of the present invention is-i'n theform of a police clubl and isdesigied to fire a tear gas cartridge c. It comprises 'an elongated Stock (lliY illustrating in detail the manner in which istol is constructed so as The pistol whiclrfornis the subject matter 5 which has formed therein a longitudinally extending. bore 6 and is shaped toform a handle whereby the club-like pistol ma. wielded or pointed; The bore 6 is of'uni orm` diameterjthrouglioiitand extends from the' central or medial portion ofthe stock tothe inner end ofthe stock. An elongated cylinmouiited slidably in the bore '6 and is' provided at one end thereof with a firing pin 9. The inner end of the stock '5 is provided with in the open end of the bore 6 and embodies an enlarged socket 11.l A breech block y12 .fits in the ope en'd ofy the stock and is provided with an external screwthread which engages o o an internal'screw thread 10 the internal screw thread 10 and serves tohold thread 10 is prefera breech block, when screwed ,as aras p ossible into the bore, is retained m 'a'. position lace. lThe internal screwj bly of such len h that the Awherein the outer face thereof is lush' with the portion of the stock that deiines the inner end of the socket 11. The breech block 12 has a kerf or slot'13 in .the outer face thereof to receive a key or screw driver whereby it may be rotated into andou't of its operative posiembodies at the inner end thereof a stem 17.

The latter is formed integrally with the barrel and embodies an external screw thread 18 lwhich is adaptedto engage an internal screw thread 19in the portion of the stock that dei fines the side' Wall of the socket 11 so as to connect he barrel removably to .the stock.

The portion of the central opening 16 at the inner or stem-equipped end of the barrel 1s shaped to receive the tear gas cartridge 0.

. The end face of the stem 17 is adapted togengage .the rim of the cartridge and operates, when the barrel is screwed into its operatlve position, tov hold the cartridge against the breechblock 12, as illustrated in Fig. 2 ofthe drawings. To load the pistol, the barrel 15 is first disconnected from the stock 5 and then the gas cartridge c is .inserted into place. Thereafter the. barrel. with the cartridge therein is connected to the stock by screwing the stem 17 into the socket 11 until the rim of the cartridge is clamped between the breech block and the inner face of the stem.

The plunger 8 is constructed sothat it slides freely in-the bore 6 a-nd is operated to discharge the cartridge c by means of a coil spring 20. The latter is' confined in the closed g end portion of the bore 6 and bears against ythe plunger 8.l The plunger is retracted ,against the force of the spring 2() byv means of a stud 21. The latter comprises a shank l22, one end of which `extends transversely through and'is screw threaded to the central portion of the plunger. The other end of the shanlfprojects through a straight longitudiyso nally extending slot 23 in the stock andis provided with'a head 24. .The slot 23 operates to permit the plunger to be retracted against the force of the spring a suiicient distance to result in the firing of the cartridge when the plunger is released. .k

In order to prevent the .pistol from being discharged accidentally in the ,event that it shouldbe dropped or jarred,\`aslot 25 is formed in the lstock 5. This slot, as illustrated in Figs. 1 and 3, of the drawings, is adapted to receive the stud v21 and is arranged so`that one end thereof is connected vto and communicates with the cocking end of the straight longitudinally extending slot 23.

The other end of the slot 25 is positioned but a'small distance from the firing endof the slot and serves, when the stud is confined .or cocked position.

cartridge.-

tion, that is, in a position wherein the plunger is spaced from the breech block 12 so that the tiring pin 9 is out of contact or engagement with the percussion cap of the tear gas cartridge o. The s lot 25 is substantially straight, extends-at a. comparatively small angle with respect tothe slot 23 and is joined or connected to the cocking end of the slot 23 by a curved portion 25a. The latter makes it possible to insert 'the stud 21 into the slot-25 When the plunger 8 is retracted into its tiring i When it is desired to lock the plunger in its safe position, the stud 21, by manipulation of the head 24,-is shifted toward the outer end of the stock 25 so as to retract the plunger 8 again-st the force of the coil spring 20. lWhen the stud 21 reaches the cocking end of the slot-23, it is shifted laterally in tothe curved portion 25a of the slot 25 and is then released. Upon release of the stud, the coil spring 20'forces the plunger l 8 towards the cartridge until it is arrested as the result of the shank 22 of the stud coming `in contact with the closed endof the slot 25.

