9 Claims.

This invention relates to a winding tool for use in applying concentric layers" of wire to a core, or the underlayers of flexible shafting, wire rope, and the like. More especially, the device has particular application in applying a plurality of wires at a desired pitch upon a core or a previously formed flexible shaft in such a manner that the laying up of the wires may be regulated and smoothly and expeditiously applied.

An object of the invention is to construct the tool whereby the draw or die plate through which the wires forming the layer are drawn may be readily removed and replaced with a plate of difierent die bushing circle as the openings in the draw plate are a factor in controlling the 7 pitch of the convolutions of. the wire as it is wound on the core or previously formed shafting.

A further object of the invention is to provide a winding device through which the core or pre viously formed shaft passes as the wire is laid thereon and to provide means for properly start- 7 ing the winding operation and'thereafter adjusting the device for continuous and rapid winding.

Additional novel features of the device will reveal themselves from a study of the accompanying drawings and specification.

In general, a flexible shaft or wire rope is formed of a plurality of superimposed concentric layers of continuous wire strands. In preparing flexible shafting of this type for use in operating valves, concrete vibrators, portable grinders, driven instrtunentalities and other devices, it is customary to feed the central core of the shafting past a given fixed point and to lay up on the core and succeeding layers of wire as they'are wrapped upon the core a, plurality of suitable gauge wires to form the successive laminations of the shafting. Some of the difficulties of previous devices has been this inability to lay up the wires of a layer in a close, continuousconvolution by reason of the friction created in initially laying on the wires as they pass through the die or draw plate onto the core, and the impossibility of adjusting the device during the winding operation. The angle upon which the wires are laid up as the succeeding layers are wound in starting the winding operation, while overcoming the substantial friction created in the draw plate openings, does not permit the wires to be'laid up smoothly, although this is accomplished after the base core has attained sufficient linear movement or m0: menturn. It is necessary to initially start the laying up at agreater or more acute angle than desired for the normal winding and, therefore. as the diameter of the shaft increases as successive vice during winding takes care of all of these factors and, after adjustment, the tool can be located at the desired position so that during a continuous run the angle will not change.

Specifically, in the drawings, numeral l denotes a horizontal platform for supporting the draw plate and winding tool. The platform is secured to Vertical bars 2 terminating at the height of the platform at one end thereof. "Elongated vertical bars 3 support the platform at the opposite end thereof. These vertical bars 3 are of greater height than the bars 2 for the purpose of forming side-securing means for the removable draw plate which will be hereinafter described. The draw plate 4 rests upon the upper surface of the horizontal platform I and is secured in fixed pos'ition thereon by spaced flanges 5. As shown in the drawings, the draw plate 4 has its entire bottom surface resting on the platform between the spaced flanges 5. The upper edge of the draw plate is fitted in a grooved bar 6 mounted over the upper ends of the vertical bars 3. These bars terminate in a screw threaded portion and carry thumb screws 8.

The removable draw plate itself is provided with a central opening IO of somewhat greater size than the diameter of the shafting which is to be made and this insures-that the core and succeeding layered shafting may pass freely therethrough. A plurality of spaced, concentrically arranged openings are formed in the draw plate 4 through which the wires of the layers of the shafting are passed from a suitable source of supply not shown. The drawings illustrate two concentric circles of openings each of which is fitted with a hardened bushing or guide I i. The smaller diameter circle of spaced bushings is used when thecore isof comparatively small diameter, while the larger diameter circle of openings is used after the diameter of the shafting ha increased.

Also affixed to the platform I is a pair of spaced vertical supporting members IS the upper ends of which are provided with semi-circular cutaway portions for the reception and retention of an internally screw threaded sleeve it. The members I5 are rigidly secured to the platform by means of bolts while it is preferable to mount the sleeve l6 thereon by means of welding. An externally threaded tube -Il is mounted within theinternally threaded sleeve iii with a perforated ;disk-.l.8 secured to the outer send thereof provided with radial spokes b9 for applying rotative movement-to the tube 51. Theopposite .end of the tube '1! adjacent the draw plate is fitted with a hardened bushing 23, having a rounded outer iedgegfor contact with the wires being laid up on the core-or initially formed cable passing through the device. "It will be observed that when movement is given the spokes E9 the tube 1.1 may ,be relatively adjusted toward or away from the draw plate l and it is this adjustment, together with the contact of the bushing '28 and the particular seriesof openings H through which the wires are *fedthrough'the draw plate, that determines :the angle at which the wires are wound up upon the core. When the core or initially wound cable 21 is :first started through the winding tool the bushing on the tube ,I'!

isqspaced asubstantial distance away from the draw plate to reduce the friction created bythe wirespassingthrough the draw plate and, consequently, the Wires are not wound tightly against each other but are at a somewhat different angle than that which isdesired but this adjustmentpermits the cableto be pulled freely through the device. As soon as substantial linear movement is applied to the core or initially wound shafting, the tube l1 and bushing 2i! areadjust- .ed nearer :to the-draw plate, whereupon the wires are .wound uponthe .core or initially wound shafting in'such a manner that each wire i laid up tight against the succeeding helix.

It is essentialthat the initial and adjusted positioned the tub H be maintained and for this purpose .the'device is providedwith alocking-bariorsecuring the device in adjusted position. Thislocking means comprises a horizontal =spring projected rod 25 mounted in registering openings in the sleeve supporting members -15. Agpinidcarrying a washerf ll and having a concentrically/arranged spring .28 hearing against one -,of the sleeve supporting members normally projects the rod 2.5 outwardly. When so projected, one of the plurality of concentricallyaarrarrged-qpening-s 2:? in disk i8. is brought into gregistry with -,the ,outer end of the rod and the resulting en agement holds the disk in fixed position. The opposite end of the rod 25 carries a transverse pin .30 adapted to engage a grooved -;stop;plate :31 when therod is retracted against the tension of :the springEB and turned to vertical position. .This retracted position is maintained while the tube H i -beingadjusted wound thereon.

and, after adjustment, the rod is disengaged from the stop 3] and allowed to project into the nearest registering opening 29.

As shown particularly in Fig. 3, the core or initially wound shafting passes through the device from left to right and is pulled therethrough by any suitable machine or mechanism. As the core or initially wound cable 2| passe through the device, a plurality of wires 35 are led through the bushings II in the draw plate and, due to .the rotation applied to the core or initially formed cable 2|, thewires are layered up or The continued linear and rotative movement of the core or initially wound cable carries the same through the device until the end of the-core or initially formed shaft is reached and thereafter the wires 35 are cut and the .free .ends thereof brazed onto the core or initially formed cable. This comprises a complete cycle, after which the wound core is removed from the draw plate and winding tube andagain run through the winding tool forap: plication of a further layer.
