ation of Ohio Falls, Ohio, a corl or Application November 18, 1939, Serial Claims.

This invention relates, as indicated, to wire- C min/ox drawing blocks and the like and more particularly to an improved method and apparatus for cooling such blocks and the wire wrapped thereon.

As wire is drawn through a die, it becomes highly heated and if the wire passes through successive dies without being cooled therebetween, such heating becomes excessive with resultant injury to the wire. This fact has long been recognized by those skilled in theart and various cooling means suggested to overcome the problem. That most generally accepted has been some form of water spray applied to the interiorsurface of the block or drum thus the drum and the wire wrapped cooling both thereon. Various disadvantages 'consequent'upon the employment of this cooling means soon became apparent, .however,"such as the tendency of the water to enter the upper bearings supporting the block and the difficulty due to centrifugal force of removing the water from the block in the desired manner and at the desired rate.

It is, therefore, among the objects of this invention to provide an improved method and apparatus for cooling wire-drawing blocks.

Another object is to provide apparatus of the above-described type whereby the flow of a liquid cooling stream may be under positive control and contact with bearings and the like avoided.

A still further object is to provide a block in which both air and water are employed as cooling mediums.

Other objects of this invention will appear as the description proceeds.

To the accomplishment of the foregoing and related ends, said invention, then consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detail certain means and one mode of carrying out the invention, such disclosed means and mode illustrating, however, but one of various ways in which the principle of the invention may be used. In said annexed drawinga- Fig. 1 is an elevational View in cross section of my new block showing a portionof the driving mechanism;

As indicated above, the principle of my invention is adaptable to the various types of wiredrawing blocks, drums and take-up reels commonly employed, whether they be single or double-decked, intermediate on a continuous bench, or the 'drum on which the wire is wound at the end of the operation. Broadly, the idea of cooling such blocks by means of water or air streams is old as taught by Pat. No. 1,723,313 to Tippet dated August 6, 1929, and Pat. No. 1,959,901 to Mclilvried dated March 13, 1934 Referring now more particularly tothe abovedrawings and especially Fig.- 1, one preferred embodiment of my invention may comprise a cylindrical block or drum I about which the wire is wound, mounted on a tubular vertical spindle 2, said spindle being journalled at 7 Said main-frame also serves, as an oil reservoir in which the gears l, B and is driven, turn;

The wire-engaging surface of drum l is bounded'above by flange it and below by sloping flange ll. Press-fitted or otherwise tightly secured within said drum is a complementary inverted cup-like member 62 with a rib l3 spiralling about its exterior which thus forms a spiral passageway it between the walls of said drum 1 and said member l2. Communicating with the upper end of said passageway is a centrally located chamber it in the bottom of which the upper end of tube it is journalled. Thus, member l5 rotates with drum or block i as a single unit about tube it. Said tube is supported at its lower end by bracket ii and connects with a water line l8 by way of valve it.

Close fitted within the upper end of spindle 2 and turning with it is another tube 26, the upper end of which communicates with the inlower end of which debouches into chamber 2i. From a point below where tube 20 is thus fitted .to'spindle 2, the bore of the latter is enlarged as shown, so as to 9, by which shaft 2 wire-winding block adapted to be water cooled block comprising a drum composed of an upper comprising a cylindrical outer drum adapted to and a lower section, radially disposed recesses in be mounted on a spindle, said drum being open .said drum provided to accommodate the legs and at the top, a hollow cylindrical member inside feet of a stripping mechanism and dividing said said drum having a spiral rib about its exterior drum into a plurality of paired upper and lower adapted to form a spiral passageway between chambers, passageways between such upper and said drum and said member when said member lower chambers adjacent the wire-contacting poris fitted in said drum, and a liquid supply source tion of-the block, a passageway within said spincommunicating with such passageway. dle for introducing a cooling liquid to one of said 6.
