Year: 1865

page_text: LETTERS PATENT to George Henry Brookes, of Sheffield, in the County
of York, for the Invention of "IMPROVEMENTS IN SLIDING GAS PENDENTS
OR CHANDELIERS."
Sealed the 10th November 1865, and dated the 19th May 1865.
PROVISIONAL SPECIFICATION left by the said George Henry Brookes
at the Office of the Commissioners of Patents, with his Petition, on the
19th May 1865.
I, GEORGE HENRY BROOKES, of Sheffield, in the County of York, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN SLIDING GAS
PENDENTS OR CHANDELIERS," to be as follows:-
My Invention then is for to break or reduce the sudden shock or noise now
felt and heard in some sliding gas pendents or chandeliers when in motion, or
on their reaching their extreme points of motion. And to accomplish this I
intend to introduce springs or some elastic or yielding substance, or both
combined, and introduced at either end of the rods or tubes, or inside or
outside the same, or around the wheels or pulleys, or tubes, or other parts of
the said pendents or chandeliers, and to so adjust the springs or other
mentioned substances aforesaid, that on the opposing parts or points meeting

page_text: or coming into contact with each other the shock and noise will be con-
siderably broken and reduced; and also by so adjusting the above-mentioned
substances or things I purpose that the friction and noise shall be so lessened
as to make the said pendents or chandeliers work better and less objectionably
than now.
I adjust the springs for the purpose above said in the following manner :-
I place a spring or springs at the bottom of the outer or sliding tube, or at the
top of the same, to act as a buffer or repelling agent when the opposing parts
are meeting. The said springs, wherever they are placed, are to be for the
reducing of the shock and noise caused by the opposing parts meeting.
I claim to use also in the place of springs some repelling agent, such as
vulcanized india-rubber, to act for the same purpose; and I also place over or
around the wheels or pulleys to check or deaden the sound of the chains or
other material passing over them vulcanized india-rubber or some such elastic
substance; also around the inner tube I place a piece of some elastic substance
to reduce the friction and noise.
I claim also, if preferred, to make the wheels or pulleys of a noiseless
character when in action in lieu of brass, as now used; and I prefer making the
same of vulcanized india-rubber or some similar substance.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Henry Brookes in the Great Seal Patent Office on
the 17th November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HENRY BROOKES, of Sheffield, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of May, in the year of our Lord
One thousand eight hundred and sixty-five, in the eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
George Henry Brookes, Her special licence that I, the said George Henry
Brookes, my executors, administrators, and assigns, or such others as I, the
said George Henry Brookes, 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

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN SLIDING GAS PENDENTS OR CHANDELIERS," upon the condition
(amongst others) that I, the said George Henry Brookes, 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 per-
formed, 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 George Henry Brookes 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 :-
My Invention then is for to break or reduce the sudden shock or noise now
felt and heard in some sliding gas pendents or chandeliers when in motion, or
on their reaching their extreme points of motion, and to accomplish this I
intend to introduce springs or some elastic or yielding substance, or both com-
bined and introduced at either ends of the rods or tubes, or inside or outside
the same, or around the wheels or pullies, or tubes, or other parts of the said
pendents or chandeliers, and to so adjust the springs or other mentioned
substances aforesaid, that on the opposing parts or points meeting or coming
into contact with each other the shock and noise will be considerably broken
and reduced; and also by so adjusting the above-mentioned substances or
things, I purpose that the friction and noise shall be so lessened as to make
the said pendents or chandeliers work better and less objectionable than
now.
I adjust the springs for the purpose above said in the following manner :-
I place a spring or springs at the bottom of the outer or sliding tube, or at
the top of the same, to act as a buffer or repelling agent when the opposing
parts are meeting. The said springs, wherever they are placed, are to be
for the reducing of the shock and noise caused by the opposing parts
meeting.
I claim to use also in the place of springs some repelling agent, such as
vulcanized india-rubber, to act for the same purpose, and I also place over or
around the wheels or pulleys to check or deaden the sound of the chains or
other material passing over them vulcanized india-rubber or some such
elastic substance. Also around the inner tube I place a piece of some elastic
substance to reduce the friction and noise.
I claim also, if preferred, to make the wheels or pulleys of a noiseless

page_text: character when in motion in lieu of brass, as now used; and I prefer making
the same of vulcanized india-rubber or some similar substance.
Having described the nature of my Invention, I will proceed to describe,
with reference to the accompanying Drawing, the manner in which the same
is to be performed.
Fig. 1 represents the upper part of a gas pendent or chandelier where the
wheels or pulleys are, and from which the balance weights are suspended.
Around these wheels, which are the ordinary ones in use, and in the groove
on the edge where the chain runs, I place a band of vulcanized india-rubber
or some such soft substance to reduce the friction and deaden the noise of the
said chains and wheels when in motion.
I would also, if preferred, make the said wheels entirely of vulcanized india-
rubber or some such material in lieu of brass, as now used.
The spiral spring, as seen in Fig. 1, and coloured blue and marked A, I
place there for the bottom of the water cup B to push against in its upward
movement to reduce the shock and noise caused by any two parts of the
pendent meeting; this said spring is merely placed around the fixed tube, and
has the ordinary collar to press against, marked C. In combination with the
above said spring, or without its help, I accomplish the same by placing the
spring at the bottom of the outer or water slide tube E; in Fig. 2 the same
spring is merely placed over the inner or gas tube 3, and can be removed at
pleasure. The end of the fixed tube 2, which in ordinary pendents comes
down to the solid end G of the outer tube E, when the same is pushed up, it
is now received by the spring and breaks its force, thus reducing the shock
caused as in ordinary pendents or chandeliers by the two inflexible substances
coming into contact. This same effect in a lesser form I can accomplish also
by using some yielding substance, such as vulcanized india-rubber, in the place
of springs, but I give the preference to springs.
The form of the springs to be spiral, conical, or otherwise, to suit the nature
of the chandelier, or the same can be placed in any other part of the pendent
or chandelier than shown in the Drawing to suit the convenience of design
and manufacture; but in all cases I purpose to use the same means to
accomplish the same end. I also place around the inner or gas tube 3 a
piece of soft material, such as vulcanized india-rubber tubing, covering it its
intire length to reduce the friction of the two tubes 2 and 3, or what I call
the fixed tube and the inner or gas tube 3.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I wish it to be understood that I do not
limit myself to the precise details herein described and represented in the

page_text: Drawing, as the same may be varied without departing from the nature of my
Invention; but I claim as my Invention the improvements in the construction
of sliding gas pendents or chandeliers, by which improvements I am enabled
to reduce the noise and shock now felt and heard in ordinary pendents or
chandeliers, as herein fully described and illustrated.
In witness whereof, I, the said George Henry Brookes, have hereunto
set my hand and seal, this Sixteenth day of November One thousand
eight hundred and sixty-five.
GEORGE HENRY BROOKES. (L.S.)
