To rLZZi whom, it may concern.-

Be it known that i', GEORGE E. VVITHERELL, e citizen oi' the United States, and a resident of Hartford, in the county of Hartford end- State of Connecticut, have invented certain new and useful improvements in Firing Mechanism for Firearms, of which the i'oiiowing is a epeciication.'

My invention relates to thet classici iire-l arms in which a plural number of hammers and Secre are employed and in which apnra number ofi hammers may be released by the operation oi a single trigger; and 'the olojectof,

I l 5v shotgun with parte broken away to snow construction and with. 'the gun broken down. Fig.. 2 is a side view of the seme with parte broken away to show construction.. 3 is e detei'l top plan view showing the reietive position oi' 'the sears., couplers, and intercepterslide citer the discharge of the'right-hand berrei end with the herinner oi the iei't-hand barrei cocked showing the position of these parte et time instent of discharge of the right-'hand 'barret Figa 5 is a detaii eide view of the sears, coupien intercepter-slide, and eport-ion oi a hain- Iner end illustrating e normal positionoi the perte citer the release ci the hemmerrom the Sear. ilig. 5 is a deteii view showing the preferred form of means for maintaining 'the Sear in the seme vertical position whether the hernrner be up or down. 4

While my invention is' appiicabie to eny form of iirearrn in which a piurei number of scars ie employed and -whether operated. by a single trigger or a 'pinrai number of triggers., l have chosen e douoie-barrei shotgun with .a plural. number ot triggers as the preferred Fig 4 is a like View9 but form of gun in connection with which to illustrate my invention; buil do not wish to be understood es .limiting rnyseif and do not iinit myeeif .to the invention disclosed herein soieiy in' connection g 'with e gun of the form herein shown.. l(

iin the accompanying drawings the numerai l denotes the stock` 2 the 'berre 3 the 'fore end'7 and fi the frame, of the gun, to which 'the lbarrel is pivoted the ordinary mennenI The gun also provided with cooking-levers 5 and hammers 6, Ail of the parte aicove mentioned may be of any weil-known end ordinary form, as they form no part of t'ne presentv invention except es to detailed con- Strnction of the hammer. The gun isralso provided with tnecnstoinerv parte nenni in devices of this'character, as the operating- Springs, reieeee-lever9 safety appliances, nc.

The hammer e is pivotaliy mounted in the freine inthe nenni manner and is provided on ,its onder Surface with ,a notch 'i' for engagement with the end of the sfeer 9.4 The hammer ie aise provided with neem projection 8 'that operetee in connection with thev Sear es wiii be v hereiniter described.

i The scar@ is-goivotaiiy mounted in the frame with its forward end projecting in position to engage the notch in the hammer. The teii i@ formed therein a recess li, niadevoy overturning the end of the scar-taii.

i conpier is pivotaiiy mounted on the een', prefereloiy near its front end, and nes et its iront ciad aconpier-carn 13 formed, preferebiy, on an `upward-proiecting peri; from the conoiera this conipier-cenrr coopereting with the cern proiec'tion 8 from the liernmer to ceuse the ccii'pier to iceewnrg on its pivot on the yseein The conoier has et its rear end e interni projection or nose which lies and has a icterai movement within the recess ll oi the scar-teil.. .lijsten-pin i5 is also iocated onthe coupler and by engagement with the overturned port of tiieeear-tail limits tile inwardswinging movement of the orward end. of the coupler.. of the Sear with its end pressing against the A. spring l@ is secured Vto 'the eide coupler at e point preferably adjacent to the point of pivotal. connection of the .coupler with the sesr.

The parts shove described es to cooking-lever1 hernnier Sear., end ports borne thereon have been described with reference to e single barrel of the gun, end it is understood that these parte are duplicsted in the gunthet is, s like set of perte used eppurtenent to each barrel-except that the arrangement of the perte is eltered to such extent only este make it applicable to the bcrrel in connection with which it is used, and like reference cherscters ere used in the drawings herein to denote the @erts sppurtensnt to loot-h the right end the left hand borrelsr A. forward trigger 17 is pivotslly mounted in the trigger-plete 19 appartenant te the liring mechanism of the rightfhend barrel.; end s rearward trigger 18 is also pivotallfmounted in seid trigger-plete end eppnrtenent to. the bring rnecnenisrn of the lei`thsnd barrel.'

Esch of these triggers is sdspted to engage the under surface of the sesr eppur-tenant thereto end to reise seid secr 'when the trigger is pulled backward.

lThe nies-,ns for preventing the accidentel discharge oli' the guincludes en intercepterslide 20., mounted in s slidevfey 2L the preferred form of the device end illustrsted herein these slider/sys ere formed in the seiety supporting-stu l 29d, the intercepterslide streddling said stud and having side pieces 23 located the slideweys on oppo site sides of the safety supporting sindn These side pieces lieve et their forward end guides 24.-, that project into grooves 25 in opposits sides of the projection 526 `troni the triggerplc.te. rlhe roer end E27 of the intercepter-slide is enlarged to considere-ble ex tent for the purpose of providing?. sufficient Weight to censethe slide to move against the force or' the intercepter-spring This inu tercepters-spring is located on e guide-goin 299 projecting forwsrd from the guide-pin snp port 50, secured t the triggenplste. This guidepin projects into the interceptenslide end serves as e, 'means of guiding thc letter when the guides 24; ere located outside of ne grooves Ain intercepter 3l is located on the end oi s projection from the forward endet the interceptenslide. iis shown in the drewings, this intercepter located between the scar-teils 1Q and in position to be interposed 1oet-ween vthe noses le on the couplers when the intercepter slide is located et the rearward. limit 'of its ploy.

