DAVID HEYMAN, OF NEW YORK, N. Y., ASSIGNOR T0 MOHAWK METAL TOY (10., INC., A CORPORATION OF NEW YORK.

LIQUID-PISTOL.

Application filed May 28, 1919.

To all whom it may concern:

Be it known that I, DAVID HEYMAN, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new and useful Improvements in Liquid-Pistols, of which the following is a specification.

My invention relates to an improved liquid pistol which may be operated to eject successive quantities from a body of liquid, thus providing what may be termed a repeating istol.

One 0 the characteristic features and objects of the present invention consists in the utilization of the barrel as the reservoir for receiving the liquid to be ejected. So far as I am aware, in the construction of liquid pistols, it has heretofore been customary to employ a separate cell as a liquid reservoir, but constructions of this kind entail certain manufacturing disadvantages which are obviated by my invention wherein the barrel itself forms the liquid receptacle.

Another feature and ob ect of the invention is the simplification of the mechanism for ejecting the liquid, thus reducing the number of parts and the cost of manufacture to a minimum.

Two forms of the invention are illustratively exemplified in the accompanying drawing, in which Figure 1 is a side elevational view partly in section of one form of the invention;

Fig. 2 is a sectional elevational view of a portion of the means for operating the pluner; g Fig. 3 is a perspective view of a rocking frame or yoke used in the actuation of the plunger;

Fig. 4 is a side elevational view partly in section of a modified form of the invention; and

Fig. 5 is a perspective view showing the manner in which the modified form of the invention is employed.

In both forms of the invention shown in the drawing the barrel itself forms the reservoir for the liquid, and the difl'erence between the two forms lies in the operating means for the plunger.

Referring to Figs. 1 to 3 of the drawing, 10 denotes the handle or stock which is preferably formed integrally with what may 'be termed the breech, these two parts Specification of Letters Patent.

being arranged substantially at right angles to each other. Held in the forward part of the breech 11 is a barrel 12 which constitutes the liquid reservoir. In the front wall of the barrel 12 is a small opening 13 which serves both for the admission of liquid to and the ejection of the same from the barrel 12.

Operable in the barrel 12 is a plunger 14 carried at the forward end of a plunger rod 15, the rear end of which is provided with a stud 16, projecting througha slot 17 in the upper face of the breech 11.

Carried loosely on the plunger rod 15 is a three sided frame comprising the front wall 18 and the side walls 19. Formed in the front wall 18 is an orifice 20 through which the plunger rod 15 passes. The frame is held in biased contact with the plunger rod, as clearly shown in Fig. 2, by means of springs 21 and 22, the former being attached at one end to a cross pin 23 which extends through slots 24 near the upper edges of the side walls 19, and the latter spring having one end engaging the hole 25 near the lower edge of the front wall 18. The rear ends of both springs 21 and 22 are secured to the studs 26 and 27, respectively, near the rear end of the breech 11, the stud 26 being positioned farther rearwardly than the stud 27.

Fulcrumed on the pin 28 extending through the body of the frame is a trigger 29 the upper portion of which is forked and the arms of which extend at opposite sides of the outer walls 19 of the frame and are orificed near the top so as to engage the pin 23.

The operation of this form of the device is substantially as follows: Assuming the barrel 12 to be filled with liquid, the ejection of the latter in successive quantities is effected by repeated pressure on the lower end of the trigger 29. The springs 21 and 22 normally hold the frame 18, 19 in the biased position shown in Figs. 1 and 2 in which the wall of the orifice 20 rather lightly engages the plunger rod 15. By pressing the trigger 29 the upper edge 20* and the lower edge sure the spring 21 which is under greater tension than the spring 22 tends to relieve the tight or positive engagement between the frame 18, 19 and the plunger rod and convert such positive engagement into a loose engagement. When the plunger 14 has reached the extreme forward position in the barrel 12 the liquid contained in the latter has been ejected and a fresh supply of liquid may be drawn into the barrel 12 by retracting the plunger 14 through the medium of the upstanding stud 16.

In the modified form of Figs. 4 and 5, 12 denotes the barrel, 10 the stock or handle, and 11 the breech. 29 is a trigger which in this form of the invention is a dummy merely. Movable in the barrel 12 is a plunger 14 having attached thereto the plunger rod 15. Formed in the side of the breech 11 is an elongated slot 17" through which projects a pin 16 extending from and substantially at right angles to the plunger rod 15. In the modified form of the invention the entire plunger operation is effected through the medium of the pin 16. The operation is shown in Fig. 5-. The pistol is grasped in the hand with the index nger restin on the trigger 29 and the thumb engaging the pin 16. By constantly or intermittently pressing the pin 16 forward the plunger rod 14 is forced forward in the barrel 12 and liquid is ejected through the front orifice 13. When all liquid has been ejected a fresh supply may be drawn in by simply moving the pin 16 rearwardly in the slot 17, thus retracting the plun er 14 and drawing liquid in through t e opening 13 by suction.

\Vhat I claim is 1. A liquid pistol comprising a barrel, a plunger reciprocable therein, a plunger rod connected to said plunger, a frame loosely engaging said plunger rod, means adapted to cause a positive engagement of said frame with said plunger rod and means to advance the frame.

2. A liquid pistol comprising a barrel, a plunger reciprocable therein, a plunger rod extending from said plunger, a frame through which said plunger rod passes, springs for holding said frame in biased contact with said plunger rod, and a trigger for moving said frame into positive engagement with said plunger rod and advancing said plunger rod.

In testimony whereof I have affixed my signature in presence of two witnesses.
