REPEATING- FIREARM.

To all whom it may concern:

Be it known that I, ED\VARD E. REDFIELD, a citizen of the United States, residing at Glendale, Douglas county, Oregon, have invented certain new and useful Improvements in Repeating Firearms, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention has been developed with especial reference to its application to repeating firearms in which the frame is closed in the rear of the breech, but as the description thereof proceeds it will be seen that the improvements, at least except so far as they involve directly a closed frame, are applicable, either separately or together, to other forms of repeating firearms.

One object of the invention is to permit the use of an external hammer with a closed frame, and thereby to avoid the dangers of a concealed hammer, and also to permit the cooking of the hammer to be effected directly by the action of the guard lever, either in connection with the closed frame or in connection with a rearwardly sliding breechblock, the cooking of the hammer being thereby more easily effected, since the full stroke of the guard lever may be utilized for the purpose without lost motion.

Another feature of the invention is particularly concerned with means for efiecting the movement of the breech-block from the firing position to the loading position and from the loading position to the firing position, and for looking it in the firing position,

such means being especially adapted for use,

with a closed frame.

The invention is also concerned with means for extracting the empty shell from the chamber of the barrel after firing and for ejecting it from the frame or receiver, such means being carried by the breechblock.

The means for operating the cartridge carrier or lifter, by which each cartridge as it is received from the magazine is moved to position for insertion in the chamber of the barrel, are also improved, the purpose being to secure more direct and positive action, as well as more power. The operation of the cartridge guide, or cartridge plate, by which the cartridge ispreventedfrom falling out through the ejector opening during the loading movement, has also been improved.

These and other details and features of improvement will be more fully explained hereinafter with reference to the accompanying drawings, in which an embodiment of the invention is illustrated, and in which- Figure 1 is a view in side elevation of an ordinary sporting rifle, to which the invention is applied. Fig. 2 is a detail view on a larger scale, partly in side elevation and partly in longitudinal section, of so much of the rifle shown in Fig. 1 as is necessary to enable the application of the invention to be understood, the parts being shown in the firing position, but with the hammer down. Fig. 3 is a view in section on the plane indi cated by the broken line 33 in Fig. 2, looking in the direction of the arrows. Fig. t is a view similar toFig. 2, but with the parts in the positions which they assume during the operation of the loading, the cartridge being shown on the carrier in readiness to be inserted in the chamber of the barrel. Fig. 5 is a detail "iew in section on the plane indicated by the line 5-5 in Fig. 4., looking in the direction of the arrows. Fig. 6 is a view generally similar to Figs. 2 and a, but with the parts in the positions which they assume in the beginning of the downward movement of the guard lever after the firing. Figs. 7 and 8 are detail views, partly in horizontal section and partly in plan view, showing particularly the cartridge extracting and ejectingdevices. Fig. 9 is a detail view, in front end elevation, of the breech block. Figs. 10, 11 and 12 are detail views, respectively, of the cartridge carrier or lifter, the lifting slide for the breechblock and the guard lever, the latter being broken off to save space.

The barrel a chambered as at a to receive the cartridge, the magazine Z) in which the cartridges are placed and are pressed to the rear by a spring follower not shown, the frame or receiver 0 (except as hereinafter indicated) and the stock (Z may all be con 190 structed and arranged in any usual or convenient manner.

In the type of firearm with which the invention is particularly concerned, the frame or receiver 0 is closed, i. 6., itis provided 105 ably chambered as at 0 to permit'the proper 110 movement of the breech-block and other parts, as hereinafter explained. The breechblock e, as is usual in firearms of the type referred to, during the extraction and ejection of the empty cartridge shell, and during the loading movement, first drops down from its firing position between the barrel and the abutment of the frame, then moves back to permit the cartridge to be placed in front of it, then moves forward to insert the cartridge in the chamber of the barrel, and then rises to the firing position. The guard lever f, as also usual in repeating firearms, swings upon a pivot f in the underside of the frame, its movement effecting the various operations of extracting the empty cartridge shell, cocking the hammer, lifting the fresh cartridge into position, and inserting the cartridge into the chamber of the barrel. The devices through which these various operations are effected, differ, however, from those heretofore employed, as will now be described.

The breech-block c has in its left-hand side a longitudinal groove 6 (see particularly Figs. 3 and 6) which is entered by a pin g (Figs. 3, 6 and 11), on the right-hand side of the breech-block lifter g. The latter has a vertical movement, being guided in the recess in the left-hand side of the frame or receiver. Its lower end is provided with a lug g projected to the right and also to the rear, to be engaged by a forwardly projected hook or finger on the guard lever f in rear of the pivot f, and when the guard lever is in its normal position, as shown in Fig. 2, standing above the horizontal plane of the pivot f when the rifle is held with its barrel horizontal. During the first part of the downward movement of the rear end of the guard lever the hook f pulls down the breech-block lifter 9 through its engagement with the lug 9 as shown in Fig. 6, and as such movement continues and the hook or t 45 {i nger reaches the horizontal plane of the pivot f" it is disengaged from the lug so that the downward movement of the lifter g ceases and the movement of the guard lever f is permitted to continue. The downward movement of the lifter g is sufiicient to depress the rear end of the breech block 6 below the abutment 0 so that the breech-block is then free to move rearwardly. Such rear ward movement of the breecl1block is effected by the continued movement of the guard lever f, which is extended forward beyond the pivot f and is provided with a finger which is preferably rounded and enters a slot 6 (Figs. 2, 3 and 6) of the breech-block e near its forward end. The continued downward and forward movement of the rear end of the guard lever f through the forwardly extended finger 7 causes the rearward movement of the breech block 6 from the position shown in Figs. 2 and 6 to the position shown l in Fig. i, in which the breech block is represented in its extreme rearward position. The upward and rearward movement of the rear end of the guard lever f first moves the breech block forward from the position shown in Fig. 4 to the position shown in Fig. (3 and then through contact of the upper side of the guard lever wit-h the under side I of the lifter g raises the rear end of the breech block from the position shown in Fig. 6 to the position shown in Fig. 2, in which it is in readiness for firing. In the upward movement of the guard lever the hook or finger 7 again engages the lug of the slide g in readiness for the next downward movement of the breech block.

