PROVISIONAL SPECIFICATION.
Improvements in the Construction of Roundabouts.
I, GEORGE SPENCER, 87 Market Street, Hyde, Cheshire, Watchmaker, do
hereby declare the nature of this invention to be as follows:-
On a strong bed about 8 feet from the ground is fixed a wheel A which has an
hole in centre for a strong cylindrical chimney B to work through. Attached to
this chimney is a boss to hold arm C and which will be supported at the other end
by iron rods from top of chimney. Every two of these arms will be connected by
hangers D, these hangers will bear a strong iron platform E. On the platform
and immediately under the arms C will be fixed a wheel F to work with stationary
wheel A, this wheel F will revolve round a strong iron pin G. On this wheel F is
an upright arm H. At a proper distance from wheel is fitted to work a lever I.
At the end nearest to the wheel it has a broad end with a slot in centre for upright
arm H to work in, the other end has to reach nearly to end of arm C. At the end
of arm C is suspended by iron rods J a boat K, the rod nearest the centre is
arranged to have a slot L down centre for lever I to work in. So, when the
wheels F revolve round the stationary wheel A the upright arm H working in slot
of lever I will move lever at the outer end working in slot L of rod J the boat K
will therefore be pushed backwards and forwards while making the circle. In
place of the boats, horses could be used to swing in the same manner.
In the drawings accompanying this application, Fig. 1 shows plan. Fig. 2 end
view. Fig. 3 the lever. Fig. 4 the boat and iron rod with slot down centre.
Fig. 5 shows wheel F and an arrangement to increase the swing of the boat at the
commencement of their working, by pushing upright arm H along a slot from near
centre to near outside edge of wheel, whereby the swing of the boat would get
greater as the arm was pushed out. The whole would be worked in the ordinary
manner of steam horses etc.

COMPLETE SPECIFICATION.
Improvements in the Construction of Roundabouts.
I, GEORGE SPENCER 87 Market Street, Hyde, Cheshire, 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 :—
On a strong bed about eight feet from the ground is fixed a wheel A which has
an hole in the centre for a strong cylindrical chimney B to work through.
Attached to this chimney is a boss to hold arm C and which will be supported
at the other end by iron rods from top of chimney. Every two of these arms will
be connected by hangers D, these hangers will bear a strong iron platform E. On
the platform and immediately under the arms C will be fixed a wheel F to work
with stationary wheel A, this wheel F will revolve round a strong iron pin G. On
this wheel F is firmly secured an upright arm H near to edge of wheel. At a
At the end nearest the
proper distance from wheel is fitted to work a lever I.
wheel it has a broad end with a slot in the centre for upright arm H to work in,
the other end has to reach nearly to the end of arm C.
At the end of arm C is
suspended by iron rods J a boat K. The rod nearest the centre is arranged to
have a slot L down the centre for lever I to work in. So, when the wheels F

page_text: revolve round the stationary wheel A and the upright arm H working in slot of
lever I it will move lever at outer end working in slot L of rod J, the boat K will
therefore be pushed backwards and forwards while making the circle. In place of
the boats horses could be used to swing in the same manner. The whole would be
worked in the ordinary manner of steam horses etc.
In the drawings which I left with the Provisional Specification and which I wish
to adopt for this Complete Specification, Fig. 1 shows plan. Fig. 2 end view.
Fig. 3 the lever. Fig. 4 the boat and iron rod with slot down centre. Fig. 5
shows wheel F and an arrangement to increase the swing of the boat at the com-
mencement of their working, by pushing upright arm H along a slot from near
centre to near outside edge of wheel, whereby the swing of the boat would get
greater as the arm was pushed out. It is optional whether this arrangement is
used or not.
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,
First. The wheel F with the upright arm H.
