Abstract
An automatic pistol adapted to repetitively fire blank ammunition includes a frame, a barrel unit supported by the frame and a slide unit reciprocally mounted on the frame between the forward and rear position. The barrel unit and/or frame incorporate structure which enables the pistol to operate in a highly reliable, repetitive manner without visible alteration to the pistol. A method for forming a blank firing pistol is also disclosed.
Claims25
An automatic pistol for firing blank ammunition, which comprises:
- a frame;
- a barrel unit including a barrel chamber portion and a generally cylindrically shaped barrel element extending from said barrel chamber portion;
- a slide mounted on said frame and adapted for reciprocal longitudinal movement relative thereto between a forward battery position and a rearward position;
- means for constricting the diameter of the bore of said barrel element, said constricting means dimensioned and configured to generate sufficient back pressure in said barrel unit upon firing of a blank cartridge to move said slide to said rearward position;
- a slide bushing member mounted to a forward end portion of said slide for reception of a forward end portion of said barrel element;
- and
- an engaging member positioned about said barrel element for driving said barrel unit rearwardly during rearward movement of said slide to a loading position wherein a blank cartridge is loaded within said barrel chamber portion of said barrel unit.

A firearm for firing blank ammunition, which comprises:
- a frame;
- a barrel unit including a barrel chamber portion, a barrel element extending from said barrel chamber portion and a barrel linkage housing extending downwardly from said barrel chamber portion;
- a slide mounted on said frame and adapted for reciprocal longitudinal movement relative thereto between a forward battery position and a rearward position;
- a slide bushing member mounted to a forward end potion of said slide for reception of a forward end portion of said barrel element;
- a second bushing member positioned about said barrel element and secured to said barrel element at a position adjacent said barrel chamber portion, said second bushing member dimensioned and configured to be engaged by said slide bushing member upon movement of said slide to said rearward position thereof to drive said barrel unit rearwardly to receive a blank cartridge, said second bushing member dimensioned and positioned to permit rearward movement of said slide a predetermined distance prior to engagement of said second bushing member with said slide bushing member;
- and
- a detent mechanism associated with said barrel unit and operatively engagable with said frame, said detent mechanism including a contacting member mounted with respect to said barrel linkage housing and engagable with one of said frame and said barrel linkage housing, said contacting member dimensioned and configured to resist movement of said barrel unit from said loading position during loading of a live blank cartridge through frictional contact of said contacting member with said one of said frame and said barrel linkage housing.

An automatic pistol for firing blank ammunition, which comprises:
- a frame;
- a barrel unit including a barrel chamber portion, a barrel element extending from said barrel chamber portion and a barrel linkage housing extending downwardly from said barrel chamber portion, said modified barrel connected to said frame by a pivotal connecting link connected to said barrel linkage housing;
- a slide mounted on said frame and adapted for reciprocal longitudinal movement relative thereto between a forward battery position and a rearward position;
- a slide bushing member mounted to a forward end portion of said slide for reception of a forward end of said barrel element;
- a second bushing member associated with said slide bushing member and extending rearwardly from said slide bushing member, said second bushing member dimensioned to engage an abutment surface of said barrel unit during movement of said slide to said rearward position to drive said barrel unit rearwardly to a position to receive a blank cartridge, said second bushing member dimensioned and positioned to permit rearward movement of said slide a predetermined distance prior to engagement of said second bushing member with said abutment surface of said barrel unit;
- and
- a detent mechanism associated with said barrel unit and operatively engagable with said frame, said detent mechanism including a contacting member mounted with respect to said barrel linkage housing and engagable with one of said frame and said barrel linkage housing, said contacting member dimensioned and configured to resist movement of said barrel unit from said loading position during loading of a live blank cartridge through frictional contact of said contacting member with said one of said frame and said barrel linkage housing.
