To all whom it may concern.-
.Be it known that we, JOHN F. MEIGS and ROBERT P. STOUT, of South Bethlehem, in the county of Northampton, and in the State of the gun; Fig. 4, a longitudinal section through one of the recoil-controlling mechanisms, and Fig. 5 a cross-section thereof.
Letters of like name and kind refer to like parts in each of the figures.
The object of our invention is to provide a light and compact recoil-controlling mechanism for ordnance; and to this end our invention consists in the mechanism having the features of construction substantially as hereinafter specified.
In the embodiment of our invention selected for illustration a carriage is employed mounted on wheels A and A and axle B, the gun Obeing supported from the axle bytwo frames D and D, secured to the axle at opposite sides of the gun. Extending parallel with the gunaxis at each side of the gun is a tube E, that is fastened rigidly to and forms a part of the frame D, each end of the tube being threaded exteriorly and passed through an opening in the frame end, to which latter it is clamped by nuts 6 and e, screwed on the tube on opposite sides of the frame end. The nut on the outer side forms a cap orclosure for the end of the tube. Mounted slidingly upon each tube E is a cylinder F, that has bearing or journal fora gun-trunnion 0. Between said cylinder and the tube is an annular fluid-holding space, the ends of the cylinder being closed in a familiar-way, so as to be fluid-tight, and on the tube E at or near mid-length is an annular enlargement e, that closely tits-the cylinder and constitutes a piston therefor, the tubeE being thus a piston-rod as well as an important part of the gun-supporting frame. Within the tube or piston -rod F at or near midlength is screwed a sleeve Gr, having two oppositely-facing valveseats for two valves H and H, mounted slidably uponabolt or rod I, that is supported by disks K and K at opposite ends'of the sleeve G. A piston L' is in the tubular piston-rod E on each side of the sleeve G, and interposed between the same and the nearer closed end of said. piston is a coiled spring M, that yieldingly holds said piston adjacent to the sleeve end. Channels or passages N and N place the annular space in the cylinder in communication with the space between the two valves, and the disks K and K are perforated to establish communication between the spaces on opposite sides of each. It will be seen that when the gun recoils the cylinders F and F will move with it over the pistons e and a, forcing the liquid from each cylinder into the space between the valves and causingit to move both from their seats and to move the pistons L and L in op posite directions, compressing the springs M and M for producing counter-recoil, to permit which the valves are provided with minute openings for the return of the liquid to, the cylinder. By the utilization of the cylinders as the gun-supports, and the employment of the piston-rods as the slides on which the gun supporting cylinders move and as the housings for the springs and by the arrangement of the springs, there is great gain both in compactness and reduction of weight.
Should it be found desirable to regulate the travel of the gun in recoiling by varying the flow of liquid through the channels N and N, this can be done by applying to the inner end of thepiston a disk 0, having for cooperation with each channel N a slot 0 of dimin ishing cross-section and automatically rotating the disk as the gun and cylinder move longitudinally, so as to present [)Ol'tlOrm of the slot of varying cross-section opposite its ing nut e may be removed, there is placed within the tube a ring form abutment P for the outer end of the spring, which abutment is mounted on the end of-a support Q,-fastened at its otherend to the nearer piston L.
The support Q is jointed telescopically to permit a short expansion of the spring out of the tube.
It is to be understood that we do not restrict the use of'our invention to a wheeled or any other particular type of gun-carriage or mount.
Having thus described our invention, what we claim is 1. The combination of a fluid-holding cylinder, a piston therein, a hollow piston-rod, a passage being provided for the fluid to pass from the cylinder into the said rod, a piston in said rod subjected to pressure from fluid forced through the passage from the fluidholding cylinder, and yielding means to oppose movement of the piston in the rod when it is subjected to pressure from the fluid-holding cylinder, substantially as and for the purpose described.
2. The combination of a fluid-holding cylinder, a piston therein, a hollow piston-rod, and two oppositely-acting pistons in said rod, the fluid-holding cylinder being in communication with a space between the two pistons in the piston-rod. I
3. The combination of a fluid-holding cylinder, a piston therein, a hollow piston-rod, pistons in said rod, movable in directions to ward and from each other, a passage being provided for the fluid to pass from the cylinder to the rod to act on the pistons v therein, and spring mechanism for moving the pistons oppositely to the direction of their movement under the fluid-pressure.
4. The combination of the piston, pistonrod and cylinder of a recoil mechanism, said piston-rod being hollow, a fluid-operated piston in the-rod, and a counter-recoil spring in v the rod acting on said piston, substantially as cylinder, and a spring for each of the pistons that is within the piston-rod, substantially as JOHN F. MEIGS. ROBERT P. STOUT.
