Description

Patented Feb. 4, 1939 GLADEON M. BARNES, OF HASTINGS, MICHIGAN ORIDNANCE No Drawing. Application filed August 22, 1927. Serial No. 214,792.
(GRANTED UNDER THE ACT OF MARCH 3, 1883, AS AMENDED APRIL 30, 1928; 370 0. G. 757) 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 ordnance and more particularly it has reference to composite barrels in which the liner may be readily removed.
Since the advent of high powder pressures and increased muzzle velocities all guns whether of the simple or composite type have been built from forgings. Latterly the development of a loose liner capable of expanding to and with the reinforcing tube without 5 exceeding its elastic limit has stressed the necessity for a material of a very high elastic limit.
I have discovered if a liner having an elastic limit of 65,000 pounds per square inch be overstrained 5% of its inner diameter it will possess a resistance which when used in conjunction with an outer tube of medium quality steel will provide a gun having the usual factor of safety.
This invention contemplates the employment of drawn seamless tubing of commercial production as a removable liner for guns. Where the tubing is of carbon steel I prefer to increase its resistance to pressure by overstraining the inner layers and I may likewise treat tubing of alloy steel for a similar reason. The outer tube may or may not be treated by overstraining.
I claim:
1. A gun including an elastic outer tube and a drawn seamless tubing freely insertable in said tube, said tubing having its inner layers permanently set by overstraining.
2. A gun comprising an elastic outer tube, a
drawn seamless inner tube having its inner layer permanently set by overstraining, the outer diameter of the inner tube being less than the inner diameter of the outer tube to establish a play space restorable after firing.
GLADEON M. BARNES.
