Complete Specification Left. 16th June, 1896-Accepted, 18th July, 1896
I, ROBERT HALL BEST, of Cambray Works, Handsworth, in the County of
Stafford, Chandelier Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in electroliers of pendants for supporting
an electric lamp, my object being to so construct and arrange such electroliers as
to permit of the ready adjustment of the lamp to the required height without
obstruction from the connecting or current conveying wire fitted within the
pendant.
In carrying my invention into effect, I employ a socket tube constructed from
brass or other metal, and having brackets or arms formed with or attached to it
for carrying the chain pulleys which support the chain connecting the lamp with
the balance or counter weights in the ordinary manner.
The upper end of the socket is formed with a flange or head for attachment to
a loop or other connection by which the electrolier is suspended. I preferably
interpose a plate or disc of vuleanite or other insulating material between the
upper side of the socket head and the under side of the loop or other connecting
piece.
At the lower end of the socket I provide a square or other angular mouth or
aperture to admit a similarly shaped sliding tube or stem having the lamp with its
shade and other fittings attached to its lower or outer end.
2
The sliding tube can be thus caused to slide vertically within the socket
tube for adjusting the lamp to the required height, but it cannot be turned
or revolved within the socket. An internal coil of wire is placed within the
upper end of the socket for conveying the electric current to the lamp, one
end of the coil being secured to the sliding tube or stem, and the other end
to the upper part of the socket, the connection at each end being made by
means of a cord or wire grip of any suitable construction for preventing the
wire from twisting or turning. I thus provide for a free vertical movement of the
wire by the opening and closing of the coil with the downward and upward movement
of the lamp, but effectually prevent any jambing or entanglement of the coil within
the socket.
I do not limit the application of my invention to any particular form or pattern
of electrolier or pendant, but make such modifications in design and construction as
may be required for varying services.

page_text: Improvements in Electroliers.
I, ROBERT HALL BEST, of Cambray Works, Handsworth, in the County of
Stafford, Chandelier 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 relates to improvements in electroliers or pendants for supporting
an electric lamp, my object being to so construct and arrange such electroliers as
to permit of the ready adjustment of the lamp to the required height without
obstruction from the connecting or current conveying wire fitted within the
pendant.
In the accompanying sheet of explanatory drawings to be hereinafter referred
to.-
Figure 1 is a front elevation representing an electrolier constructed in accordance
with my invention, and Figure 2 a sectional elevation of the same.
Figure 3 is a sectional elevation of the electrolier showing the inner or sliding
tube drawn out from the outer or socket tube, a portion only of each tube being
shown.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect I employ a socket tube such as A constructed
from brass or other metal, and having a bracket or arms as B formed with or
attached to it in any convenient manner for carrying the chain pulleys C which
support the chains connecting the lamp with the balance or counter-weights D i
the ordinary manner.
The upper end of the socket tube A is formed with a flange or head for
attachment to a loop or other connection by which the electrolier is suspended, or
it has screwed on or otherwise directly attached to it a suspension shackle such
as E.
I close the lower end of the socket tube A preferably by a screw cap F, and I
form through the cap a square or other angularly shaped aperture to admit the
similarly shaped inner or sliding tube G which has the lamp H with its shade and
other ordinary fittings attached to its lower extremity.
The sliding tube can thus be caused to slide vertically within the socket tube for
adjusting the lamp to the required height, but is prevented from turning or
revolving during such movement.
Although I preferably employ an inner or sliding tube of a square or angular
section yet I sometimes adopt a round or circular tube for such purpose by forming
thereon a projection which slides through a corresponding slot in the cap F.
An internal coil of wire J is placed within the socket tube A for conveying the
electric current to the lamp one end of the coil being secured to the sliding tube or
stem G, and the other end to the upper part of the socket the connection at each
end being made by means of a cord or wire grip of any suitable construction for
preventing the wire from twisting or turning. I thus provide for a free vertical
movement of the wire by the opening and closing of the coil with the downward
and upward movement of the lamp, but effectually prevent any jambing or
entanglement of the coil within the socket. The wire does not terminate at either
end of the coil, the projection from the upper end being carried through the
shackle E, and the lower end drawn through the sliding tube G to be connected
with the lamp H.
I sometimes employ a separate length of wire for conveying the current through
the sliding tube G, and connect the upper end of the same to the lower extremity
of the coil.

as may be required for varying services.
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. An improved electrolier or pendant for supporting an electric lamp, consisting
in the combination of an inner and an outer tube and counter-balancing appliances,
with a wire coil arranged within the larger tube, substantially as and for the
purposes hereinbefore described.
2. In electroliers or pendants for supporting electric lamps, the use of a wire
coil such as J in combination with a socket tube A and sliding tube G, substantially
as and for the purposes hereiubefore described and as illustrated in the accompanying
drawings.
3. The improved construction and arrangement of electroliers or pendants for
supporting electric lamps, substantially as and for the purposes hereinbefore
described.
