Improvements in Apparatus for Washing or Scrubbing Gas.
We, SIDNEY HERSEY, Engineer, and KIRKHAM HULETT & CHANDLER,
LIMITED, Gas Apparatus Manufacturers, all of 3 and 4, Palace Chambers, Bridge
Street, in the City of Westminster, do hereby declare the nature of this invention
to be as follows:-
•
This invention relates to improvements in apparatus for washing and scrubbing
gas, the object being to prevent the escape of unwashed gas through the spaces
between the division plates and collar casting facings in gas washers of the kind
usually known as "The Standard Washer-scrubbers."
For this purpose round the centre opening of each division plate we bolt a ring
provided with an annular recess adapted to receive a spring or a number of springs
and a metal ring, which ring under the action of the spring or springs bears.against
the faced collar casting thus closing the space between the collar casting and the
division plate and thereby preventing the passage of unwashed gas.

We, SIDNEY HERSEY, Engineer, and KIRKHAM HULETT & CHANDLER,
LIMITED, Gas Apparatus Manufacturers, all of 3 and 4, Palace Chambers, Bridge
Street, in the City of Westminster, 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 :-
This invention relates to improvements in apparatus for washing and scrubbing
gas, the object being to prevent the escape of unwashed gas through the spaces
between the division plates and collar casting facings in gas washers of the kind
usually known as "The Standard Washer-scrubbers."
For this purpose round the centre opening of each division plate we bolt a ring
provided with an annular recess adapted to receive a spring or a number of springs
and a loose metal ring, which ring under the action of the spring or springs bears
against the faced collar casting thus closing the space between the collar casting
and the division plate and thereby preventing the passage of unwashed gas.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings, in which :-
Figure 1 is a vertical section of a portion of a standard washer-scrubber having
our improvements applied thereto :
Figure 2 is a side view of the drum and collar casting of the apparatus:
Figure 3 is a side elevation of our ring shewing the annular recess therein:
Figure 4 is a section drawn to an enlarged scale of a portion of the said ring
shewing the loose ring and one of its springs in position in the recess :

page_text: Figure 5 is a view shewing one of the springs in the recess, and,
Figure 6 is a horizontal section of the same.
u, a are the division plates of the gas washer-scrubber, is one of the drums
arranged between two of the said division plates; c is the faced collar casting
bolted to the drum by means of bolts d, d. e is the ring which we bolt to each
division plate in the central opening of the same, as shewn clearly in Figure 1.
fis the recess in the said ring, g is the loose metal ring which we place in the
recess f, and is one of the springs in the said recess which springs press the ring g
against the faced collar casting c. i, Figures 1 and 3, is a projection cast on the
ring e to limit the level of the water in the apparatus.
With the above construction it will be obvious that unwashed gas cannot escape
through the space between the division plate a and the collar casting c on account
of the tight joint made by means of the metal ring y which is kept in contact with
the facing of the collar casting by the springs h, h.
Having now particularly described. and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In apparatus for washing or scrubbing gas of the type usually known as
Standard washer-scrubbers providing each division plate with a ring round the
centre opening of the same such ring having an annular recess for receiving a loose
ring adapted to be pressed against the faced collar casting by means of a spring
or springs in the recess substantially as and for the purpose described.
2. The improvements in apparatus for washing or scrubbing gas hereinbefore
described and illustrated in the accompanying drawings.
