I WILLIAM PARKER of 24 King Street Bury Lancashire Cart and Waggon
Sheet Manufacturer do hereby declare the nature of my invention to be as
follows:-
My invention relates to apparatus for purposes of amusement at summer resorts
and the like, and commonly called roundabouts.
In roundabouts for imitating the motion of ships or boats at sea the oscillating
motion, when worked by manual labour, has hitherto been obtained by means of
ropes & meu standing underneath the platform & pulling down as the platform
revolved. I have now designed this invention with the object of producing the same
motion from the deck or platform, so that the men thus employed may assist in the
general management of the machine and the working of same, also by means of the
ship's wheels facilitating the loading & unloading of the platform or deck.
The nature and principle feature of my invention will be more fully understood
from the following description reference being had to the accompanying sheets of
drawings.
Similar letters refer to similar parts in each view.
Fig. 1 is a general view of the roundabout showing the method of applying my
invention.
Fig. 2 is an enlarged view of the mechanism I employ to obtain the oscillation,
& rigidity when loading & unloading.
In Fig. 1a is the vertical pillar upon the top end of which the circular platform
or deck b is suspended by means of the stays c which may be any number as
required. Supporting the vertical pillar are the struts & which are attached to the
bed or base d'. The stays c are hung from the disc e which revolves round on ball
bearings, and is turned by the wheelf by means of the pinion g which receives its
motion through the shaft h, from the engine below, thus giving the circular or
revolving motion.
Secured to the disc e, are the stays j in the form of a cross, upon the end of the
stays are fixed the chain pulleys k over which runs the chain one end of which
is secured to the top of the stands m which carries the ships wheels n the chain
then passes over the pulley k then down through a hole o, in the platform b then up
again through another hole p also in the platform b, then over the chain wheel q on
the axle of the ships wheel n, and is then secured to a staple r in the stand m.
The oscillating motion may be thus obtained by pulling down the chain / by
reason of its passing over the pulley k on the end of the stays j, or it may be
obtained by turning the ships wheel n & increasing the diameter of the chain
wheel g.
When the platform or deck b is loading or unloading, it is necessary to make it
rigid so that it may not sink down when the people crowd to one side, in order to
accomplish this, the chain is run over the chain wheel g by turning the ships
wheel n, this takes the chain up in the direction of the arrow s, and is wound
tightly on the chain wheel g, the ships wheel n is then made secure by passing a
looped rope over one of the spokes, the platform bis thus made perfectly rigid by
reason of the chain passing through the two holes o and p in the platform or deck b
as shown, the stand m with the ships wheel n, chain wheel 7 and chain / also chain
pulleys & may be two, three, four or more in number. By this arrangement the

chains are all pulling downwards from the pulleys k, on the end of the stays j
which are again secured by the rods t to the upper portion u, which revolves round
the chimney w.
The drawings herewith represents the application of the oscillating motion to my
Patent No. 20267, 1891 and is capable of application to all machines worked on a
similar basis.

Improvements in. Roundabouts..
I WILLIAM PARKER of 24 King Street Bury, Lancashire,. Cart and Waggon
Sheet Manufacturer, 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 :-
My invention relates to apparatus for purposes ofi amusement.at summer. resorts
and the like and commonly called. roundabouts..
In roundabouts for imitating the motion of ships or boats at sea, the oscillating
motion when worked by manual labour has hitherto been obtained by means of
ropes & men standing underneath the platform & pulling down. as the platform.
revolved.
I have now designed this invention with the object of producing the same-motion
from the deck or platform, so that the men thus employed may assist in the
general management of the machine & the working of same, also by means of
the ship's wheels facilitating the loading & unloading of the platform or deck.
The nature & principle features of my invention will be more fully, understood
from the following desoription, reference being had to the. drawings left with the
Provisional Specification:
Similar letters refer to similar parts in each view..
Fig. 1 is a general view of the roundabout showing the method of applying. my
invention.
Fig. 2 is an enlarged view of the mechanism I employ to obtain the oscillation &
rigidity when loading & unloading.
In Fig. 1a is the vertical pillar upon the top end of which. the circular. platform
or deck B is suspended by means of the stays C" which may be any number as
required." Supporting the vertical pillar a are the struts d which are: attached. to
the bed or base D'..
The stays C are hung from the diso E which revolves round on ball bearings &
is turned by the wheel F by means of the pinion. G. which. receives its motion
through the shaft H from the engine below thus giving. the circular or revolving
motion:
Secured to the disc E are the stays J in the form of a oross upon the end of the
stays are fixed chain pulleys K over which runs the chain L one end of which is
secured to the top of the stands M which carries the. ship's wheels N, the chain
then passes over the pulley K, then down through the hole O in the platform B
then up again through another hole P also in the platform. B; then over the chain
wheel on the axle of the ship's wheel N. &. is then. secured to a staple R in
the stand M.
The oscillating motion may be thus obtained by pulling down the chain L by
reason of its passing over the pulley K on the end of the stays J, or it may be
obtained by turning the ship wheel N & increasing the diameter of the chain
wheel Q.

page_text: When the platform or deck B is loading & unloading it is necessary to make it
rigid so that it may not sink down when the people crowd to one side in order to
accomplish this the chain L is run over the chain wheel Q by turning the ships
wheel N this takes the chain up in the direction of the arrow S & is wound tightly
on the chain wheel Q, the ships wheel N is then made secure by passing a looped
rope over one of the spokes, the platform B is then made perfectly rigid by reason
of the chain passing through the two holes O & P in the platform or deck B as
shown, the stands M with the ships wheel N chain wheel Q & chains L also
chain pulleys K may be two, three, four or more in number. By this arrangement
the platform or deck is screwed to the central structure in a firm rigid manner,
the chains L are all pulling downwards from the pulleys K on the ends of the
stays J which are again secured by the tie rods T to the upper portion U.
The drawings left with the Provisional Specification represent the application of
the oscillating motion to my Patent No. 20267 1891 and is capable of application
to all machines worked on a similar basis.
It will be clear to those familiar with the apparatus to which this invention
appertains that modifications may be made in the details thereof without departing
from the spirit of the invention & hence I do not limit myself to the exact con-
struction nor to the precise arrangement of the aforesaid parts.
Having now particularly described & ascertained the nature of my said invention
& in what manner the same is to be performed, I declare that what I claim is :—
1. Arranging the mechanism so that the rigidity or oscillating motion can be
actuated or worked from the deck or platform B whilst it is revolving substantially
as & for the purpose herein described & as shown.
2. The stage J with the chain pulleys K also the chain L or their equivalents
substantially as & for the purpose herein described & as shown.
3. The ship's wheels N with the chain wheel Qor their equivalents substantially
as & for the purpose herein described & as shown.
4. The combined arrangements of parts embodying my improvements for the
rigidity & oscillating motion of roundabouts substantially as & for the purpose
herein described & as shown.
Dated this 14th day of September 1895.
