PROVISIONAL SPECIFICATION.
Improvements In Vessels for Heating Water by Means of Steam.
We, WILLIAM SHORE and GEORGE COUPÉ both of Shelton, "Hanley, in the
County of Staffordshire, Engineers, do hereby declare the nature of this invention
to be as follows':―
This invention relates to vessels for heating water by means of steam, the steam
being 'separated from the water to be heated, by tubes, the steam being on the
outside of the tubes; and the water passing through the tubes.
The invention consists of a method of breaking up the current of 'water as it
passes through the tubes by means of suitable deflectors which are suspended
inside the tubes.
The invention is carried out in the following manner. In vessels which are used
for heating water by means of steam, which steam surrounds a tube or +tubes; the
steam being confined by an outer casing, the casing having closed ends; but through
which the tube or tubes pass, it is found-that when the water to be heated is passed
through the tube or tubes, a certain portion of the water does not come in contact
with the tube surface, the object of the invention being to prevent this, which is
done by placing in the tube or tubes (at short intervals) metal discs or other
obstructions which break up the current of water, thus bringing more particles of
water against the surface of the tube.

We WILLIAM SHORE and GEORGE COUPE both of Shelton Hanley, in, the
County of Stafford, Mechanical Engineers 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 vessels for heating water, by means of steam, the steam
being 'separated from the water to be heated by tubes, the steam being on the

outside of the tubes and the water passing through the tubes. The invention
consists of a method of breaking up the current of water as it passes through the
tubes by means of suitable deflectors which are suspended in the tubes.
invention is carried out in the following manner. In vessels which are used for
heating water by means of steam which steam surrounds a tube or tubes the steam
being confined by an outer casing, the casing having closed ends but through
which the tube or tubes pass, it is found that when the water to be heated is
passed through the tube or tubes, a certain portion of the water does not come in
contact with tube surface, the object of the invention being to prevent this, which
is done by placing in the tube or tubes (at short intervals) metal discs or other
obstructions which break up the current of water, thus bringing more particles of
water against the surface of the tube, and in order that our invention may be fully
understood & ascertained we append a drawing in which is shown a vertical section
of a feed water heater according to our invention.
O designates a cylindrical flanged casing the lower end of which is closed by a
cover a & the upper end by a cover a' each of these being connected to one of the
flanges of the cylinder in such manner as to form a steam tight joint. A metallic
plate 6 is inserted between the lower flange and the cover a and extends across the
whole of the end of the cylinder forming with the cover a chamber B. Similarly
a metallic plate extends across the whole of the upper end of the cylinder and
forms with the cover a chamber B' the plate ' forming a steam tight joint by
means of a packing ring between the edge of the plate & the cover a'. Each
of these plates b & b' has a number of holes bored in them into which any convenient
number of tubes A are inserted in such manner as to be steam tight and the
interiors of these tubes connect the chambers B and B in such manner that water
entering by the inlet D can flow up through the tubes and flow out through the
water outlet E. The tubes A are disposed sufficiently far apart to leave a space
between each in order that steam entering at the steam inlet G can surround the
.whole of these tubes & pass out at the steam outlet H.
Now in order to secure that the water shall in small particles or in thin films
come into actual and close contact with the interior surface of the steam heated
tubes, we insert a rod R in each of the tubes A and either form integrally with or
rigidly attach to it a number of discs K, or other shaped deflecting pieces of
metal so arranged as to break up the current of water & bring it in close contact
with the interiors of the steam tubes. These discs or their equivalents may be
arranged and fastened in the exterior of the tubes in any convenient manner
.suitable to ensure the the required effect.
We do not confine ourselves to any particular shape or construction of feed
water heater, but use any suitable kind permitting the insertion into the steam heated
tubes of discs or similar deflectors which cause the water to be forced into close
contact with the interior of the tubes.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is
1. Inserting discs or similar deflecting pieces of metal into the steam heated tubes of
feed water heaters for the purpose of breaking up the currents of water & causing
the same either in particles or thin films to come into close and intimate contact
with the interior of the steam heated tubes substantially as described & shewn.
2. In feed water heaters in which the water to be heated passes through steam
heated tubes, the method of breaking up the current of water in the manner shewn
'and described.
3. In combination with a feed water heater in which the water passes through
the inside of exterior steam-heated tubes, the discs or similar deflectors arranged
in such manner as to break up the currents of water substantially in the manner
and for the purpose described.

disc K, the latter being connected together either by the rod R or by other convenient.
means substantially as described.
