Feed Water Regulating Apparatus for Steam Boilers.
'
I, EDWARD CHARLES PECK, of 18, Victoria Road, Old Charlton, in the County of
Kent, Engineer, do hereby declare the nature of this invention to be as follows:-
Tho feed water regulating apparatus for steam boilers has a horizontal cylinder or
chamber which is placed near to the boiler, (whose supply of water is to be
regulated) and in such a position that the bottom of the inside is level with, and in
a line with, the normal water-line of the boiler. A pipe connects the lower part of
the cylinder or chamber with the water of the boiler, and another pipe connects the
upper part of the cylinder or chamber with the steam space of the boiler, and both
pipes are led from the centre of the cylinder or chamber reckoning from the ends,
and they are provided with cocks or valves to enable them to be closed, or
partially closed, when the boiler attendant may require to do so. In this cylinder
or chamber is a piston and rod; the former being either of a loose lit, or if fitting,
having holes in it, to permit of the water and steam in the boiler having access to
both ends of the cylinder. The area of these holes are made to suit the speed of the
pump. Instead of the piston being loose, or having holes in it, a suitable passage
may be provided, to form a means of communication between both ends of the
cylinder or chamber. The piston, and rod, are worked to and fro, by the latter
being attached to some suitable reciprocating part of the "feed pump." By this
arrangement of apparatus the quantity of water in the boiler will be regulated so as
not to be in excess of that required, for as soon as the water in the boiler reaches
the normal height, it is then at the level of the bottom of the cylinder or chamber,
and when this height is exceeded, the water flows into the regulating cylinder or
chamber, and comes into contact with the piston, and causes it, by its connection
with the feed pump, (which may be a tail rod attached to the pump rod) to retard
the speed of the said pump, and thereby lessen the amount of water delivered to the
boiler, until such time as the level of the water has been lowered to its correct
position.

Feed Water Regulating Apparatus for Steam Boilers.
I, EDWARD CHARLES PECK, of 18, Victoria Road, Old Charlton, in the County
of Kent, Engineer, 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 feed water regulating apparatus is designed to be attached to independent
food angines or donkey food-numns

page_text: Figure 1 of the drawing is an elevation of a vertical boiler with the feed water
regulating apparatus attached thereto and to a feed pump; the cylinder or chamber
of the apparatus being in section.
Figure 2 is a sectional view of the apparatus, and part of the vertical boiler.
(a) is the vertical boiler.
The apparatus has a horizontal cylinder or chamber (b) which is placed near to
the vertical boiler (a) (whos supply of water is to be regulated) and in such a
position that the bottom of the inside is about level with, and in a line with, the
normal water line (c) of the boiler. A pipe (d) connects the lower part of the
cylinder or chamber (b) with the water space of the boiler; and another pipe (e)
connects the upper part of the cylinder or chamber (b) with the steam space (f)
of the boiler (a), and both pipes (d) and (e) are led from the centre of the cylinder
or chamber (6), reckoning from the ends, and they are provided with cocks or
valves (g) and (h) to enable them to be closed, or partially closed, when the boiler
attendant may require to do so.
In the cylinder or chamber (b) is a piston (i) and rod (7), the former being
either of a loose fit, or if fitting having holes in it, to permit of the water and
steam in the boiler having access to both ends of the cylinder or chamber (b).
The areas of these holes are made to suit the speed of the pump. Instead of the
piston (i) being loose, or having holes in it, openings may be provided at each end
of the cylinder or chamber (b), and these connected by a pipe (m), as shown on
the drawings, which may have a cock or valve (n) conveniently placed in some
part of its length to permit of the regulation of the flow of steam and water from
one side of the piston (i) to the opposite side; or a suitable passage or by-pass
may be provided to form a means of communication between both ends of the
cylinder or chamber (b).
The piston (i) and rod (j) are worked to and fro by the latter being attached to
some suitable reciprocating part of the "feed-pump" used to supply water to the
boiler, such a pump (k) is shown on the drawing, supported by a bracket (/) attached
to the boiler.
Neither the boiler (a), feed-pump (k), nor bracket (l), are claimed as part of the
apparatus, as it may be used in conjunction with any form of steam boiler or suitable
feed-pump.
By the use of the arrangement of apparatus hereinbefore described the quantity
of water in a boiler can be regulated so as not to be in excess of that required, for
as soon as the water in the boiler reaches the normal height, it is then at the level
of the bottom of the cylinder or chamber (b), and when this height is exceeded, the
water flows into the regulating cylinder or chamber (b) and comes into contact with
the piston (i) and causes it by its connection with the feed pump (which connection
may be made by means of a tail-rod attached to the pump rod and the piston rod (j)
of the cylinder or chamber (b) to retard the speed of the said pump, and to thereby
lessen the amount of water delivered to the boiler until such time as the level of the
water has been lowered in the boiler to its correct position.
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 :-
