Application filed June 15, 1909. Serial No. 502,401.

and the primary object of the invention is to provide a device of this character having an inner and an outer rotatable platform, arrangements being made whereby the said platforms may be caused to move at dilfercut rates of speed, thereby producing a racing elfect to the toy animals upon the platforms.

With the above and other objects in view, which will appear as the description progresses, the invention resides in the novel construction and arrangement of parts hereinafter fully described and claimed.

In the accompanying drawings there has been illustrated a simple and preferred em- I bodiment of the invention and in which,

Figure 1 is a top plan view of the device with parts broken away to more clearly illustrate the details of the same. Fig. 2 is an enlarged sectional view upon the line 22 of Fig. 3 is a similar sectional view upon the line of Fig. 1. Fig. at is an enlarged detail view of the operating pulleys, the upper pulley being shown in section.

In the accompanying drawings the numeral l designates the central post of the device. This post 1 has its lower portion buried a suitable distance in the ground as illustrated by the dotted lines in Fig. 3 of the drawings. The post 1 is also provided with a suitable anchor block 2 which is adapted to rest upon the ground and to effectively support the post 1 in an upright position. The post 1 is provided with a rigidly secured ring 3 having its lower extremity provided with an annular offset portion 4 and this offset is adapted to serve as a bearing for an L-shaped ring 5. This L-shaped ring or member 5 is provided with a plurality of radiating arms 6 and these arms are adapted to support the inner platform 7 of the device. The outer extremities of the arms 6 are connected together through the medium of a plurality of brace members 7 and 8. These members 7 and 8 are spaced a suitable distance apart and are each provided with bearings 9 for the reception of a shaft 10 carrying a wheel 11. The device is also provided with an annular bearing 12 upon which the wheels 11 are adapted'to travel. The bearing 12 illustrated in the present instance comprises suitable bloclrs 13, the upper one of said blocks having its top recessed and adapted for the reception of a metallic bearing ring let.

Positioned upon the outer brace member 7 and upon the tops of the radiating arms 6 is an annular track or rail 15. This rail has its outer face concaved as at 16, to provide a recess for the operating cable 17.

The numeral 18 designates the outer platformof the device. This platform is provided with a plurality of spaced depending legs or sections 19, between which is positioned a plurality of axle members 20, each carrying a flange wheel 21 which is adapted to rest upon the rail 15. The upper portion of the annular platform 18 is provided with a grooved plate 22 and the groove provided by this plate is adapted for the reception of a second operating cable 23.

Positioned a suitable distance away from the merry go round proper is a vertical shaft 24. This shaft 24: is provided with grooved wheels 25 and 26. These wheels 25 and 26 are of different diameters and are adapted for the reception of the operating cables 17 and 23. The shaft 2 1 is mounted in suitable bearings, not shown, and is provided with suitable pulley 27 adapted for the reception of a belt 28, connected with an engine or any other suitable source of power. The grooved wheel 25 is rigidly secured to the shaft 2 1, while the grooved wheel 26 is removably attached thereto. By reference to Fig. 4 of the drawings it will be noted that the shaft 24 is provided with an annular collar 29, upon which the hub 30 of the pulley 26 normally rests. This hub 30 has its upper portion provided with a cut away portion or pocket 31, which has its annular wall preferably inclined as shown in the said Fig. 41 of the drawings.

The numeral 32 designates a sliding clutch member of a suitable frusto-conical form which is adapted to ride upon the axle 24 and to engage with the wall of the pocket 31 provided upon the hub 30 of the pulley 26. This clutch member 31 is provided with a suitable spline working within a vertical groove provided upon the shaft 24 and the clutch 32 has its upper extremity provided with an annular recess 33 which is adapted for the reception of a bifurcated extension 8% provided upon a suitable lever 35. This lever 85 is pivoted as at 36 to a suitable support and itwill be noted that by exerting pressure upon the outward face of the said lever the clutch 32 may be raised out of the pocket 31 or may be snugly positioned therein.

It is to be understood that the clutch member 32 may be, if desired, entirely removed from the shaft 2st to allow for a second wheel 25 of a different diameter to be positioned upon the said shaft when the clutch is repositioned and engaged by the lever 35 as previously described.

From the above description, taken in connection with the accompanying drawings, it will be noted that by operating the clutch meml er 32, the outer platform 18 may be practically immovable, while the inner platform 7 revolves at a predetermined speed and that by forcing the clutch into engagement with the pulley 26, the said pulley will be caused to revolve and the dummy animals upon both of the platforms will produce a racing effect.

Having thus fully described the invention what is claimed as new is:

l. A post, radiating arms upon the post, a platform rigidly secured upon the arms, brace members between the radiating arms, bearings upon the brace members, a shaft for the bearings, a wheel upon the shaft, a track for the wheel, a rail upon the radiating arms, said rail having its outer face concaved, a second platform, a concaved ring upon the second platform, wheels upon the second platform engaging the rail of the radiating arms, an operating shaft, a pair of grooved pulleys of different sizes upon the operating shaft, an endless cable for each of the pulleys, one of said cables engaging the grooved ring of the secondary platform, and the other cable engaging the concaved face of the track provided upon the radiating arms.

2. A central post, a ring having a flange upon the post, an L-shaped circular member upon the offset portion of the ring, said L- shaped member being provided with a plurality of radiating arms, a platform secured to the radiating arms, spaced bracing members between the radiating arms, said members being each provided with bearings, a shaft for the bearings, a wheel upon the shaft, a circular track for the wheel, a circular rail upon the outer brace members and the radiating arms, said rail having its outer face concaved, a secondary platform, said secondary platform having a grooved ring extending around its outer face, wheels carried by said secondary platform and adapted to engage with the rail, an operating shaft, means for rotating the shaft, a grooved pulley rigidly secured to the shaft, a cable for this pulley engaging the concaved rail of the merry go round, a collar upon the shaft, a second grooved pulley of a different diameter from the first pulley removably positioned on the shaft and resting upon the offset portion thereof, the wheel of this pulley having one of its faces provided with an inclined bore, a clutch member of a frusto conical formation slidably mounted upon the shaft, and a lever connected with the clutch member to force the clutch into or out of engagement with the pocket of the pulley.

In testimony whereof we affix our signatures in presence of two witnesses.
