Improvements in or relating to the Settings and External Flues of
Steam Boilers.
JAMES BALDWIN, Engineer, Devonshire Brass Works, Keighley, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My improvement in or relating to the settings and external flues for steam
boilers I inake in the following manner:
On the top of the brickwork on each side and ends of the boilers, also in
between in cases where there is more than one boiler, I have a cast iron plate or
plates running the entire length of the boiler, and across the back ends. I have
covers or doors hinged, swung, sliding, or resting on these plates, made of cast
iron or other metals, of curved or other shapes, the outer ends resting against the
boiler, these covers being made of a shape suitable for carrying fire bricks, or
other bricks, or fire clay, and holding same in position. The covers or doors
may be made of any suitable width and length, and have handles or rings for
the purpose of opening or shutting when desired, to examine, clean or lift the
boiler or give daylight to the flues, as desired.
For filling up the space between the front and back walls, forming the ends of
the flues where the boiler above the centre line is exposed, I have wedge-shape
fire-bricks or other bricks, these bricks coming against an iron plate and having
rings so that they can be withdrawn when it is required to lift or raise the boiler.
The great advantage of constructing flues in this my improved manner is that
it renders easy the examination of a boiler as it can be lifted or raised from its
seat without disturbing the brickwork by opening the doors on the top of the
flues, drawing out the wedge shape blocks, and disconnecting the inlets and
outlets, the boiler is perfectly free.
Another great advantage possessed by this system is the facility given for
cleaning the flues, as by opening the top doors daylight is admitted and the plates
and flues can be thoroughly cleaned, and the former examined where the seating
comes into contact with the boiler.
In the drawing annexed hereto: Fig. 1 shows the front view of two boilers.
Fig. 2. shows the cover hinged. Fig. 3. without the hinge. B B in Fig. 1 shows
the two covers hinged CC attached to plate D and their outer ends EE resting
against the boilers A A. FF is means for fixing the firebricks or other bricks
or fire clay the covers for back of boiler being arranged in the same manner.
G G shows the wedge shape firebrick or other brick with ring H H for lifting
same. Fig. 2 shows the cover B hinged at C fixed to the plate 1) that rests on the
brickwork on each side of the boiler, and at the back of the boiler. Fig. 3 shows
the cover B without hinges but resting on the plate E that rests on the brickwork
on each side of the boiler and at the back of the boiler with ring G for lifting
same and showing the space F for holding fire-brick or other brick, or fire clay.

page_text: Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I claim is:-
1. The improved method of covering the flues of boilers for the purpose of
giving light and easy access to the flues, and enabling the boiler to be lifted or
raised without disturbing the brickwork, substantially as described and shown in
drawings.
2. The method of filling up the space from the two end walls to the radius of
the boiler by means of suitably shaped fire bricks or other bricks coming against
metal plates, substantially as described and shown in drawings.
