3y MW M Attnrney Patented July 16, 1935 2,007,975 WORKTABLE, Grafton S. Kennedy, Dayton, Ohio Application August 2 1, 1933, Serial No.,687,635 3 Claims. (01. 86-1) (Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 0. G. 757) The invention described herein may bemanufactured andused by or for the Government for governmental purposes, without the payment to me, of any royalty thereon. i

This invention relates to awork table and more particularly it has reference to an apparatus for breaking down fixed ammunition. V

The purpose of the invention is to provide a simble and eflicient apparatus for separating connected members. In the apparatus a slidable ex-'- tractor is mounted for pivotedmovementso that the separated member engaged by the extractor will be free to assume an inclined position and pour out its contents.

To these and other ends, the invention consists in the construction, arrangement and combination of elements described hereinafter and pointed -out in the claims forming a part of this specification.

A practical embodiment of the invention is illustrated in the accompanying drawings, where- Fig. 1 is a plan View of the improved work table.

Fig. 2 is a view onthe line 2-2 of Fig. 1 showing a cartridge case separated from a projectile.

Fig. 3 is an end view of the table.

Fig. 4 is a sectional view on the line 4-4 of Fig.1

Referring to the drawings by characters of reference there is shown a table consisting'of legs 5 and a top comprising a frame having sides 6--6 and ends 1-1; 1

A pair of rods 8--8 extending between and connecting the sides fi6 at one end of the frame carry the jaws 9-9 of a vise which is adapted to engage the projectile A of a round of ammunition. A visescrew l0 mounted in one of the sides 6 of the frame acts on one of thejaws 9 in the usual manner.

At the other end of the frame each side carries a rail ll extending inwardly fromthe side. A carriage in the form of a yoke l2, having a groove [3, in each of its arms l4, whereby it is mounted for sliding movement on the rails, is generally disposed horizontally in the plane of the frame. An extractor l5ex'tending across the open end of the yoke is trunnioned by means of pins I 6--l 6 in the arms 14. The extractor is formed with a U-shaped opening H for receiving the cartridge case B of the round of ammunition. The rim b of the cartridge case is adapted to engage the marginal portion IB definingtheopening ll.

Fig. 6 is a sectional view on the-line 6-6 of The base of the yoke I2 is connected to a rack bar l9 by means of a screw bolt 20. The rack bar is slidably mounted in a groove 2! in the corresponding end I of'the frame. The rack bar is reciprocated by means of a pinion 22 fast on a shaft 23 (Fig. 5) The shaft'is journaled in bearings 24 and 25-9-25 respectively carried by

brackets

26 and 27 that are secured to the end it of the frame.- Ahandle 28 is secured to a projecting end of the shaft so that the shaft and pinion may be conveniently rotated.

In operation,the round of ammunition is placed on the work table with the projectile A gripped by the jaws 9 of the vise and the cartridge case B engaged by the extractor l5. The handle 28 is then acted on to rotate the pinion 22 and retractthe rack bar l9 and the yoke l2 carrying the extractor. Since the cartridge case is firmly engaged by the extractorit will be separated from the projectile. As soon as itis free of the projectile, its open end will swing downwardly under the influence of gravity and the contents when in loose form or capable of flowing will be automatically poured into a suitable receptacle. When the cartridge case is empty it-is removed from the extractor. r

During the operation of separating or disconnecting the cartridge case from the projectile the latter, being firmly held by the vise, is in a favorable position to enable its fuse C to be removed by another operator.

I claim: l. A work table comprising a frame, rails extending inwardly from the sides of the frame at one end thereof, a yoke slidably mounted on the rails, a rack connected to the'yoke and guided work holder trunnioned in the carriage and tiltable towards the opening in the frame and a vise carried by the frame in spaced relation to the carriage. r

3. In an apparatus for separating connected members, a support having an opening, a reciprocable carriage mounted on the support, apivoted extractor mounted on the carriage above the opening in the support and adapted to engage one end of one of the members to be separated and means on the support for firmly holding the other one of the members to be separated.
