GUN WITH REG'OILING BARREL.

Specification of Letters Patent.

Patented May as, 1907.

Application med June 22,1906. Serial Nb. 322,902.

many, have invented certain new and useful Improvements in Guns vrels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvemcntsin guns with recoiling barrel and has for its obwith Recoiling Barject to -construct the gun so as to be able to,

While the forward motion spring may remain with in the cradle in the necessary initial tension. For this purpose a disk is inserted between a flange of the brake cylinder and the end of the.forward motion spring abutting against said flange, which disk after the removing of the brake cylinder abuts against a flange of the cradle and secures thereby the forward motion spring in the cradle. flange of the cradle may be constructed so as to serve as atension screw for the forward motion spring. Instead of this however the flange of the brake cylinder may serve for the said purpose in the manner heretofore known.

My invention is adapted essentially for guns which must be transported in single parts and wherein it is desirable or prescribed to have the weight of the parts within certain limits. In the known guns with recoiling barrel it is necessary for removing the brake cylinder to loosen a tension nut and then to remove the spring from the cradle. If the whole is then remounted the spring must be brought again under tension. All this requires much time and labor.

In the accompanying drawings Figure 1 is a sectional side elevation of a gun constructed according to my present invention. Fig. 2 is a longitudinal section through the fore end of the cradle, the brake cylinder being removed. Fig. 3 is a similar section showing a modification with the brake cylinder in its place. i

In the construction shown by Fig. 1 and 2 the brake cylinder a is fastened in a wellknown manner to the'horn b of the barrel 0. At its fore end the brake cylinder a is proremove the brake cylinder out of the cradle,

The

vided with a flange d, against which the forward motion spring e abuts by means ofa loosely inserted disk The latter is supported at the same time against a flange g of a sleeve h provided with a screw thread on 1ts outer surface and screwed mto a female sleeve lc'fastened in the cradle i.

It will be seen, that during the recoil of the gun barrel and of the brake cylinder the spring a is compressed by the flange d and the disk f, when the spring by pressing on the disk brings the brake cylinder and the gun barrel back to their initial position.

If it is required to remove the brake cylinder the fore cover Z of the cradle is opened and the brake cylinder disconnected from the horn b in a well known manner. Then the brake cylinder is Withdrawn from the fore end, when .the spring 6 being under an initial tension presses the disk fagainst the flange g thereby being held securely within the cradle. The sleeve his a screw for bringing the spring under a desired tension, this tension being maintained also if the brake cylinder is removed.

In the modification shown by Fig. 3 the flange dis not provided directly on the brake cylinder but on a sleeve m serving as a tension screw for the spring a and screwed. on to the brake cylinder. E

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. In a recoil brake for guns, a detachable recoil cylinder, a stop carried by the cylinder, a loose disk bearing upon the stop, a forward motion spring bearing upon the'disk to return the parts after recoil, and a stop carried by the cradle in the path of the disk and independent of the cylinder to limit the relaxation of the sprin 2. In a recoil braIce for guns, a cradle, a detachable recoil cylinder within the cradle,

. a stop carried by the cylinder, a loose 'disk bearin upon the stop, a forward motion spring bearing upon the disk, and a stop carried by the cradle to limit the relaxation of the spring, the two stops lying in substantially the same plane transversely of the cylinder.

3. In a recoil brake for guns, a recoil member'moving with the gun, a forward motion spring bearing withone end on a fixed abutment and with the other end on the recoil member, and means interposed in the path of the relaxing spring to limit the movement of the same when the recoil member is withdrawn.

4:. In a recoil brake for guns, a cradle, a forward motion spring within the cradle bearing with one end against a fixed support, a detachable recoil member movable within the cradle and surrounded by the spring, a stop carried by the recoil member and serving as an abutment for the other endof the spring during recoil, a loose disk between the recoil member stop and spring, and an adjustable stop on the cradle in .the path of the relaxing spring to engage the disk when the recoil member is withdrawn.

r 5. In a gun with recoilin barrel the combination with a cradle of a rake cylinder, a forward motion spring, a flange on the brake cylinder, a loose disk between this flange and the forward motion spring and a flange connected with the cradle and serving as a supportfor the said loose disk if the brake cylinder is removed, substantially as described and for the purpose set forth.

6. In a gun with reeoiling barrel the combination with a cradle of a brake cylinder, a a flange on the brake the forward motion spring, a sleeve screwed into the cradle and a flange connected with this sleeve and serving as a support for the said loose disk if the brake cylinder is removed, substantially as described-and for the purpose set forth.

In testimony whereof I have aflixed my signature to this specification, in the presence of two witnesses.
