PROVISIONAL SPECIFICATION.
Improvements in Roundabouts.
I GEORGE GREEN Junior of 5 East Cliffe Road, Preston, Lancashire, Watchmaker
do hereby declare the nature of this Invention to be as follows:-
This Invention relates to that class of roundabouts wherein a series of platforms or
trucks carrying representations of animal figures, chairs, or other seats, are rotated
upon an undulating path or track and the present Invention has for its object
Improvements in the construction of the said track and in the manner and means for
carrying the platform or trucks thereon. Under the Invention the track consists of
two concentric circular paths the undulations of which practically correspond. At or
near the centre of its breadth each truck or platform has a carrying wheel or wheels
resting upon the inner path or track which is lower than the outer path or track and
at or near its outer side each platform has a wheel or wheels resting on the upper side
of the outer path or track and another wheel or wheels resting and rotating.against
the under side of the said path or track. The wheels in conjunction with the outer
path or track are or may be flanged. The trucks or platforms are connected together
at their ends and over the joint a bar or roller laid loosely. The bar or roller
extends throughout the breadth of the truck and over it a strap or band is placed the
ends of which are connected to a plate lying underneath the adjacent edges of the
trucks. The rollers or bars accomodate themselves to any difference in the planes of
the platforms or trucks and prevent any gap between them.

COMPLETE SPECIFICATION.
Improvements in Roundabouts.
I, GEORGE GREEN Junior of 5 East Cliffe Road, Preston, Lancashire, 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 that class of roundabouts wherein a series of platforms or
trucks carrying representations of animal figures, chairs or other seats, are rotated
upon an undulating path or track and the present Invention has for its object improve-
nients in the construction of the said track and in the manner and means for carrying
the platforms or trucks thereon.
Under the Invention which is illustrated by the several figures on the accompanying
drawings (figure 1 being a vertical section through the diameter of the circular track,
figure 2 a plan, figure 3 a cross section, drawn to a larger scale, of the track and one
truck and figure 4 a plan also to a larger scale of a truck frame) the track consists of
two concentric circular paths a b, the undulations of which practically correspond,
these paths being carried by the framing c, d the latter of which has a flooring e
affording a path around the apparatus. At or near the centre each truck or platform,
has a carrying wheelf, resting upon the inner path or track a which is lower than the
outer one band is grooved on the tread and at or near its outer side each platform has
a wheel or wheels g resting on the upper side of the outer path or track 6 and another
wheel or wheels rotating against the under side of the said path or track. The
wheels 9, h or the wheels g only are or may be flanged as shewn. The trucks or
platforms are connected together by V shaped swinging pieces k which are inserted

page_text: between their adjacent ends the said piece having at its narrower extremity a strap 1,
centred on a pin m, and jointed to the platform at each side by pins n. whilst at its
broader end the piece k, has straps o, bolted to it these being jointed by pins to the
ends of the trucks or platforms, or the trucks or platforms may be otherwise connected
together.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a roundabout a track consisting of two concentric rails or paths one being at
a lower level than the other and both having undulations which practically correspond
substantially as described with reference to the drawings annexed.
2. In a roundabout a platform or truck having a carrying wheel or wheels, at or
near its centre, rotating upon an inner path or rail and at or near its outer edge
wheels rotating upon a concentric path or rail the latter wheels being arranged in
pairs to bear upon both the upper and under side of the rail substantially as described
with reference to the accompanying drawings.
3. In a roundabout a platform or truck having a wheel or wheels running vertically
against the underside of a track substantially as described with reference to the
appended drawings.
Dated this Seventh day of January 1890.
