Year: 1852

page_text: LETTERS PATENT to Alfred Augustus De Reginald Hely, of
Cannon Row, Westminster, in the County of Middlesex, Civit
Engineer, for the Invention of "AN IMPROVED SHADE OR CHIMNEY
POR LAMPS, CHANDELIERS, GAS AND OTHER BURNERS."
PROVISIONAL SPECIFICATION left by the said Alfred Augustus
De Reginald Hely at the Office of the Commissioners of Patents,
with his Petition, on the 3rd November 1852.
I, ALFRED AUGUSTUS DE REGINALD HELY, do hereby declare the
nature of the said Invention for "AN IMPROVED SHADE OR CHIMNEY FOR
LAMPS, CHANDELIERS, GAS AND OTHER BURNERS," to be as follows, viz. :—
This Invention consists in coloring or coating a transparent or trans-
lucent glass, or similar vitreous shade or chimney of the ordinary
nature and construction, with one or more bands or patches of glass
or similar vitreous substance of another color or colors, either on the
inner or outer surface of said shade or chimney, so that the said bands
or patches may be etched, engraved, cut, printed, or painted, so as to
exhibit on the transparent or translucid ground the desired device,
figuring, or lettering. The mode of producing said bands or patches
being either by staining, through the agency of heat, or by conting or

page_text: casing glass of one color with a layer of glass of another color or colors,
which may be cut away in parts desired, or printed or painted so as to
produce ornamental effect, or exhibit devices, figures, letters, &c. in
one or more colors
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Augustus De Reginald Hely in the
Great Seal Patent Office on the 3rd May 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
ALFRED AUGUSTUS DE REGINALD HELY, of Cannon Row, Westminster,
in the County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of November, in the year of
our Lord One thousand eight hundred and fifty-two, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Alfred Augustus De Reginald Hely, Her
special licence that I, the said Alfred Augustus De Reginald Hely,
my executors, administrators, and assigns, or such others as I, the
said Alfred Augustus De Reginald Hely, 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 IMPROVED SHADE OR CHIMNEY
FOR LAMPS, CHANDELIERS, GAS AND OTHER BURNERS," upon the condition
(amongst others) that I, the said Alfred Augustus De Reginald Hely,
by an instrument in writing under my hand and seal, should parti-
cularly 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 Alfred Augustus De Reginald
Hely, 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:

page_text: The nature of my said Invention consists in producing upon the
inner or outer surface of a transparent or translucent glass, or similar
vitreous shade or chimney for lamps, chandeliers, gas, and other burners,
one or more patches or bands, or bands and patches, of color or colors,
which patches or bands, or bands and patches, may be etched, embossed,
engraved, cut, impressed, or prepared so as to exhibit any desired
lettering, figures, or devices in a prominent and permanent manner.
Having thus described the nature of the said Invention,. I will now
proceed to describe in what manner the same is to be performed, for
the better understanding whereof I have annexed hereto a Sheet of
Drawings, with explanatory notes thereon, with regard to which I hereby
declare that the same are illustrative merely, and that I do not confine
myself to the precise forms or colors there exhibited.
To avoid confusion and repetition I will now state that by the
term "glass" I mean glass usually so called, and all other vitreous
compounds, transparent or translucent. By the term shade or chimney
I mean globes, moons, lotuses, bells, domes, vases, dishes, consumers,
chimnies, and all other varieties of the article that are or may be used
for the purposes aforesaid. By the term "patches "I mean all figures,
large or small, bounded by straight or curved or straight and curved
outlines. By the term "bands" I mean stripes, garters, tillets, and all
similar straight or curved or straight and curved lines. And with
reference to the Drawings, I intend black to be considered as a color,
and the patches or bands, or bands and patches, depicted upon any one
shade or chimney to be taken wholly, partly, or mingled, as depicted
upon any other. Patches or bands, or bands and patches, of one or more
colors may be produced by the following processes, which I consider the
most economical, permanent, and effective, namely, casing and staining.
By the former, if the shade be blown "open," I deposit on the surface
of the clear glass, whilst in the heated state, a sufficient layer of hot
coloured glass, and blow, spread, press, or fuse until the two glasses
have amalgamated or become fixed one to the other; but if the shade
be "moulded," I first insert a sufficient layer of coloured glass, and then
blow the clear glass out to it, so as to form the said shade with the
said layer firmly united thereto.
By the second process I deposit in the usual way upon the inner or

page_text: outer surface of the shade, or both, after it is blown or moulded,
sufficient mineral or metallic coloring matter, prepared according to
the usual recipes for glass staining or enamelling, and submit the same
to the action of heat in the usual way to "burn in" or fix the said
coloring matter so deposited. After the said colors cased or stained
on have been produced (should they not possess the requisite forms and
sizes) I "cut out" with the usual tools, or "eat away" with the usual
acids, all superfluous color, and 1 "cut out" or "eat away" in like
manner from the colored stratum or strata the requisite lettering,
figures, or devices, so as to insure either a clear effect upon a colored
ground, or a colored effect upon a clear ground.
Having now described the nature of the said Invention, and in what
manner the same is to be performed, I further declare that I am aware
that shades have been manufactured (though very rarely, and chiefly of
foreign manufacture,) composed wholly of colored glass; also of clear
glass, wholly covered with colored glass; also of clear glass, wholly
stained with color; also of clear glass, with flowers and other subjects;
but all these are obviously different from my present Invention.
I claim, therefore, with regard to my said Invention, the production
of a glass shade or chimney for lamps, chandeliers, gas and other
burners, such as herein-before set forth and described, whether by
the processes herein-before directed, or by any mere equivalent for the
same.
In witness whereof, I, the said Alfred Augustus De Reginald
Hely, have hereunto set my hand and seal, this Third day of
May, in the year of our Lord One thousand eight hundred and
fifty-three
ALFRED A. DE R. HELY. (L.B.)
Signed and sealed in
my presence,
F. W. CAMPIN,
Patent Agent, Strand.
