SPECIFICATION forming part of Letters Patent No. 739,732, dated Septemioei` 22,1908.. A application sin my is. 1901. sein sesenta. on esas.)

To all whom may' concern:

ne it known that I, CARL AXEL renonce' SJOGREH, asnbjeot of the King of Sweden and. Norwey,and a residentof Stoekholm, Sweden, have invented new and useful improvements in Guns, of which the following is n specification, reference being had to the drawings accompanying and forming a part hereof.

This invention relates te improvements in. o guns, and has for ite object lo provide menus by which one or more of the operations for reloading the gun and making the same ready for a new ring-suchas releasing the breech, withdrawing the same, removing the empty 5 cartridge, compressing the msinspring, forcing a new cartridge into the barrel,.and bring` ing the breech into closed position-will be performed automatically. The firing might also be performed automatically, though the :o automstic ring in most instances is not desirable, because the cartridges thereby would be consumed in an instant withontcorresponding effect..

The invention consists, brieiiy, in provid- :5 ing in the gun one or more movable weights, heavy bodies, pistons, or the like, which on account of their inertia do not partake of the recoil of the gun, but, relative to the latter, A so to speak, move forward. This movement 3o of the weights, bodies, or the like is accomplished. by suitable mechanical connections between the said weights, bodies, or the like and one or more of the mechanisms in the gun used to effect acertain function by the said mechanisms, whereby the gun may be made partly automatic, semi-automatic, or fn ily antomatic. A weight, body, or the like arranged in a gun in accordance with my in ventionis movable in the longitudinal direc- -:,o tion of the gnn and slides by its movements insniteble guides. The movable weight or body may further be provided with one or more springs placed at one or both ends f the same, which springs by striking suitable shoulders er the like will store up a certain qn'intity of energy, which is thereupon used to eect the woz-"sing of one or more mech-.tm

able constrnctional forms of my invention are illustrated, like characters of reference .referring to seme or corresponding parts in all the figures.

Figures land 2 show in side elevations end partiel sections the parts of a gun which are necessary to illustrate the new arrangement, the looking mechanism of the breech-block 6c being shown in two different positions. Fig. v3 shows a plan view of the same part of the gun, partially in section. Fig. 4 shows in plan a somewhat modified arrangement. Figs. 5 and 6 show plans, partially insection, 65 of another form of the invention. Figs. .7 and 8 are vertical and horizontalsections of a third form of my invention.

According to Figs. l and 2, a Weight 1 is attached to thegun so as to be movable irl-7o the longitudinal directionoi the same.' Said weight may suitably be located in a, recess of the stock A ofthe gun. The rear end of seid weight is connected to the center pivot of a toggle-lever 2 3, the one part 2 of which is 75 pivoted on a fixed pin 4., whereas the other. part 3 is pivotally connected to two lovers 5 and 6. The rear ends of said levers form books 7 S, adapted to en gage with correspond the latter is in closed position, as shown in Fig. 3. The fore end of the said weight 1 is provided with a pin 9, engaging a loop 13 or the like, fixed tothe barrel and serving as a guide for the said weight 1. pin 9 of the weight l is provided a spring 131, adapted to bring back the weight to its origi' nal position. On the breech-block'10 isalso arranged a. movable weight 14, sliding on the upper side of the breech-block. In suitable 9e recesses in said weight 14 springs 15 are pro vided, which at their fore ends bear against projections 16 on the breech-block.

The working of the mechanism now de scribed is the following: When the rifle in 95 being fired recoils, the weights 1 and 14 on account of their inertie. will not take part in the'bacl-:ward movement of the ride, but tend to ireepjtne same position in space, and thus o the borrel.) The weight i. hereby tonele-lever in the position shown levers 5 (l are breng-iin ing projections on the breech-block 10 when 8o' Around the said "sr-werd relative to tire gun, (toward 'tile too c esmas the latter thus being released. While the weight 1 is releasing the breeohblock the weight 14 compresses the springs 15. As soon as the recoil of the rifle ceases the springs 15 5 push the weight 14 backward, so that the latter by its fore end strikes the projections 16 of the breechblock and moves the same backward. A

in Fig. 4 the movable weight that is connested to the lookin g mechanism o the breechblock is formed in the shape ot s cylinder 101, surrounding the rear' part of the barrel B, the rear ond oi said cylinder 101 being connected to the center pivot of toggle-levers 2 01 202, said toggle-levers being movable in the horizontal plane. Each of the parte of the said toggle-lever is pivotally connected to a two armed horizontallypivoted lever 505. The rear ends' of these levers are, es described with reference to Figs. 1 to 3, formed as hooks adapted to engage with corresponding notches in the breech-block. The working of the modication now described is analogous with the arrangement above described.

