Specification of Letters Patent.

FIREARM.

Patented July 29, 1913.

To all whom it may concern:

Be it known that I, HENRY B. FEBIGER, a citizen of the United States, residing at New Orleans, parish of Orleans, State of Louisiana, have invented a new and useful Firearm, of which the following is a specification.

My invention consists of an automatic magazine fire-arm especially designed for center-fire ammunition.

It further consists of improved means for detachably connecting the barrel and stockportions of such a fire-arm.

It further consists of improved means for supporting and guiding the breech-block of such fire-arm.

It further consists of a receiver for such fire-arm which will be completely closed to prevent leakage of gases and fumes from the exploding cartridges.

It further consists of improved firing mechanism for such a fire-arm.

It further consists of improved means for holding the breech-block in its rearward position.

It further consists of an improved safetycatch.

It further consists of improved ejector mechanism.

It further consists of other novel features of construction, all as will be hereinafter fully set forth. a The annexed drawings and the following description set forth in detail one mechanical form embodying the invention, such detail construction being but one of various mechanical forms in which the principle of the invention may be used.

In said annexed drawings :'Figure 1 represents a longitudinal section of the receiver, a portion of the stock-and a portion of the barrel of a fire-arm embodying my invention. Fig. 2 represents a side view of a portion of the barrel and a section of the fore-end. Fig. 3 represents a view of the outer end of the fore-end and of a portion of the barrel. Fig. 4: represents a transverse section of the barrel and an end-view of the fore-end. Fig. 5 represents a top View, partly in section, of the breech-block. Fig. 6 represents a sectional detail view of the receiver and the breech-block. Fig. 7 represents a section on the line ma: in Fig. 1. Fig. 8 represents a section on the line y-y in Fig. 1. Fig. 9 represents a topplan view of the cap, showing a part broken away and removed. Fig. 10 represents a side view of the cap with parts broken away represents a detail view of the firing mechanism.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, the reference numeral 1 indicates a portion of the stock of the fire-arm. A stock-frame, 2, is secured to the forward end of the stock by a screwthreaded rod, 3, and comprises a triggerguard, 4, a magazine-guide, 5, and a pair of parallel longitudinal guide-flanges, 6, extending from the magazine-guide to the closed rear end of the frame. A cap, 7, having a top, 8, and side-flanges, 9, straddles the frame and closes the sides of the same, being secured by screws 10. The barrel, 11, has its rear end screwed into and through a barrelframe, 12, to have the end, 13, in which the chamber is formed project rearwardvinto the frame and cap. The fore-end, 14, is secured beneath the barrel and to the barrel-frame by a screw, 15. An assembling-screw, 16, having a head, 17, turns freely in a hole, 18, in the barrel-frame, and has a tapering portion, 19, and a threaded end, 20, screwed into a threaded opening, 21, in the frontface of the stock-frame. The forward ends of the sides of the cap have undercut ways, 22, in which the rabbeted side-edges, 23, of a locking-plate, 24, slide, and said plate has an opening, 25, through which the chamberend of the barrel and the forward end of the action-slide extend, and the upper edge of which engages a notch, 26, in the upper side of the chamber-end of the barrel. The locking-plate has a tapering opening, 27, into which the tapering portion of the assembling screw passes. The side-edges of the locking-plate, near the lower end of the same, are formed with toothed or roughened bulges, 28, for convenience of sliding the late. p In assembling the gun, the barrel-frame carrying the barrel and fore-end is placed against the locking-plate, which is located within the undercut ways of the cap for the stock-frame, whereupon said plate is drawnend and the assembling-screw inserted and I screwed home. The tapering portion of said screw and the tapering opening in the locking-plate will cause the latter to be drawn down to tightly engage the notch, and will tightly draw and hold the parts together.

An action-slide has a body-portion, 29, slidable upon the upper edges of the guideflanges of the frame, and flanges, 30, straddling said frame-flanges. Said body-portion forms the breech-block, and said slide flanges extend forward from the breechblockto form action-bars, 31, connected at their forward ends by a cross-piece, 32, having a screw-threaded socket into which the rear end of an action-rod, 33, is secured. The action-bar and action-rod are longitudinally slidable within the fore-end, and said rod is guided in guide-blocks, 34, .secured to the under side of the barrel. coiled spring, 35, is coiled around the rod and bears against the rear guide-block and a stop-pin, 36, in the rod, serving to pull the action-rod and slide forward. The forward end of the rod extends beyond the-forward end of the fore-end and is hollow, and a pin, 37, is confined within such hollow end and may be rotated a one-quarter revolution in the same. A knurled button, 38, is formed upon the end. of said pin and has a portion of its periphery cut away, at 39, to admit of it sliding beneath the barrel while, when forced rearward and partly turned, its uncut periphery can engage a notch, 40, in the under side of the barrel and hold the actionslide, bars and rod in their rearmost posi tion.

