Improvements in Apparatus for Heating Water, Air, or other Fluids,
and Condensing Steam.
I JOSEPH WRIGHT of 16 Great George Street in the City of Westminster, Mechanical
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 :-
My Invention has for its object to provide apparatus wherein the heat of exhaust or
other steam is efficiently utilized in heating water air or other fluids there being several
heaters and a divisional groase tank (for the reception of the water of condensation)
in combination in the one apparatus from which heated water air or other fluid can
be drawn off for the various uses required in buildings houses factories or steam
vessels or in other places. I will describe my Invention with reference to the
accompanying drawings. Figure 1 is a longitudinal section Figure 2 a plan and
Figure 3 a vertical section (taken on a line 1. 2 Figure 1) of an apparatus arranged
according to my Invention. Figure 4 is an elevation of the vacuuin and relief valve
hereinafter described, and Figure 5 is an elevation of the end of the apparatus at
which the steam is admitted.
A is the pipe or passage for the steam which is employed as the heating agent.
The said steam may be the exhaust steam from engines or live steam or steam from
any suitable source. It may enter at a and its entry be controlled when desired by
means of a ported valve B consisting of a perforated outer part contained in the
casing & forming a passage around the valve for the entry of the steam which escapes
through the ports and valve into the outer casing 63. The part constitutes a cylinder
in which slides the inner part or piston valve c which is also perforated with ports so
that as the piston is moved vertically in the part 6 it covers and uncovers the ports
or openings so that the requisite quantity of steam passes, the quantity being cut off
and controlled by means of a cam d on a rotating shaft D which can lifts the valve
by acting on its rod c³ ³ and c are pads on the rod and casting c³ to come into contact
with each other to prevent noise and the piston valve from falling too far below the
outer ports. The lower ends of the tubes e of the heaters E open into the steam pipe
or passage A so that the steam passes through the tubes owing to the webs dipping
into the water below. These webs dip into the spaces within the conical dip pipes,
which are open, at bottom and suspended from the top flange in the tanks formed by
the division plates h. The outer tank K is in communication from the inlet end k to
the outlet end by means of the pipes ks. The water of condensation-from the steam
falls into the conical dip pipes g. 9. and thence rises up round about the outside thereof
between them and the plates A, and passes out by the openings h into the tank K. If
the water from the condensation of the steam be not sufficient to maintain the desired
level in the tank K, a ball cock or ball cocks, as at lopen, an inlet or inlets for water
to make up any deficiency and to replace water which may be drawn off at k. The
water passes eventually from the tank K by the outlet k it passing under the partition
plate to the outlet, the said partition plate serving the purpose of intercepting
grease or impurities floating on the water. In place of or in addition to, the
openings the communication between the spaces enclosed by the plates h and the
tank K may be made by an outside pipe as at H with branches opening into each such
Брасе. M is an automatic double ported piston reducing valve by which additional
steam can be admitted or cut off. It consists of a perforated cylinder m in which slides
a similarily perforated piston m² connected by the rod m³ with a bell m* dipping into
a water seat at m². When the pressure of steam is excessive the bell m* is caused to
rise and steam which was supplied at n is cut off and when the pressure decreases the
bell m falls and the supply of steam from n is reestablished. m is a chain by
weighting which the pressure at which the valve opens can be regulated at pleasure

page_text: and by which the valve can be operated by hand when desired. A valve of this
description can be used between any two of the heaters if so desired. I do not limit
myself to the use of three heaters as two or more may be employed. At the end of
the steam pipe or passage A is an automatic vacuum and relief valve P consisting of a
piston p and cylinder p perforated or ported as in the case of the valves B and M and
opening under any desired pressure (which may be regulated by the weighted rod and
lever p³) to relieve the said pressure but returning to its seat or closing the ports to
retain vacuum formed in the pipe or passage A. The valve P has an outer casing
formed with a passage pt there through for the accommodation of the weighted lever p³
and with an external passage p for the escaping steam leading to the uptake p³.
The compartments into which the tank K is divided are provided with covered hand
holes. The compartment for supplying water (either hot or cold) and provided
with the ball valve or valves / is open at top, compartment at the other end having
a covered top and being provided with a manhole 48. The diaphragm plate ko as
aforesaid prevents grease or other impurities floating on the surface of the water
from passing into the pump suction pipe k* such grease or impurities escaping through
the overflow pipes k.
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 arrangement and combination of parts constituting the apparatus for heating
water air or other fluids substantially as hereinbefore described and illustrated in the
accompanying drawings.
2. In apparatus for heating water air or other fluids an inlet ported valve arranged
and operating substantially as hereinbefore described with regard to the valve B.
3. In apparatus for heating water air or other fluids a valve for admitting or cutting
-off automatically as required a supplementary steam supply substantially as hereinbefore
described with regard to the ported valve M.
4. In apparatus for heating water air or other fluids a relief and vacuum valve
constructed substantially as herein before described with regard to the ported valve P.
5. In apparatus for heating water air or other fluids a multiple tank (K) containing
the lower chambers or water seals of two or more heaters and with communications
from the said lower chambers or seals to the said tank and communications from the
parts of the said tank so as to constitute it one tank common to all the heaters and with
the water inlet or inlets substantially as hereinbefore described.
