2 claims, (m42-1s) This invention relates to gun constructions, and more particularly to loading and ring mecha-` nisms of riiies, including loading mechanisms of the type in which bullets are taken from a magazine and brought into ring position.

One of the principal objects of the invention is to provide a construction of a rifle mechanism of the type where the bolt is locked at the head, in which only two movements of a swinglever arev required. l y

A kfurther object is to provide a rifle mechanism of the type in which high power cartridges may be used.

A further object is to provide a riie mechanism of the type with strong locking means.

Another object is to provide a construction in which a minimum number of parts complete ly operate the mechanism, and in which such parts are strong anddurable. I

Another object is to provide a construction in which the exchange of cartridges can be done easily and speedily and with a minimum of energy.`

Another object is to provide a mechanism that is not complicated, and which will work under stances.

Another object is to provide a rifle of the typeY that the gunner can keep on his shoulder for reloading, as the bolt is covered and does not reach the gunners face.

Another object is to provide a rifle of the typeV where the mechanism is completelyY enclosed in the rifle-stock for reducing vibration and providing a maximum of accuracy.

Further objects and advantages of the invention will be in part set forth in the following description and in part will be obvious therefrom without being specifically pointed out.

With the above and other objects of the invention in view, the invention consists in the novel construction, arrangement and combination of various devices, elements and parts, as

set forth in the claims hereof, certain embodi Fig. 4 is a cross section taken along the line 4--4 ofFig.1;

Fig. 5 is a cross section similar to Fig. 4, but showing the breech-bolt actuating member in its I lower position; and

Fig. 6` is a longitudinalsectional view, similar to Fig. 1, but showing the lever and the breech bolt moved to its eXtreme position to the right.

In the'following description of the drawings, in which similar numerals indicate similar parts, lll designates a riiie-stock, which carriesy a barrel I' and a receiver II, the rear end of which is closed by a screw l2. A hollow space I3 is provided within said rifle-stock I0 to receive and hold a plurality of cartridges, and a spring I4 is provided therein to press the cartridges'upwards. On the lower side of the rifle-stock I0 a metal strip I5 is fastened which provides the bottom for said hollow space I3, and against which the lower end of said spring I4 is bearing. Screws I6 connect and hold together the receiver II and the-rifle-stock l0.

' A cylindrical breech bolt I'I is slidably mounted ina central tubular boring I3 of the receiver II. The bolt I'i carries three lugs, two lugs 20 of which mounted oppositely near the front end and one lug a mounted near the rear end of said bolt l1, normally locked'in corresponding recesses 2l and ZIa, respectively, of the receiver II when the bolt I1 is in its yforward position. The tubular boring I8 has side grooves 19 to receive the

lugs

20 and 20a when the bolt I7 is in motion. A follower member 22 rests on top of the spring I4 and carries the cartridges. The bolt Il has a centrall boring 23 in which the firing pin 24 is located and also a helical spring 25, whichspring presses with one'end against a flange 26 that is connectedto said firing pin 2li', and with its other end presses against a member 2l, said member being screwed into said central boring 23 and serving as a cover for it near its rear end. The member 21 has acentral boring to provide passage for the ring pin 24.

lA guidingl element 28 is mounted in the rear portion of said central `boring 23, and extends therefrom, and is provided with a circular groove 3D, into which groove a plurality of screws 3l protrude' for revolubly connecting the bolt I'I with said guiding element 28. At its rear end said guiding element 28 is cut away vertically to form a hat side 32, and a guiding arm 33 of a lever 34 extends with its upper portion engaging said flat side 32. The guiding arm 33Y operates in a slot in the rifle-stock I0, and is bifurcated on itsl upper end at 35 thereby embracing in slidable l connection a horizontal pin 36 carried by said guiding element 28 on the at side 32. The lever 34 is pivoted at 31 to the rear end of a link -38,

said link being pivoted near its forward end toV end the breech-bolt actuating member 4I has a recess 44 to receive the free arm 45 of. an L,- shaped member 46, connected with its other arm 41 to the bolt I1.

The rear portion of the ring pin 24 carries a cooking piece plate 41 for engaging with said plate a vertical leg 48 of an L-shaped sear 50 which is supported by a Sear-spring 52 and is pivoted as shown in Fig. 1, or slides in a slide 59. as shown in Fig. 2. The horizontal leg 5I of the sear 50 is located adjacent an upper arm 52 of a trigger 53, which trigger operates in a slot of the rifle-stock I 0, and is pivoted at 54 and is held in a predetermined position by a trigger spring 55 near its lower end, said lower end reaching through a slot of the metal strip I5' outsideV of the rifle-stock I 0.

