摘要： A starter pistol for firing blank cartridges is generally in the shape of a typical medium duty upholstery stapler. A magazine having at least one chamber each holding a cartridge is fed into an open channel on the bottom of the device. A trigger is operatively connected to a firing pin and actuates the firing pin upon squeezing of a lever of the trigger by an operator. The trigger is also operatively connected to an advancement mechanism that advances each cartridge laden chamber into proper position for firing.

摘要： The invention concerns a handgun which comprises a trigger (42), a firing mechanism arranged to be actuated by the trigger and to fire a cartridge, a barrel (4) through which the bullet of the cartridge is projected when the cartridge is fired and a butt (60) which is arranged to be gripped in the hand of a user. The axis (57) of the barrel, and hence the line of action of a recoil force which is generated when the cartridge is fired, is at least substantially aligned with the line of action of a resisting force applied to the handgun by the use's hand. Also, the trigger is located above the axis of the barrel.

摘要： An actuator system for the trigger return in double-action revolvers includes an actuating rod having a rounded end engaged in a recess in the trigger with a helical coiled return spring biasing the rod by means of a cylindrical shoulder thereon and a rotary abutment member having a bore, which bore serves as a guide for the axially shiftable rod. The system provides an improved double-action operation since it compensates for the increasing reaction of the spring by reducing the lever arm or moment of this reaction on the trigger during its rearward movement. An improvement enables the user to control the "trigger weight" in a single-action operation by the provision of a return spring control bushing which can be adjustably threaded in the rotary abutment member to vary the effective operating length of the spring.
摘要翻译： 用于双动轮的扳机返回的致动器系统包括致动杆，该致动杆具有接合在触发器中的凹部中的圆形端部，其具有通过其上的圆柱形肩部偏压杆的螺旋形盘绕复位弹簧和具有 孔，该孔用作轴向可移动杆的引导件。 该系统提供改进的双作用操作，因为它通过在其向后运动期间通过减少杠杆臂或触发器上的该反应的力矩来补偿弹簧的反应增加。 一种改进使得用户能够通过设置一个回转弹簧控制套管来控制单次动作操作中的“扳机重量”，该回位弹簧控制衬套可以可调节地旋入旋转抵接构件以改变弹簧的有效操作长度。

摘要： A toy pistol has a hammer mechanism which includes a hammer lever controlled by a cam surface which cooperates with a nose portion on the trigger lever. The cam surface is formed on a separate member turning about the same fixed pivot as the hammer lever and is spring loaded by means of a light spring so that it normally rests against the front surface of the hammer lever adjacent the pivot, but is able to pivot freely away from the hammer lever against the effect of its spring, to permit the return movement of the trigger lever.

摘要： A removable trigger guard assembly for firearms which in its preferred embodiment includes the trigger guard having a trigger, a trigger spring, a cylinder actuating pawl, a hammer transfer bar and means for retaining the crane shaft mounted thereon. Means are provided for removably securing the trigger guard to the revolver frame, whereby the trigger guard and said connected elements can be removed from and returned to the revolver frame as a unit. The trigger guard has a key or insert connection at one end, preferably the front end and a releasable lug at the opposite end in resilient engagement with the revolver frame which can be depressed to release said engagement and remove the trigger guard assembly.
