COMPLETE SPECIFICATION.
Improvements in Swing Roundabouts.
A communication to me from abroad by FRIEDRICH NAUMANN, of Crethen, in the
Empire of Germany, Engineer.
I, EDMUND EDWARDS, of the firm of Edwards and Co., Patent Agents and
Engineers, of 35, Southampton Buildings, Chancery Lane, in the County of
Middlesex 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 and accompanying drawing (that is to say) :-
In the ordinary roundabouts used in fairs and other places of amusement, the plane
of revolution is either horizontal or vertical, and the present invention has for its
object a novel method of construction and arrangement of the parts by which a
movement both in a horizontal and vertical plane simultaneously is effected.
In the accompanying drawing, which is in illustration of the invention, figures 1
and 2 are front and side views respectively, and figure 3 is a front view of a
modified method of construction. The same letters of reference indicate the same
parts in the several figures.
The rotating swing is supported upon the upper end of a column or post A of
wood or metal firmly fixed upright upon a foundation or in the ground. The upper
end of this column is fitted with a metal cap B having a dished recess in which
revolves and oscillates a strong steel or other pin C which is fixed at the centre of
an anglebeam D of wood or metal of sufficient strength, the outer ends of the arms
of which are fitted with rings and double hooks or shackles to which are suspended
the double cars or carriages E, in which the riders sit.
These cars are provided with steps by which access to or from them is obtained,
and ropes are also provided by which the swing can be pulled round and made to
oscillate or the occupants can themselves produce the required movements.
In order to properly balance the weight of the persons sitting in the cars E, the
arms D are provided with vertical hars F connected to horizontal ones G upon which
are suspended moveable weights H which can be adjusted in any desired position
and held by notches in the bars G as shewn, or by other equivalent means.
Or as
shewn in figure 3, the weights H may be suspended by forks L to moveable frames K
having wheels which move upon the guides I carried by the arms D, and can be
adjusted in any desired position by means of the rope M, the ends of which hang
down on both sides within reach of the persons in the two cars, who can thus exactly
balance their weights.
The angular revolving and oscillating beam D may be provided with suitable wind
vanes or hollow hemispheres N, (figure 3) by which the apparatus is made to revolve
by the action of the wind.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I
claim is :-
:-
The revolving and oscillating angle beam having arms D, D, to which the cars E, E,
are suspended, the beam being carried by the pin C revolving upon the dished
support B on the post A being provided with adjustable weights H, substantially as
and for the purpose described and shewn in the drawing.
