Southampton and GEORGE HAYWARD STREET Licentate of the Royal College of
Surgeons in Dental Surgery, 3 Hill Rise Richmond Surrey, do hereby declare the
nature of our invention for IMPROVEMENTS IN HYDRAULIC MOTORS AS DESCRIBED
IN HEADING TOGETHER WITH THEIR APPLICATION 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 our invention is to obtain a peculiar adapted motor for the purpose
of driving or propelling machines of various kinds, and we propose to illustrate its
principles by its application to Tricycles.
On the treadle shaft of the ordinary arranged machine we purpose placing two
eccentrics which give motion to two pumps which we call the pressure pumps-The
discharge from these pumps we lead to an accumulator, which accumulator is a
hollow Cylinder having a packed piston and a powerful spring is placed against
this piston and finds its pressure from a cover at the other end of the Accumulator :-
We then lead the water or other fluid from this accumulator to specially devised
rams through ordinary slide valves or their equivalents, the heads of the rams have
each of them a roller in them which presses against an eccentric, cam, or crank,
according to arrangement which in its revolution caused by each ram pressing in
its turn, moves a mitré or bevel wheel attached to it which mitre or bevel wheel,
gearing with a companion wheel on the main shaft of the tricycle turns the wheels,
the exhaust fluid from the rams we lead back again to a tank from which the
pressure pumps take their supply, In order that we may better illustrate our
invention we propose to describe the same by figures marked on our drawings and
to further define those figures.
In fig: 3 No 1 we call the eccentrics & straps driving by the rotation of the
treadles the pumps N° 2.
In fig 1. No 3 is the accumulator and in fig 4 is shown as a hollow Cyl having
a packed piston A and a spring marked B, C is a cover screwed into the
accumulator Cyl and the spring further rests against it, D is a cover also screwed
into Cylr and has a spigot E forming part of it which prevents the piston from
passing the passages F, F.

page_text: In fig 1, 2, 3, No 4, 4, 4, are the Cylrs or casings containing the slide valves or
their equivalents, and the rams, No 5, 5, 5, are the rams, and 5a are the rollers in
the head of each ram. No 6 in this particular case is a cam or eccentric but a
crank can also be used.
In fig 3. No 7 & 8, are the wheels for communicating the motion, imparted to 5
the cam, to the main shaft 9.
In fig 1. No 10, 10, are the wheels of the machine.
In fig 1 & 2, No 11 is the tank or reservoir for the fluid.
In fig 4 we specially make an attachment to the ordinary glands which we
consider does away with side guides and which we fit to all glands in our motor 1
and which we thus describe N° 13, 13, are steel rollers secured between two
lugs, 14, 14, cast on the projecting part of the gland these rollers are kept in their
positions by through bolts and are free to revolve when the ram in passage to & fro
in its work touches them, thus reducing friction to its minimum.
Having now particularly described and ascertained the nature of our said 1
invention and in what manner the same is to be performed, we declare that what
we claim is
Firstly. The construction of the motor substantially as described.
Second. The form of our Accumulator and its attachments.
Thirdly. The special atttachment to the glands of the rollers substantially as 2
described.
