AN IMPROVED APPARATUS FOR SEPARATING AND COLLECTING SOOT FROM THE SMOKE OF CHIMNEYS, AND FOR REMOVING THE SOOT SO COLLECTED
Year: 1884

page_text: I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Consulting Engineer and Patent Agent, do hereby
declare the nature of this Invention for "AN IMPROVED APPARATUS FOR
SEPARATING AND COLLECTING SOOT FROM THE SMOKE OF CHIMNEYS, AND FOR
REMOVING THE SOOT SO COLLECTED" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following.
statement:
This Invention consists in the combination, firstly, of apparatus for separating
and collecting the soot from smoke passing from a chimney; secondly, of arrange.
ments for removing the soot thus collected at the same time that the chimney is
swept and for preventing the rooms from being soiled at that time.
The construction and mode of operation of the apparatus will be readily
understood on reference to the accompanying Drawings in which Fig. 1 shews a
vertical section, Fig. 2 a sectional plan, Figs. 3, 4 and 5 cross sections taken
respectively on lines X X, Y Y, and Z Z. R is a tube forming the continuation of
the chimney flue, and which commences at U, is stopped short at the point a,
and is continued at some distance above at the point b. The tube is surrounded
by a casing M serving as collecting chamber for the soot, to the bottom of which is
attached a tube S by means of which the apparatus is fixed to the chimney while
the continuation R R2 of the tube R is attached to the top of the casing. The
tube R is capable of being moved up and down, being guided by bars B that pass
up into the fixed tube R' so as to slide in the same. To these bars is attached a
deflector D, consisting either of helical blades, as shewn, that will produce
centrifugal action upon the column of smoke rising up, and thus cause the solid
particles of soot to be thrown into the collecting chamber M, or the deflector may
consist of parabolic or other suitably curved blades that will direct the solid
particles outwards into the chamber M. The tube R with the deflector D can be
raised by means of a lever H, whereby an opening is formed at U, permitting the

page_text: soot that has collected on the sloping bottom of the casing M to fall down the
chimney into a receptacle below.
For cleansing the tube R, a brush C is provided consisting of separate parts as
shewn at Figs. 1 and 4, and which is suspended from a chain K and loaded with a
weight Q, so that on slacking the chain, it will be drawn down in the tube while
the spring arms will press the brushes against the sides of the tube, and thus
cause these to effectually clear the same of deposit. The central space between the
brushes is provided with flaps E that are connected to the chain K so that they
close down when the chain is slacked, and thus prevent the soot from being carried
upward by the draught. The chimney flue is provided at some point of its height
with a means for introducing a receptacle so as to shut off the lower part of the
chimney when the apparatus is being cleansed, thus protecting the rooms below
from soiling, and serving to catch the soot falling down, the receptacle being
afterwards closed by a cover and removed.
Other brushes may also be provided in the lower rectangular tube S as shewn at
Fig. 5, also to be moved up and down by the chain K.
For increasing the draught of the chimney a "Wolpert" cowl W is fixed on the
top of the tube R³, the construction of which will be readily understood from the
Drawing.
Having now particularly described and ascertained the nature of this Invention
and in what manner the same is to be performed, I declare that what I claim is :-
First: The construction of apparatus for separating and collecting the soot from
the smoke of chimneys, consisting of the combination of the moveable tube R,
deflectors D fixed tubes R1 R2 and casing M, arranged and operating substantially
as herein described, with reference to the accompanying Drawings.
Second: In combination with the apparatus for separating and collecting soot
from smoke, referred to in the preceding claim, the use of moveable brushes, such
as H for removing the adhering soot, a removeable receptacle or box in the chimney
for collecting the soot falling down, substantially as herein described.
