Improvements in and connected with Bioyoles.
I GEORGE BAILLIE MAIN, of Springvale Mills, Cowlairs, Glasgow, North
Britain, Oil Manufacturer and Refiner, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object to so construct bicycles as to enable the rider to
operate both wheels in place of only one as at present, and so utilize the power
which is lost, besides exercising the muscles of the arms and minimising the work
of the feet. It also gives increased speed and facilitates the running on hilly
roads.
In carrying my invention into practice I drive the front wheel-the back wheel
being driven in the ordinary manner-by the hands by means of chain, ball, belt or
other suitable gearing, the chain or other gearing being carried from a small wheel
keyed to the axle of the front wheel of the bicycle over a larger wheel keyed to
the upright rod or bar on which the handle is fixed. The motion of the handle
for operating the front wheel may either be circular or the up and down motion as
may be desired.
In place of the chain gearing for operating the front wheel, I may operate it by
means of a crank or cranks provided with a suitable handle or handles.
In place of having the two wheels driven independently as already described
I may so arrange the gearing that the motion of the feet on the pedals will operate
both wheels synchronously, or that in conjunction with or without the use of the
hand wheel as may be found most convenient.
I also provide a guide to prevent the front wheel turning round too far as is
often the case, and so upsetting the machine.

Improvements in and connected with Bicycles.
I, GEORGE BAILLIE MAIN, of Orleans, Pollokshields, in the County of Renfrew,
North Britain, Oil Manufacturer and Refiner, 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 improvements in and connected with bicycles, and has
for its object primarily the imparting to the driving mechanism of the cycle a
meaus whereby the rider is enabled to operate both the front and back wheels
simultaneously or separately, thus giving exercise to the arms as well as the legs at
the will of the cyclist, either as an auxiliary force, or a braking power.
In order that my invention may be properly understood and readily carried
into effect I have hereunto appended an explanatory sheet of drawings in the

page_text: several figures of which corresponding parts are marked with the same letters of
reference.
Figure 1 is a side elevation of a bicycle made in accordance with and constituting
my invention.
Figure 2 is a front view of the same.
Figure 3 is a plan of the handle-bar illustrating the employment of a
supplemental handle-bar, as will be hereinafter explained, the lever or operating
connections not being shown.
In carrying my invention into practice I formn the handle or cross-bar a of the
bicycle A in such a manner that each end thereof terminates with an operating
lever and Or in lien of this arrangement, the two levers band & may be
rigidly connected to the said horizontal bar. The handle or cross-bar a is pivotally
connected to the fork pillar e by the bush d. On either side of this bush d, keyed
to the handle-bar a, are two wypers or short levers eund. To the fork n there is
connected a chain wheel y. The motion necessary for driving this chain wheel is
communicated through the said wyperse and by the connecting rods and i, and
the cranks and, which are keyed to the spindle 1, passing through a bush or
bearing m, which is also utilized for connecting the fork a of the said bicycle A,
thereby dispensing with the necessity for two separate bushes. The said connecting
rods and are so constructed as to enable their length to be adjusted to suit any
required throw of the cranks and A, as will be seen from Figures 1 and 2. The
crank & instead of being constructed as a separate piece, may constitute an integral
part of the said chain wheel g. The power, either for driving or braking
communicated to the said chain wheel g, is transmitted by the chain o to a small
chain wheel mounted on the hub of the front wheel B. The rear wheel C iš
driven in the usual way.
To facilitate the mounting of the rider, or to give rest to the arms, the two
stationary handles and s, mounted on an auxiliary or supplemental bar a', are
employed. Or this supplemental bar a' and handles and may be entirely
dispensed with by placing round the handle or cross-bar a at the points zy, short
lengths of loose tubing which would afford menus of accomplishing the same ends
as fast described, but in a simpler manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be perforined, I declare that what I
claim is :-
1. In cycles, the general arrangement, combination, and operation of the parts
whereby in a simple and efficient manner the front wheel of the machine can be
operated separately or simultaneously with the back wheel, to act either as an
auxiliary force or a braking power, substantially as described and illustrated ou
the accompanying sheet of drawings.
2. In cycles, the supplemental handle to facilitate the mounting of the rider or to
give rest to the arms, substantially as described and illustrated on the accompanying
sheet of drawings.
