Abstract
Abstract A firing mechanism for a gun having a safety movable to a position which blocks the firing movement of the sear. The elements of the mechanism are generally coplanar and include a hammer pivotable in one direction to fire the gun and in the opposite direction for interengagement with the sear which holds the hammer in a cocked position. The hammer is also rectilinearly movable relative to its pivot point whereby the hammer may be moved into cocked interengagement with the sear while movement of the sear is blocked by the safety.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
Firing mechanism for a gun comprising a receiver, a trigger, a pivotal hammer, a sear releasably engageable with said hammer for retaining the same in cocked position and for releasing said hammer for firing the gun in response to trigger actuation, a safety movable to and from a position for blocking firing movement of said sear, said hammer being pivotable so that its sear engaging portion moves along an arc having a given radius of curvature, said hammer being rectilinearly movable to reduce said radius when the hammer being cocked engages said sear which is blocked by said safety, whereby the hammer may be swung into cocked engagement with the sear when the safety is positioned to block movement of said sear.
Claim 2
Dependent Claim
122 words
Firing mechanism for a gun comprising a receiver, a trigger, a pivotal hammer, a sear releasably engageable with said hammer for retaining the same in cocked position and for releasing said hammer for firing the gun in response to trigger actuation, a safety movable to and from a position for blocking firing movement of said sear, said hammer being pivotable so that its sear engaging portion moves along an arc having a given radius of curvature, said hammer being rectilinearly movable to reduce said radius when the hammer being cocked engages said sear which is blocked by said safety, whereby the hammer may be swung into cocked engagement with the sear when the safety is positioned to block movement of said sear.
Claim 3
Dependent Claim
58 words
Firing mechanism as set forth in claim 1 in which said hammer and sear are each provided with oppositely facing interengaging means, said hammer being pivotable about a pin disposed through a slot in said hammer elongated in a direction radially extending from said pin and spring means urging said pin toward the inner end of said slot.
Claim 4
Dependent Claim
67 words
Firing mechanism as set forth in claim 1 and including a linearly movable connector, said safety being pivotable for movement in generally coplanar relationship with said sear, hammer and connector, said safety including a portion linearly slidable on said receiver and a leg portion disposed to engage said sear for preventing firing movement thereof, said safety being urged outwardly of said receiver by a spring loaded ball.
Claim 5
Dependent Claim
56 words
Firing mechanism as set forth in claim 3 in which said connector is linearly movable to pivot said sear for firing movement thereof, said connector also being pivotable in response to pivotable movement of said hammer, said connector and hammer being adapted to enable said firing movement of the sear only when the hammer is cocked.
Claim 6
Dependent Claim
69 words
Firing mechanism as set forth in claim 4 in which said connector, hammer and sear are disposed in generally coplanar relationship, said trigger having means for imparting linear movement to said connector toward said sear for firing movement thereof, said sear having a recess disposed for accommodating the connector without sear actuation when the hammer is not cocked and for engagement with the connector when the hammer is cocked.
Claim 7
Dependent Claim
62 words
Firing mechanism as set forth in claim 5 further comprising a disconnector having a portion disposed to sense the position of the bolt of said gun and having means positioned to pivot said connector for non-engagement with the sear when the bolt is retracted, said hammer also having means to pivot said connector to a position for said non-engagement with said sear.
