Year: 1864

page_text: LETTERS PATENT to Auguste Clavel, Merchant, of 51, Rue de Malte,
Paris, in the Empire of France, for the Invention of "AN IMPROVEMENT
IN THE MEANS OF HOLDING OR SUPPORTING GLASSES, SHADES, AND REFLECTORS
USED WITH LAMPS AND BURNERS."
Sealed the 13th April 1865, and dated the 19th October 1864.
PROVISIONAL SPECIFICATION left by the said Auguste Clavel at the
Office of the Commissioners of Patents, with his Petition, on the 19th
. October 1864..
I, AUGUSTE CLAVEL, Merchant, of 51, Rue de Malte, Paris, in the
Empire of France, do hereby declare the nature of the said Invention for
"AN IMPROVEMENT IN THE MEANS OF HOLDING OR SUPPORTING GLASSES, SHADES, AND
REFLECTORS USED WITH LAMPS AND BURNERS," to be as follows:-
My Invention relates to the socket-holder or support used with lamps and
burners for receiving the glass or chimney; glasses or chimneys vary in
diameter, and frequently will not fit the socket, whence considerable incon-
venience arises.
My Invention also relates to the support or frame for holding reflectors or
shades at the upper part of glasses or chimneys, which supports as hitherto
constructed will not fit all chimneys nor all parts of one chimney.
Now the object of my Invention is to adapt one socket-holder, support, or:

page_text: frame for different sizes or diameters of glass or chimney. For this purpose
I construct the socket-holder or support of glasses or chimneys, or the ring or
lower part of the frame or support of shades and reflectors extensible and
contractible, or adjustable as to size, that is to say, I construct the same of
thin brass or other substance formed into a nearly annular shape, that is to
say, in the shape of an incomplete ring or circle with one or more openings
or breaks in its circumference, and the edges or sides of such opening or
break (or one such) are brought closer or separated by an adjusting screw
or other similar contrivance, so that the diameter or area of the holder,
_socket, support, or ring may be varied to fit glasses or chimneys of different
diameters or sizes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Auguste Clavel in the Great Seal Patent Office on the 19th
April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AUGUSTE
CLAVEL, Merchant, of 51, Rue de Malte, Paris, in the Empire of France,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Auguste Clavel, Her special licence that. I, the said Auguste Clavel,
my executors, administrators, and assigns, or such others as I, the said
Auguste Clavel, 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, THE MEANS OF HOLDING OR SUPPORTING GLASSES, SHADES, AND
REPLECTORS USED WITH LAMPS AND BURNERS," upon the condition (amongst
others) that I, the said Auguste Clavel, 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
monthis next and immediately after the date of the said Letters Patent.
"

page_text: NOW KNOW YE, that I, the said Auguste Clavel, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the accompanying Drawings, that is
to say:-
My Invention relates, first, to the socket-holder or support used with
lamps and burners för receiving the glass or chimney; glasses or chimneys
vary in diameter, and frequently will not fit the socket, whence considerable
inconvenience arises..
My Invention also relates to the support or frame for holding reflectors or
shades at the upper part of glasses or chimneys, which supports' as hitherto
constructed will not fit all chimneys, nor all parts of one chimney.
Now the object of my Invention is to adapt one socket-holder, support,
or frame for different sizes or diameters of glass or chimney. For this pur-
pose I construct the socket-holder or support of glasses or chimneys and the
ring or lower part of the frame or support of shades and reflectors extensiblė
and contractible or adjustible as to size, so that the diameter or area of the
holder, socket, support, or ring may be varied to fit glasses or chimneys of
different diameters or sizes.
I now proceed, with reference to the Drawings, to describe in what
manner the Invention may be carried into effect. .
The Drawings shew .my various arrangements in which I effect the
required expansion and contraction by a conical ring or by an incomplete
ring with a screw, or by constructing the support or socket itself in tho
form of an incomplete ring or interrupted cylinder expanded and contracted
by a screw..
In all the Figures A is the socket, support, gallery, or holder for the glass
or chimney, and B the wick-holder or burner..
Figure 1 is a front view, and Figure 2 a plan of one arrangement in which'
the support A, which receives the glass, is made of thin brass, and formed with
six vertical slots a, a, a, which render it springy or sufficiently elastic to
receive glasses of various sizes. To the outer side of the springy support A
is rivetted a brass ring or incomplete. ring D of the shape of a circle with a
break or opening in it at c. Through the ends d, d', of the ring which form.
the lips or sides of this opening a screw v passes, whereby the ends d, d¹, are
brought nearer to or farther from each other; and the ring D is thereby
expanded or contracted, hence regulating the area or diameter of the
port A, and adapting it for glasses of different sizes.
sup-

