PROVISIONAL SPECIFICATION.
Improvements in Gasaliers, Electroliers, and Pendants, which are
also applicable for Oil or Spirit Lamps.
I, CHARLES SMITH, of No. 27 Durham Road, Sparkhill in the County of
Worcester, Commercial Traveller, do hereby declare the nature of this invention
to be as follows:-
:-
This invention relates to the improvements hereinafter described in gasaliers,
electroliers, and pendants, and consists principally in the construction and
arrangement of the slide whereby the old form of water slide projecting balance
weights and chains arrangements are dispensed with, and the danger of the weights
falling and the gas escaping caused by the breaking of chains is entirely obviated.
My invention is also applicable to oil and spirit lamps in which a telescopical slide
or pendant is used.
By my invention I construct a telescopical tubular slide in such a manner as to
dispense with the water slide and to enable it to be lengthened or shortened, that is
to say, the gas jets may be raised or lowered by the aid of one weight instead of
two, or I may use a rapid pitch or "Archimedean screw or its equivalent formed
on the telescopical tubular slides for the said purpose.
"
In carrying my invention into practice as applied to a two or more light gasalier,
I provide an external tube depending from an ordinary ceiling joint, along the
length of the said tube and at equal distance from each other I form two grooves,
I fit telescopically into the said tube an internal tube carrying the gas brackets or
arms with the burners and fittings attached, the connection between the two tubes
being formed either with a stuffing box or other suitable device to prevent the
escape of gas. To the ceiling joint or to the top external tube I attach two small
pulleys central with the grooves in the external tube aforesaid. I provide an
ornamental balance weight which encircles the external tube and capable of sliding
thereon, to a convenient part of the said weight. I attach a chain which passes
along one of the grooves and over one of the pulleys aforesaid and hence over the
second pulley and down the second groove, the end of the chain being attached to
a convenient part of the lower end of the internal tube. It will be thus apparent
that the gas lights may be easily raised or lowered and retained in any desired
position by a slight pull downwards or a pressure upward, the balance weight
aforesaid compensates for the weight of the fittings on the internal tube.

I may in some cases dispense with the balance, weight and chain arrangement
aforesaid and reduce a portion of the diameter of the external tube which I form
into a screw socket furnished with a rapid pitch or an Archemedean
also screw the entire length of the internal tube, externally with a corresponding
thread. The lower end passing through a socket formed in gas bracket is provided
with a terminal knob or ring for the purpose of revolving the said tube either in
one direction or the other which will raise or lower the gas lights, or instead of
screwing the tubes 1 may form circular grooves or indentations along the entire
length of the internal tube and attach to the end of the external tube a clip,
formed in such a manner as to engage in the indentations aforesaid and hold the

page_text: internal tube in any desired position, by expanding the clip the said tube may be
raised or lowered as desired, thus adjusting the height of the gas jets.

Improvements in Gasaliers, Electroliers, and Pendants, which are
also applicable for Oil or Spirit Lamps.
I CHARLES SMITH of No. 27 Durham Road Sparkhill in the County of
Worcester Commercial Traveller do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to the improvements hereinafter described in gasaliers
electroliers and pendants and consists principally in the construction and
arrangement of the slide, whereby the old form of water slide projecting balance
weights and chains arrangements are dispensed with and the danger of the weights
falling and the gas escaping caused by the breaking of chains is entirely obviated.
My invention is also applicable to oil and spirit lamps in which a telescopical slide
or pendant is used.
By my invention 1 construct a telescopical tubular slide in such a manner as to
dispense with the water slide and to enable it to be lengthened or shortened that is
to say, the
gas jets may be raised or lowered by the aid of one weight instead of
two or more, or I may use a rapid pitch or
27
"Archimedean screw or its equivalent
formed on the telescopical tubular slides for the said purpose.
In carrying my invention into practice as applied to a two or more light gasalier,
I provide an external tube depending from an ordinary ceiling joint, along the length
of the said tube and at equal distances from each other, I form two grooves. I fit
telescopically into the said tubes an internal tube, carrying the gas brackets or
arms with the burners and fittings attached, the connection between the two tubes
being formed with a stuffing box or other suitable device to prevent the escape of
gas. To the ceiling joint or to the top of the external tube attach two small
pulleys. I provide an ornamental balance weight which encircles the external
tube and is capable of sliding thereon. To a convenient part of the said weight I
attach two chains one on either side which pass along the grooves, and over the
pulleys aforesaid.
The end of each chain is attached to a convenient part of the lower end of the
internal tube. It will be thus apparent that the gas lights may be easily raised or
lowered and retained in any desired position by a slight pull downwards, or a
pressure upwards, the balance weight aforesaid compensates for the weight of the
fittings on the internal tube.
1
I may in some cases dispense with the balance weight and chain arrangement
aforesaid, and reduce a portion of the diameter of the external tube which I form
into a screw socket furnished with a rapid pitch or an "Archimedean screw.
also screw the entire length of the internal tube, externally with a corresponding
thread. The lower end passing through a socket formed in the gas bracket is
provided with a terminal knob or ring for the purpose of revolving the said tube
either in one direction or the other which will raise or lower the gas lights or
instead of screwing the tubes I may form circular grooves or indentations along
the entire length of the internal tube and attach to the end of the external tube
a clip, formed in such a manner as to engage in the indentation aforesaid and hold

page_text: the external tube in any desired position. By expanding the clip the said tube
may be raised or lowered as desired thus adjusting the height of the gas jets.
I will now proceed to describe by reference to the accompanying drawings the
same letters of reference indicating similar parts throughout.
Fig. 1 illustrates a gasalier constructed in accordance with my invention
consisting of the internal sliding tube A which conveys the gas to the burners.
B represents a second tube, the top B2 being attached to the ceiling joint is furnished
with two small pulleys b, b. C is the external tube attached at the top to the
tube B and furnished at the bottom with a stuffing box D, or other suitable device to
prevent the escape of gas (this being of ordinary construction I do not consider it
necessary to describe it). E represents a groove in each side of the tube C nearly
central with the pulleys b, b. The balance weight F is suspended by the chains H³, H¹,
attached to the ears R, R, the said chains pass between the tubes C and B
also between the slots E, E, and over the pulleys b, b, and down the space between
the tubes B and A, the ends being secured at II. The positions of the chains in
the tubes are shown more clearly in Figures 7 and 8. It will be obvious that the
gas lights may be raised or lowered and retained in any desired position by means
of the chain and balance weight.
Fig. 2 shows another arrangement in which the sliding tube A is raised or
lowered by means of a rapid pitch or "Archimedean" screw which works into the
screw socket K, and is operated by the ring d, and is prevented from sliding out
thereof by the washer d, the escape of gas being prevented by a similar arrange-
ment to that described in Fig. 1.
Fig. 3. shows an arrangement in which a few screw threads M are placed at
intervals along the external tube A, for the purpose of raising or lowering the
gas jets.
Fig. 4 shows a gasalier in which the internal tube A is furnished with circular
grooves or indentations N along the entire length. P is a clip which encircles the
tube A and clips it, fitting the indentations, and thus holding the internal tube in
any desired position, the clip operating in the manner shown in Figs. 5 and 6.
Having now particularly described and ascertained the nature of my said
nvention and in what manner the same is to be performed, I declare that what 1
claim is :-
1. The improvements in gasaliers, electroliers and pendants whereby the same
may be raised or lowered substantially as herein before described and illustrated in
he several figures of the drawings and for the purpose set forth.
