To all whom may concern:

Be it known that I, ALLAN W. Woonnnrr,

a citizen of the United States, residing at Chicago,-in the countyof Cook andState of Illinois, have invented new and useful Improvenients in Firearms, of which the following is a specification.

This invention While primarily intended for application to single-barrel'shot-.guns, yet, as will hereinafter appear, the mechanism is applicable, with but slight modification, torifles, `double barreled and magazineguns, so that I am not to be understood as beinglimited in this respect.

The principal objects of my invention are to simplify and reduce'the number of parts usually employed in gun mechanisms, and thereby materially reduce the cost of manufacture; to obviate the necessity of employing numerous small parts that are given to wear and brealiage, whereby the upkeep is negligible; and finally, to so construct a gun that it is always safe except at the moment of firing, thereby rendering accidents less liable and also greatly increasing the life of lche main-spring by placing the same under tension only at such times as the gun is ready foidischarge.

Other objects and advantages of the invention will hereinafter appear, and the novelfeatures of thesame will be particulai'lydescribed and pointed out in the claims.

Referring to the drawings:

Similar numerals of reference indicate similar parts in all the gures of the drawings.

It will be understood that the barrel 1, and the forearm 2, are of the conventional style and constitute no part of my present invention. The barrel is preferably formed with the top rib-extension 3, terminating in this instance in the usual doll-head. The rear end of the extension is provided with a shallow cavity 4, for engagement with the toplocking bolt `hereinafter `referred to. The stock 5 has its grip G longitudinally recessed, as at 7, to receive certain parts of the lock-mechanism and is joined to the receiver or frame in the usual manner.

For convenience and strength, the receiver or frame is formed of a single casting, the upper part ofthe rear face of which is pro- .vided with a socket 8, into which fits a tenon 9, formed at the forward end of the top `cover-plate 10, (see Figs. 9 and 10,) that closes the upper side of the recess 7 of the The rear end of this top cover-plate extends beyond the end of the recess 7 of the stock and may be perforated to `receive a screw 11, which passes therethrough and into the stock. By removing the screw it will be evident that ,the cover-plate may then be withdrawn rearwardly from its engagement with the receiver or frame and thus access `may be obtained tothe lock-mechanism within.

In advance of the tenon 9 of the coverplate, the receiver or frameis provided near its upper side with a longitudinal bore 12,

.which latter near its front end is reduced as `at 13, the two bores being in line with the shallow locking cavity 4. of the eXtension- .rib of the barrel. These bores are further continued in the upper side of the tenon 9 of the cover-plate, saidtenon being bored, as at 11, for the purpose. The groove 14: is

not so deen as is the groove 12 with which it communicates, so that the front end of the tenon 9 forms a shoulder 15.

In the groove 14 and the bores 12 and 18 is mounted for reciprocation to a limited ex- 8,) the front end ofwhichj bolt is reduced,

as at 17, to correspond to the reducedfborev 13, beyond thek front end of which bore said bolt slightly projects,ris beveled, andis. adaptedfto4 engage the cavity '4 of thel barrel extension whenthe latter is closed, whereby the said barrel becomes locked against opening. l

Betweenitsmiddle and rear end, the locking-bolt is reduced, as'at '18, such reduced portion forminga4 front shoulder, 16a, the redued'port'ion being occupied by a light coiledspring f1.9, they frontend of which bears against 'the Shoulder 16a and the rear end of whichbears vagainst the shoulder 15 of the tenon9, whereby the locking-bolt is normally forced forward to eli'ect `a locking engagement with the barrel and thus retain the lattericlosed.y The rear end kof the top locking-bolt projects beyondv the receiver and may' be fashioned with `an enlarged milled head 20, readily adapted to be en-V gaged by the thumb of the user so that the bolt may be withdrawn to disengage it from the barrel `and permit the latter to open. The barrel, it Vwill be understood, has its extension 55, hinged in the usual manner, at 21, to the front extension of the receiver or frame, and when released as described lfrom its engagement with the top locking-bolt, the barrel maybe opened in the usual Inanner for the purpose of withdrawing or ejecting the empty shell and reloading the gun.

Below the bore`12xand in line with the center of the barrel, the receiver or frame is provided in its. underside with a longitudinal recess or chamber 22, extending from its rear end t0 a point near its front, (see Fig.

6,) and the top of this recess or chamber communicatesl with a similarly disposed thoughnarrower recess 23, which in turn, communicates with a Vlongitudinally disposed cylindrical bore 24, the front of which is reduced and pierces the front wall of the receiver or frame, as indicated at 25.

