Improvements in the Manufacture of Glass Taps and Glass Tees and
other Hollow Glass Ware.
We, DAN RYLANDS of Stairfoot near Barnsley in the County of York Glass
Bottle Manufacturer and BENJAMIN STONER of Hopewell Street, Stairfoot near
Barnsley aforesaid Mechanical Engineer, do hereby declare the nature of this
invention to be as follows :-
According to our present invention we make a mould of cast iron or other
suitable substance which mould opens in two or more parts and is constructed with
a get-hole for the molten glass to pass through into this mould with, which it is
intended to make the tap or tee piece. Over this get-hole we fix or form a box
for receiving the molten glass which box is sufficiently large to receive enough
glass for the tap or other hollow glass ware that we wish to make. Over this box
we fit a suitable plunger carried by means of a lever or screw or other suitable
arrangements. Having fixed the mould in a suitable position for receiving the
molten glass which may be either laded or otherwise run into it we introduce into
the mould iron core pieces which core pieces are moved into the mould by means
of lever or screw arrangement. The important point in such arrangement is that
they must carry these core pieces perfectly central and true into the inside of the
mould. In making a three way tap we should have four of these core pieces that is.
three of them for forming the inlets & outlets and one core piece for forming the
hole for the controlling plug or tap to work in. After these core pieces have all
been brought into their proper position in the mould we pour or lade the molten glass
into the box over the get hole and by bringing the plunger down upon this molten
glass we force the molten glass into all the space in the mould round each of the
cores and after allowing sufficient time for the glass to settle we withdraw all the
cores at the same time blowing in through each core if necessary any required
quantity of cold air to keep the glass from losing its true shape. In making a
tee piece we use three cores. In making a cross we use four cores. In making an
elbow we use two cores working at right angles. Where it is required to have a
screw of any kind formed on the glass we form such screw on the inside of the
mould or if an internal screw were required we would then form a screw on the
cores only in this case the core would have to be screwed out instead of being.
drawn straight out.
It will be well understood that we can make either one way or two way or three
way or four way taps according to our present invention.
According to our present invention we form collars on each core in such position
as to stop the cores at exactly the right place when they are being pushed into the
mould.

Improvements in the Manufacture of Glass Taps and Glass Tees and
other Hollow Glassware.
We DAN RYLANDS of Stairfoot near Barnsley in the County of York, Glass
Bottle Manufacturer and BENJAMIN STONER of Hopewell Street Stairfoot near
Barnsley aforesaid Mechanical Engineer 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 :-
According to our present invention we make a mould of cast iron or other
suitable substance which mould opens in two or more parts and is constructed with
a get-hole for the inolten glass to pass through into this mould with which it is
intended to make the tap or tee-piece. Over this get-hole we fix or form a box for
receiving the molten glass which box is sufficiently large to receive enough glass
for the tap or other hollow glassware that we wish to make.
Over this box we fit
a suitable plunger carried by means of a lever or screw or other suitable arrange-
ments. Having fixed the mould in a suitable position for receiving the molten
glass which may be either laded or otherwise run into it we introduce into the
mould iron core pieces which core pieces are moved into the mould by means of a
lever or screw arrangement. The important point in such arrangement is that
they must carry these core pieces perfectly central and true into the inside of the
mould. In making a three-way tap we should have four of these cores, that is
three of them for forming the inlets and outlets and one core-piece for forming the
hole for the controlling plug or tap to work in. After these core pieces have all
being brought into their proper position in the mould we pour or lade the molten
glass into the box over the get-hole, and by bringing the plunger down upon this
molten glass we force the molten glass into all the space in the mould round each
of the cores, and after allowing sufficient time for the glass to settle we withdraw
all the cores; at the same time blowing in through each core if necessary any
required quantity of cold air to keep the glass from losing its true shape.
We attach drawings to enable our invention to be more clearly understood.
Fig. 1 is an elevation in section of a mould and apparatus suitable for the
production of a three-way tap or similar article,
Fig. 2 being a plan view thereof.
In Figs. 1 and 2 a is the bottom half-portion of the mould working in slides on
the upper surface of the table b; the upper portion of mould provided with
dowels or pins that find a seating in corresponding holes formed in the upper
surface of lower portion of mould; c¹ a charging box for the reception of the
molten metal; d the pressing plunger; e e rods actuated by screw or equivalent
arrangements for the purpose of holding the charging box securely upon the upper
surface of mould during the pressing operation; fff are cores guided by the
tubular guides ggg; hhh are stop collars formed on the cores ensuring the cores
entering the mould to the desired position; the gait for the entrance of the molten
metal into the interior of the mould; ; the body core guided by the mould as shown
by Fig. 2.
The method of producing a three-way tap by the above-described apparatus is
as follows: The cores being in the position shown by the drawings, the plunger
being elevated and occupying it highest position, molten metal is charged into the
interior of charging box e.. The plunger now descending displaces the metal from
the charging box into the interior of the mould causing the metal to fill and fit the
interior space of the mould not occupied by the cores. The formation of the tap
being now complete the cores are simultaneously withdrawn by lever or other
action. During the time of withdrawal cold air under suitable pressure is admitted
by holes or ports k formed in one or all the cores cooling the metal and causing it
to retain its original formation till sufficiently set to be removed from the mould
which is done in the usual manner.

page_text: If it be desired to form a tap having external coupling threads, then the interior
of the mould will be screw-threaded as shown at 1 (Fig. 1).
If an internal thread is required the cores will carry the screw-thread, and instead
of being withdrawn from the mould will require to be rotated from it which can be
done in any suitable manner.
It will be seen that the apparatus is applicable to the manufacture of tees,
crosses, elbows, one-way, two-way, and three-way taps, by the employment of
suitable moulds and the required number of movable air-admitting cores.
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 combination of the several parts herein described and illustrated for the
manufacture of glass tees, taps, crosses, elbows, and other hollow glassware
II. In the manufacture of glass tees, taps, crosses, elbows, and other hollow
glassware the use of air-admitting cores in the manner described.
III. The process herein described for forming internal and external screw
threads on glass tees, taps, crosses, and similar glassware.
