POWER-PROPELLED BOAT.

Application led Ju'ne 25, 1924. Serial No. 722,389.

This invention relates to boats and watercraft that may be propelled in water, especially'toy boats, and has reference particullarly to simplified means for propelling t em.

An object of the invention is to providev a power-propelling Ymeans of such simple construction as to permit operation and control thereof byvthe unskilled and notl require machinery that might be a source of trouble and cost forrepairs.

Another object is to provide an improved and inexpensive toy boat,4 and especially propelling means therefor, of such construction as to be adapted to be safely operated by children, and which may be educational, attractive and amusing.

A further object is to provide simple and inexpensive means for the propulsion of boats in water which shall include-'a vibratory boiler requiring water for operation and designed to be automatically supplied with water in operation, to relieve the operator of trouble incidental to supplying the requirements.

A still further object is to provide a very simple and inexpensive toy boat that may be retailed at low cost, and which in operation shall imitate the sounds produced by the explosions 'in internal combustion engines, especially when discharging in water, andwhich may be inexpensively operated and not liable to become deranged or require repairs, but which shall be durable and ,economical in use.

With the abovefmentioned and other objects in view, the invention4 consists in certain novel propelling apparatus having an improved conduit arranged in a novel manner for expelling or receiving water, anda novel boiler adapted to operate to cause alternate in-iiow and out-How of water whereby to force a boat forward in water; and,

the inventionI consists also further in the parts and comblnatlons and arrangements of parts asy hereinafter particularly des scribed and further set forth in the claims appended hereto.

Referring to the drawings,-Figure 1 is a side elevation of a boat constructed substantially in accordance with the invention and provided with the novel propelling means; Fig. 2 is a longitudinal vertical sectionalelevation of the boat and propelling apparatus; Fig. 3 is a top plan of the boat partially broken away; Fig. 4 is a transverse sectional elevation approximately on the line IV-IV on Fig. 2; Fig. 5 is a vertical longitudinal central section of a boiler` of preferredtype adapted for carrying out the objects of the invention; Fig. 6 is a transverse section on the line j VI-VI on Fig.l 5; and Fig. Y is a transverse section of a heater and fuel for heating the boiler, the plane of the section corresponding approximately to the line IV-IV on Fig. 2.

In the various figures of the drawings similar reference characters indicate corresponding elements or features of construc tion herein referred to particularly in the detail description following.

The construction, application, and the mode of operation of the invention is, for the purposeof disclosure of the invention, shown as it relates to a boat which may be of-small size as a toy, the boat illustrated in this case includino` a hull comprising bottom portions l an 2 composed of thin sheet metal having median portions pressed out to form sides 3 and 4 and a bottom 5 of a hollow keel, the hull comprising also upper side portions 6 and 7, a bow Sand a stern 9. The rear end of the keel is closed and a rudder l0 is connected thereto, the rudder preferably beingcomposed of bendable sheet metal, so that it may be set to guide the boat in either a straight course or a circle. y yThe upper portion of the hull preferably has a band or belt 11 struck up to laterally stili'en the top of the hull and improve the appearance thereof.

A deck is separately made of sheet metal and comprises a main and forward arch portion 12 and a fiat or nearly at stern portion 13, there being an opening or hatchway 14 between said two portions, the metal at the edge of the opening being turned inward to form a frame 15. The marginal portion of the deck is fitted to the top edge of the hull and has a liange 16 thereon that extends downward over the upper portion of the hull. The rearward ,end of the deck portion 12 has a stifl'ening ange 17 integral therewith. The deck may be secured to the hull by various -means, preferably a suitable number of lingers 18 integral with portionV of the deck has a longitudinal slot 20 therein for ventilation and to permit sounds to passthrough the deck.

The propelling means or engine as prefon having a ledge 25 at its top upon which` a suitable gasket 26 is arranged` The body portion of the boiler preferably is composed of stamped sheet metal, and a separate thinner sheet metal top plate 27 is-arra-nged upon the gasket and secured in place by means of a flange 28 formed of the side wall metal turned over tigl'itly upon the plate, this mode of fastening being preferable to soldering the plate-to the ledge. The plate 27 is composed of thin sheet metal, so as to operate somewhat like a diaphragm, and to improve its qualification for vibratory action the central portion is gently beaten on its inner side to slightly expand the metal and cause a bulge portion 29 which is scarcely perceptible to the eye yet causes the metal to spring outwardly after having been pressed or drawn inwardly. The interior of the boiler preferably has a stop device to limit .the inward movement of the top plate 27, especially when roughly handled, and the device may be cheaply made by pressing u form a hol ow rib 30 under the middle portion of the top plate. A nipple 31 is tightly secured in the bottom-24 and is removably inserted in the stand-pipe 23, permitting the boiler to be turned slightly towards either side of the boat to balance the boat in case it is so desired, orto list the boat if desired.

A suitable heater is provided which requires a holder on the bottom of ths hull, andin the present case the holder is composed of sheet metal stamped out of the deck when-making the opening 14, so that a base plate 32 is provided which is arranged back of the stand-pipe 23 and soldered or otherwise secured upon the pipe 21, the base plate having upstanding side guides 33 and 34 and an end stop 35. A reservoir or fuel holder is provided with .comprises a bottom 36 and a s'ide wall 37 thereon, and a top plate 38 upon the wall and having an aperture 39 therein from which a flame or heat may escape below the boiler for heating water therein. A figure 40 is secured to the top Aplate 38` tov constitute a handle for the heater and -preferably represents a human operator of the boat.

In the present case a block or piece of al portion of the bottom 24 tonon-liquid or solid fuel 41 is arranged in the fuel holder which when ignited will slowly burn and supply the required heat, but obviously the heat may be produced from other forms of fuel if desired.

In the factory it is customary to supply tlie boiler with water which is retained therein by placing a stopper in the conduit terminal portion 22 to be removed after placing the boat in water for operation.

In practical use, the boiler being lled with water and heat produced under the boiler, the water in the boiler becomes heated and produces steam which is forced into the standpipe 23 and into contact with cold water therein andin the pipe 21. The steam on coming into Contact with the cold water rapidly condenses, thus causing vacuum in the boiler and conduit with the` result that water is drawn in and meets the hot wat/er in the boiler in which reaction occurs, so that while partial vacuum exists the heated Water expands and drives out` the water from the `pipe or conduit, being followed by hot vapor or steam which condenses when coming into contact with the cold water as before. The complete cycle is repeated indefinitely until the heat becomes exhausted. The water in which the boat is floating is drawn from all angles slowly into the terminal portion 22 of the conduit so as to not affect the movement of the' boat, but the charge of water is forcibly expelled in solid stream into the body of water, which forces the boat forward. During the opera? tions the pulsations cause the boiler top to vibrate, as a diaphragm, producing the desired sounds similar to the exhaust of steam from an engine or exhaust from anexplosion engine, 'and the intermittent discharges from the terminal portion 22 of the conduit suggest the exhaust 'of explosion engines when discharging in water. -lVhen it is desired to discontinue operations a stopper is to be placed in the conduit while under water,l to retain water in the conduit and the boiler ready for subsequent operation.
