TRUVIDIONAL SPECIFICATION.
A Centrifugal Pleasure Machine or Roundabout for Out Door
Amusement Purposes.
I, JOHN INSHAW, Aston Manor Engineering Works Cheston Road Nechells
Birmingham Mechanical Engineer do hereby declare the nature of this invention. to
be as follows:-
I construct a platform of timber or other material, on the ground; and on this
platform I erect four or more columns of about thirty feet in height the base of
which I fix on the said plåtform at a distance of about four yards apart, and these
columns I bring together at the top and join them to a circular iron plate which
is provided with wrought Iron straps or hinges for that purpose, and in the centre
of the said circular plate I boro a hole three or more inches in diameter for the
purpose of steadying the top portion of an upright shaft of three or more inches
in diameter which extends from the said platform "on which it takes its bearing,"
to an height of about two feet after passing through the said hole in the circular plate
fixed as described on the top of the said columns. The top portion of the said
upright shaft is screwed and provided with binding nuts, for the purpose of making
fast another iron plate about five feet in diameter which has a hole in its centre
to receive the said shaft and when fixed as described this plate overhangs the
plate which is fixed on the said columns. This top plate is provided with six or
more, wrought iron hinges which are fixed at equal distance round its periphery,
for the purpose of carrying as many arms or links, which after being hinged to.
the said top plate as described continue downwards for a distance of about twenty
five feet and are thus at liberty to viberate to and from the centre shaft.
On the bottom of the said hinged arms or links I fix the carriages "at a distance of
about one foot above the said platforms" and these carriages may be made in any design,
and to accommodate any number of people as may be considered best, so that when the
said upright shaft is driven round the said arms or links with the said carriages
thus fixed, commence to fly out centrifugally to an height which is determined by
the speed in which the said shaft is driven. For driving this shaft I use a bevil geared
wheel which I fix about a foot from the bottom of the said upright shaft, and
into this wheel I run a pinion, which I fix on a horizontal shaft which I run across
the said platform to a suitable distance for gearing same to steam or other motive
power for which purpose a belt or other means may be applied.

I JOHN INSHAW Aston Manor Engineering Works, Cheston Road Nechells
Birmingham Mechanical Engineer, doth 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 :-
I construct a platform A of timber or other material on the ground and on this
platform I erect four or more columns B about 30 feet in height, the bases of
which I fix on the said platform at a distance of about 4 yards apart, and these
columns I bring closer together at the top and join them to a circular iron plate C,
which is provided with wrought iron straps or hinges for that purpose and in the
centre of the said circular plate I bore a hole of three or more inches in diameter
מ

page_text: for the purpose of steadying the top portion of an upright shaft DD which extends
from the platform; the said platform being provided with a suitable step or bearing
to receive the said shaft; the said shaft extends to a height of about two feet
after passing through the said hole in the circular plate fixed as described at the
top of the said column the top portion of the said upright shaft is screwed and
provided with nuts and washers for the purpose of making fast another iron plate E
about five feet in diameter, which also has a hole in the centre to receive the said
shaft and when fixed it overhangs the said plate C, which is fixed on the said
oolumns and this top plate is provided with six or more wrought iron hinges which
are fixed at equal distances round the said top plate for the purpose of carrying
six or more wrought iron arms hangers or chains F which after being hinged or
jointed to the said top plate continue downwards for about twenty five feet and are
thus at liberty to swing to and from the centre shaft.
On the bottom of the said hinged arms hangers or chains are fixed the carriages G
at a distance of about one foot above the platform, these carriages may be mado in any
design and to accommodate any number of people that may be considered safo.
When the said shaft is turned round the said arms with the said carriages fixed as
described commence to fly out centrifugally (as indicated by dotted lines Fig. 1) to a
height which is determined by the speed at which the said shaft is driven, and upon
the withdrawal of the power lower themselves gradually until they rest against the
rings H. The said rings being connected with the top plate and revolving with it.
For driving the said shaft I use bevel wheels which may be fixed on any portion of
the said shaft which I drive either by a small steam, gas, or any other kind of engine
or mechanical power, for which power either a belt or other means may be employed.
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 1
claim is
1. A roundabout having the carriages &c. suspended by arms or hangers, the said
arms or hangers being hinged at the summit to a plate which when revolved causes
the carriages to rise by centrifugal force as substantially set forth and illustrated by
the accompanying drawings.
0
2. A roundabout having the carriages &c. suspended by arms or hangers the said
arms or hangers being hinged to and radiating from a central top plate, the said plate
being supported by and revolving on an upright revolving shaft as substantially, set
forth and illustrated by the accompanying drawings.
3. A centrifugal roundabout consisting of the parts arranged and combined as
hereinbefore set forth and illustrated by the accompanying drawings.
