M. A GILL Filed Sept 29, 1953 INVENTOR Mer/e G/// BY Patented June 19236 UNITED STATES PATENT OFFICE FIBEARM Application September 29, 1933, Serial No. 691,466

5 Claims.

My invention relates to firearms and more particularly to a device of that character to be supported in the palm ot the hand and fired by closing of the ngers against a ring collar and has for its principal objects to provide a firearm of this type which is not liable to accidental discharge and that is automatically recocked after ring.

It is a further object of the invention to provide a rearm of this character for discharging tear gas shells.

In accomplishing these and other objects of the invention, I have provided improved details o! structure, the preferred form oi which is illustrated In the accompanying drawing. wherein:

Fig. 1 is a perspective view of a firearm embodying the ieatures o! my invention and showing the method of holding the device for tiring a shell.

Fig. 2 is a perspective view of the parts of the device shown in disassembled spaced relation to better illustrate their construction.

Fig. 3 is a longitudinal section through the device showing a shell in position with the device cocked and ready for tiring.

Fig. 4 is a similar view showing the firing pin in retracted position and about to be released by the automatic trip for tiring the shell.

Fig. 5 is a cross section on the line 5 5, Fig. 3.

Fig. 6 is a perspective view oi the tiring pin latch.

Referring more in detail to the drawing:

I designates a hand stock comprising a cylindrical body portion 2 provided with a substantially semi-spherical end l adapted to seat in the palm of the hand. I'he opposite end oi the stock is provided with a cylindrical bore 4 terminating in a reduced internally threaded socket 5 to mount a ring pin guide tube 6.

The firing pin tube i includes a sleeve having an externally threaded end I to engage in the threaded socket 5. The opposite end of the guide projects beyond the open end of the stock and is provided with internal threads l terminating in a stop shoulder 9 formed by the reduced bore I0 of the sleeve. The guide member is also provided substantially midway of its length with a rectangular slot II of sufficient length and width to accommodate the ring pin latch, as later described.

The ring pin is designated I2 and includes a 'cylindrical body portion I3 of suitable diameter to be snugly slidable in the bore I of the guide.

The rear end oi the pin I2 is provided with a spring socket I4 to receive one end oi' the ring pin spring I which has its other end housed within the guide and engaging against the bottom of the socket 5 to urge the pin toward flr- 5 ing position. The forward end of the pin is reduced in diameter to form a point I6 for rlng a shell I1.

The periphery of the body portion of the pin is also provided with an annular groove I8 forml0 ing a keeper or latch shoulder in which a latch I9 engages when the ring pin is cocked.

Threaded into the outer end of the ring pin guide tube and engaging against the shoulder 9 is a breech block having a cup shaped recess 15 2| at its rear end and a flat forward face or seat 22 against which the base 23 0i the shell abuts. The breech block is also provided with a central axial opening 24 to permit projection of the point oi the tiring pin therethrough. as shown in Fig. 3. 2O

The tiring barrel 25 of the device is of substantially the same outer diameter as the outer diameter of the tiring pin guide and its inner diameter is of suitable bore to accommodate the size oi shell II to be used therein. The breech 25 end 26 of the barrel is reduced in diameter and externally threaded as at 2'I to be mounted in the threads of the tiring tube and is of suilicient length so that when the end face 28 thereof engages the rim 29 of the shell the opposite side 30 oi the rim is clamped tightly against the dat face 22 of the breech block and the shoulder I0 formed by the reduced breech is tightly engaged with the end oi the firing pin tube.

In order to move the firing pin into retractive position, I provide a tiring collar 3l which is slidably mounted on the guide and has its rear end slidable within the bore 4 of the stock I, as now to be described. 40

The member 3i comprises a cylindrical sleeve 32 of slightly less diameter than the diameter of the bore 4 and has its ends provided with internally extending anges 33 and 34 to slidably bear upon the rear end of the barrel 25 and ring 45 pin guide tube 6 respectively and whereby the sleeve is spaced therefrom to form a housing for the spring latch I9. The ring collar is normally retained in projected position relatively to the stock by a coiled spring 35 sleeved over the guide 50 and having one end engaging the bottom of the bore 4 and its opposite end the ange 34.

