Improvements in Apparatus for Washing or Scrubbing Gas.
We,' SIDNEY HERSEY, Engineer, and KIRKHAM HULETT & CHANDLER,
LIMITED, all of 3 and 4, Palace Chambers, Bridge Street, in the City of
Westminster Gas Apparatus Manufacturers, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in apparatus for washing or scrubbing
gas, the object being to obtain a large amount of wotted surface by means of a
simple aud economical construction.
ז
For this purpose we construct discs of segmental bundles each made up of laths
placed one abovo another edgewise, the laths, as they approach the lower end or
centre. becoming gradually shorter in length. The upper laths of each bundle are
threaded on horizontal bolts, with distance pieces between them, and the rows of
laths are connected into a 'bundle end wise by means of end plates and a central
bolt. In some cases distance pieces are placed between the edges of the laths‹ŝo as
to leave spaces between their edges.
Instead of 'the lath's being connected.into bundles as above described, we sometimes
employ a slotted metal plate for each bundle, the lathe passing through the, slots
and horizontal pins passing through each row of laths and the plate so as to keep
the parts in position. The upper part of the slotted plate,is advantageously formed
with a handle to facilitate the manipulation of the bundle.
A number of our segmental' bundles are built up into a disc, and a series of
these discs are mounted on a 'shaft and revolved in a chamber as usual.

"Improvements in Apparatus for Washing or Scrubbing Gas.
"We, SIDNEY: HERSEY, Engineer, and KIRкнAM, 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 or scrubbing
gas; the object being to obtain a large amount of wetted surface by means of a
simple and economical construction.
For this purpose we construct discs of segmental bundles each made up of laths
placed one above another edgewise, the laths as they approach the lower end or
centre becoming gradually shorter in length. "The laths are threaded on horizontal
balts in rowe or sections, with distance pieces between them; and the saveral rows
or sections are connected into a bundle and wise by means ofvend plates, and a
central bolt. In some cases distance pieces are placed between the edges of the
laths so as to leave spaces between their edges.

page_text: Instead of the laths being connected into bundles as above described, we
sometimes employ a slotted metal plate for each bundle, the laths passing through
the slots and horizontal pins passing through each row of lathe and the plate so
as to keep the parts in position. The upper part of the slotted plate is
advantageously formed with a bandle to facilitate the manipulation of the
bundle.
A number of our segmental bundles are built up into a disc, and a series of these
discs are mounted on a shaft and revolved in a cbamber as usual.
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 side view of a segmental bundle constructed according, to our
invention; and,
Figure 2 is a side view shewing several bundles in position in a disc:
Figure 3 is a section on the line 3-3, Figure 2 :
Figure 4 is a view similar to Figure 3 illustrating a modification wherein the
central bolt is dispensed with and side segmental plates are employed :
Figure 5 is a section on the line 5-5, Figure 4:
Figure 6 is a side view illustrating the modification of the invention wherein
slotted metal plates are employed; and,
Figure 7 is a section on the line 7-7, Figure 6:
Similar letters of reference indicate corresponding parts in the several figures.
a, a indicate the segmental bundles and b, b are the laths of which they are
composed.
As shewn in Figures 1 to 3 the several laths of each row or section are
connected together by the horizontal bolts c, c (distance pieces c', c' being arranged
upon the bolts between the laths) and the several sections are connected together
by the longitudinal' bolt & which latter passes through the two clamping plates e, f,
the plate having recessed lugs by means of which the segment may be engaged
with a transverse bolt g in the drum, the side plates of which are indicated by the
letter h, and the clamping barbeing provided with lugs having holes for receiving
fixing bolts i, i which pass through the plates and clamping bar f
In order to further ensure the retention of the segments in the drum we employ
retaining bars such as j, which are bolted to the two side plates of the drum
and are in contact with the uppermost section of each segment. k, k are the
distance pieces which are arranged between the several sections, the longitudinal
bolt d passing through the said distance pieces in order to retain them in their
proper positions relatively with the sections.
In the modification of our invention shewn in Figures 4 and 5 the several
sections are held in position by means of side plates 1,1, the transverse bolts c, e for
fixing the several laths of each section being passed through the said side plates.
As in this modification the clamping bar e and the longitudinal bolt d are dispensed
with, we retain the segments in place by forming notches, on the lower ends
of the side plates 1, 1, and we provide transverse bars and for fixing the sections
in position between the sides of the drum as before. In this modification it will
be obvious that the distance pieces k, kare unnecessary.
In the modification of our invention shewn in Figures 6 and 7 the laths in each
bundle instead of being separated by distance pieces are inserted into slots in a
frame or plate m, the laths being retained in their slots by transverse pins n, n
which when the segments are inserted between the sides h, of the drum are
prevented from becoming displaced owing to their contact with the said side
plates h, h. In order to permit of the passage of water botween the several' sections
slots o, o are formed in the plates m, m.
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, a disc composed of a series of

page_text: segmental bundles each of which is composed of a series of laths placed edgewise
one above the other, substantially as described.
2. In an apparatus for washing or scrubbing gas wherein segmental bundles
having a series of laths placed edgewise are employed, retaining the laths by
transverse bolts to form sections and uniting several sections by means of a
longitudinal bolt or bolts to form bundles, substantially as described by reference
to Figures 1 to 3 of the accompanying drawings.
3. The modification of our invention wherein the longitudinal bolts are dispensed
with, the several lath sections being held between suitable side plates substantially
as described by reference to Figures 4 and 5 of the accompanying drawings.
4. The arrangement of our invention substantially as described by reference to
Figures 6 and 7 of the accompanying drawings wherein the bars are carried in
slots in a plate or frame, as set forth.
