Beit known that l1,11 EAN BAPTISTE GUs'rAvE ADOLPHE CANET, engineer, a citizen of lthe Republic of France,` and a resident of Paris, France, have invented certain new and useful Improvements` in and Relating to Gun-Mountings, (forrwhichE-Ifh-ave `,obtained a patent in France, No. 216,937, dated October 23, 1891,) of which the following is a specification, reference beingfhadto the accompanying draw-l ings. v
'lhis invention relates to gun mountings. According toene" construction, a sleeve in which the gunslidesis formed on or attached to side frames or cheeks which are provided with trunnions, and in the said sleeve or attached thereto on thelower side thereof is provided a single hydraulic brake cylinder the piston rod of which is attached to a hoop or. ring fixed on the gun. The said hoop or ring slides onthe said side framesor cheeks duringthe recoil and running out' of the gun. In a slghtlyniodiied form of construction, an additional sleeve through which the gun' slides 4 and hascast on it or attached to it a hydraulic is formed on the side frames, and the brake cylinders are arranged at the sides of the gun.
The said invention alsocomprises the p'rovision of subsidiary hydraulic cylinders for running the gun in and out when desired without firing, and also a novel recuperator in combination with the said sleeve, hoop or ring, .and side frames.
In'the accompanying drawings, Figure 1 is a vertical central section of the recuperator portion of the gun.

VLike letters denote corresponding parts throughoutthefdrawings.
Referring'to Figs. 1 to 6, A is the gun; B is a-sleeve through which the gun can slide;
0,0 areside frames cast with or Iixed to the sleeve BgfC C are the trunnions formed on or D, Fig. 4, representsa'portionof, the carriage. E is a hoop or ring-fixed t0 the gun and adapted to slide on the's'ifde `frames C.
ThevsleeyefB is made in one or several parts,
brake cylinder Fbelow the gun. The piston rod F of: this cylinder is attached at its forward extremity by a collar f Figs. 1 and 4 to a projection E on the hoop or ring E which is suitabiy secured to the exterior surface of the gun'. V,In the construction shown in Figs. 1,'2 andg4`the hoop E is secured between projections'Ar formed on the gun and a hoop e constructed in halves and held by means of a ring e2 in arece'ss e' formed in the gun. The projections A constitute an interrupted collar on the gun. The hoop E is made with parts thatproject into and fit in the interruptions of the said collar and thus prevent the gun from turning in the hoop during the recoil. The said ring may be otherwise secured to the gun, for example, it may be placed while hot upon the gun and shrunk into its place thereon. l
The side `frames C, C serve as slides along which the hoop E, which issuitably recessed or grooved at ei'c Fig. 4 for the purpose, moves in its recoiland return. These side frames may or may not be braced by suitable trunnions and may be provided' at the rear with stops or buffers to diminish the shock of recoil. A stop C2 is fixed in the forward end IOO ward'rnovement of the gun.
The hydraulic brake employed in this mounting, is furnished with a ,taper rod F2 arranged to enter acentral aperture F3 in the piston for the purpose of regulating in a well lnown manner the area of the opening through which the liquid, displaced by the entranceinto the cylinder of the piston rod F', flows fromone to the other side of the piston during the recoil. The liquid so displaced operates to force outward the loose head F4 of the brake cylinder yand thereby compresses a spring recuperator which serves to run out the gun at the end of 'the recoil. The recuperator consists of springs G G G G', threaded upon rodsH. The springs-G G bear at their rear ends against the front of the head F4 and at' their Aforward ends vagainst nuts H screwed on the rods H. The springs G G bear at their-forward ends against a flange F5 of the brake cylinder and at their rear ends against shoulders i12-formed on the rods H. H3 is a piece secured to the brake cylinder and forming a guide for the rear ends of the rods H. A
A spring loaded valve F6 which is mounted on the piston rod in front of the piston is raised from its seat by the pressure of the liquid flowing through orifices F7 F7 from one to the other side of the piston during the recoil, and returns to its seat when the recoil is finished thus preventing the return of the liquid and maintaining the gun run in until a return thoroughfare is opened. This valve is in some cases perforated with small bypass orifices f6 which allow-of the slow return of eachf side frame or beam to limit the `forof the liquid and thus permit of the immedi ate commencement of the running out of the gun under the action of the recuperator while however moderating the' speed of the running out.
F8 Fig. l is a passage formed in the wall of the brake cylinder and communicating with the ends of the said cylinder on opposite sides of the piston. The area of lopening of this passage can be regulated or the said passage can be closed entirely by means of an adjustable valve composed of a conical screw plug F" which is adapted to be screwed down upon a seat formed in the metal around the passage. By means of the adjustable screw-valve controlling the passage or thorough fare FS the speed of running out can be regulated at will. Orilicesffare made leading into the said passage F8 on opposite sides of the screwdown valve F into which orifices can be inserted the delivery pipe of a pump in case it should be necessary or desirable to use the same for running the gun in and out of battery. When a pumpis not in use for the purpose the said orifices are closed by screw plugs fzfz. The action of the brake cylinder is well understood and need not be further explained here.
The mounting illustrated in Figs. 7 to l2 possesses the same general characteristics as those above described, that is to say, it comprises the rear sleeve B to which are attached the side frames, beams, or checks C, C but there is a difference in respect of the arrangement of the brake cylinders F of which according to this part of the invention there are two placed one on each side of the sleeve B. n this mounting is also provided a forward sleeve B infront of the fixed hoop or ring E. The trunnions are formed on the sleeve B and project through and fit into openings C3 provided in the side frames C. The sleeve B is fitted with bushes B2 B2 which can be re- 'meved when Worn and replaced by new ones. The side frames C are made with central openings which form guides for the hoop or ring E that is constructed to slide therein during the recoil and running out of the gun.
The construction of the brake cylinders is case the excess of liquid expelled by the entrance of the piston rods into the brake cylinders, passes out through pipes F10 which communicate with a valve box J containing a spring loaded non-return valve E6 and raises said outlet valve and passes along a pipe c to a reservoir of compressed gas or air K Fig. 13 or into an air recuperatorunder spring pressure. The said air or gas recuperator is constructed of one or more hollow cylinders K connected to each other at both ends bypipes K2, K3 and provided with pistons K4 above which is the air or gas under pressure. The y liquid enters the recuperator at the lower end below the said pistons which are covered by a slight depth of liquid. rlhis arrangement effectively' prevents the escape of the air or gas under pressure in the recuperator.
A passage Jf Fig. 8 fitted with a plug vor screwdown stopper J2 is provided to permit the liquid to reenter the brake cylinders and force the gun back into battery when required.
A special device is shown in Figs. 8 and l0 which allows the gun to be moved into and out of battery at will. This device comprises two or more hydraulic cylinders L mounted or formed on the sleeve B and provided with pistons L the rods L2 of which are normally or under ordinary conditions locked by pins L3 passing through the same and through a piece L4 fixed to the cylinder. The forward end Lof each piston rod is adapted to be coupled by a pin for example to a stud LG or the like fixed in the hoop or ring E. For running the gun in, it will be sufficient to disengage the pins L3, move the piston rods L2 forward, connect the said rods to the studs L6 and then inject liquid under pressure in front of thev pistons L of Vsaid hydraulic cylinders. The mounting shown in Figs. 14 to 17 is also characterized by substantially the same features in respect of the rear sleeve and the side frames or cheeks furnished with trunnions. The said frames or cheeks however in this modification are united at their forward ends by a piece B cast on or otherwise attached thereto and forming with a cover or cap ll3 a sleeve similar to that above described, but in this' IDO IIO
