JET PROPELLED TOY BOAT Filed Deo. 5, 1945 Attorneys Patented June 13, 1950 JET PROPELLEDV TOY BOAT Quentin L. Briggs and Raymond A. Voyls, Fort Wayne, Ind., .assignors to Chicago Musical Instrument Co., Chicago, Ill., a corporation of Illinois Application December 5, 1945, Serial No. 632,843
(Cl. i6-9.5)
8 Claims.
AThe invention relates. generally to floating toys and more particularly to a Alioating toy which is self-driven.
The general object .of the invention is to provide a `novel toy adapted Sto be floated in a body of water and to be self-drivenrwithout the use of any moving parts.
Another object is to provide a novel vselfdriven floating toy Y.which utilizes the jet vaction of a stream of water to produce the driving action and which is provided with a tank for such water, held by `the buoyancy of the toy in .such position as to'produce a stream of this character.
A further object is to .provide a novel' selfdrlven'floating vtoy in the form of a boat which is caused to be propelled merely by first submerging it in a ibody of water and then releasing it.
Other objects and advantages will become apparent from the following description taken in connection with the accompanying drawings, in which:
Figure 1 is a perspective view of a toy boat embodying the features of the invention.
Fig. 2 is a, longitudinal sectional view of the boat shown in Fig. 1.
Fig. 3 is a transverse sectional view taken on the line 2-,2 -of Fig. 3.
A floating toy of the character herein disclosed is adapted to be self-driven without the use of any moving parts to .effect the driving action. Inthe preferred embodiment, .the toy has the form of a boat, but the invention is not limited to a boat but may be embodied in other forms. The toy is adapted to be floated in a body of vwater and comprises .generally a water tank preferably adapted to be vfilled with water by submergence therein, and buoyant means to support the tank so that the level of water therein is higher than the level of the body of water. The water tank is provided with a jet outlet lpositioned below the level of the body of water so 4that the water in the tank will flow therefrom and by a jet action will drive the toy. The tank has an openingv at its top which permits'v filling thereof Vby ,submergence in the body ofy water and also permits air to readily enterfthe tank as the water flows therefrom through the jet outlet.
, When the invention is embodied in a boat, the hull is so formed as to provide a water tank portion -anda buoyant portion, here shown as being in the form `of a closed air chamber to maintain .the tank and consequently the level of the water therein in a position abovexthe level of the water outside of the hull. The jet outlet of the tank, of course, is directed rearwardly through the stern 2 0f the boat at such level that it is always below the level of the body of water, to produce a jet action causing the boat to be propelled forwardly.
To illustrate the invention, we have shown in the drawings one embodiment which is in the form of a boat comprising a hull, indicated generally at I0. The hull I0 may be given any desired external appearance and shape but comprises a buoyant means in the form of an air chamber portion II and a tank portion I2. The air chamber portion II is `completely closed to cause the boat vto yfioat on the surface of a body of water. The air chamber portion II is also so related to the tank portion I2 that the latter is held in a position such that when water is placed therein the level of the water will be a substantial distance above the level of the body of water in rwhich the boat oats. Thus, the air chamber portion may generally be said to be located in the lower portion of the hull while the water tank portion is located in the upper part thereof, and in the embodiment illustrated vin the drawing the air chamber II extends under the water tank I2, as shown in Figs. 2 and 3.
To effect propulsion of the boat, the water tank I2 is provided with a jet outlet I3 opening rearwardly from the hull and at a low point therein so that it will, preferably at all times regardless of the quantity of water in the tank I2, be below Ythe surface of the outside water. Water may thus ow from the tank I2, since the level thereof is held above the level of the outside water, through the jet outlet I3 and thereby propel the boat forwardly.
The tank I2 is preferably lledwith water merely by submerging the boat in the body of water in which it is to float. To this end, I provide an opening I4 in the top of the tank. The opening I4 is preferably of quite substantial size so that the tank may be quickly filled merely by holding the boat submerged for a few seconds. When the boat is floating, the opening I4, of course, vserves to permit air to enter the tank I2 as the water flows therefrom through the jet outlet I3. In the particular construction herein shown, lthe tank I2 is provided with a drain portion I5 extending downwardly therefrom to .the jet `outlet I3 so that the major water carrying portion of the tank `is substantially above the bottom of the boat. The hull rmay be provided with a keel I6, if desired, to assist in preventing the boat from tipping. The air chamber II is also so proportioned as to assist in maintaining the boat on even keel, by extending laterally beyond the sides of the water tank I2, as clearly shown in Fig. 3.
The external appearance of the boat may obviously be widely varied. ln the present instance, the air chamber portion II extends laterally to provide sloping decks 20. The tank I2 in this instance, while extending partly below the level of the decks 20, also extends thereabove and is given an external appearance simulating the cabin or trunk structure of a speedboat or the like, as indicated at 2| in Fig. l.
In using the toy, the entire boat is submerged in the body of water in which it is to oat, to such an extent that the opening I4 is below the level of the body of water. Thus, the tank I2 may be quickly iilled. As soon as such iilling has taken place, the boat is released, and the air chamber portion II causes the boat to rise to the surface of the body of water, such position being indicated in Fig. 2. The level of the water in the tank I2, as indicated at 22,` is substantially above the level, indicated at 23, of the body of water outside of the hull. Thus, the water within the tank I2 will iiow outwardly through the jet outlet I3 to produce a jet action propelling the boat forwardly. As the water flows `from the tank I 2, the level 22 therein is, of course, lowered but the buoyancy compensates for such lowering of level by causing the boat to ride higher in the outside body of water, thus maintaining a sufficient difference in level between the water in the tank and the outside water to cause a continued How through the jet outlet I3. In the particular boat illustrated in the drawings, the buoyancy of the air chamber II is suiiicient to cause the water level in the tank I2 at all times to be above the level 23 of the outside water. The tank I2 will thus drain completely with its maximum capacity of water entirely utilized for propulsion of the boat, except, of course, for the small quantity of water remaining in the drain portion I5.
From the foregoing description, it will be apparent that I have provided a self-driven toy in which the driving action is elected without the use of any moving parts. The boat is conditioned for propulsion merely by submerging it to iill the tank I2 and then releasing it, the buoyancy of the boat causing it to rise to the surface. When the boat reaches the surface after release, the level of the water in the tank I2 is substantially above the level of the body of water in which the boat is floating, so that the water in the tank lows therefrom through the jet outlet to propel the boat forwardly.
We claim:
