EMERIGH SABINA AND ALEXANDER WEINBERG, 0F PITTSBURGH, PENNSYLVANIA.

' MECHANICAL TOY.

Application filed March 20, 1918.

T 0 all whom it may concern:

Be it known that we, EMERICH SABINA and ALEXANDER \VEINBERG, citizens of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Mechanical Toys, of which the following is a specification.

The prime object of our invention is to provide a new and improved mechanical toy.

In the accompanying drawings, which illustrate an application of our invention,

Figure 1 is a side elevati'onal view of a mechanical toy constructed in accordance with our invention;

Fig. 2, a central vertical sectional view thereof;

Fig. 3, a top plan;

Fig. 4:, an enlarged detail view partly in elevation and partly in section, the section being taken on line H of Fig. 3; and

Fig. 5, an enlarged sectional detail view, the section being taken on line 5-5 of Fig. 3.

Referring to the drawings, 1 designates a base preferably made of sheet metal and clesigned to support the entire structure.

As illustrated and as preferred, the toy includes an elevated tilting track 2, a lower divided track comprising a stationary inclined portion 4: and a tilting inclined portion 5, upon .which a carriage 3 runs. The elevated track 2 is pivotally supported on a cross piece 6, as indicated at 7, and said cross piece in turn is carried on uprights 8 projecting upwardly from the base.

Fig. 2 shows the elevated track in tilted position, movement of the track to this position being effected by the weight of the carriage after the carriage has passed the fulcrum point. It will be understood that as soon as the carriage leaves the track 2, the track will return to the position shown in Fig. 1. For the purpose of supporting the track in the position shown in Fig. 1, we provide a cross member9 supported on members 10 extending from the base.

The stationary portion 4 of the lower track is supported from the base by means of members 11 and 12. The cross sections of the elevated and lower tracks are particularly shown by Fig. 5, and it should be noted that they are each provided with grooves 13 in which the wheels of the carriage 3 run. 14: designates a stop on the outer end of the portion 4 of the lower track.

The tilting portion 5 of the lower track is Specification of Letters Patent.

fulcrumed at 15 and is provided with a laterally extending slot 16, and an outwardly projecting curved member 17 located adjacent said slot 16. This slot and member 17 constitute part of automatically operable means for starting and stopping the motor, as will be hereinafter described.

It .will be understood that after the carriage 3 leaves the tilted elevated track and runs down the lower track, comprising the portions 4 and 5, means must be provided for lifting the carriage from the lower end of portion 5 upwardly to the elevated track. The means shown herein include a spring motor structure 18. The motor structure per 86 forms no part of the present invention, and in the drawings we have shown the same as comprising a spring motor of usual construction including a spring, gears and cooperating pinions. The motor is disposed on an upwardly extending upright 19. On the opposite side of the structure we provide a similar upright 20. p

In addition to the motor, the elevating means for the carriage includes a rotatable frame 21 comprising, as illustrated, two longitudinally extending side bars 22 and a pillrality of cross rods 23. The frame 21 is rotatably mounted on a laterally extending shaft 2%, the shaft having its hearings in the uprights 19 and 20, and connected with the gearing of the motor. Located near one end of the frame 21 we provide inwardly projecting pins 25, said pins being adapted, as the frame 21 rotates, to engage hook shaped arms 26 on the carriage 3. From this construction it will be understood that when the carriage 3 is in the lowermost position on the tilting portion 5 of the lower track, the pins 25 of the rotatable frame will engage the hooked shaped arms 26 of the carriage, thereby raising the carriage from the lowertrack to the elevated track.

For the purpose of preventing theoperation of the motor and therotation of the carriage elevating frame except during the act of lifting the carriage from the lower to the elevated track, We provide automatically operable means including, as illustrated, and as preferred a pivotally mounted vertically extending member 27 having a contact portion 28 designed to be moved in a direction to engage the rotatable member or frame and thereby prevent rotation and to be moved in the opposite direction to allow rotation after a predetermined interval.

The lower portion of the upright member 27 is provided with a laterally extending arm 29, said arm in turn having an upwardly extending member 30 disposed at right angles to the main portion of the arm. Portion 30 is adapted to be entered in the slot 16 of the track portion 5 of the lower track when the said portion 5 is in its untilted position. It will be understood that when the carriage 3 passes the fulcrum point 15, the track portion 5 will be tilted a sufficient distance to free the member 30 from the slot 16, and that in moving to the tilted position the member 17 will bear against the member 30 with sufficient force to cause a slight movement of arm 29 and member 27, thereby moving the portion 28 of member 27 sufiiciently out of the path of travel of the rotatable structure 21, to permit the frame to again rotate and elevate the carriage. It will be understood that after the carriage leaves the track portion 5, this portion will again assume its untilted position and cooperate through slot 16 in looking the member 27 in position to again stop the r0- tative movement of frame 21. By the employment of the automatic stop mechanism, thereby permitting an intermittent motor operation, it will be apparent that the motor will run a much longer time after winding than would be the case did it run continuously.

What we claim is 1. In a mechanical toy, an elevated track, a lower track, a carriage adapted to travel on said tracks, means for raising the can riage from the lower track to the elevated track including a motor, and automatically operable means for stopping and starting the motor.

2. In a mechanical toy, an elevated track, a lower track, a carriage adapted to travel on said tracks, means for raising the carriage from the lower track to the elevated track including a motor and a rotatable member adapted to engage and disengage the carriage, and means coacting with the rotatable member for stopping the motor and the rotatable member.

3. In a mechanical toy, an elevated track, a lower track, a carriage adapted to travel on said tracks, means for raising the carriage from the lower track to the elevated track including a motor and a rotatable member adapted to engage and disengage the carriage, and means coacting with the rotatable member for stopping the motor and the rotatable member, said stopping means including a member arranged to make contact with the rotatable member.

4. In a mechanical toy, an elevated track, a lower track having a tilting portion, a carriage adapted to travel on the tracks, a rotatable member adapted to engage the carriage on the lower track and deposit it on the elevated track, a motor for moving the rotatable member, and means for stopping the movement of the rotatable member at predetermined intervals.

5. In a mechanical toy, an elevated track, a lower track having a tilting portion, a carriage adapted to travel on the tracks, a rotatable member adapted to engage the carriage on the lower track and deposit it on the elevated track, a motor for moving the rotatable member, and means for stopping the movement of the rotatable member at predetermined intervals, said stopping means controlled by the tilting portion of the lower track.

6. In a mechanical toy, an elevated track, a lower track having a tilting portion, a carriage adapted to travel on the tracks, a rotatable member adapted to engage the carriage on the lower track and deposit it on the elevated track, a motor for moving the rotatable member, and means for stopping the movement of the rotatable member at predetermined intervals including a vertically extending pivotally mounted member adapted to be moved into the path of travel of the rotatable member.

7. In a mechanical toy, an elevated track, a lower track having a tilting portion, a carriage adapted to travel on the tracks, a rotatable member adapted to engage the carriage on the lower track and deposit it on the elevated track, a motor for moving the rotatable member, and means for stopping the movement of the rotatable member at predetermined intervals including a vertically extending pivotally mounted member adapted to be moved into the path of travel of the rotatable member, said stopping means controlled by the tilting portion of the lower track.

In testimony whereof we afiix my signatures in presence of two witnesses.
