PROVISIONAL SPECIFICATION.
An Improvement in or relating to Furnace Bars or Fuel Supports.
I, RICHARD SIMON, of Zulla Road, Nottingham, Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an improvement in furnace bars or fuel supports.
According to present practice, furnace bars are composed of comparatively long
castings with side cheeks at intervals as distancing webs and so regulate or
determine the amount of air space between each pair.
As a rule, furnace bars are subject to great heat and become burnt which causes
them to cockle being thereby rendered useless and fresh bars must be employed to
replace those thus destroyed.
Now the object of my invention is to prepare and fix what may be termed
foundation bars, hollow or solid and of any desired shape. These are fixed bars
on which for the purpose of my invention, arrange any number of cast blocks
to serve as fuel bearing bars and occupy a position and purpose like ordinary
bars.
The blocks may be of any desired shape to sit on the fixed or foundation bars,
or to straddle them each one having side webs as distancing pieces for forming the
air spaces between the blocks which can be fitted or be slid along on the foundation
bars in close contact, having end studs to regulate their distance apart on each
foundation.
and
ог
By this invention, blocks as they become burnt can be shifted to other parts of a
furnace less liable to intense heat, so that each and all the blocks of a bar can be
acted upon before renewal. Thus the life of a furnace bar is lengthened, the blocks
being readily put in and taken out of the furnace without the necessity as at present
of removing the front cross plate, the back cross plate, or the door plate because
the foundation bars are not affected by heat they being covered and protected by
the blocks upon them.

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:-

A is a tube of any suitable section on which slide freely cast iron blocks B
having guiding or steadying projections C. The upper surface of the blocks B may
be chilled.
The tubes A are of any shape in cross section and I prefer to reduce their ends
so that said ends can be enclosed in socket pieces D, D, to rest upon the back
bearer E and the front plate F respectively as seen at Figure 4.
Furnace bars made in this manner have the following advantages:-
Blocks as they become burnt can be shifted to other parts of a furnace less
liable to intense heat, so that each and all the blocks of a bar can be acted upon
before renewal. Thus the life of a furnace bar is lengthened the blocks being
readily put in and taken out of the furnace without the necessity as at present of
removing the front cross plate, the back cross plate, or the door plate because the
foundation bars are not affected by heat they being covered and protected by the
blocks upon them.
They are lighter and consequently cheaper than others.
They allow more air to pass to the coals and consequently ensure a more complete
combustion.
The air passing through the tubes tends to keep them, and by conduction the
blocks, cool, and mixing with the products of combustion on the bridge, consumes
the smoke.
My system admits of the detachment and replacing of any burnt out or defective
portion with little trouble and without having to sacrifice the whole bar.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I do not limit myself to
precisely the form shown but I declare that what I claim is :-
The combination of a loose and easy fitting block on a tube or rod as and for
the purpose described.
