The protecting cover 17 embraces the bolt in such a way that it can be pushed, together with the latter, inside the bolt-wa)lv 25., and it is suitably provided with longitudinal and .transverse flutes, as shown in the drawing, for the purpose of reducing Ifriction. At thelfront en dv of the protecting vcover isf-provided another shoulder 26.. (see Figures l0. and 13) which is. so situatedthat when the bolt. is. drawn back vfor the purpose of opening the breech it hits against the boltl:"stop 27 and thereby limits the movement of `the bolt l(see VFigure 14).

Figures 14l and 16); that is 'to say until shortly betere .the bolt completes its outward travel. The magazine catch 32 can then be released in the usual way by hand andthe magazine takenlotll It will be 'observedthat during tiring, the magazine catch is held irrnly locked so that lit cannot become disengaged of its own accord even under the jarring which occurs during tiring, and thus the magazine cannot fall out after it has once been pushed in. The bolt stop 27 (see Figures 14 and 17) is mounted on a. lever arm 33, which is pivotally mounted Aunderneath the bolt-Way 25. On the lever arm 33 is mounted an angular projection 34, which passes under the trigger lever 35 with a clearance. This clearance or intermediate space is such that when the trigger 36 is pulledvinthe usual Way to tire the Weapon,

-the lever 35'hasI no, action on the'lever arm ther than is necessary to release the cocked firing pin-does the trigger lever come into contact with the projection 34 and pull the bolt stop 27 downwards, so that the bolt can be withdrawn from the weapon.

What I claim and desire to secure by Letters Patent of the United States is:

1. Bolt breech mechanism for fire arms, comprising a cooking cam and a cocking piece located directly on the firing pin, a locking cap closing the bore of the bolt and constructed in the form of a sleeve, said cap being closed at the rear and screwed onto the exterior of the said bolt, and a safety catch carried by the locking cap; substantially as specified.

2. Bolt breech mechanism for fire arms as claim-ed in claim 1, wherein the bore of the bolt is furnished with an abutment for the rling pin so arranged and located as to prevent contact of the cooking faces when the Weapon is iired.

3. Bolt breech mechanism for lire arms as claimed in claim l, having a bolt stop and a protecting bolt cover, which moves with the bolt and is furnished with means for preventing rotating of the locking cap, wlith means for engaging the bolt stop and with means' for actuating the ejector; substantially as specified.

4. Bolt breech mechanism for fire arms as claimed in claim 3, wherein the bolt cover is mounted at its front end on a portion of the bolt and has a projection which bears against a corresponding projection on the locking catch in such a manner that rotation of the latter cannot take place when the bolt is in the weapon.

5. Bolt breech mechanism for fire arms as claimed in claim 3, wherein the protecting cover is provided with a stop shoulder or abutmentv which, when the bolt is drawn back, strikes against the bolt stop; substantially as specifi-ed.

6. Bolt breech mechanism for fire arms as claimed in claim 5, wherein the undert'alce of the saiid shoulder or abutment on the bolt cover strikes, when the bolt is drawn back, against an arm carrying a cartridge ejector andthus brings the said ejector automatiycally into its operative position.

7. Bolt breech mechanism for re arms as claimed in claim 6, wherein the ejector, which is released by a face on the bolt cover when the breech is closed, is set by the bolt in position for locking the magazine holder in lace; substantially as specified.

n testimony whereof I affix my signature.
