Be it ltnon'n that FuANnLrN Burma f-lnosnr. a citizen of the United States, and tcm ot Short Hills, in the county of unil #tate ol' New Jersey, have intot erh-iin new and useful improvein )it ry-Gfo-iounds, or" whieh the a specification,

vcmion has reference in general to s ot amusement devices known as Ao-roumls or round-a-lmuts, and rei particularly to improvements in -sr of mounting' passenger carrying` 1.. or cars on the main structure ol urv-go-round and to novel means for u the same.

tretotore it has been customary to conmcrr v-goroumls in the form either of gie rotatable platform` on which are placed passenger carrying devices tired with rotation to the main platform, or else to mount thereon smaller platforms rotatable about centrally located axes.

"ll f improvements in the mounting of the t f. the advantage ot producing' unique and revel sensations on the part of the passenkerin not obtainable in merrygo-rounds as previously constructed.

the accompanying drawings, which 1 a part of this spccication, and in ivrich like nun'ierals are iis-d to represent sante parts throughout all the figurest l illustratori only certain selected moditi-zatinns orf my invention, but l do not wish to limited thereto, as it is obvious that mv invention may be embodied in numerous oth-ci Forms.

in these drawings Figure 1 is a plan View ct 1 trurtion emlanlyino my invention; if is sectional View on the line 1li-1l lo showing thc construction ot' the drivconnertion between the motors and the lilimitlual platitorins; Fig. --lis a detail of mounting ot' oneiot' the platforms or cars mnintf a moditic-.ition in the manner ol z :omitting motion thereto; itin. 5 is a p in vien' of a structure similar to that L Fig. 3 is an enlarged sectional illustrated vin Fig. 5, With a different ratio ot' gears; Figs. 8 and 9 are diagrams illustratinnthe paths through which persons situated at dii'erent points in a car pass durin;r the operation of the .inunda-bout.

Describing the drawings in` detail, the numeral l designates u platform supported by main beams or girders 2 connected near their extremities by stifeners 3. This plat-form is so supported that it may be rotated about its axis. any suitable supportingmcans being used, such :tor instance asvthe shafts 8 journaled in bearings attached to the underpinningl of the main platform and carrying thinned wheels 9 resting on the circular' track 10. The platform may he rotated through one ot the wheels 9 driven by means of a gear 1l, tired to one ot' the shafts 8, which meshes with a pinion 12 carried by the driV- ino; shaft ot' a motor 13.

lpon the main platform are mounted one or more passenger carryingr ears .or platforms t3 which may be provided with seats l and which rotate about movable axes spaced from the axis of rot-ation of the main platform. 1n the preferred t'orm of my invention these cars or platforms are fpretierably mounted ecCent-rically with reference toty their axes of rotation. In Figs. 1, 2 and 3 the cars are shown as supported upon and secured to the upper ends of sleeves 22 journaled upon shafts 5 carried by the supportim.;` platforms -1 which are built upon the members 2 and 3 of the main rotatable plat2 torm. The sleeves 22 and oars 6 carried thereby are rotated from motors 16 mounted on the platforms et through the gearing shown most clearly in Fig. This gearinsr comprises the bevel gear 1l meshing with the drivingl pinion of the motor, and tixed 'to the shaft 5 which it rotates. The shaft carries at its lower extremity a pinion L7-which meshes with the gear 1S on the fountershalt 1t), on the upper end of which is mounted an elliptical gear 20. The latter meshes with and drives' the companion elliptical gear 2l secured tothe sleeve 22. its will be obvious, power-from the motor .lo is thus transmitted through gears 15, 14, 17 and 18 to the shaft 19, necessary speed reduction being obtained through the nears il and From the shaft 1t) rotary motion impartedl to the car i3 through the elliptical gears 2() and 21.

Thus it will be seen that uniform rotation he part of the motor gear 15 will result means for rotatingr said car at a. varying angular velocity.

2. An amusement device comprising a main rotatable structure, and a plurality of passenger carrying cars of substantially circular configuration mounted thereon adapted to rotate about axes eccentric to said cars'.

An amusement device 'comprising a main rotatable structure, a plurality of passenger carrying cars rotatably mounted thereon, and nieansfor rotating the lat-ter at a constantly varying speed.

et. Au amusement 'device` comprising a main rotatable structure, a passenger carrying car mounted thereon and constructed to rotate about an axis eccentric to said car, and means for rotating said passenger carrying carat a varyingangular velocity.

5. An amusement device comprising a main rotatable structure, a plurality7 of passenger carrying cars mounted thereon and constructed to rotate about axes eccentric to said cars, and means for rotating each passenger carrying car at a constantly varying' angular velocit-y independently of the other cars and of the main structure.

6. An amusement device comprising` a main rotatable structure, a passenger Jarrying,r car rotatably mounted thereon, and means including elliptical gears for rotating the cars.

7. An amusement device comprising a main rotatable structure, a passenger carrying' cai' rotatably mounted thereon, and

,means for rotating said car at a variable velocity, said means comprising a power de-.

vice operating at a substantially constant speed 'and variable speed gearing for transmitting power from said power device to said car.

8. in an amusement device a main rota.- table struct-ure, a passenger carrying car rotatably mounted thereon, a motor carried by the said main structure, and means includingr elliptical gears for imparting rotation from said motor to the said passen ger carrying car.

9. In an amusement device, a. main rota-- table structure, a plurality of passenger carrying cars rotatably mounted thereon, and a plurality of motors mounted onsaid main structure, one for rotating each of said ears.

10. An amusement device` including; a main rotatable structure, a passenger carrying carl rotatably mounted thereon means for rotating said car, said means ing alternately to accelerate and retard rotary motion of the car.

l1. In an amusement device, a motor, a main rotatable structure, a passenger carry actthe

'ing' car rotatably mounted thereon, a ,uiaiir shaft coincident with the axis of rotation ot the said car and adapted to be rotated by said motor, a countershaft adjacent to said main shaft and parallel therewith, means for transmittingmotion from the main shaft to the countershaft, a sleeve on said main shaft rigidly attached to said passenger carrying structure, and driving means between said sleeve and countershar't;

12. In an amusement device, a. motor, a main rotatable structure, a. passenger carryinny car rotatably mounted thereon, a main shaft coincident with the axis of rotation of the said car and adapted to be rotated by said motor, a countershatt adjacent to said main shaft and parallel therewith, means` for transmitting' motion from the main sha t to the countershaft, a sleeve on said main shaft rig-idly attached to said passenger carrying structure, and an cliiptical gear on said countershat't and a c ;ries: u= dit. elliptical gear jon said sleeve irreshing' with the elliptical gear on said counter-shaft.
