    摘要： A pump action shotgun loaded from a magazine tube has a box magazine which feeds successive rounds of ammunition into the magazine tube through an opening in the side of the tube. Each successive round of ammunition is fed from the magazine tube into the receiver of the gun by a plunger connected by a rack and pinion mechanism to an action bar which moves the breech bolt between its retired and battery positions. The rack and pinion mechanism maintains the plunger out of the path of a round of ammunition fed into the magazine tube from the box magazine when the breech bolt is in its battery position and moves the plunger through a distance greater than the distance between the retired and battery positions to move a round of ammunition from the magazine tube into the receiver when the breech bolt moves from its battery to its retired position. The box magazine is adjustable to accommodate shells of differing lengths.

    摘要翻译： 从杂志管装载的泵动作霰弹枪具有盒式存储盒，其通过管侧的开口将连续的弹药进料到料仓管中。 每个连续的弹药通过由齿条和小齿轮机构连接的柱塞从杂志管进给到枪的接收器中，该作用杆将后膛螺栓在其退役和电池位置之间移动。 当后膛螺栓处于其电池位置时，齿条和小齿轮机构将柱塞保持在从盒式存储器馈送到弹匣管中的一圈弹药的路径中，并且使柱塞移动大于退役和 电池位置，当枪闩从其电池移动到其退出位置时，将弹药从杂志管移动到接收器中。 盒子可调节以适应不同长度的外壳。

    摘要： A shot-gun with gas take-off has a fore end stock which is movable longitudinally of the barrel and lockable selectively in each of two positions: in one position gases from the discharge of a cartridge in the gun bleed from the barrel into the chamber of a piston/cylinder unit to drive the piston to operate an arming rod of the shot gun automatically. In the other position, a valve member prevents the discharge gases from entering the cylinder chamber, these gases being vented to the external environment: the stock is rigidly locked to the piston for manual operation of the arming rod by "pump" action on the stock in the latter position.
