IMPROVE- AND STUND PENDENT LAMDQ
Year: 1862

page_text: LETTERS PATENT to Henry William Sambidge, of Birmingham, in the
County of Warwick, Manufacturer, for the Invention of "IMPROVE-
AND STUND PENDENT LAMDQ"
PROVISIONAL SPECIFICATION left by the said Henry William Sambidge
at the Office of the Commissioners of Patents, with his Petition, on
the 10th May 1862.
I, HENRY WILLIAM SAMBIDGE, of Birmingham, in the County of Warwick,.
Manufacturer, do hereby declare the nature of the said Invention for.
"IMPROVEMENTS IN SLIDING CHANDELIERS, GASALIERS, AND OTHER PENDENT LAMPS,".
to be as follows, that is to say :-
My Invention consists of improvements in the slides of such pendent lamps.
as are required to be raised and lowered at will, and for gas pendents. I also
dispense with the use of water by the following means:-The inner tube which,
in gasaliers conveys the gas to the body of the lamp I remove altogether,
substituting in place thereof a tube of vulcanized india-rubber containing a
spiral spring if requisite. The upper end of this rubber tube is secured to a.
nozzle inside the cup of the usual ball joint or to the top connection or neck
which may be used in place of the ball joint; the lower end of the tube is.
connected under the pommel of the outside down rod by a similar nozzle

page_text: or flanged collar. In case of the breakage of the balance chain the rubber
tube prevents the lamp from running down, and if it be applied to a gasalier
there is no escape of gas.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry William Sambidge in the Great Seal Patent Office
on the 8th November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
WILLIAM SAMBIDGE, of Birmingham, in the County of Warwick, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of May, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Henry William Sambidge, Her special license that I, the said Henry William
Sambidge, my executors, administrators, and assigns, or such others as I, the said
Henry William Sambidge, 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 SLIDING CHADELIERS, GASALIERS, AND OTHER PENDENT LAMPS,"
upon the condition (amongst others) that I, the said Henry William
Sambidge, by an instrument in writing under my hand and seal, 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 Henry William Sambidge, 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, reference being had to the Drawings hereunto annexed
and to the letters and figures marked thereon (that is to say):-
My Invention consists of improvements in the slides of such pendent lamps
as are required to be raised and lowered at will, and for gas pendents. I also
dispense with the use of water by the following means:-The inner tube which

page_text: in gasaliers conveys the gas to the body of the lamp I remove altogether,
substituting in place thereof a tube of vulcanized india-rubber containing a
spiral spring if requisite. The upper end of this rubber tube is secured to a nozzle
inside the cap of the usual ball joint or to the top connection or neck, which
may be used in place of the ball joint; the lower end of the tube is connected
under the pommel of the outside down rod by a similar nozzle or flanged
collar. In case of the breakage of the balance chains the rubber tube prevents
the lamp from running down, and if it be applied to a gasalier there is no
escape of gas.
I will now proceed to give a more detailed description of my Invention by
the aid of the annexed Drawing, which represents in vertical section that
portion of a gasalier in which the slide apparatus is contained.
(a) is the usual top connection or ceiling plate; (b), the common ball joint
through which the tube (c) passes. This tube (c) has an inner tube (d),
which tube is made of vulcanized india-rubber, and may contain, if requisite,
a spiral spring to assist its action. The india-rubber tubo (d) is secured at
the upper end within the tube (c) in the following manner:-A thimble or
nozzle (E) is forced into the upper end of the tube (d), distending it until it
will not pass down the tube (c), but is gripped and firmly held between the
thimble or nozzle (E) and the edge of the tube (c). The lower end of the
tube (d) is secured in a similar manner by a thimble or nozzle (f) to a gland
or collar (9) attached to the outside tube (h), and is concealed by the ponimel
or body (k) of the gasalier. Thus the upper end of the india-rubber tube is
secured to the metal tube (c), whilst the lower end is connected to the tube
(h), and the entire gasalier subject to the equilibrium caused the balance
weights hangs by the india-rubber tube. (7) is the usual appliance to which
the carrier for the pulleys of the balance weights are attached in the ordinary
manner, and underneath the part (1) is a gland or stuffing box (m) as a
further security against the escape of gas and to assist the balance.
From the preceding description of my Invention as applied to a gasalier it
will be easily seen that deprived of those parts essential only to a gas pendent
the vulcanized tube can in this manner be readily employed in connection
with chandeliers and pendents of various descriptions other than those used for
gas, so that further description of its employment in such cases is not
necessary.
Having thus described the nature of my said Invention, and in what
manner the same is to be performed, I do not confine myself to the precise
details herein specified as they may be considerably varied, but that which I

page_text: claim is the employment of a vulcanized india-rubber or spring tube with the
slides of pendent lamps, by which I can dispense with the use of water slides as
herein more fully set forth and specified.
In witness whereof, I, the said Henry William Sambidge, have hereunto
set my hand and seal, this Seventh day of November in the year 5
of our Lord One thousand eight hundred and sixty-two.
HENRY WILLIAM SAMBIDGE. (L.S.)
