Actuating Mechanism for Velocipedes.
I, WILLIAM WALLIS CRISP, of Theobald's Road, Bloomsbury, London, Inventor,
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 :-
The object of my invention is to provide a simple and easily applied mechanism
for assisting in the propulsion of a velocipede. This I effect by means of two or
more balance weights fitted to the crank axle or crank axles of the machine and a
fly wheel mounted on the frame thereof in any convenient position.
In the accompanying drawings Figures 1. 2 show side and back elevations and
Figure 3 a plan of a tricycle fitted with my invention. Only those parts of the
machine.are shewn which are requisite to illustrate the application of my invention
thereto. Similar letters refer to corresponding parts in all the views.
a. a. are balance weights fastened to the bottom of the treadles of the machine.
By wheel carried in a bracket c fixed to the frame thereof. d endless chain working
over cog wheels e el whereby motion is transmitted to the fly wheel 6 from the
crank axle. f stay rods which serve to strengthen the bracket c. Motion is
imparted to the weights and fly wheel by operating the treadles, and when the
weights have been so actuated, their momentum as they continue to revolve imparts
a continuous impetus to the travel of the machine while the fly wheel & stores up
and transmits the power thus created and utilises it to overcome the dead points on
the cranks. By this means the labor of driving the machine is materially reduced,
and the rider greatly assisted in propelling the same. The degree of power thus
created is governed by the size and number of the weights employed, as the heavier
the weights the greater will be their momentum. A suitable brake is fitted to the
machine whereby the motion of the weights can be retarded or arrested at the will
of the rider.
I do not confine myself to the precise details of construction and arrangement
shewn in the accompanying drawings as it is obvious the same admit of modification
according to the particular class of velocipede to which my invention is adapted.
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 :-
1. In a velocipede fitting two or more balance weights to the crank axle or crank
axles of the machine all substantially as hereinbefore set forth for the purpose
specified.
2. In a velocipede fitting a fly wheel to the frame of the machine in any convenient
position all substantially as hereinbefore set forth for the purpose specified.
3. In a velocipede the combination of two or more balance weights fitted to the
crank axle or crank axles of the machine with a fly wheel mounted on the frame
thereof in any convenient position all substantially as herein before set forth for the
purpose specified.
