" HENRYB. FEBIGER, 01 NEW ORLEANS, LOUISIANA.

To all whom it may concern the following is a specification. 'Th1s invention, relates to a device of the samegeneral character as that illustrated in my Patent, No. 908,553, of January 5, 1909; and I herein describe and claim one feature which was illustrated and described therein but which was not claimed therein, namely, the locking of the safety slide during thefiringoperation, p p p One purpose of my invention is to snn-' 'plify and strengthen the auxiliary sear for the hammer when the trigger is drawn back.

.A further purpose of my invention is to cause the auxiliary sear to engage preferably with the same notch of the hammerv as the. trigger sear. z

\-;t'urthe|.' purpose of my invention is to provide a plurality of sears, oneofwhich is automatic when the trigger is drawn back- .ward, and means for disengaging the automatic; sear under certain circumstances.

A further purpose of my invention is to. provide for thevplaeing of the automatic sear for engagement with the hammer when the trigger 1s=drawn on the under side of the hammer, leaving the rear of the hammer \\'ltl10l.1t complicationthereby,

A- further purpose of" my nvention is to "provide a trigger pull in an automatic 'gun which'shall innncdiatel release from the I hammer withont'any drag"or loss of motion. p p

A further purpose of my invention direct and positive movementof the. seat-engaging the hammer notch with movementof'the trigger in an automatic loadinggun movement.

"it furtherpurposc of my invention is to "provide forthe-lockingof the safety slide in an automatic loading gun during the tiring operation to prevent arring of'the safety slide to safety position.

it further consists of othernovel features of construction, all as will. be hereinafter fully set torth.

For the purpose ot illustrating my invention, l have shown in the accompanying drawings some forms thereof which are at present preferred by me,

since the same have been found in practice to give satis'tactory is to MOVEMENT Fon'rmEAnMs.

and reliable results, although it is to be understood that the Various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 is a longitudinal section through a portion of an automatic loading gun frame with the parts in safety position and the hammer cocked. Fig. 2 is a section 'similar to Fig. 1 with the parts in firing position. Fig. 3 is a perspective of certain operative parts in detached position. Fig. 4 is a perspect-ive of the same partsv assembled and from another view point. Fig. 5 is a plan partly in section of some of the par-ts involved in my invention; Fig. dis a perspective of a safety slide latch illustrated by me. Figs. 7 and 8 are broken end elevations of modified forms of the elen'ients in Fig.

Similar nume'als of f-reterence indicate corresponding parts in the figures.

Referring to the drawings :1 designates a frame having upper and lower tangs 2 and 3, stock assembling screw 4 and trigger guard Within this portion of the frame 1 have illust rated a well known hammer 6 pivoted at G and main spring rod 7, operating spring-8, collar 9 and pin 10, comprising the hammer and operating mechanism pressing forwardly at all times and driving it against the firing pin not shown. In Fi 2 this rod is broken away to vshow a preferably central slot 11, through which passes the trigger spring post. l2, connecting with the upper part t3 of the triggerspring post, about which is coiled the trigger spring 14, bea ring on plate which is a perture'rt at 16 and slotted at. it) to permit the rod to pass through it and toact'. as a. guide. Thisplate )erforms the function of affording a bearing for theupper art of the trigger spring, a uide for the tepending portion of the safety slide 17 which-is retained therein by pin IS-and also affords-a spring; latch 19 for the safety slide l7-titting into the notches 20 or 2L according to the position ofthe safetyslideand being given its spring pressure by means of the spring 14. 'lheforward end of the safety slide is, additionallyguided and rctai'nedliy a pin-.22operating in a groove 21). The depending portions 24: and

A l of the safety slide. operate within a slot 25 in the upper tang, the center of this slot lit) gr-r sear, either actually, where the being of a diameter suflieient to accommodate the trigger spring post 13.

The lower portion of the trigger spring post is preferably flattened because of the desirability of having it pass through the rod 7 so that both of them may be central,

and is desirably notched at 26 to bear in this form upon a laterally projecting extension 27 from the end of the trigger E28, carrying scar 28. The extension is shown in the form of a pin secured thereto or integ'al therewith. The major portion of the space 29, where it cuts the lower tang, giving room laterally atone point for the auxiliary sear release lever 30, pivoted upon pin 30 or other suitable support, and the auxiliary sear 31 engaging therewith. The end 32 of the trigger is shown as even with or projecting above the projection 27 through a portion of its width at 3 1; and as slotted or notched at 33 througllout the remaining portion 'of its width to provide a seat for ap' proximately half of the width of the lower portion of the trigger spring post in order that this trigg er spring post may be central throu hout, this being the preferred form, thoug i evidently it could be accommodated at this point in other ways.

