States PEN TYPE TEAR GAS GUN Don C. Williams, Huntington Park, Calif. Application February 26, 1954, Serial No. 412,882 Claims. (Cl. 42-1) This invention relates to discharging devices for tear gas cartridges, bombs, and the like, and in particular a tubular casing having a handle with a button controlled tiring pin therein and with a cartridge retaining barrel removably -mounted on one end whereby the gun is adapted to be held in one hand and lired by drawing the button or trigger rearwardly with the thumb of the hand.

The purpose of this invention is to facilitate carrying tear gas bombs and to provide means whereby a tear gas cartridge may be carried in a pocket, such as a pocket for a fountain pen and wherein the device may readily be removed and tired.

With the conventional method of throwing tear gas bombs through doors, windows, and the like, it is diicult to carry the bombs and because of the inconvenience of carrying bombs of this type tear gas bombs are usually not available when desired. With this thought in mind this invention contemplates a tear gas gun having 4a tubular housing with button actuated ring instrumentalities therein and with a cartridge retaining barrel removably mounted on one end of the housing whereby the device may be carried like a fountain pen and may readily be removed and tired as desired.

The object of this invention is, therefore, to provide means for forming a tear gas gun whereby the gun may readily be carried in a pocket of a police oiicer or other person. v

Another object of the invention is to provide an improved tear gas gun that is adapted to be held and operated with one hand.

A further object of the invention is to provide an improved tear gas gun that is of a simple and economical construction. f

With these and other objects and advantages in view the invention embodies a tubular housing having a plug threaded in one end and a barrel threaded in the opposite end, a tubular trigger carrier slidably mounted in the housing and having a button extended through a slot in one side of the housing, a hammer slidably mounted in the trigger carrier, a tiring pin slidably mounted in the hammer, springs positioned to actuate the trigger carrier, hammer, and tiring pin, and a spring actuated sear providing a key for locking the hammer to the trigger.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure l is a plan view illustrating the improved pentyPe tear gas gun.

Figure 2 is a longitudinal section through the gun illustrating the positions of the parts with the tiring pin in position to re the cartridge.

Figure 3 is a longitudinal section through the gun, taken on line 3 3 of Fig. l with the parts shown in released positions after tiring and with part of the barrel and cartridge broken away.

Figure 4 is a cross section through the gun taken on line 4-4 of Fig. 3 showing the sear operating and mounting instrumentalites.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved tear gas gun of this invention includes a tubular housing 10 having a plug or base 11 threaded in one end, a barrel 12 threaded in the opposite end, a cylindrical trigger carrier 13 slidably mounted in the intermediate part of the housing, a hammer 14 having a cylindrical stem 15 positioned with the stem slidably mounted in the trigger carrier, a rod 16 slidably mounted in the hammer and having a ring pin 17 extended from the forward end, aY button 18 providing a trigger extended through a slot 19 in one side of the housing and connected to the trigger carrier 13 with a screw 20, a spring 21 for returning the firing pin, a spring 22 for actuating the trigger carrier, a spring 23 for actuating the hammer, and a spring 24 for urging a sear 25 into locking positions for retaining the hammer in the trigger carrier.

The housing 10 is formed with internal threads 26 in one end into which a section 27 of the base 11 is threaded and the opposite end is .also provided with internal threads 28 into which the end of the cartridge barrel 12 is threaded. The housing is also provided with a head or partition 29 having an opening 30 therethrough in which the tiring vpin 17 is positioned and the slot 19 in one side of the housing is formed with a ramp or inclined surface 31 at the inner end whereby upon moving the trigger 18 rearwardly an inclined surface 32 of a projection 33 of the sear rides upwardly on the surface 31 moving the Sear from the position shown in Fig.'3

to that shown in Fig. 2 whereby the hammer 14 is released from the trigger carrier. At this time the spring 23 drives the hammer forwardly with the hammer engaging a collar 34 at the intersection of the rod 16 with the tiring pin 17 whereby the tiring pin is driven into a head 35 of a cartridge as indicated by the numeral 36. The hammer 14 is provided with a recess 37 that is adapted to receive the collar 34 whereby the collar is engaged by the end `surface 38 at' the base of the recess.

The stem 15 of thehammer is provided with an annular recess 39 into which the sear is adapted to extend, as

shown in Fig. 3 and, also as shown in Fig. 3 the sear is slidably mounted in a slot 40 that is positioned to register with the recess 39.

The sear 25 is provided with a pin 41 that extends into an opening 42 in the trigger or button 18 and the spring 24, which is positioned around the stem 41 is positioned in an enlarged recess 43 in the lower part of the button.

The head 44 of the screw 20 is positioned in a recess 45 in the outer end of the button and the intermediate part of the screw extends through an opening 46 which is aligned with the recess 45. The inner end of the screw is threaded into an opening 47 in the trigger carrier 13 'whereby the button or trigger is substantially integral with the trigger carrier.

The end of the rod 16, opposite to the end on which the tiring pin is positioned, extends into an opening 48 in the base 11. The base 11 is also provided with a knurled surface 49 and a similar knurled surface 50 vis provided around the inner end of the barrel 12. A clip 51 may also be provided on the housing for retaining the gun in position in a pocket or the like.

With the parts assembled in this manner the device will be carried with the parts as shown in Fig. 3 wherein the tiring pin is freely resting against the end of the cartridge and, with the parts as shown, it will be understood that it will be impossible to accidently lire the cartridge as itis rst necessary to withdraw the tiring pin. However, when it is desired to lire the cartridge the button or trigger 18 is drawn rearwardly until the surface 32 of the sear rides upwardly on the surface 31 whereby the hammer is released and the spring 23 drives the hammer and tiring pin against the cartridge. The barrel 12 may then be removed and a new cartridge placed therein.

lt will be understood that modications, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.
