An Improved Apparatus for Public Recreation.
I, DAVID YOUNG, Patent Agent, of the Firm of D. Young & Co.,
11 & 12 Southampton Buildings, London, W.C. 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 an apparatus for public recreation, comprising a tower
or shaft-shaped building provided with a roof, inside which, on a ring-shaped
platform, is arranged a car provided with seats and receiving a simultaneous turning
and up-and-down movement.
In the accompanying drawing:-
Figure 1 is a longitudinal section, and
Figure 2 a plan, partly in horizontal section, showing the said apparatus.
A tower or shaft is formed of several vertical columns or pillars a, a, arranged
in the form of a cross at equal distances apart, in such a manner that a ring-
shaped platform b, which is arranged to slide between the pillars by means of
guide-forks or shoes, can be propelled up and down therein by means of a windlass
arrangement. On a circular rail or way c on this platform is rotatably mounted a
cylindrically formed car d provided with seats e, which car is supported by means
of a number of wheels or rollers o.
In the centre of the said shaft is erected a screw-threaded rod or pillar g, the
thread of which is of very rapid pitch; the said pillar is mounted on a
very rigid seating at its lower end and is provided with a nut rigidly secured
to the car d.
By means of the said windlass, the freely sliding but not rotatable platform b
is raised or lowered in its guides working on the outside of the shaft, the car d
freely resting on this platform, therefore, simultaneously receives this motion, and
also the rotary motion imparted to it by the screw-threaded pillar g through the
nut rigidly secured to the said car.
The upper part of the shaft is provided with a circular balcony k, which, on the
arrest or cessation of the simultaneous raising and rotary motion, serves as an
entrance to a return passage for the public at the top. Moreover, in a modified
form, the apparatus can be constructed with two towers or shafts near to one
another, in such a manner that the weight of the loaded descending platform is
employed in lifting the platform of the other shaft, which is connected
therewith by chains or ropes l. In this case the balconies of the two shafts
are connected by means of a passage m. Each platform is thus employed
for lowering in conjunction with the windlass of the opposite shaft; during the
stoppage of one shaft, the windlass comes into operation both during raising and
lowering.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is :-
The improved apparatus for public recreation, comprising a platform (b)
provided with a circular rail or way (c) and capable of being moved up and down
between pillars (a, a) by means of a windlass arrangement, and a cylindrical

page_text: car (d) provided with seats, which rests freely on the rail of the platform by
means of wheels or rollers (o) and simultaneously receives a rotary motion by reason
of the up-and-down movement of the platform and its rigid connection with a nut
which works on a screw-threaded rod in the centre of the pillars, substantially as
hereinbefore described.
Dated this 31st day of March 1894.
