1, EDWARD LEAMY of 194 Grape Street, Syracuse in the State of New York,
United States of America, Manager, do hereby declare the nature of this invention
to be as follows :-
:-
This invention relates to a method of driving or actuating revolving trapeze
instead of by the ordinary method hitherto adopted, the motive power I employ
for the purpose being produced by the aid of a bicycle or other cycle of suitable.
kind.
To effect the object I have in view 1 carry upon the frame of the trapeze from
the revolving centre of same, suitable rods which support at a certain height the
bicycle or other cycle, and upon which the cycle works.
Connected to the frame of the trapeze at a suitable point are pinion and gear
wheels which work in connection with bevilled wheels by means of chains and
having a crank motion.
These chains, wheels etc. are in connection with the driving or treadle action of
the machine.
Thus when the cycle is being worked the connection between it and the trapeze
gives the necessary motive power whereby the trapeze can be revolved.
The speed is capable of being varied by alteration of the action wheels.

COMPLETE SPECIFICATION,
Certain Improvements in or relating to Revolving Trapeze and the
Motive Power to be Employed for Revolving or Actuating the
same, also applicable for analogous purposes.
I, EDWARD LEAMY of 194 Grape Street Syracuse in the State of New York
in the United States of America, Manager, 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, reference being had to
the drawings hereunto annexed and to the letters and figures shewn thereon :-
My invention relates to a method of driving or actuating revolving trapeze and
consists of employing a bicycle or other cycle for the production of the motive
power for actuating the trapeze instead of driving the same by the ordinary method
hitherto adopted.
By my improvements a very effectual method is obtained for creating the motive
power and an effective and pleasing addition is given to the trapeze whereby a
greatly enhanced effect is produced.
Figure 1, Sheet 1, is a view of the trapeze in a vertical position, and shewing the
position of the bicycle.
Figures 2, 3 and 4, Sheet 2, are the different portions of the driving apparatus.
Similar letters of reference relate to similar parts on all the figures.
A is the revolving trapeze turning upon its centre B, C are extra strengthening
rods at the sides or frame of the trapeze, D are the horizontal ends of the trapeze
upon which the horizontal bars and ropes E, E' are attached, F are weighted balls

page_text: upon the frame of the trapeze to assist in balancing same, G are the vertical side
rod supports with additional strengthening rods G, these vertical rods are carried
upwards as shewn in connection with the horizontal rod H upon which the bicycle
is supported.
Hare additonal rods above and below the main horizontal rod H for the purpose
of strengthening same.
The whole framework of the apparatus is suitably suspended by strong rods stays
or chains I and is kept in position and prevented from swaying about also further
strengthened by means of side ropes or bars J.
It will be observed that the bicycle is supported upon the horizontal rod H of the
framework of the trapeze by strong vertical supports or stays K K', also by a
support or stay K'near the centre of the machine. The stays K, K' Kare secured
to the horizontal rod H in any suitable manner and those marked K, K' are con-
nected to the axles of the wheels of the bicycle K² being connected to the machine
as shewn the wheels being kept clear of every impediment so that they may freely
revolve.
A spur or chain wheel L is situated at a convenient point upon the horizontal
rod H in direct connection with the gearing of the bicycle and to this wheel L the
motion is imparted from the bicycle by a driving chain in connection with suitable
gear wheels etc. upon the machine.
In order to clearly understand how the motive power is transmitted and operates
in revolving the trapeze, I will now describe the positions of the various parts seen
in the figures on Sheet 2, of the accompanying drawings and their connection with
each other and with the bicycle and trapeze.
The bicycle occupying the position shewn as before stated a chain wheel L is
connected to any convenient point upon the horizontal rod H.
Parallel with this chain wheel L and upon the axle of same is a mitre bevel
wheel N Figures 3 and 4 this mitre bevel wheel gears into a corresponding mitre
wheel N¹ upon a short horizontal shaft M Figure 3 supported by brackets from the
main horizontal rod H.
This shaft M has a second mitre wheel N which in turn gears with a corre-
sponding mitre bevel wheel N³ situated at the upper end of a vertical driving
shaft O, Figure 2. This driving shaft has upon its lower end a coarse thread P
into which gears a cog wheel P₁ connected with the centre or axle of the revolving
double trapeze.
The gearing P, P¹, shewn in Figure 2, in connection with the centre of the
revolving double trapeze may be "cased in" if required so that no impediment or
otherwise may become entangled with the same in working.
The several parts of the apparatus being in position and constructed as above
described.
The action is as follows,
The rider upon the bicycle commences treadling the motive power is thus
imparted from the machine by means of the chains (a) gear wheels (b) etc. to the
fixed driving wheel L, on the main horizontal rod H thus rotating or actuating the
pairs of mitre bevel wheels N, N' and the short horizontal rod, Figures 3 and 4 in
connection with the mitre bevel wheels N' N³ Figure 2, and the vertical driving
shaft O. This driving shaft being in direct communication with the gearing which
actuates the revolving double trapeze, at its centre as seen in Figure 2. The
motive power being thus transmitted the trapeze is thereby caused to revolve the
speed being governed by the rate the bicycle is driven or worked or by alteration of
the action wheels.
The apparatus having been started additional impetus is given to the revolving
double trapeze, by the performers on each of the horizontal bars E E¹ thereby
considerably diminishing the work of the rider of the bicycle.
Various methods and details of construction may be adopted for transmitting the
motive power to the trapeze but the general arrangement consisting of the chains
gearing and rods or shafts as shewn will probably be found to supply what is

page_text: required. I may mention that I can when desired dispense with the wheels of the
cycle and operate the trapeze in a similar manner to that herein specified.
I wish it to be understood that I do not confine myself to the more precise
details of construction as herein set forth as I may sometimes vary the same to suit
different requirements.
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,
Firstly. The method of utilizing a bicycle or other cycle in connection with
revolving double trapeze as a means for producing the necessary motive power in
order to revolve or actuate the trapeze substantially as herein more fully specified
and described.
Secondly. The manner in which I mount the bicycle in connection with the
trapeze and the introduction and use of the various gear wheels mitre wheels,
driving shafts and rods, forming the working parts of the apparatus or any mere
equivalents thereof, substantially as herein more fully set forth and described.
Thirdly. I claim generally, the various improvements in or relating to revolving
double trapeze and the motive power to be employed for revolving or actuating such
trapeze, substantially as herein set forth and specified.
