PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Supplying Disincrustants to Steam
Boilers, Economisers, and the like.
JOHN ALFRED MORRIS and WILLIAM THOMAS HATCH, Engineers, both of
the Empire Works, 78, Great Bridgewater Street, Manchester, Lancashire, do
hereby declare the nature of this invention to be as follows:-
The object of our invention is to manufacture in an improved manner, an
apparatus applicable to steam boilers, economisers and the like for the purpose of
introducing disincrustants &c., into same.
Our instrument consists essentially of a reservoir to contain the fluid required to
be fed; one or two valves or plug cocks for the regulating of the ingress and egress
of the fluids; a run-off tap for withdrawing the residuum before refilling for the
next charge; and a stand for supporting the whole structure, this stand may be
placed directly under the reservoir when it is wished to connect to a horizontal
surface, or it may be placed at the side when attaching to a vertical one.
To enable a better regulation of the various motions, an indicator glass can be
placed at the side, or a sight glass can be arranged underneath the reservoir.
We arrange that the passage allowing the exit of liquid be placed as low as
possible in the instrument, whilst the one allowing the ingress of fluid (either liquid
or gaseous) be introduced (either internally or externally) as high in the reservoir
as possible.
We also make a point in the fact that there is only one connection between our
instrument and the steam or water pipe or boiler, to which it is fixed.

Improvements in Apparatus for Supplying Disincrustants to Steam
Boilers, Economisers, and the like.
John Alfred MORRIS and WILLIAM THOMAS-HATCH, Engineers, both of
the Empire Works, 78 Great Bridgewater Street, Manchester, Lancashire, 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 object of our invention is to enable liquid disincrustants or other liquids
having a different specific gravity to water, to be introduced into economisers,
boilers and water pipes for the purpose of removing scale or preventing its deposit,
or for other purposes for which it may be considered necessary to introduce other
liquids into water.
In the following description of the apparatus, its application to economisers or
service pipes with water in, is shewn; from which its application to analogous
purposes will be understood, reference being made to the accompanying drawings,
in which similar letters of reference, indicate corresponding parts.

"A" is a reservoir for containing the liquid disincrustant, it is filled through an
aperture closed by a plug B; C is a tube (shewn internally fitted, but may be
external if preferred) for introducing the feed water to the top of the reservoir.
D

page_text: D is a hole in plug E for allowing the disincrustant to escape; E is a valve or
plug, having two holes or passages made in it, the one (M) for admitting the feed-
water or other fluid into the reservoir, and the other (D) for allowing the
disincrustant or other liquid to escape. G is a screwed bush for compressing the
packing against plug E, and keeping same tight and in position. H is an indicator
glass which may (not necessarily) be fitted to the reservoir, to show the quantity
of contents. J is a passage communicating with the outlet D and conveying the
liquid released from the reservoir to the tube N, which delivers it into the feed-
water. K is the stand, screwed into the service pipe, and supports the whole
apparatus.
The illustrations show this at one side, to suit vertical pipe, but if the stand be
placed directly under the reservoir, the apparatus will be applicable to horizontal
pipes, without making any change in the principles affecting its working. L is a
bandle for moving plug E, thus opening or closing the passages and regulating the
supply of disincrustant. M is a tap or valve for releasing any liquid left in the
reservoir, previous to charging with a fresh supply.
The action of the apparatus is as follows, The handle L is placed in a horizontal
position, thus closing the inlet and outlet passages; plug B is removed and any
liquid drained off by means of tap M, this latter is then closed, and the reservoir
filled with the liquid required to be introduced into the feed-water, and plug B is
replaced. The handle L is turned into a vertical position, thus opening both
passages D and M; in a few moments the apparatus is under the same influence
and pressure as the water in service pipe, and the liquid or disincrustant being
heavier than water, sinks to the bottom and finds its way by gravity through the
passages J and N into the feed-water, whilst its place in the reservoir is taken by
an inflow of the feed-water through the stand K and passage M, up the tube Ċ
and ultimately into the reservoir A.
In cases where the disincrustant or other liquid is of a less specific gravity than
water, the apparatus can be arranged to have the reservoir below the level of stand
instead of above, as shewn in the illustrations, when the action will be similar to
that described above, with the exception of the liquid rising instead of falling into
the feed or service pipe.
Pressure baving no influence upon the action of the apparatus, it always resolving
itself into a state of equilibrium with the fluid with which it is connected, its
application is not limited to economisers or boilers, but service pipes under hydraulic
pressure, can be effectively dealt with in the manner already described.
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 :-
1st. The combination of a "feeder" with a single connection to the feed or
service pipe or boiler, substantially as hereinbefore described.
2nd. The combination of a "feeder" with a single connection to the feed or
service pipe or boiler, and having the "inlet" tube either internally or externally
fitted substantially as hereinbefore described.
3rd. The combination of an apparatus with a single plug for regulating and
shutting off the inlet and outlet passages, and a single connection to service-pipe,
main or boiler, for the introduction of liquids of a greater or less specific gravity
than water, substantially as herein before described.
