Abstract
704,837. Firearms. OLIN INDUSTRIES, Inc. Dec. 1, 1952 [Dec. 18, 1951; Dec. 18, 1951]. No. 30434/52. Class 119 A firearm comprises a chamber member 2, in connection with a receiver 1, constructed to contain the explosive force of the round to be fired independently of the barrel 4, the barrel being mounted over the chamber member and connected thereto, and the chamber member having a neck portion 10 which can expand into sealing contact with the barrel under the pressure of the explosion. In one construction the chamber member 2 is secured to the receiver 1 by an interrupted-screw portion 8, and is screw-threaded at 3 for the connection of the barrel 4. A flange 6 on the member 2 provides abutment faces for the receiver and barrel. The member 2 is of high strength metal, such as nickel steel, nickel-vanadium steel, stainless steel, or beryllium-copper alloy so that it can withstand, without rupturing, the gas pressure developed on firing. The neck portion 10 is thin-walled so that it expands on firing into sealing contact with the barrel. The barrel is of light material such as aluminium alloy, magnesium alloy, or titanium and its alloys. As an example a barrel of aluminium alloy has an outer and inner coating of pure aluminium, and this may be anodized both inside and outside. In a modification, Fig. 3 (not shown) the chamber is integral with the receiver and has half-threads for the connection of the barrel which, when in place, is secured to the receiver by a set. screw. In another construction, Fig. 4 (not shown) fine full screw threads connect the chamber to the receiver, and half threads connect the barrel to the chamber.