The auxiliary sear release lever 30 lying with its end 35 preferably wholly below the projection 27 does not interfere in an y vay with the seat. of the lower end of the trigger spring post and need not be notched for this reason, notwithstanding that, it. preferably lies near the trigger. 1t should be noted at this point that the auxiliary sear release lever does not, engage the lower side of the projection 27 at all times, as for example, in the position shown in Fig. 2.

The trigger is apcrturcd at 256 to pivot about any suitable pin 37 which affords pivotal support also in the form illustrated, though evidently not essentially for the auxiliary sear 31, the trigger and sear preferably, as stated, occupying approximately the entire width of the space within the tang. The auxiliary sear 31. is provided with a. lever end 38 upon the opposite side of the pin 37, as -shown in dotted lines in Figs. l and 2, for engagement by the end 39 of the auxiliary sear release lever 30 so that downward movement of the end 35 of this release lever 30 will result in disengagement of the auxiliary sear from the hammer notch 40, this hammer notch preferably extending clear across the hammer for engagement at will with the auxiliary scar and trigger sear, though evidently two notches extending each part way across the hammer at couwnient points would accomplish the same purpose. The single notch across the hammer siinplities the construction and op oration. lu eilher event the auxiliary sear CH. is placed slightly in advance of the trigsingle hammer notch is used or relatively with respect to the position of the notches if a plurality of notches are used. The auxiliary sear is normally pressed against the edge of the hammer to drag thereon when the tri ger is drawn haekwardly by any suitab e means such as a spring -l-l which is shown as pressing against the end 35) of said scar and which is held to its duty in the form illustrated by means of sc1e\ The trigger 28 is limited in its movement by an an'ljustable stop 43 here shown as screwed to place through the trigger guard,

It will be evident that the adjustment of this screw detern'iincs not only the limit of movement of the trigger itself but the greatest height to which the trigger spring post is raised by means of the rear end of the trigger 32 and therefore controls also the distance to which the end 44 of this trigger spring post will extend within or through the aperture 45 in the safety slide 17.

In operation it will be evident that the trigger -annot be pressed without the end of the trigger spring post passing into the a el" ture 45 in the safety slide and that this side in the position shown in Fi forms a complete stop to movement of the trigger and, correspondingly, to disengagement of the trigger scar from its hammer notch. It will be equally evident also that the'salety slide cannot be moved at all while the trigger spring post is engaged within the aperture 1-5 and that this engagement can be timed to begin as soon as the tri ger has moved at alhand, therefore, thatit is 1, therefore merely a matter of dimensioning the trigger v and spring post to determine that the safety slide shall be incapable of movement except when the trigger is in its forwardmost position. The safety slide is also guarded against accidental movement or any 'movement from its extreme positions except under pressure by means of the engagement of the latch 1!) spring pressed within the notches 20 and 21 by means of the spring 14.

la the position shown in Fig. 1 the trigger sear 2a is shown in engagcmentwith the notch -10, being pressed therein by the lower end of the triggcrspring post which is spring pre sed against the opposite end 32 of the trigger. This is the position of the parts which would be assumed if the hammer were rocked manually, the trigger sear being the earlier of the two scars to engage with its notch and. when set. preventing engagement of the auxiliary sear with its notch as herein indicated. This is. the only latch which would be required with other than an automatic gun. the auxiliary scar and mechanism relating thereto being intended to take care of the automatic cooking of the hammer. while the tri ft'u' is held in retracted position, such as illustrated in Fig. 2 to pro vide for retention of the hammer in its posi- "triggerspring; postyto efl'ect'the same result,

It will now be apparent that I have de vised a novel and useful construction of a fire arm which embodies the features of ad- 'vantage enumerated as desirable in the statement of the invcntionand the above description, and while I have in the present instance shown embodiment thereof which has been found in practice to give salislzn'tory and reliable results, it is to bc lllll'ltlslontl that the same is susceptible of nimlilication'in various particulars without departing or scopeof the invention or sacrificing any of its advantages.
