County of Warwick, Manager of Works, for the Invention of "IMPROVE-
MENTS IN LAMPS FOR RAILWAY AND OTHER CARRIAGES.
MENTS IN LAMPS FOR RAILWAY AND OTHER CARRIAGES..
Sealed the 16th August 1864, and dated the 22nd February 1864.
PROVISIONAL SPECIFICATION left by the said Frederick Richard Mosley
at the Office of the Commissioners of Patents, with his Petition, on the
22nd February 1864.
I, FREDERICK RICHARD MOSLEY, of Birmingham, in the County of Warwick,
Manager of Works, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LAMPS FOR RAILWAY AND OTHER CARRIAGES," to be as
follows:-
My Invention consists of the improvements herein-after described in the
oil reservoirs of lamps for railway and other carriages, by which improvements
the said lamps are rendered capable of burning with convenience and safety
paraffin oil, petroleum oil, and other volatile oils as well as fixed oils.
I make the oil reservoir by preference of an annular figure, and I fix the
said annular reservoir at the top of the lamp case, and external thereto, the
said reservoir surrounding the top of the lamp, but being isolated therefrom,

page_text: so that there is a free circulation of air between the reservoir and the lamp.
The said annular reservoir is supported on the top of the lamp, and the tubes
by which the oil is conducted to the burner, and the said reservoir and
burner can be removed from and replaced in the lamp case together. Instead
of making the reservoir of a complete annular figure it may be made in the
form of a ring, interrupted or divided at the part where the spring catch
fastening of the lamp is situated, or the reservoir may be made in two parts,
each of the said parts having the figure of portions of a ring.
Although I prefer to give the reservoir, whether in one or two parts, the
general figure of a ring, yet I do not confine myself to that figure, as it may
be made of other forms, the essence of my Invention consisting in making the
reservoir surround or partly surround the upper part of the lamp case.
SPECIFICATION- in pursuance of the-conditions of the Lotters Patent, filed
by the said Frederick Richard Mosley in the Great Seal Patent Office
on the 17th August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
RICHARD MOSLEY, of Birmingham, in the County of Warwick, Manager of
Works, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of February, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Frederick Richard Mosley, Her special licence that I, the said
Frederick Richard Mosley, my executors, administrators, and assigns, or such
others as I, the said Frederick Richard Mosley, 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, use, exercise, and vend, within the United Kingdom..of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN LAMPS FOR RAILWAY AND OTHER CARRIAGES," upon the
condition (amongst others) that I, the said Frederick Richard Mosley, 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 Seal Patent Office

page_text: within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Frederick Richard Mosley, 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:―
My Invention consists of the improvements herein-after described, in the
oil reservoirs of lamps for railway and other carriages, by which said improve-
ments the said lamps are rendered capable of burning with convenience and
safety paraffin oil, petroleum oil, and other volatile oils, as well as fixed oils.
I make the oil reservoir by preference of an annular figure, and I fix the said
annular reservoir at the top of the lamp case, and external thereto, the said
reservoir surrounding the top of the lamp, and being isolated therefrom, so
that there is a free circulation of air between the reservoir and the lamp. The
said annular reservoir is supported on the top of the lamp, the tubes by which
the oil is conducted to the burner being fixed to the said reservoir, and the
said reservoir and burner can be removed from and replaced in the lamp case
together. Instead of making the reservoir of a completo annular figure it
may be made in the form of a ring, interrupted or divided at the part where
the spring catch fastening of the lamp is situated, or opposite the said spring
catch fastening, or the reservoir may be made in two parts, each of the said
parts having the figure of portions of a ring.
Although I prefer to give the reservoir, whether in one or two parts, the
general figure of a ring, yet I do not confine myself to that figure, as it may
be inade of other forms, the essence of my Invention consisting in making the
reservoir surround or partly surround the upper part of the lamp case.
Having explained the nature of my Invention, I will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same.
is to be performed.
Figure 1. represents in side elevation a roof lamp for railway carriages
constructed according to my Invention; Figure 2 is a plan of the same;
Figure 3 is a vertical section of the same; and Figure 4 is a plan of the
same, with the head of the lamp removed. Figure 5 represents in elevation,
and Figure 6 in plan, the oil reservoir, conducting tubes, and burner of the
lamp separately. The same letters of reference are employed to indicate the
same parts in each Figure of the Drawing.
a is the lamp case; b, the glass covering the lower part of the said case;.
and c is the moveable head or upper part of the case, turning on a joint d,<
and being fastened in its place by the spring catch fastening d². The

Conducting tubes f, f, from tho
of the lamp case a, and convey
parts a, b, c, d, and d are of the ordinary construction. Surrounding or
partly surrounding the upper part c of the lamp case, and external thereto,

oil or fixed oil to be burned in the lamp.
annular or nearly annular figure represented.
reservoir e pass through slots a² in the top
the oil to the burner 9, supported by the said tubes f. The reservoir e is
supported on the top of the lamp case by its ends resting on the small
brackets h, and pins or studs i on the bottom of the reservoir entering holes
in the top of the lamp case. When the reservoir e and burner g are in their
place in the lamp case, as represented in Figure 8, they are fixed steadily to
the lamp by the head or part c closing the tops of the slots a², through which
the conducting tubes f pass. The reservoir is supported a short distance from
the exterior of the lamp case, as best seen in Figure 8, so as to isolate it
therefrom, and permit of a free circulation of air between the reservoir and
the lamp.
The said reservoir is thereby kept cool, and the heating and
volatilization of the oil when volatile oil is used thus prevented. The
reservoir, tubes, and burner are removed from and replaced in the lamp case
together. In order to remove the reservoir and burner it is only necessary to
open the head c of the lamp, when the said parts can be lifted from the lamp
case. To replace the reservoir e and burner g the burner is depressed in the
lamp case, the conducting tubes f being dropped into the slots a' at the top of
the case. The ends of the reservoir e are thereby made to rest on the
brackets and the pins i to enter the holes in the lamp case. The head c of
the lamp being closed the several parts are securely fixed in

their places.
Instead of making the reservoir surround about two-thirds only of the
circumference of the upper part of the lamp case, as represented in tho
Drawing, the reservoir may be made to surround the whole of the lamp case;
or the reservoir may be made in two parts, each of the said parts being
portions of a ring.
Although I prefer to give the reservoir the general figure of a ring, or
portions of a ring, as represented in the Drawing, and which form I have
found to be most convenient in use, yet other forms capable of encircling
or partly encircling the upper part of the lamp case may be given to the said
reservoir.
My Invention may be applied to carriage lamps other than roof lamps, such
as head, tail, and side lamps.
Having now described the nature of my Invention, and the manner in

page_text: which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described, as the same may be varied
without departing from the nature of my Invention; but 1 claim as my
Invention the improvements in lamps for railway and other carriages, herein-
before described and illustrated in the accompanying Drawing, that is to say,
making the oil reservoirs of the said lamps surround or partly surround the
exterior of the upper part of the lamp case, the said reservoirs being by
preference isolated from the said lamp case.
In witness whereof, I, the said Frederick Richard Mosley, have here-
unto set my hand and seal, this Fifteenth day of August, in the year
of our Lord One thousand eight hundred and sixty-four.
Witness,
FREDERICK RICHARD MOSLEY. (L.B.)
