Title: Improvements in the Breech Mechanism of Firearms.
Inventor: EICKHOFF THEODORE HENRY
IPC: F41A3/46
Filed: 1918-03-12
Abstract: 130,678. Eickhoff, T. H., and Payne, O. V. March 12, 1918. Machine guns; ordnance breech mechanism.- Relates to automatic guns of the kind described in Specification 14368/14, in which the breech block engages locking-surfaces inclined at such an angle that the breech remains locked under the high pressure immediately following the discharge, but opens when the pressure has fallen. According to the invention a transversely-sliding locking- member is mounted on the breech-block and is provided with inclined locking-lugs engaging the breech-body, the inclination of the lugs relative to the axis of the gun being less than the inclination of the bearing surfaces between the breechblock and the locking-member, so that backward pressure on the breech-block tends to unlock the locking-member except in the case of very high pressures. In the construction shown, a U. shaped locking member L slides in inclined grooves at the sides of the breech-block B, and has inclined locking lugs 10 adapted to engage recesses 11, Fig. 2, in the breech' body 5. The breech-block is moved forward and the locking member raised into the locking position by a single spring 1 and connecting link 2 acting on the locking member in an inclined direction.

Filed: 1930-02-14
Abstract: 333,500. Brancart, A. Feb. 23, 1929, [Convention date]. Rolling.-A process for cooling equally the two sides of a plate or sheet of glass, after it has been formed, consists in introducing between the glass and its support a metal rod to which a quick reciprocating motion is imparted. The rod loosens the glass from its support and permits air to penetrate beneath it, thus forming a gaseous cushion which insulates the sheet from the support and prevents it from cooling too rapidly. The rod may be hollow and perforated, and gas may be blown through the rod to supply the insulating cushion. The gas may be combustible and, by catching fire by contact with the glowing glass, help to keep the underside of the sheet hot. The apparatus may consist of two rods a coupled to one another by a link b and pivoted at c, so that they can oscillate in an horizontal plane and sweep over the surface of a receiving or casting table d.
