Description
United States Patent C UNDERWATER GUN John D. Koogle, Bellflower, Calif.
Application June 3, 1953, Serial No. 359,257
2 Claims. (Cl. 124-11) This invention relates to an underwater gun and has for its primary object to provide a gun of this character that has its projectile propelled by release of gas from a gas-filled cartridge.
More specifically, it is an object of the invention to employ a carbonio gas cartridge as the element for propelling the arrow or dart of an underwater gun.
Another object of the invention is to provide the novel combination of a carbonio gas cartridge, means to pierce the same and, thereby, to suddenly release the gas in said cartridge, and a gasketed projectile that receives the expanding force of said gas and is propelled thereby from the barrel of the gun in which the cartridge is placed.
The invention also has for its objects to provide such means that are positive in operation, convenient in use, easily installed in a working position and easily disconnected therefrom, economical of manufacture, relatively simple, and of general superiority and serviceability.
The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the drawing merely shows and the following description merely describes, one embodiment of the present invention, which is given by way of illustration or example only.
In the drawing, like reference characters designate similar parts in the several views.
Fig. l is a side elevational view of an underwater gun according to the present invention.
Fig. 2 is an enlarged longitudinal sectional view of the left end of the gun shown in Fig. l.
Figs. 3 and 4 are cross-sectional views as taken on the respective lines 3 3 and 4 4 of Fig. 2.
The gun that is illustrated comprises, generally, a barrel 5, a breech 6, longitudinally spaced hand grips 7 and 8, a trigger 9 carried by grip 8, a cartridge 10 containing carbonic gas and engaged by said trigger, means 11 to pierce said cartridge upon movement thereagainst by the trigger, a projectile 12 in the barrel and propelled by escaping expanding gas from the pierced cartridge, and means 13 to seal between said barrel and projectile.
Barrel comprises an elongated tube 14 of preferably round cross-section. Intermediate its length, said tube is provided with hand grip 7.
Breech 6 comprises a tubular member 15 to the forward end of which said barrel tube 14 is connected. An upper notch 16 in the breech affords access to the interior chamber 17 of the breech and is of sutlicient length to permit easy introduction of cartridge into chamber 17. The rearward end of tube is closed by a plug 18.
The hand grip 8 is shown' as integral with tube 15, although the same may be formed as a separate part attached to said tube. The forward face of said grip is provided with a recess 19 in which trigger 9 resides.
Said trigger 9 is shown as mounted on a pivot 20 and has a hand-pressing portion 21 residing in recess 19 and a cartridge-engaging portion 22 extending into chamber 17 of the breech. The latter portion is formed to partly encompass the rounded end 23 of said cartridge to retain the latter against accidental displacement from chamber 17. An expansion spring 24 between plug 18 and trigger portion 22 acts to urge the latter into lirm yet resilient engagement with cartridge 10.
The cartridge 10, as illustrated, is conventional of the type used for charging Water with carbonic gas, although the form thereof may vary. As shown, said cartridge is elongated and has a reduced end 25, opposed to rounded end 23, that is adapted to be pierced and, when pierced, effects release of the gas stored in said cartridge.
The means 11 is shown as a hardened fitting 26 carried by a wall 27 in the end of barrel tube 14 that is litted into breech tube 15. Said fitting is provided with a central bore 28 and with a sharp-pointed end 29 that is directed toward trigger portion 22 and punctures cartridge 10.
The projectile 12 is a generally conventional dart or arrow that is loosely fitted in barrel 5. The novel feature of said projectile resides in the sealing means 13 that comprises one or more O-rings 30 carried by the rear end of the projectile so as to seal between the latter and barrel 5. In order to minimize friction between O-rings 30 and the barrel wall, the former may be coated with a lubricant. Therefore, the effective range of the projectile is not unduly lessened by friction in the barrel.
In use, the cartridge is introduced through notch 16 into chamber 17 and the reduced end 25 of said cartridge is placed against sharp-pointed end 29 of fitting 26. The opposite rounded end 23 of said cartridge is then pressed against trigger portion 22 which retracts against the relatively light pressure of spring 24 and allows the cartridge to assume an aligned position in chamber 17. The pressure of spring 24, exerted through trigger portion 22, firmly holds the cartridge in place but with a resilient force that is too light to elfect puncturing of the cartridge by end 29.
The gun is operated by squeezing on hand grip 8 and trigger portion 21 to thereby force the cartridge in a forward direction and impale the end 25 of the latter on point 29. As the cartridge is punctured, the compressed gas stored therein is suddenly released, passes through bore 28 of fitting 26, and becomes effective on the adjacent end of projectile 12 to propel the latter outward from barrel 5. Since O-rings 30 provide against leakage loss, the full force of said gas is effective to propel the projectile. After expenditure of the gas as above, the empty cartridge is replaced by a full one and the gun is again ready to operate.
While I have illustrated and described what I now contemplate to be the best mode of carrying out my invention, the construction is, of course, subject to modification without departingfrom the spirit and scope of the invention. It is, therefore, not desired to restrict the invention to the particular form of construction illustrated and described, but to cover all modifications that may fall within the scope of the appended claims.
Having thus described the invention, what I claim and desire to be secured by Letters Patent is:
1. In combination, a gun having a breech provided with a chamber, a cartridge filled with expandable gas and occupying said chamber, an orificed sharp-pointed fitting engaged by a puncturable end of said cartridge and having its orice directed to open into said chamber, and means to press the cartridge against said fitting to puncture the same to release the gas in the cartridge and forwardly propel a projectile in said gun, said means including a trigger-mounted on a transverse pivot and provided with a portion embracing the end of the cartridge opposite the puncturable end thereof, and a spring in said breech normally holding said trigger in a first position against said cartridge to retain the latter 'against' said itting, said trigger being movable on its pivot to a second position to urge said cartridge forwardly f'or penetration by said oriced itting.
2..,In combination, a. gun having a. breech provided with a chamber andV a depending hand-gripping member formed with` a vertically extendingl forwardly facing recess, atcartridgelled with an.v expandable gasand occupyingv said chamber,A an oriced sharp-pointed tting: engaged by a puncturable end of saidi cartridgeY and4 having its orifice directed to open intoy said chamber, andmeans to press the cartridge against said tting to puncture the same to release the. gas in the cartridge andI forwardly propel a projectile insaid gun said. means comprising. a trigger pivoted between the walls dening said recess. to move relative; to the breech and provided with an extension contoured to snugly embrace the adjacent. end of the "urging sai'cl' trigger extension t'o lightly yet' `r'ml`y press the cartridge against the punefturing fitting.
