PROVISIONAL SPECIFICATION.
Improvements in or relating to Fuel Economisers.
We, ARTHUR ROBERTS and HARRY ROBERTS, trading under the style or firm
of Roberts Brothers of Hollingworth near Manchester in the County of Lancaster,
Fuel Economiser Manufacturers, do hereby declare the nature of our said invention
to be as follows:-
This invention refers to improvements in or relating to fuel economisers and
consists of a new form or construction of top and bottom boxes so as to make
them stronger to resist the high pressures now required; also in means for more
effectually blowing out mud and the like, and giving easier access for inspection
and repairs. This we carry into effect by constructing the top and bottom boxes
on the angular principle provided with bosses of equal length to receive the
vertical economiser pipes of one uniform length. The said boxes are placed on
such an angle that it will be impossible for dirt, scum or mud to collect, the same
being delivered to the mud drum and blown out more effectually than hitherto.
The economiser pipes are arranged in groups or tiers with several rows of equal
number in the middle, each side being of unequal numbers to form a space or
passage to allow of the middle parts of the said groups or tiers being inspected
and repaired without taking out or disturbing any of the pipes. By thus disposing
the said pipes in a zig-zag forin the impinging action is increased and efficiency
effected, and which also allows of scrapers being placed on the middle pipes without
the removal of the said pipes.

Improvements in or relating to Fuel Economisers.
We, ARTHUR ROBERTS and HARRY ROBERTS, trading under the style or firm
of Roberts Brothers of Hollingworth near Manchester in the County of Lancaster,
Fuel Economiser Manufacturers, do hereby declare the nature of our said invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-

DESCRIPTION OF DRAWINGS.
Fig. 1 is a plan of our improvements in fuel economisers, and Fig. 2 a sectional
elevation through line A B in Fig. 1.
C are the economiser pipes-; D the scrapers; E top box; G bottom box ; H mud
drum; I soot chamber, and J brickwork enclosing the same.
The top box E and bottom box G are constructed and fixed on the angle and
are provided with the bosses K of equal length and in line with the vertical
pipes C, by which the latter are of one uniform length. The boxes E and G are
placed at such an angle that it is impossible for dirt, scum, or mud to collect, the
same being delivered to the mud drum H and blown out more effectually than
hitherto. The economiser pipes C are arranged in groups or tiers with several
rows of equal number in the middle, on each side of which are placed groups or
tiers of an unequal number of pipes C to form the spaces or passages M to
allow of the middle parts of the said groups or tiers being inspected and repaired
without taking out or disturbing any of the economiser pipes C. By thus
disposing the economiser pipes C in the zig-zag form shown in the drawings in
Fig. 1 the impinging action is increased and efficiency effected. The spaces or
passages M also allow of the scrapers D being placed on the middle pipes without
removing the said pipes as hitherto. By placing the pipes C in a zig-zag form
more heat is radiated, thorough inspection facilitated, repairs executed in considerablý
less time than under the old or present system, and the taking down of brickwork
for repairs is entirely dispensed with. This invention also allows of each box, pipe,
scraper bar, scraper, rod, and chain being examined at will.
Having now particularly described and ascertained the nature of our said inveu-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In combination with economiser pipes the use of the angular top and bottom
boxes with bosses of equal length in line with the vertical economiser pipes to
allow of the latter being of uniform length, substantially as described and shown in
the annexed drawings for the purpose specified.
2. In combination with economisers the disposing of the pipes to form the spaces
or passages M for the purpose specified, substantially as described and shown in
the drawings.