The latch I9 is formed of at spring metal having a flat body portion 36 terminating in a rearwardly extending tongue 31 having a down- 55 wardly curved end 3B operable in the slot il and adapted to engage an inclined end 39 of the slot to eiect release of a firing pin, as later described. Formed integrally with the body portion of the latch at opposite sides of the tongue 31 are inwardly extending ears 40 and 4I adapted to engage in the groove I8 formed in the firing pin when the firing pin is in projected position.

The latch spring is retained in position within the tiring collar by fastening devices extending through an opening 42 in the collar and through an opening 43 in the spring and is retained in parallel relation with the axis of the guide tube by the ears 40 and 4i and the curved portion of the tongue which extend into the slot for engaging with the periphery of the ring pin.

In assembling a device constructed as described, the tiring pin guide tube 6 is screwed in the socket 5 of the hand stock. The ring pin spring I5 and the firing pin i2 are then sleeved within the tube guide. The breech block 20 is then threaded into the open end of the tube until it seats against the shoulder 9.

The cocking spring 35 and the ring collar are then sleeved over the guide tube so that the rear ends thereof enter within the open end of the hand stock, whereupon the ears 40 and 4| drop into the slotted opening Il in the tube and enter the annular recess in the firing pin. The ears then latch the firing collar against tension of the spring I5 since they engage with the end 44 oi' the slot Il opposite the inclined end $9, previously described.

A shell i1 is inserted into the breech of the barrel 25 so that the rim 29 thereof seats against the breech. 'Ihe barrel is then screwed into the end oi the ring pin guide tube until the base of the shell engages the breech block. The ring arm is then cocked. loaded and in condition for tiring.

To lire the shell, the device is held in the hand with the stock engaging the palm thereof and the barrel extending between the fingers. as shown in Fig. l.

The fingers are then drawn back against the tiring collar to move it retractively within the bore oi' the hand stock.

Since the ears 40 and 4| are seated in the groove IU in the ring pin. the firing pin will also be moved retractively against the tension oi' its spring I5 until the curved end 38 engages the inclined end 39 of the slot. Additional movement oi the sleeve then causes the tongue to be cammed upwardly against the tension of the latch spring to withdraw the ears 40 and 4i from the annular recess i8 o! the tiring pin so that the tiring pin is released and driven by the stored up tension of the tiring pin spring against the tiring center of the shell I1 to explode the shell.

Upon release of the iingers from the tiring collar the cocking spring 34 returns the collar to normal position and restores the ears 38 and 39 to engagement with the recess of the ring pin to again couple the collar therewith so that the device is in position for tiring upon retraction of the collar, as above described.

A new shell may then be inserted by removing the barrel, inserting the shell in the barrel and replacing the barrel in the end of the ring pin tube. as above described.

The rearm is then loaded and ready cocked so that when the device is to be used the shell may be iired simply by retracting the rng collar against tension o1' the spring.

It is thus apparent that since the device is automatically cocked after each ring operation, it is not neceary to cock the ring collar prior to retraction of the firing pin.

It is also apparent that due to resistance of the spring 34, the tiring collar cannot be accidentally moved to firing position.

While a firearm constructed and assembled as described is ladapted for use in firing various types oi shells, it is particularly adaptable for ring a tear gas or similar shell and there is no danger of accidentally discharging the gas when the firearm is carried in the pocket of the owner.

If the device is to be used for tiring tear gas shells only. it may be desirable to prevent its use for tiring a bullet, and in this instance, a pin 46 is inserted transversely of the bore of the barrel to preclude such use, otherwise the pin will be eliminated.

What I claim and desire to secure by Letters Patent is:
