This invention relates generally to toys and more particularly to means for propelling the same.

The objects of the invention are to provide simple and inexpensive means for propelling various toys, such as boats, hydroplanes, and other objects floatable in water and to provide propelling means which do' not necessitate expert adjustmentand attention and which is inexpensive and safe to operate.

Further objects of the inventiontare to provide a power generating unit for-propelling various structures in or above water, said unit having no movable parts or valves, thereby reducing to a minimum the danger of said engine or prime mover getting out of order.

Still further objects of the invention are to rovide a boiler having pipe connections lea ing therefrom into the water, said boiler being so constructed that when heat is applied thereto the water is first drawn into said boiler and then forcibly discharged therefrom through said pipe connections,

there being no valves or movable parts utilized in the operation of said boiler, the circulation of water through the boiler being accomplished through the particular arrangement of the boiler and the pipe connections.

Additional objects of my invention are to provide an improved burner employin a suitable screen forpreventing the sprea ing of the flame and centralizing the latter under the boiler. I

With these and other objects in view my invention consists in certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed,

and illustrated in the accompanying drawings, in which Figure 11s a side elevational view of a toy boat equipped with my improved pro- .45 pelling means and burner therefor.

Figure 2 is a top plan view of the same. Figure 3 is a vertlcal transverse cross section taken on line 3-'-3 of Figure 1.

Figure 4 is a vertical'transverse cross section taken on line 4-4 of Figure 1.

Figure 5 is a vertical cross section throu hthe burner end of the boat and showing t e boiler and the burner in side elevation.

Figure 6 is a top plan viewof the boiler a; partly shown in cross section.

Figure 7 is a vertical cross section taken on line 77 of Figure 5.

Figure 8 is a to lan .view of the burner. Fi ure 9 is a detail construction of the boat balancing means.

Referring by numerals to the accompanying drawings 10 indicates an object wh ch it is desired to propel, in the present instance,

'a toy boat having a hull 11,"a keel 12, and

a removable top or deck 13, the front end -14of which is hinged at 15 to provide access to the interior of the boat. A-rudder 16 is used to steer the boat'and is formed of pliable material so that it may be bent to either side to steer the boat as desired. Hinged cover 14 is provided with a socket 17 for receiving a flag or other suitable banner .18, while the rear end of cover 13 carries an imitation gun 19 which is. swiveled thereon so that it maybe swung about its axis thereby helping to balance the boat.

' The barrel of this gun is preferably filled with lead as indicated at 20 in order to provide suitable balancing means.

A boiler 21 preferably of circular shape is arranged withinthe hull 11 and is supported therein by pipe connections 22 which are connected to said boiler and extend a suitable distance rearwardly therefrom and are then bent downwardly and extend outwardly through the bottom wallof the boat. as indicated at 23 and terminate in horizontally disposed portions 24 arranged at each side of rudder 16, as shown in Figures 1 and 2. Boiler 20 preferably comprises a bottom wall 25, annular wall 26, and top. wall 27, the latter being curved in'wardl so I that the central portion of said top wa-l is spaced only a, short distance from the bottom wall as shown in Figure 7, thereby providing an annular space 28. Pipes 22 are connected to the annular wall 26 of boiler 21 at points spaced e uidistant from the longitudinal center line 0 the boat as shown in Figure 6 and thepoints of com- 100 munication between the space 28 and pipes 22 are substantially tangentially disposed relative to the boiler. The heat is applied to the boiler by means of a burner 29 which is located in the hull 11 below boiler 21 and 105 preferably consists of a. can 30 of suitable size and filled with suitable heating medium, such as canned heat, which can be ignited through aperture 31 formed in the top wall of said can.- In order to prevent no spreading of the flames and localize the latter directly under the boiler, a screen 32 is fitted over the burner and curves upward- 1y 9'. suitable distance above aperture 31 so as to bring the heated portion of the screen moved upwardly as shown in dotted lines a in Figure 5. Cover 14 and the rear portion of deck 13 are provided with suitable ventilator openings 36 by means of which the circulation of air around burner 29 is assured. If desired, apertures. 37- may be formed in the raised portion of deck 13 at points located within the lower ends of funnels 38, thereby providing additional ventilation for the burner.

In the operation of my device, assuming that the boat is placed in the Water, when heat is applied to boiler 21, the air contained therein is expanded and is expelled through one or both'of pipes 22. The reaction produced by the expulsion of air from the boiler draws water into the boiler, which water upon being heated is discharged through one or both of the pipes 22 in a similar manner and a new charge of water is sucked into the boiler. The discharge of water from the boiler through the pipes 22 propels the boat carrying the boiler forwardly. The forcible expulsion of water from the boiler through pipes 22 will con tinue as long as heat is applied to boiler 21- and the exposed ends 24 o pipes 22 are located within a body of water. The heated water or steam may. be discharged either through both of pipes 22 or through one'of the pipes while the other pipe takes in a fresh charge of water. i

The articular construction of the boiler assists in quicklyheating the water contained therein and facilitates the circulation of water through said boiler. Burner 29 is removable b means of handle 35 so that it can be re led with the heating medium.

' While I have shown and described my invention as applied to a movableobject, it also can be used with stationary objects and in various modifications without departing from the spirit of my invention.
