PRETADIONAL DIMITIVATION.
Improvements in and connected with Electroliers and Incandescence
Electric Lamp Pendants.
We, HUGO HIRST, Electrical Engineer, and JOHN HILLERY COLLINGS, Electrician,
both of Nos. 69-71-88, Queen Victoria Street, in the City and County of
London, do hereby declare the nature of this invention to be as follows:-
Our invention relates to certain improvements in and connected with electroliers
and incandescence electric lamp pendants, and has for its object the utilisation
of the counterweight or counterweights which balance the body of the electrolier,
so that this or these may carry lamps suitably connected to the main circuit,
and still fulfil the function of a counterbalance.
In carrying our invention into effect we may use a single central counter-
poise or weight, carrying one or more lamps, and being supported by a double
conductor which is wound upon a spring drum concealed within the crown or
ceiling fixture. This conveys the current from the main circuit to the lamp or
lamps of the counterpoise and by means of a distribution plate fitted therein two
or more double conductors passing over suitable pulleys convey the current to
the lamp or lamps of the electrolier or pendant, which may be raised or lowered
at will without affecting the lights in either the counterpoise or electrolier. In
the case of using two or more counterweights, each fitted with lamps, the central
electrolier or pendant is connected to the main circuit by a double flexible con-
ductor mounted upon a spring drum. The ends of the flexible conductors form-
ing the cord suspenders of the counterweights are also fixed and connected within
the crown and pass over suitable pulleys so as to fulfil the dual function of
conductors and suspenders.
We may, to suit various conditions of adaptation, vary the connections, and
the relative positions and numbers of the parts, without departing from the
essential feature of our said invention, which is the utilisation of a counterpoise
or weight in an electrolier or pendant, as a support for an electric lamp or
lamps.

Electric Lamp Pendants.
We, HUGO HIRST, Electrical Engineer, and JOHN HILLERY COLLINGS, Electrician,
both of Nos. 69-71-88, Queen Victoria Street, in the City and County of
London, do hereby declare the nature of this invention and in what manner the
Price 8d 1

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement;
-
Our invention relates to certain improvements in, and connected with electroliers
and incandescence electric lamp pendants, and has for its object the utilisation
of the counterweight or counterweights that are used to balance the body of the
electrolier, so that this or these may carry lamps suitably connected to the main
circuit, still fulfilling the function of a counterweight or weights.
In order to render the description of our said invention clearly, we have
appended the accompanying two sheets of drawings, in which Figure 1 shows
a partly sectional view of an electrolier or pendant with two or more counter-
poises. Figure 2 is a modification showing one central counterpoise in elevation.
Figure 3 is a view of the spring drum, partly sectional to more fully illustrate
the connections, and drawn to a larger scale. Figure 4 Sheet 2 is a diagram
of the connections where two or more counterweights are used as independent
auxiliary lights. Similar letters of reference indicate corresponding parts through-
out the several views.
It is to be understood that the drawings are not executed to scale, but are
simply diagrammatic, because in practice the details are hidden as much as
possible by ornamentation.
In carrying our invention into effect we may use a single central counter-
poise or weight e Figure 2 carrying one or more lamps, and being supported
by a double conductor of flexible cable or wire f and by means of a suitable
distribution plate fitted therein, two or more double conductors ggl passing over
pulleys d d and e el convey the current to the lamp or lamps C of the pendant
or electrolier, which may be raised or lowered at will without affecting the
lights C or in the counterpoise or electrolier aforesaid. The conductor f is
wound round a drum b shown drawn to an enlarged scale by Figure 3, which
is controlled by a spiral spring under tension in a box a; the whole being en-
closed in the ceiling rose or box A. One end of the drum bis insulated so that
one conductor k may be attached to it as a body contact, and the other end ; to
a disc in connection with a spring brush or contact i, this portion being insulated
by a bush h. We do not confine ourselves to this especial mode of insulation,
so that the drum b be divided and insulated electrically to separate the two
ends of the flexible conductor f, and yet maintain the requisite amount of tension
and strength to enable the said conductor f to be wound upon said drum b.
In Figure 1, two counterweights are shown carrying lamps cc; the lamps C
of the electrolier or pendant being fed from a flexible conductor f wound upon
a drum controlled by a spiral spring within a box a as hereinbefore described.
The distribution plates or board is in this case enclosed within B so that the
current may pass in parallel circuit through the double flexible conductors gg¹
over the pulleys dde e¹ to the lamps cc', which may be multipliplied according
to the requirements of the installation.

Figure 4 is a diagram of the electrical connections in this method of adaptation,
in which m and n are respectively the and leads connected to the main
circuit and E is a switch controlling the whole. An ordinary switch or equiva-
lent enables the electrolier or pendant lamps C to be turned off, leaving those
of the counterweights cc¹ alight, and depending upon the switch E.
We may vary the number of counterweights and also may cause each or any
of them to be used as auxiliary lights still fulfilling the function of counter-
poises, and we may also alter the mode of connecting the parts, according to
different conditions of adaptation.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is;-
First. In electroliers and incandescence electric lamp mendants the method

page_text: of and means for utilising one or more counterweights or counterpoises as electric
lamp holders, independently of the lamps of the electrolier or pendant aforesaid,
substantially as herein described and shown by the appended drawings and
diagram.
Second. In electroliers and incandescence electric lamp pendants, the com-
bination of a spring drum carrying the electrolier suspended to the flexible con-
ductor, with one or more counterweights having attached electric lamps in
circuit with the electrolier or pendant lamps independently or otherwise sub-
stantially as herein described and shown by the drawings.
Dated this 10th day of January 1899.
