ERNEST JAMES HISCOCK, OF HYTI-IE, ENGLAND.

MAGAZINE FOR MINIATURE AMMUNITION FOR RIFLES.

Application filed December 30, 1912.

To all whom it may concern:

Be it known that I, Ermnsr JAMns Hrs- COCK, a subject of the King of Great Britain, residing at the School of Musketry, Hythe, Kent, England, have invented a new and useful Magazine for Miniature Ammunition for Rifles, of which the following is a speci fication.

My invention has for its object to provide means whereby fire arms having a bolt action, such, for instance, as the rifle known as the Lee magazine rifle, and which have been converted for use with .22 inch rim fire cartridges or other miniature ammunition, for firing practice at miniature rifle ranges, instead of being loaded by hand, can be automatically loaded by the operation of the bolt, thereby permitting of rapid firing.

According to the invention I provide a detachable magazine which is designed to be introduced into the ordinary magazine chamber in the rifle, and which isso arranged that the cartridges will be pushed from the magazine by the ordinary bolt adapted, for say, .303 inch or other ammunition such as is now generally used in a service rifle.

The magazine constructed according to my invention is provided with a case for containing the miniature ammunition and with a spring charging plunger carried on a platform or body part and adapted to be engaged by the rifle bolt, the said body part being constructed so that when the said plunger has been pushed forward to inserta cartridge into the chamber of the rifle, the whole of the magazine will be depressed so as to allow the bolt to pass above the same to force the cartridge home into the chamber and support it during firing.

My invention will be readily understood by reference to the accompanying drawing, in which Figure 1 is a sectional view of my improved magazine, Fig. 2 a plan, and Fig. 3 a front view thereof. Fig. 4 is a sectional side view showing the improved magazine applied in the magazine chamber of the gun, the breech being open, and Fig. 5 is a similar view showing the breech closed and the magazine depressed.

a indicates the case or magazine proper in which the miniature ammunition is stored, the said case being preferably made by bending a plate of sheet steel around a mandrel and brazing the adjacent edges on the rear side, a strengthening strip 6 being Specification of Letters Patent.

provided around the upper part. This case, which is advantageously adapted to contain 10 cartridges, has within it a spring 0, which at the lower end bears upon a plate (Z, the said plate being made removable so as to allow of inserting the spring and removing it when required. At the upper part of the magazine the lateral walls are bent over to form stops 6, e, 6 6 for retaining the cartridges in the magazine against the pressure of the spring 0, when charging the magazine, and alid 7 is pivoted to the top of the case to support the cartridges as they are pushed from the magazine through the hole 7.

g is the body portion of the magazine which is preferably made of cast steel and drilled or recessed to receive a plunger it preferably also of cast steel which is surrounded by a spring a to normally hold the plunger in a position with its head against a stop screwed into the body. The body 9 is brazed or otherwise firmly fixed to the case a so that the plunger it can pass through a hole 70 in the latter, opposite to the hole f in order to push the uppermost cartridge out of the case a through the hole F.

The case a with the body 9 is designed to be inserted into the usual magazine chamber of the rifle in the manner shown in Fig. 4, a steel spring Z of zig-zag or other suitable form being placed in the said chamber beneath the body 9, and serving to normally press the magazine as a whole upward, a stop a secured to the case a bearing against the underside of a plate a brazed into the trigger guard of the rifle in a manner clearly shown in Fig. 4. The upper surface of the body 9 is formed with inclines 0, 0 and is cut away at the rear of these inclines in such a manner that the upper part of the plunger h is uncovered so that the bolt m will engage with it as will be clearly understood by reference to Fig. 4. With this arrangement when the magazine is charged and the breech of the gun is open as shown in Fig. 4, the breech bolt m when pushed forward will come into contact with the plunger h and push the latter into the magazine case, and at the same time push therefrom the uppermost cartridge through the hole 7' so that the front portion of the cartridge enters the chamber 1?, until within about 3; of an inch of being pressed home, the remaining cartridges being pushed up by the spring a. As the forward movement of the bolt m is continued the latter by coming into contact with the inclines 0, 0 of the body releases the plunger k and pushes the whole magazine downward so that the bolt passes over the same and pushes the cartridge home into the chamber, as clearly shown in Fig. 5, while at the same time the plunger it moves rearwardly under the ac tion of its spring. After the cartridge in the barrel has been fired the bolt 7% is pulled back to extract the empty cartridge case the rim of which comes into contact with an upstanding lug or projection on the body 9 and V is thereby disengaged from the "usual extractor (not shown) on the bolt and 1. A magazine for miniature ammunition for a converted bolt rifle provided with a plunger for pushing the cart-ridges from the magazine designed to be operated by the bolt and adapted to be depressed to allow the bolt to pass over it, substantially as described.

2. In a magazine for miniature ammunition for converted bolt rifles the combination with a case or chamber for containing the ammunition, of a body part fixed to the said case, a plunger sliding in the body part and designed to be acted upon by the bolt of the rifle for pushing the uppermost cartridge through the case, a spring for supporting the body and case and means whereby the bolt of the rifle when pushed forward will push in the said plunger and depress the magazine, substantially as, and for the purpose, described.

8. A magazine for attachment to bolt rifles converted for use with miniature ammunition, comprising a case for containing the cartridges, a spring supported bodypart fixed to the said case, a spring plunger and an inclined part to engage the breechbolt to depress the magazine, after the cartridge has been forced out by the plunger, substantially as described.

t. The combination with a magazine for attachment to bolt rifles converted for use with miniature ammunition of a lug on the magazine designed to eject the empty cartridge case when the bolt is withdrawn, substantially as described.
