hereby declare the nature of my said invention to be as follows:-
This invention applies to the class of chandeliers and pendants hitherto used for
gas in which the weight of the chandelier or pendant is counterbalanced by chains
passing over pulleys to separate weights, or to a metal crown, the weights being
in all instances exposed to view. The object of this invention is to render such
chandeliers more compact and to entirely hide the generally ugly mechanical weight
arrangement, at the same time offering greater security from accidents and preven-
tion of evaporation of water, where an hydraulic arrangement is used for gas;
to adapt such gasaliers to electric lighting (Electroliers).
also
1. The separate parts of these improvements consist in making the counter-
balance weights to the chandelier or pendant of a long length of lead pipe such
as is used for water pipe which fits just loosely over the outer hydraulic tube when
used for gas, or over a plain tube when used for candles or electric light.
2. In the use of chain bands, or of textile bands in place of the ordinary chains,
for the suspension of the weights.
3. In the use of a pair of pulleys where one is ordinarily used to a single chain
or band to the counterbalance. The one pulley being placed above the other, the
lower pulley being used only to direct the band or chain inwards to the centre of
gravity of the counterbalancing pipe weight.
4. In providing a covering tube over the whole of the counterbalancing apparatus
described, which will be generally of an ornamental character.
5. In placing a collar or stop on the outer hydraulic or other tube, and a closing
collar upon the lower part of the new extra covering tube (4) so that if by accident
the bands should break, or rot, the chandelier could not fall, a ring of indiarubber
will be fixed above the closing collar of the outer tube to prevent jar.

of an insulated metal tube with a second tube or rod sliding therein sprung to
make contact when drawn out to any position. The chandelier will contain as
many such sliding tubes as there are conductors required, within the central tube ;
the chandelier arrangement being counterbalanced as described above.
These improvements are separately claimed when applied to chandeliers or
pendants. The whole will be generally applied to one chandelier for electric
light, and all except the last (6) for gas or candles.
The chandeliers will be made generally of brass and lead but other metals may
be used in place of these. The textile bands may be hemp, flax cotton silk or
wire or other material that can be plaited.

I, WILLIAM FORD STANLEY, of Cumberlow, South Norwood, Surrey, Engineer,
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:-
This invention applies to the class of chandeliers and pendants hitherto used
for gas in which the weight of the chandelier or pendant is counterbalanced by
chains passing over pulleys to separate weights, or to a metal crown, the weights
being in all instances exposed to view. The object of this invention is to render
such chandeliers more compact and to entirely hide the generally ugly mechanical
weight arrangement, at the same time offering greater security from accidents and
prevention of evaporation of water, where an hydraulic arrangement is used for
gas; also to adapt such gasaliers to electric lighting (Electroliers).
The separate parts of these improvements consist in
1. Making the counterbalance weight to the chandelier or pendant of a long
length of lead pipe such as is used for water pipe which fits just loosely over the
outer hydraulic tube when used for gas, or over a plain tube when used for candles
oil or electric light. The ends of the lead pipe will be lined with thin soft leather
to prevent friction.
2. In the use of chain bands, or of textile bands in place of the ordinary chains,
for the suspension of the weight.
3. In the use of a pair of pulleys where one is ordinarily used to a single chain
or band to the counterbalance. The one pulley being placed above the other, the
lower pulley being used only to direct the band or chain inwards to the centre of
gravity of the counterbalancing pipe weight.
4. In providing a covering tube over the whole of the counterbalancing apparatus
described, which will be generally of an ornamental character.
5. In placing a collar or stop on the outer hydraulic or other tube, and a closing
collar upon the lower part of the new extra covering tube, (4) so that if by accident
the bands should break or rot, the chandelier could not fall, a spring or a ring of
india rubber will be fixed above the closing collar of the outer tube to prevent jar.
6. In chandeliers or pendants for electric lights in forming each of the conductors
of an insulated metal tube with a second tube or rod sliding therein sprung to
make contact when drawn out to any position. The chandelier will contain as
many such sliding tubes as there are conductors required, within the central tube;
the chandelier arrangement being counterbalanced as described above.
The chandeliers here described suitable for all kinds of lighting will be made
generally of brass and of lead where so described but other metals may be used
in place of these. The textile bands may be hemp, flax, cotton, silk wire or other
material that can be plaitted or woven.
The parts of the invention are fully shewn in the drawings attached.

Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. The application of a long length of lead pipe fitting just loosely over the outer
or hydraulic tube of a chandelier or pendant to act as a counterbalance.
2. The suspension of such weight by textile bands or chain bands in place of
chains.
3. The use of pullies in pairs instead of singly to adjust the suspension to the
centre of gravity of the counterbalance weight.
4. A covering tube for counterbalancing apparatus of chandeliers or pendants.
5. A spring collar or stop on the above described covering tube.
6. Rods sliding in tubes to form conductors for Electroliers as shown within the
centre tube of a chandelier or pendant.
These parts of the invention are separately claimed. The whole may be applied
to one chandelier or pendant for electric light and all except the last claim (6) for
gas, candles, oil, or other chandelier or pendant. But the details may be varied
in form and parts omitted or others substituted still preserving the mechanical
principle as applied and described in this invention.
