Application November 5, 1956,;Serial No. 620,494
4 Claims. (-Cl.'222-78) .The present invention relates to a .toy liquid squirting device, .andmore particularly toawater gun in a body rough usageandeconomical'mass production. This calls for relatively few parts, easily fabricated of'tough, low
cost materials, preferably by mass productionmethods, and readily assembled with a minimum of labor.
Accordingly, it is an important object of the invention to provide a liquid squirting device of "rugged and economical construction. p
Another object is to provide a water gun simulating a camera designedfor rough usage and economical mass production. I
A further object is to provide a water ,gun simulating a camera made of a minimum number of parts, capable of inexpensive fabrication from .tough materials, .and
capable of ready assembly with the requirement of a minimum amount of labor.
Additional objects will become apparent from the following description.
Stated in general terms, the liquid or water squirting camera of the invention comprises the following. A barrel simulating a camera lens barrel, is provided with a pinhole through a wall in the front end thereof simulating a lens. A resilient thimble of a plastic or rubbery material is positioned in the front end of the barrel to form a liquid-tight chamber communicating with the atmosphere through the pinhole. The barrel is slidably or telescopically associated with an actuator member. The actuator member in turn is provided with a projection extending into the rear of the barrel to the thimble. As the actuator member is forced into the barrel, the projection forces the Wall of the thimble toward the front end of the barrel, and liquid is squeezed from the chamber in the barrel through the pinhole to the atmosphere.
For reasons of economy in fabrication and assembly of the parts of the invention we prefer to cast the barrel and camera body as a single unit, together with the front wall and any auxiliary, guide or slide means, of a synthetic plastics material. Similarly, we prefer to cast the actuator member, together with the projection and any auxiliary, guide, slide and chamber means, as a single unit of synthetic plastics material. The thimble preferably is dimensioned to fit tightly in the barrel without the use of cement.
A more detailed description of a specific embodiment of the invention is given with reference to the drawing wherein:

Figure 2 is a vertical sectional view taken on the line 2+-2 of Figure 1 showing the camera gun barrel fully extended relative to the actuator;

Figure 3 is a cross-sectional view taken ,on the line 33 of Figure 2 showing guide and slide means for the actuator and the barrel;
Figure 4 is a vertical sectional view similar .to that of Figure 2 but showing the actuator pushed into the barrel as faras it will go;
-Figure Sis a partial vertical sectional view taken on the .line '5-5 of Figurel showing structural features of. the
Figure 6 is a partial perspective view showing structural .details of the actuator.
,In the embodiment shown in the drawing, the barrel member 10 is .cast as a single unit consisting of hollow gun orsimulated camera lens barrel .11, end wall or simulatedlens 12in the end of the barrel, a pinhole 13 through the end wall 12, a guide slot 14 at the top rear of the barrel, and a simulated camera body 16. The barrel member 10 preferably is cast from a tough synthetic plastics or synthetic .resins material.
Similarly, the actuator member 17 is castas a single unit consisting of a cylindrical chamber '18, a guide member 19, and a projection .21. The actuator member ment results from an exertion of radial forces at the base .23 of the thimble because of the resiliency of the thimble material. .The engagement of the interior surface of the barrel is sufiiciently tight to form a Water-tight seal and thus=a water chamber 25 communicating with the atmosphere only through pinhole 13.
The slot 14 at the top ofthe barrel ,11 is provided at its rearward end with a parallel slit 26 to impart resiliency to the top of the barrel and the slot 14. This arrangement permits slit 26 to be spread so that guide member 19 can be pushed through the slit and snapped into slot 14, as shown in Figure 3. The front end of guide member 19 is pointed for this purpose. After being thus inserted, the cylindrical chamber 18 is telescopically slidable in barrel 11 between the forward end 28 and the rearwardend 27 of the slot 14.
It will be observed that the camera water gun is a snap assembly without the use of glue or outside fastening devices. The resilient, bulb or thimble 22 acts asa spring to push the actuator member 17 out of the barrel 11 when finger pressure is released from the rear of the actuator. The thimble 22 acts as a water container, cylinder and piston device, and a return spring. It seals itself against the front end Wall 12 and the sides of the barrel 11.
When actuator 18 is pushed into barrel 1!], elongate conical projection 21 is forced against the wall of thimble 22 as shown in Figure 4. The thimble wall is forced toward the front end of the barrel 11 and water under pressure is squirted from the water-containing chamber 24 into the atmosphere through pinhole 13. The water chamber 25 is refilled by dipping the front end of the barrel 11 beneath the surface of a body of water and releasing the pressure on actuator 17. The resiliency in thimble 22 forces its walls back to their normal, conical shape in barrel 11, as shown in Figure 2, and water is sucked into water chamber 25 through pinhole 13. Thus thimble 22 again is reloaded and barrel 11 again is extended for squirting.
It will be observed that we have provided a liquid squirting device of rugged, economical construction, designed for mass production at low material cost and for ready assembly at low labor cost.
tion in what we have conceived to be themost'practical and preferred embodiment, it is recognized that departures can be made therefrom within the scope of our invention, which is not to be limited to the details disclosed herein, but is to be accorded the full scope of the claims so as to embrace any and all equivalent structure.
