The toy of the present invention is of the type in which a miniature airplane, normally resting on the ground is connected to one end of anormally inclined counterweighted lever1V rotatably fulcrumed intermediate its ends on the top of a stationary column. The airplane motor drives a toy propeller which moves the plane over the ground'atvsuch a speed that ythe centrifugal force developed,

coupled with the lifting action of the propeller is sufficient to overcome gravity and cause the plane to rise and fly in a circular path,

turning the leverfaboutthe column. This action is, of course, asslsted 1n large measure by the counterweight whichis preferably so proportioned that even a small centrifugal force will tend to swing the ylever to horizontal position.

One object of the invention is to provide a toy of this character in which the counterweight simulates an aircraft, so that when the device is in motion there will appear to be twol aircraft flying in circular paths about the central column, which may be convenientlydesigned to simulate a mooring mast or lighthouse if desired. p

Another object of the invention is to provide an improved simplified construction of airlplane which will be realisticin appearance.

l nother object'of the invention is to improve vand simplifythe construction ofthe lever and its rotatable fulcrum. Preferably the lever lcarries its own fulcruming n pin adapted to be removably mounted in a socket Y in the column, and the use ofa projecting pin y ijn the column'which might seriously injure a child falling upon it is entirely avoided.

Further and more general objects of the invention are toy provide a toy of simple practical construction, which will be rugged, durable and eiicient in use, which will provide amusement anddiversion for both old and young observers, which may be conveniently setup and operated by a child and whichis well suited to the requlrements of economical manufacture.

Ihe invention may be more fully understood from the following description together with' the accompanying drawings, which are illustrative of only oneof the preferred em- PATENT OFFICE CAL TOY 1927. vserial No. 172,232.

Referring to Fig. 1 in a general way I have used the numeral 10 to designate the central supporting column on the top of which is rotatably fulcrumed the lever 11. Detachably connected to opposite ends of the lever are the motor driven toy airplane 12 and the counterweighted toy'aircraft 13, the latter preferably simulating a dirigible and being slightly lighter. than the former which normally rests upon the' ground and maintains the lever `in the tilted position tol elevate dirigible L 13.

Supp @Ming column Cil p and may simulate the observation platformsv i the column,

wide base renders it diiiicult to tip the column over. A cap piece 18 closes the top of the column and a substantially hemispherical hollow dome member 19 is mounted on the top of the cap. The cap may be attached to the dome and column by the tongue and slot connections-so well'known in the sheet nieta-l toy art andthe cap and dome are formed with aligned central openings 20.

Operation In operation the column 10 is set up upon any suitable flat surface such for instance as the table 90, the lever 11 is unfolded and the fulcrum pin 29 inserted in the openings 20. Dirigible 13 is hooked on one end of the lever 11. The motor of the airplane 12 is wound and the plane engaged with the other end of the lever, the weight of the airplane 12 slightly predominating so that it will rest on the table 90 and elevate the dirigible as seen in Fig. 1.

As the propeller 37 (which has been manually held against rotation while winding the motor and attaching the plane to the lever) is released it will act to draw the airplane 12 forwardly moving it in a circular path over the table about the column 10 as a center and initiating rotative movement of the lever 11 on its fulcrum. Most of the weight of the airplane 12 is sustained by the counterweighted dirigible 13 so that the propellerl will have but little friction to overcome when starting and maintaining rolling movement of the wheels 42, 43 over the surface of the table.

The centrifugal force developed by the circular travel of the airplane coupled with the slight lifting action of the propeller on wing 44 causes the plane to gradually rise above the surface of the table until the lever 11 assumes the substantially horizontal position illustrated in dotted lines in Fig. 1. Rotation of the toy will continue with the lever in this position until the motor slows down and the plane loses momentum at which time the plane will gradually settle down onto the surface from which it rose.

The taking off, flying and landing of the plane is very realistic and amusing t0 watch. The use of the dirigible adds to the natural appearance of the toy particularly while the plane is in flight.

In Fig. 9 is shown an alternative form of airplane embodied as a bi-plane instead of a monoplane. For this purpose, the fuselage 31 has its extension ears 38 extending downward through corresponding slots 382 in the I lower wing (w. Spars 75 are struck up from the lower wing, leaving openings 76 therein, said spars stiffened by bending longitudinally for a channel beam conformation, which includes lateral wings 77. The upper ends of the spars are attached to the u per wing 44, preferably by soldering (not s own) In the present embodiment I have also indicated a novel form of brake, which, of course, is applicable alternatively to the monoplane construction of Figs. 4 and 5, or the bi-plane construction of Fig. 9. This brake comprises a length of wire 78 extending formed 'as a reversel'ylbent loop 81 extending through an elongated slot 82 in the forward end of the fuselage bod said loop .81 extending whenthe brake fiandleis pushed to 'the operative position sho'wn,vin lthe path of rotation of the propeller 3 7. When thehundlewSO is pushed back to ,thel opposite extremity' of its slot, the end ofthe forward part 81 is drawniout of the path of Irotation ofthe propeller. The `forward end of the brake member' being rounded 4will not-become interlocked with the propeller `should it be advanced vwhena part of the propeller is in the path thereof. The rear or handle end of the,A operating member frictionally en- 'gagesrthe fuselage body so that saidv brake member will be frictionally or impositively heldin any setting thereof. ylVith thebralre construction shown, it will be seen that the winding of the motor isfacilitated and the airplaneV body can be deposited upon the ground on starting the toy, without having to hold the propeller, the latter being released by simply drawing the brake handle 80 rearwardly.

'Obviously various structural modifications might be resorted to within the spirit and scope of the appended claims.
