GUNCARRIAGE.

SPECIFICATION forming part of Letters Patent No. 378,333, dated February 21, 1888. Application filed May 10, 1887. Serial No. 237,733. (No model.) Patented in England February 10, 1883, No. 756.

To @ZZ whom it may concern:

Be it known that' I, ANDREW NOBLE, of The Elswick Works, in the city of Newcastleupon-Tyne, England, manufacturing engineer, a subject of the Queen of Great Britain, have invented certain new and useful Improvements in Gun-Oarriages, (for which I have received Letters Patent in Great Britain, No. 756, dated February 10, 1883,) of which the following is a specification.

In accordance with my improvements in guns of the class in which recoil is controlled by hydraulic apparatus the gun is carried by its trunnions upon two hydraulic cylinders which are supported upon a slide and travel along the slide when the gun recoils. The recoil is controlled by hydraulic cylinders and pistons. There are passages through the pistons and valves held by springs to close these passages until the pressure within the cylin- .ders (arising from the recoil) is sufficient to force the valves from their seats. The gunslide is inclined, so that after recoil the gun runs out again by gravity, the liquid returning by external passages from one end of the cylinder to the other. There are hand-pumps on these passages, and by working these pumps the gun can be run in without tiring. There are valves by which the pump-passages can be changed from suction to delivery, and vice versa, so that the gun may, when necessary, be run out by the aid of the pumps.

Figure l shows a plan view, and Fig. 2 a side elevation, of a naval gun-carriage arranged, as above described, as a three-pivot carriage and also for the recoil force to be taken up by a pair of recoil-presses, the pistons of which are iitted with spring-loaded valves, and also arranged withvhand-pumps for pumping the gun out or in, as hereinafter described. Figs. 3 and 4 show a plan view and side elevation of another gun-carriage in which the recoil force is similarly taken up by a pair of recoilpresses, the pistons of which are (as in the gun-carriage shown at Figs. 1 and 2) tted with spring-loaded valves. The piston-rods of the recoil-presses are in this arrangement carried through glands at the front ends only of the cylinders and are fixed to brackets on the front ends of the slides.

Fig. 5 is a longitudinal section ot' a cylinder with double piston-rod and spring-loaded valves carried by the piston. Fig. Gis a longitudinal section of a cylinder with single piston-rod and tank above the cylinder. Fig. 7 shows a longitudinal section, on an enlarged scale, of the cylinder, as in Fig. 5, together with the'pump and, valves. Fig. 8 is a section on the line A B of Fig. 7; and Fig. 9 is a section on the line C D ot' Fig. 7, passing through one setof the pumpvalves.

The carriage, as will be seen from Fig. 2, can be pivoted centrally at A, or at aforward point, B, or at an external point by the use of the pivot-bar C and the rollers, on which the carriage trains are, as shown, capable of being set to any required horizontal angle. Each roller is also, as shown, made up of a number of disks capable of turning independently one of the other.

D D are the recoil-presses, one connected to each trunnion of the gun and forming the guncarriage proper. The piston-rod of each press is carried right through the press and is firmly held at each end of the'slide-face. The piston Dl of each press has the spring-loaded recoil valve or valves b arranged within it, as above described.

E E are hand-pumps by which water may be pumped from one end of the presses to the other in either direction desired, so that by them the gun may be pumped either out or in.. The plungers of the pumps can be worked to and fro by handlevers F. The slide-face is inclined so that the gun may return by gravitation immediately on completing its recoil.

Carriages constructed as above described can be trained so as to bring the muzzle of the gun within a broadside port for housing. The carriage is provided with a rear flap for housing or change pivot. When red on the pivot-bars C, there would be a clip fitted to the carriage suiting a clip-rib xed to the deck. The carriage may be change-pivoted from one broadside to another or from one point to another by a suitable arrangement of racers, if desired. A steel screen, G, may, if desired, be mounted at the front of the carriage, as shown.

IOO

fl and d2 are external passages connecting the ends of the cylinder with a valve-box in which a cylindrical slide-valve, e, Works. This valve can be moved by a hand-lever. f and f2 are other passages leading from the valvebox to the pump E.

f is the pump-suction passage, and j? is the delivery-passage.

F is the hand-lever for Working the pump.

The pump may be double-acting, as here shown, or single-acting pumps may be einployed.

The action is as follows: 1When the recoil takes place, the liquid in the cylinder is driven through the passages a in the piston against the resistance of the spring c. After the recoil the gun returns down the inclined slide by gravity. Liquid then passes from the cylinder by the passage d into the box containing the slide-valve e. It issues from the valvebox by the suction-pipe f, lifts the pump- Valves, and so reaches the delivery-pipe f2. The pipe]C2 delivers the liquid into the annular channel around the valve e, and the liquid again reaches the cylinder by the passage d2. If the gun should fail to run out, it can be forced out by Working the pumps. To force the gun in without ring, the valve c is moved over by means of the hand-lever, and the pumps are then Worked.

Vhen, as in Figs. 3, 4.-, and 6, the cylinders are iitted with single pistons, tanks are cast in the carriages above the presses. A passage,

H, passes from the frontend of each tank 1 to the rear end of its cylinder D. This passage H allows Water to pass freely from the rear of the cylinder to the tank. Another passage, J, is formed from the tank to the front end of the cylinder and is iitted With a Valve, J', opening outward from the tank to allow Water to pass from the tank into the rear end of the cylinder.

Having thus described the nature of my invention and the manner of performing the same, I Would have it understood that I claim as my improvements in gun-carriages*- l. The combination, substantially as described, of the gun-slide, the pair of hydraulic cylinders, one on either side of the gun, carrying the gun by its trunnions and moving along the slide, pistons Within the cylinders connected by their rods with the slides, and passages in the pistons by which liquid passes from one end of the cylinders to the other when the gun recoils.

2. rEhe combination, substantially as set forth, of a pair of hydraulic cylinders, one on either side of the gun which they carry, the slide supporting the cylinders and along which they recoil, pistons Within the cylinders connected by their rods with the slide, passages through the pistons, valves iitted to these passages, springs holding the valves to their seats, and the external passages itted with valves and connecting thc ends of the cylinders.

p 3. The combination, substantially as set forth, of a pair of hydraulic cylinders, one on either side of the gun which they carry, a slide along Which the cylinders recoil, pistons within the cylinders connected by their rods With the slide, passages through the pistons, valves fitted to these passages, springs acting upon the valves to hold them to their seats, passages connecting the ends of the cylinders, and pumps connected with these passages.