Thebreech-block has" an axial bore, 41,

.having a contracted forward end and a longitudinal slot, 42. in its under-side. A

firing-pin, 43, is slidable within said borev and has aspring, 44, forcing it forward. A web, 45, extends laterally from said pin and is slidable in said slot, and said web is formed with a f orwardly-facing sear-shoulder, 46. 1

A sear, 47, is pivoted at its forward end between the guide-flanges, of the stockframe, and has a sear-shoulder, 48, upon its upper edge, adapted to engage theshoulder of the firing-pin.

A trigger, 49, is pivoted between the guide-flanges to project within the triggerguard, and has a rearwardly extending arm, 50, to which a post, 51, is pivotally connected. The upper end of the said post is guided in an adjustable socket, 52, between the guide-flanges, and a spring, 53, is coiled around said post and bears against said socket and the arm of the trigger to throw the latter forward. The trigger has an upwardly projecting arm, 54, to the upper end pivotallyconnected'and the forward end of which bar is movably connected to a downwardly extending arm, 56 of the sear. A

spring, 57, is interposed betweenthe rear end of the sear and the trigger-bar to force the sear nvalid.

A spring-actuated extractor, 58, is secured in a groove in the forward end of the ln-eech-block to project into the chamber and extract the exploded shell in the usual man ner. On the side opposite to that of the extractor, the breech-block is formed with a groove, 59, within which slides an ejector formed by a bar,- 60, having a nose, 61, at its forward end and having a laterally projecting plunger, 62, which slides in the bore' of the breech-block, projecting through a slot, 63, in the same, and having the rear end. of the firing-pin spring bearing against it. A pin, 64, serves as a stop for the rearward movement of said plunger. The right-hand side of the cap is formed with an ejection opening, 65, through which the exploded shells are ejected.

A safety catch is provided within the trigger guard and consists of a bar, 66, sliding over a slot, 67, in the bottom of the receiver and having a finger-piece, 68, sliding in the slot. The upper face of the bar is formed with two notches, 69, into which the end of a spring, 70, may engage. The forward edge of the trigger is formed with a, nose or shoulder, 71, beneath which the rear end of the bar may engage whenmovedrearward, and this will prevent the trigger from being pulled. The forward end of the trigger-bar is oblique, as at '72, and may, when the trigger is pulled and the bar moved forward, ride 'upward upon a pin, 73, between the guide-flanges, and the trigger-bar has a notch, 74, engaging a pin, 75, in the lower arm of the sear.

When a charged .magazine has been inserted into the magazine guide and it is desired to fire the gun, the action rod is pushed rearward and again allowed to come forward. As the breech-block moves rearward, the shoulder of the firing pin passes over the shoulder of the sear, and when the block again moves forward, the searshoulders engage and the firing pin is held and compresses its spring while the breechblock moves forward. The forwardly moving breech-block carries the uppermost cartridge from the magazine into the chamber of the barrel, and the cartridge may now be fired by pulling the trigger which pushesthe trigger-bar forward and rocks the sear to disengage its shoulder from the shoulder of the firing pin, allowing the spring. of the latter to drive it forward to strike the fulminating' cap of the cartridge. The recoil from the explosion in the cartridge will throw the breech-block rearward, when the extractor will withdraw the empty shell and the rear end of the ejector will strike the rear end of the receiver to cause the ejector to tilt the shell and eject it, as appears in Fig. 6 of the drawings. As the breech-block is again moved forward by the action-spring, the succeeding cartridge is fed into the chamber and the firing-pin rod to bring its periphery into the notch in the under side of the barrel. 7

When firing a gun, the natural tendency of the gunner is to retain his pull upon the trigger for some space of time. If the pivot-connection between the trigger-bar and the sear were in continual engagement, the sear would be retained pulled down, and the recoiled breech-block and its sear-shoulder would pass rearward and be drawn forward without getting into engagement with the shoulder of the sear and, consequently, without setting or cocking the firing-pin as the breech-block moves forward. As, however, the pulled trigger pushes the trigger-bar forward and rocks the sear, its inclined forward end rides upward on the stationary pin 73, until the notch in the bar is disengaged from the pin in the lower sear-arm, when the spring between the sear and trigger-bar rocks the sear upward to admit of the sear-shoulders engaging as the breechbolt moves forward, thus retaining the firing pin and compressing its spring. When the trigger is now released, the trig er-bar is drawn rearward and itsnotch wllI again engage the pin ofthe sear-arm.

As the receiver-consists of only two parts, the frame and the "cap which completely incloses the sides 'of the latter, a very strong structure is obtained-and tight joints can be obtained, preventing leakage of gases and powder-particles.

The gun may be easily assembled and taken apart, and there are no loose parts which can be lost when it is taken apart. All moving parts of the firing, ejecting and extracting mechanism are inclosed within the frame and cap, and are completely protected against dust and moisture in the atmosphere.

Other modes of applying'the principle of my invention may be employed for the -mode herein explained. Change may therefore be made as regards the mechanismthus disclosed, provided the principles of construction set forth, res ectively, in the following claims are emp oyed.
