SPECIFICATION forming part of Letters Patent No. 261,734, dated July 25, 1882.

Application filed April 17, 1882. (No model.)

chine, and Fig. 2 is a vertical crosssection of the same.

Similar letters of referenceindicate corresponding parts in both the figures.

My invention has relation to that class of devices for recreation and amusement which` are known as rotary swings,7 or by the more popular term of flying-horse machines 5 and it consists in the detailed construction and combination of parts of a machine of thatclass, as hereinaftermore fully described and claimed.

In the 'accompanying' drawings, A represents a frame of suitable size and construction, within which is inserted a vertical shaft, B.

C is a platform of circular shape, havinga raised circumferential edge or railing, c. This platform is mounted upon shaftB, which passes through its center, by arms D D, which are inserted through the shaft or post B at right angles to each other.

E E 'are .braces for bracing the outer ends of the supporting-arms D against the lower part of post B; and F is an arm or lever which projects at right angles from post B.

Platform G has an aperture, a, of such size that a person `may easily pass upor down through it, and a suitably-constructed ladder or stairway, G, leads from this opening down along post B, supported at 'its lower end upon one of the oblique braces E. This stairway extends to within ashort distance of the ground or iioor upon which the machine is mounted, so that persons may conveniently ascend or descend.

Seats H (which may represent horses, swans, sleighs, 8vo.) are placed upon platform C, near itsrailing c, for the occupancy of persons riding on the platform. When used in thel open air it is desirable to cover the entire machine with an awning of canvas or other suitable material, which may either rotate with the platform, or it may he fixed upon the framework within which this is mounted and rotates.

The rotary platform may be made of any del sired size to accommodate from fty to one yhundred persons or more; and the motive power which is applied tov the lever F may be horse-power or man-power, according to the size of the machine. By making lever F of suflicient length one man can easily work a machine seating fifty persons.

Having thus described my invention, I claim 'and desire to secure by Letters Patent of the United States- In a rotary swing or roundabout, the horizontal rotary platform G, having the manhole a, and provided with the stairway Gr, arranged under the man-hole and fixed upon and rotating with the platform, as shown and set forth..

A In testimony that I claim the foregoing as my own I have hereunto aiiixed my signature in presence of two .witnesses ERIOK LARSON.
