PROVIDIONAL DIMITIVATION.
Improvements in Gas Chandeliers.
JAMES NATION MARTIN 21 Devonshire Road Greenwich in the County of
Kent Mechanical Engineer do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to prevent or minimise the fumes arising from gas
burnt in the usual & known way for lighting rooms, from discoloring the ceiling &
walls of rooms in which the gas is burnt. At the top of the chandelier is a small
frame. Curved pipes preferable one on each side, one or more chains on each side
attached to the chandelier pass over a pulley or pulleys to the weights in the
ordinary way, other chains are attached to these weights & carried over pulleys &
through preferable curved pipes. At the end of the pipe or pipes I connect other
tube or tubes, to which glass shades are suspended for shielding the ceiling & walls
of the room from the gas smoke or fumes, thus the chandelier can be moved up or
down or turned to any position & the glass shades will always keep the same
distance from the light, guides are attached to the weights which prevent them from
swinging or coming in contact with the shades. The shades act as reflectors &
improve the light thrown into the room.

COMPLETE SPECIFICATION.
Improvements in Gas Chandeliers.
I, JAMES NATION MARTIN 21 Devonshire Road Greenwich S.E. Mechanical
Engineer 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 :-
The object of my invention is to prevent or minimise the fumes arising from gas
burnt in the usual and known way for lighting rooms, from discolouring the ceiling
and walls of rooms, in which the gus is burnt.
Referring to the annexed drawing
Figure 1 is a side elevation of my invention applied to a chandelier.
Figure 2 elevation showing glass shade and double pulley.
Referring to Figure 1 & 2
a are the glass shades which are attached to the chains b which pass through the
hollow arms or tubes c which are attached to the frame d carrying the pulley
wheels e&e. To each arm there are two pulley wheels running free on the same axis.
These chains b pass over the pulleys e and are then attached to the guide or frame f
or to the weights g; the chains pass over the pulley wheels el and are attached to
the chandelier i at j. The frame d is pivotally secured at k to the inlet pipe l. By
this arrangement it will be seen that when the chandelier is raised or lowered the
shades a will maintain the same distance between the globes m, as the shades a will
be raised or lowered according to the movement of the weights g.
The guide or
frame prevents the weights from swinging and damaging the shades a.
