FIREARM.

To all whom it may concern: Y

Be it known that I, Cnaanns A. Nansen, a citizen of the United States, residing at Utica. in the county of Onedia and State of New York. have invented certain new and useful Improvements in Firearms, of which the following is a specification.

The object of this invention 1s to provide a gun having many of the desirable featuresof the gun set forth in the Savage Patent X0. 839517 but possessing. in addition to im- I provements which increase the simplicity of construction. durability. stability, safety and general efficiency of a gun of that kind,

nism respectively associated with them; Fig.

4- shows the receiver-including part of the gun partly in right side elevation and partly in section; Fig. 5 shows said part of the gun partly in left side elevation and partly in section: Fig. 6 shows the forearm-including part of=the gun partly in side elevation and partly in section: Fig. 7 is a plan of portions of the receiver. action slide and the means for returning the action slide to its normal position; Fig. 8 is a plan of the rear part of the forearm: Fig. 9 is a sectional 'ie'w on. line :cw of Fig. 2, looking forward; Fig.

10 is a perspective view of the cartridge stop or abutment and breech-bolt: Fig. 11 shows the magazine platform blocking the advance of the breech-bolt after effecting ejection of the shell 0' the last cartridge in the magazine: and. ig. 12 is a detail of the ejector.

The receiver or frame. substantially similar to that in the patent to Savage abovementioned. comprises a stock section a and a barrel section a which lie face to face when assembled. being, interlocked by the mortise and tenon connections 7) and 0 (Figs.

"2, 3. and T) and held together by the single thumb-screw (I entered through the section 0." into section a.

f is the stock and g the barrel.

it is the magazine, of the box type, suitably held in the receiver bv the latch 2 substantially the same as in the said Savage patent.

The action-slide is a bar j guiaed in a straight slot iv in the inner face of receiversection a and projecting through the front wall thereof; its rear end. has a handle for ianually retracting the action slide, said handle consisting of a knob. Z and .a pivoted notched part or latch onof the action slide which carries the knob and moves in a slot a 1) in receiver-section a and has its hook me engageable with a notch m" (Fig. 3) at the rear end of said slot and onthe inside to hold back the action slide when depressed against a spring'o (Figs. 5 and 7 The forward end of said action-slide carries the lateral collar 7) traversed by the pin q. Directly under the barrel is a tubular spring-case 1' penetrating and guiding said collar and having longitudinal slots 8 in which pin Q plays, the rear end of said spring-case being received by the front wall of receiver-section a and the forward end supported by the stirrup 2* having a dove-tailed base u entered into a lateral similar shaped slot o out in the under side of the barrel. A spiral spring to, housed in the case, and interposed between the pin 57 and a suitable abutment at the rear end of the case. presses the action slide forward. The forearm 1 suitable hollowed out to fit the under side of the barrel and house the spring-case and stirrup t and afiord the necessary clearance to the action-slide latch 77b. is secured in place in a way calculated to produce a simple, stout and readily assembled construction. thus; It has its rear-- ward end formed as a broad tenon .2 fitting a mortise 2 formed in the front wall of the receiver. the vertical surfaces of said tenon and mortise being curved in plan (Figs. 7 and 8) screw 3 enters the forearm and receiver at said joint. while ascrew 4 is passed through the forearm. stirrupt and case 'r, icing tapped into thestirrup and having a reduced end -lwhich enters the barrel and so locks thestirrup against lateral movement (Fig. 6 in this way the forearm is secured to thebarrelaud receiver so that the construction is at once simple .and adapted to fmrilitatc assembling.lbesides. the joint between the forearm and receiver is llO v I quire .but a single screw (-3) topreserve it,

rlateral lugs 5 and 6;

and to prevent the wood of the forearm against splitting or chipping at the joint. The action slide has-itsreariendthe spaced The. breech-bolt 7 is generally like the breech-bolt described inthe said Savage gpatent, being guided. bythe side walls of the receiver, having. a cheek-piece or wall 8 on one, side rest1ngon the action-slide- (which, being thicker than'slot k is deep, projects therefrom) and abutted above by the top watll of the receiver; it has. a' firing pin 9, 'a-n' extractor 10 coactive, with. projections 10 ";to'h0ld the cartridge and, on'the side thereof"relativelyopposite to sai'd cheekpiece, a longitudinal slot 11 and is otherwise formed and operates t e same as in the said Savage patent (excepting (that it v lacks the means for blocking it against recoil), the slot 11 being adapted to receive the acting endof the .ejector 12 which springs inwardly to throw the extracted she'll out of the'ejection aperture 13 in the receiver when the receding breech-bolt, by

its extractor, clears the shell from the barrel.-'

Thefb'reech-bolt has a a downwardly pending tail 7'fitting between the: lugs 5 and 6on the action-slide. v

' The ejector 12 is a lever havingits fulcrum formed by a ook 12 (Fig. '12) engaging in an annular channel 12 formed in the inner side of the head 'o'f-a screw lit; the lever and screw head are received in a communicating slot-12 and countersink 13 and, a-sprin 15 in the slot presses the free or act- D en .offthev lever outwardly, tending to 1 hold it to the limit of outward movement thereof whichis'afl'orded by the contact of the inner end 12' of the lever against the bottom of the-countersink.

