PROVISIONAL SPECIFICATION.
Improved Means for Lighting Trains by Electricity.
I DANIEL JONES of Near Factory Pwllywrach Gwaun-cae-gurwen in the
County of Glamorgan Miner do hereby declare the nature of this invention to be
as follows:-
:-
My invention relates to a combination of appliances that will enable a railway
train to generate its own electricity for the electric light for lighting the carriages
and consists of a dynamo fixed to one end of the floor of the guards van and driven
by a belt through a hole in the floor from a pulley (in two halves) attached to one
of the axles of the said van so that when the train is in motion electricity will be
generated. The dynamo will be supplied with a fixed, and loose pulley so as to
enable it to be disconnected when the light is not required. To provide against
stoppages of the train at stations and so on I provide accumulators capable of
storing enough electricity to last for an hour or so at a time. The said
accumulators will be charged by the dynamo when the train is in motion.
1 provide
two conductors along the roofs of the carriages and connect same with a lamp in
each compartment. The ends of the conductors will be made and arranged in such
a way as to connect automatically with each other when the carriages are coupled
and to disconnect when uncoupled. I also provide a switch at both ends of the
conductors so as to enable the circuit to be completed whichever carriage happens
to be the furtherest from the guards van.

COMPLETE SPECIFICATION.
Improved Means for Lighting Trains by Electricity.
I DANIEL JONES of Near Factory Pwllywrach Gwaun-cae-gurwen in the
County of Glamorgan, Miner, 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 a combination of appliances that will enable a railway
train to generate its own electricity for the electric light for lighting the carriages
and consists of a dynamo fixed to one end of the floor of the guards van and driven
by a belt through a hole in the floor from a pulley (in two halves) attached to one of
the axles of the said van so that when the train is in motion electricity will be
generated. The dynamo will be supplied with a fixed and loose pulley so as to
enable it to be disconnected when the light is not required. To provide against
stoppages of the train at stations and so on I provide accumulators capable of
The said
storing enough electricity to last for an hour or so at a time.
accumulators will be charged by the dynamo when the train is in motion. I provide
two conductors along the roofs of the carriages and connect same with a lamp in
each compartment.
The ends of the conductors will be made and arranged in such a way as to
connect automatically with each other when the carriages are coupled and to
disconnect when uncoupled. I also provide a switch at both ends of the conductors
so as to enable the circuit to be completed whichever carriage happens to be the
furthest from the guards van.

page_text: And in order that my said invention may be fully understood I will describe the
same with reference to the accompanying sheet of drawings in which
Fig. 1 shews interior of a guards van fitted so as to supply a train with electric
light, Fig. 2 is plan of floor of said van, Fig. 3 is end view.
Fig. 4 is a view
shewing the position of the contacts q, when the carriages are coupled up. there
being two sets of these (viz. positive + and negative -) to each carriage.
The same letters denote the same parts in all the views, a shews a shunt wound
dynamo fixed to the floor b of the guards van on to the shaft of the dynamo is
keyed a toothed wheel c. this engages (through a hole in floor of waggon) with
another toothed wheel d. keyed on shaft e. working in bearings in bangers f. f.
bolted underneath the flooring b and on the shaft e. are mounted three pullies g. h. i,
9. and i being fast and h. being loose k. is a fork for throwing the bands in and out
of gear.
The dotted lines l. m shew the two bands the belt being crossed.
These bands pass over pulley n. keyed on the axle o. of van and also over
the pulleys g. h and i. p shews flat steel springs to which are connected the
contacts q.
It will be seen that these springs are bent so as to extend beyond the buffers in
order that the contacts q. may be pressed tightly together when the carriages are
coupled up, shews the leads (which are connected to the brass contacts 9) and
s accumulators.
The action is as follows:-
When the carriages are coupled up the spring contacts q. will be pressed tightly
together automatically and upon the train running the dynamo will be worked by
means of the bands 1. m. thus producing the necessary current for lighting the train,
the accumulators s. being charged at same time so as to supply current when the
train is at a standstill or slackens speed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
(1.) The spring contacts p. fitted to the ends of the carriages substantially as set
forth.
(2.) The improved means for lighting trains by electricity substantially as set
forth.
