Patented Oct. 31, 1950 OFFICE WATER PISTOL John William Arpin, Verona, N. J.
Application January 29, 1948, Serial No. 5,050
This invention relates broadly to a toy pistol for ejecting water, of the 'type generally referred to as a water pistol.
Water pistols of the multi-shot type are known, but most of them have been subject to various objections, such as complexity of manufacture and assembly, inadequacy of pressure, the necessity for employing specially constructed bulbs or tubes, the requirement that specially finished parts or springs be used, and other such difii'culties including the objection that the pistols did not easily lend themselves to economy in production.
According to the present invention, the foregoing and other difficulties and objections are largely overcome and a device is provided which requires no expensive finishing of parts, is very easily assembled, is rugged and effective, and is, for the most part, producible from stamped metal or molded plastic parts.
To attain these and other ends, the handle is shown as a reservoir for holding the water, and the barrel of the device isshown as carrying a resilient or highly elastic rubber tube which dips into the reservoir and extends past a compression device to a normally closed nozzle. Operation of the trigger first constricts the tube so as to close its central channel above the reservoir, and compression of the tube then follows, so that the contained water forces open the nozzle causing a forceful ejection of water. The tubing shown, may be of a single, unitary length of uniform diameter of surgical tubing, highly elastic, and. little affected by heat or cold.
The release of the trigger releases the tube so that it expands and the nozzle automatically closes. The resulting vacuum in thetube sucks up a new charge of water. The device is then ready for a second operation of the trigger, and the operation is repeated until the reservoir is empty. A large number of shots is possible because the tube is small in proportion to the reservoir. The number can be increased by using a smaller tube or larger reservoir and it is practical and very easy to provide a pistol capable of well over a hundred shots with each loading.
Other features and advantages will hereinafter operated to close the tube;
Fig. 3 is a similar view showing the trigger compressing the tube;
Fig. 4 is a sectional end View on the line 4-4 of Fig. 1.
In the form shown, the pistol includes an enlarged hollow handle I0 forming a reservoir, into which clips the end of a rubber tube I I which is bent forwardly above the water, and is held. in place by a partition I2 which closely fits the periphery of the tube so that the water in the reservoir may stand well above the horizontal part of the partition I2. The tube II is preferably but not necessarily of smaller outside diameter than the opening in the partition I2 so no packing is needed to make a tight joint.
The tube H lies in a barrel I4 so as to deliver its contained water to a nozzle I5 at its end.
In the form shown the tube, where it turns almost to horizontal, passes beneath a partition or lug I6 which extends across the pistol and holds the tube I I bent. The tube, near that point, passes over a floating lug ll forming part of a channel bar I8, which may be of aluminum or the like, so that when the channel bar I8 rises, the tube II is pinched, as shown in Fig. 2, thus closing it.
To thus close the tube II, the trigger arm I9 is pulled rearwardly, swinging the trigger around its pivot 20. In the form shown, the trigger includes a Web 2| having an upper edge or surface 22 which underlies the channel bar I8 and swings the bar I8 upwardly near its rear end, so that the lug I1 rises, as mentioned above, and begins to pinch the tube II against the fiat face of the lug I6, so as to close the tube II at that point which is rearward in relation to the discharge portion of the tube.
As the trigger arm I9 is pulled further back the whole of the channel bar I8 rises, compressing the front length of the tube II which extends between the partition I 6 and the nozzle 55, and forces Water out of the nozzle I5 with force enough to carry it many feet.
vIn thus rising, the channel bar I8 presses the tube II either against the roof 23 of the barrel, or against a false ceiling 24 which closely conforms to the natural lay of the tube II in the barrel.
In forcing the contained water through the nozzle [5, the water unseats a ball 25 which closes the outer end of a internal nipple ZBaround which the tube H is stretched at its end. The ball 25 is normally held in'a small compartment against the outer end of the nipple 26 by a coil spring 21 seated in the terminal thimble 28 of the nozzle I5, and when forcibly unseated by water the ball 25 permits the water to flow around it and through the coils of the spring 2! and out through a suitable small end perforation 29 for directing the water outwardly.
It is found unnecessary, and, in fact, advantageous not to pivot the channel bar I8, but to guide it by the depending lug IT at the rear, and to limit its travel and throw in front by a lug 39 at the forward end and a supporting lug 3I underneath its forward end. The channel bar I8 may have its top out off at 32 so that its projecting sides 33 may rise if need be on opposite sides of the tube I l where it is stretched over the cylindrical rear end of the nipple 26.
The lugs 30 and 3| may be molded integral with a side 34 of the barrel I4. Side lugs or partitions 35, 35 shown as four in number, project from that side and serve to keep the tube and channel bar in longitudinal position. The side partitions or lugs of the opposite side 31 function similarly.
The sides 34 and 31 may be separated as shown diagrammatically at 38, for ease in assembling, and the pivot 20, as shown in Fig. 4, may take the form of two half lugs 39.
For ease in assembling, the nozzle is shown as provided with a collar 40 which enables the nipple 26 to have the tube II easily slipped over it, while the other end of the tube is pushed through its opening in the partition I2.
Then the tube is laid in place against the end of partition I6, and the sides of partition 35. Then the nozzle I is laid in the opening 4| after being pushed down over the nipple 26 to the collar 40.
The channel bar I 8, with the trigger web 2| lying within it, is then laid in place, and the trigger slipped over its pivot 20 while the projecting sides of the bar I8- lie in place near or against the lugs 30 and 3|.
The side 31 may then be laid in place and held by suitable fastenings means or methods, closing the side of the slot 43 through which the trigger handle I9 projects, and may form one half side of the trigger guard 44 and the reservoir I0. It is satisfactory to make the sides as identical (except rights and lofts) parts and unite them by solvent softening of edges and pressing together to make a water tight joint.
It has been found desirable to cut the sides of the channel bar I8 as at 45 so as to permit the bar to rest, in its normal position, on the pivot lugs 39. This expedient serves to stabilize the rest position of the channel bar. It is further to be noted that whereas the absence of a positive connection for the channel bar is of particular utility in facilitating assembly and manufacture of the device, a further advantage thereof is that a great degree and symmetry of pressure may be applied to the tube inasmuch as the front end of the channel bar is permitted to rise in response to trigger actuation, a circumstance which might be impeded were a positive pivot to be employed.
The handle I0 may be provided with a filling opening 45 to receive a cork or rubber stopper 46. Either an air vent such as air vent 41 may be provided to admit air as water is expelled or the cork may have a poor fit within the opening 45 so that an air vent would be inherently provided around the edges of the opening.
While there has been described what at present is considered a preferred embodiment of the invention, it will be evident that many changes and modifications may be made therein without departing from its spirit.
