Claims; (Chem-5 6),

My invention referstoimprovements in rapid ,fireshoulder arms andiithas for-its primary'object to provide a means of utilizing commercially manufactured automatic pistols, or the like. for usevas rapidfire arms ,iforpolice-purposes. j 1

The ordinary automatic pistol consists, mainly, of a 'barrel mountedina frame, an automatic action, bymeans of which firing, extracting and ejecting the fired shell and the operations of loading the newcartridge from the magazine,,;is-ac-, complishedautomatically. 7 An object oftmy. invention ,is to provide means of supplying fixed ammunition-in greater numbers. than is ordinarily supplied .bythe convene tionahtype of magazineoriginally soldwitha pistol or the like. Thetransformed automatic pistol is fittedwith a magazine which is capable of containinga greaternumberof cartridges, and

bne which maybe readily adapted to the pistol Without alterations or. attachments made thereto. I shall describe the magazine in the follow& ing specifications.

The invention is shown by way of illustrati in the accompanying drawing,v wherein,

Fig. l is a partly sectionalized side view of the magazine.

Fig. 2 is a partly sectionalized rear view of the 24 having formed therein spiral compartments 25 which are formed by spiral walls 26. The compartments 25 have the same general dimensions as elongated tube 22. A spiral slot 2'7 is provided midway between the spiral walls 26;

A'fiexible follower (Fig. 5) consists of a series of cylindrical sections 28 securely fastened together by means of a steel Wire 29 threaded through each sectionat 30. The bottom follower 32 is provided with tapped holes 33 for the threaded ends'of guide pins 34. Thetop follower 35 has a contour on the top surface 35a similar to the top surface of the follower in the magazine furnished with thepistol. The follower thus described forms a fully flexible unit and will follow the spiral compartments of the V on hub .2' 7 Into thefree end of the spring E is yby'means of screws 45.

may have been placed into the elongated tube I'claim and desire to secure by Letters Patent magazines-without being disassembled. It is then 7 inserted inopening D- (Fig. 1) in elongated tube 22, the bottom section 32 entering first.

Guide pins 134 are inserted through the spiral slot 27. which.- prevent the followerassembly C :(Fig. 5) from'being forcedout through opening D of the elongated tube 22' by the action ,of the spring-E which I will describe later. v

' Integrally formed with'housing. 24 isjournal 36 which terminates in a hub 37 through which isboreda'hole 38 into'which is inserted a shaft .Ac'tuating'discs40 and 4i having elongated slotsf42 formed thereinareslipped over the ends of shaft 39'so that the elongated slots 42 are opposite and engage'guide pins 34 in'bottom section of follower32 of follower assembly C.

,"A spiralclock type spring E is secured at 37a placed pin ,43,.of c'over44jj Actuating disc-4d is then secured to. shaft 39 bypin 39a, Cover. 44 is similarly s'ecured to, shaft39 by pinBQa v The coveri'44isthenrotated clockwise to wind the spring-E; The followendis theirbrought down;

to'its lowest position in housing :24 by turning Y actuating disc 40 counter-clockwise until it stops.

The cover 44 is then secured to actuating disc 41 It is to be understood that when the follower is in its lowermost 'position in housing 24, the spring E must be fully 'wound, so that should the cover 44 be released the action of spring E will cause the follower assembly .C to travel thru the spiral compartments, thus forcing outwardly any, cartridges which 22 through opening D. To load the, magazine, the cover 44 is rotated. clockwise just slightly and a few cartridges placed on top of follower 35.. The operation is repeated until the magazine is filled. Should the top cartridge be carried into the chamber of the pistol by'the automatic -action, anothercartridge will be pressed into place by the action of the follower 35.

While certain features of my invention are more or less specifically illustrated, I wish it understood that various changes in form and proportion may be resorted to within the scope of the appended claims. I similarly wish it understood that the materials and the finish of the several parts employed maybe such asthe eX- perienceand the judgment of the manufacturer may dictate or various uses demand.

Having thus described this invention, what tinuous spiral passage,- the outer periphery of the passage being contiguous with the said tube; a follower slidable in the spiral passage to urge the cartridges toward the open end of the magazine, means outside of the housing to urge the follower toward said open end of the magazine;

and means of connection between the follower and said urging means being slidably extended through a wall of said housing. y

2. In a magazine the combination with an elongated tube adapted to receive a stac k of cartridges in the usual manner, a housing on an end of the tube, having a spiral passage therein contiguous with said tube andalso being adaptedto slidablyreceive'astack of cartridges; a follower in' the innerend of'the spiral passage movable outwardly through the passage'to urge the cartridges outwardly of the magaz'ine; 'an element extended from' the follower through the wall of the housing; "guides to guide the said element on a spiral path; and resiliently wound means engaging" the said element to move the same in the spiral guide; thereby to advance the follower in said spiralpassage toward and into saidtube; l 3. Ina magazine, a housing with a spiral passage therein; 'an'elongated open ended tube ex tended from the liousing-contiguously' with the outer end of thespiral passage so that said passage a'nd'tube is adapted to hold a continuous stack of cartridges; a follower'in the inner end of "the spiral passage movable, outwardly to urge thejstack through theirpassagefl and tube;'said housing having spiral slots'pn' the sides' thereof alongside the spiral passagefguide elements ex} ments to move the latter in'said slots as the last means are rotated; and resilient means to urge the rotatable means to rotate so as to move the elements outwardly in the spiral slots.

4. In a magazine ahousing with a spiral passage therein, an elongated open ended tube extended from the housing continuously with the outerend of the spiral passage so that said passage and tube is adapted to hold a continuous stack of cartridges; a follower in the inner end of the spiral passage movable outwardly to urge the stack through the passage and tube; said housing having spiral slots on the sides thereof alongside the spiral passage, guide elements extended fromrthe follower being slidable in said slots; rotatable means engaging the guide ele- -ments-to move the latter in said slots as the last means are rotated; and a resilient winding element connected to said rotatable means to rotate the latter as the winding element unwinds sojas to move the guide elements and the follower outwardly of said spiral passage.

V 5. In a magazine ahousing with a spiral pas-- sage-therein, an elongatedopen ended tube extended from the 'housing continuously with the outer end of the spiral passage so that said pas sage and tube is-adapted to hold a continuous slotsf rotatable means engaging' the 'guideelements to movelthelatter insaid slots as the last means are rotated; and a resilient "winding element connected to' said rotatable means to rotate the latter as the Winding element unwinds so as to move the guide elements and the follower outwardly of said; spiral passage; the; open end of thetube being partly closed and so formed as I V 7 7 p ,to coact with the repeating mechanism of a firetended 'from"the follower being slidablein said slots; rotatable -means engaging theguide' eleam. .a c 1 'ALONZO F. .GAIDOS.
