We, ALBERT BROWN SCARBOROUGH, Banker, and JOHN ANDERSON BARNARD,
Banker both of Bonham, in the County of Fannin, and State of Texas, United
States of America, do hereby declare the nature of our invention for AN IMPROVED
APPARATUS FOR REMOVING SCUM AND MUD OR OTHER SEDIMENT FROM STEAM
BOILERS, to be as follows:-
This invention relates to means for cleaning the mud or foam, or both, from
steam-boilers; and it consists in the construction and novel arrangement of devices,
hereinafter described.
A pipe extends the length of the boiler at the water-line, and is connected to
the rear end of the boiler by a cup, held by a bolt. This end of the pipe is closed.
In the under side of the pipe are made, at certain intervals apart, a number of
small apertures, the aggregate area of all of these apertures being equal to the
area of the pipe-opening.
A bushing is connected to the threaded end of the pipe, this in turn being
connected to a nipple, and this to an elbow, to which the valve-seat, containing
the throttle-valve, is connected. A waste-pipe is connected to the valve-seat.
A similar pipe, also formed with under apertures and connected by a cup and its
bolt to the rear end of the boiler, extends along the bottom thereof about half an
inch from said bottom. This pipe may have an independent waste pipe and
throttle-valve, but is usually connected to the valve-seat of a common throttle-
valve, a three-way valve being provided to accommodate both the foam-pipe and
the mud-pipe. When the throttle-valve is opened, the foam will be forced through
the upper pipe, and the mud through the lower pipe, cleaning the boiler in a few
moments.

We, ALBERT BROWN SCARBOROUGII, Banker, and JOHN ANDERSON BARNARD
Banker, both of Bonham, in the County of Fannin, State of Texas, United
States of America, do hereby declare the nature of our invention for AN IMPROVED
APPARATUS FOR REMOVING SCUM AND MUD OR OTHER SEDIMENT FROM STEAM
BOILERS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference being had
to the accompanying drawing, and to the letters or figures of reference marked
thereon, which form a part of this specification:-
The figure of the drawing is a vertical sectional view of our device.
This invention has relation to means for cleaning the mud or foam, or both, from
steam-boilers; and it consists in the construction and novel arrangement of devices,
as hereinafter set forth.
In the accompanying drawing, the letter a designates a boiler having its water-
line at b. c, represents a pipe extending the length of the boiler at the water-line,
and connected to the rear end of the boiler by a cup, having the bolt, c. This
end of the pipe is closed. In the under side of the pipe are made, at certain
intervals apart, a number of small apertures, g, the aggregate area of all of these
apertures being equal to the area of the pipe-opening.
h. indicates a bushing, which is connected to the threaded end.. of the pipe, this
in turn being connected to the nipple el, and this to the elbow f, to which the valve-
seat 7, containing the throttle-valvez, is connected. The waste-pipe m. is connected
to the valve-scat. A similar pipe, c', also formed with under apertures and con-
nected by a cup and its bolt to the rear end of the boiler, extends along the bottom
thereof about half an inch from said bottom. This pipe may have an independent
waste-pipe and throttle-valve, but is usually connected to the valve-seat of a
common throttle-valve, a three-way valve being provided to accommodate both
the foam-pipe c. and the mud-pipe c¹. When the throttle-valve is opened, the
foam will be forced through the upper pipe, c, and the mud through the lower
pipe, c', cleaning the boiler in a few moments.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is
The combination, with a boiler, of the longitudinal cleaner-pipe having a series
of under perforations, the aggregate area of which is about equal to the area of the
pipe-opening, the cup and bolt connecting the closed end of the pipe with the boiler
end, and the throttle-valve and waste-pipe, substantially as specified.
