Application filed J'anuary4, 1917. 'S eri alNo.140,53Q.

To all whom/ it may concern:

Be it known that I, LOUIS WESLEY H n- GEN-DORE, a citizen of the'United States, and a resident of Fountain, in the county of .El Paso and State of Colorado, have invented certain new and useful Improvements in *Oartridg e-Magazines, of which the following is a specification.

My invention relates'to firearms, of the repeater type, and the'main object thereof is to double the magazine capacity and to provide simple though efficient means for instantly and automatically throwing an exhausted portion of the magazine outof.

operative position and moving the unused stack of cart-ridges into operative position.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which :like characters refer to like parts in each of the yiews, and in which Figure 1 is a side elevation of a firearm, partly in section, provided with my invention; r

magazine shown in section;

Fig. 3 is a view similar to Fg. 2 but showing the cartridges shown in F ig. 2 asall ejected to permit the magazine movement to bring the other cartridge stack into operative, position; 7

Fig. 4 is av section taken on the line 4-1 of Fig. 2, showing the initial cartridge stack in operative position;

Fig. 5 is a section taken on the line 55 of Fig. 3, showing the second cartridge stack in operative position; and

. Fig. 6 is a fragmentary interior view of the firearm, as on'the line 6'6 of Fig. 1.

Referring to the drawings, 7 represents a firearm having 'a magazine receiving space 8 and a barrel 9, no effort having been made to illustrate the firing mechanism, nor the ejecting mechanism, as they form nopa'rt of my invention, but attention is drawn to an inclined groove 10 at the forward portion of the space 8 cut-into the frame of the firearm. r

Vertically, slidable upwardly into the space 8, isa magazine 11 plvoted at 12 to a base plate 13 and having a central parti tion 14 forming two com artments' 15 and 16'for separate stacks 1 and 18 of car tridges, each stack being moved upwardly I therefor, means engaged in said groove for by means of a spring 19 and follower 20 the latter of which has an lnclmed free end 21 adapted, when forced downwardly by the introduction of the cartridges in. the compartment 15, to force aspring bar 22 forwardly of saidcompartment whereby a button 23 thereon is forced outwardly 1 through a suitable opening in the front wall of said compartment, the cartridges in said compartment preventing rearward move- I Fig.2 is a similar view with the cartridge ment of said springbar 22.

When the magazine is introduced into the space 8 the forwardly forced button 23 enters the inclined groove 10 and rocks the magazine upon its pivot 12 against the action ofa spring. 24 into the position shown in Fig. 4, whereby the upper cartridge in the stack 17 is "in line for movement into firing position and subsequent ejection, all of' the cartridges in this stack being'succes- 'sively discharged and ejected in the usual way and, when the compartment 15 is entirely empty of cartridges,"there is nothing to ,prevent retraction of the spring bar22 to draw the button 23 outof the groove 10 in which 'it had .restedhitherto.

Upon suchretraction of the button 23,

the spring 24: forces the magazine into the position shown in Fig. 5 to present thecartridges in the stack 18 successively to the firing and ejecting mechanisms and, upon the exhausting of this stack,- the magazine .may be withdrawn frorn the firearm and refilled, it being noted that the button 23 is positively moved into groove engaging po- "sition as long as there-is one, or more, car tridges in the compartment15 and is positively retracted when this compartment is emptied, the action. of said button thus being entirely ,under the controlv of the cartridges in the compartment 15.

My inventionis very simple and, with the mer'eaddition of the groove 10 to the firearm, is readily adapted to arms of difierent types and makes, and I reserve the right to make such structural changes over the form shown and described as properly come within'the spirit ofmy invention and within the scope of he appended claims.

Havin fully described my invention, what I claim as new, and desire to secure byLetters Patent, is-:-

1. In a firearm having a magazine receiving space and a groove at one endvof said space; a magazine divided into a plurality of cartridge compartments, a pivotal mount bringing one of said compartments into ca!- the cartridges in one compartment for carrying the same into cartridge feeding position, and automatic means operable upon the exhaustion of said last named compartment for bringing the other compartment into cartridge feeding position.

3. In a firearm having a magazine receiving space and a groove at one end ofsaid space; a rockable magazine divided into two cartridge compartments, means controlled the cartridges in one compartmentand operable in said groove for bringing said compartment into cartridge feeding position, and automatic means operable upon the exhaustion of said last named compartment for bringing the other compartment into cartridge feeding position.

4. In a firearm having a magazine receiv-' 111g space and a groove at one end thereof; a

rockable magazine divided. into two cartridge compartments, a spring retracted button forced into groove engagement by the cartridges in one of said compartments, and

Ya spring for rocln'ng said magazine on its pivot to bring the other compartment into cartridge feeding position upon the exhaustion of said previously named compartment and upon the retraction of said button out of groove engagement.

5. In a firearm having a magazine receiving space and a groove at one end thereof; a rockable magazine divided into compartments, a spring bar in one compartment; a button thereon, said button being forced outwardly of said magazine to engagement with said groove upon the insertion of cartridges into said compartment and held in such position until said compartment is emptied of cartridges to permit said bar to retract said button, and a laterally operable spring for rocking said magazine .to bring the other compartment into cartridge feeding position upon the wretraction of said button.

6. As an article of manufacture, for use in a firearm, a two compartment magazine, a support therefor. a pivotal connection therefor, a'- spring controlled follower in each compartment, a spring bar secured in one compartment adapted to be forced toward the end of said compartment upon the depression of the respective follower by the introduction of cartridges, and a button on said bar held outwardly of said magazine while said last named compartment contains a cartridge.
