PROVISIONAL SPECIFICATION.
Improvements in Merry-go-rounds.
I, NESTOR ROLLand, of 117 Rue Verte, Brussels, Belgium, Civil Engineer, do
hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in merry-go-rounds, by means of which
the horses, care, or the like on or in which the passengers are seated, are not only
moved in a circle on a horizontal plane, but also round a centre in a vertical plane,
the said centre travelling round the said circle.
In my invention the central shaft or mast round which the parts revolve projects
vertically from a base on which is the motor. Surrounding this base is a circular
moving platform running on wheels travelling on a circular rail or rails and driven
by the motor. At intervals around this platform frames project upwards, the said
frames being in pairs parallel to one another and to a tangent to the circular
platform. Between the two frames constituting each pair a rotating shaft extends,
with a driving pulley at its inner end. Upon this shaft is mounted a circular frame
or wheel having cars or the like hung thereon, the whole resembling roughly the
paddle wheel of a steam boat. This wheel is driven by a belt or rope or the like
passing over the before mentioned pulley and over a driving pulley connected with
a wheel running on the circular rail, so as to take power from the said wheel when
the circular platform is rotated. A clutch serves to engage the driving pulley
directly or indirectly with the said wheel, or to free it therefrom when desired.
Dated this 4th day of March 1893.

Improvements in Merry-go-rounds.
I, NESTOR ROLLAND, of 117 Rue Verte, Brussels, in the Kingdom of Belgium,
Civil Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
My invention relates to improvements in merry-go-rounds, by means of which
the horses, cars, or the like on or in which the passengers are seated, are not only
moved in a circle on a horizontal plane but also round a centre in a vertical plane
the said centre travelling round the said circle.
In the following description reference is made to the accompanying drawing.
The central shaft or mast A round which the parts revolve projects vertically
from a base on which may be the motor. Surrounding this base is a circular
moving platform V running on wheels 00 travelling on a circular rail or
rails R R and driven by a motor. The said shaft or mast serves to support the
covering or canopy T. At intervals around this platform frames C project
upwards, the said frames being in pairs parallel to one another and to a tangent to
the circular platform. Between the two frames constituting each pair a rotating
circular frame or wheel
shaft M extends. Upon this shaft is mounted a
consisting of two parallel circles or rims F¹ F¹ connected by radial spokes F with
the said shaft M. The said wheel is further braced by means of the ties J J.

page_text: Mounted on the said wheel and on shafts extending between the two circles F¹ F¹
are cars or the like N in or upon which the passengers are seated the said cars
being loosely mounted upon their shafts so that they will always hang in a vertical
direction. At the inner end of the shaft M a pulley P is shown over which passes
the driving rope or belt B. The said driving rope B also passes over a pulley p
mounted upon a radial prolongation of the shaft a of the wheels 0 0.
The
movement of the wheels O upon the circular rail causes the shaft a and the pulley p
to rotate and so drive the pulley P and thereby cause the revolution of the wheels
upon which the passenger cars are mounted. The rate of revolution of the passenger
cars around the axle M depends as will be observed upon the relative sizes of the
pulleys P and p. X, V', S and Q are parts of a clutch or break serving to tighten
or slacken the driving rope B upon its pulleys and by means of which the vertical
wheels upon which the passenger cars are mounted may be stopped for the purpose
of enabling the passengers to enter or leave the cars (as for example by sufficiently
slackening the driving rope through the elevation of the handle V!).
The motor which drives the platform V may be of any convenient kind as for
example a man or a steam engine and this motor may drive the platform by
causing rotation of the wheels r and the toothed wheel R as shown in the figure.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The new or improved merry-go-round substantially as set forth.
2. The arrangement and combination of parts substantially as set forth.
