Application .iiledDecember 23, 1825. `Serial No. 77,339.

'This invention is directed to an amusementdev-ice, in which a series of passenger Vcarrying cars are movable fronianinoperative orloadingposition, vat which the pasn sengcrs may readily enter or leave the cars, to an .elevated position,with the cars in `the latter position adapted to revolve as a unit .about an. axis,-to. provide .the thrillingride .for which the device isdesigned.

.The `Construction as' a whole Isimulates in .its general `structure `a gigantic Iumbrella, with therodformingthe axis andthe pasi senger carrying. cars supported at the ends of 4elements simulating theribs oftheuinbrella, cooperating elements simulating the umbrellastretchers being connected to the ribsand toa member simulating the runner -of the u1nbrella,.by.which the ribs and thereby the cars may bemoved from a lowered, or

umbrella closed position, to disposethe cars convenient to a platform to permit thepassengers to enter or leave the cars, the actuating apparatus initially raising ythe runner element and thereby the ribsto elevate the cars above-.the ground andat the same time moving .them outwardly, following which the structure as an entiretyis revolved about the ,axis or umbrella rod.

TheEinvention.comprehends a simple elii- -cient means for operating the parts so that the cars may be readily raised-orlowered vandzrevolved about the axis ofthe device after being elevated.

Theinvention is illustrated. in the accompanying drawings, inwhich: p

Fig. .1 isa view in elevationiof the improved ainusementdevice. Fig. 2 isa section on line 2-,2 of 1.

Fig. 8 is. aY vertical section of the operating tor. rIhe upper portion of the elevator is of cylindrical form with the wall of suflicient thickness to sustain the weight of they parts, while the lowerportion of such elevator is exteriorly formed to provide a worm thread 5. The lower end of the elevator isiprovided with or has secured thereto a control member, inthe form of a ring-like eXtension below the worin thread, with such ringlilre extension provided with a radiating lug 7, the purpose of which will later appear. A crown head 8 isV rotatably supported upon the upper end of shaft .1, this crown head being formed to provide cooperating pairs of radiating arms 9 between which lis pivotally supported bars 10, simulating the ribsV of the umbrella-like structure, andhereim after termed the rib bars. -These rib bars carryr at their outer or V'free ends` any convenient form or type of carriage or car 11-for the reception of passengers, the particular construction of this car being without importaiice in the prescntinvention.

rlhe runner sleeve- 3 is formed atitsjuncture with the wornrthread portion, with an ,annular ringlike extension 12 having radiating` ,arms in pairs at 13 to pivotally receive and support the lower ends of bars 14, the outer or free ends of which are pivotally connected at 15 to the-rib bars 10, these'bars 14 serving a function similar to that of and beinghereinafter termed stretcher bars.

Therunner sleeve 3 and the crown head 8 are held against relative rotative movement Vbut permitted independent relative sliding liovement through the `medium of-rods 16, secured -in the crown head ,and ypassing through sleevelike guides'l formed on-the runner sleeve. 3. Thus the sleeve may-move lup and down relative to the crown head,but

cannot rotate independentlvof such head. The crown head is formed with diametrically opposed recesses 18 and the runner sleeve 3 is formed with correspondingpro- Yjections 19, adapted .when Y the runner v,sleeve has reached.itsupper limit ofvmovement to interlock the sleeve and crown-headzto insure. a positive rotation of the crown headin the similar operation of the runner sleeve.

Aloading platform 2O is arranged in line with the juncture between the plain and threaded portion of the runner sleeve when this element is in llowered position. rIhis ,platform `constitutes tlielimit of .lowefad movement or cliccare 'd provides a means array y enter er' .leave by which the .pas

the cars. Of course the platform may be elevated above the ground surface to receive the other parts below the platform, or such platform may constitute the ground surface and the relatively lower parts be arranged 1n a pit. Arranged in line with the platformQO is a main `gear 21 formed for cooperation through a threaded interior 22 with the threaded portion 5 of the runner sleeve. This gear 2l is operated through an intermediate gear 23 by a shaft 2:4 actuated from a suitable source of power through appropriate shafts in gearing indicated at guide member 2G is arranged lengthwise the threaded portion of the runner sleeve, this guide member extending from the base 2 to the platfori'n 20. The guide member is in the form of a vertically channeled bar 2T, with the channel of a size to slidably receive the lug 7 of the control member 6. At an appropriate point near the upper end, walls of the guide member are cut out at 28 to permit the lug T to move laterally7 free of the guide member. Pivotally supported upon the guide meniber is a latch 29, the operative portion of which is adapted, when the latch is in actuated position, to close the opening 252 in one wall of the guide member, the position of the latch being controlled through an operating cable or rod 30. Chains 3l may be used to connect the rib bars 10 to the crown head 8, serving to prevent any undue spreading of the rib bars in the movement of the parts after the carriages have been elevated. Assuming the parts in normal or inoperated positions, as indicated in F Il, it ill be noted that the runner sleeve 3 is at its lowest limit of movement, the passenger cars l1 are resting on or innncdiately adjacent the platform-20, the lug T is in the lower end of the guide Q6, nd in that simulation heretofore referred to, the umbrella structure may be said to be closed. Then applying power, the gear 2l driven, but the runner sleeve cannot rotate, incident to the tit-:ed path of travel of the lug 7 in the guide 26, the operation of the gear 2l will, through the worm thread formation 5 of the runner sleeve, move said sleeve upwardly. This operation tends to raise the rib bars l0, and thereby the passer r cars ll, through pressure on said rib baiby the stretcher bars 14, this movement continuing until the carriages or cars nave reached the .fully elevated position and the projections 19 on the runner sleeve 3 are interloclred in the recesses 18 in the crown head 8. As this interlocking cooperation talres place, the lug 7 has reached the cut out 28 of the guide 26, and therefore further operation of the gear 2l will cause the runner sleeve, crown head, and passenger cars carried thereby to revolve about the shaft l as a center. In returning the cars to the platform to discharge the passengers, thel driving force of the gear 2l is gradually reduced and as the cars come to rest, the latch 29 is moved to close the opening 28 in the wall of the guide 2G. rEhe power is reversed, and as the guide reaches the stop position in rotation, the rotative movement of the runner sleeve is interrupted, and the further operation of the gear will cause the sleeve to move downward by feeding the same through the worm thread cooperation. This lowers the ruimer sleeve, stretcher' bars, rib bars, and carriages, the movement being continued. until all parts arereturned to normal position.

It is intended that the simulation of the umbrella be further carried out by providing the rib bars with suitable covering as a whole in the form of any canopy construction, to simulate the umbrella covering. This canopy is not illustrated as it may or may not be used, and if illustrated, would tend to confuse the detail.

The structure as a whole provides a simple form of amusement device in which passengers maybe safely raised to considerable heights and caused to follow a circular path of travel at that height, thereby imparting a decided thrill and amusement to the passonger.
