Description

I Patented Sept. 3, 1940 UNITED STATES PATENT OFFICE WIRE-DRAWING acrame Application August 1,

1 Claim.

through the shaft on which the block is mounted and by which it is rotated. 1

In order to give an understanding of the invention, I have illustrated in the drawing a selected embodiment thereof which will now be described, .after which the novel features will be pointed out in the-appended claim.

In the drawing:

The single figure is a vertical sectional view.

through a'wire-drawing block embodying my invention.

In the drawing, 1 indicates the wire-drawing block which is formed with the usual wire-receiving surface 2 on which the wire 3 is wound after it hasbeen drawn through the die 4. This block I is mounted on and is rotated by a suitable driving shaft 5 which may be operated in any 35 provided with an open-topped lubricant-containing 9 adapted to receive dry lubricant for lubricating the wire and the wire-receiving sur- 1 face ofthe It indicates a stationary plow element located within the chamber 9 and acting member 8 is rotating. 4 I v 1 The-lubricant carrying member 8 is shown. as mounted on a sleeve l'l through which the shaft 5 extends, said sleeve being journaled in the frame 5 not thewire-drawing machine. 1

4 Means are provided for driving the sleeve H at aslowerrate than that at whichthe drum] is driven, and for this purpose, said sleeve is provided with a gear I! which meshes with and is so driven by a driving gear I4. 'Ihe construction and operation of the lubricant containing'member 8 with aslow moving rotatable dry lubricant carto plow the dry lubricant against the drum as the 1939, Serial No. 287,711

is similar to that illustrated in my co-pending application, Serial No. 23

The block I is rovided with an interior chamber l5 and means are provided for.cooling the block by introducing water into the chamber" through the shaft 5, and delivering the water against the walls I6 of the chamber l5.

For this purpose the shaft 5 is a tubular shaft and there is provided a water supply pipe I! which extends through the bore I8 of said shaft 5. This supply pipe is stationary and is cononected to any suitable source of water supply. Said pipe at its upper (and leads into a hollow head member I9 which is provided with one or more laterally extending spray pipes 28 that are con- 1 structed to deliver jets of water against the interior wall l6 of the block.

In the operation of the device, the water supply pipe H and the nozzle pipes 20 serve to deliver water or other cooling liquid against the 'wall l6 of the drum as the latter is rotated, thereby keeping the wire-receiving surface of the drum cool. The supply pipe I] is somewhat smaller than the bore l8 of the tubular shaft Sand the space between the pipe and the, shaft provides 25 a drain outlet through which the water may drain, after ithas performed its cooling function.

The block I is shown as having a removable cap piece 2| which normally closes the upper end be readily removed whenever it is necessary to obtain access to the head l9 and spray pipes 20. I claim; A, A wire-drawing machine comprising a chambered wire-drawing block, a vertical tubular shaft u on which the block is mounted and by which it is rotated, a water supply pipe extending axially through said shaft and into the chamber of the v block, a hollow head secured to said pipe and located within said chamber .and into which the pipe delivers water for cooling the drum, and a plurality of spray pipes extending radially from said head member and arranged to deliver said water against the walls of the chamber in the block at a plurality of points circumferentially thereof, the supply pipe being smaller thanthe interior diameter of the tubular shaft, thereby providing. a passage for water to drain out the chamber through said shaft. v a I enemas n.
