page_text: We, GEORGE CAWLEY and BENJAMIN HOWARTH THWAITE, both of 29, Great
George Street, Westminster, Civil Engineer, do hereby declare, the nature of this
invention to be as follows:-
Our invention has for its object to provide a system of haulage specially adapted
for canals or general waterways as well as for land traction, which shall avoid
the use of horses by the utilisation of electric energy, and is an improvement
and extension of our invention for which Letters Patent have been granted to
us (No. 1087, 18th January 1894).
According to our invention the electric locomotive is arranged to travel upon a
rail of special section, which allows of the driving wheels running underneath as
well as on the top of the rail but in different vertical planes. This disposition of
the driving wheels in relation to the rail, forms a kind of lever, or overhang
arrangement, which permits of any pre-arranged pressure being brought upon the
wheel treads, and in this way a much greater tractive effect can be obtained per
unit of weight of locomotive than can be got from locomotives as ordinarily used
on railways.
In connection with our invention we may arrange upon or above the posts or
supports carrying the rails for the electric locomotive, a wire, rope, or light rigid
track which may be used for the conveyance of goods or merchandise of small
weight. These goods would be packed in suitably shaped skips or baskets which
could be easily inserted in or removed from a suspended cage or carrier moved
along the wire or rigid track by a suitably disposed electric motor.

GEO. CAWLEY,
B. H. THWAITE.
We, GEORGE CAWLEY and BENJAMIN HOWARTH THWAITE, both of 29, Great
George Street, Westminster, S.W., in the County of Middlesex, Civil and
Mechanical Engineers, 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:―
Our invention has for its object to provide a system of haulage specially adapted

page_text: for canals or general waterways as well as for land traction, which shall avoid
the use of horses by the utilisation of electrical energy, and is an improvement
and extension of our invention for which Letters Patent have been granted to us
(No. 1087, 18th January 1894).
According to our invention the electric locomotive is arranged to travel upon
a rail of special section, which allows of the driving wheels running underneath as
well as on the top of the rail, but in different vertical planes. This disposition
of the driving wheels in relation to the rail forms a kind of lever, or overhang
arrangement, which permits of any pre-arranged pressure being brought upon the
wheel treads, and in this way a much greater tractive effect can be obtained per
unit of weight of locomotive than can be got from locomotives as ordinarily used
on railways.
In connection with our invention we may arrange upon or above the posts or
supports carrying the rails for the electric locomotive, a wire, rope, or light rigid
track, which may be used for the conveyance of goods or merchandise of small
weight. These goods would be packed in suitably shaped skips or baskets which
could easily be inserted in or removed from a suspended cage or carrier moved
along the wire or rigid track by a suitably disposed electric motor.
And in order that this our invention may be more readily understood and
carried into practical effect we have hereunto appended a sheet of drawings, the
figures thereon being marked with similar letters to denote similar parts.
Fig. 1 is an end elevation and Fig. 2 is a side elevation of the general arrange-
ment of our invention.
For the purpose of adjusting the adhesive pressure to be placed upon the driving
wheels of the locomotive A, we arrange the driving wheels B, so that they stand
in different vertical planes, and the horizontal distance between these planes with
reference to the centre of gravity of the locomotive in its entirety determines the
ratio of the adhesive pressure on the wheels to the simple weight of the locomotive.
For the purpose of carrying out our invention in connection with the conveyance
of goods or mechandise of small weight, we prolong the lengths of the metallic
standards or posts of wood C, used for supporting the metallic beams or rails
carrying our canal haulage locomotives A, and affix to the top of the said posts,
by means of suitably designed brackets D), two light rails E of channel or other
convenient section, which may be supported at intermediate points by suitably
shaped stays or standards. Upon these rails E, are placed light locomotive car-
riages, driven by an electric motor G through spur, bevel, belt or chain
gearing H. Suspended from these locomotive carriages are suitably shapel
cages or carriers for receiving and conveying light goods or merchandise of small
weight.
In order to connect the electric motor G on the locomotive carriage F with
the generating station, a metallic conductor M is affixed to the bottom flange
of the rail by a suitably arranged insulated connection. The current is conveyed
to the motor from the conductor by a wheel, or spring sliding piece or tongue N,
together with suitable conducting wires and controlling accessories.
For the purpose of stopping or starting the locomotive carriage at any required
point, a rope or chain of convenient length may be hung from the switch lever,
or the switch may be operated by a small spindle carrying a turning wheel or
handle.
Where automatic stopping of the locomotive carriage is required, we affix a
sliding projection or stop to the supporting posts C, and such projection may be
operated by a rod and lever placed in a convenient position, or by a suitably
disposed rope or chain. When the locomotive carriage is required to stop near
any supporting post, the sliding projection is pushed forward and by engaging
with the switch lever on the moving locomotive carriage automatically switches
off the current from the motor, and brings about the stoppage of the locomotive
carriage as required,

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
(1) The combination of driving wheels on a locomotive, so disposed that the
adhesive pressure between the wheels and the rail may be increased and varied
to any desired extent by an overhang or lever arrangement, substantially as
described herein and illustrated on the accompanying sheet of drawings.
(2) The combination of an electric method of transportation of light goods along
with our patented method of canal boat electric haulage, substantially as described
herein and illustrated on the accompanying sheet of drawings.
