Improvements in the Manufacture of Glass-lined Fittings for
Glass-lined Piping.
We, DAN RYLANDS, of Shepcote, Stairfoot, near Barnsley, in the County of
York, Glass Bottle Manufacturer, and ALFRED HUSSELBEE, of Hunningley Lane,
Stairfoot, aforesaid, Glass Tube Drawer, do hereby declare the nature of this
invention to be as follows:-
In carrying out our invention for the manufacture of glass bends we take a mould
made of iron or other suitable metal or material & made in two halves and jointed
so that it will readily open. To one end of this mould we attach a small box so as
to the more readily enable the bend to be blown out to the exact internal size of
the mould and yet to afford a chance of the glass expanding wider in the said box
so that it can be easily ground off when the glass is cold. Whilst the mould is open
we take a piece of molten glass drawn into tube form and we place it in the mould
for forming the bend and bend the glass round to the internal configuration of the
mould. We then close the mould which brings the edges of the box at one end of
the mould down upon the hot tube thus cutting it off at one end, and the operator
blows at the other end until the bend has been blown up to the full size of the
mould after which he bursts off the other end in the way known in the trade as
blowing a "burst-off." The mould is then opened and the bend taken out and after
it is cooled the one end which has been blown up in the box is easily ground off
whilst the other being burst off only requires grinding on a stone to level it.
Another way of making this bend is to first draw a small length of tube, break off
one end and retain the other end on the blow pipe and after re-heating such end dip
it in the pot of metal thereby sealing one end air-tight with hot metal. The hot
tube is then bent round in the mould for forming the bend or elbow and is blown up
in the way previously described.
In applying our invention to tee pieces we take a cold glass tube of say six feet.
in length and warm one end of such tube in the furnace to a good red heat. We
then dip this tube in the metal in the pot so as to form a seal at one end and we
then pass the hot end of this tube through an iron tee piece. Immediately this hot
tube is in the proper position we drop some hot metal through the vertical portion
of this iron tee piece, and by blowing through the cold end of the tube we force a
hole through the centre of the tube up the vertical portion of the iron tee and
through the molten glass which has been dropped in such vertical portion. Another
way of securing this is by gathering a small quantity of metal on the end of a blow
pipe and by so passing this metal through the horizontal portion of the tee piece
that the metal can be blown out to the size and shape required; in this case the
hole is first blown through the glass in the horizontal portion of the tee-piece, and
then a little hot glass is dropped down the vertical portion of the tee-piece and the
pressure of air being applied to the glass forces a hole through the molten glass thus
dropped in the vertical portion of tee piece.
In making crosses we first blow up the one vertical portion and then screw on an
air-tight cap, then drop hot metal into the corresponding vertical portion and then
blow this through. In thus blowing the glass lining to the tee pieces and crosses it
is necessary that the tee pieces and crosses have a layer of either wood, wood pulp,
carbon, plaster of Paris or any other suitable lining or substance between the glass
and the iron, both in the horizontal and in the vertical portions of the tee pieces or
crosses.

Improvements in the Manufacture of Glass-lined Fittings for
Glass-lined Piping.
We, DAN RYLANDS, of Shepcote, Stairfoot, near Barnsley, in the County of
York, Glass Bottle Manufacturer, and ALFRED HUSSELBEE, of Hunningley Lane,
Stairfoot, aforesaid, 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 :-
Fig. 1 shows a mould C such as according to our present invention we use for
making glass bends. This mould is made in two halves and hinged so that it will
readily open.
B is a small circular or other shaped box which we form at one end
of this mould for making the burst off at the end of the mould. D shows the solid
end of the tube which is blown out to form the "burst off." We find it best not to
cut the end of the hot tube A when we are closing the mould but to first blow the
bend up to its full size whilst the tube is attached to the glass and then to wet off
the end at which the blowing tube E is. A bend thus formed is easily ground at
each end after it has been taken out from the mould and annealed or cooled off.
Or we first gather the metal for a small length of tube and by means of a pair of
pincers we pull this tube to the requisite form, then close the mould, and by
blowing, a "burst off" is formed at one end, whilst the other end can be cut off or
"wet off" in any suitable manner. This second plan will be well understood
without drawings.
Another way of making this bend is to first draw a small length of tube
break off one end and retain the other on the blow pipe; and after re-heating such
end close it hermetically either by means of a little hot metal or by a pair of tools.
Then bend the hot tube round in the mould for forming the bend or elbow and blow
up in the way previously described.
it
Figs. 2 and 3 show our present invention as applied to the manufacture of tee
pieces or crosses.
We take a piece of glass tube A of any suitable length and warm one end of
such tube in the furnace to a red heat. We then seal the hot end of this tube either
by closing it over with a pair of tools or with some hot metal from the pot. We
then pass the hot end of this tube through an iron tee piece F such iron tee picce
having been heated sufficiently hot before the glass is put therein. Immediately
this hot tube A is in the proper position we drop some hot metal through the
vertical portion G of this iron tee piece, and by blowing through the cold end of
the tube we force a hole up the vertical portion H thus forming a glass tee.
Another way of making these tee pieces or crosses is by gathering a small quantity
of molten glass on the end of a blow pipe and by so moulding this metal that it can
be easily passed through the horizontal portion of the tee piece. After it has thus
been passed through the horizontal part a little hot metal is dropped down the
vertical part, the sticking puntil J which is used for dropping this metal being kept
attached to it so as to help to pull the metal up as the blower blows the molten
glass up from the horizontal portion of the glass tec and thus a complete tee is
formed. In making crosses we first blow up the one vertical portion H' and make
it airtight in any suitable manner. We however prefer to do so by pincering the
glass close or cutting it off the blow tube out of solid metal at the end of such blow
tube. We then drop hot metal into the opposite vertical portion H and blow this
up, the blowing being assisted by the gentle raising of the puntil J which carries
the hot metal.
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. The improved mould for the manufacture of glass bends as set forth and
described with reference to Fio. 1 of accompanying drawings.

page_text: 2. The improved process of manufacturing glass bends as described in connection
with the working of the said moulds or any mere modification thereof.
3. The improved process for the manufacture of glass tees and glass crosses as
shown and described with reference to Figs. 2 and 3 of the accompanying drawings
or any mere modification thereof.
