for Use in the Manufacture of Glass.
WE DAN RYLANDS of Hope Glass Works, Stairfoot, near Barnsley, in the County
of York, Glass Bottle Manufacturer, and RICHARD POTTER of Camden Terrace,
Stairfoot aforesaid, Furnace Builder, do hereby declare the nature of this invention to
be as follows:-
This Invention relates to Furnaces constructed according to Potter's Patent
No. 2971 of 1882, and consists in several improvements thereto which we herein
provisionally describe and illustrate by means of the accompanying drawings and
description.
Fig. 1 is a sectional plan of our improved Furnace.
Fig. 2 is a sectional elevation of part of said Furnace taken on line a a of Fig. 1
and Fig. 3 is a perspective view of the improved fireclay blocks which we use in the
construction of said Furnace.
;
The improvements in the arrangement of the Furnace consist in :-First, making
the melting portion R considerably longer than that described in Potter's Patent
No. 2971 of 1882, by which means the molten glass has a longer distance to travel
before it reaches the working-out departments A A and thereby becoming more
refined and of a better quality Second, in so arranging the spaces VV wider that
air can be applied thereto, thereby lengthening the life of the sides of the Furnace
which are there situated; third, in constructing the sides S, ends E, and stop pieces Bof
firebrick blocks which are perforated or inanufactured with any number of suitably
shaped holes d running horizontally through them as shown at Figs. 2 and 3, the
said stop piece B being preferrably formed with as many horizontal holes as practicable
though the said stop pieces may be solid; fourth, in applying suitable cold blast or air
to the interior of the perforations or horizontal passages or holes d so that the said
blocks are kept cooler by which means they do not burn or wear away as soon as the
class of blocks in use hitherto.
The blast or cold air is preferrably forced in at f and f¹ and passes through the

page_text: locks which constitute the side S and ends E of Furnace and then escapes at h and
Cold air is also blown through the whole of the perforations of the stop piece B
f
'rom either end thereof.
The escaping hot air may be conducted to the air regenerators where so preferred,
or may be employed in any other economical manner; and also where so preferred
the blast may pass through the blocks which constitute the working-out ends E' E' of
Furnace, in which case the cold air enters at f¹, and instead of escaping at h¹ passes
through the blocks which form the ends E E¹ and then escapes at h.
The Furnace may either be fed through the crown of the melting portion R, or
over suitable holes formed on the sides S or through a suitable feeding hole formed
at the end E of the melting compartiment, or, by means of a shoot connected to a
hole formed through the top corner of the said end E.
Various modifications of these arrangements are possible which we shall show in
our final specification.

COMPLETE SPECIFICATION.
Improvements in Regenerative Gas Furnaces, Specially Applicable
for Use in the Manufacture of Glass.
We, DAN RYLANDS, of Hope Glass Works, Stairfoot, near Barnsley, in the County
of York, Glass Bottle Manufacturer, and RICHARD POTTER, of Camden Terrace,
Stairfoot. aforesaid, Furnace Builder, 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:-
Our present invention relates to Furnaces constructed according to Potter's Patent
No. 2971 of A.D. 1882, and consists in several improvements thereto, which we
illustrate by means of drawings left with our Provisional Specification, and also with
drawings hereunto attached, the following being a description of both sets of
drawings.
In the drawings left with our Provisional Specification, Fig. 1 is a sectional plan of
our improved furnace built after the style of Potter's Patent No. 2971 of A.D. 1882,
but having several improvements added thereto. Fig. 2 is a sectional elevation of
portion of said Furnace taken on line a a of Fig. 1, and Fig. 3 is a perspective view
of our improved fire-clay blocks or blocks of other refractory material, which we use
in the construction of our Furnace.
In the drawings hereto attached, Fig. 4 is a longitudinal sectional elevation of