' The bores 24 and 25, are occupied by the firing-pin 26, the front of which is reduced, as at 27 so that the pin and bores correspond in` shape and proportions'. The rear end of the firing-pin is reduced, as at 28, and terminates in opposite trunnions 62, forming whatmight be termed a T-head. In ad- 'fvance of thisy headthere'is mounted loosely uponthe rear reduced portion of theiiring- Vpin acollar 29,' between which and the enlarged portion 26 of the pin there is mount- 'Yed a'compressible coiled main-spring 30.

Pivotallysupported upon a transverse pin 32, mounted in parts hereinafter described, kis a sear 33, the same beinglocated in the narrow recess A23. This sear is provided at Vits rear upper corner with an angular locking-shoulder 34, which normally engages with ak corresponding notch or recess 31, formed in the underside of the firing-pin 26, such engagement being maintained at all times except when the gun is tired by means ofthe spring 30 upon the firing-pin. The

'lower-:rear corner of the sear isprovided with an extension 35, the upper edge of which is preferably inclined, and in advance of said eXtensionthe lower edge ofthe Sear is provided with a recess forming a shoulder `36, the functions of the extension'and' shoulder being hereinafter described.

y Closing the bottom ofthe recess or chamber in the receiver or frame isa cover-plate 37, (see Fig; 4,).the front end of the plate being, in this instance, reduced to form a tenon'A 3 3,v seatedV in -a corresponding Arecess 39, formed in the underside of the receiver and in advance of the chamber 22 therein.

To secure the front end ofthe plate in position, the tenen is apertured for a screw 40, which extends through Athe tenon and into the bottom ofthe aforesaid recess in the receiver.- Thisscrew may also be utilized for 'retaining the front'perforated end ofthe usual trigger-guard 41, the rear end of the guard removably enga-gingxa suitable kerf 41a, formed in the underside of the coverplate 37 The rear end of the cover-plate maybe extended a desired distance beyond the recess 7 of the stock and secured to the latter by a screw 42. Y 1

' The cover-plate 37 is formed with a central longitudinally disposed narrow slot 43, which extends nearly the length of the plate, and in the front end of this slot is pivoted, by means of a transverse pin 44, the cockingplate 45, the same having its outer edge shaped to approximate the surface of the grip of the stock. -A light spring 46,v in this instance flat, normally forces the cockingplate outward, so that,'as shown in Fig. 1, the outer edge ofthe cooking-plate normally extends somewhat beyond the cover-plate 37 in which itis mounted. Various ways may be 'devised for supporting the spring 46,l the manner shown merelybeing one of'such, and in this instance consisting of a short standard 47,` formed on the-inner side of the plate 37 and straddlingthe slot in'said plate and therefore the cooking-plate. This standard is provided near its upper end With'a small slot 48, transversely disposed'and of keyhole shape in cross-section. Into this slot .is

slipped. and retained the beaded end 49, of the spring. An vinverted stlrrup 50, may be vformed on the inner side of the bottom cover-plate 37 sorneV distance in rear-of' the standard 47, and within this stirrup the rear to be hereinafter described. When the cocking-plate is in its normal or projected position, as inFig. 1, a shoulder 64, formed at itsI upper forward end, engages the shoulderedjrecess 36 in the underside of the scar, therebypreventing a depression of the sear and therefore its disengagement with the firing-pin. 4

j The trigger 51, is pivoted upon the pin flat, and at one side is recessed, as at 51, (see Fig. 13,) to form apassage for the cockingplate. Above its point of pivot the trigger formed with a foi\v.-u' `lly disposed curved head 52, the end of which overhangs and rests upon the upper-.inclined edge or camsurface of the extension 35 of the sear, whereby, as will be evident, when the trigger pulled or retracted, the head thereof will serve to depress the rear free end of the sear and thus cause its shoulder Si todisengage from the `notch 31 of the firing-pin,'thereby libera-ting the pin and permitting it to be influenced by the linnn-spring 30 if the latter be compressed. This operation, however, cannot take place unless the cooking-lever has first been conipressed within 'the receiver so thatits shoulder 64 has disengaged from the shouldered recess of the sear.

