Description
Aug. 8, 1944. H. R. AUDET BLANK FIRING SAFETY ATTACHMENT Filed July 8, 1942 gwuc wfon Herbert R .Au1:1ei'
Patented Aug. 8, 1944 UMTED STATS (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) 2 Claims.
The invention described herein may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.
This invention relates to firearms and particularly to a blank firing safety attachment therefor.
It is often desirable to fire a standard firearm with a blank cartridge not only to test the functioning of the firearm but also in connection with field maneuvers of the armed forces or other types of simulated warfare. It quite probably happens that through inadvertence, a loaded cartridge may be inserted in the gun and fired, although the operator believes he is only firing a blank cartridge. The resulting peril to life and property is obvious. The danger of substitution of loaded cartridges for blank cartridges is increased in connecttion with modern firearms of the automatic type which for the most part utilize an almost totally inclosed box type magazine. 'Ih-e enclosure of the cartridges by the magazine of course renders their identification as blanks more difficult.
It is accordingly an object of this invention to provide a blank firing safety attachment for a magazine type firearm.
It is a particular object of this invention to provide a blank firing safety attachment for the type of firearm disclosed in U. S. Patent No. 1,293,022 to Browning whereby it will be impossible for the operator to load any magazine except those magazines containing blank cartridges.
The specific nature of the invention as well as other objects and advantages thereof will clearly appear from a description of a preferred embodiment as shown in the accompanying drawing in which:
Fig. 1 is a partial side elevational view of a firearm similar to that disclosed in U. S. Patent No. 1,293,022 showing a magazine assembled to a receiver.
Fig. 2 is a cross-sectional view taken along the plane 2-2 of Fig. 1.
Fig. 3 is similar to Fig. 1 except that it is shown partly in longitudinal section.
Fig. 4 is a partial end elevational view of a magazine showing a longitudinal view.
Fig. 5 is a top elevational View of a pin, a safety attachment, and a magazine respectively.
In Fig. 1, there is shown a receiver assemblage I of a. firearm similar to that disclosed in U. S. Patent No. 1,293,022 to Browning. A magazine 2 is provided of standard shape with the exception of a longitudinal groove 2a formed in the upper front narrow side of the magazine. The Wall at the lower end of this groove forms a stop shoulder 2b. It should be understood that only magazines having such a groove will be loaded with blank cartridges. The safety attachment 5 comprises a U shaped member having aligned openings 5a. in each arm. The attachment is secured to the rifle by means of a pin 3 which is substituted for the standard gas cylinder tube retaining pin and which enters the hole in the receiver provided for the gas cylinder tube retaining pin. The pin 3 has the usual locking extension 3a and the usual handle member 4 with a locking ball 40. on its end. The length of the pin 3, however, is somewhat longer than the standard pin. The attachment 5 is securely fastened to the bottom of the receiver adjacent the magazine opening by inserting the pin 3 through the aligned openings 5a and the receiver hole. The pin 3 is inserted in the usual manner with the handle 4 horizontal. The pin is then rotated by the handle 4 and the looking extension 3a engages the standard cooperating member (not shown) within the receiver. Rotation of the pin 3 from this position is prevented by the locking ball 4a engaging a slight depression in the side of the receiver.
The attachment 5 is provided with an extending nose 5b which projects into the magazine opening of the receiver and hence lies in the path of any magazine being inserted in the rifle. If a blank cartridge magazine 2 is attempted to be inserted in the rifle, the nose 5b enters the groove 2a and permits the insertion of the magazine. If any other type of magazine, particularly a standard magazine bearing loaded cartridges is attempted to be inserted in the gun, the nose 5b will abut against the ungrooved sides of such magazine to prevent the insertion.
I claim:
1. A blank firing safety attachment for a magazine firearm comprising in combination, a magazine adapted to be-loaded with blank cartridges.
said magazine having a side wall and a groove therein extending downwardly from the top of said wall, and a member adapted to be secured to the firearm having a tongue adapted to project into overlapping relationship with the magazine opening of the firearm, said tongue adapted to cooperate with said groove in said magazine whereby'only said grooved magazine may be inserted into the magazine opening of the firearm.
2. A blank firing safety attachment for a. magazine firearm comprising in combination, a mag- GFECE azine adapted to be loaded with blank cartridges, said magazine having a Side wall and a groove therein extending downwardly from the top of said wall, and a U-shaped member adapted to surround the base of, the receiver of the firearm and to be secured thereto by a transverse pin, said U-shaped member having a tongue adapted magazine opening of the firearm, said tongue adapted to cooperate with said groove of said magazine whereby only said grooved magazine may be inserted into the magazine opening 01 the firearm.
