With that device there is constant liability of I may use an alternating current generator f not 55 shown) which may be connected to the drive shaft I3 and having individual synchronous motors driving each of the separate shafts, the motors being operated from the generated source of power.

The coilers 3 4-35 are of the laying type and although the application to the art of drawing wire is new, they are well known to the art of rolling rods, so they require no further description here. Suflicient to say that the'se coilers with their flying arms lay the wire into suitable receptacles for the coil of finished wire, the form of these receptacles being adapted to the requirements for the subsequent handling of the wire.

If the wire is not subjected to further processing and is to be shipped in coils, I provide receptacles comprising an assembly of pins 44-45 arranged in two circles as shown in Figures 2 and 3 upon a spider 46-41. I shall preferably set under each coiler two of these spiders mounted on a rotating member 48 so that the finished coil of wire may be tied up and removed from the full spider while the empty spider is receiving the wire from the continuously rotating coiler'. 'I'hese spiders rotate on centers 49 and are held from rotating while receiving the wire from the coiler by a suitable lock 50. The rotating member 5I is held in place by lock 52; These locks may be released by foot treadles 53-54 and are held in engagements by the springs 55 and 56 respectively.

It may be convenient or desirable in some instances to tip the spiders 41 so I provide a pivot l1 and locking means 58. Upon release of the latch 5I the spider will swing to a plane at right angles to its original .position and from.

there the coil of wire may be removed by the hook GII provided for the purpose, operated by the crane 8 I.

If the wire is subject to further processing, I may use removable spiders 9| set on a rotating .spider 48 provided with suitable means of locking into position 50, all as detailed in Figure 4. The wire may be taken through any subsequent steps of manufacture, such as annealing-on these removable spiders, and they will then act as take-oil' spiders for the drawing operation which may follow.

The housing 23 contains pinch rolls 1I suitably grooved for the gage of wire being drawn which are' held together by compression springs 12. While I have indicated rubber blocks, these springs may be made of coil wire. I provide a guide 1I to aid the wire 20 to enter the wire groove in the pinch rolls 1I. 1I, I provide rolls 14 mounted to revolve at a distance apart to accommodate free movement of the wire so that the wire may pass freely between the rolls. These rollers have a smooth periphery and carry in the middle of their faces shear knives 15. I may employ an anvil shear or its equivalent in the same location and do not wish to be limited to the shearing means.

Between the pinch rolls 1I and the rotating shear 14 I provide a movable guide 15 which is mounted to swing across the face of the rotating shear by means of the solenoids I1-18 or the equivalent mechanism. These solenoids may be operated manually by closing an electric switch or I may automatically actuate them by an electric switch 1l operated by a counter mechanism Il driven by the revolving pinch rolls 1I. so that the solenoids operate to move the Below these rolls energized and the transfer device is set in operation. The Wheel A19 is preferably made of mica with a metallic inset as shown.

When the guide 16 is in the position shown in full lines, it directs the wire into guide pipe 24 leading to its coiler 34; when inthe position -shown in dotted lines it directs the wire into guide pipe 25 leading to its coiler 35. In its movement from one coiler to the other the wire is passed between the shear knives 15. The Width of the knives' and the speed of travel of the guide are so adjusted to the speed of the Wire that contact'of the wire with the knives will occur only once in one revolution of the rolls of the rotating shear.

The pinch rolls are driven through the revolving pulley 45 which is mounted on shaft 62 on which is mounted the gear 63 meshing with gear 64 mounted on shaft 65 with the pinch roll 1I. 51 carrying the cutting mechanism14.

The pinch rolls and rotating shear are driven at synchronous speeds through suitable gear, the entire mechanism being driven from a shaft either mechanically as shown from the wire drawing power line I3 or by a synchronous motor. I prefer to drive through slip friction 80 with the driving pulley at a speed slightly above the synchronous speed as an insurance against slackness in the wire.

I wish it distinctly understood that my apparatus for continuously drawing wire 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 fea- The gear 63 also drives gear 6E on the shaft tures of my invention and I. therefore intend the `coiler to the other without interruption of the progress of the wire, comprising shear knives continuously rotating at the peripheral speed substantially equal to the speed of the Wire, means for transferring the wire from onecoiler to the other and across the path of the shear.
