2,126,816 55, including an oscillating-member having a transverse bearing-passage therein, a reciprocatable and tiltable member operatively connected to and both rocked and reciprocated by the pivotal movement of the said hammer and having sliding bearing in the bearing-passage in the said oscillating-member to effect the oscillation of the latter, and yielding spring-means actuated by the said oscillating-member and operatively interposed between the same and the said slidelocking member to shift the latter. 3. In a Slide-action firearm, the combination with the operating-slide, slide-locking member and firing-member thereof; of operating-means for causing said firing-member to shift the said Slide-locking member into and out of its slidelocking positions, the said operating-means including an oscillating-member, a reciprocatable and tiltable member operatively connected to and both rocked and reciprocated by the movement of the said firing-member and having sliding movement relative to the said oscillatingmember and coupled thereto for concurrent rocking movement therewith, and a spring-arm carried by the said oscillating-member and operatively connected to the said slide-locking member to shift the latter. 4. In a slide-action firearm, the combination with the operating-slide, slide-locking member and pivotal hammer thereof; of operating-means for causing said pivotal hammer to shift the said slide-locking member into and out of its slidelocking positions, the said operating-means including an oscillating-member having a transverse bearing-passage therein, a reciprocatable and tiltable member operatively connected to and both rocked and reciprocated by the pivotal movement of the said hammer and having sliding bearing in the bearing-passage in the said oscillating-member to effect the oscillation of the latter, and a spring-arm carried by the said oscillating-member and operatively connected to the said slide-rocking member to shift the latter. 5. In a Slide-action firearm, the combination with the operating-slide, slide-locking member and firing-member thereof; of operating-means for causing the said firing-member to shift the said slide-locking member into and out of its slide-locking positions, the said operating-means including a reciprocating-and-rocking plunger connected to the said firing-member, an oscillating-member oscillated by the said plunger, and yielding spring-means actuated by the said oscillating-member and directly interposed between the same and the said slide-locking members to shift the latter; and a firing-spring encircling the said plunger and thrusting against the said oscillating-member. 6. In a slide-action firearm, the combination with the operating-slide, slide-locking member and pivotal hammer thereof; of operating-means 5 for causing the said hammer to shift the said slide-locking member into and out of its slidelocking positions, the said operating-means including a plunger pivotally connected to the said hammer, an oscillating-member having a transverse bearing-passage therein slidably receiving a portion of the said plunger, and yielding springmeans actuated by the said oscillating-member and operatively interposed between the same and the said slide-locking member to shift the latter. 7. In a slide-action firearm, the combination with the operating-slide and slide-locking member and firing-member thereof; of operatingmeans for causing the said firing-member to shift the said slide-locking member into and out of its slide-locking positions, the said operatingmeans including a_ reciprocating-and-rocking plunger pivotally connected to the said firingmember, an oscillating-member having a transverse bearing-passage therein and slidably receiving a portion of the said plunger, and a spring-arm carried by the said oscillating-member and operatively connected to the said slidelocking member for shifting the same. 8. In a slide-action firearm, the combination with the operating-slide, slide-locking member and pivotal hammer thereof; of operating-means for causing the said hammer to shift the said slide-locking member into and out of its slidelocking positions, the said operating-means including a plunger pivotally connected to the said pivotal hammer, an oscillating-member having a transverse bearing-passage therein and slidably receiving a portion of the said plunger, and a spring-arm carried by the said oscillating- member and operatively connected to the said slide-locking member for shifting the same. 9. In a slide-action firearm, the combination with the operating-slide, slide-locking member and pivotal hammer thereof; of operating-means for causing the said pivotal hammer to shift the said slide-locking member into and out of its slide-locking position, the said operating-means including an oscillating-member having a transverse bearing-passage therethrough and journaled for oscillating movement in a portion of the firearm structure which is normally stationary, a reciprocating-and-tilting plunger pivotally connected to the said pivotal hammer and having sliding movement in the bearing-passage in the said oscillating-member to turn the said oscillating-member as the said pivotal hammer is swung, and yielding spring-means actuated by the said oscillating-member and operatively interposed between the same and the said slidelocking member to shift the latter; and a hammer-actuating spring encircling the said plunger at a point intermediate the said hammer and the said oscillating-member and thrusting against the said oscillating-member, WILLIAM C.
