.9 Claims. (01. 272-43) This invention relates to amusement devices used in fairs, carnivals, etc.,' and more particularly to that type ofamusement devices which a number of carriages are rotated around acome mon center to provide amusement for passengers in the carriages. 1

A particular object of this invention is to provide a novel mechanism by which a number of carriages are simultaneously subjected to a novel series of motions while said carriages are traveling around a common center. 1

A further object of this invention is to provide a mechanism of this character which shall besimple but substantial in design and safe in operation.

Other objects of the invention are shown in the specification and drawings in which Fig. 1 is a plan view of my amusementdevice.

Fig. 2 is a partial plan view of same, with the rotating platform and carriage mechanism re- 29 moved.

Fig. 3 is a vertical sectional view of my amuse ment deviceon line 3-3 of Fig. 1; v

Fig. 4 is a. vertical sectionalview of a swivel bearing on line 44 of Fig. 5.

Fig. 5 :is a plan view of the. swivel bearing ofFig.4. I

Fig. 6 is a plan view of a pivot bearing.

Fig. ,7 is a vertical sectional viewof saidpivot bearing on line '7-'7 of Fig. 6.

130 Fig. 8 is an enlarged sectional view of the driving mechanism of. my amusement device.

Fig. 9 is a side .view ofa tie rod support. Fig. 10 is a vertical sectional .view of a part of the stationary platform on line 10.-10 Fig,

drive, but it :'is' understoodthat I.;-do not limit 90 .myselfto this particular .mannerrof operating 1, showing a modification of its top-surface."

Throughout'the views the samefreference nu-, merals apply to corresponding parts.

Referring to the drawings, is a circular stationary platform, preferably made of wooden F10 boards or beams 16 of wedge shaped contour, mounted on respective inner and outer circular, laminated sills 1'7; 18, by means of bolts or, other suitable appliances. 5 ,Sills 17, 18 form a sub-unit with-platform '15 parts being secured by means of bolts and brackets 21 or other suitable means, so as. to prevent the same from shifting. p

Posts 19'w i h'm e he -bema of onc et steel,1or wood, are anchored inithe earth or ground The top surface of platform 15 i's'partl-y covered with an annular sheet metal plate 22, which ca be-pbuilt in sections if so desired.

, 55 ,To the inner circular edge 23 of; platiorm'lfi are and said sub-unit rests on posts or pillars 19, the

secured a suitable numberof "roller-carrying brackets 24 which carry rollers 25. These rollers ZS-engage the rim 29 and thereby center the turn-- table 35.' The number .of 'rollers 25 :to be used may vary. It is merely essential that the turnfill: table be maintained in proper, position at all times by'said rollers. I v

A rail support 28. is connected to posts 26 by means of'ibrackets 27. This track support is pref-- erably made of Wooden boards or beams, and it Q 5 7 has on its top surface two

circular'metal rails

30, 31 which are held totrack support-28 ,by

'spikes32. 1 I

A suitable number of rollers33, held inbrackets '34 which are connected to the j lower surface of 7 0.

an annular .turn table 35, permit the latter to freely rotateon said metal rails.

:An angle iron :29 vis connected to the outer cylindricalsuriaoe ofisaid turntable and one leg of said angle iron is below and abuts the 715 it 40 meshes with a gear 61, mounted on shaft .62. 89

The shaft is lIlClll'ltediIl 'tW0 bearings 63;, 64 which are connected to the bottom surface of oneor more beams. Y Shaft 62- is driven by a motor 65 of any suitable type. This motor,'which;here is shown lo.- dated at the outer circumference: of the amusement device', mayvof "course be located underneath the platform if so'des'ired. 1 I have here shown a circular rack and gear the turn table and thatI may also employ a chain, belt, cable;"worm or. any other, kind of driving mechanism to suit-the conditions and require: ments'which may arise. l

Spaced from the common centre of the turn table and stationary platform,-yis 'a base shaft or pivot member '36, held vertically in a pillar- 37 which located ingroundzo. Rotatably held to said pivot .rnember'36'is, a-pivotbearing- 38yl00 composed of two circular: discs 1.40, ikepti separatedby circularly disposed posts39 and trunnions il secured .-;to saidplates. A sleeve or in sliing .42 riveted-orweldedto one or both of 'sai dplatesin ingsmay also be-substituted.therefondf :;so. do:- llll 7 sired. It isto be observed that the base shaftv 36 is foreshortened at its upper end as shown in Fig. 3, and therefore may be extendedupwardly to form a supporting means for a canopy or other cover (not shown) This shaft, 36 has a straight uninterrupted vertical axis and as such is well ing. To the outer ends of said rods are secured amusement carriages 46 of a type commonly used in connection with amusement devices of the character here described.

Each carriage is provided with a safety strap 4'7. Each carriage is further provided with a projection 48, which is connected with the rod 45 by means of a pivot member 49.

are provided swivel bearings 50. These locate and support carriage rods 45. Each bearing consists of a base plate 51, bolted to the turn table and 'a'circular swivel plate 52;-held freely turn-V able on said base plate by meansof a rod 53 which is secured to the base plate; Two uprights 54, preferably made of channel iron, are'welded on or may be riveted or bolted to swivel plate 52 and have on their upper flanges a top plate 55 with-a stud-or pin;66 in its centre.

A roller 67 held between uprights 54 and rotatable on a rod or bolt 68, supports carriage rod and provides an anti-friction bearing. Near the outer edge of the turn table and betwe'en swivelbearings 5O aresecured tie rod supports 70, which support tie rods 71, which-are connected to'supports 70=by members 72 and to pins-66on swivel bearings This arrangement provides a strong and rigid reinforcement of the swivel bearings. 1 r V The top surface of stationary platform 15 with sheet metal platel22 is shown to be planar in Fig. 1. Itis however possible to providethis top surface with curvatures, of, wave like nature, as

shown in Fig. 10, in which-a sheet metal plate. 74 is'shown securedto a curved top surface of 46 are mounted on rollers, as shown in Fig; 3, so 4 that they move in unison with rods 45. .The change of leverage during motion and 'the oscillating movement of-the carriages, as well as a slight radial displacement of the rods will cause the carriages to move in .a circle at the ends of said rods, thus causing a varietyof motions for the amusement of the occupants of the carriages. I

'If so desired the topsurface of the platform'wave-like as shown in Fig. 10. Rods 45 will thus be subjected simultaneously tofan up and down motion in bearing 50. 7 To provide for this, it isnecessary to increase the spacebetween roller 67 and top plate 55.

an additional up. and down motion of the carriages may be provided, by making r state vention is capable of various modifications with- ,out departing from the spirit of the: invention.

The appended claims are therefore intended to include such modifications of the invention as would occur to one skilled in the art to which the invention relates. 7 v g {I claim: I v t I 1.
