. 1, taken on line 5 5 of Fig. l, but showing the Wires in position; and Fig. 6 is a plan View of an end portion of Fig. 5, also showing the wiresin position ready for removal from the frame.

Similar letters of reference indicate corresponding parts in the different figures of the drawings.

Referring to the drawings, A represents a ame for winding armature-coils, consisting of a member B and a member 0. The member B consists of a portion D, having a plurality of steps D, all of the same width, as

, shown in Figs. 2 and 5, and a shoulder portion E, somewhat larger in size than the step portion D, the function of which is to prevent the wires forming the coils from sliding off the step portion D. The step has a longitudinal section corresponding to the shape of the coil desired to be wound, as shown in Fig. 4, and portion D is provided with pins (i, one at the end of each step, so as to prevent the wires from slipping off the steps. The shoulder portion E is provided with a'small recess e and pin 2 for holding the end of the wire at the commencement of the winding operation. The members B and Care each provided with a central hole H, through which'the shaft I of the winding-machine passes, and with smaller holes L and slots M, through which a needle and thread passes, by means of which the wires when their winding in the frame is completed are temporarily tied up. The member C is provided with pins N, which register with holes N of the member B when the members are assembled. When so assembled the member C has the same function as the shoulder portion E, so that when the wires are wound around the frame the long straight portion of each coil is formed between and by the two rear parts B and C of the shoulder portions,'and the curved portion of each coil is formed between the front parts B and C and by the step portion D, as shown clearly in Fig. 5. The width of the individual steps and the width of the space between the shoulder portions where they are nearest together vary proportionately to the number of coils to be wound fora given thickness of wire.

In the drawings the simultaneous winding of four coils is shown, and Fig. 5 shows the width of the smallest space between the shoulder portions and the width of one individual step to be the same. With this width a larger number of coils could be wound if the thickness of the wire be decreased, or if a larger diameter of wire than that shown in the drawings be desired then the width of the individual steps and the width of the smallest space between the shoulder portions, in the particular form embodied in the drawings the space between the rear parts of the shoulder portions, would have to be increased correspondingly, the number of coils times the diameter of the wire giving the width of an individual step and of the smallest space between the shoulder portions.

The mode of operation of our improved frame is as follows: With the frame Asecured to the shaft I the ends of four wires, if four coils are desired to be wound, or five ends'in case of five coils, are entwined around the pin a and placed in groove 6 and then each wire arranged on a separate step on the step portion D, being properly held in position thereon by the pins d. The frame is then turned several times, depending on the number of turns desired for each coil, four in the case shown in Fig. 5 of the drawings. At the end of the fourth turn the frame A is brought to a standstill, whereupon a threaded needle is passed through the holes L. The thread or cord is cut to proper size, the ends passed through the slots M and used to tie the long end of the coils together in a bundle. Suitable pieces m of cardboard or other suitable stiff material are used for separating the wires of one coil from those of another, as shown in Figs. 5 and 6. The member C is then removed from the member B and the wire bundle forming the various coils removed from member B, and more particularly from the step portion D. The frame is then ready for use for a second winding. The thread or cord at is then cut out and each coil, now separated by the pieces m, is taken up from the rest,

properly clamped or tied in a manner well.

known, and then passed on for the purpose of insulating the same, preparatory to assembling on the armature.

By our improved frame any number of coils can be wound by power in the same time in which heretofore one coil was wound, the number of coils capable of being wound at one winding depending on the width of each individual step, the width of the smallest space between the shoulder portions and the thickness of the wire.

We do not wish to limit ourselves to the embodiment of the invention shown in the drawings, and more particularly we do not wish to limit ourselves to the form of the steps shown in the drawings, a groove of the same depth as the width of one of the steps being the equivalent in function to the steps in the drawings. So, many other modifications may be made without departing from the spirit of our invention, to which we believe ourselves entitled to a broad construction, for the reason that we were the first to winding simultaneously of several coils. Nor do we wish to be limited to the particular form of shoulder portions shown, as others performing the same funtion may be used without departing from the spirit of our invention.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. A frame for winding armature-coils, comprising a member provided with a plurality of steps anda shoulder portion, and a detachable member adapted to act as a shoulder portion when assembled with the first member, the width ofeach individual step and the width of the least space between the shoulder portions, varying proportionately to the number of coils to be wound for a given thickness of wire.

2. A frame for winding armaturecoils, comprising a member having a portion provided with a plurality of steps and a shoulder portion, pins arranged on each of said steps, and a detachable member adapted to actas a shoulder portion when assembled with the first member.

3. A frame for winding armature-coils, comprising a member having a portion pro vided with a plurality of steps and a shoulder portion, a detachable member adapted to act as a shoulder portion when assembled with the first member, and registering holes and slots in communication therewith, in each of said members.

4. A frame for winding armature-coils, comprising a member having a portion provided with a plurality of steps and a shoulder portion, a detachable member adapted to act as a shoulder portion when assembled with the first member, holes in one member, pins registering with said holes in the other member, and a shaft-hole passing through both members.

In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
