PROVISIONAL SPECIFICATION.
Improvements in Roundabouts.
I ALLEN RIDGE of Townley Iron Works, Bradford near Manchester in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to be
as follows:-
"
This invention consists principally in mounting the seats of "roundabouts" upon
planks pivoted at or about the centre and in imparting to the latter a (:
movement as the roundabout revolves.
see-saw
The platform or floor of the roundabout is provided at suitable intervals with
pillars or standards to which the planks are pivoted. The platform turns upon a
central pillar or shaft and is supported on wheels running upon a circular rail or
path fixed beneath the same, and each wheel is fixed upon a crank shaft provided
with two or more cranks set at varying angles to each other, each crank being
connected by a link to one of the pivoted planks or
* see-saws above the platform.
Or crank pins on the face of the wheels may be employed.
"
Each plank may have one scat at each end and one at the centre and it will
be evident that as the "roundabout" revolves the wheels running on the circular
rail or path will by means of the cranks or crank pins and connecting links give
at the same time a rocking or «
see-saw motion to the planks to which the seats are
attached.
I prefer to make the platform in sections with joints radiating towards the
centre so that upon removing the bolts and reversing each alternate section the
whole can be arranged in a straight line for convenience of travelling.

COMPLETE SPECIFICATION.
Improvements in Roundabouts.
I ALLEN RIDGE of Townley Iron Works Bradford near Manchester in the County
of Lancaster 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:-
upon
This invention consists principally in mounting the seats of "Roundabouts"
planks pivoted at or about the centre and imparting to the latter a sew-saw
movement as the "roundabout" revolves.
"
The manner in which my invention is to be performed or carried into practical
effect will be readily understood on reference to the sheet of drawings hereunto
annexed and the following explanation thereof.
"

Fig. 1. on the drawing is a vertical section and Fig. 2 a plan view of so much
of a roundabout as is necessary to illustrate the application of my invention thereto.
The revolving platform or floor a of the "roundabout" is provided at suitable
intervals with pillars or standards b to which the planks or see-saws c are pivoted.
The platform a turns upon a central pillar or shaft in the usual manner and is
supported on wheels d running upon a circular rail or path fixed beneath the same,
and each wheel d may be fixed direct upon a crank shaft, but I prefer to mount these
running wheels d upon a counter shaft e which by means of the spur gearing drives
the crank or excentric shaft g at a slower speed. The shaft g is provided with cranks
or with excentrics h which are set at varying angles to each other, each crank or
Pin21

above the platform a.
"Sew-saws 22 C
Each plank may have a seat, at each end, and another at or near the centre, the
end seats & being mounted on pivots so that they can be placed either across or side-
ways as may be preferred; and it will he evident that as the "roundabout" revolves
the wheels d running on the circular rail or path will by means of the spur gearing f
and cranks or excentrics and connecting links i, give at the same time a rocking
or "sew-saw" motion to the planks e to which the seats are attached.
I prefer to make the circular platform a in sections with joints radiating towards
the centre so that upon removing the bolts and reversing each alternate section
the whole can be arranged in a straight or wavy line for convenience of travelling.
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
The combination with the revolving platform of a roundabout, of a series of "see-
saws" caused to rock by cranks or excentrics, actuated by the revolution of the
wheels upon which the revolving platform runs, substantially as hereinbefore described
and illustrated by the drawings annexed.
