PROVISIONAL SPECIFICATION.
Improvements connected with the Apparatus for Raising and
Lowering the Centre Lights of Chandeliers and Electroliers,
also applicable to Brackets and like Fittings.
1, ROBERT HALL BEST of Cambray Works, Handsworth, Birmingham,
Chandelier Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention is applicable to similar fittings to those to which my Patent
No. 6907 of April 4th 1893 refers.
And consists in the separation of the extended portion of the crank arm to
which the counterpois weight is attached from the crank arm to which the
light is attached and the connection of these two arms by means of rods, chains,
cranks or other methods so that the light may balance in any position and when
applied to "pendants "that the pendant may hang plumb.
Dated this 9th day of March 1894.

Improvements connected with the Apparatus for Raising and
Lowering the Centre Lights of Chandeliers and Electroliers,
also applicable to Brackets and like Fittings.
I, ROBERT HALL BEST, of Cambray Works Handsworth, Birmingham,
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 :-
My invention is applicable to similar fittings to those to which my Patent
No. 6907 of April 4th 1893 refers; in the Specification of which, I describe the
employment of a fitting of the nature of a long crank, to one extended end of
which I attach the rod to which the lamp or other light is attached and to the
other extended end I attach a counterpoising weight so as to balance the lamp in
any position.
My present invention has for its object a further development of the adaption of
a counterpoise weight to balance this description of fitting in any position, and
consists in the separation of the extended portion of the crank arm to which the
counterpoise weight is attached from the crank arm to which the light is attached
and the connection of these two arms by means of rods, chains, cranks or other
methods so that the light may balance in any position, and when applied to
pendants so that the pendant may hang plumb.

The accompanying drawings will help to make clear the nature of my invention
and the manner in which I carry it into effect..
Fig. 1 is a representation of one form of my invention, applied to a suspension

page_text: lamp, shewing in dotted lines some of the various positions into which the light
may be placed.
Figs. 2 & 3 are representations of other forms of my invention.
(a) is the rod of the light (1), attached to the crank arm (c) by means of the
swivel joint or other suitable joint (b), the crank arm (c) being attached by means
of a swivel joint or other suitable joint to the descending rod (e) at (d), the rod (e)
is hung by the ordinary suspending screw or by the ordinary ball joint (f), the
counterpoise weight or weights (9) are carried by the crank arm (h) which is attached
by a swivel joint or other suitable joint (i) to the rod (e) above (or if desired
below) the joint (d) of the other arm (c). The arms (c) and (h) are then connected
by means of the chain (k) working over a pulley or wheel (w) on the rod (e),
see Fig. 1.
Or the fittings may take the form shewn in Fig. 2 with the crank arm (/) which
carries the weight (g) extended in the direction of (1) as in my Patent No. 6907
of the year 1893 but not directly supporting the rod (a) which carries the lamp (1),
this extended portion (h¹) of the arm () is then attached to the arm (c) by means
of a chain, links, cord, or the like (o).
Fig. 3 shews the arm (h) carrying the weight (g) connected by a crank (m) to
one end of a pivotted bar (p) the other end of this pivotted bar (p) having a
crank piece (n) attaching it to the arm (c) thus connecting the arms (c) and (h).
I wish it to be understood that I do not confine myself to the precise details
shewn upon the drawings, nor to the particular mode illustrated of attaching the
separate arms or portions (h) carrying the weights (9), and (c) carrying the
lamp (1), as I may vary these according to the requirements for the various
descriptions of lights or fittings to which may desire to apply this system of
adapting the counterpoise weight to lights capable of being extended into various
positions beyond the centre line of the fitting.
The advantage of this arrangement over that described in my former Patent
No. 6907 of 1893 is found in the fact that the separate arm and its joint takes the
strain of the counterpoise weight entirely off the joints which carry the light.
Having now particularly described and ascertained the nature of my said inven-
tion and what manner the same is to be performed 1 declare that what I
claim is :
1. In the raising and lowering of centre lights of chandeliers and electroliers
the employment of counterpoise weights carried by a separate arm or arms to that
which carries the lamp, the arms being connected by chains, cords, rods, cranks or
other means.
2. Applying the same system of counterpoise weight on one arm connected by
chains, rods, or cranks to an arm carrying a lamp or light, to pendant, standard,
or bracket lights.
