PETER VON` FRANTZIUS, OF CHICAGO, ILLINOIS PISTOL Original No. 1,760,674, dated May 27, 1930, Serial No. 305,730, led September 13, 1928. Application `for reissue led .Tuly 12, 1930. lSerial No. 467.592.

The invention relates generally to'pistols. More particularly the invention relates to that type of pistol which is in theform of a fountain pen and operates to discharge an incapacitating Huid, such as tear gas.'

One object of the invention is to provide a pistol of this type Which is generally of new and impro ved construction, may be manufac tured at a comparatively lovsT cost and is eX cecdingly eiiicient in operation.

Another object of the invention is to provide a gas discharging pistol in which provision is made for preventing the pistol from being used for tiring cartridges containing bullets or Jrojei'tilcs.

Other objects of the invention and the various advantages and characteristics of the present pistol construction Will be apparent from a consideration of the following detailed description.

The invention consists in the several novel features hereinafter set forth and more particularly dened by the claims at the conclusion hereof.

In the drawing which accompanies and forms a part of this specification or disclosure and in Which like numerals of reference-denote corresponding parts throughout the several views: Fig. 1 is a side elevation of a pistol embodying the invention. Fig. 2 is a longitudinal section. Fig. 3 is a transverse section taken on line 3-3 of Fig. 2. Fig. 4 I is a transverse section taken on line 4-4 of Fig. 2. ,Fig 5 is a perspective of the clip fo,r holding the pistol in a pocket.

The invention is eXemplied in a pistol comprising a cylindrical stoclr7 in which is slidably mounted a plunger 8. The outer end of this stock is provided With an internal the screw-thread 9 on the stock 7, and is screw-thread 9 to which a breech block 10 isr adapted to receive a cartridge 15 containing material which, when tired, will produce and discharge an invapacitating fluid, such as tear gas. The inner end of the barrel engages the rim of the cartridge. and is adapted to be screwed into position to hold securely the cartridge against the breech block. To load the pistol, the barrel 14 is first removed from the stock and the cartridge is inserted into the barrel. The barrel, with the cartridge therein, is then screwed into the stock until i the rim of the cartridge is confined between the barrel and the breech block. Thevplunger 8 is elongated so it Will slide freely in the stock 7, and is operatedto fire the cartridge by a coil spring 16, one end of Which-is held against lateral displacement in a socket 17 in said plunger and the other' end of which is held in a socket`18 in a cap 19. The cap has a substantially cylindrical portion or stem 2O Which extends into the stock 7 and is provided With an external thread 21 to tit an internal thread on the inner end of stock 7 to secure removably the cap in place. An advantage of utilizing a removable cap at the rear or inner end of the stock is that the spring may be readily removed for replacement or repair purposes. An additional advantage resides in the fact that access to the breech block may be had through the rear end of the stock after removal of the' plunger and spring. The outer peripheries of thecap and stock are flush. A clip for holdingthe pistol-ina vest pocket comprises a ring 22 which is clamped betvveena shoulder 23 on the cap 18 and the inner end of stock 7, and a resilient arm 2 4 which is provided at its outer end with a ball 25 to grip a portion of the pocket. To remove the spring 16 or the clip, it is only necessary to unscrevv the cap 18 from the stock 7. By clamping the ring of the clip in this manner, it may be rotatively shifted to bring the arm 24 into any desired position. A stud 26 is screw-threaded to the tiring plunger 8 and'extends through a longitudinally extending straight slot 27 in the stock. This slot permits the plunger and firing pin to be retracted against the force of spring 16. The stud has a head 28 so it 'abullet therein. For this purpose, a blade 30 of thin metal is confined in and extends ldiametrically across the barrel adjacent to the outer end of the shell of the cartridge. The material for/ producing gas is conned in the shell of the cartridge by a Wad 31,v

and the blade 30 is thin or has a sharp edge to server the Wad as it is projected from Vthe shell of the cartridge, so it Will be discharged from the barrel when the cartridge is fireds The blade 3() is provided with reversely extending arcuate portions 33 which fitiin an annular groove 35 in the barrel.

The blade and arcuate portions are formed of resilient metal so said portions can be sprung into the groove in placing` the blade .into the barrel. This exemplifies means for preventing the insertion of a cartridge with a bullet,`and for cutting the wad of the tear gas cartridge When it `is fired.

The bore of the barrel isfiared outwardly, as at 36, so as to cause the gas to spread in `a. ilaredcolumn. In practice, it has been f found that by spreading the column of gas,

it is more effective in reaching its intended mark than when it is projected from a truly cylindrical barrel.

The gas discharging pistol herein disclosed may be manufactured at a compara* tively low costby virtue i, of the fact that it consist-s of but a small number of parts. In view of thefact that the blade 30 is lo-v cated so as to prevent the use of cartridges havingbullets or projectiles, the pistol. may be used withoutfdanger of inflicting permanent injury.

The invention is not to be understood as 1 restricted to the details set forth, since these may be modified within the scope of the appended claims, Without departing from the spirit and scope of the invention.
