Improvements in Machinery for Propelling Vehicles by Manual
Power.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 31, High Holborn, in the County of Middlesex,
6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in the County
of Lancaster, and Lower Temple Street, Birmingham, in the County of
Warwick, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to a machine adapted to drive a car or trolley in the
following manner :—
For a tram car a crankshaft with one or more cranks at any desirable angles is
fixed to a certain number of brackets with their respective bushes, the brackets
may be fixed to the bottom of the car or to a soleplate of wood or metal, which
soleplate with brackets and crankshaft may be fixed to the bottom or other part
of the car.
The brackets are to slide for a certain distance on the soleplate,
each bracket having adjustable screws to adjust an appropriate tension on the
platechain.
To the centre or other part of the crankshaft a metal sheave is to be fixed.
This sheave will have a convenient number of studs to carry a platechain. In a
line with this sheave on the axle of the car another sheave is to be fixed also with
studs. The above two sheaves will carry a platechain of adequate size and
strength to perform the work necessary to drive the car.
To each crank a connecting rod is fixed which is connected to a lever resting on
a bracket and plummer blocks at a suitable height above the floor of the car.
The lever will be of such suitable length as to allow of the power being applied
to the crankshaft in the ratio of three to one or such other ratio as may be
suitable.
As before mentioned the sheave on the crankshaft may be of cast iron or any
other metal, as malleable cast, etc. with studs of a required size and strength to
carry a suitable chain. The sheaves on the crankshaft and axle may be fixed in
any suitable manner, by keys and bolts or otherwise, and may be whole or in
halves. The crankshaft may be made in two or more pieces with couplings to
which the big sheave may be attached which will not necessitate the sheave being
cast in halves.
The levers will have an up and down travel of three feet six inches, or other
suitable distance.
The machinery for driving a car as above described may be fixed and arranged
to be worked from either or both ends, or from the roof or other part of the car
and may be placed so that the levers are parallel with the length of the car or in
any other suitable direction.
By this arrangement there may be one man at each end of the car, either of
whom may at any time leave his lever and apply the brake to stop the car when a
bassenger wishes to alight from or enter the car.

page_text: The machinery may also be fixed so as to allow the levers being worked across
the breadth of the car by having a crankshaft with one or more cranks at suitable
angles under the bottom of the car with its necessary brackets and bushes on the
side of the car against the frame work as close as possible to allow the working of
the cranks and connecting rods clear of the frame. This crankshaft to have a
bevel pinion gearing into another bevel pinion fixed on the end of a straight shaft
running across the breadth of the car fixed to its respective brackets in place of
the crankshaft before described. To the centre or other part of this straight shaft
is fixed a sheave with studs which works the sheave on the axle by means of the
platechain. The connecting rods and levers are attached and worked the same as
described in paragraph three.
A trolley is worked exactly on the same principle as a tram car, with the
exception that countershafts and pinions are added so as to multiply the gear to
acquire the required speed.
The power can be transmitted from the crankshaft to the axle of the car by
means of cogwheels in place of the sheaves and platechain before mentioned.

Improvements in Machinery for Propelling Vehicles by Manual
Power.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 322, High Holborn, in the County of Middlesex,
6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in the County
of Lancaster, and Lower Temple Street, Birmingham, in the County of
Warwick, Civil Engineer, 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 a machine adapted to drive a car or trolley in the
following manner :-
For a tram car a crankshaft with one or more cranks at any desirable angle is
fixed to a certain number of brackets with their respective bushes, the brackets
may he fixed to the bottom of the car or to a soleplate of wood or metal, which
soleplate with brackets and crankshaft may be fixed to the bottom or other part
of the car.
The brackets are to slide for a certain distance on the soleplate,
each bracket having adjustable screws to adjust an appropriate tension on the
platechain.
To the centre or other part of the crankshaft a metal sheave is to be fixed.
This sheave will have a convenient. number of studs to carry a platechain. In a
line with this sheave on the axle of the car another sheave is to be fixed also with
studs. The above two sheaves will carry a platechain of adequate size and
strength to perform the work necessary to drive the car.
To each crank a connecting rod is fixed which is connected to a lever resting on
a bracket and plummer blocks at a suitable height above the floor of the car.
The lever will be of such suitable length as to allow of the power being applied
to the crankshaft in the ratio of three to one or such other ratio as may be
suitable.
The sheave on the crankshaft may be of cast iron or any other metal, as
malleable cast iron, etc. with studs of a required size and strength to carry a
suitable chain. The sheaves on the crankshaft and axle may be fixed in any
suitable manner by keys and bolts or otherwise, and may be whole or in halves.

page_text: The crankshaft may be made in two or more pieces with couplings to which
the big sheave may be attached which will not necessitate the sheave being cast
in halves.
The levers will have an up and down travel of three feet six inches, or other
suitable distance.
The machinery for driving a car as above described may be fixed and arranged
to be worked from either or both ends, or from the roof or other part of the car
and may be placed so that the levers are parallel with the length of the car or in
any other suitable direction.
By this arrangement there may be one man at each end of the car, either of
whom may at any time leave his lever and apply the brake to stop the car when a
passenger wishes to alight from or enter the car.
The machinery may also be fixed so as to allow of the levers being worked.
across the breadth of the car, by having a crankshaft with one or more cranks at
suitable angles under the bottom of the car with its necessary brackets and bushes
on the side of the car against the frame work as close as possible to allow the
working of the cranks and connecting rods clear of the frame. This crankshaft to
have a bevel pinion gearing into another bevel pinion fixed on the end of a straight
shaft running across the breadth of the car fixed to its respective brackets in place
of the crankshaft before described. To the centre or other part of this straight
shaft is fixed a sheave with studs which works the sheave on the axle by means of
the plate chain. The connecting rods and levers are attached and worked in the-
manner herein before described.
A trolley is worked exactly on the same principle as a tram car, with the
exception that countershafts and pinions are added so as to multiply the gear to.
acquire the required speed.
The power can be transmitted from the crankshaft to the axle of the car by
means of cogwheels in place of the sheaves and platechain before mentioned.
I will now proceed to describe my invention with reference to the drawing filed
with this Specification, in which two modifications of the same are shewn as
applied to a tram car.
The motive power may be applied either by means of winch handles K or by
hand levers S hinged to connecting bars T and actuating the triple crank shaft A¹
of the sheave A. In either, case the sheave A transmits its motion by means of
the plate chains J to a sheave B attached to another sheave C which may be
connected in the same manner to a sheave F on the axle of the tram wheel M
either directly or by means of intermediate sheaves DE, or the sheave B may be
fastened to a gear wheel C¹ engaging with a gear wheel D on the axle of the tram
wheel M. Both these arrangements are shewn in the drawing.
The axles of the tramcar are preferably supported in bearings L. X is the
supporting frame for the winch or lever respectively.
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:-
The mechanism for propelling vehicles by manual power. substantially as.
herei before described.
