Lawranc M Endres Michael A-Enfli'Es LAWRENCE M. ENDRES AND MICHAEL A. ENDRES, 0F SPRINGFIELD CORNERS, WISCONSIN.

, CARTRIDGE MAGAZINE.

To all whom it may concern:

Be it known that we, LAWRENCE M. EN- nnns and MrCHAnLA. ENDREs, both citizens of the United States, and residents of Springfield Corners, in the county of Dane and State of l/Visconsin, have invented certain new and useful Improvements in Cartridge Magazines; and we do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to an improved cartridge magazine, which is adapted for use in connection with small firearms, and more especially to those which are not self-load- 1n in important object of the invention is to provide a magazine which may be attached to a small firearm, and made a permanent part of the same.

A more particular object of the invention is to provide a convenient device for carrying a supply of ammunition where it will be conveniently available so that there may r be no delay in reloading.

A more specific object of the invention is to provide a device wherein the cartridge is suspended where it may be quickly grasped by the user, and wherein as soon as the cartridge is removed another cartridge will take its place.

In describing our invention, reference may be had to the accompanying drawings, in which:

Figure 1 is a side elevation of the device attached to the rifle.

Figure 2 is an elevation partlyin section of the magazine, and

Figure 3 is a detail sectional view showing the retaining spring and the slot through which the cartridges pass.

Referring now to the drawings more in detail, the magazine comprises a cylindrical barrel 5 to which the attaching plates 6 and 7 are secured by fusing or other means, and which are secured in any convenient manner to the barrel 8 of a small firearm.

The barrel 5 is made of a size to conveniently receive the cartridges or shells in longitudinal relation, and it is made of a length to extend from the stock nearly to the muzzle of the firearm. The barrel 5 at the end near the stock is closed as shown at 9, and on the side opposite to the firearm barrel and near the end 9 it is provided with a keyhole slotlO, the narrow portion of which is of a Specification of Letters Patent.

size to permit the body of the cartridge to drop through as shown at 11, but not wide enough for the rim to pass therethrough.

The enlarged portion 12 of the keyhole slot is of a size suflicient to allow the rim of theucartridge to pass therethrough, as shown at In the end of the barrel 5 is a coil spring 14, with its projecting ends engaging the barrel at 15. At the other side of the coil a spring projects parallel and in close relation with the keyhole slot, and is bent upwardly to form a tongue 17 The opposite end of the barrel 5 is formed with flanges 18 or the like to partially close the end to prevent the cartridges from passing therethrough.

It will be readily understood that the magazine may be loaded by inserting the cartridges or shells rim first through the hole 12, sliding the same along to the position shown at 11 in Figure 2 past the tongue 17 t The cartridge may then be turned to the right and slid up into the barrel. In using the firearm it will be seen that the cartridge nearest the keyhole slot will readily drop down into the position as shown at 11, and be retained in this position by the spring 14.

When it is desired to reload the firearm, the cartridge may be readily slipped out through the hole 12, the cartridge being normally retained by the spring.

We claim as our invention:

1. In a device of the character described, a cylindrical barrel having a keyhole slot in the side thereof near one end, a spring secured within the barrel with a portion tlliereof yieldingly held in proximity to said s 0t.

2. In a device of the character described, a cylindrical barrel having a keyhole slot in the side thereof near one end, the enlarged portion of the slot being nearest the end and the sides of the smaller portion of the slot extending parallel with the axis of said barrel, and a spring secured within the barrel with a portion thereof yieldingly held in proximity to the narrow portion of the slot.

3. In a device of the character described, a cylindrical barrel having a keyhole slot in the side thereof near one end, the enlarged portion of the slot being nearest the end and the sides of the smaller portion of the slot extending parallel with the axis of said barrel a spring secured to the end of said barrel with a portion thereof projecting in close proximity to said slot, and toward the smaller end thereof, the end of said projecting portion being bent to extend obliquely toward the other side of the barrel.

4. In a device of the character described, a cylindrical barrel having a keyhole slot in the side thereof near one end, a spring secured to the end of said barrel with a portion thereof projecting in close proximity to said slot and extending toward the smaller end thereof, the end of said projecting portion being bent to extend obliquely toward the other side of the barrel, and means for attachin said barrel to the barrel of a small firearm in parallel relation thereto.

In testimony that we claim the foregoing we have hereunto set our hands at Dane,-in the county of Dane and State of Wisconsin.
