GAS GUN.

appnatmn mea November 7, l1924. serial No. 748,316.

The invention relatesin general to certain limprovements in a gun of general application designed to fire any kind of a projectile, and the 'invention specifically relates 5 to a gun preferably in pistol form and designed to discharge a gas or'volatile projectile by the firing of" cartridges contain ing gas producing substances. More definitely defined the invention relates to firing mechanism in a gun of the type described and Ato an improved form of l trig er control for such mechanism.

`T ev primary object of the invention is to provide a simple form of `gas gun which will beA ositive in its actuation, which can be casi y and cheaply constructed and which at the same time will feature a neat, well balanced for'mvof pistol simulating a conventional formof pocket revolver. The in- 0 lvention contemplates the providing of a fire arm which will accommodate-a plural-p ity of cartridges and which'will 'fire the cartridges from a fixed position successively by the manipulation of a single trigger mechanism which may be actuated repeated-l ly and until all the cartridges have been exploded.

Another object ofthe invention is to provide a type of gun, articularly applicable -when the gun is in tlie form of a plstol, in which the cartridge carrying clip Ais a readily replaceable umt with each cartridge pobarrels.

Various otherobjects and advantages of the invention will be in part obvious from an inspection of the accompanying drawings and in part will` be more fully set forth in the following particular description of one form of mechanism embodying my invention, and the invention also consists in certain new and novel features of construcfilooking at the leftlhand side of the4 except at the dlscharge end ofthe several" tion and combination of parts hereinafter set forth and claimed. In the accompanying drawings Figure 1 is a plan view looking down upi on a pistol illustrating a preferred embodi- Vment of the invention;

Figure 2 is a vertical sectional view taken on the medial line and on'the line 2-2 of Figure 1 showing the hammer in its normal inoperative position after it has fired the upper firing pin;

Figure 3 is a view in front end elevation shown in Figure 1.

Figures/4 and 5 are similar 'views of the firing mechanism, and in which Figure 4 is a view showing the hammer in retracted position just prior to being released; Figure 5 showing the .trigger in its final position, and the hammer released to its firing position;

Figure 6 is a horizontal sectional Yviewtaken through the upper portion of thegun and taken on the line 6-6 of Figure 3;

Figure 7 is a vertical sectional view taken on the line 7 7 of Figure 3;

Figure 8 is a horizontal sectional view taken on the line 8 8 of Figure 4; and

device Figure 9 is a detailedtransverse sectional .view taken on the line 9-9 of "Figure 4, in

each case looking in the direction indicated by the arrows.

In the following description and in the claims, parts will be identified by specic names for convenience of expression but they are intended to be as generic in their application to similar parts asthe art will permit.

In the drawings there is shown a hand pistol comprising a stock 10, provided with handle 11, finger trigger 12, trigger guard 13, all somewhat resembling a known form of hammerless revolver. 'The stock is hollow toprovid'e a closed compartment 14 for accommodating firing mechanism 15 actutrigger vmechanism includes the trigger proper 12. The forward position of the. stock forms. between the two outlining and upstanding walls 17 and 18 thereof, a barrel receiving recess opened at the top and at its forward end. The rear end of this recess is defined by an upstanding block 19 hereinafter referred to as a breech yated from a trigger mechanism which block which acts as a spacing block between the walls 17 and 18, delines the front end of the chamber 14, the rear end of the barrel clip recess, and is made resilient to provide some recoil cushioning eifect.

' lock the unit iii position. The unit is intended to include a plurality of barrels 23, three being shown in the drawings, but it is intended that the units shall contain the maximum number of barrels that can be carried conveniently, takin into consideration the character of cartri ge which each barrel is designed to carry and taking into consideration the convenient weight of the device as a whole.

In the device illustrated the barrels are designed to receive cartridges containing a gas forming substance. 'In order to prevent leakage, thepresent disclosure features a gas tight connection between the unit 2O and the stock so as to minimize any accidental leakage rearwardly from the gun.

Mounted in the breech block 19 is a plurality of firing pins 24, one for each of the barrels and each operatively disposed to fire the cartridge carried in its associated barrel. The pins are slightly longer than the breech block, extend transversely therethrough and are lspring f pressed rearwardly, each by means ofa spring 25 designed normally to project the rear end 26 of its associated pin 4 into the chamber 14 and in position to be engaged by a firing hammer 27 forming part of the firing mechanism. lAn renlargement 28 on each pin forms a bearing for one end of the spring 25 and limits the rearward lmovement of the pin under action of the spring.

