GUN-CARRIAGE FOR REGOILING GUNS.

Neuilly-sur-Seme,

Gun-Carriages for Recoiling Guns, which is fully set forth in the following specification.

This invention has reference to a longrecoil gun carriage or mounting for firing at high angle: of elevation and will be described in connection with the accompanying drawin s, in which,

Y igure -1 is a diagram of the usual a pliances. Figs. 2 and 3 show in sectiona elevation, and in partial plan res ectively, an example of the application of the invention. Fig. 4 is a diagram of a second example of its application.

A gun mounted upon a slideway which permite it to recoil for a long distance (more than a meter) could not readily operate at large angles of elevation (60) if the trunnions were laced in proximity to the center of gravity.

nfact, with such angles it would be necessary,

as shown in Fig. 1, in order that the breech a should not encounter the ground when it reaches a at the end of the recoil, to considerably raise the trunnions c of the gun, which would result in giving the carriage e an inadmissible height. i

In accordance with the present invention, the gun-trunnions c are arranged upon the carriage e considerably -beyond the center of avity oi the system comprised by the gun and the slideway cl. Assuming that this system bd rotates around the axis 0, it is obvious that whatever the angle of elevation may be, the breech a. is able to make a long recoil between the cheeks of the carriage, without encountering the ground, and this without the necessity of raising the trunnions c, and consequently of increasing the height of the gun carriage be 0nd that of existing carriages. Neverthe ess, as the weight of the gun-slideway system b--d is considerable, and owing to the fact that the center of gravity is situated largely in front oi the trunnions c, it would be difiicult to raise the system in elevating the gun, and the invention therefore also com rises means for facilitatin this operation. hese means consist broad y, in an antagonistic or.bal ancmg device formed by a system oi metal Specification of Letters Patent.

springs, or pneumatic or hydropneumatic contrivances, which, are so supported on the gun carriage that they constantly exert ,upon the system constituted by the slideway and the gun, a tractive eiiort tending to raise this system, the said eiiort being applied at a point on the slideway-opposite to the center of gravity of the said system, the trunnions of the gun.

In the form of the invention illustrated by Figs. 2 and 3, the slideway (I may for this purpose be extended in the form of two arms descending below the axis 0 into the space etween the side cheeks of the gun carriage. In a cylinder g carried by the carriage there is arranged between the trunnions c and the wheel-axle h, a spring a, constantly tending to draw the arms f One extremity of this spring bears against v the bottom of the cylinder,

towards the wheel-axle.

and its other extremity acts upon a piston the rod of which is coupled to a cross-piece guided by-rollers m in grooves n of the cheeks of the gun carriage. There are likewise coupled to this crossiece, rods 0 to which chains'p are attache Each of these chains is also fixed to a point on a cam q keyed to a cross-piece 1- carried by the arms f; the said chains being wound upon the surface of the cams. .The gun slideway system on the one hand, and the antagonistic system on the other hand, may be arranged in e ance, about the axis 0 the trunnions c.

The metal spring of the balancing device might. be replaced either 'by a pneumatic sprin or by a pump body containin liquid a rea y under pressure, or place under pressure by means of .a pump. In either case the anta onistic tension should be regulated in sue a manner that its moment relatively to the axis of the trunnions c is at all times equal to the value of the moment of the wei ht of the gun and of the slideway relative y to the said .axis. The balanced on-slideway system being capa le of ready ciange in elevation, any known e evating mechanism for effecting the changes may be employed, for example, a large toothed sector spivoted to one of the trunnions c as center, and meshing with a pinion t carried by a spindle u on the gun carriage and with a pinion '0, carried by a spindle a: on

an arm y of the slidewa d. The balanced system above described is intended to apply, to a case in which the axis of displacement relatively to uilibrium, like. a balof cylinder gis connected over a pul about the gun trunnions is situated behind the center of gravity (the front being the muzzle of the gun). The said system 1s obviously applicable in a similar manner to cases in Wl1lCl'l it is necessary to displace the s stem about an axis otherwise arranged. ig. 4 shows by wayof example the system adapted to be displaced about a point at the muzzle of a gun mounted in a turret in which the embrasure 2 should be reduced to the minimum. In this example, the gun carriage e is assumed to be suspended from the roof of a turret or of a casemate. The said carriage is suspended from the roof by a pivot 1 and a segment 2 and is capable of movement about .thevertical axis of the pivot. The slide-way system bdissup orted on the carriage e by trunnions c and the elevation of the system is effected by elevating mechanism in a manner similar to that already described in connection with that shown in relation to Fig. 2. Inthis arrangement, however, the counterbalancin piston Icy g to cam (1 in order that the slide system may be properly counterbalanced.

The axis of elevation formed by the trun nions c and constituting part. of the slideway (Z is perpendicular to the axis of the pivot 1 and lntersects it. It isat the meeting point of these two axes that the muzzle of the gun is situated, that is to say, the front extremity of the axis of the gun". The embrasure is therefore reduced to the minimum around th afipivot thus defined.

hat I claim and desire to secure by Let the weight of the slideway system inits diffierent angular ositions.

,2. In com ination, a gun carriage, a slideway mountedthereon and having a gun sliding therein, said slideway bein mounted to rock about an axis.beyond t e center of gravity of said slideway system, a pistoncarrying cylinder mounted on said carriage,

a cam on said slideway having a flexible con-- neetion with said piston, said piston acting through said connection on said cam to counterbalance the weight of. theslideway system in its different angular positions.
