MECHANICAL AIRPLANE TOY.

Application field November This invention relates to improvements in mechanical airplane toys.

The main object of this invention is to provide an inexpensive and effective toy to simulate an aviator effecting a nose dive.

Another object of this invention is to provide a toy airplane that will describe an arc of approximately 180 degrees at each dip or nose dive.

Other objects and novel features of my invention will be apparent as the description proceeds.

Referring to the drawings forming part of this specification:

Figure 1 is a side view in elevation showing an embodiment of my invention. The dot and dash position shown in this figure illustrates the position of the toy while making the nose dive.

Figure 2 is a botttom plan view of the driving mechanism.

The class of toy here described consists of a body portion 3, made of sheet metal. A winding key 4 at the forward end of the toy is utilized to wind up the driving mechanism generally referred to as 5, a spiral power spring 6, attached to an extension or rod 7 forming a part of the winding key.

The usual drive gear 8 suitably mounted on the key rod 7, is actuated by the power spring 6, and in turn drives a pinion 10 fixed to a shaft 11, at the upper end thereof. A mutilated gear 12, is fixed to the lower end of said shaft 11, and meshes alternately with pinions '14, and 15, fixed to an axle 16. A wheel 17 is revolvably mounted at the rear of the toy as at 18, this wheel tends to maintain the toy in normal horizontal running position.

When the spring 6 is wound up it will tend to drive the gear 8 in the direction as, indicated by the arrow and thus impart a movement to the mutilated gear 12 in an opposite direction through the medium of the pinion 10, which is secured to the shaft 1.1, that also holds the aforementioned gear 12. F orward motion to the toy is imparted by means of the pinion 14, fast to shaft 16, said shaft 16, also having securely fixed thereto a wheel 20, at one end thereof. The shaft 1.6 has at its other end a loosely mounted wheel 21.

The body and driving mechanism of my toy are so balanced and tending to stop the forward movement of the to will cause the forward end thereof to dip ownwardly and 14, 1825. Serial No; 68,973.

raise the rear or tail end inan upward direction.

It will be understood that the toy will have forward motion only as long as the mutilated gear 12, is in mesh with pinion 1 f, fixedly mounted to shaft 16, said pinion 1.4 imparting rotative movement to the shaft 16 and wheel 20 fixed thereto. When the teeth on gear 12 become unmeshed with the gear 14, they will become engaged or mesh with the teeth on pinion and tend to stop the forward movement of the toy and impart a rearward movement thereto. This tendency will cause the forward end of the toy to dip down, and owing to the fact that the wheel 21 is loosely mounted on the shaft 16, the toy will describe a semicircular are, the loosely mounted wheel 21 acting as a pivot, while the wheel is moving rearwardly. In order that the front end 22, of the toy does not strike the floor in its dipping position and thus defeat the object of my invention, I provide a wheel 23 loosely mounted on a pin 24, in a forked bearing 25, pivotally mounted on a depending rod 26, at the front of the toy.

When the mutilated gear 12 again comes into mesh with the pinion 14, the toy will then again be propelled in a forwardly direction. This action will be repeated until the power spring 6 needs rewinding.

Having described my invention what 1. claim is:

1. A mechanical toy comprising a body, a motor for propelling said body in a forward direction, reversing means in said motor to cause the toy to simulate a nose dive, means for simultaneously describing a semicircular movement with said nose dive simulation, and means for returning the body to normal position.

2. A mechanical toy comprising a body, an upwardly tilted portion at the front of the body, a motor mounted in. the tilted front portion, an axle upon which the body is pivoted associated with the motor, ground engaging wheels on the axle and a reversing mechanism in the motor to cause the body to tilt in a downwardly and forwardly direction at predetermined intervals and then return the body to normal position.

3. A. mechanical toy of the nature described comprising a body, an axle upon which the body is adapted to be pivoted, a pair of ground engaging wheels on the axle, a front portion on said body overhanging beyond theaxle, a reversing motor mounted in the said front portion adapted to alternately propel the toy in opposite directions and to simultaneously cause the toy to dip forwardly due to the jar caused by thereversal of the motor.

4. A mechanical airplane toy, adapted to periodically simulate a nose dive, comprising a body, an upwardly tilted portion at the front of the body, a reversing motor mounted in the tilted front portion, an axle journaledin the body, a mutilated gear on said motor, a plurality of pfnions fast on the axle alternately in engagement with the mutilated gear, a ground engaging wheel fast to one end of the axle, a second ground engaging wheel loosely mounted on the opposite end of'theaxle, a wheel at the rear of the body normally in engagement with theground, and a pivotally and revolvably mounted wheel at the front of the body to engage the ground when the toy is simulating a nose dive.-

In testimony whereof I hereunto afiix my signature;

DAVID HEYMAN.
