UNITED STATES ROBERT MATTHEWS, OF MANCHESTER, ENGLAND.

AMMUNlTlON-HOIST.

SPECIFICATION forming part of Letters Patent No. 670,717, dated March 26, 1901. Application filed November 20, 1900- Serial No. 37,173. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT MATTHEWS, engineer, a subject of the Queen of Great Britain, residing at Openshaw, Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Ammunition-Hoists for Loading Ordnance, of which the following is a specification.

This invention relates to apparatus for loadin g ordnance, and has reference particularly to the hoists by which the ammunitionis conveyed to the gun from themagazine.

In my prior application for United States Patent, filed July 24, 1900, Serial No. 24,684, I described means whereby the bearing of the pulley at the top of the hoist was made movable and so connected to the gun-mounting or some other suitable part that the alteration in the position of the cage, which takes place when the elevation of the gun is altered after the cage has been raised, would only affect the comparatively short portion of the rope adjacent to the said pulley, instead of affecting the entire length of the rope.

It is the object of my present invention to modify the means set forth in said prior specification by substituting for the lever mechanism therein described toothed gearing, as hereinafter explained.

In order that my said invention may be clearly understood and readily carried into practice, I will describe the same more fully with reference to the accompanying drawings, in Which- Figures 1, 2, and 3 are respectively a side elevation, a plan, and a rear elevation of a pair of guns mounted in a rotating turret and provided with my improved apparatus, only so much of the guns and their mountings being shown as is required for a proper understanding of my apparatus. Fig. 4 is an elevation, Fig. 5 a sectional plan, and Fig. 6 a vertical section on the line 1 l of Fig. 4, show ing the improved apparatus separately and on a larger scale.

Like letters of reference indicate similar parts in all the figures.

A A are the guns, and B B the frames in which they recoil.

B is the rotary turret.

C is one of the ammunition-hoisting cages or carriers, and O C are the rails along which such carrier travels.

D is one of the hydraulic cylinders for actuating said cage or carrier, and E is the chain or rope which is acted upon by the ram of the cylinder and connected with the cage or carrier at c after passing around guidepulleys F F. The opposite end of said chain or rope is connected to the cylinder D.

G is the rammer.

f is a segmental slotted guide carried by the vertical framing O to which the rails O are connected. f is a bearing-block which is capable of slidingin said segmental slotted guide and is provided with a lateral axle or stud upon which the uppermost pulley F is rotatably mounted.

' A segmental toothed rack f is fixed to the frame B of the gun, and another segmental toothed rack f is fixed to the framing O Situated between these two racks and gearing therewith are two toothed wheels f and f mounted to revolve together on a stud f, carried by the sliding block f. By these means when the gun, with its frame B, changes its elevation the rack f will be correspondingly shifted and by actuating the pinion f will'cause the pinion f to travel along the fixed rack f and the block f to slide in the guide f. The position of the axle of the pulley F will consequently be likewise changed to the extent required for keeping the cage in alinement with the gun in an analogous manner to that set forth with regard to the arrangement already described in my aforesaid prior specification.

What I claim, and desire to secure by Letters Patent of the United States, is-

In an ammunition-hoist, the combination with an ammunition cage or carrier, a chain or rope passing around guide-pulleys and connected at one end with the cage or carrier, and at the other end to a fixed point, and a hydraulic cylinder and ram for actuating the chain or rope; of a sliding block to which the axle of the uppermost pulley is connected, of a segmental slotted guide disposed approximately concentric with relation to the guntrunnions and carried by a part which does not participate in the movement of elevation or depression of .the gun, of a rotary axle to ICO which the said block is connected, of toothed I my hand, in presence oftvvo subscribing Witwheels carried by said axle, and 0f racks ge'arnesses, this 6th day of November, 1900. ing with said toothed Wheels, one of said racks being carried by the gun-mounting and the ROBERT MATTHEWS 5 other fixed t0 the turret of the gun, substan- Witnesses:

tially as and for the purpose specified. ALBERT EDW. KAY,

In testimony whereof I have hereunto set SAMUEL GUEST.
