TOY BOAT Filed March 3, 1958 INVENTO ROBERT 0. A/'I/l A rive/v5) United States Patent TOY BOAT Robert 0. Nevitt, Seattle, Wash.

Application March 3, 1958, Serial No. 718,610

'6 Claims. (CI. 46-93) My invention relates to a toy boat and more particularly to a toy boat which will emit a fan-like spray or rooster tail when the boat is towed or pulled while riding on the'surface of a body of water.

There is a need, around wading pools and the like, for fascinating floating toy boats to amuse the tots or small children and keep them occupied and the satisfaction of such need is an object of my invention.

Another object of my invention is to provide a toy boat which will emit a fan-like spray or rooster tail so that the children will continue to be satisfied and thus provide a toy which will be used day after day.

Another object of my invention is to provide a toy which is inexpensive to produce and which at the same time has such realistic action that the device is readily saleable, wanted by children, and readily used by children.

Other objects and advantages of my invention will become apparent as the description of the same proceeds and the invention will be best understood from a consideration of the following detailed descriptions taken in connection with the accompanying drawings forming a part of the specification, with the understanding, however, that the invention is not to be limited to the exact details of construction shown and described since obvious modifications will occur to a person skilled in this art.

Figure 1 is a view in side elevation and with parts broken away and in section of a device embodying my invention;

Fig. 2 is a sectional view taken substantially on broken line 22 of Fig. 1;

Fig. 3 is a bottom plan view;

Fig. 4 is a perspective view of the conduit or water tube (shown in Figs. 1, 2 and 3) just after cutting;

Fig. 5 is a perspective view of the tube or conduit of Fig. 4 after the trailing end portion thereof has been flared;

Fig. 6 is a perspective view of the tube of Fig. 5 after said flared trailing end portion has been flattened to provide a slot-like nozzle; and

Fig. 7 is a view similar to Fig. 4 of a modified form of conduit or water tube; and

Fig. 8 is a perspective view of the tube shown in Fig. 7 after the trailing end portion of said tube has been flattened to provide a slot-like nozzle.

Referring now to the drawings, the boat hull 10 is preferably provided with a tail fin 12 so that in general appearance the hull and fin will resemble a modern hydroplane. On the bottom of the hull 10 is a groove 14 which extends longitudinally of, and substantially centrally of, the bottom of the hull 10. This groove 14 is plugged by portions of the bottom of the hull or by extending the groove 14 the full length of the hull and then plugging it so that the groove 14 terminates short of the trailing end portion of the hull 10.

A hole is drilled at an angle of substantially 45 to the plane of top of the groove 14and receives therein a conduit or water tube 16. The forward end portion 18 is preferably cut at a 45 angle so that when the tube is installed as shown in Fig. 1, the said end portion 18 will be normal to the surface defining the upper wall of the groove 14. The other end portion of tube 16 is preferably cut normal to the axis of the tube 16 to provide the trailing end portion 20. Preferably the said trailing end portion 20 of the tube 16 is flared to provide the flared portion 22 illustrated in Fig. 5 of the drawings. Next said flared portion 22 is flattened over a die or thickness gage so that the thickness of the slot 24, in the flared and flattened end portion 26, will have a dimension in thickness from about 0.010 to about 0.020".

When in operation a. suitable towing means is secured to the eyelet 28 and the hull 10 is propelled by pulling or towing through suitable means, such as a long string and a long rod (not shown). Due to the relative motion between the water indicated by 30 and the bottom of the hull 10, water delivered to the groove 14 passes into conduit 16 and is emitted out the slot 24, functioning as a nozzle, and the pattern of the spray is a fan-like spray indicated by 32 in Fig. 1 of the drawings. In view of the fact that the slot 24 when installed is in a vertical plane, the face of the fan-like spray lies substantially in a vertical plane.

As an alternate construction of a conduit means having an integral nozzle, I have shown in Figs. 7 and 8 a tube or conduit 34 which has a forward end portion 36 and the trailing end portion, as indicated in Fig. 7, is normal to the axis of the tube 34 when cut. After cutting the trailing end portion 38, a slot or kerf 40 is provided on a diameter of the tube 34 and alined with a diagonal from the lowest to the highest portion of the diagonal forming the forward end portion 36. Then a die or thickness gage is employed and the trailing end portion 38 is flattened over said die to provide a slot 42 with kerfs 40 at the end portions thereof. The slot 42 functions similarly to the slot 24. In addition the kerfs 40 have the eifect of further spreading or increasing the face area of the spray 32 over that provided by slot 24.

It is preferable to provide a fan-like spray with the lower portion of the spray contacting the wake 44, produced by the relative motion of the hull 10 and water 30. This is facilitated by the angle of the conduit 16 and the pattern of the spray from a particular nozzle.

As an example, and not as a limitation, I have built a toy boat embodying my invention having an overall length of about 8 to 10 inches; the widest beam of the hull was 4 to 5 inches; the narrowest beam of the hull was approximately 2 to 2 /2 inches; the groove 24 had a height and breadth of approximately 4 to 7 of an inch; the tube 16 had an OD. dimension of approximately of an inch; and the slot 24 had a thickness of approximately 0.010 inch to about 0.020 inch and had a length of approximately M2 to A: of an inch.

Obviously changes may be made in the forms, dimensions and arrangement of the parts of my invention, the foregoing setting forth only preferred forms of embodiment of my invention.

I claim:

1. Toy boat comprising a boat body having a groove extending longitudinally of, and substantially centrally of, the bottom thereof; plug means terminating said groove short of the trailing end portion of said boat body; and a conduit extending angularly upwardly and rearwardly with the forward end portion connecting with said groove and the trailing end portion terminating in a nozzle for forming a fan-like spray with the face of the spray lying substantially in a vertical plane.
