8.5.1 m. 499,400. on man embracing straps 5, and the same are secured v tothe stock o'rbutt' 8 in theusual manner. 1 The barrel 9 hasits reare'andproVided-a'vith a conical or reduced portion 10, the same be.-

the concaved seat 3 with which the receiver is provided." This conical portionlo also has formed upon it a tenon 11' which projects' fromits upper side, and the sameengages with a hook or mortise 12- formedonythe front end-at ,the upp'er side of the'receiver. "The underside of the barrel is provided with-ade-' pending lug 13,-the back edge ofwhich has a notch 14 formed therein.

the barrel isthe tubular m same being near its front end. The rear end'QflthemagaE zine is externally threaded into'thethreaded I I socket 4. The outer end of the .rnagazine is concaved and provided with'a perforation-l6, and the upper side of the magazine is pro- .vided with an opening or slot 17, into which the lug 13, which by reason ofthe notch 14 is L-shaped, passes. A locking-pin lsis mounted loosely in the perforation 16 at the front end of the magazine, a-nd'isfprovided at its inner end with a flanged locking-head or disk 19. In advance follower 29 is arranged in-the magazine, and

a coiled magazine spring 2 1 is interposedbe andzthelocking head or .tw'ee'n the follower disk '19, the tendency of the spring being .to

Arranged below v agazine 1-5, the bored from its'rear end to a point.

of the locking-pin a ing adapted to fit snuglyyet-removably into I throw" the pin to'the front-andhence cause the flanged locking-head to engagewith the notch 14 of the L-shaped lug 13. By such an arrangenient' it .will be seen' -that'to'remove the barrel for any purpose, as for cleaning, repair, or for the substitution of another bar:

rel, it is simply necessary to press the pin 18 to the rear so as to diseh gage its flanged locking-head or disk with the notch 14 of the L- shaped lug 13, and afterward elevate the front end of the barrel so as to disengage thetenon with the mortise 12 of the receiver. To replace the barrel the operation is simply re versed; the tenon is first engaged with the mortise, the barrel being disposed at an angle to the receiver during such engagement, after which by lowering the front end of the barrel into parallelism with the receiver and upon the same, the lug 1 3 will pass into the opening 17 of the magazine, and the locking-disk engage with the said lug.

Extending transversely through the receiver is the shaft or pin 22, and located rotatably thereupon is the hub 23, upon which are located the unions-24, the same being spaced a short distance apart. A transverse pin 25 passes eccentrically through the two pinions and extends slightly beycndjtheir outer faces, and each of said pinionshas its inner side segmentally cut away or recessed as at 26.

Secured to the under side of the receiveris the trigger-guard27, and the sarneis arranged under the usual trigger-opening of the receiver, and in advance of said opening is provided with a spring-detent 26, whose upper conical end extends into the receiver. Pivoted at 29 within the trigger-opening of the receiver is the trigger 30, and the sameis provided in rear of its pivot with the projections 31 and 32 and with the notch 33 in rear of said projections. In rear of the triggerguard the receiver is provided with an open ing or slot in its under side, and arranged therein is the finger-plate 3 1 of the safety-lever. This fingerplate has formed on its front end a beveled finger 35, and in rear of the same there extends upward and forward from said plate a pair of bell-crank levers 36 which are parallel to each other and have their front ends or extremities perforated and pivoted by apin 37 within the receiver. At their angles these levers 36 are provided at their inner sides with inwardly disposed beveled locking-lugs 3S spaced a short distance apart. A spring 39 is arranged in the rear end of the receiver and bears at its free end upon the finger-plate of the safety-lever so as to normally-depress said rear end and the finger 35 into the notch 33 at the rear end of the trigger and abut against said trigger preventing the latter from being pulled until the finger-plate of the safety-lever has been pressed upward by'the pressure of the fingers upon the stock.

For the purpose of preventing children and other irresponsible persons from accidentally pressing the safety-lever upward and for obviating any accident while transporting the gun or handling the same carelessly, I prefer to employ a sliding catch 40, locating the same in a slot or recess 41 in the rear end of the receiver and adapting it to be moved forthe rest for the cartridge.

ward so as to engage its catch pin 42 above the rear end of the plate 34. \Vhen this is done the finger-plate cannot be elevated so as to unlock the piece, nor is itlikely to be accidentally moved by any handling which the arm may receive.

