Improvements in the Construction of Cycles.
I, JOSEPH ORME, of 94, Enbridge Street, Broadway, Salford, Commercial Clerk,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of cycles, and has
for its object to provide a construction which can be ridden with greater ease than
is the case with the present arrangement.
In carrying out my invention I propose to make the rear wheel of the bicycle
double, or to employ two separate wheels placed very close together. The frame
of the cycle is modified slightly to suit the altered construction, the rear portion
being made somewhat wider so as to encircle both wheels.
I prefer to place the driving chain of the cycle between the two wheels so as
to drive from the centre the hubs of the wheels being provided with a suitable
chain wheel over which the chain passes. I also propose to employ two
chains and an additional double chain wheel placed between the two ordinary
ones.
The chain from the crank wheel passes over the smaller part of the double
wheel, and the second chain passes from the larger portion over the small chain
wheel on the hub. A double gearing is thus provided allowing a higher gear to
be obtained in a convenient manner.
The cranks are also of special form each being made with an elbow extending
at an acute angle to the main part of the crank and on the extremities of each
crank a pedal is fitted, formed for preference to the shape of the foot. This
form of crank allows increased power to be obtained without giving a large
stroke.
This arrangement of double wheel allows the cycle to stand by itself without
any other support, thus enabling any person to ride it with great ease. At the
same time it is much lighter than the ordinary tricycle being very little heavier
than a safety bicycle.
To secure the parts rigidly and to prevent the front wheel turning, I propose to
fit a small device to the brake which holds it down on the front wheel. This device
consists of a stop fitted to the top of the steering spindle which can be turned
around so as to bear on the upper end of the brake when the latter is pressed
down in to operative position.
The cycle is thus prevented in a simple but efficient manner from moving.

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 the construction of cycles and has for
its object to provide a construction which can be ridden with greater ease, than is
the case with the present arrangement.
In carrying out my invention, I propose to make the rear wheel of the bicycle,
double; or to employ two separate wheels placed very close together. The frame
of the cycle is modified slightly, to suit the altered construction, the rear portion
being made somewhat wider, so as to encircle both wheels.
I prefer to place the driving chain of the cycle, between the two wheels, so as to
drive from the centre: the hubs of the wheels being provided with a suitable chain
wheel, over which the chain passes.
:
I also propose to employ two chains and an additional double chain wheel placed
between the two ordinary ones. The chain from the crank wheel passes over the
smaller part of the double wheel and the second chain passes from the larger
portion over the small chain wheel, on the hub: double gearing is thus provided,
allowing a higher gear to be obtained in a convenient manner:-Fig. 1. The
cranks are also of special form each being made with an elbow extending at an
acute angle to the main part of the crank and on the extremities of each crank
the usual shape of pedal is fitted. This form of crank allows increased power to be
obtained, in pedaling without the rider having to give a large stroke by the feet.

The arrangement of double wheels allows the cycle to stand by itself, without
any other support, thus enabling any person to ride it with great ease, at the same
time it is much lighter than the ordinary tricycle being very little heavier than a
safety bicycle.
:
To secure the parts rigidly, and to prevent the front wheel turning, I propose to fit
a small device over the brake rod, which will hold it firmly down on the front wheel:
whilst the machine is stationary. This device consists of a loose adjustable stop
fitted to the top of the steering spindle, which can be turned around by the fingers,
and thumb, so as to bear on the upper end of the brake rod, when the brake is
pressed down into operative position:-Fig. 3. The cycle is thus prevented, when
necessary, in a simple but efficient manner from moving.
Having now particularly described, and ascertained the nature of my said in-
vention, and in what manner the same is to be performed: I declare that what I
claim is :-
.
1. The new shape of frame.
2. The new position of the two hind wheels.
3. The new position, and system of chains; and driving wheels.
4. The new shape of cranks.
5. The stop to secure the brake, as previously described.
