Dec. 1932- R VON FROMMER HAND GUARD FOR AUTOMATIC FIREARMS Filed March 23, 1932 Patented Dec. 27, 1932 @NETEE ETATEfi FATENT errata RUDOLF VON FROMMER, OF BUDAPEST, HUNGARY HAND-GUARD FOR AUTOMATIC FIREARM S Application filed March 23, 1932, Serial No. 600,740, and. in Hungary March 24, 1931.

The invention relates to an improved handguard for automatic fire arms and more particularly to a further modification and perfect-ion of the hand-guard protected in the patent Serial No. 491,571/1930.

The above mentioned patent refers to a sliding cover and a hand-guard; the latter was a projection made integral with the gunstock or constituting a separate part secured on the same and signed by 8 in the drawing of said patent. This projection was arranged under the path of the sliding cover and had the destination to prevent that the hand of the shooter, when shooting may touch the fire arm above this projection. The breech of automatic fire arms at automatical operation slides with a very great speed backwards and consequently the handle of the breech is also rapidly moved to and fro, and

this fact may be dangerous for the shooter.

In order to avoid this danger it was already proposed to apply a handle capable of being disengaged, this however requires the application of complicated mechanisms which are to be avoided in fire arms used in war.

When the hand of the shooter comes accidentally behind the handle moving speedily backwards, this prevents not only the regular operation, that is to say the return movement, but also the hand catching the fire arm behind said handle will be hurt. This was hindered by the projection 8 described in the above mentioned patent, which project-ion served as a limit for the upwards movement of the left hand of the shooter.

At this arrangement it was still possible to pass the confine constituted by this projection, as the passing could not be surely prevented by the same.

The object of the present invention is to construct said projection in such a manner, that this dangerous mode of catching the fire arm should be rendered impossible. While the arrangement according to the above mentioned patent showed only a confine, the present construction makes the wrong catching quite impossible. This is attained by a construction of this projection, 50 which renders the catching of the latter painfully disagreeable for the shooter. In order to accomplish this'task, the smooth pr0jection of the above mentioned patent will be provided with sharp edges or teeth, so that the seizing of the same will be impossible. At this arrangement it is not necessary to call the shooters attention to the fact that he has to put his hand only below this projection, but not on or above the same as when touching the fire arm on or above the projection according to the invention, he will withdraw his hand immediately, because the edges and teeth prevent the catching of the fire arm on this place, and much less is possible to press the fire arm against the shoulder of the shooter. In order to prevent every possible hurting of the hand pushing forward the breech when the automatic fire arm is operated manually, the teeth of said projectlon may have the form of forwardly directed saw-teeth; thus the forwardly moving hand is not hindered in its free movement.

In the accompanying drawing one form of realization of the invention is shown by way of example.

Fig. 1 is a side elevation of apart of the fire arm. 7

Fig. 2 is a top plan view of the same.

Fig. 3 is a section taken on line. III of Fig. 2.

After the explanation given above it is a further description of the invention scarcely necessary. It is easy to conceive, that the catching of a projection 2 provided-with sharp teeth 1 is impossible. Manually operated fire arms must be, as it is known, caught firmly because of the kick, and this toothed projection cannot be even lightly caught, and much less firmly seized Without painful hurtingof the hand, so that a projection of this kind obliges the'shooter to shun the same of the hand do not touch these teeth at all when opening said breech, but when closing the same the forward moving hand will touch the oblique side of the pyramidal teeth and 5 will glide on them without hurting itself.

I claim:

1. In an automatic fire arm, a hand-guard constituted by a protecting projection of the gunstock arranged under the path of the 1 sliding cover, sharp teeth on said projection adapted to make disagreeable, that is, painful the catching of said projection.

2. In an automatic fire arm, a hand-guard constituted by a protecting projection of the gunstock arranged under the path of the sliding' cover, teeth with sharp points of said projection adapted to make disagreeable, that is, painful the catching of the latter.

3. In an automatic fire arm, a-hand-guard constituted by a protecting projection of the gunstock arranged under the path of the slidingcover, forwardly directed sharp saw teeth on said projection extending to the front and adapted to make disagreeable, that is,.painful the catching of said projection. r r I r 4. In an automatic fire arm, a hand-guard constituted by a protecting projection of the gunstock arranged under the path of the sliding cover, forwardly directed sharp saw teeth on said projection having the form of pointed pyramids and adapted to make disagreeable,that is, painful the catching of said pro jection.

5. In an automatic fire arm, a hand-guard constituted by a separate part arranged on r V :3

the gunstock under the path of the sliding cover, sharp teeth on said part adapted to make disagreeable, that is, painful the catching of the latter.

6. In an automatic fire arm, a hand-guard constituted by a separate part arranged on the gunstock under the path of the sliding cover, teeth with sharp points on said part adapted to make disagreeable, that is, paing ful the catching of the latter. j 7 w 7. In an automatic fire arm, a hand-guard constituted by a separate part arranged on the gunstock under the path of the sliding cover, forwardly directed sharp saw teeth of said part adapted to make disagreeable, that is, painful the catching of the latter.

8. In an automatic fire arm, a hand-guard constituted by a separate part arranged on the gunstock under the path of the sliding cover, forwardly directed sharp saw teeth of said part having the form of pointed pyramids and adapted to make disagreeable, that is, ainful the catching of said part.
