PROVISIONAL SPECIFICATION.
Improvements in and relating to Gas Glory-hole Furnaces.
JOSEPH SILVERS WILLIAMS, Glass Manufacturer of Brierley Hill, Staffordshire,
and JOHN NORTHWOOD, Glass Manufacturer of Brierley Hill, Staffordshire, do
hereby declare the nature of this invention to be as follows:-
This invention relates to the heating of small furnaces technically known as
glory-holes for reheating glass articles in the course of manufacture, and consists of
supplying the atmospheric air to the mixing tube of a Bunsen burner with a gauze
top, from the exterior of the glass-house, by means of a pipe connected to the said
burner; the air being so rarified in glass-house as to cause a rush of cold air through
the pipe to burner this mixing with the gas and creating a perfect combustion, with
intense heat, when ignited, without the aid of a fan or blower.
The furnace or glory-hole can be fixed over the burner or in any other position
most convenient to the workman.
Dated this 19th day of September 1890.

COMPLETE SPECIFICATION.
Improvements in and relating to Gas Glory-hole Furnaces.
JOSEPH SILVERS WILLIAMS Glass Manufacturer of Brierley Hill Staffordshire
and JOHN NORTHWOOD Glass Manufacturer of Brierley Hill Staffordshire 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 relates to small furnaces used in glasshouses and technically
known as glory holes for re-heating glass articles in course of manufacture.
It consists of supplying atmospheric air by means of a pipe A from exterior of
glasshouse to the mixing tube of a burner B similar in construction to a Bunsen
burner, preferably with a metal gauze top of fine mesh or gauge. The air being so
rarified in the stack or chimney by the heat from the large melting furnace of
glasshouse thereby causing a rush of cold air from outside through the aforesaid
pipe to the burner, which is regulated by a valve D in an adjustable quantity to
the gas supply C required, or the current of air can be supplied by means of a fan,
blower, or other machine to the aforesaid pipe and regulated in the same manner.
The furnace E is made of clay of a refractory nature and of any suitable shape and
size with hole in bottom F to fit over the top of previously described burner, also
a hole H H in the top of furnace to take off waste heat or to serve by connection
with a pipe to the stack of large furnace, or to form a stack of its own if extra
draught is required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The use of an atmospheric burner combined with a suitable furnace for re-heating
glass articles in the course of manufacture, the air being supplied from the exterior
of the glasshouse, which is caused by the rarification of the air in glasshouse stack
from the heat of melting the glass in large furnace to be drawn into burner or with

page_text: air under pressure, capable of being regulated by a valve in an adjustable quantity
to the gas supplied, thus producing a highly oxidising flame within the furnace or
glory hole.
