PATENT REUBEN S. OHAFFEE, OF SPRINGFIELD, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 314,515, dated March 24, 1885.

Application filed February 9. 1883. Rencwtd April 22, 1884. Again renewed December 1:1, 1884. (No model.)

To (LZZ whom it may concern..-

Be itknown that I, R. S. CHAFFEE,OfSpringfield, in the county of Sangainon and State of Illinois, have invented certain new and useful Improvements in Feeding Mechanism for Breech'Loading Fire-Arms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it per tains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in breech-loading fire-arms, and is intended as an improvement upon an application filed by me December 5, 1881; and it consists, first, in the combination of the loading-bars, one of e which has a suitable projection formed upon its front end,with a grooved plate, which is secured to the side of the receiver,with a pivoted shifting device, whereby the loading-bar, having a projection on its front end, may be connected to and disconnected from the cartridge-extractor; second, in the peculiar con-' struction of the loading-bars, whereby the end wise movement of the central bar is made to depress the two ratchet-bars, so as to allow the cartridges to be slipped freely in; third, in the arrangement and combination of parts, which will be more fully described hereinafter.

The main object of my invention is to provide a means for connecting the loading-bars to and disconnecting them from a cartridge extractor attached to the fiIlDgbOliI', the means being held stationary upon the gun instead of being made to move back and forth with the firing-bolt, as shown and described in my for mer application.

Figure 1 is a side elevation of my invention, the stock being removed so as to show the con necting parts. Figs. 2 and 3 are detached views of the grooved plate. Figs. 4. 5, 6, 7, 8, 13, and 14 are detached views ofthe loadingbars. Figs. 9, 10, 11, 12, 15, 16, 17, and 18 are detail views of the cartridge-extractor and the plate for locking the front end of the loading-bar to the extractor.

With the exception of the parts hereinafter described, the gun is the same or very similar to what is shown in my former application,

I and therefore need not be more fully described in this application.

As in the former application, the cartridgeextractor A is removably attached to the front end of the firing-bolt B, so as to be carried back and forth therewith. This cartridge-extractor has an arm, 0, projecting down outside of the receiver, for the purpose of engaging with the front end of the loading-bar D, which has a projection, E, formed upon one side.

Secured to the side ofthe receiver is the plate F, which is provided on its inner side with the grooves G H, in which the front end of the loading-bar I) and thelocking-plate L are made to move back and forth by the movement of the firing-bolt B. The arm 0 ofthe cartridgeextractor extends down in between this plate and the side of the receiver, and engages with the projection E on the front end of the load ing-bar D when it is desired to connect the firingbolt with the magazine. \Vhen, however, it is desired to use the gun as a singleloader, the arm 0 will slide freely back and forth with the firing-bolt without interfering with the loading-bar in any manner.

The notch in the front edge of the arm 0 i comesjust opposite the lower groove, H, and it is at this point that the frontend of the loading-har D is locked to the arm G by the plate L. When the arm 0 and the front end of the loading-bar D are not locked together, the plate L is moved above the projection E, as shown in dotted lines in Fig. 16, and then, when the arm G is carried backward by the movement of the firing-bolt B, the front end of the loading-bar I) remains stationary at the front end of the groove H. \Vhen the locking-plate L IS depressed below the groove G, it catches over the front edge of the projection E, as shown in Fig. 16, and locks the firingbolt D to the front edge of the arm 0. Then, when the arm 0 is moved back and forth by the firing-bolt, both the locking-plate L and the front end of the loading-bar D are carried with it. Vhen the locking-plate L is raised in the position shown in Fig. 16, it is moved back and forth in the groove G by the arm 0 without operatin g the loading-bars. This shifting vertically of the plate L and unlocking of the front end of the loading-bar O can only take place at the ICU front end of the grooved casting, where the shifting device I is located. The connection between the arm 0 and the front end of the loading-bar D takes place in front ofthe groove H, because when the plate L is moved upward by the shifting device I opposite the groove G the plate L moves beyond the notch in the front edge of the arm 0, and hence there is nothing to lock the two parts together. WVhile the plate L is opposite to the groove G the plate L is carried back and forth with the arm 0; but the loading-bar D remains, stationary, ready to be connected to the arm 0 whenever it is desired to throw the magazine into operation by forcing the plate L downward again. The front end of the loading-bar remains in position at the front end of the slot H, ready to be connected to the arm 0 at any time.

For the purpose of connecting and disconnecting the loading-bar D and the cartridgeextractor, which is carried back and forth by the bolt, there is pivoted between the front end of the plate and. the side of the receiver a shifting plate or device, I. The upper end of this shifting device forms a simple projection against which the fingers can be made to catch for the purpose of moving the device back and forth upon its pivot, while its lower end projects backward a suitable dis tance, and has a recess, J, made in it. This recess J catches over the projection K, which is made upon thelocking-plate L. This plate L has its side cut away atom of its ends, as shown at M, and is forced to move up and down before the front ends of the grooves G H. Nhen the upper end of the shifting device is forced forward, it raises the lockingplate L in front of the upper groove, G, and the projection E upon the front end of the loading-bar D having nothing to lock it in the notch in the front end of the arm G on the cartridge-extractor, the loading-bar is no longer moved back and forth with the firingbolt for the purpose of throwing into opera tion the magazine. When, however, the front end of the shifting device I is moved backward, and the recess J forces the plate L downward opposite the lower groove, the plate, by means of the recess M, serves to lock the front end of the loading-bar D and the cartridge-extractor together, and thus throwing the magazine into operation. For the purpose of holding the shifting device I in any position in which it may be adjusted, the spring N is applied to the outer side of the plate F, and this spring has a small projection, 2, which passes through the side of the plate and catches against the shifting device I, so as to hold it in any position into which it may be adjusted.

The great advantage of a shifting device which remains stationary while the firingbolt is being moved back and forth consists in that the device is not likely to become disconnected from the loading-bar, and is not in the way of the person handling the gun.

In the magazine there are the two ratchet or loading bars D O and the central rod, P, which is connected with and operated by the breech-plate, as described in my former application. The difference in the construction here shown and that shown in my former application consists in the construction of the lower side of the rod P. As each of the loading or ratchet bars D O has suitable projections, Q, which catch against the under side of the rod P when the rod P is moved endwise by the opening of the breech-plate, these projections are brought in contact with the inclines R, formed on the under side of the rod P, and these inclines force the bars D O downward, so that their upper edges will not project above the top of the rod P, and thus allow the cartridges to be poured freely into the magazine, The ratchet-bar O has no other movement than a rising and falling one in relation to the rod P, while the ratchet-bar D is carried back and forth with the firing-bolt for the purpose of moving the cartridges forward. The projections Q, upon this ratchet-rod D differ slightly in form from those upon the rod 0, and the rod P has the shoulder or shoulders S formed upon it for thepurpose of stopping the movement of the rod D.

The two braces D O are held braced upward, so that their upper edges will project above the top of the rod P by the two springs T. These springs have their ends formed into prongs, and the prongs then bear upon the rods D 0 without touching the rod P. One of the springs is provided with four prongs, while the other has but two; but both springs are provided with aprojection, V, which snaps into the opening made through the bottom of the magazine-tube to receive them. By forming these projections V upon the springs they have but to be pushed into place, and there they are held without the use-of screws or other fastening devices, which have to be re moved whenever it is desired to remove the loading bars or ratchets.
