On the outside periphery of this the line 4-4, Figure 2. hub I provide a cam slot 38. Adapted to travel 45 Figures 5, 6, 'I, 8 and 9 are diagrammatic views, in these slots 38, I provide a plurality of rollers 39, showing the relative position of the two sets of one for each finger 25, mounted on studs Ml to fingers during the completion of a coil and its the oscillating ring 4|.

Figure 11 is a detail of the cam operated valve The movement of the ring 4| is through the controlling the air cylinder operating the set of air cylinder 42, the piston of which is controlled by a valve 46, (see Figure 10) which is timed by the cam 41 keyed to shaft 48.

In the construction shown I provide a roller 49 mounted on an oscillating lever 50 pivoted at 5|. This roller travels on the face of the cam 47 and rocks the lever 52 and valve handle 53 opening and closing the valve 46.

In Figure 11 I show a similar cam operated valve 54 which is controlled by cam 55 also mounted on shaft 48.

Cams

47 and 55 are keyed to shaft 48 which is rotated a definite fraction of one revolution by movement of lever 92. connects to shaft 48 through the pawl 93 and ratchet wheel 94. The movement of lever 92 is between two definite positions 92 and 92'. This movement is determined by stop carried by lever 92 engaging notches 96-and 91 in quadrant 98. Paw] 99 prevents shaft 48 from rotating in a reverse direction.

In operation, the operator moves lever 92 from its position 92 to position 92'. As a result, shaft 48 and cams 4'! and 55 are rotated a definite fraction of a revolution so that earns 41 and 55 operate

valves

46 and 54 in proper sequence. For the next step of the cycle, operator withdraws lever from 92' to 92, and advances it again to 92.

Cam 4'1 controls the opening of valve 46 which is piped to cylinder 42 and cam 55 controls the opening of valve 54 which is piped to cylinder 6'! so that one complete rotation of the shaft 48 in definite intermittent movements causes the cylinders to actuate the fingers and perform the cycle shown in detail in Figures 5, 6, 7, 8 and 9. The cam 4'! controls the valve 46 which actuates cylinder 42 which moves the ring 4| which in turn moves the fingers 41 to and from the engagement with the drum 28 while cam 55 controls the valve 54 which operates cylinder 6'! to move fingers 51 up and down.

During the time the fingers 25 are withdrawn from the drum 29, it is held against rotation by a plurality of fingers 51 which move longitudinally with respect to the vertical axis of the drum and in the upper position engage slots 58 in the drum 2D. In the arrangement shown these fingers 5'! are attached to a plunger 59. The plunger is mounted for vertical movement in guides 60 and raised and lowered by the motion of the lever 6! pivoted at 62. In the arrangement as illustrated the lever Si is provided with a slot 63 in which a roller or stud 64 moves. This stud is attached to a rotating disk 65 and is revolved through a train of gears 66 by the reciprocal movement of the piston in the air cylinder 61 converted by the pawl and ratchet 68.

This cylinder Bl is controlled by the valve 54 herebefore described.- When the coil is to be removed the piston head 69 picks up the stripper plate 70 guided by guide pins H and raises it to the position shown in Figure 7 so that the coil may then rest on the plate 10, upon the withdrawal of the fingers 25 as shown. The plate 10 is then withdrawn into position shown in Figures 8 and 9 while the fingers 25 immediately return to the original position as shown ready to receive the loops of Wire of the next coil.

After the fingers 25 return to their normal position shown in Figure 9 the plunger 59 continues downward to position to that shown in Figure 5 leaving the machine clear for the removal of the coil after manually severing the strand of wire.

From the above description it will be readily understood that the movements of the

fingers

25 and 51 are interlocked through the control of the cylinders by the cams 47 and 55'mounted Lever '92- with proper relation to each other on shaft 48 and actuated by lever mechanism 56.

While I have shown a pipe type of flyer I may use any of the standard types of flyers in which the rod or wire may be led around sheaves or pins instead of through the pipe 22 as shown. My invention is supporting a spindle from a rotary fiyer of any type and the mounting of a drum upon the spindle in such a way that the coil of wire may be removed without stopping the machine or the continuous feed of the wire.

In the mounting of my spindle 2| from the flyer 22'- I show a balancing arm '13 of similar construction to the fiyer tube 22 which is provided to give dynamic balance to the rapidly revolving part. From the fiyer tube 22 and this arm 13 I suspend two disks 14' and 15 to which the spindle 2| is securely fastened so that it revolves with the rotating flyer.

While I' have shown the actuating and interlocking mechanism in its preferred form for simplicity of operation, I do not wish to limit myself to that specific means for operating the two sets of fingers to and from engagement with the drum. It will be readily understood that I may employ an electric system of operation through motor driven shafts and/0r solenoids interlocked by interlocked switches instead of the air cylinders, or I may directly connect two sets of fingers by mechanical transmission. such as shafts, gears or cams, as is well known to the art of machine design.

I wish it distinctly understood that my coil winder herein described and illustrated is in the form in which I desire to construct it and that changes or variations may be made as may be convenient or desirable without departing from the salient features of my invention and I therefore intend the following claims to cover such modifications as naturally fall within the lines of my invention.

I claim:

1. An apparatus for continuously forming wire and/or rods into coils, comprising a rotating flyer to form the wire and/or rod into a coil, a drum loosely mounted in relation thereto to receive the coil, two sets of fingers mounted for movement to and from the drum, means carried by the drum for engagement by the fingers to hold the drum against rotation, means to control the relative motion of the fingers to permit the removal of the coil without movement of the drum.

2. An apparatus for continuously forming wire and/or rods into coils, comprising in combination, a rotating fiyer, a stationary drum suspended therefrom, two sets of fingers mounted for movement to and from the drum to alternately engage and disengage the drum, means to control the movement of these fingers in sequence whereby a coil laid upon the drum by the rotating fiyer can be removed from the drum without rotating the drum.

3. The device of claim 2 with the addition of means to interlock the fingers to secure proper sequence of movements.

4. An apparatus for continuously forming wire and/or rods into coils, comprising a rotating fiyer, a drum loosely mounted in relation thereto to receive the coil, two sets of, fingers mounted for alternate intermittent movement to and from the said drum whereby one set of fingers is always in engagement with the drum to hold the drum against rotation.
