DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley in the County of
York. "IMPROVEMENTS IN THE CONSTRUCTION OF MELTING FURNACES AND IN
APPARATUS FOR MAKING GAS FOR THE SAME' [the result partly of a communi-
cation from abroad made to him by Robert Good of Poughkeepsie New York and
partly of invention and discovery made by him]
This invention relates partly to an improvement in producers for making gas
for glass melting and other purposes and consists of the application of a blast pipe
to an ordinary Siemen's producer from a fan or blower which blast pipe operates
through a hole in the brickwork under the centre of the producer grate bars. By
means of this blast the gas is more rapidly produced and the more complete and
economical conversion of the fuel is attained.-Underneath the fire grates of the
producers one or more iron trays or dishes are fixed which are kept constantly
filled with water.
Iron doors are used for preventing the air forced in by the blast escaping except
up through the producer fire-A small steam pipe may be introduced into the blast
pipe a short distance from the producer where it is preferred to work with steam
as well as air,
The invention also applies to the side blocks of tanks or furnaces and according
to this I make each block hollow, having a cavity through of suitable size, Or the
sides of furnace may be constructed hollow by using thinner separate blocks and
forming a cavity between them:

page_text: At any suitable point in the sides, say at the end of one of the side blocks a
blast pipe is fitted into this cavity and cold air is blown in so that it passes along
the cavity all round the sides of furnace and a hole is formed in the block next
this end block (which receives the blast pipe) for allowing the egress of the air
which has thus been forced completely through the cavity in the blocks forming
the side of the tank or furnace.-The blocks forming the bottom of the tank or
furnace may also be provided with similar cavities and by suitably arranging the
holes the air may be made to pass underneath the entire bottom of tank or furnace
and if found necessary more than one receiving hole for the cold air may be
applied to the bottom or to the sides-A. cold air blast is also applied through a
hollow bridge between the melting and working out compartments of continuous
furnace. The blocks forming the bottom and sides may have their cavities
connected or they may be so that one supply of cold air will operate on the whole
-The air after it has been forced through the cavities in the sides or in the
bottom or in the bridge will be highly heated and in this state it may be utilized
in various ways as for instance being forced into the air regenerators under the
furnaces. It is also specially applicable to the following new arrangement for
what is technically called a gloury hole where the bottles are finished or made. A
blast pipe is arranged under the grate and the upper part of the gloury hole is
provided with holes for the introduction of the bottle neck.-At one side of the
upper part a door is fixed for feeding the fire and on the top a hood is fixed
connecting the same with the chimney which carries off the smoke. Where a blast
cannot be conveniently worked and especially in continuous tanks built on the T
shape described in Potter's Specification N° 2971-1882. There is arranged or
constructed across the part which forms the passages for the molten metal to pass
from the melting portion to the working out portions two large blocks of suitable
refractory material which are so formed that while one portion of them rests on
the sides of the passage the other portion goes below the surface of the metal for a
depth of say eighteen inches.-Between these two blocks a third is placed which is
dovetailed and so fixed between the two as to prevent its being lifted out of its
place by the pressure of the molten glass in the tank. The two first mentioned
blocks are kept in proper position by the weight of the arches forming top of tank
-The blocks are supported at underside in a suitable manner so as to give ample
space for the refined metal to pass through under the said blocks. The centre
block is made say six inches shallower than the other two and thus allow the
atmospheric air to act on the blocks which prevents them being rapidly worn
away.

DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley in the County of
York "IMPROVEMENTS IN THE CONSTRUCTION OF MELTING FURNACES AND IN
APPARATUS FOR MAKING GAS FOR THE SAME "
(the result partly of a com-
munication from abroad made to me by Robert Good of Poughkeepsie New York
and partly of invention and discovery made by me)
This invention relates partly to an improvement in producers for making gas
for glass melting and other purposes and consists of the application of a blast pipe
to an ordinary Siemens producer from a fan or blower which blast pipe operates
through a hole in the brickwork under the centre of the producer grate bars. By
means of this blast the gas is more rapidly produced and the more complete and
economical conversion of the fuel is attained. Underneath the fire grates of the
producers one or more iron trays or dishes are fixed which are kept constantly.
filled with water.
Iron doors are used for preventing the air forced in by the blast escaping except
up through the producer fire. A small steam pipe may be introduced into the
blast pipe a short distance from the producer where it is preferred to work with .
steam as well as air.
The invention also applies to the side blocks of tanks or furnaces and according
thereto I make each block hollow having a cavity through of any suitable size.
Or the sides of furnace may be constructed hollow by using thinner separate blocks
and forming a cavity between them.
At any suitable point in the sides say at the end of one of the side blocks a
blast pipe is fitted into this cavity and cold air is blown in so that it passes along
the cavity all round the sides of furnace and a hole is formed in the block next
this end block (which receives the blast pipe) for allowing the egress of the air
which has thus been forced completely through the cavity in the blocks forming
the side of the tank or furnace. The blocks forming the bottom of the tank or
furnace may also be provided with similar cavities and by suitably arranging the
holes the air may be made to pass underneath the entire bottom of tank or furnace
and if found necessary more than one receiving hole for the cold air may be
applied to the bottom or to the sides. A cold air blast is also applied through
a hollow bridge between the melting and working out compartments of continuous
furnace.
The blocks forming the bottom and sides may have their cavities connected or
they may be so that one supply of cold air will operate on the whole. The air
after it has been forced through the cavities in the sides or in the bottom or in
the bridge will be highly heated and in this state it may be utilized in various
ways as for instance being forced into the air regenerators under the furnaces.
It is also specially applicable to the following new arrangement for what is
technically called a glowry hole where the bottles are finished or made. A blast
pipe is arranged under the grate and the upper part of the glowry hole is provided
with holes for the introduction of the bottle neck. At one side of the upper part
a door is fixed for feeding the fire and on the top a hood is fixed connecting the
same with the chimney which carries off the smoke.
In order that my said invention may be most fully understood and readily
carried into effect I will proceed to describe the Drawings hereunto annexed.

