PROVISIONAL SPECIFICATION.
Improvements in and connected with Boiler Seating Blocks and
Flue Covers.
I EDWARD JOSEPH CURTIN of 6 St. Ronan's Avenue, Redland, Bristol,
Managing Engineer do hereby declare the nature of this invention to be as
follows:
My invention relates to certain improvements in the form or shape of seating
blocks and flue covers used for the purpose of seating steam boilers and covering
the tops of their side and back flues.
These seating blocks are at present usually made of fire clay with plain surfaces
for the boiler to rest on, and the flue covers are also usually made of fire clay with
plain surfaces for resting against the boiler.
According to my present invention I groove or corrugate the surfaces of the
seating blocks and flue covers where they touch the boiler, with grooves or corru-
gations of any size or shape for the purpose of reducing their surfaces and enabling
a more perfect examination of the skin of the boiler to be made when the same is
under inspection.
When the boiler is in work these grooves or corrugations can be stopped with
asbestos fireclay or any other material or pieces of these or any other material
shaped to suit the grooves or corrugations may be used and withdrawn and replaced
as may be desired.
These boiler blocks and flue covers may also be corrugated or grooved all over
or on any or either side and may be made of fire clay asbestos or any other material
or of iron or steel or any other metal or of a combination of any metals or
materials whatever and of any design or shape and may be used for other purposes
than the setting of steam boilers.
Dated this Eleventh day of January 1895.
COMPLETE SPECIFICATION.
Improvements in and connected with Boiler Seating Blocks and
Flue Covers.
I, EDWARD JOSEPH CURTIN, of 6, Saint Ronan's Avenue, Redland, Bristol,
Managing Engineer, 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 consists in improvements in seating blocks and flue covers of
boilers.
Hitherto the practice has been to make boiler seating blocks and flue covers even
or plain on the faces for contact with the boiler.
According to this invention the faces are fluted or grooved. Only the ridges
thus formed are in contact with the boiler, external examination of which along
the line of seating blocks and along the line of flue cover faces is facilitated.

page_text: To prevent escape of heat through the grooves they may, if desired, be blocked
by a piece of fire-clay or other suitable material which may be at any time dislodged
without injury to the blocks and flue covers, which remain in place. Or, suitably
shaped plugs of fire-clay, or other suitable material, may be used to close the
grooves; such plugs being readily withdrawn and replaced.
Referring to the accompanying sheet of illustrative drawings, Fig. 1 represents,
in end view, a boiler seating block a made in accordance with this invention.
Fig. 2 is a front view. The face a¹ is fluted or grooved, as seen more particularly
at Fig. 2.
At Fig. 3 is illustrated, in end view, and at Fig. 4 in front view, a boiler flue
cover having the face b¹ fluted or grooved in a similar manner to the seating
blocks. At Fig. 5 is represented, in end view, and at Fig. 6 in side view, a steam
boiler c set on seating blocks a made in accordance with this invention. The flue
covers b, not seen in Fig. 6, are also made in accordance with this invention.
The boiler c bears against the ridges only of the blocks and flue covers. Hence,
inspection of the boiler along the line of the seating block faces and the flue cover
faces is facilitated.
The ridged and grooved faces of the seating blocks and flue covers may, instead
of being formed in one with the blocks and covers, be separately made and suitably
fitted thereto so as to be removable at will.
The faces may be made in iron, steel or other suitable metal and be fitted to
bodies of fire-clay or the like. Or the blocks and covers may be made wholly of
such metal.
To facilitate access to the faces of the flue covers 6 the blocks d of the boiler
setting which lie next the boiler are removable and are made with a rib d¹ for the
purpose of taking them out and replacing them. One such block is shown at
Fig. 5 as removed at the right-hand side of the boiler and deposited on the setting.
The ridges d' of the blocks d form a good abutment for the usual external
composition covering the boiler.
Seating blocks, flue covers and the like made in accordance with this invention
are applicable to other boilers than steam boilers. They are applicable to brewers'
coppers and other kinds of boilers or kindred appliances.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
Seating blocks and flue covers, of fire-clay or other suitable material, or of iron,
steel or other suitable metal, for steam and other boilers and heating vessels, fluted
or grooved on the faces lying next the boilers, or other vessels, the fluted or
grooved parts being either removable or fixed to the bodies of the blocks or covers,
substantially as hereinabove described.
