Description
UNITED STATES PATENT- OFFICE. y
EUGENE w. THOMPSON, OF NEW'LONDON, CONNECTICUT.
FIEEABM.
` Application led J'une 15, 1915. \Seria 1No. 34,188.
To all whom t may concern:
Beit known that I, EUGENE W. THOMP- soN, a citizen of the United States, residing at New London, in the county of New Londonand State of Connecticut, have invented a new and useful Firearm; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to the art of fire arms and particularly to a Structure for lessening or overcoming the noise of the discharge of such devices.
A number of attempts have been made heretofore to eliminate and reduce the noise of the discharge of irearms. As a result of these attempts various devices have been attached at vthe end of the gun barrel, and in registration therewith, so as to distribute the .gases of explosion in various manners, or to dissipatethe energy of the gases, by
' imparting a rotary movement to them, in
order to overcome the noise. AS a further result of these attempts, independent chambers have been attached to the under side of the gun barrel, into which the gases are allowed to enter, .in such a manner as to break up the discharge of the gases, thereby reducing the noise. These and other devices of the Same character have been found more or less ineiicient.
Therefore it is the object of the invention to overcomesuch ineiicient constructions, and produce a deviceof this I ind, .in which novel features of construction are involved.
It has been found that a projectile receives its greatest force instantly subsequently to the explosion, therefore a gun barrel has been produced having a short smoothbore surrounding the projectile at n, thereby avoiding a.v smooth bore of the full length of the barrel, 'and in which barrel beyond the short smooth bore the various parts of thesilencer are arranged. c
lIn the drawings -Figur'e 1 is, a long1tudinal sectional view through the entire length of a gun barrel,'showing a portion of the,
breech with the perforated .spools and rings arranged alternately therein. Fig. 2 1s a.
perspective view of one of the perforatedspools. Fig. 3 is a detail perspectlve viewof one of the rings.
Referring more partlcularly to the draw- Specication of Letters Patent.
A having a bore therein, a plurality of spool Patented Feb. 29, 1916.
ings 1 designates the gun barrel while 2 denotes the breech portion thereof, in the bore 3 of which the cartridge l is arranged for explosion.
v It' has been found that, it is only necessary to construct the bore 3 substantially twice the length of the cartridge, for the projectile receives its greatest force instantly after or substantially at the time of the explosion. The wall of the barrel of the gun beyond the breech 2 is much thinner than the walls surrounding the bore of the breech and is tapering to the outer end of the gun barrel. Arranged in the bore 5 beyond the breech is a plurality of spool shaped members 6 arranged axially, and each disposed alternately with relation to rings 7. These rings are in the form of annular bands. The spool shaped members comprise the bodies 8 having the annular :Hange's 9 at their ends. VThe bodies 8 and the flanges 9 are perforated, as shown at 10 and 11. By placing the rings between the spool shaped members chambers 12 are provided the diameter of which are less than the chambers 13 surrounding the bodies 8 of the spool shaped members. The gases following the projectilethrough the bore 14 of the spool shaped members pass through the perforations, and in and out ofthe chambers 12 and '13, thereby scattering the gases, which lessens and overcomes the noise incident to th discharge. Threaded or otherwise secured in the outer end of the gun barrel is a cap or plug 15, between which and the shoulder 16 at the breech end of the gun barrel, the various spool shaped members 6 and the rings 7 are clamped.
From the foregoing it will be observed, there has been devised a novel silencer for fire arms, and one which has been found to effectively and efficiently overcome the noise incident to the discharge, and in a practical manner.
The invention having been set forth what is claimed as -new and useful is 1. In combination with a gun barrel having a bore therein with a shoulder at'one end and a plug secured therein at the other end, a plurality of spool shaped members and rings arranged in the gun barrel, each alternately with the other between the shoulder and the plug. Y
2. In combination with a fire arm barrel shaped members and rings,` each disposed alternately with the other and clamped yin the bore,'thereby forming chambers a part of the length of the barrel.
3. In combination with a fire arm barrel having a bore therein, a plurality of spool shaped members and rings, each disposed alternately with the other and clamped in the bore, thereby forming chambers a part of t-he length of the barrel, the spool shaped members having annular perforated flanges at each end, thereby permitting the gases to pass in and out of the `chambers.
4:. In combination withY a fire arm barrel having a bore therein, a plurality of spool shaped members and rings;L each disposed alternately with the other and clamped in the bore, therebyforming chambers a part of the length of the barrel, the spool shaped members being entirely perforated and having annular flanges at each end, thereby permitting the gases to pass in and out of the chambers. r
5. A lire arm barrel, a plurality of spool shaped cylindrical members and rings disposed therein alternately With each other substantially the full length of the bore of the barrel, and being clamped at each end of said bore.
In testimony whereof I have signed my name to this specification in the presence of two subscriblng witnesses.
EDWARD Si. NEILAN, ARTHUR T. KEEFE.
