a desired speed before he transfers to the vertical track. p

With such apparatus, for an adequate exhibition to be afforded, it is necessary for the spectators to mount and stand upon a staging in order to look downinto the hollowcylinder, said staging being costly and diflicult to transport anderect, v p The present invention has for its object to provide an apparatus of the type to which the invention relates, but upon which a much more thrilling performance can be given, and which moreover will permit thejperformance to be viewed from the ground,'thus enabling if required the staging to be entirely dispensed'with. i j 7 According to the present invention, a vertical walled track, whichmay be collapsible, resembling an open-ended cylinder is provided, which may becircular, oval or of other appropriate shape seen inplan, This is pref-.

erably made up from a suitable frameworkand from well spac'ed slats, so thatthe wall constituted thereby can readily be seen through. p I

The vertical walled track thus constituted is mounted in gimbals I or on trunnions or shafts insuitably supported bearings to sustainthe structure a desired distance from the ground, and hand or power actuatedgear is provided to enable the track structure tovbe rotated around the aXis-of said gimbals, trunnions or the like Means are provided to' enable a motor-cyattained the track, it is adapted to betur'ned cli st upon a machine to enterand ridear'oundthe said vertical walled track when it is in What may be termed the usual horizontal plane, and after the rider and machine have around the horizontal axis so that it reaches what may be termed a vertical plane, when the rider and the machine whilst riding round the track'also loop the loop a de sired number of times, before the 'tr-ack'is again brought to the horizontal position and the rider and machine are again able to transfer from the "vertical walled track to the starting and stopping means; The preferred meansfo'r enabling the rider and machine to be transferred to the vertical walled track may resemble an a-pparatus such as already known, but adapted to be moved vertically through a desired distancerela tively to the vertical walled track mounted in the gimbals or the like. For example, mounted below the revoluble track-structure is a shallow basin-like track of closedor open slat construction which is designed normally to occupy a low position, for instance to rest on o-rnear the floor, and means arepro'vided to raise this-base-like track upwards to meet or ioin-with the revoluble main track,

so that the same can become the base of the latter. The raising and lowering may be effected through suitableapparatus and may be guided asdesired. V

In order that the invention may be better understood, it will now be described with a reference to'the accompanying drawings in 9 which;

I 1 shows somewhatdiagrammatically in sectional elevation preferred apparatus constructed according to the invention. i

Fig. 2 shows a side elevation of the 'apparatusshown in Fig. 1. V a i F1gs.,3;4' and 5 show d agrammatic eleva-:

tional views, somewhat in perspective, "illusg trating the method of us ng the: apparatus accordlng to'the inventions r I formed from spaced slats such as indicated at 11, it being understood that the slats extendthe whole of the way around. The hollow cylindrical structure 10 forms a vertical walled. track and may haveany required di- 'mensionsl In one. preferred form, however,

the said track may have a diameter'of about 15 feet and an axial length of about 8 feet. One of the stub shafts 9=carries a worm wheel 12 with which meshes a worm 13, the shaft of which is carried by suitable bearings and has fixed thereto a sprocket wheel .14 whlch.

is connected .by a chain 15' with another sprocket 1:6- carriedby a suitable shaft adapted to be actuatedfrom a handle; 1.7. In this manner by turning the handle 17, the verti cal walled track 10 can be turned on the stub shafts 9 sothat it. occupies for example the full line position. shown in Fig. 2, or the dotted. line position; v

1 Below the vertical walled track lO-ls'looated? a shallow basin-like structure comprising F a: framework carrying, a vertical walled trackJ18 and a lower slope 19 and horizontal. platform 20; The vertical walled tracklS and the slope 19 may beformed from slat .or similar constructioni-f desired and the whole is carried bylug-like' members 21inclnding travelling nuts 22 carried in guideways by the members-23 of thestandards 6. Between themembers 213' of each of the standards is mounted in bearings a vertical screw 27, so1th'at the said screw can turn but can not. move axially; Each screw engages with a correspondingnut 22 and at its lower end has located thereon a bevel wheel 28 which meshes with: a'bevel pinion 29 carried by a horizontal shaft 30 supported in bearings by the" framework 7. One end of the shaft 30 carriesasprocket wheel 31- connected to another sprocket *wheel'32' bya chain 33, the shaft. of the sprocket wheel 32 having an actuating handle; 34. mounted thereon. 7

By this-'means, upon the rotation of the handle 34 the two screws- .27' (only one of which istshownin the drawings) are rotated 1 on theiraxes,v and this, causes the nuts 22 to move axially andraise or lower the shall ow basin-like structure, If it is in the position shown: in. Figs land 2,. it may be 'raise'dito contact with the lower end of the vertical walled track. 10, and when in this-position can be-l-owered to the position shownin-sFigs. 1 and2. .For the purposes of utilizing the apparatusytherider upon a .motor cycle enters the basin'eli-ke lower structure as indicated in the v diagrammatic view, Fig.3, and this basins like structure is then raised until it occupies the position shown in Fig. 4. The rider then starts the machine and runs around the slope 19 thereon, until a desired speed is attained, when the rider transfers to the short vertical track 10. This is the position'of the rider shown in Fig. 4.

The lower basin-like track structure is now lowered by the handle 34: and the main vertical walled track is turned by the handle 17 to occupy. the dotted'position shown in Fig. 2,. during. the whole of the time. the rider on the machine running. around the vertical tween the slats of the tracks.

YVhilst therider still circlingtheltrack. 1O is again turned to the horizo-ntalposition, and the. lowergstructure. raised to. join therewith, permitting the rider to transfer.

to the lower structure, thenceto the slope 1-9.

and to .come to rest iii-the ordinary way,

It is of course obviousthatthe rider. might start up and ridev around thelower slope. l9 and the lower. track 18 when. it. was in the lower position and: while so riding. round, beraised before. transferring. to the. track. 1.0..v

Although generally speaking a. slatted structure is desirable for the tracks, some cases other open-work structurev may be adopted, such for example as. a. track made walled track 10. When the vertical position from. suitably supported. expanded metal)...-

perforated metal or otherwise.

Moreover, although. it isfpreferable to utilize the means indicated for enablingtherider andmachine tov be transferred to andfrom the vertical walled. track, in somecases other means may be adopted. For example if de sired, one open end of the. vertical walled track itself maybe provided with a sloping portion and. a closed. centre, and means. provided by which the rider and machine can be located at this end, which preferably comes lowermost. Forthis purposeif desired, the vertical walled track itself may be madeto be raised or lowered, or else av ladder or other elevatingmeans may be provided by which therider and machine canbe'located in position. With this modification, afterthe desired speed isattained on the. slopeportion, the rider willtransfer tov thev vertical wall and then the whole device turned uponthe gimbals, stubshafts or the like- The'invention is not limited to the precise.