page_text: making gas for glass melting and other purposes. Figure 4 is a longitudinal
section on the line X X of Figure 5 which is a transverse section on the line W W
of Figure 4 of a tank for melting furnace. Figure 6 is a longitudinal section on
the lino V V of Figure 7 which is a transverse section on the line UU of
Figure 6 of a modification of the above. Figure 8 is a transverse section of a
bridge between the melting and working out compartments of a continuous
furnace.
Figure 9 is a front elevation Figure 10 a side elevation and Figure 11 is a
portion of a sectional elevation of what is technically called a glowry hole.
Referring to Figures 1. 2. and 3 A is the blast pipe fixed or placed in the
brick work B and having branches a. a. which extend in an oblique direction to
the sides of the brickwork B the grates C. C. are above the branches a. a. of
the blast pipe A so that the blast blows fairly under the whole surface of the
grates C. C. A valve b is fitted in the blast pipe A so as to regulate the amount
of blast.
This blast pipe A is connected with a fan or blower of any suitable kind by
means of which the air is driven through the pipe. The trays or dishes DD
extend the whole depth of the grates C. C. and are kept constantly filled with
water by means of the water pipes E E which have valves e. e. for regulating the
supply.
The iron doors H H are suspended by the hinges h. h. h. h. the bottom part of
the doors H H enter the trays or dishes D. D. The iron doors HH close up the
space under the grates C. C. and thus prevent the air forced in by the blast
escaping except up through the producer fire. A small steam pipe d may be
introduced into the blast pipe A where it is preferred to work with steam as
well as air.
The before described arrangement is not only applicable to Siemens producers
but to any other kinds of producer which has a hollow underneath the grate the
same as Siemens bas.
Referring to Figures 4 and 5 the side blocks I. I. of the tank or furnace K have
cavities . . these blocks I I may either be in halves as shown or the cavity may
be made through the block and the block I will be all in one piece. The bottom
blocks L of the furnace K are also made with cavities Z. Z. these blocks L L may
either be in halves as shown with the cavities l. 1. between them or may be all in
one piece with the cavities l. l. made through them.
Or the sides and bottom of the furnace K may be constructed as shown at
Figures 6 and 7 in which case the sides of the furnace K are formed by means of
two thinner blocks I. I. having the cavity between them. The bottom of the
furnace K is also formed by means of the two thinner blocks L L having the
cavity between them the upper blocks may be kept a distance from the lower by
means of the fire brick supports or pillars k. k.
A blast pipe M is fitted into the side block I. The cold blast driven by a fan or
other suitable blower enters through this pipe M into the cavities i. i. A discharge
pipe N is fitted into the bottom block L and thus allows the egress of the air
which has been forced through the cavities i. i. and l. l. The Cavities i. i. are
connected to the cavities l. l. by means of the passages M M
Referring to Figure 80 is the hollow bridge between the melting compart-
ment P and the working out compartment p. The bridge O has a cavity o formed
in it through which a cold blast is made to travel by connecting the bridge with
the blast pipe M in manner before described. The cavity o may be to any suitable
size. The cavities i. i. and . L. may be connected as shown at Figures 4. 5. 6
and 7 so that one supply of cold air will operate on the whole or in other words
one supply of cold air may be made to travel all along the cavities i. i. and l. l.
having an ingress by means of the blast pipe M and an egress by means of the
discharge pipe N. Or the cavities i. i. and l. 1. may be disconnected and have
separate supplies of cold air in which case the number of blast pipes M and N
would have to be increased,

page_text: Referring to Figures 9. 10 and 11 the discharge pipe N is placed under the
grate n of the glowry hole Q.
The air after it has travelled along the cavities i. i. and Z. Z. of Figures 4 and 5
has become highly heated and may be utilized not only in the way as shown in
Figures 9. 10 and 11 but the pipe N may be connected to the air regenerators
under the furnaces the hot air being thus forced therein (as will be well
understood).
Referring again to the Figures 9. 10 and 11 the hot air enters under the grate n
of the glowry hole Q by means of the pipe N. The glowry hole Q has holes q. q. q.
for the introduction of the bottle necks. The door is for feeding the fire and the
door S is for the removal of the ashes. The hood is fixed so as to connect the
glowry hole Q with the chimney u which carries off the smoke.
Having thus described the nature of my invention and in what manner the same
is to be performed I would have it understood that I do not claim the application
per se of a blast pipe from a fan or blower to producers neither do I claim the
use per se of a hollow bridge as described at Figure 8 but I do claim :-
First The special arrangement of blast pipes under a gas producer substantially
as shown and described in connection with Figures 1. 2 and 3 of accompanying
drawings.
-*
Second-The application of a supply of cold air from one or more blast pipes
(actuated by a fan or other suitable blower) to the sides or bottoms or hollow
bridges of melting furnaces substantially as shown and described with reference to
Figures 4. 5. 6. 7 and 8 of accompanying drawings.
Third The adaptation and use of cavity blocks for the sides and bottoms of
melting furnaces (each block consisting of one or more pieces) and the supplying
of cold air to such cavities substantially as shown and described with reference to
Figures 4. 5. 6 and 7 of accompanying Drawings.
Fourth-The special arrangement for utilizing the hot air in the glowry hole as
shown and described in connection with Figures 9. 10 and 11.
In witness whereof I the said Dan Rylands have hereunto set my hand and
seal this Twentythird day of April in the year of our Lord One thousand eight
hundred and eighty four.
