I M. COHEN TOY PISTOL Filed April 5, 1943 n mm. LLZ' 72/ Patented May 22, 1945 UNITED STATES PATENT OFFICE TOY PISTOL Max Cohen, Rochester, N. Y. Application April 5, 1943, Serial No. 481,945

2 Claims.

plunger for ejecting the liquid may be actuated in successive steps.

Other objects and advantages of my invention willbe set forth in the claims and will be appa rent from the following description, when taken in connection with the drawing, in which:

Fig. 1 is a side elevational view partly in section showing the plunger in a retracted position;

Fig. 2 is a view similar to Fig.1 showing the plunger in a partly retracted position;

Fig. 3 is a View similar to Fig. 1 showing th plunger in its forward position;

Fig. 4 is a sectional view showing the sealing piston which is mounted on the plunger;

Fig. 5 is a front elevation of my novel toy liquid pistol.

As shown in the drawing, the novel liquid pistol of my invention comprises a barrel II which has a bore l2. The barrel is open on its rearward end, as indicated at H, and closed at its forward end I4 except for a minute aperture 16 through which the liquid is expelled or ejected.

Attached to the barrel is a hand grip H which may be secured to the barrel in any suitable manner, as by gluing or nailing, as indicated at l8. If desired, the barrel and hand grip may be made in one piece. Thehand grip has a bifurcated portion 19, as shown most clearly in Fig. 5, between the arms of which a trigger 2| is mounted and adapted to be actuated. The arms are provided with openings for the reception of a pivot pin 22 which extends through an opening formed in the trigger 2|.

The trigger is limited in its movement, as shown in Fig. l, by abutting against a wall 23 and by abutting at the other end of its movement against a wall 24. These two walls serve as stops to limit the movement of the trigger and a p1unger 26 which is actuated by the trigger in a manner to be presently described.

The plunger 26 is somewhat smaller in diameter than the diameter of the bore l2 and has mounted thereon at its forward end a piston 21 ment of the plunger.

the bore. The plunger is provided witlrapair of recesses or openings 23 and 29 which are adapted to receive projections or cam elements 3i and 32 formed on the upper end of the trigger.

The rearward end of the plunger is provided with a handpiece 34 while forward. of the hand piece 34 is a cam stop element 36 which is adapted to engage the margins of the opening I3 when the plunger is shifted forward or to the position shown in Fig. 2

All the parts thus far described, with the exception of the piston 2'! and the nails l8, if

nails are used, may be made of wood, plastic or other non-critical material. larly noted that no retracting spring for the plunger is employed. The parts of the pistol are simple and can be easily and inexpensively fabricated and assembled.

The projections 31 and 32 are so located on the trigger that they successively engage the margin of the openings 28 and 29. As shown in Fig. 1, the plunger has been manually retracted by pulling rearwardly on the hand piece 34. Retraction of the plunger shifts the trigger to the cooked position shown in Fig. 1. During the retraction of the piston the forward end of the barrel is inserted in a liquid so that the vacuum created behind the piston will draw water into the water chamber 38.

Upon actuation of the trigger, after the Water chamber has been filled with liquid, the cam element 3i first engages the margins of the opening 28 so as to shift the plunger forwardly and expel liquid from the water chamber through the minute aperture 16. The pressure thereof forces the liquid to a considerable distance in a fine stream. The cam stop 36 then engages the margins of the opening I3, as shown in Fig. 2, so that a stop is provided.

Upon further actuation of the trigger the cam stop 35, together with the plunger, is slightly depressed, so a to permit the cam stop 36 to enter the bore in the barrel. The trigger may then be further actuated to expel additional liquid from the water chamber and shift the parts to the position shown in Fig. 3.

It will be particularly noted, in shifting from the position shown in Fig. 2 to that shown in Fig. 3, that the forward cam projection 3| moves out of its aperture 28 and only the cam element 32 is effective to shift the plunger. When the plunger is retracted the rearward cam projection 32 is actuated so as to shift the trigger with the move- Later in the retractive movement the cam projection 3| enters the aper- It will be particuture and further retraction of the plunger actuates the trigger by engagement of the margins of the opening 28 with the cam projection 3|.

One of the particular features of my invention is that the pistol is capable of delivering two distinct shots of liquid since a pair of cam projections are adapted to cooperate with a pair of openings in the plunger and that these parts act successively to expel liquid from the water chamber. If desired, additional cam-projections could be provided on the trigger to engage a corresponding number of openings in the plunger so as to provide additional successive step movements of the plunger and thereby provide the pistol with a number of liquid shots.

While I have shown and described the preferred form of my invention it will be appreciated that various changes and modifications may be -'-made therein, particularly in the form and relation of parts, without departing from the spirit of my invention as set forth in the appended claims.

I claim:

1. A toy liquid pistol comprising, in combination, a handle, a barrel attached to the handle having a liquid dispensing opening, a plunger mounted in said barrel having at least a pair of indentations therein, a trigger pivoted to the handle and having at least a pair of projections adapted to extend into said indentations and successively engage the margins thereof, a cam stop mounted on the plunger for interrupting the forward movement of the plunger and a stop between said trigger and said handle for limiting the rearward movement of the plunger.

2. A toy liquid pistol comprising, in combination, a handle, a barrel attached to the handle having a. liquid dispensing opening 'at one end and a bore extending through the barrel from the other end to the liquid dispensing opening,

-a plunger mounted in said bore and having at least a pair of indentations therein, a trigger pivoted to the handle and having at least a pair of projections adapted to extend into said indentations and successively engage the margins thereof, 'anda cam stop mounted on said plunger, saidcam stop projecting from the plunger and being adapted to engage the barrel at the entrance end of the bore when'one of the projections has completed its actuationof the plunger so as to arrest the movement of the plunger and said cam stop 'being adapted to enter the bore when another of said'projections'actuates the plunger.

MAX COHEN.
