AUTOMATIC PISTOL.

Specification of Letters Patent.

Patented Oct. 24, 1916.

Application filed July 1, 1916. Serial No. 107,060.

' tols; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has for its object to providean improved fire armincluding a novel cartridge holder or magazine supported in the pistol handle and having two chambers each adapted to receive a supply of cartridges, whereby the cartridge capacity of pistols of this type is practically doubled.

Another object is the provision of means for controlling the projection of the car-' tridges from the two cartridge chambers to the firing chambers. v

\Vith these and other objects in view, the invention consists in the novel construction. combination and arrangement of parts as Will be hereinafter specifically described, claimed and illustrated in the accompanying .drawings, in which:

Figure 1 represents a side elevation of the improved fire arm, Fig. 2 represents a bottom plan view thereof, Fig. 3 represents a longitudinal sectional view through the pistol, Fig. i represents a sectional view through the double Cartridge holder or magazine removed from the handle of the pistol, Fig. 5 represents a front elevation of the barrel of the pistol, Fig. 6 represents'a' longitudinal sectional view on the line P43 of Fig. 3, and Fig. represents a transverse sectional view on the line 7-7 of Fig. Referring to the drawings in detail, wherein similar reference numerals designate corresponding parts throughoutthe several views, the numeral 10 indicates the body of the pistol, which includes the trigger guard, hollow handle 11 and integral upstanding block 12. A pivot pin 13 is insorted through the forward extremity of the body 10 and pivotally connects the forward portion'of the barrel 1i therewith, the rear terminal of the barrel being detachably connected with the upstanding block 12 by a detachable pin or bolt 15. The barrel H is formed with two longitudinal bores 16 and a spring-receiving opening 17 arranged centrally above and parallel to the bores 11'.

. The bolt of the pistol includes the breech block 18 slidablv mounted in the chamber 11) in the body 10 rearwardly of the barrclll and connected with a substantiallv U-shapcd guide member .30 slidably mounted upon the body 10.

The bolt 18 is nori'nallv retained in cngagcment with the rear terminal of the barrel 14. by the tension of an cxpansiblc spring 21 arranged in the chamber 17 and confined between a shoulder 22 and the head '13 of a rod 2l,'pivotall v conncctcd at 25 with the sliding bolt 15. A pivoted locking member :24 is mounted in a recess ffll'llltril in the bolt 18 and is adapted to cngagc in a rcccss formed in the rcarwardly extending portion of the barrel 14 to lock the bolt against operation. The locking mcmbcr 24 may bc conveniently operated by the user by means of a button 2 carried by the sliding guide :20 of the breech bolt in.

The bclt lb is providcd with two spaced firing pins 27 arranged in alimuiiciit with the bores 16 and normally relaincd in rearwardly extended positionlrv the tension of springs :2

The hammer mechanism comprises a pair of hammers 3U, pivotallv moun cd at ll in matically set in thc usual manncr b v thc rccoil movcmcnt of the bolt l Each hammer 30 is connected by a link 3; with one of a pair of rods 33. slidahlv mountcd in a chamber 'i-i formed in thc lowcr portion of the handle ll. hcn rclcascd. lhc lininmcrs 30 are automatically thrown forwardly against the rear terminals of the liring pins 27 by the tension of springs conlim-d in the chambers 34 bctwccn thc heads :in of lllc rods 33 and shoulders 37 formed intcrnullv of the chambers -H. The lowcrterminals of the chambers -H are normallv closed bv removable plugs 38. I

The upper edge portions of'thc hammers 30 are concavcd, as indicated at 3 and adapted to engage a shaft or bolt 40. non

rotatablv and slidablv mounted in the rear therethrough. liy the provision of the shaft 40 with a singlerecess 41 therein, one of the -hammers 30 is always held in inoperative position. However, either one of the hammers may be released, for operation, by so adjusting the shaft 40 as to swing rear.

4 wardly and downwardly through the recess 41.

The sprin actuated trigger 43 is connected with the ody 10 and is adapted to actuate the sear 44 mounted in the handle 11 and normally retained in engagement with the rod 33 'by;the tension of a leaf spring 45 confined inv the handle 11. Thc'tooth ofthe sear-44=is adapted to engage ina recess, 46

for the rod 33 to 100k the latter in elevated position against action of the spring The trigger 43 maybe locked against operation by atrigger safety lock 47 mounted injthef body 10- rearwardly of the triggerv 43.

-The magazincyor"cartridge holder, illustrated in detail in Fig. 4 comprises a body 48 having two cartridge-receiving chambers 49 therein in which is received asupplyof cartridges 50, which arenormally pressed tridges in either chamber V which is locked by t-hesear44.- The stop-T plate at the left side of the pistolis ad-" justed so asto prevent the projection of the upwardly withinthe holder 48 by thc'ten- 'sion of springs Z 1.- The holder 48 is adapt ed for insertion in the hollow handle 11, in the usual mannery and is locked in position in the handle by a catch 52*. The projection of-the cartridges 50 from either chamber of the holder 48 to the corresponding bore 16 of the double barrel is controlled by stop plates 50, slidably mounted in slots 51 formed in the opposite sides of the body 10 and coin nectedwith buttons 52, arranged"exteriorly of the body whereby the plates'oO may be conveniently operated to permit the carproper bore 16.

In use, the shaft 40 is adjusted so as t0 release the right hand'hammer 30 and the cartridge holder 48 having a supply ofcartridges 50 in each chamber 49 is inserted in the handle 11' The breech bolt 18 and guide member 20 are subsequently moved rearwa-rdly, thereby setting the hammer 30 cartridges contained therein" into the left hand bore 16 and thus by actuatingthetrigger 43 the. cartridges in the right hand chamber of thecartridge cessively fired. I

IVhen the supply of cartridgesi'n the right hand chamber of the holder 48 is ekhausted, the shaft 40 is-moved to'the left} subsequent to move the breech bolt- 18andguide member 20 rearwardly, thus permitting the leftiholder are su'chand hammer 30 to move freely througl iithe" recess 41- and lock the right hammer 3 0 in inoperative-position= The left hand StQP plate 50 :is subsequently adjusted s6 asto' permit the, pro ection of the' cartridges into the left hand bore 6 of the barrel.
