Year: 1859

page_text: LETTERS PATENT to Charles Bacon, of Edgware Road, in the County of
Middlesex, Esquire, for the Invention of "IMPROVEMENTS IN GLOBES AND
SHADES FOR GAS LIGHTS AND OIL OR OTHER LAMPS."
Sealed the 1st May 1860, and dated the 3rd November 1859.
PROVISIONAL SPECIFICATION left by the said Charles Bacon at the
Office of the Commissioners of Patents, with his Petition, on the
3rd November 1859.
I, CHARLES BACON, of Edgware Road, in the County of Middlesex, Esquire,'
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
GLOBES AND SHADES FOR GAS LIGHTS AND OIL OR OTHER LAMPS," to be as
follows:-
This Invention consists in forming the globes and shades for gas lights and
lamps with an interior globe or convex lining, the space between the outer
and inner globe or lining forming a receptacle for clear water or other bright
liquid, plain or colored, as may be desired; the space between the outer and
inner globe or lining may be left open at the top or be fitted with a moveable
glass cap or cover. Or, instead of the inner globe or lining a convex or
suitably shaped chimney may be attached or secured to the lower part of the
outer globe, leaving the space between the interior of the globe and the
chimney for the reception of water or other liquid as above stated; in this case
also the glass cap or cover above referred to may be used.
The effect of this Invention is to increase the illuminating power and
produce a clear shadowless light, either bright or tinted, of greater intensity
than by the ordinary globes and shades now in use.

page_text: This Invention will be equally suitable for gas, oil, spirit, or candle lamps,
whether for domestic, shop, or street use, or for railway or other signal
lights.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Bacon in the Great Seal Patent Office on the 3rd
May 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
BACON, of Edgware Road, in the County of Middlesex, Esquire, 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-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles Bacon, Her special licence that I, the said Charles Bacon, my
executors, administrators, and assigns, or such others as I, the said Charles
Bacon, 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 GLOBES AND
SHADES FOR GAS LIGHTS AND OIL OR OTHER LAMPS," upon the condition (amongst
others) that I, the said Charles Bacon, 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 Charles Bacon, 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, that is to say:-
This Invention consists in forming the globes and shades of gas lights and
lamps with an interior globe or globes, the spaces between the outer and inner
globes forming receptacles for water or other clear liquid, plain or coloured, as
may be desired. The spaces between the outer and inner globes may (one
or all be filled with liquid according to the power of light required to be

page_text: obtained. And the inner globe may be formed either of solid glass bored or
cut through the centre, or in compartments, in a suitable manner, or hollow,
the interior being filled with water or other clear liquid; any number of globes
may also be added with the lights systematically arranged according to the
illuminating power required, and which can be still further increased by a
peculiar adjustment of reflectors.
In some cases the globes may be of solid glass bored or cut with a six or
eight sided hole, or the hole may be fluted or grooved in the interior, and
around the centre hole may be formed other vertical holes which do not pass
entirely through the glass, thus forming receivers for clear liquid, and reflecting
the light from the centre or chimney. Where much light is required the
burners may be placed around the inner globe, which may be either solid or
hollow and filled with water, the centre opening being used for the oil or gas
tube to pass through which supplies the burners; or the burners may be
arranged in a triangular, quadrilateral, or other form around the inner globe
or globes, and an outer double globe filled with liquid may also be used; thus
the light is reflected from one globe to the other, increasing the power of
the light, which may still further be increased as required by the adjustment
of reflectors.
This Invention is alike applicable to railway and other signal lights.
Having now fully described the nature and object of my said Invention of
"Improvements in Globes and Shades for Gas Lights and Oil or other
Lamps," together with the manner in which the same is to be performed, I
would remark, in conclusion, that I do not confine or restrict myself to the
precise details herein described, as many slight modifications may be made in
the same without at all departing from the principle of my Invention; but
what I claim as my Invention is the making of globes and shades for gas, oil,
or other lights, in the manner herein described and for the purposes set forth.
In witness whereof, I, the said Charles Bacon, have hereunto set my
hand and seal, this Twenty-eighth day of April, in the year of our
Lord One thousand eight hundred and sixty.
Witness,
ALEX. PRINCE, Patent Agent,
