Patented Apr. 18, 1933 UNITED STATES PATENT OFFICE EDWIN J. MCIL'VRIED, OF CLEVELAND, OHIO, ASSIGNOR, BY ASSIGNMENTS, TO WESTERN ELECTRIC COMPANY, INCORPORATED, OF NEW YORK, N. Y., A. CORPORA" TION OF NEW YORK Application filed April 24,

The present invention relates to the art of wire drawing and particularly to attachments for wire drawing machines, whereby the efliciency and productivity of these ma chin-es may be increased.

In the use of the usual or ordinary type of wire drawing machines, it is frequently necessary to change the machine from one in which the wire is received upon spools to one in which the wire is laid up in open coils. In changing from spooling to coiling, it has been necessary to make extensive alterations in the-delivery end ofthe wire drawing machine, which requires considerable time, and labor, and it is the purpose of the present invention to make the "operation of chan ing over more convenient and expeditious.

The present invention provides for a new and novel arrangement of the delivery end of a wire drawing machine, whereby the op-v erator can change and adapt the machine for I either operation in a comparatively short period and without necessitating the extended shut down of the machine. The invention is shown and described in its preferred form and in which form it can be changed over rapidly and economically.

While the description and drawings are detailed so as to enable the invention to be readily understood by those skilled in the art, it will be appreciated that changes and -modifications may be made therein within the scope of the invention as set out in the claims.

In the drawlngs there IS shown a w1re drawing machine provided with the spooling and coiling apparatus, the machine being shown somewhat diagrammatically, as the details of the drawing machine are no part of the present invention, except as the same may be used in conjunction and combination with the improvement.

' Figure 1 is a plan view of a wire drawing machine, as adapted for the spooling operation, showing the manner in which the'invention is to be applied thereto.

Figure ,2 is a section in the line 2-2 of Figure 1 along the capstan .shaft showing the machine equipped forspooling.

Figure 3 is a similar section showing the.

WIRE DRAWING-v MACHINE 1929. Serial No. 357,754.

machine equipped for the coiling operation, showing the capstan removed and the block in place in the machine.

The wire drawing machine is indicated by the numeral 1. The main or worm shaft of the wire drawing machine is indicated by the numeral 2, by being driven from the motor 3. In addition to driving the drawing rolls, this shaft extends "through the machine and through suitable cliltches and gearing and drives the spool shaft 5 and the spool 6 thereon.

The shaft 2, is provided'with the worm 8 which drives the worm gear 9 on the transverse shaft 10 mounted in the bearings 11 on the machine housing 12. The shaft 10 extends through the housing to provide a driving extension 15. on which is keyed and removably mounted the main or finishing capstan 16.

In spooling the wire the capstan 16 is mounted on the shaft 10 being held in posit1 on by the nut 18. The wire is. given the requisite number of turns about the capstan and is then passed to the spool 6.

To change over to the coiling method, the

upper part of the housing is provided with an opening 20, circular in form, and covered, when not in use by removable plate 21. When the cover is removed a ring 22 is placed over the opening 20, being properly located by means of a flange or rib 23, and held inposiassembled, to mesh with the bevel driving pinion 36 on the shaft 10. When the capstan $3 is removed 1t may be replaced by a collar The operation and advantages of the aption by bolts 24 which also pass throughthe paratus will be readily appreciated. The

' change-over from the spooling to the coiling operation is made possible by removing the capstan 16, and the plate 21, and placing the block assembly in the opening 20,- with the bevel gear 34 in mesh with the bevel gear 36. The change-over is made without disturbing the path of the wire, the receiving point in the block being coincident with the point at which the wire passes on to the capstan.

What is claimed is: 1. In a strand working machine, means to rovide interchangeable finished strand deivery means and finished strand take-up means comprising ahousing, a drive shaft therein, a capstan adapted to be mounted on the shaft for delivering the finished strand, and a winding unit adapted to be driven by the shaft and to be removably mounted on,

the housing as a unit,-with the strand receiving point of the winding unit substantially coincident with the strand receiving point of the capstan and with the plane of rotation of the winding unit substantially perpendicular to .the plane of rotation of the capstan.

2. In a wire drawing machine, means to provide interchangeable finished wlre delivery means and finished wire take-up means comprising a housing, a drive shaft 1' ournaled therein, a capstan adapted to be mounted on the shaft for delivering the finished wire, a drive gear on the shaft, said'finished, wire take-up means removable as a unit and com-' prising a secondary housing, a driven shaft j ournaled in the secondary housing, a gear on the driven shaft, and a drum for laying up the Wire in coil form mounted on the driven shaft within the secondary housing, said secondary housing adapted to be mounted on said first named housing with the gear on said driven shaft meshing with the .drive gear on the first named shaft and with the periphery of the drum substantially coincident with the wire receiving point of the capstan.

3. In a strand working mechanism, interchangeable strand delivery means and strand laying-up means comprising a housing hav-- ing an aperture therein, a shaft extending within said housing, a capstan adapted to be mounted on the shaft external tosaid housing for deliverin the finished strand, a transmission mem er secured to said shaft, said strand laying up means comprising a stationary member adapted to be secured to said housing, a rotatable drum, a second shaft secured to said drum and extending through said stationary member, another transmission member secured to said second shaft and adapted to slidably engage said first mentioned transmisison member, an located between said stationary me ber and said second shaft for preventing movement between said stationary member and said second shaft in a direction parallel to said shaft and permitting rotatable movement between means said stationary member and said second shaft,

and said strand laying-up means positioned over and adapted to cover the aperture in said housing with the periphery of the drum substantially coincident-with the strand re ture therein, a shaft extending within said housing, a capstan adapted to be mounted on the shaft external to said housing for delivering the finished strand, a transmission member secured to said shaft, said strand laying up means comprising a stationary casing, a

rotatable drum located within the casing, a
