SPECIFICATION forming part Of Letters Patent N0. 621,286, dated March 14, 1899.

Application filed December 31, 1897. Serial No. 665,064. (No model.)

To all whom it may concern.-

Be it known that I, ADOLF Rnsow, a citizen of the German Empire, residing at Essen, Germany, have invented new and useful Improvements in or Connected with Gun-Carriages, of which the following is a specification.

This invention relates to a firing-brake for wheeled gun-carriages, comprising a spur which diminishes the recoil and automatically runs the gun out again. This spur when in action protrudes in a downward direction from the gun-carriage and is connected with the trail of the carriage by means of a horizontal bolt mounted so as to be capable of sliding in longitudinal slots in the trail of the carriage in such a manner that when the said bolt is in its position the spur can be moved around its axis and be brought over the trail of the carriage onto the upper side of the carriage-walls. This movement of the spur can be accomplished when the carriage is stationary, because at that time the springs of the brakes hold the bolt carrying the spur at its end position in the said slots in the carriagetrail. The possibility of folding or turning the spur upward, as stated, presents advantages beyond those carriages not so provided in that when the spur is not in use no part of the same, according to this invention, projects below the carriage-trail, and consequently, particularly when the gun is being moved over uneven ground or through ditches, the spur cannot stick in the ground,and thereby cause damage to the gun, or to the horses dragging the same, or to the harness, and all fatal stoppages consequent thereon are obviated.

In the accompanying drawings an example of the firing-brake constructed according to this invention is shown in Figures 1 and 2 in longitudinal section and in plan, respectively. The spur is shown in Fig. 3 in its turned-up inoperative position and in Fig. 4 in its position for firing. From these figures it will be perceived that in its lower position the spur is driven into the ground, with its spade-shaped part A slightly inclined toward the rear,by the weight of the gun-carriage resting on it (see Fig. 1) and also by the action of the recoil upon firing the first shot, the spur by said penetration thus offering resistance to the carriage being pushed backward.

The two rearwardly-inclined arms A of the spur embrace the carriage-walls and are connected at their. ends to the bolt B, which is mounted horizontally in the longitudinal slots F. The free space between the arms A, the spur-blade A, and the bolt B allows of turning the spur out of its position shown in Fig. 4 (without hindrance by the limbering ring or eye arranged on the carriage-trail) into the upper position shown in Fig. 3, in which it rests with its lower edge upon the upper surface of the carriage-walls. In this position the spur can be prevented from all movement by means of the chain J, (shown in Fig. 4,) the cross-piece K of which is passed through the eye L, although when the gun is limbered up the limber-arms would of themselves prevent the spur from falling back and down. Also during firing it is advisable to employ the chain J in the manner shown in Fig. 4, because then the raising and moving of the carriage-trail for lateral training is thereby facilitated.

The middle part of the bolt B is carried in a pivotal manner through the corresponding holes in the sleeves G, the latter being situated at the ends of the guide-rods D of the springs E between the side pieces of the carriage-walls. The collars S (shown on the right hand of the drawings) of the guide-rods D serve as rearward abutments for the springs E, while their forward abutments are formed by the sliding sleeves or bushes G, which are suspended by means of their lateral pins or trunnions pivotally in the hangers H, fixed to the carriage-body. The springs E having initial tension prevent the trunnions of the bushes G leaving the open bearings in the hangers H.

To be able to readily remove the springrod of the spur from the gun-carriage, a screw-bolt M is screwed into each guide-rod D, which screw-bolt, through the thrust-rings N, acts upon the sliding sleeves G. When the screw-bolt M is screwed far enough into the guide-rod D to take the trunnions of the sleeve G out of the bearing in the hanger H, the spring-rod D can be removed from the gun-carriage. To reinsert the spring-rod D,

I is as follows: The recoil, which has driven the spur firmly into the ground and has moved the gun back, causes the gun-carriage walls to slide with their longitudinal slots F over the bolt B, and the springs E are compressed until the forward surfaces of the slots F strike against the bolt B. As the springs cannot now be compressed to any further extent the spur acts from that moment as a rigid spur rigidly connected to the gun-carriage. After the termination of the recoil movement the springs expand again, and, bearing against the flanges of the guiderods D, which are connectedwith the fixed spur by means of the sleeves C and the bolt B, cause the gun to be moved forward again completely or almost into its initial position.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. A recoil-brake for field-gun carriages consisting of a spur A having arms A projecting approximately at right angles from the spur A and connected to the outer ends of a bolt B traversing the trail, so that the spur may be swung around the end of the trail to the top of the same, substantially as and for the purpose specified.

2. A recoil-brake for field-guns consisting of a spur A having arms A projecting approximately at right angles from the spur; the arms A pivoted to the outer ends of a bolt B traversing the trail and guided Within longitudinal slots F of the trail, and an elastic medium interposed between the bolt B and the carriage-body, substantially as and for the purpose specified.

'3. A recoil-brake for field-gun carriages consisting of a spur A having arms A pro jecting approximately at right angles from the spur; the arms A pivoted to the outer end of a bolt B traversing the trail, and guided Within slots F of the trail, sleeves O mounted on the bolt B, guide-rods D entering sockets in the sleeves O and provided at their rear end with collars S, sliding sleeves G mounted on the rods D and suspended from the carriageframe, springs E abutting against the sliding sleeves G and the collars S, and thrust-rings N adjusted by screw-bolts M, actuating against the sliding sleeves C, substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

'ADOLF RESOW.
