HENRY BINKO of Queens Road Finsbury Park in the County of Middlesex,
Electrician "IMPROVEMENTS IN ELECTRIC RAILWAYS AND TRAMWAYS AND IN
MEANS OR APPLIANCES TO BE USED IN CONNECTION THEREWITH PARTS OF WHICH
IMPROVEMENTS ARE APPLICABLE TO THE PROPELLING OF VEHICLES ON COMMON
ROADS BY ELECTRO-MOTIVE FORCE
"3
In hauling or propelling vehicles along railways tramways and common roads
by the agency of Electro-motive force it has usually been considered necessary to
employ on the engine or vehicle a dynamo of a size and electro motive power
proportionate to the load to be hauled or propelled and in accordance with the
requirements of the gradients and curves of the track or of the common road
where no rails are employed Now according to one part of my invention I
propose to increase the electro motive force of the dynamo or dynamos constituting
the Electro motor on the locomotive by so arranging the wheels of the additional
vehicle or vehicles hauled as that some or each of them shall collect from one of
the rails or other conductor an additional quantity of electric current which is
conveyed from the vehicle or vehicles hauled by means of conductors to the dynamo
or dynamos on the electro locomotive thereby greatly increasing the power of
the same. When suspended conductors are used as for example on common roads
I employ two or more contact trucks or brushes so as to collect an additional
quantity of electric currents which are conveyed to the dynamo on the locomotive
or in the vehicle itself as above described. With a view to avoid the unpleasant
shock which has hitherto been experienced on disconnecting or on connecting the
current from or with the Electro Locomotive and which is liable to result in
fracture of the machinery I employ a peculiarly arranged resistance between the
dynamo and the switch or other appliance on the Electro Locomotive for making
and breaking contact whereby I am enabled to cut off and to supply the current
and consequently to stop or start the electro locomotive in a gradual manner. The
resistance which I propose to use is submerged in water contained in a liquid tight
closed box or case in order to avoid the heating of the resisting medium. In order
to effect a more perfect insulation of the rails and thereby avoid leakage of the

page_text: current I interpose between the bottom of the rail and each sleeper a layer of
rubber or other good non conductor and I fold the edges of the said non-conductor
over the surface of the foot of the rail so as to more or less envelope the said foot
and allow of the holding spikes being driven into the sleeper without being in
actual contact with the rail a metal plate or washer being interposed between the
head of the spike and the insulating material to avoid cutting. Or when using
chairs I recess those parts which would ordinarily be in contact with the rail and
I insert into the said recesses a piece or pieces of insulating material which are
thus kept in position. Or the chair or support itself may be composed entirely of
any suitable insulating material. To avoid the resistance arising from the formation
of rust on the rails more particularly at the ends thereof and at the parts forming
the joints or fastenings such for example as the fish plates bolts and nuts I propose
to galvanize or otherwise coat such parts or the entire rail itself with any good rust
resisting metal or material.