The cartridge lifter or carrier 71, suitably shaped at its forward end to receive the fresh cartridge from the magazine, is pivoted near its rear end as upon the pin it and at its rear end, as at it is formed with an upwardly turned toe with which the rear end of the breech block a cooperates as the breech block reaches the limit of its rearward move ment, as shown in Fig. 4, with a direct, positive, and wedge-like or cam-like action, to tilt the carrier upon its pivot, raising its forward end with the cartridge thereon into the position shown in Fig. 4. The initial movement of the cartridge lifter or carrier, however, is effected as heretofore, the guard lever 7 being formed forward and above its pivot f with a cam toe 7, which acts against the under side of the cartridge lifter or carrier h to start the same from its initial position of rest, such initial movement raising the end of the carrier sufficiently to act as a magazine cut-off to prevent the egress of another cartridge from the magazine. The I main part of the movement of the carrier is effected by the cooperation of the breech block with the cam toe [L2, as above described.

On the right hand side of the cartridge lifter is pivoted a cartridge guide or guard plate 2', the rear end of which is wider than the cartridge lifter or carrier. As the car tridge carrier is swung upward on its pivot in the manner described, that portion 2" of the rear end of the cartridge guide which projects above the cartridge carrier strikes the overlying breech block 6, as shown in Fig. 4;, throwing down the rear end of the cartridge guide and raising the forward end. This movement takes place as the cartridge is raised to the level of the ejector opening 0 in the right hand side of the frame, so that the cartridge is prevented from falling out through such opening, even if the rifle is held in a position in which this would otherwise be possible.

As before stated,t-he hammer is is an ranged as an external hammer, notwithstanding the factthat the frame is closed at the rear. As shown, the hammer is pivoted in the frame as usual, as on the pin h,

and it co-acts directly with the rear member 7a of the firing pin which is seated in the abutment 0 of the frame and is pressed to the rear by a spring In view of the movement of the breech block relative to the frame in which the member is of the firing pin is mounted. it is necessary to make the firing pin in two parts, the other part k (Figs. 2 and 3) being mounted in the breech block 6 and having its reduced forward end extended through the face of the breech block as usual to act upon the primer of the cartridge.

The hammer is cocked directly through the movement of the guard lever f, the cocking bar 70 being pivoted on the guard lever above its pivot f and cooperating with a shoulder 7:: of the hammer during the movement of the guard lever to open the breech, and thus cooking the hammer against the force of the main spring is, the hammer being held in cocked position by the sear 71: of the trigger 2 or by other usual or suitable means. It will be seen not only that the hammer is exposed, which is more desirable on the score of safety than a concealed hammer, but that it is cooked directly by the movement of the guard lever, the cocking movement of the hammer taking place practically throughout the entire movement of the guard lever, so that the cocking is easily effected. The breech block does not touch the hammer during its movement, being slotted on its under side and at its rear end, as at 0*, to straddle the hammer in its rearward movement, this arrangement permitting the use of a shorter receiver or frame than would otherwise be possible.

The extraction of the empty cartridge shell from the chamber of the barrel and the ejection thereof through the opening 0 in the side of theframe are accomplished in the following manner: In opposite sides of the breech block 6, at its forward end, are pivoted two levers Z and m formed at their forward ends to engage the rim of the cartridge, as shown in Fig. 7. The lever 1 serves the purpose of an extractor only and is held yieldingly in normal position by the spring Z as usual. The lever m serves the double purpose of an extractor and an ejector. This is not spring-pressed, but its tail on stands in the groove 6 (Figs. 5, 7 and 8) in the left hand side of the breechblock. In the rear portion of the groove 6 is a lug or pin, such as the pin g, which cooperates with the cam-like tail m of the extractor-ejector to cause the same to be rocked upon its pivot, as shown in Fig. 8, the frame 0 being recessed, as at 0*, to receive the hook member of the lever during this movement. The ejector member of the lever consists of an arm m which lies in a slot formed therefor in the parts of the breech-block and extends nearly across the head of the cartridge, so that when the tail of the lever strikes the lug or pin g the ejector arm is thrown quickly into the position shown in Fig. 8, while at the same time the hook member is disengaged from the rim of the cartridge. This action causes the cartridge to be ejected through the ejector opening 0 in the frame with a quick snap, which throws it clear of the frame.

The general mode of operation of the improved firearm is substantially the same as that of any other firearm of like character, and need not be described in detail herein, the features of operation with which the present invention is concerned having been fully described andexplained.

It has already been suggested and it will now be evident that certain features of the present improvement, such, for example, as the cartridge lifting devices, the cocking devices and the extracting and ejecting devices, are not necessarily employed in connection with a closed or solid frame, and it will also be evident that such devices are not necessarily combined with one another in a single'structure, since each of such devices may be used with other devices than those shown and described. It will further be evident that the invention is not limited to the particular details of construction and arrangement shown and described herein.
