PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Fire Polishing Tubes or other
Hollow Glass Ware.
We, DAN RYLANDS of Shepcote House Stairfoot near Barnsley in the County
of York, Glass Bottle Manufacturer, and ALFRED EDWARD HUSSELBEE,
Hunuingley Lane, Stairfoot aforesaid, Glass Tube Drawer, do hereby declare the
nature of this invention to be as follows:-
Our present invention has for its object the fire polishing of tubes such as boiler
gauge tubes and other similar glass ware in such a manner that the fire polishing
is done much more rapidly and economically than on the system at present in use.
According to our present invention we form a disc plate having any required
number of holes each hole being the size of the tube which we desire to fire polish.
To this plate is attached a stem or handle of iron or other suitable metal and on
this handle we fit a circular disc which is adjustable to any required length and is
so arranged that the tubes are dropped in through the holes in the end plate. The
ends of these tubes rest on or in this disc. This disc is adjustable by means of a
lever or screw or other arrangements so that the end of the tubes can be pushed
forward through the holes in the circular plate just far enough for enabling them
to be exposed to the flame of the furnace in the working hole. After thus fitting
these tubes we place them with the ends in the working hole of the furnace and
slowly turn these tubes round so that they are gradually and regularly heated until
they are brought nearly to the melting point when they are withdrawn and are
then thoroughly fire-polished. After fire-polishing one end of these tubes we
reverse the tubes and expose in a similar manner in the working hole the other end
which has not been fire-polished and thus each end of the tube is fire-polished.
Our improved plan of fire polishing is equally applicable where the ends of the
tubes are exposed to a gas flame instead of the heat in the furnace. Also to other
hollow glass ware.

Improvements in Apparatus for Fire Polishing Tubes or other
Hollow Glass Ware.
We DAN RYLANDS of Shepcote House Stairfoot near Barnsley in the County
of York, Glass Bottle Manufacturer, and ALFRED EDWARD HUSSELBEE,
Huuningly Lane, Stairfoot aforesaid, Glass Tube Drawer 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 has for its object the fire polishing of tubes, such as boiler
gauge tubes and other similar glass ware in such a manner that the fire polishing
is done much more rapidly and economically than by the system at present in use.
In the accompanying sheet of drawings,
and
Fig. 1 is an elevation partly in section of our improved fire polishing apparatus.

In Figs. 1, 2 and 3, a is a disc plate perforated with any suitable number of holes
each hole being rather larger than the tube which we desire to fire polish, ba stem

or handle firmly secured by riveting or otherwise to the disc plate a, c a disc plate
also perforated with holes of the same size and number as the disc plate a, da
circular non-perforated end plate; e a circular distance piece or boss, to which the
two disc plates are secured by riveting; a set screw securing the combined
discs e and d to the stem and enabling the distance between the discs a and a to be
readily adjustable so as to suit the lengths of tubes it is desired to fire polish.
The tubes being inserted in the apparatus after the manner shown by Fig. 2
are placed in the working hole of the furnace and slowly rotated so that they may
become slowly and gradually heated until the end portions are brought nearly to
the melting heat when they are withdrawn and are then thoroughly fire polished.
After fire polishing one end of the tubes we reverse the position of the tubes and
expose in a similar manner in the working hole, when both ends of the tubes will
have become fire polished.
Our improved system of fire polishing is equally applicable where the ends of
the tubes are exposed to a gas flame instead of the heat in the furnace. It will
be seen that our system of fire polishing is applicable to other forms of hollow
glass ware that can be conveniently held and rotated in the above described
apparatus or modifications thereof.
It will be well understood that there may be a variety of shapes of the apparatus we
have illustrated without departing substantially from the principle of our invention
which is for fire-polishing a quantity of tubes at one time.
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
I. The apparatus for using in the process of fire-polishing tubes substantially as
described with regard to Figures 1, 2 and 3 of the accompanying drawings or
any mere modifications thereof.
II. The improved arrangements for fire-polishing of tubes whereby a quantity of
such tubes can be fire-polished at one operation.
