GUN-CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 295,245, dated March 18, 1884.

Application filed September li?, 1893. (No model.) Patented in Belgium March 274. 1883, No. 60,870; in France April 3, 1983, No. 154,638, and inllaly June 10, 1883, XVII, 15,425.

To all whom, it may concern,.-

Beit known that I, HERMANN GRUsoN, of Buchan, near Magdeburg, Prussia, Germany, hareinvented certain new and useful Improvements in and relating to GiurCarriages and Apparatus to be used in connection therewilhfof which the following is aspecitication.

This invention relates to improvements in gun-carriages with minimum embrasures.

In other similar gun-carriages hitherto constructed the lower frame of the gun-carriage is stationary and the lifting-cylinder is connected with the upper part, so that the barrel only is lifted; but according to the present invention I make only the lifting-cylinder stationary, and the gunfcarriage as apwhole is vertically raised or lowered in order Yto point the gun or place the same in position for tiring.

2o In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure I is a side elevation, partly in sec- `tion, of my improved gun-carrage. Fig. II is a vertical transverse section, and Fig. III a horizontal section, ofthe same. Fig. IV is a plan of the guide-rod removed, showing the recoil-cylinders attached thereto. Figs. V

3o and VI are detail views, showing modifications in the arrangement of the recoil-cylinders and their accessories.

To this end the hydraulic cylinder A is L rmly connected with two bearers, C C', by

means of the cross-piece B. The piston A', by means of a cross-head, D, carries the llower gun-carriage, E, the sides of which extend'in the form of two shoulders, E E", which are arranged to move up and down in four guides,

4o F F, when the gun-carriage is raised by the piston A. Upon the frame E rests the upper portion, G, of the gun-carriage, which portion is supported by friction-rollers, and the walls of which serve as bearings for the trunnions.

4 5 The barrel may be caused to turn on the front pivotal point in various manners-for example, by means of a guide-rail, as shown in Fig. I, or by means of an embrasure-ring, as shown in Fig. VI.

5o The guides do not form part of the present carriage.

invention, and therefore to explain Fig. I it need only be mentioned that the barrel is mounted ou a block, J, sliding upon a guiderail, H, which lies parallel to the axis of the barrel, and this rail turns upon the pivotO, so that the axis of the barrel must coincide in every position with the center C. The arrangement of the guiding devices is simpler in Fig. VI, the guiding being effected by mea-ns ofan embrasure-ring which turns upon two pivots. If a horizontal movement be required, then pulleys are placed under the bearers C Gand a pivot is placed beneath O. A

Another' improvement consists in the modified arrangement of the brake-cylinders K K for the Purpose ,0i Y(lindaishii-1e the Elfes@ 0f theVY recoil. (Hydraulic brake-cylinders, as is well known, are filled with a fluid, which is forced through the perforated pistons when the piece of ordnance recoils.) The brake-cylinders, contrary to the mode of construction hitherto employed, are, according to the present invention, not attached to the gun-carriage frame, but to the barrel itself, while the piston-rods are firmly secured to some part outside of the gun-carriage. tion represented in Figs. .I to IV the brakecylinders .are attached to the sliding block J, Fig. IV, connected with the barrel, while the piston-rods are attached to the guide-rail H by means of the cross-piece L. In Fig. Vthe cylinders K K form the sliding block, while the pistonrods form thetwo guide-rails, which are pivoted at O, and the number of parts isV thus reduced by two. Fig. VI shows, by way In the construcf of barrel-guide, an embrasure-ring. The Y brakecylinders are each provided with an eye tting onto the trunnions, and the piston-rods are similarly connected to extensions of the pivots of the embrasurelring. The reverse Yofv this arrangement may be adopted, if desiredthat is to say, the piston-rods canbe connected to the barrel, and the cylinders can be secured firmly to a point outside of the gun- In Figs. V and VI the barrel-guides and brake-cylinders only are shown, while the other portions shown in Fig. are omitted. By connecting the brake-cylinders with the barrel, the embrasure is completely protected from the strain caused by the recoil of the gun,

2. The combination, with a vertically-moving frame and a sliding gun-carriage mounted thereon and supporting the trunnions, of the barrel pivoted through intermediate connections to a part of the frame distant from 'the vertical plane of the axis of said trunnions, which is' stationary as regards vertical and in! the purpose set forth. 3.- flhe combination, with avertically-mov- 4"ing gun-carriage a'ording bearings in which Ythe trunnions Work, and the barrel having dependent horizontal movement, as and for' through intermediate connections a fixed pivotal point distant from the vertical plane of 25 the axis of said trunnions, of a hydraulic press for operating said carriage, as set fort-h. 4.
