IMPROVE- MENTS IN LAMPS
Year: 1867

page_text: LETTERS PATENT to William Jones, of Liverpool Street, King's Cross, in
the County of Middlesex, Gas Engineer, for the Invention of "IMPROVE-
MENTS IN LAMPS."
Sealed the 9th August 1867, and dated the 13th February 1867.
PROVISIONAL SPECIFICATION left by the said William Jones at the
Office of the Commissioners of Patents, with his Petition, on the
13th February 1867.
J, WILLIAM JONES, of Liverpool Street, King's Cross, in the County of
Middlesex, Gas Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN LAMPS," to be as follows:-
My Invention relates to lamps intended to be used for throwing light on.
to shop windows from outside, and for other purposes, and consists of a globe.
of glass, the half of which next the window is composed of transparent glass,
and the binder or outer half is composed of enamelled glass or other semi-
transparent substance adapted for reflecting the light of an internal gas
burner on to the window. The hinder or outer half of the globe may be also
composed of silvered glass, or enamelled iron, or other suitable material with
a lining or coating adapted for reflecting light as required. In some cases it
may be advisable to vary the form of the globe, which is composed of two

page_text: convex glasses, as above stated, and to make it somewhat flattened instead of
being spherical. The globe is suspended by means of a metallic band, by
which it is encircled from a gas supply pipe in the form of two supporting
arms fixed at the two opposite sides of the band, one of which-arms conveys
the requisite supply of gas to a ring inside the band, and thence to the
Lurner, the air being admitted as required through suitable apertures in
the band. The glass chimney of the burner extends through an aperture in
the top of the globe into a metal shaft with a cowl at the top, such metal
shaft being supported quite independently of the globe and prevented by
stops from resting on the top of the same; this metal shaft is capable of being
raised and lowered as required by working in vertical guides on the suspending
arms.
The above described mode of suspending may be adapted and applied to
other descriptions of lamps.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Jones in the Great Seal Patent Office on the
9th August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JONES, of Liverpool Street, King's Cross, in the County of Middlesex, Gas
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of February, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Jones, Her special licence that I, the said William
Jones, my executors, administrators, and assigns, or such others as I, the said
William Jones, 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 LAMPS,"
upon. the condition (amongst others) that I, the said William Jones, 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

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Jones, do hereby declaro
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, reference being had to the Drawings hereunto annexed, and to the
letters and figures marked thereon (that is to say) :-
My Invention of "Improvements in Lamps" relates to such as are
intended to be used for throwing light on to shop windows from outside, and for
other purposes, and consists of a globe of glass, the half of which next the window
is composed of transparent glass, and the hinder or outer half is composed
of enamelled glass or other semi-transparent substance adapted for reflecting
the light of an internal gas burner on to the window. The binder or outer
half of the globe may be also composed of silvered glass, or enamelled iron,
or other suitable material with a lining or coating adapted for reflecting light
as required. In some cases it may be advisable to vary the form of the
globe, which is composed of two convex glasses, as above stated, and to make
it somewhat flattened instead of being spherical. The globe is suspended by
means of a metallic band (by which it is encircled) from a gas supply pipe,
in the form of two supporting arms fixed at the two opposite sides of the
band, one of which arms conveys the requisite supply of gas to a ring inside
the band, and thence to the burner the air being admitted as required through
suitable apertures in the band. The glass chimney of the burner extends
through an aperture in the top of the globe into a metal shaft with a cowl at
the top, such metal shaft being supported quite independently of the globe,
and prevented by stops from resting on the top of the same; this metal shaft
is capable of being raised and lowered as required by working in vertical
guides on the suspending arms.
The above described mode of suspending may be adapted and applied to
other descriptions of lamps.
Having thus stated the nature of the said Invention I will proceed to
describe more particularly in what manner the same is to be performed by
reference to the accompanying Drawings, in which are represented a lamp
constructed in the manner above referred to.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an elevation of a lamp as seen on looking towards the window out-
side of which it is suspended, and Fig. 2 is a transverse section of the same. In
both these Figures the same letters of reference indicate corresponding parts.

page_text: A is the half of the globe next the window, which half is composed of
transparent glass; B is the other half of the same composed of enamelled
glass or other semi-transparent substance adapted for reflecting the light of
the burner on to the window, or it may be composed of silvered glass or
enamelled iron with a lining or coating adapted for reflecting light as required;
C is a metallic band by which the globe is encircled and suspended from a gas
supply pipe D; this pipe is shewn in the form of two supporting arms, one
of which serves to convey the requisite supply of gas to a ring E inside the
band C, and thence to the burner F, the air being admitted as required for
supporting combustion through apertures in the band C, which apertures
may be ornamental in form; G is a glass chimney which extends through an
aperture H in the top of the globe into the metal shaft I which is surmounted
by a cowl of metal K. The shaft I is suspended from a fixed ring L, and is
thus supported independently of the globe, it is also prevented by stops M, M,
from resting upon the globe, and is capable of being raised or lowered as
required by guides fixed thereto sliding on the vertical parts of the suspending
arms.
Having thus described the nature of the said Invention, and in what manner
the same is to be performed, I would remark that although my Invention as
described relates more particularly to outside lamps, yet it may also be
applied to lamps for halls and other inside situations, but I hereby declare
that what I claim as of my Invention is, the manufacture of lamps in the
form of a globe or other similar form, one half of which globe is composed of
transparent glass and the other of a semi-transparent material or of an opaque
material lined with a reflecting material, such globe being supported by
means of an encircling ring of metal and suspending arms, and provided with
a metal shaft adapted to receive the upper end of the glass chimney supported
independently of the globe, as herein-before described.
In witness whereof, I, the said William Jones, have hereunto set my
hand and seal, the Seventh day of August, in the year of our Lord
One thousand eight hundred and sixty-seven.
Witness,
WILLIAM SPENCE,