- The top wall of the receiver has a recess or'c'ha'mber 16' formed immediately back of the barrel-breech, the object'of which is to afford ample blow-back relief for the escaping products of combustion and gases on firing, which would otherwise. be unduly confined in'the relatively limited space. formed v.byftlie top and sides-of the receiver chamber, the underlying magazine and its contents,

the barre1 breech and front end of the breech-bolt and so interfere more or less wdththefree actionlof the parts and sooner or later foul the piece. For checking the 3 1G and being normallyv fresh cartridge rising from the magazine at aposition in line with and guiding it into thebarrel breech I employ thestop 17'shown inv Figs. 3;4, 5, 10 and 11 which is a slender elastic metallic strip; having-parallel upstanding cheeks 18 secured in a slot 19in the top wall of the receiver by a transverse pin 20 and a spo'onshaped free end 21, its said spoonrshaped end traversing chamber g lr level of the top of'the 'elow the.

" slilii botligthesearandsear tr p againstkzthe ing to'the upward pressure of the magazine spring it-will occupy such a position rela'- tively tothe bore as then to perform its function properly as a guide to the cartridge in breeching the same.

Iii-order to insure the breech-bolt (which is the :only freely removable element of the mechanism) remaining properly assembled with the receiver section a on taking down I provide the member 17 with a lug 22 which is received by the groove 22 at the top of the breech-bolt. v

The hammer 23, having the head 24 to impinge against the firing pin and the cam face 25 tO I 'QCBlVQ the \viping action of the lug 6 on the action-slide, in cocking the hammer, and the'spring-pressed thrust-bar 26 for 'the hammer are substantially the same as insaid Savage patent.

'The' trigger 27, in the form of a rear wardly' openhousing. is fulcrumed at its mid-upper portion on the pin 28, being pro- -tected by the usual guard 29 affording a backing for the magazine.- On the pin 28 is fulcrum'ed the sear 30 having the forwardly,

rearwardly and long downwardly projecting arms 30, 30 and 30". On a pin 31 in the trigger is fulcrumed the sear-trip 32 having the forwardly curved upperarm 32 and the downwardly projecting arm 32' and on-its upper arm the shoulder 32" to engage under the end .of arm- 30 of the sear.

wardly on the locking-bar 35, suitably guided in a slotin the'thrust-bar 26 and stepped on a cross-pin 36 in the rearwardly projecting arm of the trigger, through the thrust-bar forces the trigger forward, normally holding the upperedge of its front wall 27 in contact with the sear arm 30',

-which rests against thehammer; the locking-bar (movable upwardly under the influ- I ence of the trigger and also forw'ard 'and backward pivotally on the cross-pin 36) is received by a slot 37 in the receiver and is moved forward or backward to bring one of its stepped shoulders 35-, 35 under the shoulder 35" at the rear of said slot by the usual slide'38 which is penetrated by a stud 39-on the locking-bar. The action of these parts is 'as'follows: The parts beingoin the cocked position (Fig. 4) rearward movement of the trigger causes the'sear trip, whosefulcrumis in the trigger, to tr p sear (-fulcru-med on the stationary pin 28)f "so that the hammer falls; spring 33 meanwhile hammer and as'the hammer falls its cam 23" wipes the sear trip out of engagement at its shoulder 32? with the sear arm 30", while the sear arm 30 wipes over the concentric surface 23"" of the hammer. If (there being no charge in the gun) the hammer remains down, as in Fig. 9, the trigger will at this time be held from any lost motion, being retained against the sear arm 30, which itself abuts'the hammer, by the shoulder 35 of locking bar 35 engaging shoulder 35'. If, f recoil occurring from an exploded charge, the hammer is thrown back. the sear. being clear of the sear trip and hence of the trigger, is free to'act independently of the trigger to engage the hammer notch 23 and cock the hammer although (as will usually be the case; the operators finger has not allowed the full return of the trigger which. when it does move forward. brings the sear trip opposite the low part of cam 23 whereby it will be allowed to again assume dogging relation to the sear. In the cocked position of the parts the trigger may be locked by moving the slide 38 rearward so.

asto bring shoulder 35 on the locking bar under the shoulder 35".

The stud 39 is sufficiently longer than the slide is thick so that 'with the trigger forward (hammer cocked) its extremity is aproxiniately flush with the top of the slide:

with the trigger back (hammer down) the stud projects, indicating to the operators thumb the uncocked condition of the piece.

The magazine It has the usualplattorm l0 to elevate the cartridges contained therein and to block the breeching movement of the breech-bolt upon the magazine becoming empty (Fig. 11). the same as in the patent to Savage X0. 885868.

Operation: The operation will be apparent to those familiar with this class of guns. To breech the first cartridge in the magazine the action slide j is retractedand then allowed to return under pressure of spring 11:, forcing the cartridge (which has been meanwhile pressed by the. platform 40 into the grip of the devices 10 10 on the breech-bolfl into the breech. Upon the gun being nov fired the recoil of the breech-bolt. through rho action-slide, throws back the hammer which is immediately cocked, while the spent shell s extracted and ejected and, on the return of thr action-slide at l breechbolt to their normal positions, a fresh cartridge breeched. hen the last cartridge has been exploded the o1 e h-bolt and actionslide will be locked back by the platform 40 rising and blocking the return of the breechbolt as illustrated in Fig. 11 thus indicating that the piece is empty. To now recha the piece, the action-slide is locked back the latch m, the empty magazine withdrawn and a loaded one substltuted,

whereupon, the luiCll being released, the

breech-bolt will in advancing pick ml the uppermost cartridge and breech it in the usual way, ready for firing.

Having thus fully described my invention,

' what 'I claim as new and desire to secure/by placement, said means affording in one of the sections of the divided receiver support for one of the upper and lower sites ofthe breech-bolt and a yielding retaining member engaging the. breech-bolt at a relatively opposite side thereof and separably interlocking the same with said section. substantially as described. v i
