IMPROVEMENTS IN LAMPS OR LIGHTING APPARATUS
Year: 1874

page_text: LETTERS PATENT to Joseph Norman Aronson, of the Langham Hotel,
Portland Place, in the County of Middlesex, Gentleman, for the
Invention of IMPROVEMENTS IN LAMPS OR LIGHTING APPARATUS,
PROVISIONAL SPECIFICATION left by the said Joseph Norman Aronson
at the Office of the Commissioners of Patents, with his Petition,
on the 21st August 1874.
I, JOSEPH NORMAN ARONSON, of the Langham Hotel, Portland Place,
in the County of Middlesex, Gentleman, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN LAMPS OR LIGHTING APPARATUS,"
to be as follows:-
In lamps and lighting apparatus as heretofore usually constructed for
use with chimneys, globes, and shades much inconvenience results from
the difficulty of gaining access to the burner as required for lighting

page_text: either gas or other lamps or lighting apparatus, or for trimming the
wick in lamps or apparatus designed for burning oil or spirit by means
of a wick, as well as in other cases where it is required to have access
to the burner, inasmuch as it is generally necessary for such purposes to
remove the chimney, globe, and shade, or such of these parts as may be
in use.
Besides the great trouble, inconvenience, loss of time, and annoyance
resulting from having to remove the chimney, globe, and shade, there is
the further serious drawback of constant liability to breakage of the
fragile parts so required to be removed, which breakages entail frequent
renewal of the parts and consequent expense.
Now my
Invention is
designed to obviate these inconveniences, and relates to the application
to and combination with the lamp or lighting apparatus of a gallery,
carrier, or support arranged to be moved up and down, and to carry with
it the chimney, globe, and shade, or such of these parts as may be in use
at the time being, so as to enable them or it to be readily moved into
and retained in a position permitting of access to the burner by simply
raising the moveable gallery, carrier, or support, which may be done by
the direct application of the hand of the operator.
The moveable gallery, carrier, or support is by preference made of
annular form in plan, with a guard or guards or holder for holding and
retaining in position the chimney, globe, and shade, or such of these parts
as may be required to be used; and this gallery, carrier, or support is
connected to a vertically sliding part or parts combined with, guided,
and supported by the pillar or body of the lamp or lighting apparatus,
so as to be capable of being slid or moved up and down by hand, carrying
with it the gallery, carrier, or support, and the chimney, globe, and
shade, as above explained.
I prefer to make the vertically sliding part in the form of a ring
clasping the pillar or body of the lamp or lighting apparatus, and con-
nected to the gallery, carrier, or support by a rod or rods, but it will be
evident the arrangement may be modified to suit circumstances without
departing from the distinctive character of my Invention.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Joseph Norman Aronson in the Great Seal Patent
Office on the 20th February 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
NORMAN ARONSON, of the Langham Hotel, Portland Place, in the County
of Middlesex, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of August, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Joseph Norman Aronson, Her
special license, that I, the said Joseph Norman Aronson, my executors,
administrators, and assigns, or such others as I, the said Joseph
Norman Aronson, 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 law-
fully 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 OR LIGHTING APPARATUS,"
upon the condition. (amongst others) that I, the said Joseph Norman
Aronson, 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 Joseph Norman Aronson, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, and the Sheet of Drawings therein
referred to (that is to say) :-
In lamps and lighting apparatus as heretofore usually constructed for
use with chimneys, globes, and shades much inconvenience results from
the difficulty of gaining access to the burner as required, whether for
lighting in the case of gas and other lamps or lighting apparatus, or for

