page_text: LETTERS PATENT to Remy Elmsley, of Toronto, Canada, at present
residing at Leamington, in the County of Warwick, for the Inven-
tion of "IMPROVEMENTS IN ELECTRIC COMMUNICATION BETWEEN RAILWAY
TRAINS IN TRANSIT AND STATIONS OR TERMINI, AND IN THE APPARATUS
CONNECTED THEREWITH."
Sealed the 18th July 1873, and dated the 22nd January 1873.
PROVISIONAL SPECIFICATION left by the said Remy Elmsley at the
Office of the Commissioners of Patents, with his Petition, on the
22nd January 1873.
I, REMY ELMSLEY, of Toronto, Canada, at present residing at Lea-
mington, in the County of Warwick, do hereby declare the nature of
my said Invention for “ImproVEMENTS IN ELECTRIC COMMUNICATION BETWEEN
RAILWAY TRAINS IN TRANSIT AND STATIONS OR TERMINI, AND IN THE APPARATUS
CONNECTED THEREWITH," to be as follows:-

page_text: electricity, with persons in authority at stations or termini on the line
of route on which such train or trains may be travelling, or to enable
one train to communicate with another whether travelling or stationary
on the same track.
The improvements consist in providing the permanent way and the
train or carriage travelling upon such permanent way with a peculiar
and novel arrangement of electric apparatus, which may be thus
described. An electric wire is supported parallel with the line of rail
upon insulator supports in a position that will admit of one or more
grooved metallic bowls, rollers, or pullies, each ono secured independently
by universal or other equivalent yielding joints and arms, to the guards'
van to run upon it; the yielding joints in combination with the groove
of the pulley or pullies when the same are resting upon the wire enables
such pullics and their supporting wire whilst the train is in motion to
maintain a perfect and continuous contact. The object of two pullies
being employed and each one working independently of the other is that
there will be always one of them in contact with the wire, for example,
at the time the carriage to which the pullies are attached is passing the
brackets or supports upholding the wire, one of them will maintain an
electric contact therewith, whilst the other is mounting over the insulator
supports. These pullies so connected with the guards' van or other
convenient portion of the train are in direct electric communication
through the medium of a wire with an electric apparatus in the van or
carriage of the railway train, and so through the peripherial revolving or
running portion of the pullies and the parallel supporting electric wire
communication is established direct from the van of the train, whether
standing or running, with any station or termini upon the line of route,
or with any other train or trains on the same track, or vice versa. A
lever in the guard's van or to any other portion of the train to which
the pulley or pullics are attached is in contact through the medium of a
a connecting rod with the adjustable rising and falling axle of such
pullies, which may be actuated by hand or by a tappet, and incline upon
the line in such a manner that when the train is running over junction
points of the line or at the "switches" the said pullics may or will be
raised so as to escape any wire diverging from the parallel course of 3
the train to which such pullies are attached, or the pullics at such
points may be raised so as to escape the diverging lines by other
equivalent means.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, REMY
5 ELMSLEY, of Toronto, Canada, at present residing at Leamington, in the
County of Warwick, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Hor
Letters Patent, bearing date the Twenty-second day of January, in the
year of our Lord One thousand eight hundred and seventy-three, in the
› thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, tho said Remy Elmsley, Her special
license that I, the said Remy Elmsley, exccutors, administrators, and
assigns, or such others as I, the said Romy Elmsley, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, usc, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN ELECTRIC
COMMUNICATION BETWEEN RAILWAY TRAINS IN TRANSIT AND STATIONS OR TERMINI,
AND IN THE APPARATUS CONNECTED THEREWITH," upon the condition (amongst
others) that I, the said Remy Elmsley, my executors or administrators,
by an instrument in writing, under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Scal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Remy Elmsley, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
The Invention is designed for the purpose of enabling the conductors
of a railway train or carriage to communicate through the medium of
electricity with persons in authority at stations or termini on the linc
of route on which such train or trains may be travelling, or to enable
onc train to communicate with another whether travelling or stationary
on the same track.

