Improvements in Glowry-holes for Fire-polishing Pressed or other
Glass Articles.
We HENRY HARLEY PITT, of Low Fell Gateshead-on-Tyne, in the County
of Durham, Engineer, and SoWERBY'S ELLISON GLASS WORKS LIMITED,
of Gateshead-on-Tyne, aforesaid Glass Manufacturers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to an improved glowry-hole for fire-polishing pressed or
other glass articles, the object being to so arrange or construct the same that a
number of glass articles may be expeditiously and efficiently fire-polished in the
least possible area or surface thereby economising the heat necessary for the said
fire-polishing; to attain which we arrange a furnace in the form of an oblong box
which is composed of suitable refractory material and the said furnace has a
number of holes formed through each side in order that the glass articles upon
their respective punties may be passed into and withdrawn from said furnace as
required. At either one or both ends of said box or furnace we arrange a burner
or burners or injectors in such a manner that the heat or flame therefrom may play
into the glowry hole or furnace, and said burners or injectors receive oil and steam
or other inflamable mixture for the purpose of combustion in a well known
manner.
The holes in the sides of furnace for the reception of the glass articles as
before described are arranged in alternate opposite positions so that the whole
of the available space within the furnace is economically used for the reception
of the glass articles being fire-polished and a maximum of impinging heat is
obtained with a minimum of waste. We prefer to carry our improved furnace upon
an iron carriage or frame work which may be conveniently moved to positions
required in the glass house.
It will be obvious however that where desired the said furnace may be a
fixture arranged alongside a melting furnace or fixed in any other convenient
position.
Upon the carriage or framework we arrange suitable carriers for supporting the
punties during the time the glass worker is fire polishing the glass articles.
It will be obvious by the particulars of our invention before described that the
flame or flames play from one end of the box or furnace to the other or from both
ends thereof during the time the glass articles are being revolved therein in the
usual manner.

Improvements in Glowry-holes for Fire-polishing Pressed or other
Glass Articles.
We HENRY HARLEY PITT of Low Fell, Gateshead-on-Tyne, in the County-
of Durbam, Engineer, and SOWERBY'S ELLISON GLASS WORKS LIMITED
of Gateshead-on-Tyne aforesaid, Glass Manufacturers, 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 an improved glowry-hole for fire-polishing pressed or
other glass articles, the object being to arrange or construct the same that a
number of glass articles may be expeditiously and efficiently fire-polished in the
least possible area or surface thereby economising the heat necessary for the said
fire-polishing; to attain which we arrange our improved glowry-hole substantially
as hereinafter described with reference to the accompanying sheet of drawings in
which
Fig. 1 is a side elevation of our improved glowry-bole,
Fig. 2 is a cross sectional elevation taken on line a a of Fig. 1. aud
Fig. 3 is a sectional plan taken on line bb of Fig. 1. and Fig. 4 is an end
elevation of the same, and
Fig. 5 is a sectional elevation of a modification of our said improved glowry-
hole.
Similar letters of reference denote corresponding parts in each view.
Referring to Figs. 1 to 4. we arrange a furnace in the form of an oblong box C
which is composed of suitable refractory material and the said furnace has a
number of holes formed through each side as shown in order that the glass
articles upon their respective punties c³ (see Fig. 3) may be passed into and
withdrawn from the furnace or box C as required.
At the end of the box C we arrange a burner or injector D in such a manner
that heat or flame therefrom plays into the furnace, glowry-hole or box C and the
said burner D receives oil and steam or other inflamable mixture for the purpose
of producing heat in a well known manner.
The holes e in the sides of the furnace or box C for the reception of the glass
articles as before described are arranged in alternate opposite positions as shown
at Fig. 3. so that the whole of the available space within the furnace is economically
used for the reception of the glass articles c being fire-polished and a maximum of
impinging heat is obtained with a minimum of waste.
We prefer to carry our improved furnace Cupon an iron carriage or
framework E which may be conveniently moved to positions required in the
glass house.
It will be obvious however that where desired the said furnace may be a
fixture arranged alongside a melting furnace or fixed in any other convenient
position.
Upon the carriage or framework E we arrange suitable carriers e for
supporting the punties c during the time the glass worker is fire-polishing the
glass articles in the usual way.
Referring to Fig. 5 it will be noticed that the furnace is longer and the box C
contains more holes c than that shown at Figs. 1. to 4. and a burner D is arranged
at both ends of said box C. It will be obvious that the flame from the burner or
burners or injectors D play from one end of the box or furnace C to the other or
from both ends thereof during the time the glass articles are being revolved
therein in the ordinary manner.

page_text: 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:
1. In glowry-holes for fire-polishing pressed or other glass articles arranging a
box or furnace C which receives flame or heat from one or both ends with holes c¹
through its sides at alternate opposite positions for the reception of the punties
and glass articles substantially as described and for the attainment of the object
specified.
2. The combination in a glowry-hole for fire-polishing pressed or other glass
articles of a furnace or box C having holes c¹ and burners or injectors D substan-
tially as described and illustrated.
