WATER PISTOL Filed Jan. 27, 1953 35 INVENTOR. 33 VALENTINE C V/NZZWZ BY 31 M A TTORNEY United States Patent WATER PISTOL Valentine C. Vincent, Yonkers, N. Y., assignor to Palmer Plastics, Inc., Brooklyn, N. Y.

" Application January 27, 1953, Serial No. 333,470

2 Claims. (Cl. 222- 79 This invention relates to a new and improved toy wateras a water container, and others which have a small pumplike mechanism with intake and discharge valves, mostly 7 built as ball-valves.

The object of this invention is to provide for a waterpistol comprising a new and improved squirting mechanism which consists of a minimum of individual parts and has no loose valve parts. The advantages are obvious. Together with a better operation the construction becomes stronger and easier to manufacture, while the whole body of the pistol serves as water container.

The invention will be hereinafter closely described and illustrated by the attached drawing. It is understood that this description and illustration serves merely as a sample and as one form of the various possible embodiments and methods of the idea of the invention within the scope of the attached claims.

In the drawings:

Fig. l is a side elevational view of the water-pistol including an embodiment of the invention.

Fig. 2 is a top plan view thereof.

Fig. 3 is a front elevational view thereof.

Fig. 4 is a side elevational view of the one-half part of the toys body, as viewed from the inside, and showing the arrangement of the squirting mechanism.

Fig. 5 is an enlarged longitudinal cross section of the valve and pump assembly of the squirting mechanism.

Figs. 6, 7, 8, and 9 show details of the valve mechanism.

The toy comprises two halves 11 and 12 shaped like a pistol, which contain the squirting mechanism and serve at the same time as the water container, when cemented together. A plug 13 fixed to a flexible strap 14 is connected to one of the two sheels to close the fill-in aperture 15. The squirting mechanism comprises a compact pump-like assembly embodying a T-shaped valve housing 16, a cylinder 17 with a return stroke spring 18, a piston 19, a piston rod 20 which serves at the same time as the trigger of the pistol with a flat top plate 21 which has a small cutout 22 running like a keyway in a key-shaped fln 23 to prevent the piston from rotating, said top plate at the same time preventing the piston rod from falling out due to a stopping knob 24 at the end of the key-shaped fin 23. The whole mechanism to which the suction pipe 25, and the discharge pipe 26 with the nozzle 27 are cemented, is retained within the body half 11 between its back wall, two protruding pins 28 and a collar 29 at the end of the discharge line which also holds said discharge pipe 26 in its place. In the base part 16 are two bores 30 and 31 for the suction and discharge lines respectively. A small hole 32 is arranged perpendicularly to the bore 31 and leads to a flapper check valve disc 33 which is kept in its place by a small retainer 34 which serves also with its boss 35 as the lower guide for the spring 13; Dia- 2,707,579 Patented May 3, 1955 metrically opposite port 32 is another port 36. Underneath the flapper check valve disc 33, the valve housing 16 is provided with a further receptacle hole 37 in which is seated a small valve spring 38. The valve housing 16 has on one side of its upper inside wall a protruding key 39 which fits into a notch 40 in the flapper check valve disc 33 and a notch 41 in the retainer 34 thus locating precisely these two important parts. The retainer 34 has a hole 42 leading when assembled from the interior of the cylinder 17 to the flexible portion 43 of the flapper check valve disc 33, and a proper cutout 44 which fits over the flexible portion 45 of the flapper check valve disc 33.

This simple and ingenious mechanism operates as follows: At the beginning the cylinder 17 is filled with water by pressing on piston rod or plunger 20 to exhaust the air from the cylinder and allowing the plunger to be projected by spring 18, at which time piston 19 and piston rod 20 are in their outermost position. When the trigger or piston rod 23 is manually pressed in, the water in the cylinder 17 is forced through the hole 42 of the retainer on top of the portion 43 of the flexible flapper check valve disc 33, which portion is supported by the small spring 38. The flexible portion 43 and the spring 38 are then deflected within the area or the wider hole 36, and the water is squirted out or expelled through the discharge line 26 and nozzle 27, thus creating the intended efiect. When the manual pressure is relaxed, the spring 18 projects the plunger producing a negative pressure in the cylinder 17 thus closing the valve 43 over port 36 and opening the valve 45 over port 32. The water pressure closes firmly the portion 45 of the flexible flapper check valve disc 33 against its seat in the valve housing 16 and over the intake port 32.

The small spring 38 is strong enough to help the flexible portion 43 to seal against the retainer 34, and the discharge port in it, while the cutout 44 in the retainer 34 allows the flexible portion 45 of the flapper check valve disc 33 to deflect upwardly and thus to open the intake port 32 to allow water from the container to enter through the suction pipe 25 into the cylinder 17. Then the procedure can be repeated again, and as often as water is in the containing body of the pistol,

What I claim is:

1. A toy water-pistol comprising a hollow pistol-shaped body serving as a Water container, a pump-like, intermittently operated water-squirting device enclosed within said body, said device comprising a T-shaped valve housing, a pump cylinder secured to the leg of the T, a piston within said cylinder, a piston rod extending from the piston outwardly of the body to represent a trigger, an intake pipe connected to one arm of the T housing, a discharge pipe terminating in a nozzle and connected to the other arm of the T housing, two pins projecting inwardly from the wall of the body, the valve housing being confined between said pins and against the back wall of the pistol body, and a collar at the end of the discharge pipe disposed in a groove in the nozzle bore of the body, said valve housing having a bore in the end of each arm of the T for the intake and discharge lines respectively and having a port perpendicular to and communicating with each or" the respective bores, a shouldered seat in the leg of the T where it meets the pump cylinder, a retainer disc in said seat, said retainer disc having a raised boss, a return-stroke spring having one of its ends fitting over and embracing said hub,

1 the other end of said spring bearing against the piston; a

key protruding diametrically inwardly from the inner annular wall of the shouldered seat, a keyway in the edge of the retainer disc to cooperate with the key, said retainer disc also having a segmented recess therethrough to align with the intake port, a single valve disc of flexible sheet material disposed on said shouldered seat under the retainer disc, said valve-disc having a keyway notch to mate witlrtlie keyand two diametrically opposed flapper petals to overlie the intake and discharge ports respectively, and a coil spring recessed in said housing to yieldingly bear against the discharge flapper petal.
