DECEASED, LATE DETROIT, Vl\vIIC1I]G-A1\T, BY SELMA GRILL MTCHGAN, ASSEGNOR T0 ADL-METAL PRODUCTS C0., OF WYANDOTTE, lHIC-IIGAN, A CORPORATION OF DELAWARE f LIQUID GUN OR ESTOL Application filed June 28, 1928. Serial No. 286,844.

This invention relates to a liquid gun or pistol, and it has to do especially with a pistol in the nature of a toy for childrens use.

The invention contemplates such a pistol which involves certain novelties oi construction as to its general structure, and also a novelmechanism for effecting a plurality ot shots or discharges of liquid from a single load or charge of liquid. It is appreciated that such liquid pistols are not broadly new, and that it is not broadly new to provide a pistol wherein a plurality of sho-ts can be had. However, such a pistol which is to be used as a toy must be a simple well designed structure so that it can be manufactured at a minimum cost, and at the same time the structure must be rugged to withstand rough usage which it receives in use.

The invention aims to provide a pistol which meets these requirements. The structure as a whole is simple and composed of a minimum number of parts and easily assembled so that the cost of production is not great, and at the same time it is rugged so that it will not get out of order during use. The mechanism for effecting a plurality of shots is also simple, rugged and composed of a minimum number of parts.

In the accompanying drawings:

Fig. 1 is a side view of a pistol constructed in accordance with the invention with some of the outer casing being cut away to expose the inner construction.

Fig. 2 is a section on line 2 2 of Fig. 1 illustrating some of the details of the construction.

Fig. 3 is a section on line 3-3 of Fig. 1.

A frame for the pistol is composed of a pair of complementary halves 1 and 2 each having a half barrel formation 3 and 4. These complementary halves of the frame are preferably stamped from sheet metal.

One of the halves is provided with tongues 5,

and the other with notched extensions 6. When the two halves are placed together the tongues 5 are bent into the notch in the extensions and then the ends of the tongues are bent so as to overlap the extensions as at 7a' This holds the tw'c pistol halves together to form the complete pistol shell. It will also be noted that the tongues 5 and the notched extension 6 on top of the barrel portion of the gun serve as sights.

A magazine barrel 10 is disposed between the two barrel shaped parts of the complementary halves. One of the outside shell par-ts is provided with an opening 11 and the barrel is provided with a struck-out lip or projection 12. When the two halves are fixed together in the manner above speciiied the barrel is clamped between them and it is'retained from longitudinal movement by the projection 12 fitting in the opening 11. The torward end of the barrel is closed except for a small opening 13 which serves as a discharge opening and also for relilling the barrel.

Within the barrel is a piston 15 carried by a suitable piston rod 16. This piston may be formed of suitablematerial such as leather or the like which is disposed between the metal disks 17 held on the rod by punched out portions 18 of the rod. The opposite end of the rod is turned upwardly to provide a suitable loop formation 19 which extends outside of the pistol frame, the two halves of the pistol frame, each being cut away as at 20 to provide an elongated slot or opening to permit reciprocation of the piston rod. The piston rod is provided with a ratchet formation having a number of teeth 2l.

For the purpose of operating the piston, a trigger 25 is provided. This trigger may be advantageously formed ot' a single piece of sheet metal bent upon itself with the bight portion indicated at 26 being exposed and serving for contact with the finger of the operator. The two parts of the trigger are each provided with an aperture 27, and the metal of each complementary half of the frame structure is punched in as at 28 to form a fulcrum for the trigger.

A pawl is provided for operatively associating the trigger and the ratcheted piston rod. The pawl is shown at 30 and consists of a single stri of sheet metal bent upon itself, as at 31. he two parts ,of the pawl are each apertured as at 32. The pawl fits betweenthe two parallel sidee'e'. the trigger' which are formed by reason of the trigger being formed of a single sheet of metal bent in upon itself. The metal of the trigger is punched in, as at 33, so as to form projections which fit into the apertures 32 of the pawl. Thus the pawl is pivoted to the trigger.

The pawl and trigger are both under a restraining spring action and for this purpose a single spring is provided. This spring is shown at 34e and is connected to the pawl at one end, as at 35, by means of a suitable aperture in the pawl and connected to the frame of the pistol, as at 36. The part 3G is in the nature of a hook punched out of the metal of one of the complementary halves of the pistol frame. At least one end of the pawl is shaped as at 37 to function after the manner of a cam, acting upon a fixed part 38. This part 38 is provided bv the stamping out of part of the metal of one of the comple mentary frame sections of the pistol.

In 1 the parts are shown with the barrel filled with liquid and ready for the discharge action. To discharge a portion of the contents the trigger 26 is pulled by the finger of the operator so that the trigger fulcrums at 2S and advances the pawl, generally speaking, from right to left. rl`he pawl in the position shown in nig. 1 is in contact with the projection 38 so that its opposite end is out of Contact rith the piston rod. However, when thepawl is moved, it moves away from the projection 38 and the spring rocks the pawl on its pivot until its end moves up into contact with the ratcheted rod. Continued movement of the trigger causes an advancement of the piston a distance of one ratchet tooth.

The trigger is now released and the spring retracts the trigger and pawl. At the end of the movement the part 37 of the pawl strikes the projection 38 and is rocked on it pivot 3S so that its end 30 is moved away from the ratcheted piston rod. The position of the trigger and pawl, as shown lin the dotted `lines of Fig. 1, illustrates the position w b they assume when a shot has been disf A repetition of this operation effects successive separate discharges of the liquid in the barrel until the same is eX- hausted.

lVhen all liquid is discharged the piston will be at the forward end of the barrel and the loop 19 will be at the forward e-nd of the elongated slot 20. ln order to reload the gun, the end of the barrel is placed in a liquid and the piston retracted in the barrel back to the position shown in Fig. 1 by manually retracting the loop 19. ln this connection it is pointed out that whenever the trigger mechanism is released and allowed to come to rest, the pawl automatically ,disengages from the ratcheted piston rod. This permits refilling of the barrel at any time withoutl interference of the trigger and pawl mechanism.

rlhe structure of the pistol which involves two complementary frame halves, the manner in which they are connected together, the barrel, and means for associating it with the pistol frame, can be utilized wi h a different arrangement of trigger mechanism. For eX- ample, a sinvle shot mechanism can be provided. The number of discharges in a single load of liquid is variable without departing from the spirit of the invention by the expedient of changing only the number and position of the teeth of the ratchet formation of the piston rod, the relative movements of the trigger and pawl mechanism.
