Description

Patented Aug. 4, 1931 UNITED STATES rarer oFFicE EUGENE SCHULER, OF BUDAPEST, HUNGARY, ASSIGNOR OF ONE-HALF TO THE FIRM JOSEF SCHULER A. G. ERSTE UNGARSCHE STAHLSCHREIBFEDER, FEDERHALTER- UND INDIGOCOBTERPAPIERFABRIK, AND THREE-TENTI-IS TO JOSEPH BENKE, BOTH OF BUDAPEST, HUNGARY SAFETY PROJECTILE FOR GUN PRACTICE ANB GUN BARB'ELS SUITABLE FOR THE SAME Application filed .Tune 26, 13:30, Serial No. 463,948, and in Hungary April 15, 1929.
It is a drawback of the safety projectiles employed upto now for gun practice purposes, that they are not suitably guided in the draw channel of the gun barrel, and ac- ,v. cordingly it is not possible to shoot with them at marks in a sufliciently accurate manner, and that on the other hand, they do not produce suiiicient back-thrust, which latter would be necessary to enable the soldier to get accustomed to the reaction caused by sharp shooting.
The devices according to the present in vention, viz. a safety projectile for gun practice and the gun barrel suitable for such projectiles eliminate these drawbacks.
The invention consists essentially in a lead projectile having the form of a truncated cone, as usual for air guns, being cemented on to a paper-shell safety cartridge of known type, and in the loading chamber of the gun barrel to be used for such safety' cartridges being shaped in such a manner as to ensure that the front part, of cylindrical shape, of the lead projectile will at the occasion of the projectile being placed into the gun barrel, penetrate or respectively be jammed into the entrance of the draw-channel of the gun barrel, and thus will ensure guidance of the projectile from the moment of firing onwards.
An embodiment of the present invention, shown by way of example is illustrated on the accompanying drawings in which Fig. 1 is a view of the safety projectile.
Fig. 2 illustrates the safety projectile, partly shown in section, together with a section of the loading chamber of the gun barrel.
Fig. 3 is a View of the machine-gun baro rel to be used in connection with the safety cartridge according to the present invention.
On the front part,'of conical shape of the paper shell la of the safety cartridge for gun practice l a lead projectile 2 of known type is cemented, in such a manner that the open bottom part of the lead projectile is placed concentrically on the end of the paper cartridge shell which has previously been immersed into some kind of cement- "0 ing substance, as for instance glue, celluloid lacquer or the like. The cylindrical part 3 of the lead projectile 2 is at this moment parallel to the longitudinal centre-line of the safety cartridge.
The loading chamber of the gun or machine-gun is shaped in such a manner as to ensure that when the' safety cartridge is placed in position, the cylindrical portion 3 of the lead projectile 2 will penetrate or respectively be jammed into the entrance of the draw-channel 4 ofthe gun, the guiding of the projectile being thus assured from the moment of iringAonward.
rPhe barrel for machine-guns for purpose of field practice 5 differs from ordinary machine-gun barrels not only by its loading chamber being shaped in the manner `described above, but also by being slightly shorter than an ordinary machine-gun barrel, and by there being provided on its front end a square-shaped milling, instead of the usual hexagonal milling, on which the pipe Spanner for screwing the pipe into its frame is placed; by these means, the possibility of confusion with machine-gun barrel for sharp shooting is avoided.
Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed,l declare that what I claim is 1. A safety projectile for gun practice purposes and a gun barrel suitable for the same, in which a lead projectile per se known is cemented or fixed to the front end of shape of a paper-shell cartridge, whilst the loading chamber of the gun is shaped in such a manner as to ensure that when placing the safety cartridge in position, the cylindrical front end of the lead projectile will penetrate or respectively be jammed into the entrance of the draw-channel of the gun barrel.
2. An embodiment of the gun-barrel, such as claimed in claim l, for machine-guns used for field practice, in which a square shaped milling is provided on the front end of the gun-barrel, in order to avoid it to be confounded with a barrel for shooting sharp cartridges.
