Improvements in Roundabouts.
I, GEORGE GREEN, junior, of 83 Back Lane, Preston, in the County of
Lancaster, Watchmaker, do hereby declare the nature of this invention to be as
follows:-
According to this invention my improved roundabout comprises a circular platform
or table which rotates upon and around a fixed central pillar or pivot. The pillar or
pivot stands obliquely to the horizontal or ground line causing the platform or table
to stand and to rotate in a plane at an angle (preferably of about 20 degrees) to the
horizontal. The upper extremity of the pillar or pivot projects somewhat above the
centre of the rotatory platform and being a fixture permits of the arrangement upon
and around its summit of a table or structure for the accommodation of musicians, an
organ, or other musical instrument. Upon the upper side of the rotatory platform
are placed the chairs, imitation animals, or other accessories for a like purpose
usually employed in connexion with such apparatus.
The central part or eye of the platform fits within the projecting double flange of a
metal boss or sleeve which revolves upon the central pillar or pivot, the bottom edge
of the boss or sleeve bearing upon a collar or flange upon the pillar. Near to the
bottom of the pillar a second double flanged boss or sleeve and collar are provided the
second or lower boss receiving the inner ends of radial arms whose other ends project
diagonally to the underside of the platform to which they are fastened and thus form
stays or struts to support the outer weight of the platform.
Friction-roller or any other convenient form of bearings may be employed in con-
junction with the revolving bosses or sleeves and the usual wheel gearing arrange-
ments and steam or other motive power may be employed for driving or rotating the
apparatus.

page_text: I, GEORGE GREEN Junior, of 83 Back Lane, Preston, in the County of Lancaster,
Watchmaker, 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:-
This Invention relates to improvements in roundabouts and as seen in vertical section
at figure 1 of the annexed drawings the improved apparatus comprises a circular
platform or table A which is supported and rotates upon or around a fixed central
pillar B, the latter being as seen more particularly in elevation at figure 2 and in
transverse section at figure 3 stepped into a sleeve or socket C, which rests upon and
is secured to cross beams D constituting the base or foundation of the roundabout by
means of angle iron or other brackets or stays E. The pillar B stands obliquely to
the horizontal or ground line causing the platform or table A to lie and rotate in a
plane at an angle (preferably of about 20 degrees) to the horizontal. The upper end of
the pillar B projects somewhat above the centre of the rotatory platform and being
stationary it permits of the arrangement upon its summit of a platform F for the
accomodation of musicians, an organ or other musical instrument or source of attrac-
tion. Upon the upper side of the rotatory platform are placed the seats G or imitation
animals or other accessories for the like purpose usually employed in connection with
such apparatus. Between the upper edge of the socket C and the underside of the
platform a sleeve H is placed over the fixed central pillar the said sleeve having at its
upper end a flange a to which a metal boss I constituting the centre or eye of the
rotatory platform is secured. The boss I may either be made as shewn that is to say
with a single flange or collar 6 supporting the table or platform A or it may have a
second flange or collar at its upper part the eye of the platform fitting within these
two flanges. Near to the socket C a second boss J constitutes part of or is secured to
the sleeve H the said boss having two projecting flanges or collars c the space within
which receives the lower ends of radial arms K whose upper ends project diagonally
to the underside of the platform A to which they are fastened thus forming stays or
struts to support the outer weight of the platform. To the underside of the boss J
there is secured another boss L carrying the usual gearing wheel M through which
the platform A is rotated from a steam engine or other motive power. To reduce or
lessen friction the bosses I and L are fitted with rollers & bearing on the pillar B and
the boss L, which constitutes the lower end of the sleeve H and may be made in one
piece with the boss J if desired rests on ball bearings e which rotate in a path made
in a plate resting on the top of the socket C.

page_text: 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 general combination of parts constituting the improved roundabout herein-
before described with reference to the appended drawings.
2. In a roundabout supporting the rotative table or platform substantially as herein-
before described.
3. In a roundabout a support for the rotative table or platform consisting of an
oblique fixed pillar a sleeve on said pillar extending below the platform and to which
the platform is connected struts extending from said sleeve to the platform and means
for rotating the said sleeve substantially as described with reference to the accom-
panying drawings.
4. In a roundabout the combination of an oblique fixed pillar and a horizontal
stationary platform substantially as and for the purpose set forth.