page_text: The improvements consist in providing the permanent way and the
train or carriage travelling upon such permanent way with a peculiar
and novel arrangement of electric apparatus, which may be thus
described. An electric wire is supported parallel with the line of rail
upon insulator supports in a position that will admit of one or more a
grooved metallic bowls, rollers, or pullies, each one secured independently
by universal or other equivalent yielding joints and arms to tho guard's
van, to run upon it; the yielding joints in combination with the groove
of the pulley or pullies when the same are resting upon the wire enables
such pullies and their supporting wire whilst the train is in motion to:
maintain a perfect and continuous contact. The object of two pullics
being employed and cach one working independently of the other is that
there will be always one of them in contact with the wire, for example,
at the time the carriage to which the pullics are attached is passing the
brackets or supports upholding the wire one of them will maintain an
electric contact therewith, whilst the other is mounting over the insulator
supports. These pullics so connected with the guard's van or other
convenient portion of the train are in direct clectric communication
through the medium of a wire with an electric apparatus in the van or
carriage of the railway train, and so through the peripherial revolving
or running portion of the pullics and the parallel supporting electric
wire communication is established direct from the van of the train
whether standing or running with any station or terminus upon the line
of route, or with any other train or trains on the same track, or vice
versa. A lever in the guard's van or to any other portion of the train
to which the pulley or pullics are attached is in contact through the
medium of a connecting rod with the adjustable rising and falling axle
of such pullies, which may be actuated by hand or by a tappet, and
incline upon the line in such a manner that when the train is running
over junction points of the line or at the "switches" the said pullics
may or will be raised so as to escape any wire diverging from the
parallel course of the train to which such pullics are attached, or the
pullics at such points may be raised so as to escape the diverging lines
by other equivalent means.

page_text: Fig. 1 represents a front elevation of an ordinary railway carriage
having applied thereto the electric apparatus and medium employed for
commucating messages whilst in motion or otherwise. Fig. 2 represents
an end clevation of the same.
In these Figures A, A, is a carriage forming a portion of an ordinary
railway train, in which is placed an electric apparatus a, which may
be of any approved form or construction employed for transmitting
messages. The poles of the battery a¹, a¹, are connected by means of
insulated wires with the peripheries of the running wheels b, b. These
wheels, bowls, or pullies are provided with deep grooves, and are sup-
ported by arms c projecting from the carriage, and are so arranged that
when the bowls are resting or running upon the wire d they will
accomodate themselves to the varying and undulating distances and
positions of such wire. The wire d is supported by insulating brackets
secured to the poles in a position parallel with the permanent way of
the railway, so that during the time the wheels, bowls, or "pullies b, b,
are resting or running on such wire an electrical contact will be
maintained between them. These pullics b, b, when supported by the
wire d arc in direct electric communication through the medium of the
wire a¹ with the electric apparatus in the van or carriage A, and so
through the peripherial revolving or running portion of the pullics 6 to
the parallel supporting clectric wire d, communication is thus established
direct from the van of the train whether standing or running with any
of the stations or termini upon the line of route, or with any other train
or trains on the same track, or vice versa.
Having now described the nature of my said Invention, together with
the method of carrying the same into practical effect, I would wish it to
be distinctly understood in conclusion that I do not confine myself to
the precise details shown and described so long as the essential features
of the Invention arc retained, as there may be various constructions and
modifications of the same without departing from the true meaning and
intent thereof. I claim therefore as my Invention the novel and peculiar
adaptation to railway carriages of the employment and use of apparata,
whereby I am enabled to establish electric communication between one
train and another on a line of route on which such train or trains may
be travelling, or between a train, whether in motion or standing, and
station or termini on such line, in the manner and for the purpose as

page_text: herein substantially described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, I, the said Remy Elmsley, have hereunto sct
my hand and scal, this Tenth day of July, in the year of our
Lord One thousand eight hundred and seventy-three.
