PROVISIONAL SPECIFICATION.
A Pleasure Riding Machine or Roundabout for Outdoor Amusement
Purposes.
1, JOHN GEORGE INSHAW, Laburnum House, Sutton Street, Aston, near.
Birmingham, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
I construct a circular tram or railway, on or near to the surface of the ground,
and in the centre of the said circular tram or railway 1 crect an upright shaft,
which may either be made to revolve or not according to the various circumstances
hereafter described. Near to the bottom of the said upright shaft and at angles
fix two or more branch shafts or axles which I incline upwards and outwards at
an angle of about 20 degrees. The said branch shafts or axles may either be
permanently fixed to the said upright shaft or may be arranged to revolve. The
said branch shafts I-use for the purpose of supporting two or more large platform
wheels furnished with flanges to run and take their bearing upon the said circular
tram or railway before described. And in order to take the undue strain that
would necessarily be brought to bear on the said branch shafts or axles, on account
of the oblique position in which they are fixed to the said centre shaft I place upon
the upper portion of the said upright shaft another platform wheel upon which the
other two or more platform wheels when placed upon the said branch shafts or
axles take their bearing at the top.
Upon the said platform wheels I fix a number of seats of any form, such as
horses chariots or ordinary garden seats, for the use of passengers.
Under the said two or more platform wheels when placed upon the said branch
shafts or axles, and upon the said upright shaft 1 fix the driving gear for driving
the said two or more platform wheels round upon the said circular tram or railway
by means of a steam engine or other motive power.
The said platform wheels may be made of any size in order to hold any number
of people who when riding make a revolution round the said branch shafts or axles,
and at the same time revolve round the said centre shaft before described.

page_text: which may either be made to revolve or not according to the various circumstances
hereafter described.
Near to the bottom of the said upright shaft and at angles I fix two or more
branch shafts or axles C on suitable arms or bearings D which may be fixed on the
upright shaft B when the said shaft revolves, or made to work loosely round the
said upright shaft B when it is stationary.
The said branch shafts or axles Cuse for the purpose of supporting two or
more large platform wheels E furnished with flanges F to run and take their
bearing upon the said circular tram or railway A before described.
In order to take the undue strain which would necessarily be brought to bear on
the said branch shafts or axles C on account of the oblique position in which they
are fixed.
I place upon the upper portion of the said upright shaft 13 another platform
wheel G upon which the other two or more platform wheels when fixed upon the
said branch shafts or axles C take their bearing at the top.
Upon the said platform wheels I fix a number of seats of any form such as horses
chariots or ordinary garden seats for the use of passengers.
I fix the driving gear for driving the two or more platform wheels beneath the
said two or more platform wheels.
The power may consist of a steam engine or other motive power.
The tram rails and flanges of the platform wheels may be provided with teeth or
cogs to prevent them from slipping, also the top wheel.
For the purpose of allowing the platforms to take their bearings against the tram
rail, the central pin which supports them is made sliding so that it shall
automatically adjust itself to any little inequalities as shewn on Fig. 4.
For this purpose it is fixed upon a plate H the said plate being provided with
two or more pins the said two or more pins working in slotted holes J in the
arms or supports of the platform.
As regards the central shaft it may be fixed in various ways and may be a fixed
solid shaft having the gearing and platforms revolving round it, or it may be made
so that part of it will turn round with the gearing or platforms as found
desirable.
It may also serve as a chimney for the steam engine or other motor.
The inclined shafts or axles may also be fixed in various ways and may be
fixed tightly on the arms or on the platforms in the latter case they would be placed
downwards for working in a hole or socket in the bearing arms D.
The space between the platform wheels is intended to be made up with
metal or other suitable protecting covering preferably ornamented to a suitable
design.
The platform wheels will be supported at the sides with suitable antifrictional
wheels K to act as a support and to enable them to run properly when unequally
loaded.
Thus it will be perceived that the power is applied to the bevelled wheel on
the central shaft to which is attached the branch armis D, the said branch arms
carrying the inclined shafts C.
The said branch arms D revolving round with the bevelled wheel and carrying
the platforms with them, the said platforms being supported at the bottom on
the circular tram or railway A & at top on the revolving wheel or platform G
& at the sides on antifrictional wheels K. Thus the platform besides revolving
round the central shaft B also revolves round the inclined shafts C.
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. A pleasure riding machine or roundabout having a platform wheel or wheels,
working at an angle round a central shaft B and having direct bearing on

page_text: a circular tram or railway which causes them to revolve round the said centre
shaft.
2. A pleasure riding machine or roundabout having a platform wheel or wheels
working at an angle round a central shaft. B and taking the bearing at the top on
the top platform wheel.
3. A pleasure riding machine or roundabout having a platform wheel or wheels
working at an angle round a central shaft B-and-having a direct bearing on a
circular tram or railway at the bottom which causes them to revolve and also having
a bearing at the top on the top platform wheel.
4. A pleasure riding machine or roundabout consisting of the parts arranged
and combined as substantially set forth in this Specification and illustrated by the
accompanying drawings..
