PROVISIONAL SPECIFICATION.
Improvements in Appliances for Feeding Steam Boilers with an
Anti-incrustation Liquid.
1, BEN BOYES of 25 Naylor Street, Hanson Lane, Halifax in the County of
York, Factory Engineer do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in appliances employed for feeding or
charging the water in steam boilers with tannate of soda, or other alkalis or anti-
incrustation liquids for the purpose of preventing incrustation in such boilers, the
object being to provide apparatus whereby I am enabled to regulate the amount of
feed of the anti-incrustation liquid as required, and also to ascertain the amount of
liquid in such feeder, and to facilitate the charging of the feeders.
According to this invention I employ a metal receptacle or chamber which
contains the anti-incrustation liquid is placed therein by removing a screw plug, or
opening a valve. There is a passage way connecting each end of the chamber or
receptacle with the feed pipe of the boiler, and each passage way can be opened
or closed by tap or valve. A pressure or indicating glass or tube is fixed to the
chamber or receptacle and serves to shew the amount of incrustation liquid in
the said chamber, and a tap is provided at the bottom of the said chamber or
receptacle.
The action is as follows:-When the chamber is charged with the liquid, the
taps or valves on the passage ways are opened, and a proportion of the water
passing along the feed pipe to the boiler finds its way into the chamber or
receptacle, and its pressure gradually forces the anti-incrustation liquid through
the outlet passage way and so into the feed pipe and to the boiler. The tap or
valve and passage way at the inlet end of the chamber are slightly larger than at
the outlet end to obtain the required pressure.
To charge the chamber or receptacle the taps or valves on the inlet and outlet
passage ways are closed, and the tap at the bottom of the chamber opened to allow
the water to escape after which the liquid is inserted by way of the screw plug or
valve at the top.
By fixing the feeder to the boiler feed pipe one of such feeders will supply
several boilers.

Improvements in Appliances for Feeding Steam Boilers with an
Anti-incrustation Liquid.
I, BEN BOYES of 25 Naylor Street, Hanson Lane, Halifax in the County of
York, Factory Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
asco tained in and by the following statement :-
This invention relates to improvements in appliances employed for feeding or
charging the water in steam boilers with tannate of soda, or other alkalis or anti-
incrustation liquids for the purpose of preventing incrustation in such boilers, the
Pies 827

feed of the anti-incrustation liquid as required, and also to ascertain the amount of
liquid in such feeder, and to facilitate the charging of the feeders.
According to this invention I employ a metal receptacle or chamber which
contains the anti-incrustation liquid which is placed therein by removing a screw
plug, or opening a valve. There is a passage way connecting each end of the
chamber or receptacle with the feed pipe of the boiler, and each passage way can
be opened or closed by tap or valve. A pressure or indicating glass or tube is
fixed to the chamber or receptacle and serves to shew the amount of incrustation
liquid in the said chamber, and a tap is provided at the bottom of the said chamber
or receptacle.
Such being the nature and object of my said invention the following is a
complete description of same reference being had to the accompanying drawings in
which:-
Fig. 1 is a side elevation illustrating the improved apparatus as applied to a feed
pipe of a boiler, or to feed water or "economizer" the apparatus being drawn
about one quarter full size.
Fig. 2 is a front view of Fig. 1.
The receptacle or chamber 1 is charged with the anti-incrustation liquid through
the cup 2, the tap 3 being open, and the tap 4. 5 being closed. If the tap be
slightly open a short time the filling of the chamber 1 with the liquid is facilitated
wherein the taps 3 and 6 are both to be closed.
To put the
apparatus in operation the tap 4 is to be fully opened and 5 partially
opened, so that there is a greater surface pressure on the liquid in the chamber 1
than the resistance at the outlet from tap 5, and which inequality of pressure can
be regulated as desired by opening the tap 4 and 5 more or less accordingley as a
greater or less supply of the anti-incrustation liquid is desired the flow of the
anti-incrustation liquid from the chamber 1 is further facilitated by its specific
.gravity.
The quantity of liquid in the chamber 1 as also the quantity discharged therefrom
can at all times be seen and noted by means of the gauge glass 7. At 8 is a screw
plug on removal of which the gauge can readily be cleaned internally.
The improved apparatus may be placed on vertical or horizontal feed pipes such
as 9 and so may be used for purpose of supplying several boilers by one such
apparatus and it will be readily seen how by opening and closing the several taps
that at any time a flow of water through the apparatus for cleaning latter if
considered desirable may be effected.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved apparatus as and for purpose described and substantially as
illustrated by drawings annexed.
2. The chamber 1, gauge glass 7 taps 3, 4, 5 all in combination for purpose
herein described.