Located in the recesses 26 of the pinions 24 is the front end of a sear 43, which as shown, is pivoted by a transverse pin 44 in rear and above the axes of the pinions, provided at its front end upon its upper side with a beveled shoulder 45 and in rearof the pivot with the tail or extension 46. The usual sear-spring .47 is engaged under the sear-catch and serves to normally depress the rear or tail portion of the scar and elevate the front end. The rear end of the sear rests upon the projection 32 ,of the trigger, and hence any elevation of the trigger, as thus engaged with the rear end of the'sear, will cause an elevation of the rear end of the searv 51, which engage loosely with the transverse pin 44 at 48, and in rearof the same with an extension or finger 52, whose extremity is beveled and which rests against the projection 31 of the trigger. In frontof the lugs 51 the armof the carrier is curved upward and is provided with a hook or catch 53. Be youd this point the arm is provided with a stop-shoulder 54,,and bryond this is provided with the curved carrier-plate 55 which forms The arm of the carrier, it'will beunderstood, passes between the two pinions, and the hook 53 of the arm lies in the path of that portion of the trans verse-pin 25 that passes through the pinions, that is between said pinions and books, so that when the pinions revolve the hook of the carrier-arm is engaged by this pin 25 and the arm elevated so as to raise cartridges from the magazine to the breech of the barrel.

The opposite walls of thereceiver are, near their upper edges, provided with the horizontal guide-ribs 56, and the same form the ways upon which movesthe breech-bolt 57. This breech-bolt 57 has its under side provided with a central slot 58, which extends nearly from end to end of the bolt, and at opposite sides of said slot is provided with teeth 59, thus forming ara'ck-bar. At its front end the bolt is provided with ordinary extractors, adapted to engage the flange ofthe shell; and said bolt isfurthermore provided with alonwhich is slightly reduced at its forward half.

This bore communicates with the slot 58, and

The sear is I arranged within the slot is the beveledshoulder 45 of the sear, the same being yieldingly pressed upward into the bore. The rear end of the bore of the breech-bolt is provided with a threaded plug 61, the same having a perforation concentric with that of the bore. Arranged within the bore is the firing-pin 62, the same extending throughoutthe bore and adapted to pass rearward through the perforation in the threaded plug 61. The firingpin is provided at an intermediate point with an annular shoulder 63, and in rear of the same there is. located a coiled springtii, the rear end of which bears against the threaded plug. The office of this threaded plug is to permit of the introduction into the bore of the firing-pin and the coiled spring, and retain the latter in position. The tendency of the spring, of course is to throw the firingpin to the front, its travel being arrested by the abutting of the stop 63 againstthe annular wall formed within thebore by the contraction of the front pdrtion thereof.

It will be obvious that by a forward movement of the breech'bolt the annular shoulder 63 will engage with the beveled shoulder of the sear and a continued movement of the breech-bolt may take place while the firingpin will remain stationary untilliberated by p a withdrawal of the sear through the medium of the trigger and a consequent throwing of the firing-pin against the cartridge.

It will be observed that each of the rackbars 59 is in engagement with a pinion '24, and that as shown each of said rack-bars .is provided near its rear end upon its outer side with a plain or untoothed portion 65.

In line with the 'pinions and above the; breech-bolt the roof or upper side of the receiver is provided with a chamber 66, and pivoted within the chamber by a pin 67 isa lockin g-lever 68, which extends forwardly and is adapted to dropint-o the path of a shoulder 69 formed on the upper side of the breechbolt by a reduction of the latter. I ing-lever is of bell-crank shape, that is to say it is provided with a pair of depending, in the present instance compoundly'curved, arms or branches 70 whose lower extremities embrace the outer sides of the pinions and at their inner edges are provided with terminal hooks 71 that lie in the paths of the ends of the transverse trip pin 25.

The upper side of the breech-bolt is recessed longitudinally, and arranged within the recess and pivoted intermcdiately by a transverse-pin 72 is a catch 73 whose front end terminates in a depending hook 74, and whose rear end forms a trip-finger 75 that extends beyond the shoulder 69 on the upper side of the breech-bolt and into the path of the free end of the locking-lever 68. When the locking-lever is raised the catch 73 is depressed by the spring 76 so that its front end takes This lock-- when inits rearniost position, to close the opening 2 at the side and bottom of the receiver. The rear end of the fore-arm has attached thereto in any suitable rigid manner a rackbar 78, whose t'eeth'are formed upon its upper side and which meshes with the teeth of the pinions 24 under which it passes. The rackbar' furthermore passes under the beveled lugs 38 of the bell-crank arms of the safetylever, and such passage is not impeded when the rack-bar moves to the rear. Any attempt, however, to move the rack-bar to the front is opposed by the lugs 38, in that the latterv engage with the rear tooth of the rack-bar and the latter cannot be moved until the safetylever is elevatedso as to remove the lugs from their engagements.

