STOP-MOTION FOR MECHANICAL TOYS.

SPECIFICATION forming part of Letters Patent No. 701,155, dated May 27, 1902.

Application filedlVIarch 26, 1901. Serial No. 52.942. (No model.)

To all whont it may concern:

Be it known that'l, ATHERTON D. CON- VERSE, a citizen of the United States, and a resident of Vinchendon, in the county of Worcester and State of Massachusetts, have invented a new and Improved Stop-Motion for Mechanical Toys, of which the following is a full, clear, and exact description.

My invention relates to a stop-motion for mechanical toys; and the purpose of the invention is to provide a simple, durable, economic, and effective means whereby when the motor of a mechanical toy is wound up the motor will not act upon the axle or wheel of the toy with which it is connected until the toy is brought in contact with the support upon which it is adapted to travel.

A further purpose of the invention is to provide a means whereby the motor connected with the vehicle, especially a toy vehicle, will be brought into action by the weight of the vehicle when the vehicle rests upon the surface over which it is to travel and whereby the motor will not act while the wheels of the vehicle are out of engagement with a track or other surface.

The invention consists in the novel construction and combination of the several parts, as-will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a toy vehicle and the improvement applied thereto. Fig. 2 is a rear elevation of the vehicle and the improved device,illustrating the stop-motion out of action. Fig. 3 is a view similar to Fig. 2, but illustrating the stop-motion in position to check the operation of the motor employed. Fig. 1 is a section on theline 44of Fig. 2, and Fig. 5 is a section on the line 5 5 of Fig. 3.

A represents the body of the vehicle; B and O, the axles; D, the supporting-wheels secured to the axles, and E represents a springmotor which motor is connected with the axle B through the medium of gearing 10 and 11, as shown in Figs. 1, 2, and 3. Theframe 12 of the motor E is loosely mounted on the axle B, at one end while the other end of the frame 2 of the motor is pivotally connected with thebottom portion of the vehicle-body or body of the toy by means of a hanger 13 of any description.

The pedestals 15 for the axle B are proends of the slots 14 in the pedestals 15. One of,

the pedestals 15 is provided with inwardly pointed or tapering stop-lugs 16, and,as shown in Figs. 2 and 3, this lug usually. occupies a horizontal position. The stop-lug 16 is adapted to engage with one of the teeth 18 of a ratchetwheel 17, the ratchet-Wheel being secured to the axle B, and such engagement occurs when the vehicle is raised from the support on which it is to travel, and the weight of the motor forces the axle B downward. When such a contact occursbetween the stop-lug 16 anda tooth of the ratchet-wheel17,.the motor, even when its spring iswound to its utmost,-will'have no influence on the driving-axle B,thus preventing the waste of power which usually occurs during the interim of windingthe motor and placing the wheels of the toy or vehicle on the support upon which it is to travel. It will be understood that instead of the ratchet wheel one or more projections may be formed upon the axle to engage the stop-lug 16.

Under the improved construction shown tion in Fig. 3 and out ofaction in Fig. 2.

It will be observed that the stop-motion above described is exceedingly simple and economic and that it is applicable to any toy which is operated by a motor of any description or which is to travel upon wheels. I desire it to be understood that the character of the motor may be varied at will.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A vehicle provided with a motor for imparting motion'to sundry of the wheels, and a check for the wheels, brought into and out of action by raising the wheels of the vehicle from or bringing said wheels into engagement with a supporting-surface.

2. In mechanical toys, at motor-controlled driving-axle having movement to and from the body of the vehicle to which it is applied, and a check for the motor, operated by the movement of the axle, as set forth. 1

3. In mechanical toys, a driving-axle for a vehicle, a motor for the driving-axle, a projection from the axle and a stop arranged for engagement with the projection, the projection and stop being automatically brought intoengagementwhen the vehicle is placed upon a surface upon which'it is adapted to travel, said stop and projection being immediately carried out of engagement when the vehicle is raised from said surface, the engagement of the stop and projection serving to prevent an expenditure of power on the part of the motor.

4. A driving-axle fora vehicle, a motor having driving connection with said axle, the motor having movement to and from the vehicle-body, a stop carried by the fixed support, and a projection from the driving-axle, ar-

ranged for engagement with the said stop and for disengagement from the stop through the weight of the vehicle with which the axle is connected.

5. A driving-axle for a toy vehicle, a fixed support for the axle, in which fixed support the said axle has sliding movement, a stop carried by one of the said supports, a projection from the axle, adapted to engage with the stop when the axle is in one position, the said stop being out of engagement with the projection from the axle when said axle is in its other position, and a motor connected with said axle, as described.

6. In toy vehicles, the combination, with the body of the vehicle, axles for the same, the driving-axle having movement in its pedestals to and from the body, of a motor connected with the driving-axle and having pivotal connection with the body of the vehicle,

motor, whereby said axle is rotated and thevehicle propelled, said axle being capable of a rising-and-falling motion relatively to the said body, a ratchet carried by said axle, and an arm arranged to engage said ratchet as the axle falls, and check its rotation, substantially as described.

8. The combination, with a vehicle-body having a motor, an axle rotated by said motor, a ratchet on said axle, a locking-arm for engagingsaid ratchet, means for moving said axle away from said body and carrying said ratchet into'engagement with said lockingarm, substantially as described.

9. The combination, with a vehicle-body, of a rotating axle, means for moving said axle relatively to said body, and means for locking said axle from rotating when it is moved away from said body, substantially as described.

, 10. The combination of a vehicle-body having slotted lugs, an axle held in said slotted lugs, whereby said axle is capable of moving toward or away from said body, wheels attached to said axle, one of said wheels having ratchet-shaped teeth, an arm arranged to engage'said teeth when the axle is moved away from said body, and means for rotating said axle against said arm, substantially as described.

11. In a toy vehicle, the combination with a body and an axle carriedby said body and catpable of a falling motion as the body is raised, of a motor applied to propel the vehicle, and

means con trolled'by said falling axle to check the movement of the vehicle, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of .two subscribing witnesses.

ATHERTON D. CONVERSE.
