We ARTHUR Lowcock of The Economiser Works Shrewsbury in the County
of Shropshire Engineer and THOMAS SYKES of 25 Milton Street Stockport Road
Manchester in the County of Lancaster Engineer do hereby declare the nature of
our invention for IMPROVEMENTS IN THE APPARATUS KNOWN AS FUEL ECONOMISERS
WHICH APPARATUS MAY BE USED FOR HEATING WATER OR GENERATING STEAM
to be as follows:-
Our invention relates to the apparatus known as fuel economisers and consists
in arrangements by which we simplify the construction and increase the efficiency
of such apparatus.
In accomplishing the above object we employ metal pipes or tubes formed by
drawing welding brazing or casting or by any other suitable means and place such
pipes or tubes in groups of two or more pipes or tubes which groups of two or
more pipes or tubes we connect at their ends to boxes or chambers the interiors of
which boxes or chambers are in communication with the interiors of the above
mentioned pipes or tubes. One or both of the boxes or chambers above named is
or are provided with a lid or cover or lids or covers secured thereto by bolts or
other suitable means, by which lid or cover or lids or covers access may be obtained
to the interior of the before mentioned pipes or tubes for examination cleansing or
for repairs. In some cases we provide each of the boxes or chambers above
mentioned with two or more lids or covers.
We secure the pipes or tubes above mentioned to the boxes or chambers
previously mentioned by expanding swaging cementing or by forming the ends of
the aforesaid pipes conical and by forming suitable conical sockets upon the boxes
or chambers previously referred to or in any other convenient and suitable manner.
The water to be heated or converted into steam is supplied to the box or
chamber before referred to situate at one end of the pipes or tubes before referred
to and after being heated passes to the box or chamber situate at the end opposite
to that above mentioned, of the pipes or tubes previously referred to.

Improvements in the Apparatus known as Fuel Economisers,
which Apparatus may be Used for Heating Water
Generating Steam.
or
We ARTHUR LOWCOCK of The Economiser Works Shrewsbury in the County
of Shropshire Engineer and THOMAS SYKES of 25 Milton Street Stockport Road
Manchester in the County of Lancaster Engineer do hereby declare the nature of
our invention for IMPROVEMENTS IN THE APPARATUS KNOWN AS FUEL ECONOMISERS
WHICH APPARATUS MAY BE USED FOR HEATING WATER OR GENERATING STEAM
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Our invention relates to the apparatus known as fuel economisers and consists
in arrangements by which we simplify the construction and increase the efficiency
of such apparatus.
In accomplishing the above object we employ metal pipes or tubes formed by
drawing welding brazing or casting or by any other suitable means and we place
such pipes or tubes in groups of two or more pipes or tubes which groups of two
or more pipes or tubes we connect at their ends to boxes or chambers the interiors
of which boxes or chambers are in communication with the interiors of the above
mentioned pipes or tubes.
a. are the
In order that our invention may be thoroughly understood and readily carried
into effect we will now proceed to describe the same by reference to the drawing
hereunto annexed in which drawing Fig. 1 is a side elevation partly in section and
Fig. 2 is an end view of a fuel economiser constructed according to our invention
and Fig. 3. is a plan of the lower portion of the said fuel economiser.
bottom boxes or chambers and b are the top boxes or chambers-We connect the
bottom boxes or chambers a. and the top boxes or chambers b. by pipes or tubes c.
which pipes or tubes c. we arrange in groups which groups are shown at A. Each
Each of
of the groups A of pipes or tubes c. is composed of three pipes or tubes c.
