BREECH-LOADING GUN.

' Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed August 3, 1904. Serial No. 219,324.

To all whom it may concern.-

Be it known that I, HARRY D. BERNARD, a citizen of the United States of America, residing at Warren, in the county of Marshall and State of Minnesota, have invented certain new and useful Improvements in Breech-Loading Guns, of which the following is a specification.

This invention relates to firearms, and particularly to a breech-loading gun of the maga zine type.

An object of this invention is to provide a firearm of the character noted in which the breech-block and the operating mechanism except the action-rod is contained within the receiver and stock.

Furthermore, an object of this invention is to provide a firearm of the character noted which can be produced as a hammerless gun; and the invention comprises in part novel means for resetting the plunger and firing mechanism which may be released by a pull on the trigger.

Furthermore, an object of this invention is to provide novel means for removing the shell from the magazine and for delivering it to the barrel, the said mechanism being confined within the casing, so that no parts of the said mechanism project except the action-rod.

Furthermore, an object of this invention is to provide novel means for reciprocating the breechblock longitudinally and for oscillating the said breech-block vertically; and the invention further comprises novel means for retaining the breech-block closed and locked in order that the recoil incident to the firing of the gun may not displace or dislodge the breech-block.

The invention further comprises novel means for operating an ejector for causing the empty shell to be thrown to one side free from the breech mechanism.

Finally, an object of this invention is to produce a gun of the character noted comprising comparatively few parts which will rove efficient and satisfactory in use.

With the foregoing and other objects in I view the invention consists in the details of construction and in the arrangement and through the breech and through the gun stock. Fig. 2 is a similar view with the parts in a different position. Fig. 3 is a perspective view of the breech-block. Fig. 4 is a erspective view of the carrier and shelli ifter. Fig. 5 is a perspective view of the action-rod and the arm carried thereby. Figs. 6 and 7 are detail perspective views. Figs. 8 and 9 are fragmentary sectional views of the breech-block, showing the means carried by the plates thereon for gripping the flange of a shell. Fig. 10 is a detail sectional view taken on the line 10 10, Fig. 2. Fig. 11 is an additional detailed view in section.

In the drawings, A indicates the receiver, having one corner cut away, as at a, for the purpose of permitting the application and removal of the shells, and the inner side walls of the receiver are provided with inclined shoulders a, which form tracks or ways on which the breech-block B is slidable.

The receiver is provided with any suitable barrel 0 and a magazine 0 which may be of any desired construction, the said magazine of course having a spring-pressed follower d for normally pressing the shells or charges rearwardly.

In one side of the magazine is formed a longitudinal groove or recess 8, which extends the entire length thereof. In this groove rides the elongated lug w, formed on one side of the follower cl. By this means or arrangement the follower d is held against rotary movement, which would tend to affect the efficiency of the follower.

At the point where the magazine enters the receiver I pivot a latch d by the pivotal pin (1 the said latch having its nose extending above the lower wall of the magazine and serving to arrest the shells successively as they are forced from the magazine by the follower. The heel end d of the latch extends below the wall of the magazine and at the outward limit of movement of the actionrod the said heel end is forced upwardly, thus causing the latch to swing downwardly and release the shell. The latch may be tripped by a lug on the action-rod or by any other suitable means which will accomplish the result. The shell-carrier E occupies a position at the bottom of the receiver and is pivoted by the pin 6.

The carrier terminates at the rear in two curved fingers 6, each of which has an inwardly-extending stud e adapted to ride in a cam-slot (to be hereinafter described) in the breech-block. The carrier is provided with a longitudinal slot 6 in which the lifter F is pivoted on the pin f, the said lifter comprising two fingers connected at one end by a cross-piece f, which cross-piece is engaged and depressed by a fin (to be hereinafter described) of the breech-block. The breechblock B contains a firing-pin B, which may be held retracted in any suitable manner, and the firing-pin is moved into alinement with the plunger G when the breech-block is closed. The plunger is spring-pressed to project it, and it operates through a suitable guide 9 and has its rear end connected to a link g, and the link in turn is pivoted to a lever 9 which has its lower end provided with a cross-pin g.