The lever 34 Vis bent on its lower end and in its normal position rests against the under side of the rie stock surrounding the lower end of the trigger 53.

By having, as above described, all the mechanism within the surface of the rifle-stock I 0 and the receiver I I, a streamlined rifle is provided, the advantages thereof being obvious to those skilled in this art, without the necessity of special mention.

The operation of the invention is as follows: I The firing of the bullet is ina substantially conventional manner. After the bullet has been fired, the gunner swings the lower portion of the lever 34 forward until the limit of this movement is reached. At this time the old cartridge is ejected in a manner which may be similar to a' Mauser action rie. Thereupon theJ gunner swings the lever 34 back to its original position, thereby loading the gun for the next shot. Such a procedure is old, but new mechanism is used in this invention, which operates as below described and which greatly simplies the four movements heretofore used by the Mauser type, substituting the swinging of the lever, an operation requiring less energy and less attention by the gunner.V

Through the initiation of the said forward swinging movement of the lower portion of the lever 34, the link 38 which is pivoted to the riflestock I8 at 40 swings downward and causes the breech-bolt actuating member to slide downward. On this downward movement the breech bolt actuating member 4I engages the arm 45 of the L-shaped member 4B causing thereby a rotation of the bolt I1 around its longitudinal axis unlocking thereby the

lugs

28 and 20a from the corresponding recesses 2I and 2Ia, of the receiver II. This downward movement is terminated when a stud 49 attached to the breech bolt actuating member reaches a corresponding removable stop 59 provided with the rifle-stock, after the bolt has rotated 90 degrees.

Said stud 49' causes the termination of the downward movement of the breech bolt actuatthe projected end of the screw I2.

ing member as soon as it abuts against the stop 59 and, as the gunner presses on against the lower portion of the lever 34a swinging movement of the guiding arm 33 around the pivot 31 is brought about, said guiding arm swinging in a slot of the rifle-stock I0 and a slotted portion of the receiver II. The bifurcated upper end of said guiding arm 33, through its engagement with pin 36 causes the bolt together with the ring pin to slide rearwardly into the position shown in Fig. 6, Where the swinging movement is terminated by the cocking piece plate 41 reaching The end of the downward movement of the link 38 and the beginning of the swinging movement of the lever 34 are shown in Fig. 2.

While the bolt I1 is being retracted, the old cartridge will be ejected and the new cartridge will be brought in under the pressure of the spring I4 from the hollow space I3.

Through the following backward swinging movement of the lever 34 the bolt is brought back to its original position, whereas the plate 41 of the firing pin 24 will be engaged during the forward movement of the bolt by the vertical leg 48 of the Sear 50 under the pressure of the spring 52 against the power of the helical spring 25. Thereby the ring pin is brought out of reach of the cartridge and, ready for action through release by the trigger 53.

The continuing of the backward swinging movement of the lever 34 willbring the link 38 into its original position, thereby sliding the breech bolt actuating member 4I to its initial position, and the resilient latch 39 will engage the groove 39. The recess 44 engaging the arm 45 0f the L-shaped sear 46 will cause the lugs 2l) and 20117J on the forward and rearward ends of the bolt I1 to engage the recesses 2| and 2Ia of the receiver I I thereby locking the bolt I1 in this original position. Through pulling the trigger against the tension of the trigger springr 55 the upper arm 52 of said trigger 53 depresses the L-shaped sear 50 against the pressure of the spring 52 releasingthereby the ring pin for ring. At the subsequent retraction of the bolt by the afore described swinging movement of the lever 34, the plate 41 of the ring pin 24 and also the lower side of the bolt I1 will depress the vertical leg 48 of the L-shaped sear 50 during its rearward movement owing to the tilted shape of said vertical leg 48.

In orderA to clean the tubular boring I8 properly, the bolt is retracted, the screw I2 is loosened, the pivot 31 detached and, thereafter the bolt can easily be removed from the receiver.

The advantages of the invention have been, in part, referred to in what is said above, and in part will be obvious without being specifically set forth.

I do not limit myself to the particular details of construction which are shown in the accompanying drawings and described in this specication, as the same refer to only certain embodiments of the invention, an'd it is obvious that the same may be modied, within the scope of the appended claims, without departing from the spirit and scope of the invention.
