in apparatus for condensing steam
Year: 1887

page_text: We, OLIVER PERCY GRAY and WILLIAM GRAY, of "Shirley," Hastings, in the
County of Sussex, Merchants, 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 relates to improvements in apparatus for condensing steam and is
applicable to vats, coppers or other boilers from which, if open to the atmosphere, steam
would escape.
As the
The condenser consists of a conical or other suitably shaped dome having water
space all round it and adapted at its lower edge to be fitted to the rim of the copper
or vat. Near the base of the dome is an inlet for water and at the apex is an outlet
which may he connected with any suitable pipe for carrying off the water.
steam arises from the water in the copper or vat it comes in contact with the sides
of the dome which are kept cool by the fresh cold water continually circulating there-
through and the steam is condensed, whilst the condensing water is heated and may
be either conducted to a cooling tank or used as feed water for a boiler.
Figures 1 and 2 of the accompanying drawing illustrate two vertical sections of
a condenser constructed according to this invention and applied to an ordinary copper
or vat.
A is the condenser which is constructed of sheet metal or other suitable material and
consists of an internal and external casing a and a' between which is left a space B for
the circulation of water. The water enters at C and passes out at D the form of the
apparatus ensuring a thorough distribution of the water over the whole surface thereof.
Around the bottom of the condenser is a rim or flange E which fits into the rim of the
copper or vat F.
In Figure 1 handles G are shewn for enabling the apparatus to be readily moved
into or out of position. Where the size of the apparatus renders it too heavy to be
conveniently handled, pulleys H may be mounted on the exterior around which
cords or chains h which may be conducted over suitably arranged pullies fixed in
pass

suitable means.
The invention is not limited to the precise details of shape or construction herein
shown as these may be altered according to tho requirements of the purpose to which it
is intended to apply the same.
Having thus particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim, is:
1. A condensing apparatus consisting of a dome or cover such as A having two
walls a and a with water space between the same and provided with inlet and outlet
openings such as C and D substantially as described and illustrated in the accompanying
drawings.
2. A condensing apparatus such as described adapted to be fitted to the rim of
a vat or copper and provided with handles such as G or pulleys H for moving the
samo, substantially as described and illustrated in the accompanying drawings.
