in Connection with Steam Boiler and other Furnaces.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings in the County of Middlesex 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 :-
My present invention comprises certain improvements in the apparatus described
in the specification filed with my application for Letters Patent dated February 14th
1887 No. 2316, whereby, instead of the several sprinkling devices described in said
specification I am enabled to use, a single sprinkling device consisting of arms
mounted upon a central hub and perforated, preferably upon one side, whereby, by
the force of the water issuing from said perforations, said arms may be revolved
and the water thus thoroughly distributed throughout the entire interior of the
condenser, as will be hereinafter more particularly described.
In the accompanying drawing, in which similar letters of reference indicate
similar parts.
Figure 1 is a central vertical section of a smoke-condenser and adjacent parts, when
it is arranged in position in connection with a furnace and boiler, on the dotted
line 1. 1 in Figure 2, and Figure 2 is a horizontal sectional view looking downwardly
from the dotted line 2, 2 in figure 1.
In said drawing;
A represents a furnace and boiler; B the breeching or conduit leading from said
furnace to the condenser; C the body or casing of said condenser; D the water
supply-pipe, and E, the revolving hollow-armed spider which is the feature of my
present invention.
Said several parts are all either of an ordinary and well known construction or are
shown and described in my aforementioned specification and, not being features of
my present invention, will not be further described herein except incidentally in
describing the invention.

The revolving spider E consists of a number of hollow arms (four are shown)
connected to a central hub mounted upon or connected to the inner end of the water
supply-pipe D, said arms are preferably formed of ordinary pipe and should be each
perforated upon one side so that the water issuing therefrom will cause them to revolve
in a manner which will be readily understood. This, as will also be readily seen,
distributes the water very thoroughly over the entire interior space of the condenser,
and thus accomplishes by this single device what I have heretofore accomplished by
a larger number of devices, and at the same time in a manner which is not at all
expensive as compared with other constructions.
By a reference to figure 1 of the drawing it will be seen that this water distributing
device is arranged entirely above the opening through which the products of com-
bustion enter the condenser from the breeching or conduit B and thus the water
issuing therefrom is precipitated upon all said products of combustion, and, forcing
them down, assists to form a vacuum for the continued inflow of products of com-
bustion. I may, and preferable do, employ a cross-bar E', which extends across the
condenser directly underneath the revolving spider and the inner end of the water
supply pipe as a support, thereby securing greater stability to the structure.
The operation is as follows. The products of combustion are drawn from the
furnace by the fan B³, and forced into the condenser. They are there subjected to a
thorough wetting from the spray or fine stream of water which issue from the
revolving spider. The gases are thereby purified and the solids are wet, and washed
down to the bottom of the condenser, whence they run off with the water and are
discharged into a sewer or other suitable place. The atmosphere of the neighbour-
hood where the furnaces are located is thus freed from impurities, and all danger of
fire from flying sparks is obviated.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
First In a smoke-condenser, a spider consisting of perforated hollow arms
extending out from a central hub which is secured to or mounted upon the water
supply-pipe, which extends into the condenser.
Second The combination, in a smoke condenser, of a water supply-pipe, a spider
consisting of hollow arms, and a central hub mounted and adapted to revolve on said
pipe, said arms being perforated upon one side and thus adapted to be operated by
the force of the water issuing therefrom.
Third The combination of a furnace, a smoke-condenser, a breeching or conduit
leading from said furnace to said condenser, a water supply-pipe entering said
condenser, and a series of perforated pipes connected with said water supply-pipe and
located in said condenser above the opening therein which communicates with the
breeching or conduit, substantially as shown and described.
Fourth The combination of a furnace, a smoke-condenser, a breeching or conduit
leading from said furnace to said condenser, a water supply-pipe entering the upper
portion of said condenser and extending to a central point above the opening which
leads from said conduit into said condenser, and a spider consisting of a series of
perforated radial arms and a central hub mounted upon the lower end of said water
supply-pipe, substantially as shown and described.
