Improved Cleansing Apparatus for Steam Boilers.
I, JOHN WILLIAM TAYLOR, of Harrods Cottages, Southend Road, Stanford le Hope,
Essex, Engine Driver, 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 :-
The objects of this invention are ;
1. To remove the sediment from the internal bottoms of steam boilers by the
internal pressure of the water and steam by means of perforated pipes fitted at the
lower part and having an outside tap, which when opened, permits an easy cleansing.
2. To collect the scum in a receiver from the surface of the water and to withdraw
the same by means of a perforated pipe and draw off cock.
For the purpose of the first part of my invention, I fit pipes in the lower part of a
boiler, whether it be Locomotive, internal firing, such as a Cornish or Lancashire, or
a Vertical boiler, said pipes being perforated, so that when a cock is opened from
the outside, tho internal pressure of steam will act upon the water and cause the
water to pass through the perforated pipes and carry the sediment through with it.
This part of my invention will be understood by reference to Figures 1 and 2 of
the annexed drawings, at Figure 1 I show a sectional plan view of a Locomotive
hoiler with pipes A, A, arranged round the lower part of the fire box, as seen in the
. longitudinal sectional view, Figure 3 said pipes A being perforated as to draw the
sediment from all round the fire box. B is the tap, which when opened allows of
the flow.
At Figure 2, I show a circular boiler, in which, I fit pipes in sections of ring
form and to enable the said pipes to be fitted in place, I pass them through the mud
hole and since said pipes cannot be screwed when being put in place, I fit a tight
fitting collar C over the adjoining ends and clamp the connection thereto by
scrow bolts.
In the case of a Cornish, or like boiler, I fit a straight pipe A for the length of
the boiler, as at Figure 4, but the shape of the pipe will depend upon the formation
of the boiler, within which, it has to be fitted and if desired more than one pipe may
be in connection by a single tap on the outside.
D is a perforated pipe at the upper part of the boiler, preferably just below the
ordinary water level. This pipe is partly surrounded by a ☐ shaped pipe E forming
a kind of hood with a distance between it and the pipe D and is also perforated for
the passage of scum into the chamber between D and E where it accumulates, so that
by opening the cock F, the pressure of steam will force the accumulated scum from
the chamber in E out through the pipe D. The taps B, F, being opened periodically
will retain the boiler free from accumulations of sediment at the bottom and of scum
at the top. It will also keep the water clean and prevent priming and the boiler
from being corroded.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The employment of perforated pipes A in the lowest part of a steam boiler, said
pipes having a tap in connection, so that sediment or dirt which precipitates in the
boiler, can be withdrawn as desired and as described with reference to the annexed
drawings.
2. The perforated hood E in connection with a perforated pipe D for the collection
and removal of scum from the surface of the water in a steam boiler, as described
with reference to the annexed drawings.
3. The improved cleansing apparatus for steam boilers as above described and as
shown in the annexed drawings.
