MECHANICAL TOY.

SPECIFICATION forming part of Letters Patent N o. 369,623, dated September 6, 1887.

Application iiled February 2l, 1887. Serial No. 228,354.

To all whom it may concern:

Be it known that We, FRANCIS J. TOTTEN and ALBERT S. TorrEN, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Mechanical Toys; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a vertical central section of our improved toy. Fig. 2 is a plan view thereof, the top board of the toy being partly broken away to illustrate the clock-work mechanism. Fig. 3 is a side view of a part. Fig. 4 is a sectional view of a modified form of a part.

Like symbols of reference indicate like parts in each figure of the drawings.

In the drawings, 2 represents a box or case of cylindrical form. The top of the box is covered, there being an annular rim or coverstrip, 3, around the edge of the box, and a central circular cover, 4, somewhat separated from the ring 3, so as to leave an intervening circular slot, 5. The parts 3 and 4 are held together by arches 6, which span the slot 5. Inside the box 2 is clock-work mechanism comprising a spring, 7, a key-arbor, 8, and a vertical shaft, 9, which is driven by the spring. From the shaft 9 projects a horizontal arm, 10. A suitable toy, 11, mounted on Wheels, is set on a circular track on top ofthe box 2, and is provided with a vertical stern, I2, which extends down through the slot 5 into the interior of the box. When the shaft 9 is driven by clock-work, it causes the radial arm l0 to move around in the box, and by engaging the rod 12 causes the toy-cars l1 to travel around on their track beneath the arches.

We are aware that we are not the first to invent a toy wherein a rotary clock-workdriven arm drives a vehicle around on a cir cular track, nor are we the first 4to use the arches 6, which serve to connect the parts of the top rigidly together without interfering with the slot. 1

Ourinvention consists of mechanism whereby the motion of the toy can be retarded or checked at will. Connected with the shaft 9 so by suitable gear-wheels is a vertical shaft, 13,

on which is a small drum,'14. A flexible band, 15, is secured at one end to a post 16, and after enwrapping or partially enwrapping the drum 14 is attached to the free end of a lever, 17, which is fulcrumed at a point, 18. At the point of attachment with the band 15 the lever 17 is bent and extends to the outside of the box 2 through an elongated slot, 19. On the outside of the box is an upright lever, 20, which is pivoted at 21, and at itslower end is connected with the lever I7. By turning the lever 20 on its pivot 2l the lever 17 is turned on its pivot 18, and in this way the band l5 may be caused to exert a pressure of a greater or less degree upon the drum 14. By exerting a greater pressure on the drum the movement of the clock-work may be stopped altogether, and by a less pressure it may be retarded. In order to provide means for enabling the lever 20 to be locked at any position when the desired tension of the band is obtained, we provide the lever with a rack or quadrant, 22, making in it a series of holes. A longitudinally movable latch, 23, is arranged on the side of the lever, and is movable to engage any one of the holes of the quadrant when the lever 20 is opposite thereto.

In Fig. 4 we show a modified form of device for braking the drum 14. I'Iere the band 15 is attached to a screw-rod, 24, which extends through ascrew-threaded bushing, 25, in the side of the box 2. By screwing the rod 24 in or out the tension of the band ou the drum may be diminished or increased.

We claim- 1. The combination of a movable toy mounted on a circular track, stationary clockwork, a rotary arm driven by the clock-work anddriving the toy, and braking mechanism bearing on the clock-work for adjustably retarding the motion thereof, substantially as and for the purposes described.

2. The combination of a movable toy mounted on a circular track, clock-work mechanism ilnpelling the toy, the drum 14, connected with the clock-work, and the brakeband 15, enwrapping the drum, substantially as and for the purposes described.
