- invention,.such `as will enable others skilled in the` art to which it appertains to malte and use the same. f f y.

This invention relates to an in'iproved merry-go-round which is especially, butnot necessarily designed foruse by children, the

same being such in construction that itis manually operated by oneof the occupants either by a hand rope 'or lever arranged in convenient reach of the operator.

The principal object of the invention is to generally improve upon devices of this classi by providingone ofextrenie simplicity andv dura-bility which is well balanced and so constructed that it is very easy for a single child to propel the same.

Another object of the invention is to provide a. pleasure device of this classwhich embodies a novel arrangement of levers and links for imparting a rather speedy vrotation to the seat carrier withoutrequiring theoperator to exert himself tol such a degree as to become readily tired.

Another object of the invention is to provide a merry-go-roundy which embodies a standard with a. rotary carrier mounted on the upper end thereof, this' carrier embodying radial arms which support the individual seats, these arms ,being formedv of light weight metal but being braced by novel mea-iis which does' notinterfere `with free-rotation of the carrier and insures strength and durability. l

A. further object of the invention is to providev a structure wherein the various parts may be easily and readily detached from onel another to enable repairs Vto be easily made'.

Other objects and advantages of the -invention will be appa-rent during thecourse of the following description.

ln the accompanying drawings forming :i part of this specification and which like numerals are employed to designate like parts throughout the same: Figure l is a. perspective view of a merrygo-round constructed this invention.

yFigure 2 is ya top vplanview thereof.

Figure is a sectional view, with parts in in accordancev with elevation, showing the detailsvof construe,

tion more clearly.

Referring `to the drawings, theviiuineral 1 designatesa'base from lwhich a standard 2 rises, this standard beingformed in litsA up# perfendfwith a socket 3. Removablyar ranged in this socketis a' shaft a which f extends above the upper. end of the standard and has a ratchet 5, keyed or otherwisepei trice.

inanently secured lthereto vto :render `it sta` tionary. To prevent rotation of theshaft., aset-sci'ew` 6 lis employed.l .By carefully examining the sectional view] appearing 'in specially constructed so as :to accommodate ball bearings 7 which are interposed betweenl Fig. 3, it will be seen that the ratchet 5 is which is rotatably mounted onthe shaft 4 and is held-in place by a nutlO. l/Vith this arrangement, it ywill be seen .that the entire carrier` can be removed whenever necessary orY desired. `The carrier inladdition to einbodying this spideryincludes a plurality of radial seat-supporting armsl 11 which are bolted or otherwise secured to the outer ends of the spider arms-as indicated at 12. before set forth, these larms are constructed as light `in ,weight asis possible to insure strengthv yet not to interfere ,with thefiee rotationl of the carrier. However, to `insure against .any breakage which may occur and to prevent vthe arms vfrom bending, I employ a. number of diagonal braces 13`whicliare secured at their upper Vends to the carrier arms andare attachedat their lower ends to a collar 14C vwhich surrounds the standard. below the aforesaid set-screw 6. An adjustable `stop 15 c'o-operates with 'this As l collar 1l to prevent the saine from slidingy down on the standard and permits it to be elevated to render the carrier arms horithe strain to whichv they are subjected.l In

order to insure free rot-ation of the carrier -v and bracing means. ball bearings 16. are in-V upper end of the standard and said ratchet and this arm serves to carry a paivl 18 which is designed for co-operation with the teeth of the ratchet. A flat spring 19 serves to hold the dog in engagement with the ratchet.

A plurality of seats 20 are supported from the outer ends of the aforesaid carrier arms by means of vertically disposed spaced side bars 21 and at least one of these seats is designed to be occupied by the operator, that is, the person Who constitutes the poiver for manually actuating the device. Of course, if found advisable, one or more of the remaining seats could be equipped with operatingmeans to enable the Work to be equally divided among the several occupants. For the sake of clearness, a single operating structure has been shown. By referring to the seat equipped with this operatingl means, it *will be seen that said means comprises a lever 22 which is pivoted intermediate its ends on the inner vertical side bar 21 of the seat under consideration. At its lower end, this lever is equipped with a horizontal handle 3 designed to be grasped by the operator 2st. A second and L-shaped lever is pivoted at 26 on the intermediate portion of the adjacent carrier arm and a link 27 serves as a connection betvveen the tivo levers. A second and shorter link 2S is pivot-ally connected to the short arm of the L-shaped lever and to the dog-carrying; member 17 and it is obvious that by grasping the handle and exertinga pull towarl the seat, a rotary motion vvill be imparted to the carrier and seat. At. ivill be found convenient to operate the device by means of a rope in some instances and to permit this endto be accomplished, l employ a bell-crank 29 and dispose this, by means of brackets 30 between the verticalside bars of the yoperato1"s seat, and connect this bell-crank lWith the aforesaid L-shaned lever 25 through the medium of a link 31. A rope 32 is connected to the remaining arm of this bellcrank and depends into convenient reach of the operator. If desired, the handle 23 may be such that it can be swung; out of the Way of the operator ivhen the rope is being used, any suitable construct-ion being employed for enabling this result to be obtained. For the purpose of maintaining' the parts in the position shoivn in the drawings, l make use of a relatively large coiled spring 33 which is connected with one of the elements of the operating means and the succeeding` carrying arm.

The operation of the device is as follows: Assuming that the operator is in the seat on which the operating means is arranged and further assuming that the parts are in the position shown in the drawings, it will be seen that When the operator grasps the handle 23 and exerts a pull toward himself, the

links and levers Will momentarily be locked and act as a unit to exert a push against the ratchet. inasmuch as the lastnamed element is fixed, it is obvious'that the rotary head or carrier will be moved in the direction of the arrow A. During this motion, the 'dog will ride over the ratchet teeth and the operating` means being connected with the carrier, it will be moved around With the latter so that When the operator desires to obtain another pull, this can be done because the parts are in a convenient position to permit it. The coiled spring referred to serves to automatically return the parts with which it co-acts to their normal positions. llie operation will be exactly the saine if the pull rope is used.

By carefully considering the description in connection With the drawings, persons familiar with devices `of this class `vill doubtless be able to obtain a clear understanding of the invention. Therefore, a vmore lengthy and detailed description is deemed unnecessary.

Since probably the best results may be obtained with the construction and arrangement herein shown and described, this is taken as the preferred embodiment of the invention. However, I Wish it to be understood that minor changes coming, Within the scope of the invention as claimed may be resorted to if desired, such for instance as the omission of the base and the setting of the standard into the ground.