1n the modification shown in Figs. 5 and 6 onlyone weight 17 is provided, which is placed on the breech-block in the same manner as the weight 14. (Shown in Figs. 1 to 3.) The said weight 17 is provided with two cam-slots 18, each of which engages with one ofthe pins 19 20, fixed to a horizontally-pivoted twoarmed lever 21 22.- The said cam-slots 18ers of such form that when the weight 17 moves backward the fore ends of the levers 2122 are turnedoutward. These ends of the said levers 21 22 are provided with slots 23, with which engage corresponding projections or hooks 2e when the breech block is closed when the said pins 19 20 areiabout at the middle of the said cam-slots. The rear parts of the latter are parallel with the longitudinal direction of the barrel, so as to keep the said levers 21 in position when the weight 17 -moves forward. In a snitablerecess in the weight 17 is placed a spring 25, the fore end of which bears against a projection 26 of the breech-block. When the ride in being tired recoils, the weight 17 on account of its inertia. will move forward relative to the ride. The spring 25 will thereby be compressed and the cam-slots be moved relative to the seid pins 19 20,50 thatthelatter will engage with the rear ends of the said slots 18. Whenthe recoil ceases, the spring 25 will push the weight 17 backward, whereby the carn-slots 18 will disengage the levers 21 22, as shown in Fig. 6. Subsequently the weight 17 will bring the breech-block backward in the same manner as described with reference to Figs. 1 to 3. In order that the weight 17 may not strike directly against the said projection 26 of the, breech-block, it is preferable to provide also in front of the said projection r. spring 27, which wiil take np the knock of the breechd5 block.

7 and Sillnstrate s form of my inven- 5.

.tion adapted to be applied to auch breech;

pieces which are used in Mouser riiles2""'li1eAJ rotatable breech-block is provided at its fore end with two projections 28, `adapted to en- 7o gage with s flange 29 on a. part 30, attached to the barrel. The said flange 29 is provided with two slots 36, by means of which the seid projections can be disengaged from the said ilenge 29 when the breech-block has been 75 turned in a corresponding position. On the breech-block 31 i's arranged a movable weight 32, provided with two pins 33, each engeginga spiral slot 34 of the breech-block 31. In the weight 32 two springs 35 are provided, which 8o will be compressed when the .weight moves forward ou the ride by the recoil of the same.

When the recoil ceases, the weight 32 will be pushed backward, whereby the said pins 33' will be moved in the spiral slots trthus tum- 35 ing the breech-block 31 so that the projections 28will be moved opposite the said slots 36 of the flange 29. The breech-block will subsequently be pushed backward by the weight 32 in the manner above described.

It will be easily understood by tnose skilled in the art that the arrangements now described may be modified in men-y ways without dev-isting from the rinoiple of my iuvention. .As before state the said weight or block may be connected by suitable gearings to any or all the mechanisms necessary for making the gun more or less automatic.

Having now 'described my invention, what I claim, and desire tosecnre by United States Letters Patent, is

1. The combination with a gun, of a mov able weight on the breech-block of the gun adapted to move forward on acconntof its inertia when the gun recoils, springs between the said weight and the breech-block adapted to be compressed when the former moves forward andy to throw the said weight backward when the recoil of the gun ceases, means for locking the breech-blockin closed position, and means for unlocking the breech-block, substantially as and for the purpose set forth.

2. The combination with a gun, of a movable weight on the breech-block of the gun adapted to move forward on account of its inertia. when the gun recoils, springs between the said weight and the breech-block adapted to be compressed when the former moves forward and to throw the said. weight backward when the recoil of the gnu ceases, a locking x2 mechanism for the breech-block, and mechanical connections between the said weight and the breech-block adapted to unlock the latter when the said weight moves backward, sub stantially as and for the purpose set forth.

In testimony whereof I have hereunto sbscribed-my name in the presence of two sub scribin'g witnesses.

CARL AXEL THEODSR SJOGREN.
