Abstract
A relatively simple repeating firearm is disclosed which includes a sliding bolt which is removably housed within a firearm housing and which is biased into a bullet loading and firing position by means of springs provided in an overlapping fashion with a longitudinal extent of the bolt to thereby reduce the overall length of the firearm. A short stroke for the sliding bolt is provided to enable a rapid firing of the firearm. The sliding bolt and firing mechanism contained thereon are easily removed from the housing by a removable rear cover with the firearm accommodating different calibers of bullets by replacement of the sliding bolt as well as a removable barrel which contains the firing chamber therein.
Claims41
A firearm comprising:
- a reciprocal sliding bolt;
- a housing comprising an interior open area, a firing chamber for holding a bullet for firing and positioned at one end of said open area, said open area having a portion thereof configured to guide a reciprocal path of movement of said sliding bolt forward towards said firing chamber and rearwardly away from said firing chamber, said sliding bolt loading a bullet into said firing chamber during said forward movement;
- a firing mechanism comprising a firing pin, first means for normally retractably biasing said firing pin within said sliding bolt during rearward and at least a substantial position of forward movement of said sliding bolt, and means for extending said firing pin from said housing to strike a rear of a bullet within said firing chamber, said means for extending comprising:
- a first member carried on said sliding bolt which is coupled to move said firing pin, a member supported by said housing and engaging with said first member at the termination of forward movement of said sliding bolt such that upon such engagement said first member moves to cause said firing pin to extend to fire a bullet, means for selectively moving said member supported by said housing to a first position where it is engageable with said first member and to a second position where it is not engageable with said first member, and a pivotal hammer having a rotation shaft fixed to a portion of said housing, said hammer being rotatable to a position for striking an end of said firing pin projecting from a rear side of said sliding bolt when said sliding bolt is at the termination of its forward movement to cause said firing pin to extend from said sliding bolt, whereby a bullet can be fired either by the engagement of said first member with said selectively movable member supported to said housing or by said hammer striking said end of said firing pin;
- and,
- second biasing means for biasing said sliding bolt forward toward said forward chamber.

- a housing comprising an interior open area, a firing chamber for holding a bullet for firing and positioned at one end of said open area, said open area having a portion thereof configured to guide a reciprocal path of movement of said sliding bolt forward towards said firing chamber and rearwardly away from said firing chamber, said sliding bolt loading a bullet into said firing chamber during said forward movement;
- a firing mechanism comprising a firing pin, first means for normally retractably biasing said firing pin within said sliding bolt during rearward and at least a substantial position of forward movement of said sliding bolt, and means for extending said firing pin from said housing to strike a bullet within said firing chamber when said sliding bolt is substantially at the termination of its forward movement, said means for extending comprising a first member carried on said sliding bolt which is coupled to said firing pin, and a selectively operable member supported by said housing and movable to a position engaging with said first member at the termination of forward movement of said sliding bolt such that upon such engagement said first member moves to cause said firing pin to extend from said sliding bolt whereby a bullet can be fired, said means for extending further comprising a pivotal hammer having a rotation shaft fixed to a portion of said housing, said hammer being rotatable to a position for striking an end of said firing pin projecting from a rear side of said sliding bolt, when said sliding bolt is at the termination of its forward movement, to cause said firing pin to extend from said sliding bolt, whereby a bullet can be fired either by the engagement of said first member with said selectively operable member or by pivoting movement of said hammer;
- and
- second biasing means for propelling said sliding bolt forward toward said firing chamber, said second biasing means engaging at one end with said sliding bolt at a forward portion thereof and at another end with said housing and extending along at least a portion of a longitudinal extend of said bolt.
