WATER GUN Filed Nov. 18, 1949 INVENTOR.

q Jada i'elzer Patented Mar. 18, 1952 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to liquid-spraying guns, such as are used as toys by children, and has for its object the provision of a toy gun of this character by means of which a stream of water may be sprayed for an appreciable distance by means of air pressure built up in a water-holding chamber or reservoir.

Another object of the invention is to provide, in a toy of this character, pump means which is conveniently operated to build up air pressure in a tank or reservoir to cause ejection of a stream of water when a trigger release is operated.

More particularly, the invention contemplates the provision of a gun of this character provided with a water tank to which a manually-operated air pump is connected, the pump being operated by movements of a portion of the body of the gun, the pump serving to build up air pressure inside of the water tank; the invention also including the employment of a suitable triggeroperated valve which, when opened, will cause a stream of water to be ejected out of an outlet pipe or tube having its outlet end located at the forward end or barrel of the gun.

These and other objects are attained by the invention, a more particular description of which will hereinafter appear and be set forth in the claims appended hereto.

In the accompanying drawing, wherein an illustrative embodiment of the invention is disformed; Fig. 2 is a side view of the gun, with one of the halves of-the body of the gun re-. moved to show the operating parts; Fig. 3 shows the trigger and valve mechanism of the device; Fig. 4 is a sectional view taken on the line 44 of Fig. 2; looking in the direction of the arrows, and Fig. 5 is a sectional view taken on the line 5-5 of Fig. 2, looking in the direction of the arrows.

Referring to the drawing, the body of the gun consists of two main parts, namely, the forward part I and the rear or stock 2. These parts may be composed of wood, plastic material or metal and need not necessarily follow the exact shape shown, but may be readily made in simulation of ahnost any known type of gun or rifle. These parts of the gun body may be split or divided longitudinally, the two halves being held together by screws 3 or similar fastening elements. The inner faces of the halves of the gun body parts are suitably recessed to accommodate the several operating parts of the gun, one of said parts consisting of an air pump having a barrel 5 within which .a piston 6 is reciprocated in the known manner of hand pumps. The piston 6 is attached to the piston rod 1 which has its end 8 connected to the cross-piece 9 of a pump-operating yoke I0 which has its opposite end ll anchored in the stock portion 2 of the gun body. This arrangement is such that when the two parts I and 2 of the body of the gun are manually moved apart, or to the position shown in Fig. -1, and then brought toward one another to the closed position of Fig. 2, reciprocation of the pump piston 6 will occur and air will be forced from the pump through an outlet pipe H and past the check valve [2 located therein and into the water tank or reservoir I3.

The water tank or reservoir 13 contains the water H or other liquid to be ejected or sprayed from the gun. The outlet pipe through which the water is ejected is shown at l5, the same having a lower portion located within the tank and having its lower end located near the bottom of the tank. This pipe passes upwardly and through the top wall l6 of the tank and enters into the part I of the body of the gun and then extends horizontally, as at 25, to the front end of the gun; Located in the pipe 15 is a valve l'l which is normally held in closed position by means of the spring l8. The valve I7 is provided with a head I9 which is located in the path of a valveop: erating pin 20, pivotally connected at 21 to the upper end of the trigger 22. v;

The trigger 22 is pivoted on a pivot pin 23, mounted in the stock portion 2 of the gun and the trigger is spring-pressed by the spring 24 to normally inoperative position, as shown in Fig. 3 so that its operating pin 20 is retained away from the head I9 of the valve ll, or at least does not apply sufiicient pressure thereon to cause opening of the valve. It will be obvious that when manual pressure is imposed upon the lower end portion of the trigger, the same will pivot on its pin 23 and the operating pin 20 will be forced forward against the head IQ of the valve [1, causing the valve to be moved to open position, whereupon the water l4, under the pressure of air previously pumped into the tank or reservoir l3, will be forced upwardly through the outlet pipe l5 and through the horizontal portion 25 thereof to be ejected in a stream out of the forward open end 26 of the part 25 of the outlet pipe. Said forward open end 26 of the outlet pipe is located at the front end of hte barrel portion 21 of the un.

In preparing the gun for operation, the tank or ward part I of the gun, the tank may be gripped in one hand, and the handpiece 3:] in the other, to move the parts I and 2 apart and together a number of times to build up air pressure in the tank l3. When the pump has been operated a few times in the manner described, the ejection of the water will take place out of the outletend 26 each time the trigger 22 is pressed, until the air pressure in the tank l3 decreases and renewed pumping is required. When a considerable amount of air pressure is built up in the tank 13, a stream of water will be ejected for a considerable distance, and since the tank may be arranged to contain a substantial quantity of the liquid, the gun may be repeatedly used until the liquid is depleted. It may then readily be refilled as previously described.

While I have shown the gun in a certain shape and form, it will be understood that this is merely for the purpose of illustration since the gun and its operating parts are capable of numerous changes. For example, the tank 13 may be shaped and sized to appear as a handle portion or as a fitting on the forward part of the gun; the body of the gun may be of a shape and style to resemble any well-known make of guns, and various other changes may be made without departing from the spirit of the invention as expressed in the claims appended hereto.

What I claim is:

1. A water gun comprising, a two-part gun body, one of said parts forming a barrel part and the other forming the stock, an air pump carried by the barrel part, a liquid-holding tank also carried by said barrel part, a conduit establishing communication between the pump and the tank whereby operation of the pump will force air under pressure into the tank, pumpoperating means carried by the stock part of the gun body and caused to operate the pump when one part of the body is moved in a direction away from the other part of the gun body, an outlet pipe leading out of the forward end of the gun body, a valve for controlling the flow of liquid from said tank to said pipe, and trigger means carried by the stock part of the gun body for opening said valve to cause a stream of liquid to be ejected out of the outlet tube.

2. A water gun comprising, a gun body having a forward part and a stock part. a. pump carried within the forward part, a yoke attached to the stock part and extending into and slidable within the forward part, the pump having a piston, the yoke being coupled thereto whereby separating movement of the forward and stock parts of the gun body causes movement of the piston within the pump, an outlet leading from the pump, a water tank to which said outlet is connected, a valve between said outlet and the tank, a spray tube having one end located in the tank and its other end leading out of the front end of the forward part of the gun body, a valve in said spray tube, and trigger means carried by the stock part for opening the last-mentioned valve.

3. A water gun comprising a gun body having a forward part and a stock part, a pump carried within the forward part, a yoke attached to the stock part and extendin into and slidable within the forward part, the pump having a piston, a rod extending from the piston, the yoke being coupled to the rod whereby separating movement of the forward and stock parts of the gun body causes movement of the piston within the pump, an outlet pipe leading from the pump, a water. tank to which said outlet pipe is connected, a valve between said outlet pipe and the tank, a spray tube having one end located within the tank and its other end leading out of the front end of the forward part of the body, a valve in said spray tube between its forward end and the tank, and a spring-pressed trigger carried by the stock part and manually operable to open the last-mentioned valve.