. ne usuel safety appliances consisting the safety-slide 3% roclier 33, and tlmrnhslide 34. are erngloyed; but more detailed den scripties of this is deemed unnecessary herein.

lt is to be noted that peculiar feature of the coupling device herein resides in the lect that the coupler on esch of the sears is ofI geged with the opposite Sear onlj,r when the herinner eppurtenent to e given coupler is down sind the hammer snpurtcnent to the op posits coupler is raised or coclfiedu-thet is, with both of the hammers in normal position.z raised or lowered, each coupler is dis enge-.ged from, the opposite scar and each sesr is tree to act independently of the opposite scar.' lt will be obvious that when both herrels lieve been fired the couplers may assume any position, es they will be ceused to assume properposition es the hammers src thrown beck end the gun cocked. The noses oi the conplersnre suitably beveled, es shown, to allow the intercepter to be freely interposed between the noses and also to allow the nose of each coupler to engage in the recess oli" the opposite sesr with either of the sears in any position. By this construction l. :un also sbled to ineke the couplers practically' connterpsrts each of the other, except.A oi' coni-se, one must be arranged for s. right ind the other for slet-'t hond sesr. The couplers ere of the seme length, and the noses oi the couplers ere located opposite each oth r. This sirnplilies the construction both of the couplers and of the sesrs. l

The opere-tion of the device is es' follows:

l-oth hammers beine down, the bsrrcl is re ""LJ leesed by ineens of the top lever and the gun broken down., as shown in Figs. l and E2 of the dre-wings. ln this operation the hair; mers ere thrown backward by means of the coclring-levcrs 5 end the seni-s 9l each with t es the hammers ere thrown backward the cem projections 8 comiifig` in contact with the coupler-ceros 13 swing the resi' ends of the couplers outward,.so thntthe recess l1 in esch the is free to receive the nose oi' the coupler from the opposite secr. The norlnel vvposition, oi the intercepter-slide during this t vi u als operation `and9 in feet, s times except et the instant immediately following the disclrnrge ci the is at the forward .llnit of play, shown in L 2 3, and 5 oi the dren/ings. in this position the inten cept-er 3l is ,loc ted immediately in front ci the noses lll. oi the couplers. rlhe right-bend .rigger bein@ new pulled5 tl'le seer eyriurte nent to the mghtliend berrel is raised, reeing it from thenotch 7 on the hammer end allowing the letter to he thrown forward iinder the force of its spring. c This operstion discharges the rignt hond lisrreh end the force of the discharge censos the gun in its recoil to he forced sgeinst the shoulder of the user. From the naturel tendency c the user to resist this recoil and the spring action of the shoulder the gun is immediately thrown for-word in what is known the "counterrecoil.5 This counter-recoil causes the gun to move independent of the intercepter-slides#- thst iss the letter being of considerable weight to move in its slideways 'does not ie notches 7 on each of the hammers.

IIO

' the latter is therefore forced `forward independent lof' the intercepter-slide. rl`his causes the intercepter 3l to be interposed between the v noses of the couplers, so that neither is moved under the influencentE the coupler-springs 16. Immediately after the counter-recoilthe intercepter-slideQO is forced forward to its normal position by means of the intercepter springs 28 freeing the intercepter fromits position between the couplers and allowing the `coupler oi' the right-hand barrel to swi into the recess in the sear appurtenant to the left hand barrel. it will be noted that a pull of either the right or left hand trigger will discharge the other barrel of the gun.

The above description will apply equally well te the operation of the gun by pulling the free or left-hand trigger and discharging' the lelthand barrel lirst, it being necessary to substitute in said description 'the terms left for right and Lright for left wherever used.

A fault has heen'foundin'devices of this class prior to my invention from the fact that when a barrel is discharged the coupler immediately acts to unite the two sears. This .be-

y v ing accomplished before the counter-recoil acts and before pressure of the finger on the trigger has been released,the counter-recoil forces the gun auf trigger against the linger vand immediately discharges the opposite bar-l rel. 'By the use of theintercepter herein dez scribed it will be noted that this coupling operation cannot take place until after the counterrecoil, and therefore all danger of imme-a diately discharging the opposite barrel is overcome.

`-lt is to be noted that by the peculiar are rangement and construction ci' the intercepter-slide and the intercepter the gun may be held in any position wthout-adecting' the operation of the intercepterto perform its func tion. i I A. Sear-stop 35 (see Fig 2) is located underneath the rearendof the scar and serves to hold the sear in such position that the coup- Iers will surely engage the recess in the oppo' site sear Whether the l animer is up or down.,

except when raised in the movement of a trig-1 ger to discharge the gun. There 1s a stop ap purtenant to each scar. The sears are thus always maintained in the same verticalposiv tion, so that the coupler on one scar may readily cngage the opposite Sear. in the preferred form of means for preserving this vertical po sition oi' the scar, as shown in Fig. 65 the ham mer is so constructed that the portion oi' the scar in engagement with the hammer shall be always maintained at the same distance from the center of the pivot on which the hammer swings-that is., the point 35 on the hammer at which the scar touches when the hammer is down is the same distance from the center 38 of the pivot of the hammer as the point 37 adjacent to the notch 7 With which. the scar en1 gages when the hammer is up or cocked.
