It will be noted that the angularly turned ends 1 1 forma bed for the bracket, thus assuring a smooth running of the, device when 7 the crank shaft 26 is rotated and the seat caused to travel on its support around the central post or standard 12. I 7

It is believed obvious that the device is simple in its structure, while at the same time,it is durable and one which may be easily and quickly moved from place to place.

a pair of spaced bolsters mounted on each of said supports; hearings on said bolsters; a crank shaft rotatably mounted in said bearings; and a wheel on said crank shaft engaging said track.

2. A Whirligig of the class described, com prising: a hub; a supporting standard secured to and projecting upwardly from said hub; a plurality of legs secured to and projecting downwardly and outwardly from bolsters mounted on each of said supports; bearings on said bolsters; a crankshaft rotatably mounted in said bearings; a wheel on said crank shaft engaging said track; a seat on said seat supporting member; and pedals on said crank-shaft accessible to a person occupying-said seat for rotating said crank shaft. A w I 3. A Whirligig of the class described, comprising a hub; a standard projecting upwardly from said hub; supporting legs for said hub, the ends ofs'aid supporting legs being angularly turned to lie in a plane perpendicular to the axis .of said standard; a track'engaging said angularly turned ends of said legs; a plate rotatably mounted on said standard; a plurality of outwardly projecting portions on said plate; a seat supporting member secured toand projecting outwardly from each of said outwardly proecting portions; a pair of. spaced bolsters depending from said seat supporting memher; a brace connecting the innermost of said bolsters to said seat supportmg member, ad acent said outwardly'projecting portion to which attached; a shaft rotatably mounted and extending between said bolsters; and a wheel on said shaft and engaging said track.
