March 21, 1933. E. H. INGALLS GAS GUN 2 Sheets-Sheet 1 Filed Jan. 19, 1932 Inventor Patented Mar. 21, 1933 ELWIN H. INGALLS, OF AROIVLA PABIQILLINOIS GAS Gun Application filed January 19, 1932. Serial No. 587,590.

This invention relates to agas gun, the.

general object of the invention being to provide means for exploding a cartridge containing tear gas or the like, which can be operated by electric meansfor use in protecting banks and the like from robbers and for other purposes.

This invention also consists in certain other features of construction and in the combina- 1 tion and arrangement of the several parts to Fig. 4 is a section on line 44 of Fig. 1.' d

Fig. 5 is a fragmentary view of the upper member showing the plunger cylinder and plunger in end view.

Fig. 6 is a view of the trigger bar. y In these drawings, the letters A andB indicate a pair of members hingedly connected together at one edge as shownat 1 and having flanges 2 at their opposite edges which overlap when the two members are placed together. A cylinder or barrel 3 is carried by the member B with its upper end threaded in a hole in said member and held in place by a nut 4. This barrel or cylinder is adapted.

to receive a cartridge 5 which contains tear gas or the like which is released when the cartridge is exploded. A cylinder or barrel 6 is carried by the member A and the two cyl- 0 inders are in alinement with each other when the members A'and B arev in closed position as shown in Fig. 4, butwhen the members are separated as shown in Fig. 2, a cartridge can be removed or replaced on the cylinder 3.

V A plunger is carried bythe cylinder 6 and consists of apiston 7 having a small projection 8 for engaging the cartridge to explode' the same, and a stem 9 isattached to the pis-v ton and passes through the hole in the upper 0 or outer end of the cylinder and has a handle part lO thereon for enabling the piston to be raised, the pistonbeing forced downwardly to cause the projection'8'to explode the'car tridge through means of a spring 11, located in the upper part of the cylinder 6J Brackets 12' are carried by the member"A and slidably support a trigger rod "13which has aprojection 14: on its inner end whichpasses through afhole 15. in thecylinder 6 and acts to hold the piston 7 in raisedposition when the trigger rod is moved inwardly as shown in Fig. 4'. This rod is normally moved outwardly through the axis ofthe spring 16 thereon, and'said trigger rod is held inwardly against the action of the spring 16 j With its projection 14 under theipiston L7'by means of 'alatch 17 having one. end fastened to one of the brackets, and itsyotherv end adgpted'to'engageanotch 18 in the-trigger p, ro... m This latchjis tov be. adapted to be moved to releasingposition by the magnets 19 carried by the member'A as shown in Fig.1. Thus when the circuit to the magnets is closed, the latch 17 will be retracted in turn releases the piston! so that the spring 11 can move the pistondownwardly and thus cause the-projection 8to engage the cartridge and'explo'de the same. v The members A and B are then moved apart, the exploded cartridge taken from the barrel or cylinder 3 and a new one inserted, and the plunger moved upwardly and the'trigger rod moved inward ly to place its projection 14 in engagement with the piston 7 to hold the plunger in raised 1 position, the triggerrodbeing held in operative position by the latch 17. j

The parts are thenclosed andthe device is ready for another operation. As. before stated, the device can be used as protective means for banks and the like'or wherever desired and a number of these devices can be placed in I convenient positions with the switches of the circuits placed where they can: be readily operated by attendantsin the bank or other places so that the cartridges can be fired when the bank is held up. The de vices can beoperated one or more, or" as desired.

so thatthe 75 spring=16 can retract'thetriggerbar 13' which It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may 5 be made in the construction and in the combination and arrangement of the several parts provided that such changes fall Within the scope of the appended claims.

Having thus described my invention, what I claim as new is l. A device of the class described comprising a barrel containing a gas shell, a spring actuated plunger in the barrel for exploding the shell, a spring actuated trigger member for holding the plunger in inoperative position, a latch for holding the trigger member in operative position, magnetic means for moving the latch to releasing position.

2. A device of the class described comprising a pair of members hingedly connected together, a barrel carried by each member, one

of said barrels being adapted to receive a cartridge, a plunger in the other barrel, a springpressed' trigger rod for holding the plunger in inoperative position, a latch member for holding the trigger in operative position, and magnetic means for moving the latch to releasing position.

3. A device of the class described compris' ing a pair of supporting members hingedly connected together, a barrel carried by one 'member and adapted to receive a cartridge,

a second barrel carried by the other member, a plunger in the secondbarrel for supporting the cartridge When the two members are placed together with the barrels in alinement, a trigger rod for holding the plunger in operative position, supporting means on the second member for slidably supporting the rod,

40: and a latch for holding the trigger rod in operative position and spring means for moving the trigger rod to released position when the latch member moves to releasing position.

In testimony whereof I ailix my signature.

ELWIN H. INGALLS.