page_text: Figure 3 is a front view of a modification in which the support A is slotted,
as in Figures 1 and 2, but instead of being cylindrical it is conical, and over-
it is fitted a ring D, which is also conical or tapering; or broader at bottom
than at top, and is free to slide up and down on the support A. The ring
when slidden downward contracts the area of the holder A, and when slidden
upward it expands it, or allows it to resume its original area.
Figure 4 is a vertical section, Figure 5 an elevation, and Figure 6 a plan
of another arrangement. Here the support or holder A is of the form of an
incomplete cylinder or ring, that is to say, it is cut away vertically or formed
with a break or opening c, which interrupts the continuity of its cylindrical
-shape:; the ends, lips, or sides d, d', of this break c are bent up at right
angles, as shewn, and a screw vis passed through-them-whereby they may be
brought nearer to or farther from each other, and the area or size of the
support A is thereby varied or regulated so as to adapt it to receive glasses of
various sizes. The holder A is cut away horizontally at a, a, so that for
about two-thirds of its circumference it does not touch the burner or wick-
holder B, and hence is not prevented from being acted on by the screw v; this
socket holds the glass more securely than does the conical one.
Figure 7 is an elevation, and Figure 8 a plan of a modification in which
the holder A is of similar shape to that shewn in Figures 4, 5, and 6,
except that the ends or lips d, d', are jointed.. to the body of the holder by
hinges i, i. In this modification the socket, support, or holder A is not
attached to the burner B at bottom, but is only connected therewith by
three hooks or pins a, a, which slide in grooved guide ways c, e, formed in the
top of the burner.
Figure 9 is an elevation, and Figure 10.a plan shewing my improved
support or frame for shades or reflectors which I render adjustable as to size
at the part D which fits on the glass or chimney. The ring or lower part D
of this support or frame is an incomplete or interrupted ring or a ring divided
by a break or opening c, the sides d, d', of which, which form the ends of the
ring, are brought nearer to or farther from each other by a screw v, which
passes through them, whereby the ring D is secured on the glass or chimney G,
and expanded or contracted as required, according to the size of glass or
chimney; e, e, e, are wire arms soldered to the ring D for carrying the shade
or reflector.
Having now-described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim,
First, the socket, support, or holder in which the expansion and contraction,

page_text: or variation of size or area are effected by slots and by an incomplete ring
and screw, or by a conical ring, as exemplified in Figures 1, 2, 3, of the
Drawings, and herein-before described.
Second, the socket, support, or holder rendered expansible (or extensible)
and contractible by a screw, as herein-before described and represented in
Figures 4, 5, and 6 of the Drawings.
Third, the socket, support, or holder connected with the lamp or burner by
hooks or pins, and rendered expansible (or extensible) and contractible by a
screw, as herein-before described and exemplified in Figures 7 and 8 of the
Drawings.
Fourth, the frame or support for shades or reflectors rendered extensible
and contractible at the part which fits on the glass or chimney, as herein-
before described and represented in Figures 9 and 10 of the accompanying
Drawings.
In witness whereof, I, the said Auguste Clavel, have hereunto set my.
hand and seal, this Thirteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-five.
Witness,
⚫ BRESSON.
