CARTRIDGE-MAGAZINE FOR AUTOMATIC-PISTOLS.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed October 16, 1916. Serial No, 125,960.

To all whom it may concern:

Be it known that I, WILLIAM CHARLES WALTER CoWLEs, a subject ofthe King of Great Britain and Ireland, residing at 72 King street, Sydney, in the State of New South Wales and Commonwealth of Australia, importer and manufacturer, have invented certain new and useful Improvements in Cartridge-Magazines for Automatic Pistols, of which the following is a specification.

This invention relates to improvements in the cartridge magazine of automatic pistols and the object of the invention is to facilitate the loading of same.

The magazines at present in use with this class of pistol are difficult to load, as each cartridge has to be inserted against the pressure of a spring, and this pressure increases as each cartridge is inserted, and further after the first cartridge has been inserted the spring pressure has to be overcome by pressing the rounded surface of the cartridge to be inserted against the rounded surface of the cartridge already in the magazine so that the process of loading is under certain circumstances difficult and tedious, and this invention is designed to overcome these defects by providing means to relieve the spring pressure while each cartridge is being inserted, such means being so applied to the magazine that no alteration is required in the magazine chamber in the pistol grip, so that the improved magazine can be substituted for those at present in use without any alteration whatever being made in the pistol.

A further improvement consists in the increased strength of the magazine table which obviates any chance of jambing through undue pressure being applied when loading, which sometimes occurs when an attempt is made to insert an extra cartridge.

But in order that the invention may be more clearly understood reference will now be made to the drawings which accompany and form part of this complete specification and in which Figure 1 is a side view of an empty magazine.

Fig. 2 is a similar view of the magazine loaded.

Fig. 3 is a similar view to Fig. 2 with a portion of one side wall removed.

Fig. 4 is a back view of magazine.

Fig. 5 is a side elevation of magazine table.

Fig. 6 is a section through line a. b. Fig. 5. Fig. 7 is an enlarged view of finger grips or buttons.

The metal casing 8 is of the ordinary shape and construction to receive the desired number of cartridges and to fit within the magazine receptacle in the handle of the pistol.

In a central position in each of the opposing side walls of the casing 8 a longitudinal slot 9 is cut, so that the edges of each slot are in alinement and form a through opening in the casing which opening extends from near the top to near the bottom as shown.

The casing 8 has Within it the usual box spring 10 on the top of which rests the cartridge table or platform 11 which is adapted to move freely up and down within the casing and consists of an angular box bracket on one member 12 of which is a bearing block 13 having an internally screw threaded hole 14 with an enlarged socket 15 at each end as shown in Figs. 5 and 6 of the drawings. When the table 11 is introduced into the casing 8 flat disks or buttons forming finger grips are secured to each side of the bearing block 13.

These disks or buttons are introduced through the longitudinal slots 9 in casing 8 and suitably secured to the table 11 by the screw threaded spindle 17 which may be an integral part of one of them as shown in Fig. 7. The buttons 16 when secured to the table 11 that is within the casing 8 are adapted to move in the slots 9 in each side of the casing, and when in position have their outer faces which are serrated or otherwise roughened flush with the outer faces of side walls of easing.

Referring to Fig. 7 of thedrawings which shows an enlarged view of the finger grips or buttons and connecting spindle.

The finger grips 16 which are preferably in the form of flat disks are of the same thickness as the walls of the casing 9 beyond which their outer faces do not project and have on their inner faces collars 18 which take into the socket 15 in bearing block 13 of table 11. One of the buttons may be integral with the spindle 17, or if desired the spindle may be separately screwed into the bearing block 13 and the buttons afterward screwed on the projecting ends thereof, or if desired the buttons may be squared and the projecting ends of 10&

the spindle slightly tapered and the' b-u'ttons secured thereon by pressure.

the other hand' and then further depresses the buttons and so on until the magazine is fully loaded.

' I claim 7 l.QMa;gazine for automatic pistols, com prising a metallic casing having slots in the side walls thereof, a platform movable within said casing, spring means tendingto ele- Copies of this patent'may be obtained for vate said platform, a 'member extending through an aperture provided. in said platform and grip membersgcomiectedito "the opposite ends of said member and lying within "said slots'.-
