@NFEED STATES PATENT WILLIAM S. TQTHILL, OF CHICAGO, ILLINOIS.

MEBRY-GD-ROUND.

Application filed March 5, 1914..

To all whom it may concern:

Be it known that 1, WILLIAM S. To'rHiLL, a citizen of the United States, residing at Chicago, in the county of Cook, in the State of Illinois, have invented certain new and useful Improvements in Merry-Go-Rounds, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to merry-go-rounds and particularly to that type of merry-gorounds shown in the United States patent granted to me on September 16, 1918, No. 1,073,449.

It is one of the objects of my invention to provide new and improved means for securing the inner ends of the radially-positioned beams of the platform of the device whereby the beams may be held securely in place and whereby they may be tightened from time to time as the necessity may arise.

It is another object of my invention to provide new and improved means for holding the said radially-positioned beams of the platform in proper position relative to each other whereby the platform is prevented from sagging down at its outer edge.

It is another object of my invention to provide new and improved means for securing the platform firmly in position relative to the supporting member whereby the platform is held constantly in the proper plane and is prevented from rocking relative to the support.

t' is another object of my invention to provide a new and improved means for ro-= tating the platform.

It is another object of my invention to provide a new and improved spring support for the horses or other animals provided on the platform.

It is another object of my invention to improve devices of this type in sundry details hereinafter pointed out.

The preferred means by which I have accomplished these objects are illustrated in the accompanying drawings and are hereinafter specifically described.

That which I believe to be new is set forth in the claims.

In the drawings,-Figure 1 is a top View of my improved merry-go-round, broken away at one side and having the platform broken away at the other side to better show the means for holding the platform beams Specification of Letters Patent.

in proper position relative to the standard; Fig. 2 is a central vertical section through the device taken on line 22 of Fig. 1; Fig. 3 is a side view of the cap which encircles the standard immediately above the bearing of the platform; Fig. l is a View illustrating the construction of the spring by which the horses are supported upon the platform; Fig. 5 is a detail of the spider in which the inner ends of the platform beams are mounted; and Fig. 6 is a detail of one of the devices for tightening the rods, which extend through the platform beams for holding said beams in proper position relative to the standard.

Referring to the several figures of the drawings in which corresponding parts are indicated by the same reference characters, I

10 indicates a base of any suitable form, having mounted thereon a plate 11 from which rises a standard 12. Surrounding the standard 12 and spaced away therefrom is a bearing-ring in the form of a spider provided with a plurality of radially-disposed sockets for the platform beams 14, the inner ends of which beams abut against the standard 12. As best shown in Fig. 2 each of the beams 14 is provided with a plate 15 underneath its inner end, against which plates the set-screws 16 carried by the spider 13 are adapted to bear. As will be readily understood, the outer ends of the beams 14 are adapted to be raised relative to the spider 13 by means of the set-screws 16, whereby the beams 14 can be adusted relative to each other to keep the platform in proper alinement.

1718 indicate steel rings mounted upon the plate 11 and the spider 13, respectively, between which steel rings are mounted a plurality of balls 19 held in proper relation to each other by a spacing device 20.

21 indicates a cap mounted upon the standard 12, said cap comprising a collar 22 secured in position by a pin 23 passing through suitable holes through the collar and through the standard 12 and by set screws 24: carried by said collar at opposite sides bearing on said standard. Said cap also comprises a pressure-plate 25 adjustably connected to the cap by bolts 26.

27 indicates set-screws mounted in aflange of the collar 22 bearing against the pressureplate 25. As will be readily understood, by loosening the nuts on the bolts 26 and {clip 39 to the spring 37- whole, very efi'ectually.

held infproperrelationto each other by a spacing device 31.

With the frame comprising the spider 13 and the beams 14 in position upon the standard 12 between the two sets of anti-friction devices, by a proper adjustment ofthe setscrews 27 the'play of the frame or platform between the cap 21 and the plate 11 can be limited as desired, preventing the frame from canting relative to the stand ard, thus maintaining the parts in proper working position. 7

The 'means for adjustingthe beams 1 relative to each other for tightening the frame about the standard when it becomes loose through any means consists of an adjustable rod 32 formed in sections joined together by couplings 33. As vill be understood from an inspection of Fig. G-the coupling 33 comprises two sleeves joined together along their adjacent edges, the sections of the rod 32 being screw-threaded at their ends whereby the length of the rod 32 may be varied as desired. As shown in Figs. 1 and 2 the rod 32 passes through suitable holes through the beams 14 at a suitable distance from the standard '12. When the ends of the beams 14 becomeworn or the platform otherwise becomes loosened inits joints,0r relative to the standard 12, the rod 32 may be tightened by turning the nuts on the sections of the rod. It has been found that in this manner the beams 14: can be moved a short distance inward when required, tightening up the platform as a 3435 indicate seats made in simulation of chariots secured upon the'pl'atform of the merry-go-round, and36 indicates a hobby-horse secured bya suitablespring device upon said platform. As best shown in Figfl, the spring support for the hobby-horse comprises a curved'flat springf37 securedflat one end to the horseand at the other end'to the base or platform, and a second curvedfiat spring 38 positioned inside the curve of the spring 37, the spring 38 being also secured to the base or platform at its lower end. In the construction shown the spring '38 is secured at its upper end by means of a 40 indicates a cross-head fixed upon the upper end of the standard 12 provided with handles 41 risingfrom its ends. Aswill -be readily understood a boy standing upon the platform of the device can graspthe handles 41 of the cross-head l0 and by an action as if to turn the cross-head" 40 can to secure by Letters Patent, is
