BREECH-ACTION FOE FIREARMS. I
Specification of Letters Patent.
Patented Mar, it this.
Application filed December 4,1911. Serial No. 663,912.
residing at Eltville-on-the-Rhine, Germany,
have invented certain new and useful Improved Breech Actions for Firearms, of which the following is a specification.
The present invention relates to a breechaction for automatic firearms and consists in the provision of a piston interposed between the breech bolt and its closing spring so that, by means of a liquid introduced between the bolt and the, piston the movement of the former can be transmitted to the latter.
In the accompanying drawings the invention is illustrated by way of example, Figure 1 representing a longitudinal central sec tional view of the lock portion of a gun, and Fig. 2 a cross-section on the line AB of Fig. 1. V
The breech bolt a, which contains the firing pin and its actuating spring, is slidably arranged in the breech casing (Z. This casing is double-walled and holds the breech bolt piston-like within the space inclosed by the inner wall. In the space between the walls a ring-shaped piston Z2 is arranged which is actuated by a spring 0. The spaces communicate with one another at the rear so that by means of a liquid, for instance glycerin, introduced into the inner casing between the bolt a and the piston b, the movement of the bolt can be communicated to the spring 0.
The casing (l isformed with a guide block 6 by means of which it is slidably held in the gun frame. A notch f in said block is normally engaged by a pivoted latch it which holds it in position. The latch is actuated by a spring and is fitted at opposite sides of the gun with cheeks z' by means of which it can be disengaged from the casing. When the latch is thus disengaged, th' casing can be removed together with the breech bolt so as to enable the barrel to be cleaned.
Suitable gripping surfaces are provided at the sides of the casing. The front end of the casing (Z joins at mzc a casing is which the casing (Z and which has its front end he at the opposite end holds the barrei. For
loading the barrel, the breech bolt a is tracted by means of a plate 12. which slides a nected to the bolt. proof closure of the ejecting apertureJf lVe claim This plate forms a (iii..mr-'
1. In a breech actionfor automatic'iire arms, the combination with a double-walied breech casing Whose chambers communicate with each ot er in therear, a slidable breech bolt in the inner chamber of said casing, and a springin the oiter chamber for holding said bolt inv closed position, of a piston an ranged in the outer chamber between the bolt and the spring so that, by means of a liquid introduced between the bolt and thepiston, the movement of the former can be communicated to the latter, substantially as setforth. g
2. In a breech action for automatic, fire arms, a double-walled breech casing, a
breech bolt fitted piston-like within the space inclosed by the inner wallof said casing, and a ring-shapedspring-actuated piston in the space between the walls, the spaces being in communication at the rear of the piston so that the movement ofthe bolt canbe transmitted by means of a liquid to the piston, substantially as set forth.
' 3. In a breech action for automatic fire arms, a double-walled breech casing slidably fitted by means of a-guide block in the gun frame so that it can be removed, a
spring-actuated latch pivoted to the gun frame and adapted to engage a notch in the casing for securing the latter in position, a
,breech bolt fitted piston-like within the space inclosed by the inner wall of said casing, and a ring-shaped spring-actuated piston in the space within the walls, the spaces being in communication at the rear of the piston so that the movements of the bolt can be transmitted by means of a liquid to the piston, substantially as set forth.