This'compl'etes the construction of my improved fiiearm, which it will be seen comprises but'few parts and they of simple construetion, easy of assemblage, and strong.

The operation will at once be obvious from the foregoing description, but in order to avoid any-mistake thereof I will briefly state .it as follows:

Presuming that the magazine is. filled with cartridges and that a cartridge is in the barreland the parts are in the position shown in Fig. 4,'the piece or arm is gripped in a manner that is usual, the fingers of the right-hand passing under the finger-plate of the lockinglever and hence elevating the same so as to liberate the trigger. The left hand grasps the fore-arm 77, and the piece being brought to the shoulder, the trigger is pressed. The pressure upon the trigger causes the rearor tail end of the sear to raise and withdraws the shoulder of. the sear from engagement with the stop or shoulder of the firing-pin, permitting the latter to be thrown by its spring against the cartridge, and by its impact exploding the same. Having fired the piece it is desirable to discharge the exploded shell and elevate a new cartridge to the barrel, which is accomplished as follows: The mechanism for accomplishing this is operated, or set in operation, by a forward movement upon the part of the fore-arm, and the recoil of the piece when discharged will cause the shoulder of the person firing the piece and against which the butt thereof rests, to swing backward slightly, which facilitates or aids an opening of the chamber lgy a rearward pull of the piece in contradis inction to the operation of the fore-arm by the left-hand of the operator, so that the operator does not have to move his left hand the entire distance necessary to open the piece, but, as will be obvious, as he moves the left hand forward the right hand moving with the shoulder that swings backward to the-recoil of the piece, draws the piece with it. This movement of the fore-arm of the piece and the left hand of the operator is insufficient to disconcert the aim of the person firing and may be accomplished in an instant.' The movement of the fore-arm causes the rack-bar 78, which enizo III

gages with the pinions, to rotate the same, and such rotation will necessarily cause the teeth of the pinions to operate in the teeth of the breech-bolt and thus retract the latter. Such retraction is permitted so far as the locking-lever 68 is concerned, in that theends of the pins 25 serve,-througn the medium of the bell-crank arms 70 of said locking-lever, to elevate the same, and it is to permit of this elevation previous to the retraction of the breech-bolt that the recesses in the rack-bars of the breechbolt are provided, whereby, as will be obvious, the pinions can then travel a short distance, namely, enough to elevate the locking-bolt before the teeth of the pinions operatein the teeth of the rackbars of the breech-bolt. instant that the locking-lever 68 is raised the catch 73 drops into the path of the firing-pin and prevents any accidental explosion, if, for instance, it should be desired to withdraw an undischarged cartridge. This forward movement of the fore-arm also causes the intermediate portion of the pin 25 to engage with the hook 53 of the arm of the carrier and causes said arm to rise together with the carrier, and thus deliver or hoist the cartridge to a point in rear of the breech of the barrel. The line of the cartridges within the magazine is arrested by abutting against the front end of the arm of the carrier, The cartridge is forced into the breech by the forward movement of the breech-bolt, as is usual. Immediately that the fore-arm is returned to its former or closed position a reverse operation or rotation .of the pin-ion takes place, and the carrier is forced to its lowermost position, Where a fresh cartridge is forced upon it from the magazine. The teeth of the pinions engaging with those of the breech-bolt serve to actuate thebreechbolt in a forward direction, and the latter pushes the cartridge snugly into the breech of the barrel, after which the pin 25 engaging with the hooks 71 of the arms of the locking-lever, draws the same down into position so as to lock the bolt against rebound by the explosion and elevates the locking catch 73 out of its operative location with reference to the firin'g pin, so that all that is neccessary to be done to redischarge thepiece is to repeat the operation first described.

As before stated, the rebound of the piece when discharged of course causes the shoulder of the person firing to swing backward, and thus as before explained, aids in the operating of the parts, so as to expel the exploded shell. The natural movement of the shoulder to regain'its former position, together with a short rearward movement of the left hand of ,the operator, serves to close the forearm over the opening in the receiver and accomplish the secondportion of the described operation, namely, the elevation of the fresh cartridge to the breech of the barrel and the forcing of the same into the barrel by the breech-bolt.

From the foregoing description in connection with the accompanying drawings, it will The be seen that I have provided a fire-arm that consists of very few parts, the same being durable, readily removed, and positive in their operations, and that by their movements I produce an arm that is rapid in its action and in whose handling the possibility of accidents is reduced toa minimum.

I have shown my invention as adapted for a rifle, but it will be obvious that it niay be.

applied with equal success to a shot-gun.
