IMPROVEMENTS IN APPARATUS FOR SIGNAL AND OTHER LIGHTS FOR RAILWAYS
Year: 1852

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WALTER
MARR BRYDONE, of Boston, in the County of Lincoln, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by IIer
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-second day
of January, One thousand eight hundred and fifty-two, in the fifteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Walter Marr Brydone, my exors, adñññors, and assigns, Ier
especial licence, full power, sole privilege and authority, that I, the said Walter
Marr Brydone, my exors, adiñors, and assigns, or such others as I, the said
Walter Marr Brydone, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of IMPROVEMENTS IN APPARATUS FOR SIGNAL AND OTHER LIGHTS FOR
RAILWAYS;" in which said Letters Patent is contained a proviso that I, the
said Walter Marr Brydone, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,
by an instrument in writing under my hand and seal, to be inrolled in Her
said Majesty's High Court of Chancery within six calendar months next
and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Walter Marr Brydone, do hereby declare that the nature of the said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following description thereof,
reference being had to the Drawings hereunto annexed, and to the figures and
letters marked thereon, that is to say:-
My Invention consists in arranging the parts of lamps used for signal and
other lights in connection with railways, so that the same may be suitable to
receive candles as the illuminating means.
In order that the Invention may
be fully understood, I will proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 show two views of a signal post as is commonly used on
railways, with the lamp adapted to my improvements. Figures 3 and 4 shew
two external views. Figure 5 a section through the line A, B, of Figure 3.
Figure 6 a sectional plan through the line C, D, of Figure 5; and Figure 7
a plan of the under side of the lantern drawn full size. In each of the
Figures the same letters of reference are used to indicate like parts. a is the
socket or tube for the candle, and it is affixed to the ring b, which is formed
into a sort of bayonet joint at its edge, so as to be capable of being passed
partly through the lower part of the lantern, and then by being turned partly
round it will be prevented falling out from the lantern, and there is a bolt c
which will prevent the parts shifting. The arrangement of parts to receive
the candle, as also of the chimney apparatus used therewith, which I prefer
to use, and which is shewn by the Drawing, is that in which the lower part of
the chimney is brought down over the nozel of the lamp below the lower
part of the flame, and the air passage is arranged as was described in respect
to a coach candle lamp in the Specification of a Patent granted to William
Palmer, the 4th day of March, 1842. The direction in which the air flows is
indicated by the arrows in Figure 5. d is the foot or step to receive the
lower end of the candle, and which is forced up by a suitable spring e, as is
well understood. f is the nozel to receive the upper part of the candle;
and is the chimney, the shape of which may be varied. In Figures 1 and 2,
I have shewn the lamp as being supported from the post by the brackets g, h,
and the lantern is of the kind in which clear glasses are used; the lamp does
not revolve, and the different colors to indicate the different signals is obtained
by bringing colored glasses over the faces of the lantern, but this may be
varied, and the lantern may have several colored glasses applied to it, and be
caused to rotate so as to bring the face of the lantern in the direction to give

page_text: the desired signal. And although I have only shewn my improvements as
applied to stationary signal lanterns, I would have it understood that I do
not confine my improvements to such lanterns, and the same may be applied
as caution and other signals at the backs of railway carriages and in other
situations on railways, either for the purpose of giving signal or otherwise,
and will be found very useful for illuminating the interior of railway carriages;
and in applying my improvements to such situations, I prefer to form a
chamber between two compartments of a railway carriage, in which I place
the lantern having my improvements applied thereto; and I form the lantern
with a glass on the two opposite sides, by which the two adjoining compart-
ments of the carriage will be illuminated.
I have not thought it necessary to show a Drawing of this modification, as
the same will only differ in the form of the lantern, which will be readily
adapted according to the taste or convenience of the parties.
Having thus described the nature of the said Invention, I would have it
understood that I do not confine myself to the precise details herein shewn
and described, as the same may be varied. But what I claim is the con-
structing lights for signal and other purposes on railways, so that the same
may be capable of receiving candles as described.
In witness whereof, I, the said Walter Marr Brydone, have hereunto
set my hand and seal, this Twenty-first day of July, in the year of
our Lord One thousand eight hundred and fifty-two.