When it isdesired to releasethe plunger from its locked or safe position, the stud 21 is shifted toward the curved portion 25a of the sionjcap of the cartridge 0. The slot 25 exemplilies simple and improved means for releasably locking the plunger 8 in a position vwherein the firing pin 9 is spaced from the breech block 12 and is out of contact with'the To veliminate the possibility of a. cartridge with a bulletbeing fired from the pistol` the portion of\the opening 16 in the outer end of the barrel 15 is formed so thatoit is of less diameter than the cartridge-receiving portion. An annular shoulder 26 joins the portion of the opening of reduced orsmaller diameter than the cartridge-receiving portion. This shoulder serves asan abutment and opcrates as illustrated in Fig. 4 of the drawings, to arresta bullet or projectile of a. regular cartridge in the event that such a( cartridge is fired in the barrel. To prevent the bullet of a regular cartridge from being forced through the opening of smaller diameter, radially extending ducts 27 are formed in the inner end of the barrel. The. ducts extend from the cartridge-receivin;l` portion of the opening 16 to the outer face of the barrel and permit the. gas and products of combustion to escape so that they are dissipated. and do not tendy to force the bullet or 'projectile through the barrel. There arepreferably four ducts. `The latter are disp'osed midway between the annular shoulder 26 and the base part of the externally threaded stem 17. By so disposing or positioning' the ducts, the inner ends of the ducts are not coi-ered by the shell or casing' of a cartridge containing a bullet and hence are exposed so as tovpermit of the Iready egressor discharge of the gas and products of combustion du-ring. firing from the barrel of a .virtue of thefact that the shell or casing of the gas cartridge 0 is of greater length than the shellv or casing of a regular cartridge, the

ducts 17 are covered when a gas cartridge 1s used in the cartridge-reeivingportion of the opening 16 and arel hence closed against the discharge of gas therethrough.

The outer end of the stock -5 1s provided ywithV a reduced stem 28 an'd embodies a cy- -lindrical compartment- 29 for/a spare gas ,car-

tridge c. The compartment 29 extend-s through the stern 28 and into the interior of the stock 5 and is normally closed by a capY 30. The latter has formed therein a central socket 31 for the stem 28 andis secured removably to the stem by means of an internal screw thread 32. The latter-is adapted to engage an external screw thread on thestem 28.

To permit the pistol to be carried readily, a strap 33 is provided.` v This strap is formed of leather or any other suitable material and extends through an-e'ye 34 which iscarried by the cap 30. Theeye 34 embodies a stud 35 which extends throughvan opening in the central portion of the cap Aand is beaded or riveted over so' as to connect permanently the eye 34 to the cap and form a. rotatable or swivel connection whereby the, eye may be readily turned relatively to the pistol. "When the cap is in its closed or operative position, the beadedover or riveted porti' n o f the stud abuts. against thevrilny port \n of' the spare gascartridge cvand holds the cartridge against displacement in the compartinent 29, as illustrated in Fig. 2.

The cap 30 is rounded and is preferably of greater diameter than the outer endI of the stock 5 so that'it forms together with the contiguous portion of the stock, a wellde'fined handle for the pistol.r The portion of the stock adjacent the cap `embodies a series of annular grooves 36 which tend to prevent slippage of .theclub when rthe handle part of the pistol is held in the hand: The barrel l5 forms the head .of the club-shaped pistol.'

. The pistol may be carried by'gripping the y stock around the grooved portion or by holding the strap 33. When it is desired' to load the pistol, the barrel l5'is removed-from the stock and the gas cartridge is inserted into the cartridge-receiving portion of the opening 16, as previously pointed out. After insertion of the cartridge, the barrel is con- 'nected to the stock by rotatingjthe stem 17 into connectednrela-tion with the internalVv regular cartridge. By

screw thread in the socket 11. Firing of the y gas cartridge is effected by -shifting the stud' f 21 into the cooking end of the longltudinally extending slot 23 so as to retract the r8. When the stud is released, the spring 20 forces the plunger towardthe cartridge and eli'ects firing of the cartridge through the medium of the firing pin 9 andthe percussion cap ofthe cartridge. After firing the pistol, if it is desired to reload, the sparecartridge c is withdrawn from the compartment 29 by plunger remoiing-the cap 30 and inserting it into the4 socket-receiving portion of the opening 16 while the barrel and stock are in disconnected relation.` When it is desired to carry the pistgl with the gas .cartridge in the barrel, the

plunger is locked in its safe position by shifting the 'stud 21 into the slot 25.r The' latter, as hereinbefore described, cooperates with the stud so. as to hold releasably thep plunger 8 in a position wherein the firing pin .9 is spaced from the breech block 12.

The herein disclosed pistol may bemannfactured at a comparatively low Ycost -by virpended claims, without .departing from theY 4spirit and scope ofthe invention. v
