which the following is a full, clear, and eX-.
act description.
The present invention relates to a lrecoil fixed barrel and straight pull breech and a breech spring with a loose intermediate roller arranged beneath the breech chamber.
The invention is illustrated in the accompanying drawing in which:
Figure 1 shows a longitudinal horizontal section, showing the breech closed, the breech bolt locked and the percussion bolt cocked ready for firing. Fig. v2 shows a longitudinal vertical section showing the parts in Vposition immediately after firing and before the recoil has taken place. Fig. 3 shows a view similar to Fig. 1 showing the parts in position immediately after firing, the breech bolt being unlocked and ready to commence its breech opening movement. Fig. 4 shows a view `similar to Fig. 2 but with the parts in different positions, the breech bolt being in its rearmost position and ready to commence its breech closing movement. Fig.` 5 shows a longitudinal section through the head of the `breech bolt, showing the locking dogs and the means for operating them, both automatically and manually. y
The gun is arranged for the' detachable magazine; the case 1 is closed labove by the cover 2 retained in place by means of a spring boltl 3 and below in the known manner by the trigger. plate 4 secured by means of screws. In the rear end of the case a movable buffer 5 is fitted; said bufl'er being provided with springs '6 and held in the case by means of studs '7. Underneath the guide ledges for the breech bolt the case forms a tube for the reception of the breech spring 8; this tube is closed at therear end by a bolt 9 and its front portion is provided with guides for the spring piston 10 (with chain roller 11). A link chain 12 connects .the rear end of the breech bolt with the trigger 13 pivoted to the case in such a manner that -upon the rearward lmovement of the bolt the spring is compressed by half the length of the stroke of the bolt; in this manner the breech spring simultaneously serves as a' spring for the trigger.
The breech bolt 14 carries at its front end two locking dogs or pawls 15 rotatable about pivots 16 and under the influence of springs 17their locking heads enter recesses in the case and lock the breech bolt when the bolt occupies its closed position in the case. After tiring the breech bolt is unlocked by the action of an inertia sleeve 18v movably mounted inside the bolt and which when the projectile leaves the barrel, owing to the recoil and its own inertia effects a relative forward movement and thereby by means of the wedge surfaces 19 forces the rear ends of the locking dogs or pawls apart in such a manner that the locking dogs areY turned inward. In the subsequent recoil of the breech bolt a two-armed lever 20 rotatablymounted on the bolt and supported on a stop 21 on the gun case cocks the percussion bolt 22 in the known manner and when the bolt again moves forward is retained cocked by the trigger nibs 23. Firing is effected in the usual manner by drawing down y the trigger nib which in the present case 1s subjected to the action of a spring 24 which also actuates the pawl 25 for retaining the detachable magazine and a pressure bolt 26 for securing the trigger plate on the case. The sleeve 18 receives the percussion bolt 22 and the percussion bolt spring 27 in such a manner that the percussion bolt is first of all pressed from the rear into the sleeve whereupon the percussion bolt spring is inserted and rigidlv united with the sleeve by means of a lock bolt 28 and a stud 29.
The inertia sleeve; percussion bolt; percussion bolt spring and closing bolt Vare therefore to a certain extent united to form a wholel and are introduced from the rear into the breech bolt which is open below and retained therein by means of a stud 30. Now during the cooking and striking of theI percussion bolt in the known manner in which operations the closing bolt 28 constitutes the rearward support of the percussion boltV spring the perforation' through the inertia sleeve and the closlng bolt for the stud 30 are retained rearward so much longer that the inertia sleeve when theprojectile leaves the barrel is able to effect the forward movement described above owing to its inertia and unlocks the breech bolt. If the breech bolt is to be unlocked and opened j 'f eii'ected by inserting.. a .diagonal y slide 331 bei i by hand by means of the button 31 the latter Y -f'tween the two pawls'in manner shown in Fig. 5, in whichjtliejfaction of the button pressed inward. ron-jitsshan'k is indicated by the arrow I iny ysuch a'manner that upon the pressing inward ofthe right handpawl into the breech bolt the `slide33 'transmits this movement in thediiecti n ydia'ted .byj the also and bot-hloc'king" i' ously unlocked-"f" 'l y It will thus be senfj'tliat'up on the adjacentf-pawl 15 which is rotated about its pivot- 1'6"-50 `*that its'fore-end becomes disengaged f from.; ,the {Qrecess in fit-lie case 1. The fore-end ofthis "pawl actson,`A
the nose of "'tlie slide 33 and shifts-saine transversely tothe axis of ,the sleeve 18. The slide 33 lies with its other nose in contact with' the rear arm of the other nawl 15 so that this latter by the aforesaid shifting of the slide 33 isrotated on its pivot and becomes disengaged also from its recess in the case. The breech bolt is now unlocked and can be drawn back by means of the button 31.
. In order to prevent firing when the breechl bolt is not completely locked inwardly pro-l jecting spring noses 34 are provided on the pawls and when the locking is incomplete these noses come in front of the percussion bolt and prevent it from moving' forward (Fig. l). Inf-order, however, to permit of turning the pawls 15 inward for the purpose of opening'the breech by hand even when the percussion bolt has sprung forwardl (Fig. 3) the noses 34 must be movable and able to yield in the pawls. Fig. 5`shows the manner in which vthe noses 34 are mounted in the pawls 15 in order to fulfil this hat I claim as my invention and desire to secure by Letters Patent is:
1.`In combination, a firearm having a fixed barrel, recoil -loading mechanism, 4a breech bolt, locking dogs carried by and adapted to lock said bolt when the breech is closed, and inertia. means located in the interior of said bolt and adapted on the recoil to move forward initially to actuate said sion of' the button 312th@ Stm-thref--acts i ins locking dogs to unlock said bolt and subse- .quently .to travel rearward with said 'bolt during the opening of the breech.
initially to actuate said locking dogs to unlock said bolt and subsequent-ly to travel rearward with said bolt, and a percussion bolt and percussion bolt spring located within said inertia member.
3. Recoilloading mechanism for firearms, comprising a breech bolt adapted to move rearward on the recoil, a trigger, flexible imeans connecting the trigger with the breech 'y bolt, and a breech spring adapted to be compressed by said .flexible means during the 4.rearward vmovement of said breech bolt.
4. Recoil loa-ding mechanism for firearms,
comprising a breech bolt adapted to move yrearwardonv the recoil, a trigger, a chain connecting the trigger with the rear portion over whichsaid chain is' adapted to ride, and movable means carrying said roller and 'adapted to compress said-breech spring dur- 1 the rearward movement of said breech bo t. Y
5. In combination, a firearm having a fixed barrel, a breech bolt, a percussion bolt, locking dogs carried by and adapted to lock the breech bolt when the breech is closed, an inertia member adapted to unlock said locking dogs, and safety means adapted to interrupt the forward movement of the percussion bolt until the locking dogs completely lock the breech bolt. f
6. In combination, a firearm having a fixed barrel, a breech bolt, a percussion bolt, locking dogs carried bvand adapted to lock the breech bolt when the breech is closed, an inertia member arranged in the interior of the breech bolt adapted to unlock said locking dogs, and movable safety noses carried by said locking dogs and adapted to interrupt the forward movement of the percussion bolt until the breech bolt is completely locked by the locking dogs, said locking dogs being formed with recesses in which said safety noses can engage.
In wit-ness 'whereof I have hereunto set my hand in presence of two witnesses.
