I GEORGE FREDERICK LÜTTICKE, of No. 50, Cromwell Road, Hove, in the County
of Sussex, Merchant, do hereby declare the nature of this invention to be as
follows:
--
This invention relates to improvements in roundabouts whereby the person or
persons using the roundabout is enabled to communicate motion thereto in the manner
hereinafter more particularly described.
My improved roundabout is constructed of a vertical shaft fixed in a suitable
foundation or support and provided at its lower end with a toothed wheel which is
securely fixed thereto. Over the vertical shaft is placed a hollow shaft or sleeve
closed at its upper end the said closed end resting on the top of the vertical shaft on
which it revolves. At a short distance above the said wheel the sleeve or hollow shaft
is provided with a horizontal rod and firmly fixed by means of suitable stays. At
the outer end of the said rod is fixed a child's chair or other seat, or a horse, a boat,
or the like and such seat is provided with a toothed wheel gearing with the above
named fixed toothed wheel, the wheel on the seat being provided with a vertical
shaft working in a suitable bearing or bearings and adapted to be turned by
means of a handle which can be conveniently operated by the person sitting in the
chair. By this arrangement it will be obvious that if the person occupying the seat
turns the above named handle the seat and the person in it will be moved in a circle
around the fixed vertical shaft.
It will be obvious that the apparatus can have more than one seat and instead of
cog gearing, chain wheels and chains or equivalent gearing may be employed for
operating the roundabout.
It will also be obvious that any suitable motive power may be substituted for the
hand in setting and keeping the roundabout in motion.

page_text: I, GEORGE FREDERICK LÜTTICKE, of No. 50, Cromwell Road, Hove, in the County
of Sussex, Merchant, 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 improvements in roundabouts whereby the person or
persons using the roundabout is enabled to communicate motion thereto in the manner
hereinafter more particularly described.
My improved roundabout is constructed of a vertical shaft fixed in a suitable
foundation or support and provided at its lower end with a toothed wheel which is
securely fixed thereto. Over the vertical shaft is placed a hollow shaft or sleeve
closed at its upper end, the said closed end resting on the top of the vertical shaft on
which it revolves. At a short distance above the said wheel the sleeve or hollow shaft
is provided with a horizontal bar which is firmly fixed by means of suitable stays.
At the outer end of the said bar is fixed a child's chair or other seat, or a horse, a
boat or the like, and toothed wheels are provided on or near such seat operating a
toothed wheel gearing with the above named fixed toothed wheel. One of the wheels
on or near the seat is provided with a vertical shaft working in a suitable bearing or
bearings and adapted to be turned by means of a handle which can be conveniently
operated by the person sitting in the chair.
It will be obvious that the apparatus can have more than one seat and instead of
cog gearing, chain wheels and chains or equivalent gearing may be employed for
operating the roundabout.
It will also be obvious that any suitable motive power may be substituted for the
hand in setting and keeping the roundabout in motion.
In order to enable my invention to be fully understood I will describe how it can
be carried into practice by reference to the accompanying drawing in which
Figure 1 is a perspective view of a roundabout constructed according to my
invention and arranged to be operated by toothed gearing and a handle.
Figure 2 is a vertical section drawn to an enlarged scale of the top part of the
vertical shaft and sleeve or hollow shaft.
Figure 3 is an elevation illustrating how my roundabout can be operated by chain
gearing and treadles.
Similar letters in all the figures indicate similar parts.
a is the vertical shaft which is advantageously fixed to a support or base b by means
of stays c, c, c, c; d is the toothed wheel fixed to the shaft a.
e is the hollow shaft or sleeve closed at its upper end as clearly shewn in Figure 2
and placed over the vertical shaft a, the closed and resting on the top of the shaft a.
fis the horizontal bar fixed to the hollow shaft or sleeve e by means of stays 9, 9;
are the chairs or seats at each end of the bar f.
h,
i and are the toothed wheels arranged near the chair A. k is the toothed wheel

page_text: operated by the wheels i and through the shaft to which the wheels ; and k are
fixed. The wheel k gears with the fixed toothed wheel d as shown.
m is the vertical shaft with which the toothed wheel i is provided; n is the bearing
of the shaft m, and o is the handle for turning the said shaft, the handle being
conveniently placed so that it can be operated by the person seated in the chair h¹ as
shewn.
It will be readily understood without illustration that the roundabout could be
driven by a chain and chain wheels instead of toothed gearing, as herein before
described the chain wheels in that case being placed upon the fixed vertical shaft a
and handle shaft m respectively.
By this arrangement it will be obvious that if the person occupying the seat h¹
turns the handle o the seats and the persons in them will be moved in a circle around
the fixed vertical shaft a.
When employing the arrangement of operating mechanism illustrated by Figure 3
the construction of the roundabout is the same as that shewn in Figure 1, therefore
only sufficient of the apparatus is drawn to clearly illustrate the modification.
p is the chain passing round two chain wheels fixed respectively to the shaft and
treadle or crank shaft q having their bearings in the seat frame.
If the treadles q be worked by the person occupying the seat, motion will, through
the chain gearing, be communicated to the shaft and toothed wheel k and the
roundabout will be thereby operated.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what I
caim is:
1. A roundabout consisting essentially of a fixed vertical shaft having a toothed
wheel or its equivalent fixed thereto, a hollow shaft or sleeve placed over and adapted
to revolve around the said fixed shaft, and suitable gearing in connection with the
fixed wheel for communicating the required circular motion.
2. The improved roundabout hereinbefore described and illustrated in Figure 1 of
the accompaying drawing.
3. The modified arrangement of mechanism for driving a roundabout as herein-
before described with reference to Figure 3 of the accompanying drawing.
