Patented' May 27, 1930 PETER VON FRANTZIUS, OF CHICAGO, ILLINOIS f PISTOL Application :tiled September 13, .1928.

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

One object of the invention is to provide a pistol of this type which is generally of new and improved construction, may be manufactured at a comparatively low cost and is exceedingly etcient in operation,

Another object of the invention is to pro- -vide a gas discharging pistol in which provision is made for preventing the pistol from being used for ring cartridges containing bullets or projectiles.

Other objects of the invention 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 defined by the claims at the conclusion hereof.'

In the drawing: Fig. 1 is a side elevation of a pistol embodying the invention; Fig. 2 is a. longitudinal sectlon. Fig. 3 is a section taken onl line 3--3 of Fig. 2. Fig. 4 is a section taken on line 4--4 of Fig 2. Fig. 5 is a perspective of the clip for holding the pistol in a pocket.

The invention is exemplified in a pistol comprising a cylindrical stock 7 in which is slidably mounted aplunger 8. The outer end of this stock is provided with an internal screw-thread 9 to which a breech block 10 is screw-threaded said block is preferably retained in a position inwardly of the outer end of the stock, and has recesses 11 thereinl t0 receive a key whereby it may be turned into and out of its operative position in the stock. In addition to the recesses, the block has a central opening 12 through which a` firing pin 13 on plunger 8 is adapted to pass. A barrel 14 has its inner end exteriorly threaded to lit the screw-thread 9 on the stock 7, and is adapted to receive a cartridge 15 containing material Which, when fired, will produce and discharge an incapacitating gas, such as tear gas. The inner end ofthe barrel engages the rim of the cartridge, and is 5 adapted to be screwed into position to holdunscrew the cap 18 from the stock 7.

securely Vthe cartridge against the breechI plug. To load the pistol, the barrel 14 is first removed from the stock and the cartridge is inserted into the barrel. Thel barrel, with the cartridge therein, is then screwed into the stock until the rim of the cartridge is conlined between the barrel and the breech plug. The plunger 8 is elongated so it will slide freely in the stock 7, and is operated to lire the cartridge by a coil spring 16, one end of which is held 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 20 which extends into the stock 7 and is provided With an external thread 21 to'fit an internal thread on the inner end of stock 7 to secure removably the cap in place. The outer peripheries of the cap and stock are flush. A clip for holding the pistol in a vest pocket comprises a ring 22 which is clamped between a shoulder 23 on the cap 18 and the inner end of stock 7, and a resilient arm 24 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 By clamping the ring of the clip in this manner, it- Inay be rotatively shifted to bring the arm 24 into any desired position. A stud 26 is screw-threaded to the firing plunger 8 and extends through a longitudinally extending straight slotf 27 in the stock. This slot permits the plunger and tiring pin to be retracted against the forcey of spring 16. The stud has a hea-d 28 so it can be readily engaged by a linger in retracting the plunger. To fire the cartridge, the user Will pull the head 28 ot' the stud'backwardly to retract the plunger vagainst the force of spring 16, and then release the plunger. Upon release of the plunger the spring Will impel the plunger outwardly with sufficient force to cause the firing pin 13 to lire the cartridge.

In a pistol for discharging cartridges for producing incapacitating gas, it is desirable to provide means to prevent the pistol from being loader:l with a cartridge having a bullet therein. For this purpose, a blade 30 of thin metal is confined in and extends diafor cutting the wad of but a small number of parts.

metrically across the barrel adjacent to the outer end of the shell of the cartridge. The material .for producing gas is confined inv the shell of the cartridge4 by a wad 431, and the blade-30 is thin or has a., sharp edge to 4sever the wad as it is projected from the shell of the cartridge, so it will be discharged from the barrel when thecartridge is fired. The blade `30 is provided with reversely extending varcuate portions 33 which fit in an annular groove 35 in the barrel. The blade and arcuate portions are formed of resllient metal so said portions can be sprung into the groove in placing the bladel into. the barrel. This exemplifies means for preventlng the insertion of a cartridgev with, a bullet, and the tear gas cartridge when it is fired.

The bore of the barrel is flared outwardly,

as at 36, so as to cause the vgas to spread in aA flared column. In practice, it has been found that by spreading the column of gas, it is more effective in reaching its intended mark thanvwhen it is projected from a truly cylindrical barrel.

The gas discharging pistol herein disclosed may be manufactured at a comparatively low cost by virtue of the fact that it consists of Inv view4 of the fact that the blade 30 is located so as to prevent the use of cartridges having bullets or I projectiles, the pistol may be used Without danger of inflicting permanent injury.

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

lI-Iaving thus described the invention, what I claim as new and desire to secure by Letters Patent, is

1. In a fountain pen shaped pistol of the character described, the combination of an elongated tubularv stock embodying an internal screw threadA at one end thereof, a cap adapted to close the said one end of the stock and 'provided with a substantially cylindrical part extending intothe stock, said part having formed therein an open-ended socket and embodying an external screw thread vfor engaging the aforementioned internal thread and connecting the cap removably in place,

one end ofthe stock, and a wad-cutting blade extending across the bore of the barrel and disposed so that it is in close proximity to the outer end of the cartridge shell and op# crates to prevent the insertion into the barrel of a cartridge with a bullet.

In a pistol, the combination of a cylin. drical stock, a spring-pressed firing element in the stock, a breech plug in the stock, a barrel for a cartridge, and I'a Wad cutter in the barrel -disposed adjacent the 'outer end of the 4. In a istol, the combination of a cylin- :drical stoc t, la spring-pressed firing element in the stock, a breech plug in the stock, a barrel for a cartridge, provided with a groove,

and a blade having a resilient strip heldinl said groove. Y

5. In a pistol, the combination of a cylindrical stock, a springzpressed firing element in the stock, a breech plug in the stock, a barrel Yfor a cartridge, provided with a groove,and a blade having a member extending across. the'barrel and resilient members confined in said groove.

'cartridge shell to preventv insertion of a cartridge with a bullet'.