page_text: trimming the wick in lamps or apparatus designed for burning oil or
spirit by means of a wick, as well as in other cases where it is required
to have access to the burner, inasmuch as it is generally necessary for
such purposes to remove the chimney, globe, and shade, or such of these
parts as may be in use.
Besides the great trouble, inconvenience, loss of time, and annoyance
resulting from having to remove the chimney, globe, and shade, there is
the further serious drawback of constant liability to breakage of the
fragile parts so required to be removed, which breakages entail frequent
renewal of the parts and consequent expense. Now my Invention is
designed to obviate these inconveniences, and relates to the application
to and combination with the lamp or lighting apparatus of a gallery,
carrier, or support arranged to be moved up and down and to carry with
it the chimney, globe, and shade, or such of these parts as may be in use
at the time being, so as to enable them or it to be readily moved into
and retained in a position permitting of access to the burner by simply
raising the moveable gallery, carrier, or support, which may be done by
the direct application of the hand of the operator.
The moveable gallery, carrier, or support is by preference made of
annular form in plan, with a guard or guards or holder for holding and
retaining in position the chimney, globe, and shade, or such of these
parts as may be required to be used, and this gallery, carrier, or support
is connected to a vertically sliding part or parts combined with, guided,
and supported by the pillar or body of the lamp or lighting apparatus,
so as to be capable of being slid or moved up and down by hand, carrying
with it the gallery, carrier, or support, and the chimney, globe, and
shade, as above explained.
The vertically sliding part may be made in the form of a ring clasping
the pillar or body of the lamp or lighting apparatus, and connected to
the gallery, carrier, or support by a rod or rods, but it will be evident
the arrangement may be modified to suit circumstances without departing
from the distinctive character of my Invention.
Such being the nature of my said Invention I now proceed to describe
the manner of carrying the same into practical effect, as illustrated in the
accompanying Drawings, in which the same letters of reference are used
to denote like parts in all the views.

page_text: Fig. 1 is a vertical section of part of a lamp embodying my Invention.
Around the tube a is a ring b capable of being moved up and down on
the said tube, but fitting closely thereto, so as to move only with a
moderate amount of friction. To this ring are secured or fastened the
lower ends of the rods c, whose upper ends are fixed to the gallery,
carrier, or part d, which carries the chimney, globe, or shade. The
burner e is arranged to screw on to the upper end of the tube a, as
shewn. By this arrangement it will be obvious that on raising the
gallery or carrier into the position indicated by dotted lines the chimney,
globe, or shade will be supported above the burner sufficiently to enable
a light to be applied for igniting the wick, or to enable the light to be
extinguished.
Fig. 2 is a side elevation of another arrangement of burner combined
with apparatus according to my Invention, the gallery, carrier, or support
being shewn in its lowered or normal position; and Fig. 3 is a similar
view shewing the gallery, carrier, or support raised. In this arrange-
ment the burner is arranged to screw into the lamp tube, which is not
shewn in the Drawing. The lower ends of the rods c fit closely into a
couple of sockets or tubes f with sufficient friction to retain the gallery,
carrier, or support with the chimney, globe, and shade when raised in
the position shewn in Fig. 3. g is a tube for feeding oil to the lamp.
My plan of raising and lowering the gallery, carrier, or its equivalent
may obviously be applied to various kinds of lamps and lighting
apparatus.
Having described the nature of my said Invention, and having
explained the manner of carrying the same into practical effect, I hereby
declare what I consider to be novel and original and therefore claim as
the Invention secured to me by the herein-before in part recited Letters
Patent to be,
First. The arranging the gallery, carrier, or equivalent part of a lamp
or lighting apparatus to move up and down so as to enable the chimney,
globe, and shade or any of them to be raised sufficiently to permit of
access to the burner for lighting and other purposes, substantially as
above described.
Secondly. The combinations of parts constituting my improved appa-
ratus constructed, arranged, and operating as shewn in and described

page_text: with reference respectively to Fig. 1, and to Figs. 2 and 3 of the Drawings
for the purpose specified.
In witness whereof, I, the said Joseph Norman Aronson, have
hereunto set my hand and seal, this Twentieth day of February,
in the year of our Lord One thousand eight hundred and seventy-
five
