integral loop-like trigger-guard 2| and with a central-longitudinal mechanism-receiving channel 22 opening upwardly through the upper surface of the trigger-plate substantially throughout the major portion of the length thereof and at its rear end intersecting the space circumscribed by the loop-like trigger-guard 2|. The forward portion of the said mechanism-receiving channel 22 is closed at its lower end by a bottom-wall 23 formed integral with the triggerplate 20.

Extending transversely across the forward Aportion of the mechanism-receiving channel 22 and the trigger-plate 20, is a pivot-pin 24 upon which is pivoted a hammer 25, the upper portion of the forward face of which is adapted to strike a firing-plunger or other suitable firing-member which is indicated by the broken lines 26 in Fig. 1.

Pivotally connected by means of a pivot-pin 21 to the rear portion of the hammer 25 is the forward d'or head-end 28 of a rocking and reciprocating hammer-actuating plunger generally designated by the reference character 29. The said plunger 29 also includes va rearwardly-extending cylindrically-contoured shank 30 freely movable in a passage 3| formed in a bridge portion 32 extending across the mechanism-receiving channel 22 in the trigger-plate 20 about midway the length thereof and forming a rigid feature of the said trigger-plate. I'hrusting Vforwardly against a rearwardly-facing thrust-shoulder 33 formed on theplunger 29 at the junction of the head-end 28 and the shank 3U thereof, is the forward end of a helicalhammer-spring 34 encircling the said shank 30 and pressing at its rear end against the front face of the bridge portion 32 of the trigger-plate 20. As thus arranged, the hammer-spring 34 exerts a constant effort to swing the hammer 25 in a; clockwise direction to cause the same to strike the firing-plunger 26 (Fig. 1). l

In its lower portion the hammer 25 is formed with a cocking-,abutment 35 which is releasably engageable by the forward face of a Sear-nose 36 constituting theforwardly-extendin'g arm of a pivotal sear 31. The said sear 31 is located in the mechanism-receiving channel 22 of the trigger-plate 20 and is pivotally mounted therein about midway of its length upon a pivot-pin 38 extending transversely across the said channel 22. Pressing upwardly uponthe scar-nose 36 of the sear 31 so as to yieldinglyvhold the said searnose in position for engagement with the cocking-abutment 35 oi' the hammer 25, is a helical Sear-spring 39 seated at itslower endin an upwardly-opening spring-pocket 40 formed in the upper surface ofthe bottom-wall 23 of the trigger-plate 20, as is shown in Fig. 1.

In addition to its ,forwardly-extending searnose 36, the sear 31 is formed with a rearwardlyprojecting am 4| having its rear portion normally resting upon an upwardly-facing actuatingabutment `formed at the forward end of a. pivotal transmitting-member 43. tion of the transmitting-member 43. just referred to is mounted for pivotal movement upon a pivotpin 44 extending transversely across the upper rear portion of the mechanism-receiving channel 22 in the trigger-plate 20.

vThe main portion of the transmitting-member -43 extends in and Athrough, a longitudinal channel 45 formed in a trigger 46 and opening through v the under face lof the said trigger adjacent the forward end thereof. The said trigger is mounted The upper rearporat its forward end for pivotal movement in the mechanism-receiving channel 22 in the triggerplate 20, by means of a transverse pivot-pin 41 as is4 shown in Fig. 1. The bottom wall of the channel 45 in the trigger 46 is adapted to engage with a transmitting-lug 48 depending from the transmitting-member 43 about midway the length thereof.

The trigger 46 is provided at its rear with a rearwardly-and-downwardly-curved finger-piece 49 projecting into position for engagement by the nger of a marksman inserted through the trigger-guard 2|. The saidv trigger 46 is also formed with a rearwardly-extending integral stop-finger 50 which is adapted to cooperate with a safetyslide 5|, in a manner as will hereinafter appear.

The safety-slide 5| above referred to is of cylindrical form generally, and is mounted for both reciprocation and oscillation in a cylindricallycontoured guideway 52 extending transversely across the trigger-plate 20 adjacent the rear portion of the trigger-guard 2| and adjacent the stop-finger 50 of the trigger 46. The forward portion ofthe transverse guideway 52 intersects or breaks through," so to speak, a continuation 22a of the mechanism-receiving channel 22 and which opens into the space enclosed by the trigger-guard and the adjacent portions of the trigger-plate 20 proper, as is especially well apparent in Fig. 8. l

Each of the respective opposite ends of the safety-slide 5| is preferably knurled or otherwise roughened to provide an anti-slip surface for the finger of the user of the firearm in which the present invention is incorporated, and one of the said ends is formed with a diametrical slot or kerf 53 designed for the reception of a coin orscrewdriver in a manner and for the purpose as will hereinafter appear. y About midway ,between its respective opposite ends, the safety-slide 5| is formed with a clearance-notch 54 which is slightly wider than the width of the stop-finger 50 of the trigger 46, and which is adapted to freely receive the said stop-finger when the safety-slide 5| is in all save one of its three different positions, as will hereinafter appear. l

The safety-slide 5| is adapted to assume three different positions as will more fully appear from the following, one normal position (Figs. 2 and `3) in which the safety-slide permits the free unhindered operation of the trigger 46 to effect the release of the hammer 25 and which position, for convenience ci' description, will be referred to herein'as the normal firing position." and from which position the safety-slide is readily shiftable by an axial movement thereof.

Another position which the safety-slide 5| may assume, is a positiongin which it permits the free movement of the trigger but from which it cannot vbe readily shifted save by a Special unlocking movement of the said safety-slide. This latter position will, for convenience of description. be designated as the "locked nring position and itis the position in which the said safety-slide is shown in Figs. 6, 7 ands.

I'he third position into which the safety-slide 5| is adapted to be moved, is one in which its clearance-notch 54 is moved out'of full registration with the stop-finger 50 of the trigger 46, and in which position the said safety-slide prevents the normal full releasing movement of the trigger 46, as is illustrated in Figs. 4 and 5. The position of the safety-slide 5| as just referred to, will,
