PROVISIONAL SPECIFICATION.
Improvements in Bicycles, Tricycles, and other Velocipedes.
I THOMAS HANCOCK of 20 Broad Street Worcester in the County of Worcester
Draper do hereby declare the nature of this invention to be as follows:-
In carrying out my invention I fix upon the driving axle a pair of ratchet-wheels,
and in a suitable place I fix a pair of pulleys each one to work in a line with one of
the ratchet-wheels, I also fix in a suitable place a single pulley to work at right-angles
with the ratchet-wheels.
The treadles I place to work vertically from the pair of pulleys, from one of the
treadles I carry a chain, band or rope over a pulley, round a drum connected with
each ratchet-wheel and the other pulleys to the other treadle, each part so arranged
that when pressure is put upon one treadle the axle will revolve and the opposite
treadle be raised.

COMPLETE SPECIFICATION.
Improvements in Bicycles, Tricycles, and other Velocipedes.
I THOMAS HANCOCK 20 Broad Street Worcester in the County of Worcester
Draper 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 bicycles, tricycles and other velocipedes
and has for its object to enable anyone riding or driving a machine of such description
to more effectually use their powers in propelling the said machine and in order that
my invention may be properly understood I now proceed more particularly to set
forth the system, inode or manner in or under which the same is or may be used or
practically carried into effect, reference being had to the annexed sheet of drawings.
Fig. 1 represents a plan of apparatus or machine for propelling bicycles, tricycles
and other velocipedes constructed or arranged according to my invention, and Fig. 2
is a side elevation of the same.
It consists of a pair of ratchet-pulleys or pulleys having ratchet actions or move-
ments, A, A 1, or pulleys having similar actions or movements placed or fixed upon
the driving-axle or the driving-wheel, and in a suitable place a pair of pulleys B, B 1
each to work in a direct line with one of the ratchet-pulleys, also in a suitable place a
pulley C, to work at right-angles with ratchet-pulleys A, A 1. The treadles D I place
to work vertically from pulleys B, B1 from one of the treadles I carry a rope, chain
or band E, over and round the pulleys and ratchet-pulleys to the other treadle as
shewn in Fig. 1, or I use two or more ropes, chains or bands to work in the same
way, each part to be so constructed and arranged that when pressure is put upon one
treadle the driving-wheel will revolve and the opposite treadle be raised, the driving-
wheel being kept in motion by pressure being put upon each treadle alternately.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed or carried into effect
I declare that what I claim is
Novelty in the arrangement and employment of the said different parts to form
an apparatus or gear whereby improvements are made in bicycles, tricycles and other
velocipedes.
Deted this 20th day of October 1800.
