page_text: I JOHN WOODS of 524 Ashton Old Road Openshaw near Manchester in the
County of Lancaster, Foreman Smith, do hereby declare the nature of my invention
to be as follows:-
The object of this invention is improvement in that class of furnace used for
heating a series of bars or rods in the manufacture of bolts, nails, spikes, and other
similar article, and consists in dispensing with the usual fire clay blocks or lining.
hitherto employed, which have had a tendency, by the coke or other fuel used,
becoming clinkered to the tuyers and other parts to prove a hindrance to cleaning
out the furnace. This fireclay lining has also required frequent renewal.
In performing my invention I form each end of the furnace of a hollow (by
preference-cast iron) casing through which the tuyere pipes pass. These hollow
ends or casings are connected together by similar hollow casings but of a shallower
description which form the front and back of the furnace and which have openings
formed through them to admit the bars of metal required to be heated into the
furnace. Through these hollow casings I cause water to circulate and thus I am
enabled to construct a furnace which does not require to be lined with fireclay as
heretofore.

page_text: I JOHN WOODS of 524 Ashton Old Road, Openshaw, near Manchester in the
County of Lancaster, Foreman Smith, do hereby declare the nature of my inven-
tion 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 this invention is improvements in that class of furnace used for
heating a series of bars or rods in the manufacture of bolts nails spikes and other
similar articles and consists in dispensing with the usual fire clay blocks or lining
hitherto employed which have had a tendency by the coke or other fuel used
becoming clinkered to the tuyeres and other parts to prove a hindrance to cleaning
out the furnace. This fireclay lining has also required frequent renewal.
On the accompanying drawing Fig. 1. is a front view, Fig. 2. an end view and
Fig. 3. a plan of my improved Furnace. Fig. 4. is a transverse section of Fig. 1.
upon the line a-b. Fig. 5. is a front sectional view-one half upon the line a-b.
in Fig. 1. and the other half upon the line c-d. in Fig. 4. and Fig. 6. is a plan of
the base of the Furnace taken upon the line e-f. in Fig. 1.
In performing my invention I form each end of the furnace of a hollow (by
These
preference-cast iron) casing a. through which the tuyere pipes b. pass.
hollow ends or casings are connected together by similar hollow casings c. but of
a shallower description bolted together through the bolt holes c¹ (see Fig. 4.) which
form the front and back of the furnace and which have openings d. formed through
them to admit the bars of metal requiring to be heated into the furnace. Through
these hollow casings a. and c. I cause water to circulate and thus I am enabled to
construct a furnace which does not require to be lined with fireclay as heretofore.
Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is
The improved construction of furnace surrounded by water casings and whereby
fire clay lining or blocks are dispensed with substantially as and for the purposes
herein before described and illustrated on the accompanying drawing.
