PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Raising or Forcing Hot Liquids.
I, MARK WILLIAM HOUSEHOLD of 38 Pershore Road, Birmingham in the County
of Warwick, Engineer do hereby declare the nature of this Invention to be as
follows:-
My Invention relates to apparatus of the kind described in the Specification of
Letters Patent No. 16051 granted to William Johnson as of the 8th day of December
1886 in the Specification of Letters Patent No. 10140 granted to me as of the 20th
day of July 1887 and has for its object to render the said apparatus capable of effect-
ing the cooling of the liquid discharged therefrom in a rapid simple and efficient
manner. This I effect by providing for the admission of air to the outlet or discharge
pipe of the apparatus.
According to my Invention I make an opening or openings through the outlet or
discharge pipe which I preferably enlarge at the part, where the said opening or
openings is or are formed and inside the said outlet or discharge pipe and opposite
the said opening or openings I fix a guard or liner forming a continuation of the
discharge passage and leaving a space between itself and the part of the outlet or
discharge passage in which the said opening or openings is or are formed the said
space constituting an air chamber closed at bottom but open at the top and there com
municating with the outlet or discbarpe pipe. When hot liquors are discharged from
the apparatus a current or currents of air enters or enter the air chamber and meeting
the liquid being discharged effects the cooling thereof.
Dated this 30th day of March 1889.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Raising or Forcing Hot Liquids.
I, MARK WILLIAM HOUSEHOLD of 38 Pershore Road Birmingham in the County
of Warwick 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 relates to apparatus of the kind described in the Specification of
Letters Patent No. 16051 granted to William Johnson as of the 8th day of December
1886 and in the Specification of Letters Patent No. 10140 granted to me as of the
20th day of July 1887 and my present Invention has for its object to render the said
apparatus capable of effecting the cooling of the liquid discharged therefrom in a
rapid simple and efficient manner I effect the object of my present Invention by
providing for the admission of air to the outlet or discharge pipe of the apparatus.
I will describe my Jnvention more particularly with reference to the accompanying
drawings in which Figure 1 shews in elevation an apparatus constructed according to
my Invention. Figure 2 is a longitudinal section and Figure 3 is a modification."
According to my Invention I make an air way or openings a through the casing A.
attached to the outlet or discharge pipe which casing 1 preferably enlarge (as shown)
at the part where the said openings a are formed and inside the said casing A and
opposite the said openings a I fix a liner B. which discharges the liquid from the
apparatus in to the main delivery pipe the space C between the liner B and the
casing A. constitutes an air chamber closed at the one end c but open at the other
end and there communicating with the outlet or discharge pipe which is secured at
the end a. When liquors are being discharged through the apparatus air enters the

cooling thereof. D is the casting containing the steam rozzle d flange d' for attach-
ment to the suction pipe and orifice d³ into which the end e of the delivery nozzle E
is inserted the parts D and E. being secured by bolts passed through, the flanges d'
and e. The flange b on the liner B. is received in a recess e in the nozzle E and it
and the part A are secured to the part E by bolts passed through the flanges a and e³.
Figure 3 shows a modification of the part D with the suction orifice-in-line.with tho
delivery orifice and the stean nozzle d passing through the side of the part D and
curved towards the delivery orifice, the nozzle having a flange by which it is secured
by screws passing therethrough and through the flange of the steam pipe and into the
part D.as shown.
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 claimais.
1. In apparatus of the kind described for raising liquids means for admitting,.air
to the said apparatus in the manner and for the purpose substantially as herein
before described.
2. In apparatus of the kind described for raising liquids the combination of casing A
perforated at a and provided with a liner B substantially as and for the purpose
herein before described and shewn.
3. The arrangement and combination of parts constituting a liquid forcing apparatus
as hereinbefore described and illustrated in the accompanying drawings.
Dated this 25th day of January 1890.
