TOY AEROPLAN E.

Application filed June, 18.

The present invention relates to improve,

ments in toy aeroplanes of the type utilizing rubber bands for the propelling power, and the toy constructed according to my invention is designed for a flight of sufiicient distance to insure thenovelty and attractiveness of the toy. Means are provided whereby the toy device may be propelled, as a vehicle, along the floor or other hard surface, and in addition floats maybe attached and substi an driven as an auxiliary means to the propeller.

1 The invention consistsin certain novel com- I binations and arrangements of parts as Wlll hereinafter beimore fully pointed out and claimed. In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention wherein I have illustrated also wheel sub- H stitutes that may alternatelybe used With the toy, in which the parts are comblned and arranged according to one mode I have thus far devised for the practical application of.

the principles of my invention.

Figure 1 is a top plan view of the toy of my invention equipped as a wheeled-vehicle.

Figure 2 is a view in side elevation of the toy of Figure 1.

Figure 3 is a sectlonal View at line 83 of Figure 2.

Figure 4 is a sectional vlew at hne 4t4: of Figure 2.

Figure 5 is a detail view of a float used as a wheel substitute at the front of the toy and Figure 6 is a view of a float used as a wheel substitute at the rear of the toy, these floats being employed when the toy is used on the surface of water.

Figures 7 and 8 are side views of the front and rear runners used as wheel substitutes when the toy is used on a snow or ice surface.

In carrying out my invention I use a body or board 1 at the front end of which 1s the air propeller 2 fixed to revolve with the propeller shaft 3 that is provlded with a fly or balance wheel 4 and the shaft is journaled 1927. Serial No. 199,829.

in hearings in the walls of a gear box5 secured at the front of the board and on its top surface, the shaft of course being located in the longitudinal center of the boardand extending longitudinally thereof.

\(Vithin the b0 5 the propeller shaft is provid'ed with a pinion 6 with which a pair of gears 7, and 8 mesh, the gears being fixed to revolve with the spaced, longitudinally ex: tending driven shafts 9 and 10 locatedparallel with. and atthe sides of the propeller shaft 3 and j ournaled also in the walls of the gear housing, or box 5. This train'of gears,

extends transversely of the body, of the toy and forms the propelling or propulsion mechanism for the propeller, and the train of gears may be retained against operation, by means of a pawl 11 pivoted at 12 and provided with a counterweight or handle 12, asfor instance when the power is being developed by twisting or winding two rubber bands 14 and 1:) thatare suspended at opposite sides of the longitudinal center of the body of the toy.

These endless elastic bands, at their front ends are suspended byhooks 16 from the rear ends of the driven shafts 9 and 10, and at their rear ends aresuspended from hooks 17 on the front ends of a pair of power shafts 18 and 19. The power shafts aredisposed at the sides of the longitudinal center of the toy and j ournaled in bearings in the walls of the rear gear casing 20,and of course the power shafts are alined with their complementary driven shafts at the front of the toy. On the power shafts are pinions 21 and 22 and between these pinions is located the large gearwheel 23 on the power shaft or crank shaft 24 which is also journaled in bearings in the wall of the rear gear housing and provided at its rear end with a projecting hand crank 25. The power gear is provided with a pivoted dog or detent 26 which is shown in locked position in Figure 1 to prevent movement of the power shafts and crank shaft, as during the time the toy is being operated. To develop power, the dog 26 is released, and the pawl 11 is locked with gear 8 as shown in Figure 3 in order that by turning the crank 25 the two rubber bands may be twisted and thus store power in them.

After the power has been developed, the dog 26 is set as in Figure 1, and if the toy is to be propelled, the'pawl 11 is released, whereupon the untwisting or turning movement of shaft, a belt 28 passing around a pulley 30 and the axle 31 on which the pulley and traction wheels 33 are fixed. The belt passes through a hole 29 in the board 1 and transmits power from the propeller shaft to the axle, and thence to the traction Wheels 33, whose tractive power assist in the propulsion of the toy over the floor or ground surface. The front axle is ournaled in an under frame or wheel frame 32 of U-shape that is secured at the under side of the board anda pair of diagonal braces 34 are connected at their lower ends to a cross rod 34 fixed in the U- frame, while the upper ends of these braces pass through holes in the board and are threaded to accommodate lock nuts 35. The lock nuts are turned tight against the top surface of the board and hold the braces I through a hole in the board to accommodate the wing nut 39, and the latter is used to clamp the bracket in adjusted position to properly locate the steering wheel;

In Figure 5 a substitute for the front wheels is shown as a float supported by the float-frame 41 from the wheel frame 32, and in Figure 6 the float 42 and frame 43' are used craft and propelled by the airpropeller 2.

' In Figure? one or more runners 45 are attached at 46 to the wheel frame 32, and in FigureS one or more runners 47 are attached by frames 48 and bolts 44 at the rear of the toy as wheel substitutes, thus adapting the toy for use on ice or snow over which it is propelled by the air propeller.

These wheel substitutes form parts of the toy and are readily interchangeable with the wheels and with each other and add interest Q gears for the pinion, of a crank shaft having a gear thereon, a pair of power shafts having pinionsmeshing with thegear, and a pair of endless rubber bands suspended between the respective driving and power shafts.

2. The combination in a wheeled toy with a propeller shaft having a pinion and a pivoted pawl for engagement therewith,a pair of spaced driving shafts, and driving gears on the latter shafts meshingwith the pinion, of a" pair of traction wheels and their axle, power transmissionmeans between the propeller shaft'and axle, a crankshaft and gear thereon at the rear of the toy,'a pair of power shafts having pinions engaging said gear,'and a pairof endless rubber bands suspended between the respective driving and power shafts, and a pivoted detent for coaction with thecrank gear.

In testimony whereof affix'my signature.

WILLIAM H. DANIEL.
