IMPROVEMENTS IN WATER-SLIDE GASALIERS OR IN GAS CHANDELIERS
Year: 1885

page_text: I, WILLIAM SOUTTER of Farm Street Birmingham, in the County of Warwick,
Chandelier Manufacturer do hereby declare the nature of my invention for
IMPROVEMENTS IN WATER-SLIDE GASALIERS OR IN GAS CHANDELIERS and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
My Invention consists of a water indicator made of glass or other transparent
substance and so attached to the drop or down-pipe of the Gasalier as to be easily
removed therefrom for the purpose of cleaning or renewal. This invention will be
readily understood by reference to the accompanying drawings in which similar
letters represent similar parts in each figure.
A. Figs. 1. 2. 3. is a glass chamber having water communication with the drop
or down pipe b by means of holes c. c. c. The inner pipe d. d. Fig 1. is attached
to the ceiling in the usual manner. Water is poured in at the head of the down-
pipe b. till the chamber c. is filled. On the gasalier being drawn downwards a
vacuum is caused in the down-pipe b, on account of its recession from the inner
pipe d, which vacuum is filled up by water from the indicator a. So long as water
remains visible in the indicator a. no escape of gas can ensue, and danger of
explosion is thus avoided-I am aware that glass indicators for this purpose have
been previously used, but they have been made fixtures to the down-pipe b. either
by means of soldering on the caps or other methods--It has been found by
experiment that in constant use the glass indicator becomes so obscured by gaseous
secretions and other deposits as to render its removal necessary for cleaning
purposes.
This has hitherto been a source of expense and annoyance to the consumer
necessitating the employment of skilled labour.
The chief feature of my invention is to obviate this difficulty which I do by
means of screw caps and washers fully shewn in Figs 2 and 3. On the down-
pipe b. two screwed collars f. f. are fixed or made as a part of the down-pipe
Immediately between these and the glass indicator are placed the elastic washers g.g.
which pass by their elasticity over the screwed collars f. f. and fit the plain part of
the down-pipe b. The indicator a. having been placed in position the washers g.
are passed to their places and both firmly pressed against the top and bottom edges
of the indicator a. by means of the screwed caps e.

page_text: To entirely remove the Indicator a. it is necessary to unscrew the down-pipe b,
either from the body of the gasalier h. Fig 1. or from its funnel-shaped top-The
open ends of the Indicator a. are made sufficiently large to pass freely over the
screwed parts f. f.
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, In water slide gasaliers or gas chandeliers, the method of attaching indicators
of glass or other transparent substance to their drop or down-pipes by means of
elastic washers and screw caps or their equivalent, so as to render them easily
removable for cleaning or other purposes substantially as described and shewn in
the drawings.