As` shown by dotted lines (Figs. 1, :2 and the 'front wall of the receiver at each `side of the sear 33, may be provided with a loiigitudinal aperture 53, such `being in line fand communicating with shallow cavities formed in the `lower extension 55, of the barrel. ln cach of these apertures is a reciprocalflower locking-bolt 56, and the endsof these two bolts are connected within the recess 7 of the lgrip by means of a transverse bearing-pin 57. j j

Firoted to the inner side of the cookingplate and near its rear end, as at 58, is the rear end of a curved cocking-link 59, (see Fig. 12). This cocking-link travels over and is Aguided by the stirrup 50, the latter serving to .retain the link in position, and at its front end said link is reduced and apertured to receive the pin 57. As shown the link is rounded at itsforward end and in its movements travels against the inclined hardened guide-surface 63 of the upper cover-plate 10. i rocking-bar GO, "(see Fig. 11,) has its rear end bifurcatedQas at a. such bifurcations embracing the .reduced forward end of the cooking-link vand being apertured to lreceive the pivot-pin 5T before mentitnied. This cooking-bar (30 has its front end upwardly disposed and rounded. as at 62a. said endbeing adapted to ride against the guidesurface 65 of the upper cover-plate l0. ln rear ofitsfront end the cooking-bar is preferably slotted,` as at 61. and through such f slot projects the. T-head of the firing-pin. the "trunnionsflj of the head engaging the opposite edges of the slot 1n the cocking-bar.

30 is under very little tension, (entirely insufficient to project the firing-pim) and that therefore, the gun is in an absolut-ely safe condition, and though loaded, cannot possibly be accidentallyY discharged; and furthermore that such safe condition of the gun does not depend upon any safety device that might become broken and therefore inetlicient for the purpose Vfor which it is intended. ln other words, the lock-mechanism is inactive and incapable of discharging a shell because of the inactivity of the mainspring.

To bring the parts to the position illustrat-ed in Fig. Q, wherein the gun is in oondition to be discharged, it is only necessary to assume the usual position for firing, that is 'to clase the stock 6 of the gun with the hand. This clasping of thc stock necessarily raises or pushes inward the rear free end of the clicking-lever i5, thus withdrawing its shoulder 6i from its engaging position with the shouldered recess 36 in the underside of the sear 33, liberating the sear and rendering it Subj ect to a subsequentdepression b vineans of the trigger. The cookinglever, it will be seen, thus performs an additional safety for the gun, inasmuch `as even though theA main-spring should be, when retracted or expanded, slightly under tension, yet it will be incapable of projecting the iiring-pin because of the latter being locked by the Sear and the Sear in turn locked b v the cooking-lever.

As the cooking-lever is thus operated, the cooking-link moves forward, the upper rounded end of the link being guided by and traveling ,along the inclined guide-surface SZ-3 ofthe top cover-plate 10. This move- .ment of the cooking-link causes a similar forward movement of the cooking-bar 60, the upper rounded end of which travels forward alongthe lguide-surface 65 of said top cover-plate 10. During the latter movement of the cocking-bar, the firing-bolt being held stationary, therounded end of the cookingbar bearing against the movable collar 29, will force the latter forward against the tension of the main-spring 30, thus coinpressing said main-spring upon and inrear of the firing-pin Q6, The movements of the parts as described may, if desired, also simultaneously cause the lower locking-bolts 56 to move forward and engage with `the cavities ,if-t inthe extension 55 located at the underside of the barrel. whereby as will be evident. the barrel will be locked at three different points immediately before the discharge of the gun and during all times that the gun is in condition to be discharged.

It now only .remains to pull the trigger in order `to dischargey the gun, and such operation causes *the vupper curved head 52 Iofthe trigger operating upon the .upper inclined edge of the extension 35 of the sear, to depress the sear and thus disengage its .shoulder 34 from the notch 3l of the firingpin 26. Immediately the parts assume the position in which they are illustrated in Fig. 8, and as soon as the cooking-lever is released from the pressure of the hand, the

return-spring i6 will'return theV parts tofthe .original position shown in Fig. l. In the latter position the lower locking-bolts will have been withdrawnv from engagement with the lower extension 55 of the barrel, and to open the latter for the purpose of ejecting or withdrawing the empty shell it is only necdurable andvnot likely to become-impaired access.

or broken; and furthermore, that theV re- 'celver or frame is formed of a solid casting `rthe strength of which remains unimpaired byy excessive chambering or recessing. AIt

`will also be seen that the topV and sides of the chamber are closed and devoid of openings throughwhich moisture could obtain Be removing the top cover-plate access to the interior,v of the lock-mechanism is readilyobtained, and by removing the two screws .11 and 42the stock may bev removed and the whole internal mechanism exposed to View forfrepair, cleaning, or replacement of vany parts that might ,'be broken.
