Monmouth, Civil Engineer, for an Invention of "AN IMPROVED ARRANGEMENT
AND COMBINATION OF APPARATUS FOR LIGHTING RAILWAY AND OTHER
CARRIAGES BY ELECTRICITY."
PROVISIONAL SPECIFICATION left by the said Richard Laybourne at the
Office of the Commissioners of Patents on the 5th December 1881.

"AN IMPROVED ARRANGEMENT AND COMBINATION OF APPARATUS FOR LIGHTING
RAILWAY AND OTHER CARRIAGES BY ELECTRICITY."
This Invention relates to an improved arrangement and combination of apparatus`
employed for lighting railway and other carriages and trains by electricity.
For this purpose I mount or affix a dynamo electric machine so that it may be
driven by the wheels or axles of the engine, tender, or carriage of a train or other
vehicle by means of bands or straps and pulleys, or by toothed wbcels, or by
friction pulleys actuated by the tyres of the wheels, or by other motive power
carried thereon, the current of electricity derived from such dinamo electric
machine being employed to charge or maintain the force of a series of Faure's
accumulator batteries (or any other suitable accumulator capablo of storing
electricity), such accumulator being carried by the train or carriage.

"AN IMPROVED ARRANGEMENT AND COMBINATION OF APPARATUS FOR LIGHTING
RAILWAY AND OTHER CARRIAGES BY ELECTRICITY."
This Invention relates to. improvements in the means and apparatus employed
for lighting railway and other carriages and trains by electricity.
For this purpose I mount or affix a dynamo electric machine so that it may be
driven by the wheels or axles of the engine, tender, or carriage of a train or other
vehicle by means of hands or straps and pulleys, or by toothed wheels, or by
friction pulleys actuated by the tyres of the wheels, or by other motive power
carried thereon or with the train, the current of electricity derived from such
dynamo electric machine being employed to charge or maintain the force of a
series of Faure's accumulator batteries (or any other suitable accumulator capable
of storing electricity), such accumulator being carried by the train or carriage for
lighting the same by electricity.
In carrying out my Invention I mount or otherwise affix and combine by
suitable mechanism a dynamo or magneto electric machine (for generating electric
currents) to the engine, tender, or carriage, or any other moving vehicle, so that it
may be driven by their respective wheels or their axles, or by an additional wheel
running upon the road or rail; and bands, straps, and pulleys may be used to
transmit the motion to the dynamo machine, or I drive the dynamo machine by
toothed wheels or by friction pulleys actuated by the tyres of the wheels or axles,
or in any other convenient manner, such as by an auxiliary engine supplied with
steam from the locomotivo boiler, or by compressed air. The current of electricity
generated by the dynamo machine is conducted to and charges one or a series of
secondary or storage batteries arranged in combination with the dynamo machine,
for example, the "Faure" accumulators, and from thence the current of electricity
passes away by the conducting wires to the electric lamps in the various parts of
the carriage or train.
It is obvious that when frictional or equivalent gearing transmits the power to
the dynamo machine that when the carriage or train stops the dynamo machine
would be inactive, but by the employment of the aforesaid secondary batteries
sufficient electricity is stored and given off to allow for any stoppage of the train
without causing any cessation of the light.
And in order that my Invention may be more fully understood and readily
carried into effect, I will proceed to describe the same with reference to the
accompanying Drawings.
Figure 1 is a sectional elevation of a carriage fitted with a dynamo machine and
secondary batteries.
A, A, A, are the wheels of the carriage. The motion is transmitted from a
pulley A¹ on one of the carriage axles to the pulleys B on the axis of the dynamo
machine C. On the return journey this belt is put out of gear, and the cross belt
put in gear simultaneously to drive the dynamo machine in the right direction.
The currents are taken from the dynamo inachine by a commutator in the usual
mauner, and conducted to the secondary batteries D, being stored therein and
distributed throughout the train or carriage at the option of the engineer, guard,
or conductor.
In some cases I affix a small dynamo machine in each carriage, which with its
accumulators is complete in itself. When these means are employed, and it is

page_text: desired to light the lamps, the frictional or other wheels are brought into gear by
an arrangement of levers, or by creating a vacuum, or by admitting steam in a
manner similar to the brake mechanism.
Figure 2 shows another modification where the rotary motion from the carriage
or other wheel A is imparted to the dynamo machine C by an intermediate friction
wheel B', which is secured to one end of a bell crank lever c, which is pivotted on
the axis of the dynamo machine C, and insulated therefrom. At the other end of
this lever c there is an adjusting device E, and by turning of the hand wheel B' is
put in or out of gear at will. Figure 2 shows the friction wheel B' in gear with a
wheel B on the carriage wheel axle. Figure 3 is a plan of the arrangement of
apparatus previously described.
When a carriage is not turned at the end of the journey, on its return the
dynamo machine would rotate in the opposite or wrong direction; but Figure 4
shows how I reverse the motion by mounting two dynamo machines on the carriage,
either of which can be put in gear as desired, and according to the direction in
which the carriage is going. Figure 5 is a plan of this arrangement.
A, A, are
the wheels; C, the dynamo machine; and B, B, the friction wheels which are
put in gear advantageously by friction clutches F, F; D, D, are the secondary
batteries mounted in the pit or box G.
In some cases I pivot the dynamo machine in such a manner that it can be
turned when the friction wheel will come in contact with and be driven by the
wheel on the opposite side, and thus cause it to rotate in the right or proper
direction for the return journey.
Having thus described the nature of my Invention, I would remark that I do
not claim any improvement either in tho construction of a dynamo electric
machine, or in the arrangement or construction of Faure's accumulator battery (or
any other accumulator capable of storing up electricity) when used separately, or
for any other purpose than that hereinbefore described.
But what I claim is the arrangement, combination, and application of a dynamo
electric machine (or its equivalent for generating a current of electricity) mounted
upon and driven by the wheels or axles of an engine, tender, or carriage of a train
or other vehicle (or actuated by other motive power carried thereon or therewith)
for charging or maintaining the force of a series of Faure's batteries (or any other
suitable accumulator capable of storing electricity), such accumulator of electricity
being carried by or with the train or carriage for lighting the same by electricity,
substantially as and for the purpose herein described and illustrated respectively by
Figures 1, 24, 3, 4, and 5 of the Drawings hereto annexed, which shew various
modifications of the combinations which respectively constituto my Invention.
In witness whereof, I, the said Richard Laybourne, have hereunto set my
hand and seal, this Fifth day of June, in the year of our Lord Ono
thousand eight hundred and eighty two.