The breech-block B has on its side the grooves B, which extend approximately parallel with the lower edge thereof for a portion of their distance and then depend and merge with the said lower edge, and it is in these slots that the studs 6 of the fingers of the carrier travel with the reciprocation of the breech-block, the said fingers being forced downwardly by the walls of the grooves into the position shown in Fig. 2. The groove B is not shown in Fig. 2 for the reason that the side plate L obstructs the view thereof. It is to be understood, however, that each side of the block B has a groove B After the said fingers have been depressed until the studs are disengaged from the walls of the groove a spring-guard B snaps into place and covers the groove at its point of mere ger with the lower edge of the breech-block. The guard is anchored at one end to the breech-block and is preferably set in flush with the lower surface of the said breechblock. Vith the reciprocation of the breech block, as stated, the fingers are depressed, thus elevating the opposite end of the carrier, which movement results in elevating the shell from the horizontal position in which it is received from the magazine toan inclined position, with its end directed to the breech of the barrel. With the closing of the breech-block the shell is forced into the barrel and the carrier is depressed to an approximately horizontal position and on a plane with the lower wall of the magazine.

An ejector-pin H projects into one side of the receiver, and the breech-block has a longitudinal channel 7'. to form a way so that the said breech-block may travelpast the stud or pin.

The action-rod J is slidable in a longitudinal groove in the bottom of the receiver, and the rear end of said action-rod carries an arm J, which flares upwardly and has a camming-surface j, over which the cross-pin of the lever rides as the said arm is forced rearwardly by the action-rod, and as the said lever is forced rearwardly on its pivot the plunger is reset.

The rear end of the breech-block has ears K, between which the link L is pivoted, one end of the said linkbeing pivoted to the arm J in order to take motion therefrom. The arm J is bifurcated from its upper edge toward the bottom, and the link has its end pivoted in the bifurcation. The outer end of the link is flared and one corner thereof is pivoted to the ears K of the breech-block, as fully illustrated. In operation as the action rod draws the arm J inwardly toward the breech-block the said breech-block is carried up the inclined way formed by the shoulders (1, thus elevating the pivotal point of the link where it connects to the ears K above the pivotal point of the said link where it is connected to the arm. Hence as the parts move toward the breech of the barrel and the breech-block has reached its limit of movement in that direction further pull on the action-rod would result in the link swinging upwardly on its pivots, and thereby car rying the rear end of the breech-block to the plane of the front end thereof and causing the said breech-block to assume a position in the plane of the barrel, where it is held against displacement through the medium of the arm With the rearward thrust of the action-rod the link carries the rear end of the breechblock down to an inclined position, where it rests on the shoulders a and is slidable thereon.

The breech-block has side plates L and M, which project beyond the end of the breechblock, the said plate L having a shoulder in its inner face, the said shoulder standing at an. angle with relation to the end of. the breech-block, so that the space between the shoulder and the end of the breech-block is restrictedat the bottom and becomes a little larger toward the top, and this is provided for the purpose of allowin a limited move- ,ment of the flange of ashefl in order that the said shell may swing vertically without the flange of the shell being bound between the shoulder and the end of the breech-block.

The plate M, which projects beyond the end of the breech-block, has a lug m at its lower corner, which is designed for the purpose of engaging the flange of the shell to coact with the shoulder of the plate L in moving the said shell.

The fin N is arranged on the breech-block and depends therefrom longitudinally and is preferably formed integral with the said breech-block. The fin is slidable between the guides formed by slotting the shell-delivering device, and it is also slidable between the lifter-fingers, which lifter-fingers, by the way, have the purpose of elevating the rear portion of the shell, so that the said portion will be on the plane of the front portion at the time it is delivered to the barrel. The fin is tapered in depth from the front of the breech-block toward the rear and terminates about centrally the length of the said,

breech-block. This arrangement assures the return of the lifter-fingers to their normal po sition.

By the rearward motion of the breechblock the shell is drawn back or extracted from the barrel and comes into contact with the pin H and is ejected before the carrier is raised, thus allowing room for the next shell. The lifter-fingers take no action except in the forward motion of the breech-block. During the rearward thrust the flange of the shell is pressed against the plate m by the plate Z with suificient force to hold it from dropping until it is ejected by the pin. When there is a plurality of shells in the gun, each succeeding shell holds up the rear end of the shell that is being ejected.

The trigger O has a link P, which is con nected to a latch which holds the said lever 9 set when the plunger G-is retracted. The latch is normally pressed by the spring Q. A safety-catch R is slidable in a slot 1 and serves to retain the latch against movement when set to accomplish the result, though it may be moved out of engagement with the latch at will of an operator to permit firing of the gun.

The end of the lifter F is beveled and is adapted to engage the beveled ends of the blocks F, which are provided for holding the lifter normally parallel with the carrier and limiting the movement thereof in one direction.
