PROVISIONAL SPECIFICATION.
Improvements in Roundabouts.
I, JOHN EDWARD COOPER of Chapel Street, Drypool Hull in the County of
Yorkshire Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to roundabouts in which vehicles representing boats or
other forms of car are propelled on a circular track by means of radial arms
extending from the centre, and actuated by steam or other motive power. The
object of this invention is to impart to said boats or other form of carriage, for the
purpose of amusement, a combined pitching and rolling motion. In this invention
place a central pivot with rods or arms extending therefrom, the outer end of
each of said rods or arms being connected to each other at any preferred distance
from the centre by means of ties or stay rods. place a pair of wheels mounted
on an axle opposite the end of each of said rods or arms and connect the inner end
of the axle of said wheels to the end of the projecting rod or arm; I place a pair
of wheels mounted on an axle on each side of aforesaid pair of wheels and at a
suitable distance therefrom; I mount a car in the form of a boat or other repre-
sentation on each set of three pairs of wheels by means of a pedestal affixed to
the axle of the centre pair of wheels in each set, said pedestal being formed at its
upper end with a cup and ball joint which is also affixed to the underside of boat
or car. In order to obtain a pitching motion as the boat or car is propelled round
the track I place an eccentric in reverse positions on the axle of both the leading
and trailing wheels, and for the purpose of obtaining a rolling motion I place two
eccentrics on the axle of the central pair of wheels each of said eccentrics being
placed at a suitable distance apart and in reverse positions. By these means a
combined pitching and rolling motion is imparted to the boat or car during progress
around the track. The track may be of the usual construction of a circular
railway, and the cars or boats may be propelled by means of hand, steam or other
motive power, and the ordinary form of mechanism.

Improvements in Roundabouts.
I, JOHN EDWARD COOPER of 70 Church Street, Drypool, Hull, in the County
of Yorkshire, 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 :-
This invention relates to roundabouts in which vehicles representing boats or
other forms of car are propelled on a circular track by means of radial arms
extending from the centre and actuated by steam or other motive power. The
object of this invention is to impart to said boats or other form of carriage for the
I attain this
purpose of amusement, a combined pitching and rolling motion.
object by the means hereinafter described and as illustrated in the accompanying
sheet of drawings. In the several views therein shown similar letters refer to
similar parts.
Fig. 1. is part plan of a circular track with carriages in the form of boats
aled the non

represent some of the positions that said boat or carriage would occupy at different
periods during the journey round the track.

In this invention I place a central pivot such as a with rods or arms 6 extending
therefrom, the outer end of each of said rods or arms being connected to each
other at any preferred'distance from the centre by means of ties or stay rods c. I
place a pair of wheels mounted on an axle & opposite the end of each of said rods
or arms, and connect the inner end of the axle of said wheels to the end of the
projecting rod or arm b. I place a pair of wheels fand k mounted on an axle
and on each side of aforesaid pair of wheels d and at a suitable distance there-
from; I mount a car h in the form of a boat or other representation on each set of
the three pairs of wheels d, f, and k, by means of a pedestal l affixed to the axle e
of the centre pair of wheels d in each set, said pedestal, which may slide on 'the
axle, being formed at its upper end with a cup and ball joint which is also affixed
to the underside of boat or car h. In order to obtain a pitching motion as the boat
or car is propelled round the track, I place an eccentric m in reverse positions on
the axles and j
of both the leading and trailing wheels f and k and for the
purpose of obtaining a rolling motion, I place two eccentrics o and p on the axle e
of the central pair of wheels d, each of said eccentrics being placed at a suitable
distance apart and in reverse positions. By these means a combined pitching and
rolling motion is imparted to the boat or car during progress around the track.
The track may be of the usual construction of a circular railway, and the cars or
boats which may vary in number and relative positions, may be propelled by means
of hand, steam, or other motive power, and the ordinary forms of mechanism.
g
Having now particularly described and ascertained the nature of this my said
invention and in what. manner the same is to be performed, I declare that
what I claim is,
In roundabouts in which vehicles representing boats or other forms of carriage
are propelled on a track by means of steam or other motive power, the mechanism
for imparting to said boats or other forms of carriage, a combined pitching and
rolling motion, for the purpose and in the manner substantially as herein before
described.
