noronmrrc GUN.

Application filed September 15, 1908. Serial No. 4

To all whom it may concern:

Be it knownthat I, PAUL MAUSER, privy councillor of commerce, a subject of the King of Wurttemberg, residing in Oberndorf-on-the-Neckar, Germany, have invented certain new and useful Improvements in Automatic Guns, of which the following is a full, clear,- and exact description.

The present invention refers more particularly to automatic guns and has for its object to prevent the loading and consequently the use of the weapon, if the look, but more particularly the breech mechanism, has been in any way incorrectly put together or if some part has been omitted when mounting the breech. In this way without any other means the marksman is protected from any injurious consequences whatsoever which might result owing to his want of skill or forgetfulness when putting the weapon together.

The essential feature of the invention (irrespective of any special form of construction) consists in that movable or adjustable parts are arranged on the casing of the lock or on some other immovable part of the weapon which are held out of action only when the breech mechanism iscorrectly mounted in all its parts; whereas if the breech mechanism is not correctly mounted or'if some part is missing, owing to the absence of the part in question they automatically pass into such a position that they are capable of exerting a locking action with regard to the movable breech part or other lock or discharging part.

In the present case this invention is applied to a recoil loader of the Mauser system M. 08 (shown in U. S. Patent No. 918,760), in which the closing of the movable breech. part is efl'ected by two positively controlled locking levers symmetrically supporting the movable breech part on both sides, and in which these looking or closing levers are arran ed as supporting levers along the inside of the casing of the breech and are situated with their back pivot ends in the rear wall of the casing.

In the accompanying drawings is shown a form of construction of the invention more peciflcation of Letters latent.

. particularly adapted to this weapon, and in which:

Figure 1 shows the opened lock of. the weapon with properly mounted breech mechanism, that is, withthe closing or supporting levers. inserted and .whereby conse' quently the safety device is held out of action so that the loading can be effected unimpeded in the usual manner. Fig. 2 is a vertical transverse section takenon the line A-A of Fig. 1. Fig. 3 shows the position of the parts when the breech mechanism is not properly mounted and in which the safety device has passed into the looking or safety position owing to the absence of the supporting levers and thus'prevents the complete drawing back of the chamber. Fig. 4

is a plan or top view of Fig. 3. Fig. 5 1s a.

vertical transverse section taken on the line BB of Fig. 3. Fig. .6 is a vertical transverse section taken on the line C-0 of Fig. 3, throughthe casing of the lock and through the cover. Fig. 7 isan inverted plan view of the cover with the safety device applied thereto. Fig. 7. is a plan with the cover removed, and Figs. 8, 9 and 10 are similar views to Figs. 3, 4 and 5'showing a modification and illustrate the positions of the parts with the supporting levers omitted.

As already mentioned in the preamblethe essential parts of the breech or closing mechanism of the weapon illustratedare formed by the looking or supporting levers b pivoted in the rear wall of the casing h of the lock. These levers b are positively geared. and when the breech is closed, lie inward and support the chamber at the back on both sides (the breech bolt being in the closed position) and thus occasion the locking of the breech. The present safety device is so arranged that it can come into operation wheneverthese important parts are missing. For this purpose a spring controlled arm m is arranged on the'under side of the cover at of the housing or casing II, of the lock, which arm in the case illustrated can be lifted 'upward and closes over the opening of the breech casing and is locked on to the rear wall 72. by means of a spring controlled sliding catch e.

. have been inserted then the The spring controlled arm m is provided with pins n or other suitable dGVlCGSPIO- jecting inwardly above each of the supporting levers I) while above the breech-bolt it is provided with a safetylug or'shoulder 0 or the like. The pins 11. are fitted to lateral branches of the arm m corresponding to the positions of the sup orting levers b and the safety lug or shoul er 0 is situated at the.

front end of the arm m which latter is held in position bybeing inserted in a groove p of the cover d. The front part of the breechbolt is provided on its upper surface with a stop or shoulder 2' correspondmg to the safety lug 0. If the supporting levers b pins n will rest on the same and the safety device will be held in the non-operative position as may be seen from Fig.'1, in which the breechbolt with its stop 71 can pass unimpeded to and fro, that is, without coming into contact with the safety lug 0 and can thus effect the regular loading movements. If, however, owing to defective mounting the supportlng levers are missing, there will then no longer be any support for the pins 12., so that the arm m owing to itsspring action flies downward and its lug 0 will now be situated 1n the track of the stop .71. Consequently 1t is thus impossible for the breech-bolt to per form the loading movements; the safety lug 0 according to the position of the chamber will be situated either in front of or behind the stop 7; and thus either prevent the return movement or the forward movement of the breech-bolt. Furthermore as regards the stop 6 it preferably consists of two separate parts, as shown more particularly in Figs. 2 and 4, owing to the extractor being ar ranged in the middle part of the breech-bolt.

In Figs. 8 to-lO a modification of the invention is shown, in which the spring controlled safety arm fitted to the cover of the casing of the lock is arranged as a relatively shortone-armed lever in the back portion of the cover of the lock and the safety shoulder is fitted to its rear end. In the present modification the spring controlled safety arm is formed as a relatively short one-armed lever w, the safety lug' 0 is so arranged on the rear part of the lever :22 that when the latter is in its operative position the stop 11 of the breech-bolt engages the same by its back end. Furthermore plus a are fitted to the lever :12 forming the safety arm and if the breech mechanism is correctly mounted will rest on the supporting levers b and this permit the free movement of the breech bolt. method of working of the present arrangement is exactly the same as that of the first form of construction.

For imparting the necessary spring action In all other respects theto the safety arm, a special spring 2 is provided which at the same time presses on the sliding catch e of the cover. In the first form of construction with the same object in view that spring controlled safety arm m is also so constructed that it can act as spring for the sliding catch e which, as already mentioned holds the cover at the rear wall of the casing. For this reason it is prolonged so far beyond its supporting point 79 that its rear end can engage in a corresponding recess on the front edge of the catch.

What I claim as my invention and desire to secure by patent is:

1. An automatic fire arm having a breech.

mechanism including a breech bolt, locking means, and means for locking the breech missing.

3. An automatic firearm having a breech mechanism including a breech bolt, locking means for said breech bolt, andmeans for locking said breech mechanism operating upon absence of the locking means.

4. An automatic firearm having a breech mechanism including a breech bolt, locking levers for said breech bolt, and means for locking said breech mechanism in inoperative position, said means comprising a stop normally engaging said levers, and adapted to engage said breech bolt when the locking levers are missing.

5. An automatic firearm having a breech mechanism including a breech bolt, locking levers for said breech bolt, and means for locking said breech mechanism in inoperative position, said means comprising a twoarmed stop normally en aging said levers, and adapted to engage said breech bolt when the locking levers are missing.

6. An automatic firearm having a breech mechanism including a breech bolt, locking levers for said breech bolt, and means for locking said breech mechanism in inoperative position, said means comprising an arm abutting against a fixed part of the gun cas- 1,014,660 &

10 safety arm being adapted .to move into en- K gaging position with said breech bolt when said levers are missing.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
