PROVISIONAL SPECIFICATION.
Improvements in Pendants for Gas and other Lights and Lamps.
1, WILLIAM BEAL, of Hill Street, in the City of Birmingham, Lamp and Gas
Fittings Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention consists of the hereindescribed improvements in pendants for gas,
electric, oil and other lights or lamps. The said pendants when constructed
according to this invention, enable the light or lights to be raised or lowered in a
vertical line without the pendant being fitted with any water or other gas tight
slide, and in case the chains cords or the like supporting the counterbalance weight
or weights should break, the said counterbalance weight or weights and the moving
part of the pendant will be effectually prevented from falling away from the fixerl
part of the pendant.
According to one arrangement of my invention as arranged for gas I provide
two vertical parallel tubes arranged at a short distance apart and connected
together at the top to a single tube or connection terminating at the top in the
usual ball and socket joint. The lower ends of these tubes are connected together
by a cross piece or fitting which may be provided with two or more branching
arms carrying the gas lights, or these branching arms may be omitted. Jointed to
the lower ends of the said two vertical tubes are two small downwardly projecting
tubes both of the same length and to the ends of these are jointed two short tubes
of about the same length the lower ends of these last named two tubes being
jointed close or nearly close together to the upper part of a pendant gas lamp to
which the gas is conveyed through the said vertical tubes and smaller tubes..
It will be seen that this arrangement of the four smaller tubes permits of the
pendant gas lamp being raised or lowered the said smaller tubes turning outwardly
when the pendant gas lamp is raised and turning inwardly when the same is
lowered. In order to counterbalance the pendant gas lamp and more perfectly
guide the same up or down in a vertical line I provide a central tube or rod which
is fixed to the bottom fitting where the two lower tubes are jointed and is carried
upwardly through a guide at the bottom of the vertical tubes to a cross head or
slide between the vertical tubes and is there connected to two chains cords or the
like which pass over guide rollers at the bottom of the pendant and are led down
and fixed to a counterbalance weight which is free to slide up or down the vertical
tubes the said slide on the top of the vertical tube or rod being made small
enough to pass through the counterbalance weight. Or instead of a single central
counterbalance weight for the two chains each chain may have a separate counter-
balance weight. Or instead of employing any counterbalance weight or weights
I may counterbalance the weight of the moving parts by means of a coiled or other
spring or springs.
In a modification of my invention instead of the two vertical tubes I employ a
central tube to which the upper ends of the two upper shorter tubes are jointed;
and in a further modification of my invention I dispense with the central tube or
guide and connect the counterbalance chains to the fitting at the lower ends of the
lower smaller tubes.
Any of the arrangements above described may be employed for carrying a
pendant gas lamp from one end of one of the arms of any ordinary gas pendant one
of the other and opposite arms of which is counterweighted.

page_text: When my said invention is constructed for electric lights or for oil lights the
parts above described as being tubular may be made as solid tubes or bars as no
gas will have to pass through them as in the gas pendant above described.

I, WILLIAM BEAL, of Hill Street, in the City of Birmingham, Lamp and Gas
Fittings Manufacturer, 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 consists of the hereindescribed improvements in pendants for gas,
electric, oil and other lights or lamps. The said pendants when constructed
according to this invention, enable the light or lights to be raised or lowered in a
vertical line without the pendant being fitted with any water or other gas tight
slide, and in case the chains cords or the like supporting the counterbalance weight
.or weights should break, the said counterbalance weight or weights and the moving
part of the pendant will be effectually prevented from falling away from the fixed
part of the pendant.
I will describe my invention by referring to the accompanying drawings on which
Fig. 1 is a side elevation of a pendant constructed according to this invention
and arranged for an oil lamp;
Fig. 2 shews the same pendant extended;
Fig. 3 shews a modification of the same;
Fig. 4 is a plan of the balance weight part of the same separately;
Fig. 5 is a side elevation of a further modification arranged for
gas and
Fig. 6 shews how my invention can be used with an existing gas pendant.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawings.
According to one arrangement of my invention as arranged for carrying an oil
lamp (see Figs. 1, 2 and 4) I provide two vertical parallel tubes A' A² arranged at
a short distance apart and connected together at the top to a single tube or
connection B terminating at the top in the usual ball and socket joint C. The
lower ends of these tubes A1 A2 are connected together by a cross piece or fitting D.
Jointed to the lower ends of the two vertical tubes A' A² are two small downwardly
projecting tubes E¹ E² both of the same length and to the ends e of these are jointed
two short tubes F' F2 of about the same length as the two tubes E' E² the lower
ends of these last named two tubes being jointed close or nearly close together to
the upper part of a pendant oil lamp. It will be seen that this arrangement of the
four smaller tubes E' E F F2 permits of the pendant oil lamp being raised (see
Fig. 1) or lowered (see Fig. 2) the said smaller tubes surning outwardly when the
pendant oil lamp is raised and turning inwardly when the same is lowered. In
order to counterbalance the pendant oil lamp G and more perfectly guide the same
up or down in a vertical line I provide a central tube or rod H which is fixed to
the bottom fitting where the two lower tubes F1 F2 are jointed and is carried
upwardly through the guide D at the bottom of the vertical tubes A¹ A² to a cross
head or slide K between the vertical tubes A' A' and is there connected to two
chains cords or the like L' L' which pass over guide rollers M1 M² at the top of
the pendant and are led down and fixed to a counterbalance weight N which is free
to slide up or down the vertical tubes A' A the said crosshead or slide K on the
top of the vertical tube or rod H being made small enough to pass through the