The pins are selectively moved into their firing positions by means of thesingle firing hammer which is pivotally mounted at its lower end upon a rocking pin 29 for rocking movement in the lmedial plane of the piston. The hammer Ais formed of two main arts, a triangular shaped lower supporting ever 304 on the top flat side 31 of which is l.rotatably mounted a cylindrical barrel portion 32. lThe cylindrical portion is rotatably secured inits mounted position by means of an overhanging L-bracket 33 and which additionallyacts to provide an upper bearing '34 for the cylinder 32. The up- 'standing rear portion 35 of this bracket also provides an en aging post for a strong firing spring 36 t e upper end of which bears ragainst the hammer' and the lower end of which is removably secured to the stock at 37 as shown more particularly in igure 2. A supplemental firing spring, in this case shown' to be a coiled spring 38 is positioned between the fixed bracket part 33 and the stock at the upper portion of the hammer.

The cylindrical portion'32 of the hammer is provided with a plurality of pin receiving apertures 39 arranged in staggered relation considered both circumferentially and longitudinally of the barrel and designed so that when the hammeris in position to engage any one of the firing pins, then the apertures are so located that every other `firing in will project into one of .the apertures. he apertures are so disposed that upon each step of a step-by-step rotation of the hammer hereinafter described, the cartridges in the several barrels are fired consecutively until with either a complete or fractional rotation of the hammer all of the cartridges will have been fired.

The hammer portion 32 is rotated in its step-by-step movement by means of a pawl and ratchet form of progressive feed. The ratchet element is providedby means of a series of slots 40 formed in a reduced portion 41 of the lcylinder 32 to form a slip tooth construction, such as is shown in Fig'. 8. The teeth 42 so formed are disposed in the path of movement of a ratchet, in Fig. 2 shown to be a lever 43 with a ,nose end 44 for engaging the teeth of the ratchet and maintained in releasable positionby means of a pawl controlling sprin, r 45. It is understood from this construction that the movement of the hammer from the normal position in Fig. 4 into the retracted position shown in. Fig. 4 will cause the tooth which at the time is facing the nose 44 to move into engagement with the relatively fixed nose causing the same to react upon the cylinder 32 and to rotate the same one step in its rotary movement.

The hammer is moved from its normal positio'n shown in Fig. 2 into its retracted posi-` tion shown in Fig. 4 and tlie springs 36 and 38 put under tension by the engagement therewith of the trigger mechanism in its firing movement. 'lhis'trigger mechanism includes the finger piece.- pivotally mounted on the rear portion of which is a push lever 46 having a rear hammer engaging end 47 and normally raised in the elevated position shown in Fig. 2- by means of a spring 47. `The end 47 is caused to ride down a wedge shaped guide piece 48 formed on the underside of the breech block 19 and is moved by the action of the linger piece into engagement vwith a contact face 49 formed on the upper front side of the lever 30. As the trigger vmoves into its limiting position shown in Figure 4, the guide 48 acting on the push lever 46 pushes the same off the bearing face L9-and causes the end 47 to release itself from the trigger and to pass into the undercut release 50 delining the lower frontI side of the lever 30.4 Releasing the hammer from the holding effect of the .trigger mechanism permits spring 36 or firing pi-ns.

A suitable safety catch indicated at 5l is disposed to prevent retreat of the hammer and subsequent possibility of firing the device accidentally.

It is understood that thecbarrel unit may be replaced by a similar unit and the same pistol may be used repeatedly by inserting` another clip with fresh cartridges for the previously fired clip With its dead cartridges. It is also Within the scope of the disclosure to substitute for the clip illustrated other clips with different size and character of barrels so that with the unitary pistol cartridges of different sizes may be employed.

or different kinds of cartridges may be used, as Where 1t may be desired 1n the succesive operations of the trigger .to tire different -proj ectile.

forms of gases and eventually to fire a solid By means of the device disclosed any de'- sired sequence of projected material may be employed simply by selecting the proper charge clip to give the results desired. Any selectedcombination of projectiles may be. tired simply by the successiveoperation of the trigger. l p

While I have shown and described, and have pointed out in the annexed claims, certain novel features of my'invention, it. will be understood that various omissions. substitutions and changes in the form and details of the device illustrated and in its opera-` tion may be made by those skilled in the art without departing from the spirit of the invention.
