3 Claims.

The purpose of my invention is to make a partially revolving mechanical toy aeroplane of a simple form of construction which will move forward in a taxiing forward motion on the ground and periodically tip by turning over onto the front end.

A further purpose of my invention is to provide a toy aeroplane for children which orientates and causes the child to be familiar with a plane.

A further purpose of my invention is to provide a mechanical means within the plane which can be operated by a key to give it mechanical motion in moving forward and turning through approximately a right angle.

Referring to drawings for purposes of illustration, in which:

Figure 1 is a top view of the aeroplane.

Figure 2 is a side elevation of the aeroplane partly in broken section.

Figure 3 is a section taken on the line 33 of Figure 2.

Figure 4 is a partial side elevation taken from the opposite side of Figure 2.

Referring more specifically to the drawing:

The shaft I is turned by a key which compresses the spring 2. At the juncture of the winding, operating spring 2 will activate the gear 3 which gear 3 will impart rotation to the pinion 4 and the larger gear 5, which is carried by the gear 4. Gear 5 meshes with a pinion 6, and pinion 6, has secured thereto, in any suitable manner a large gear 1 which drives the pinion II] which imparts rotation to the gear II and pinion I2. Pinions I and I2, and the gear II act as an additional brake on the gear train from the spring motor to slow up the advance of the toy. Pinion 6 and gear I are carried by the rotatable axle 9, which axle is rotatable in bearings 9a in opposite sides of the toy body Ia.

As the toy advances over the ground Ib it is intermittently turned through approximately a right angle in the direction of the arrow a, and during this action the upwardly and forwardly curved surface of the vehicle :body Ia engages the ground, said surface being indicated by the letter b.

The turning mechanism comprises a ground engaging fork I5, the arms Ia of which are intermittently moved downwardly so they will engage the ground Ib and raise the tail Ic upwardly and the rear wheel I 5b off the ground and the forward momentum of the body even though the wheels 8 are rotating, will cause the surface b of the body to engage the ground, but will also permit the tail to again rest on the ground when the tilting fork I5 is again raised. The tilting fork I5 is operated by a double arm rotatable cam member I6 having oppositely extending arms I'l. Cam member I6 is mounted on the shaft I which is rotated by the spring 2 and, as it rotates its arms i'I intermittently engage the lug I8 carried by the reciprocating link I9. The rear end of the link I9 is pivotally connected at 20 to the upper end of the fork I5 and is forced forwardly in the direction of the arrow 2), Figure 1, by the rotation of the cam arms IT. The upper end of the fork I5 is provided with trunnions 2|, mounted in stationary bearings in opposite sides of the body Ia, therefore it will be seen that when the reciprocating link I9 is moved forwardly in the direction of the arrow 13, the trunnions 2| being stationary, the lower end of the fork I5 will move downwardly for engaging the ground. The forward end of the link I9 is provided with an angularly disposed ear 22, slidably mounted in the elongated opening 23 in the side of the body 24. After the cam arm I! has cleared the lug I8, the free end of the fork I 5 is again raised by the contractible action of the coiled spring 25. These operations continue from time to time, and the toy will advance over the ground or surface I b and intermittently nose over onto the curved surface b. It will .be noted that when the curved surface 12 is in engagement with the ground the center of gravity will be to the rear thereof, consequently just as soon as the fork is raised, which is almost immediately, the tail end of the toy will assume its normal position with its rear Wheel I5b in engagement with the ground.

From the above it will be seen that a wheeled toy is provided which will move over the ground and intermittently nose over on its forward end. It will be noted that the gear train from shaft I to the braking pinion I2 with the toy Wheels 8 engaging the surface will brake the motor so it will slowly unwind, hence there will be a considerable pause between the periods of engagement of the cam arms I! with the lug I8, therefore it will be an intermittent nosing over of the toy.

One end of spring 25 is anchored at 26 to the rear of the body and the other at 21 to the link I9.

What I claim as new and novel is:

1. The combination with a two wheeled toy, a spring motor for rotating said wheels, said spring motor including a rotatable shaft, the forward end of said wheeled toy being rounded forwardly of the wheels, means for nosing over said wheeled toy on its rounded forward end, said means comprising a downwardly and forwardly extending surface engaging arm pivoted to the toy, a reciprocating link carried by the toy, means for guiding the forward end of said link in its movement, the rear end of said link being pivotally connected to the downwardly extending surface engaging arm rearwardly of its pivotal point and means carried by the spring motor shaft and intermittently cooperating with the reciprocating link for reciprocating the link and moving the free end of the surface engaging arm into engagement with a surface supporting the wheeled toy.

2. A device as set forth in claim 1 including 2. lug carried by the reciprocating link adjacent the motor shaft and spaced arms carried by the motor shaft and positioned to engage intermittently the lug on the link.

3. A device as set forth in claim 1 wherein the 4 means for reciprocating the link comprises a radial arm carried by the motor shaft, a lug carried by the link in the path of said last named arm and a spring cooperating with the link for normally urging the link rearwardly and the free end of the surface engaging arm upwardly.
