Improvements in Steam Condensers.
We, LAWRENCE FARRAR GJERS, of Woodlands Road, Middlesbrough-on-
Tees, in the County of York, Engineer, and JOSEPH HUTCHINSON HARRISON,
of 2, Exchange Place, Middlesbrough-on-Tees, in the County of York; Engineer,
do hereby declare the nature of this invention to be as follows:-
It has reference to evaporative surface condensers, & consists of the use of a
shallow metal box, or a series of shallow metal boxes of suitable length, into which
steam is admitted, &. condensed. by the distribution of water over the external
surfaces of said box, or boxes.
The sides forming the condensing surfaces of each box, are placed only a very
short distance apart, are strengthened by internal stays, to prevent them from
collapsing by the external atmospheric pressure. The surfaces of each box may
be either flat, or they may be further strengthened by corrugations, or indenta-
tions, in any form, or gilled.
The inside of each box may be arranged, so that the steam passes straight
through, or it may be divided up into compartments, so as to give the steam a
zig-zag course, if desired.'

COMPLETE SPECIFICATION.
Improvements in Steam Condensers.
We, LAWRENCE FARRAR GJERS, of Woodlands Road, Middlesboro-on-Tees,
in the County of York, Engineer, and JOSEPH HUTCHINSON HARRISON, of
2 Exchange Place, Middlesboro-on-Tees, in the County of York, 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:-
This invention has reference to improvements in evaporative surface condensers
which we will now proceed to explain with reference to the accompanying
illustrative drawings, whereof
Fig. 1 shows in longitudinal section one construction of evaporative surface
condenser according to this invention;
Fig. 2 shows the same in transverse section; and
Fig. 3 shows the same in horizontal section.
AA are condensing boxes made shallow, that is, with the large sides thereof a
very short distance apart, and vertical or approximately so, in such manner that
these sides constitute the main condensing surfaces. These sides are formed of

page_text: thin metal (preferably brass or other metal of high conductibility) and are shewn
flat, but they may be corrugated, indented, or gilled to give greater strength. The
sides are also shewn stayed inside by ferrules and rivets to prevent collapse arising
from pressure of the external air but internal bars grids or shouldered and rivetted
tubes may be used for the same purpose.
Although three boxes are shewn grouped together, more may be added or there
may be fewer (even one only) according to requirement. B is a pipe whereby
steam to be condensed is conducted into an end box C whence it is distributed
into the condensing boxes A wherein it is condensed by means of cooling water
caused to flow over the outsides of the said boxes from the water troughs D to
which water is constantly supplied from water supply pipes E by valves F and
from which troughs such water overflows on to the condensing boxes. Air and
water of condensation pass into the end box G and can be drawn off by an air
'pump at the neck H.
A light shield J is provided to protect the water in the troughs D from the
wind. In lieu of these water troughs I) perforated pipes, jet or spray producers
may be substituted such as will give a practically even distribution of cooling
water over the larger sides of the condensing boxes.
Figs. 4 and 5 show an alternative arrangement wherein the condensing box is
divided up into compartments by internal partitions extending from near the
bottom towards the top and from near the top towards the bottom alternately to
give the steam a zig-zag course during its condensation.
Fig. 6 is a sectional view to a larger scale illustrating one method of constructing
the condensing boxes A represented in Figs. 1, 2 and 3.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
-claim is
An evaporative surface condenser comprising a shallow box or boxes (plain or
corrugated or gilled) and means for causing liquid to flow over the external
surfaces of such box or boxes as set forth so as to condense steam within the same
substantially as described and illustrated.