page_text: portion of melting department R commencing at the end E. Fig. 5 is a cross section
of portion of said melting department R. Fig. 6 is a longitudinal sectional elevation
of portion of melting department R and Fig. 7 is the same.
Referring to Figs. 1, 2, and 3, the melting portion R of Furnace is constructed
considerably longer than that described in Potter's Patent No. 2971 of 1882. By this
means (the Furnace being fed with batch near the end E) the molton glass has a longer
distance to travel or flow before it arrives at the working-out departments A A. It
thereby becomes more refined and of a better quality for manufacturing into bottles or
other articles.
Our improvements also lie in arranging the spaces V V, which come between the
melting department and working-out departments of the Furnace, considerably
wider so that atmospheric air can be applied thereto, by which means the sides of the
Furnace there situated last much longer than hitherto.
Our present improvements also consist in constructing the sides S, ends E, and
stop-pieces B, of fire-brick or other refractory blocks, which are perforated with any
number of suitably constructed holes d running horizontally through them, the stop-
pieces B being preferably formed with as many holes as practicable, though they may
in some cases be made solid.
We apply suitable cold blast or air to the interior of the before-described perforations
or horizontal passages or holes d, by which means the blocks which constitute the sides
and ends of our improved Furnace are kept cooler so that they do not burn or wear
away as easily and as soon as the class of blocks hitherto in use. The hereinbefore
described cold air or cold blast is preferrably forced in at fand f, and blows through
the perforations d formed in the blocks which constitute the sides S and end E, and
then escapes or blows out at g, h, and h². Cold air may also be blown through all the
perforations d formed in the stop-pieces B. The block B extends across the passage
which divides the working out department A from the melting department R as shown
at Fig. 2 of the drawings left with the Provisional Specification. The said cold air
may be blown into the perforations d of block B either from the end thereof which
rests on the side E of furnace, or the end which rests on the side S of furnace. When
the cold air is blown in from the side E, a suitable number of pipes conducting the
cold air up to each perforation may be employed, or a hood may be placed over all the
said perforations d and the cold air conveyed thereto by means of one pipe. When
the cold air is thus blown into the perforations d from the end resting on the side E,
the cold air is conducted from said perforations d formed in block B into the perfora-
tions & formed on the side S, after which escapes at and h; in this case the air
entrances are dispensed with. Instead of cold air being blown into the ends of block B
from the side E as described it may where preferred be blown through in the
reverse direction, that is from the end which rests on the side S and looks towards the
space V in this case the air can be either conducted downwards into the perforations d
formed in the side E, and permitted to escape at ', in which case the air ingress f¹
may be dispensed with, or the cold air may be merely blown straight through the
perforations d formed in block B and from either side thereof, and the said air after
passing therethrough may be conducted to the regenerators or conveyed away to he
utilised for any other purpose as will be well understood.
The escaping air or blast which has become heated during its journey through the
sides S and E may also be conducted to the air regenerators as will be well understood,
or may be employed in any other economical manner. Where preferred, the cold air
or blast may be arranged to pass through the blocks which constitute the working-out
ends EE of Furnace, in which case the cold air or blast preferrably enters at fand
instead of being permitted to escape at is made to pass through the blocks which
constitute the said ends E' E', and then may escape at h. We would have it well
understood that the cold air or blast may be arranged to enter the blocks at any
suitable part or parts of the Furnace, and also arranged to escape at any suitable place
or places.
Referring to the drawings hereunto attached, the Furnace may be fed through the
crown R¹ (Fig. 4), or through suitable holes S¹ formed in the sides S (Fig. 5), or

page_text: through a suitable feeding hole E2 formed at the end E of melting department R
(Fig 6), or by means of a shoot Parranged at an angle and connected to a hole E²
formed through the top corner of said end E (Fig. 7).
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what we
claim is :-
1. The construction of Furnaces for melting glass with lengthened melting
portions R and with wide spaces Y substantially as described and illustrated at Fig. 1 of
the drawings left with the Provisional Specifications.
2. In the construction of Furnaces for melting glass arranged with a melting
department R and working-out departments A A, the use of perforated blocks as
stop-pieces substantially as described.
3. The application of cold air or blast to the stop-pieces substantially as described.
4. In connection with Furnaces constructed after the manner herein described, the
adaptation of feeding holes either on the top or at the ends, or corners or sides,
substantially as described and illustrated at Figs. 4 to 7 of the accompanying
drawings.