page_text: central hole n¹ in the counterbalance weight N. Or instead of employing a single
central counterbalance weight N for the two chains L¹ L² each chain may have a
separate counterbalance weight as in an ordinary gasalier.
In the modification of my invention shewn by Fig. 5 instead of the two vertical
tubes A¹ A² I employ a central tube O to which the upper ends of the two upper
shorter tubes E' E are jointed and I connect the counterbalance chains L' L2 t,
the fitting I at the lower ends of the lower smaller tubes F¹ F³.
When a greater range of movement is required than can conveniently be obtaine
by using the two pairs of short tubes E' E2F1 F2 as above described and shewn by
Figs. 1 and 2 then four six or more pairs of the said short tubes may be used and
the range of movement correspondingly increased, for instance as shewn by Fig. 3
where the oil pendant is provided with four pairs of the said tubes jointed together
and marked respectively E' E², F¹ F³, E³ E*, F³ F¹.
Instead of using the four short tubes E' E' F1 F2 for suspending the oil or gas
lamp as above described two only of these tubes may be used as for instance E F
as shewn in the modification illustrated by Fig. 6. In this case the lower fitting I
at the top of the pendant oil or gas lamp is made with an arm Q' and counterbalance
weight Qas shewn so as to counterbalance the tubes E¹ F¹.
When my invention is arranged for a pendant gas lamp the gas is conveyed
through the ball and socket joint C and upright tubes A' A² (or single tube O)
and through the tubes E¹ E2F1 F2 to the pendant gas lamp (or the gas may pass only
through one of the upright tubes say A' and through the two tubes E F to the
gas lamp). When my invention is constructed for use with oil lamps as shewn in
Figs. 1, 2 and 3 or for the electric light then the parts above described as being
tubular may be made as solid tubes or bars as no gas will have to pass through
them.
Instead of or in addition to employing the crosshead or slide K for guiding the
tube H in its vertical movement between the tubes or rods A¹ A2, the guide rod or
tube S may be employed for the same purpose (see Fig. 6) this guide rod or tube S
being fixed at the top to the connection B and entering the tube H so that the
latter will slide up and down the tube or rod S.
Any of the arrangements above described may be employed for carrying a
pendant gas lamp from one end of one of the arins of any ordinary gas pendant
as shewn for instance by Fig. 6 where my improved gas pendant is connected to
one end of one of the arms P1 P2 of the ordinary T-pendant shown the other
arm P2 of which is counter weighted by the counter weight R made heavy enough
to counterbalance the pendant gas lamp hanging from the other arm Pl. By this
arrangement as shewn by Fig. 6 the pendant gas lamp can be swung round with
the pendant so as to be placed in various positions and it can also as above described
be raised or lowered vertically thus enabling anyone using the pendant to place the
lamp in the position which is best suited to give the light required.
It will be seen that by constructing a gas pendant according to this invention as
above described the light or lights can be raised or lowered in a vertical line
without the pendant being fitted with any water or gas tight slide, and moreover if
the chains or cords L' L2 or the like supporting the counterbalance were to break,
the counterbalance weight will be effectually prevented from falling away from the
fixed part of the pendant as it will only slide down and rest upon the fitting D and
the other part of the pendant will only fall down as far as the short tubes or
arms E E2 F1 F2 will allow and will not become detached from the fixed
part A A² of the pendant.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In pendants for gas and other lights and lamps the improved means for
supporting the light or lamp and for guiding the same for vertical movement, that
is to say, the combination of the two parallel vertical tubes or rods A' A² connected

page_text: together at their lower ends, the short tubes or rods E¹ E2 jointed thereto, the
short tubes or rods F1 F2 jointed respectively to the outer ends of the tubes or
rods E' E' and to the top of the pendant lamp or light, the vertical guide tube H
arranged and guided between the tubes A' A2 for vertical movement and provided
with chains or the like and a counterweight or counterweights all substantially as
described and illustrated by Figs. 1 and 2 of the accompanying drawings.
2. In a pendant constructed as denoted under claim one the arrangement of the
counterweight made to slide up and down the pendant and arranged with a central
hole for the cross head or slide to pass through.
3. In pendants for gas and other lights and lamps the combination of the two
parallel tubes or rods A' A² connected together at their lower ends, the two short
tubes or rols E' E jointed thereto, the two short tubes or rods F1 F2 jointed
respectively to the outer ends of the tubes or rods E' E' and to the top of the
pendant lamp or light, the counterbalance chains L' L2 passing over guide
pulleys M M and connected to the top of the pendant lamp and provided with
a weight or weights so as to counterbalance the same substantially as herein
described with reference to Figs. 1, 2 and 5 of the accompanying drawings.
4. In pendants for gas and other lights or lamps the combination and arrange-
ment of parts forming the means for supporting the lamp or light and for guiding
the same for vertical movement arranged substantially as herein described with
reference to Fig. 3 of the accompanying drawings.

vertical tube O, the two short tubes or rods E' E' connected thereto the two
short tubes or rods F1 F2 connected to the tubes or rods E' E2 and to the top of
the pendant lamp or light, the counterbalance chains L' L2 passing over guide
pulleys M' M² and connected to the top of the pendant lamp and provided with a
weight or weights so as to counterbalance the same substantially as herein described
with reference to Figs. 5 of the accompanying drawings.
6. In pendants for gas and other lights or lamps the combination of the two
parallel tubes or rods A' A' connected together at their lower ends the two short
tubes or rods E' F' jointed together and to the lower end of one of the tubes or
rods AA and to the top of the pendant light or lamp respectively the counter-
balance QQ to counterbalance the tubes E F, the vertical guide tube H
arranged and guided between the tubes A' A' for vertical movement and provided
with chains or the like and a counter weight or counter weights all substantially as
herein described and illustrated by Fig. 6 of the accompanying drawings.
