PROVISIONAL SPECIFICATION.
Improvements in Brackets for Gas and other Lights.
I, THOMAS FERGUSON, of 17 West Maitland Street, Edinburgh, in the County
of Midlothian, North Britain, Ironmonger, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in brackets for gas or other lights, to be
applied from the ceiling, floor, desk, wall or otherwise.
In accordance with my invention, I dispense with the usual central depending
pipe leading to the three or other number of radially arranged burners below, and
in lieu thereof I employ three or other number of depending pipes, according to
the number of radially arranged burners below, which are each bent outwards so as
to make a cage formation of the pipes, the pipes being brought together at the top
of the bracket where they are connected to the main gas supply, and also brought
together at the bottom of the bracket, the burners being radially arranged at
this part of the bracket, with a burner in a position between two of the bent
gas pipes.
By the said arrangement, a greater power of light is produced with the same
number and kind of burners, owing to the absence of shadow, which I achieve by
the said arrangement and construction of the pipes leading to the burners and by
the absence of the usual central gas supply pipe.
With the addition of a large reflector over the top of the bracket, a powerful
downward light is produced.
The burners may be provided with globes.

page_text: Figure 3 illustrates à cluster of five lights, and Figure 4 is a plan of the same.
The said lights are illustrated with regard to incandescent gas burners, with
funnels and globes.
As shown in the drawings I dispense with the usual central gas pipe or rod and
in lieu thereof I employ the three (Figures 1 and 2) gas pipes or rods B. B. B,
which supply the three burners A. A. A, the main gas supply being at C in the
present examples, and the clusters may also be suspended from C.
In Figures 3 and 4 the five gas pipes or rods B¹, B', B', B', B' supply the five
burners A', A¹, A', A¹, A.
Figure 5 shows the application of my invention to a two-light cluster, the
rods B being between the two globes, the said figure however only shewing the
one globe.
It will be seen that the burners or clusters are arranged radially between the
radially arranged supply pipes.
As shown in the drawings the gas pipes or rods are so arranged and brought
radially together at the top and bottom of the cluster as to leave a clear open space
in the centre of the cluster. By the said arrangement a greater power of light is
produced with the same number and kind of burners or clusters owing to the
absence of shadow, which I achieve by the said arrangement and construction of
the pipes leading to the burners and by the absence of the usual central gas supply
pipe. Also by my said improvements, the rods B become heated, and the gas
heated thereby produces a richer light; there is also economy thereby in the
consumption of gas.
With the addition of a reflector over the top of the bracket, a powerful downward
light is produced.
I would observe in conclusion I do not limit myself to any particular number of
burners to form a cluster, for example I may have a larger or smaller number of
burners than as shown in the drawings..
In applying my improvements to the electric light, the clusters would be turned
upside down so as to provide the ordinary pendant lights; in that case the
plug C, Figure 1, would be removed and the cluster suspended from C² instead of
from C.
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 :-
The improved cluster or arrangement of lights for gas and the like, substantially
as hereinbefore described and shown in the accompanying drawings.
Dated this 8th day of December 1894.
