EDWIN JAMES OASHMORE, OF TORONTO, CANADA.

MAGAZINE-GUN.

SPECIFICATION forming' part of Letters Patent No. 582,040, dated May 4, 1897.

Application filed January 13, 1896. Serial No. 575,285. (No model.)

To all whom it may con/cern,.-

Beit known that I, EDWIN JAMES 4CASH- MORE, gun-maker, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Sporting-Rifles, of which the following is a specification.

My invention relates to improvements in rifles; and the object of the invention is to provide a positive and elfectual means, not liable to get out of order, whereby the action may be only manipulated when the hammer is on the firing-pin, and at the same time provide for the throwing back ofl the hammer without the aid of the breech-block; and it consists,A essentially, of an operating-slide which is pivotallyT connected to a lever operatively connected to the breech-block and by a slotted link to the hammer, the parts being otherwise constructed in detail as hereinafter more particularly explained.

Figure 1 is a perspective sectional view of portion of a rifle, showing the parts involved in my invention, the breech-block being closed Aand. the hammer being on the ringpin. Fig. 2 is a similar View showing the hammer and breech-block thrown back.

,X f In the drawings like letters of reference in.

dicate corresponding parts in each figure.

A is the operating-slide, which is connected by the link B with alever C.

D is a link pivotally connected by the pin d to the lower end of the lever C. The other end of the link D has a slot d', into which extends a pin e from the side of the hammer E. The hammer is prgided with a spring F,- connected thereto in the usual manner.

Gr is the trigger, which is also provided with a spring g.

H is a breech-block which is provided with a plunger I, having the iiring-pin I at the inner end.

i is a pin extending across through a notch 'in the plunger.

I2 is a recess made in the plunger at each side, and .I is a spiral spring extending between the inner end of the plunger and the end of the recess J', in which the plunger fits.

j is a point formed in the plunger at the forward end of the recess I2 and designed to engage with the notch c at the upper end of the carrier, above the pivot-point 7c, is pro- .n

vided with the stop-lug 702, which is designed to engage with each end of an elongated recess h at the bottom of the breech-block H.

. M is the extractor, which is secured above the firing-pin and is provided with the usual hooked end.

Having now described the principal parts `involved in my invention, I shall brieiiy describe the operation.

The operating-slide A, upon being pushed forward slightly, throws the hammer E off the breech-block H by means of the link D, connected to the lever C and hammer, as hereinbefore described. On the operating-slide being pushed farther forward the locking-lever C engages with the rear end of the recess H of the sliding block H, thus throwing it back a suflicient distance to enable the extractor M to withdraw the cartridge from the chamber. At the same time the forward end of the recess H' engages with the lug k2, thereby tilting the carrier K, with its cartridge, until such cartridge is raised opposite the chamber of the barrel. In this position the carrier is held in place by the check-spring lo'. As a result of the above movement it, will of course be understood that the hammer is placed at fullcock. On pulling back the operating-slide A as far as possible the frontend of the lever C engages with the front end of the recess H of the breech-block, thereby throwingit forward and placing the cartridge in the chamber of the barrel. At the same instant the rear end of the recess h in the breech-block H engages with the lug k2 of the carrier K, thereby tilt. ing the carrier so that the forward end is depressed ready to receive another cartridge from the Imagazine. f

During the period that the carrier is being depressed thefforward end of the notch c ofV IOO the locking-lever C is engaged by the point j 'forcing the point j into the notch c. Upon the hammer E being caused to fall on the plunger I such hammer releases it from the notch c 1'n the lever C and thereby allows the above movement to be repeated.

By the construction above described it will be readily seen that the catch or lock for hold- -ing the operating-slide now commonly in use in other rifles will be entirely dispensed with.

The operation of my device is very positive and effectual, and upon the discharge of the rifle it will be seen that the operating-slide is pulled backwardly, which it is more natural to do than moving it forwardly, as is now commonly done.

What I claim as my invention-is l. In a rifle the combination with the foreend sliding breech-block, hammer, and trigger, of the locking-lever, the recess in the breech-block to receive the upper end of such lever, the link connecting the lower end to Athe operating-slide and means for connecting the hammer to the lower end of the lockinglever as and for the purpose specified. 2. In a riiie the combination with the foreend slidingbreech-block, hammer, and trigger, of the locking-lever therecess in the' breech-block to receive the upper end of such lever, the link connecting the lower end to the operating-slide and a link connecting the lower end of the locking-lever to the lower end of the hammer and the slot in such link as and for the purpose speciied.

3. In combination the barrel, the magazine, the breech-block, the locking-lever, the operating-slide having a link'connectionto the lower end of the locking-lever, the carrier 4 pivoted at the rear and liavinga central slot block,r the ends of which are designed to engage with the lug above the pivot-point of the carrier to tilt or depress it as speciiied.

5. The combination with the barrel and magazine, the breech-block,the locking-lcv er,

the operating-slide and the link connecting the operating-slide to the lower end of the` locking-lever, of the carrier having a central slot a lug at the rear upper end of the carrier and an elongated recess in the lower side of the breech-block and the spring arranged at right angles to said carrier for holding the same in tilted position, substantially as described. i

6. In combination the barrel, the magazine, the operating-slide, the locking-lever, the link connecting the operating-slide and lockinglever, the slotted breech-block, the upper end of the locking-lever extending thereinto, the

iirino-v in havino'a rearward ro'ection and a spring for pressing the projection into the recess whereby the end of the lever` is retained within the breech-block to receive the impact from the discharge and prevent the recoil of the block, substantially as described.

8. In combination, the barrel,the magazine, the breech-block having an elongated recess therein, the locking-lever, the operatin g-slide,

the link connecting the slide to the lockinglever, the carrier having a slot therein to permit the passage of said lever, a lug on the carrier projecting within the recess in the 'breech-block,and a vertically-arranged spring rigidly held at its lower end and havinga head on its upper end adapted to provide a seat for said carrier in the raised positie thereof, substantially as described. 9. 'In combination the breech-block, the lever intermediately pivoted, the operatingslide pivotally connected to they lower end of the lever, the hammer, the link pivota'llyA .ICO

connected to the lever below its pivot-point and'having a slotted end intov which extends a pin on the hammer below its pivot-point as specified.