the pipes or tubes c. is secured to the bottom box or chamber a. and top box or
chamber b at its lower and upper ends by passing into sockets d. e. formed upon the
bottom boxes or chambers a. and top boxes or chambers b. respectively, and the
pipes or tubes c. are secured in the sockets d. e. formed upon the bottom boxes or
chambers a and top boxes or chambers b respectively by being expanded by swaging
cementing or by the ends of such pipes or tubes c. and the sockets into which they
pass being formed conical or in any other convenient and suitable manner-In order
to allow access to the interiors of the top boxes or chambers b. and of the pipes or
tubes c. to be obtained for the purpose of cleaning repair or other purpose we provide
each of the top boxes or chambers 6 with the usual covers f. each of which covers f.
is secured by means of a nut g. to the top box or chamber b to which it is applied―
The pipes care situate between and supported by the walls h. The waste products
of combustion from the steam boiler or other furnace to which the fuel economiser

page_text: above described is applied pass between the pipes c in the direction indicated by the
arrow B and coming in contact with the said pipes or tubes c. beat the water
contained in or passing through such pipes or tubes o. By our invention we are
enabled to employ pipes or tubes c. formed of metal which readily conducts heat such
as for instance brass or copper so that the water in the interiors of the pipes or tubes o
becomes more readily heated than in the pipes or tubes hitherto in use in fuel
economisers. We place each of the groups A of pipes or tubes c opposite one of the
spaces between two of the groups A of pipes or tubes c of the row next in advance
as is usually done with the pipes ordinarily employed in fuel economisers-The
water to be heated is supplied as usual to the bottom boxes or chambers a and
passes thence through the vertical pipes or tubes c into the top boxes or chambers b
and from the top boxes or chambers b to the place where it is to be used.
In some cases we form each of the top boxes or chambers as shown in Figs. 4
and 5 in which Figures Fig. 4 is a partial side elevation and Fig. 5 a cross section
of a top box or chamber constructed according to this modification of our invention.
We form the top box or chamber; with an opening at its top, which opening we
close by means of a cover or lid ke which cover or lid k is secured to the top box or
chamber by means of bolts and nuts m. which bolts pass through holes formed
through the flange 71 formed upon the top box or chamber j. and through the cover
or lid k. The cover or lid k extends throughout the entire length of the top box
or chamber j. In some cases we divide the cover or lid k into two or more portions
as may be found desirable.
We have hitherto referred to the groups A of pipes or tubes c as being composed
each of three pipes or tubes c but we would have it understood that each of the
groups A of pipes or tubes c may be composed of two or more pipes or tubes as
may be desired.
In some cases we provide the bottom boxes or chambers a with a cover or lid or
covers or lids similar to those above described as being applied to the top boxes or
chambers j. By means of the covers or lids above referred to access to the
interiors of the top boxes or chambers j and of the pipes or tubes c and of the
bottom boxes or chambers a for the purpose of cleaning repair or other purpose
may be obtained.
Although we have shown in the drawing hereunto annexed the pipes or tubes c
as being vertical we would have it understood that such pipes or tubes c may if it
be so desired be placed in an inclined position.
Our invention by enabling us to employ in fuel economisers pipes or tubes c of
brass copper or other metal which readily conducts heat, enables us to employ in
fuel economisers pipes or tubes c having a smooth exterior or interior surface so
that such pipes or tubes are less liable to become coated on the outside with soot
and on the inside with matters deposited from the water contained in or passing
through such pipes or tubes than the cast iron pipes or tubes ordinarily employed
in fuel economisers. Any soot deposited upon the outsides of the pipes or tubes c
may be removed by means of a jet of steam and the scrapers ordinarily employed
in conjunction with fuel economisers may be dispensed with.
Having now 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. In such of the apparatus known as fuel economisers as have the pipes or tubes
employed therein arranged in groups of two or more pipes or tubes connecting
such pipes or tubes directly with the bottom boxes or chambers and top boxes or
chambers employed in such fuel economisers.
2. Providing each of the top boxes or chambers of the apparatus known as fuel
economisers with a lid or cover constructed and arranged substantially as and for
the purposes described and shown in reference to and in and by Figs. 4 and 5 of
the drawing hereunto annexed.
