Year: 1861

page_text: LETTERS PATENT to Henry James Rouse, of Alexandria, Egypt, 'Civil
Engineer, for the Invention of "AN IMPROVEMENT IN HAND LAMPS."
Sealed the 20th December 1861, and dated the 28th June 1861.
PROVISIONAL SPECIFICATION left by the said Henry James Rouse at
the Office of the Commissioners of Patents, with his Petition, on
the 28th June 1861.
I, HENRY JAMES ROUSE, of Alexandria, Egypt, Civil Engineer, do hereby
5 declare the nature of the said Invention for "AN IMPROVEMENT IN HAND
LAMPS," to be as follows:-
My Invention refers to those hand lamps in which colored glasses are placed
capable of being revolved to show a different color for signalling purposes.
My Invention consists in carrying a ring, a stud, or other appliance con-
nected to the frame in which the colored glasses are fitted through the
bottom of the lamp frame in order that the turning of the glasses may be
effected from the bottom of the lamp frame. A shield in the form of a deep
ring protects the appliance for turning the glasses, and at the same time
forms a stand for the lamp to rest upon when not carried.
15 SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry James Rouse in the Great Seal Patent Office on
the 28th December 1861.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of June, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry James Rouse, Her special licence that I, the said Henry
James Rouse, my executors, administrators, and assigns, or such others as I,
the said Henry James Rouse, 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 "AN IMPROVEMENT IN HAND LAMPS," upon the condition (amongst others)
that I, the said Henry James Rouse, 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 within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry James Rouse, do hereby declare
the nature of my 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, reference being had to the Drawings hereunto annexed,
that is to say :-
My Invention refers to those hand lamps in which colored glasses are
placed, capable of being revolved to shew a different color for signalling
purposes.
My Invention consists in carrying a ring, a stud, or other appliance con-
nected to the frame in which the colored glasses are fitted through the bottom
of the lamp frame in order that the turning of the glasses may be effected
from the bottom of the lamp frame. A shield in the form of a deep ring
protects the appliance for turning the glasses, and at the same time forms a
stand for the lamp to rest upon when not carried.
Figure 1 of the accompanying Drawings is a front elevation of one of my
hand lamps with the frame carrying the "bulls-eye" open; Figure 2 is a
longitudinal section of the same with the lamp holder and frame, in which the
colored glasses are fitted, removed; Figure 3 is a horizontal section through
the line x, y, of Figure 2; Figure 4 is a front elevation of the lamp holder
and colored glasses' frame, and Figure 5 is a plan of the under side of the same.
The same letters of reference indicate like parts in all the Figures.

page_text: a is the frame carrying the green and red or other colored glasses b, c;
d is a ring fitted with a stud or finger piece e at the bottom of the frame a;
f is the aperture in the bottom of the lamp through which the lower end of
the frame a passes; g is a ring on the under side of the lamp, forming a shield
to the ring d and stud e, and at the same time acting as a stand to the lamp.
There is a spring clasp h for retaining the frame a in any required position
according to the colored light exhibited. The lamp itself is also fitted with all
the other requisite appliances common to hand lamps generally. By pressing
back the spring at the back of the lamp the frame a may be turned as required
by means of the stud e at bottom; on releasing the spring a pin connected to
it enters a hole in the back of the frame a, and secures the latter.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim as my
"Improvement in Hand Lamps," fixing a ring, stud, or other like appliance
to the bottom of the frame carrying the colored glasses, and extending the
same through the bottom of the lamp frame for the purpose herein-before
described.
In witness whereof, I, the said Henry James Rouse, have hereunto
set my hand and seal, this Tenth day of December, One thousand eight
hundred and sixty-one.
