Fig. 9 is a simila view to Fig. 8, but the section is taken on the line at. Fi .-3; the parts of the firing mechanism there by illustrated being shown in the positions .they assume after a discharge and while fingerpressure is still being exerted upon thetrigger. Figs. lqand 11 are two further enlarged sections, taken respectively upon the dotted lines a and as", Fig. 1

throughjthe dovetailed and interlocking parts of barrel, breech-slide and body. Fig. 12 is another cross-section'of Fig. 1, taken u on the dotted line at. Fig. 13 shows an e evation and end view and an underside plan of the barrel se arately. Fig. 14 shows an elevation and p an of the breech slide separately. Fig: 15 is a se a'rate elevation and front end view of-the body. Figs. 16

and-- 17 are detail parts of the firing mechanism;

The samele tters of reference indicate corresponding parts in the several figures of the drawing.

a is the body or frame of the pistol and a thehandle or grip, which is adapted to cohtaiira detachable magazine.

'. b is the barrel, Whose breech portion has a dovetail or inverted-T sectioned base b which is engaged with an o en-ended channel or seating a of correspon in section in the forward part of the body, wh e normally the said barrel and bod T are immovably locked together by any suitable fastening, such as the combined trigger-guard and bolt b although when the said fastening is disengaged, the barrel may be dismounted by sliding the same forwardly oil the body in the usualway. a i

' c is the breech-slide, which is slidably and detachably' mounted upon the rear of the said body, and is secured thereto, in the known manner, bymeans of'st'raight ribs or feathers c en 'a in under corres ondin b b ribs w that are formed from end to end of the opposite sides of the body, while inorder to carry the stops which limit the rearward or recoiling movement. of the breech-slide and to simplify the construction while admitting of the dovetailing and interlocking of t 1e said reech slide is provided, under the pres ent invention, with a. pair of laterally-Se a-- rated cheeks or extension pieces'c",'c,- which closely embrace theopposite sides of both the breech part of the barrel and the forward ortion of the body, and are of sutlicient ength to admitof the prescribed recoiling movement of the breech slide ythe said movement being limited by means of stops c, e, which are arranged on the inner sides of the forward extremities of the said extensions and are adapted to cooperate with corarts (1, b and c, the forward end of the after the iii-st discharge.

responding stops or shoulders 1)", 5 on the rear or breech endv of'the lmrrel. These stops are so formed and arrangedthat, whenv which are formed below the said ribs a and 7 from end to end of the opposite sides of the body, while when the breech slide is in motion, the said ribs c, c, of the extensions traverse to and fro-within the said race-ways. From the above-described arrangement it results that the body has interlocking engage ment, by virtue of the dovetailed part-s both with the barrel andthe breech slide andits extensions,fbut in order-to complete their.-

terlockingsystem and to .laterally tie. or brace together the said extensions soas to prevent them spreading, the opposite sides of the breech-portion b of the said barrel are formed with recessesor clearances b which are engaged by the extensions 1:, .c and their stops 0, c and terminate rearwardly' at the barrel stops b, N, while. the top edges of the said extensions and the overhanging parts I) of the barrel are d0vetailed,.as' shown in the'enlarged sections. Thus the breech slide extensions are dovetailed to the'body by the ribs a and race-ways a and'to' the barrel by the parts b, and 'as the body and barrel are also dovetail keyed to one, another as above described, it follows that all the;

parts mutually support one another and are thereby enabled to effectually resist the strains to which they are subjected on the pistolbeing discharged and during the re coiling; and return movements of the breech slide following each. discharge. 5 And when the breech slide is at the limit of its rearwa'rd movement, as determined by the stops, the laterally-separated extensions 0, 0 move from underneath the overhanging-parts of the barrel, as shown in lfigt-t, and an open- 1v mg or clearance .ispresented wherethrough;

the spent cartridge-Shellie ejected prior to?" the said slide commencing its return or closing movement.

WVith regard to the firing mechanism with which the body is fitted; this consists of a minimum number of simple parts, but is positive in action and provides effectually against inadvertent discharges or unintentional second, shots in the event of fingee pressure, being maintained on the trigger Thus the hammer eand its spring e and the. sear f and its I a ina-f, are

arranged, in, substantially the ua ma ne and behind the magazine-containing handle, while the trigger g and its springg are "fitted fin firont f the said handle, also in the known manner'.. The connection between the -trigger. and the searfis, however, effected in a ovel manner'by provid ng the sear with a rigid limb or bar h, which is also nfluenced by the sear spring and is. extended across one 1 "side of the handle frame so that its forward.

On being thus d sengaged from thehammer,

" the combined or oneepiece sear and limb are moinentarily shifted, by'the spring to the position shown in Fig. 2 in which the forward'e'xtremity or the said limb is below the contact stud, but the recoiling breech-slide immediately recocks the hammertsee Fig. 3) and brings back thecombined scar and limb tothefull-cockposition Fig. 1. Dur-- ing this re-cocking a'ctlon, the trigger is held back by the pressure of'the -shooters finger in the position shown in Fig. 3, and in order to render it impossible for any operative connection between trigger and. sear to be reestablished until the trigger has been first allowed to. resume the normal (Fig. 1) position, and thus effectually guard against in advertent ordouble shots, the inner side of the forward extremity of the limb-is formed with a cam or incline j which, in course of the upward angular movement-which the limb 7 makes under. the influence ofthe sear-spring on the hammer being recocked- (t; e. in
