PROVISIONAL SPECIFICATION.
Improvements in the Construction of Domestic Washing Boilers.
I, JOHN ATKINSON of 23 Minnie Street, Daubhill, Bolton in the County of
Lancaster, Brick Maker, do hereby declare the nature of my said invention to be
as follows:
This invention relates to improvements in the construction of domestic washing
boilers and is designed to increase the efficiency of the same with a minimum
of coal or fire. The outer surface of the washing boiler is encircled with a chamber
or cavity, through which flame, heat, and smoke pass in their passage from
the fire to the chimney. To ensure flame, heat, and smoke passing through the
aforesaid chamber or cavity the brickwork seating is provided with a midfeather to
direct the same.

COMPLETE SPECIFICATION.
Improvements in the Construction of Domestic Washing Boilers.
I, JOHN ATKINSON of 23 Minnie Street, Daubhill, Bolton in the County of
Lancashire Brickmaker 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 :-
The object of my invention is to provide a means whereby domestic washing
boilers may be more readily and economically fixed or built into position than
heretofore.
To accomplish this I form the circular flue which passes round the sides of the
boiler of metal, either casting it attached to and as part of the boiler, or separately
in the form of a hollow ring of suitable shape, which can be built into the brickwork
and form part of the boiler seating.
This circular flue is provided with a suitable internal partition of metal at one
part of its circumference, on one side of which is left an opening for the hot gases
from the fire to enter, and upon the other a suitable opening with projecting flanges
to conduct the smoke into the chimney after it has passed round the boiler.
In order that the foregoing may be better understood, 1 send herewith a sheet of
drawings in which;
Fig. 1 shows a cross section of a boiler fitted with my improved flue and
Fig. 2 a perspective view of my improved flue as cast separately from the
boiler.
Referring to Fig. 1, a indicates the ordinary grate from which the flames enter
the flue 6 by opening c and after passing round the boiler d as shown by broken
lines e pass out into the chimney by opening 9.
The use of my improved flue allows the boiler to be plainly built into the
brickwork h.
The same parts are indicated in Fig. 2 by the same reference letters, the casting
it is to be noted is left open on its inner face so that the flames may play upon the
naked hailan

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A metal flue, for encircling washing boilers, substantially as described and shown
hereinbefore and in the accompanying drawings, for the purpose set forth.
Dated this 9th day of February 1893.
