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 Twenty-fourth day of August, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Alfred Augustus De Reginald
Hely, Her special licence that I, the said Alfred Augustus De Reginald
Hely, iny executors, administrators, and assigns, or such others as I,
the said Alfred Augustus De Reginald Hely, my executors, adminis-
trators, 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 Chan-
nel Islands, and Isle of Man, an Invention for "CERTAIN IMPROVE-
MENTS APPLICABLE TO SHADES OR CHIMNEYS FOR LAMPS, GAS AND OTHER
BURNERS," проп
the condition (amongst others) that I, the said Alfred
Augustus De Reginald Hely, by an instrument in writing under my
hand and seal, 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 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: My Invention consists in producing colored effects from the light
emitted by lamps, gas and other burners, through the agency of certain
processes and arrangements in combination with the shades or chimneys
of glass, or other transparent or translucent material, which serve to
protect and regulate the said light.
For the purposes of the colored effects aforesaid, I mean white and
black to be considered as colors; the former obtained from transparent
and translucent, the latter from opaque, surfaces.
My processes and arrangements are as follows, namely, insertion,
application, and screening.
By the first, namely, insertion, I insert and secure in suitably shaped
apertures formed in the plane, convex, or concave surfaces of such glass
or other transparent or translucent shades or chimneys (either at the
time of manufacture or afterwards,) corresponding outlined plane,
convex, or concave pieces of case body or surface-colored glass, or
other transparent or translucent material, of one or more colors,
forming of themselves (by being blown, moulded, or cut), or having
produced upon them (by cutting, engraving, or embossing), any desired
letters, figures, devices, or designs.
Fig. 1, of the Drawings represents a shade of clear glass, with a
circular shaped aperture in its convex surface; Fig. 14, is a corres-
ponding outlined convex "insertion" of surface-colored glass; Fig. 2,
represents the said shade with the said "insertion" secured therein
with any hard clear gum or cement, & ornamented, as the case may
be, with a device engraved upon it, exhibiting a clear effect upon a
colored ground. Such "insertion" may, however, also exhibit a colored
effect upon a clear ground; and finally, more "insertions" than one of
more shapes, sizes, and colors, and exhibiting more designs than one,
may likewise be used upon the same shade.
By the second, namely, "application," I secure to the plane, convex,
or concave surfaces of such glass or other transparent or translucent
shades or chimneys, suitably shaped plane, convex, or concave pieces of
ensed body or surface-colored glass, or other transparent or translucent
material, of one or more colors, forming of themselves (by being blown,
moulded, or cut,) or having produced upon them (by cutting, engraving,
or embossing.) any desired letters, figures, devices, or designs.

page_text: Fig: 3, of the Drawings- represents a shade of clear glass with a
concave surface; and Fig. 34, a leaf-shaped concave application-of
body-colored glass. Fig. 4, represents the said shade with the said
"application" sécured. thereto,, with any hard .clear gum or cement,
exhibiting a colored effect upon a clear ground. Such "application'
may, however, also exhibit a clear effect upon a coloured ground; by using
'cased: or surface-colored glass; and, finally, more "applications" than
one of more shapes, sizes, and, colors, and, exhibiting more lesigns
.than one, may likewise be used upon the same shade.
But, in the case of such "applications," whether cased, body, or
surface-colored, having the form of letters and figures before they are
cemented upon such shades or chimneys, I claim, as new and original,
such only. as have a convex or concave surface; plane-surfaced colored glass
letters and figures cemented, to plane grounds being already in existence.
By the third, namely, "screening," I suspend or support before the
plane, convex, or concave surfaces of such glass or other transparent
or. translucent shades or chimneys, suitably-shaped plane, convex, or
concave pieces of cased, body, or surface-colored glass, or other trans-
parent or translucent material, of one or more, colors,,, forming of
themselves (by being blown, moulded, or cut), or having produced-upon
them (by cutting, engraving, or embossing),,any desired letters, figures,
devices, or designs.
"
This object is effected by means of the arrangement illustrated by
Fig. 5, of the Drawings, which exhibits a small curved. branch A,
proceeding from, and of the same material as the main pipe or
bracket B, which supplies the flame. One end of this branch forming.
a ring C, fits over the thread round the top of the said main pipe or
bracket, upon which the support D, carrying, the clear glass shade is
screwed, confining the branch, but not so tightly as to prevent it from.
being made to revolve with moderate pressure round the burner. The
other end of the branch is supplied with a "nip "E, being a curved
groove or socket for the oval-shaped plane "screen" of surface-colored
glass Fig. 5, to stand in. This "nip" is composed of two thin
narrow curved pieces of the same material as the branch itself, which
at this end, after having had a thread cut upon it a short distance
down, and a small nut screwed upon the said thread, is split into two

page_text: equal parts, to each of which is soldered one of the curved pieces
forming the said "nip," which evidently contracts or expands accord-
ing as the nut is screwed upwards or downwards.
This branch may be modified in its "nip," curve, and other parts, to
fit any description of "screen," nozzle, or burner, and is the most con-
venient mode of suspending or supporting the "screen" before the
shade; although it might be suspended or supported in other ways,
without prejudice to the novel feature of the "shade-screen," which in
the Drawing is embossed into letters and figures, exhibiting a colored
effect upon a clear ground. Such "screen" may, however, also exhibit
clear effect upon a colored ground; and, finally, more
than
one, of more shapes, sizes, and colors, and exhibiting more designs than
one, may likewise be used before the same shade; and such "screen
may also be used inside instead of outside a shade, wherever cir-
cumstances will admit of the same.
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
Invention, "insertion," "application," and "screening," as herein-before
described, or any mere equivalents thereto, for the purposes aforesaid;
it being understood, that the particular examples exhibited in the
Drawings are merely illustrative of the nature and character of the
Invention, as herein-before set forth.
In witness whereof, I, the said Alfred Augustus De Reginald
Hely, have hereunto set my hand and seal, this Twenty-fourth
day of February, in the year of our Lord One thousand eight
hundred and fifty-four.
