PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Boiler Feed Water Heaters
and Puriflers.
I, SAMSON Fox of the Leeds Forge, Leeds, in the County of York, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to boiler feed water heaters and purifiers of the kind
composed of a number of sections each provided with a diaphragm or division
these sections being adapted to be bolted together, so that when in use the feed
water flows towards one end of the apparatus along the chamber under the
diaphragm or division then rises and returns along the chamber above the diaphragm.
Now according to my invention such feed water heaters and purifiers are made in
sections built up of suitably pressed or dished plates of mild steel rivetted together
with the centre diaphragm.
Each section is composed of two plates pressed or dished to channel form with
open ends and a flange all round; the longitudinal flanges are rivetted together,
a plain flat plate (with or without a suitable lip at one end) being inserted (before
rivetting) between the said two flanges thus forming a watertight partition and
dividing the section horizontally into two compartments.
By my invention I am enabled to obviate the liability to fracture and failure
which obtains with apparatus of the kind referred to when constructed of cast or
malleable metal.
Dated this 11th day of December 1890.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Boiler Feed Water Heaters
and Purifiers.
I, SAMSON Fox of the Leeds Forge, Leeds in the County of York, Civil
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 reference to boiler feed water heaters and purifiers of the
kind composed of a number of sections each provided with a diaphragm or division
these sections being adapted to be bolted together, so that when in use the feed
water flows towards one end of the apparatus along the chamber under the
diaphragm or division, then rises, and returns along the chamber above the
diaphragm.
Now according to my invention such feed water heaters and purifiers are made
in sections built up of suitably pressed or dished plates of mild steel rivetted
together with the centre diaphragm.
Each section is composed of two plates pressed or dished to channel form with
open ends and a flange all round; the longitudinal flanges are rivetted together, a
plain flat plate (with or without a suitable lip at one end) being inserted (before
rivetting) between the said two flanges thus forming a watertight partition and
dividing the section horizontally into two compartments.
In the accompanying drawings:-

page_text: Fig. 3 is an end view of a section of a feed water purifier made according to my
invention.
a and are respectively the upper and lower halves of the section of the purifier.
Each half, with its flange b' all round, is pressed or dished separately to the shape
shewn from a plain metal plate and the two halves with the interposed diaphragm r
are afterwards rivetted together as indicated at c. The diaphragm x is a piece of
plain flat plate.
The sections are secured together by bolts or webs passing through holes d in
the end flanges. By my invention I am enabled to obviate the liability to fracture
and failure which obtains with apparatus of the kind referred to when constructed
of cast or malleable metal.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
The manufacture of boiler feed water heaters and purifiers in sections of dished
or pressed metal plates with interposed diaphragm all bolted or rivetted together
as described with reference to and illustrated in the accompanying drawings.
Dated this 28th day of August 1891.
