PROVISIONAL SPECIFICATION.
Improvements in Machinery for the Manufacture of Bottles.
I, DAN RYLANDS, of Hope Glass Works, Stairfoot, near Barnsley, in the County of
York, Glass Bottle Manufacturer do hereby declare the nature of this invention to be
as follows:-
According to my present Invention I form a mould having a bottom through
which a tube, made of iron or other suitable metal, can be forced or propelled.
This tube will vary in internal diameter and in length according to the size of the
Bottle that is required to be made. By a suitable lever or other attachment, this tube
is forced up into the mould, and the molten glass is poured into this tube until it is
sufficiently full for the purpose of making the bottle required. On the top side of this
tube that portion of the mould which is intended to help in the formation of the neck
of the Bottle is fixed and closed by means of side hinges and fastenings, or in any
other suitable way.
After this has been closed a tapered pin is forced down through
the centre of the molten glass in the tube to within say one inch of the bottom or
any other suitable distance. The forcing of this pin thus down through the molten
glass compresses a portion of the molten glass into the portion of the mould for
forming the neck, and the top part of the pin is so adapted as to form the top ring
of the Bottle. The tube and the pin are then withdrawn from the mould, and the top
portion of the mould which roughly forms the neck of the Bottle is unfastened and
removed, and a second top portion the exact shape that the neck of the Bottle is
required to be is put on the top of the mould. Compressed air is then blown into
the molten glass either through a tube in which the pin which forms the hole may
work, or in any other suitable way, and the Bottle is thus blown out to the proper
size of the mould.
Where it is desired to form an annular groove in the top part or lip of the
Bottle, I fit suitable dogs either into the before-mentioned pin or into a second pin
introduced before the glass has had sufficient time to congeal or stiffen.

page_text: In combination with the hereinbefore described arrangements I adapt plugs for
forming screw mouths in the inside of the Bottle neck.
I wish it to be well understood that at any time during the process herein described
I revolve the mould at any speed that may be required for the better manufacture of
the Bottles.
Improvements in Machinery for the Manufacture of Bottles.
I DAN RYLANDS, of Hope Glass Works, Stairfoot, near Barnsley, in the County
of York, Glass Bottle Manufacturer 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:-
My Invention relates to a process of making globe-stoppered Bottles, ordinary
Bottles, Jars, or other hollow ware in glass.
In order to make my Invention more clearly understood, I have annexed hereunto
three sheets of drawings, to which the following description relates, and in which the
same letters or figures of reference indicate the same parts.
Fig. 1 is an elevation; Fig. 2 a plan of table showing position of moulds; Fig. 3
an elevation partly in section showing one complete mould and apparatus for
operating same; Fig. 4 a plan view of mould and mould-actuating apparatus ;
Fig. 5 a sectional view of blow pipe admission valve; and Fig. 6 an elevation of
same.
Referring to Fig. 1 a is a pillar supporting bracket b, at the outer end of which is
formed a tubular guide e for the reception of the sliding ramd; e is a lever ful-
crummed at f and connected to ram
by link 9 3 h is a balance weight, i a
tapered pin secured to and carried by ram d; a table capable of intermittent
rotary movement around the central pillar a; kk are bottle moulds carried by
studs l l. The method of opening and closing the different portions constituting
the complete mould is shown more fully in Figs. 3 and 4. The detents m m are
capable of dropping into recesses formed in sector n; o o. are handles operating
detents m m through shafts h h; qq are circular paths formed on the framing r
the angular outer pathway 9 being formed with a double incline or depression
having its greatest depth at a' (Fig. 2) and rising to the level of the otherwise
level pathway at a², a³. The inner pathway g' has also a rising and falling incline
extending from a to a³, attaining its greatest height at as, the other portion of the
pathway being level.

page_text: Fig. 2 shows the revolving table with the bottle moulds 1 to 8 arranged
around its outer circumference; 1 is the ladling or charging; 2 the pressing, and
3 the blowing positions; 4 and 5 the reheating, 6 the neck forming and grooving,
and 7 the position of the mould previous to opening, as shown at 8, for the removal of
the finished Bottle.
Figs. 3 and 4 show one mould and the mould-operating mechanism; ssss are stationary
cams secured to central pillar a; tttt are plungers having bearings in guide w;
are runners or bowls carried by plungers t; y spiral springs carried by the
stem of the plunger and shown at y (Fig. 4); 9 connecting links between the
different sections of mould and plunger guides 10. The mould shown is arranged
to make globe-stoppered Bottles, is open at top and bottom, and is built up in
sections, each section being hinged, and capable of opening. The bottom section 11
has an internal diameter equal to the external diameter of the Bottle to be made,
and constitutes the body portion; 12 is one of the neck moulds of smaller diameter
than the intended neck; 13 is the portion forming the mouth of the Bottle; 14 a
neck mould having its internal contour formed so as to produce a Bottle neck of
the full size required; 15 a sliding tube working through the bottom of the Bottle
mould and actuated by runner 16 and inclined plane q'; 18 inner portion of mould
bottom having movement given to by runner 19 and incline q; 21 shows the
intended Bottle in its first stage after the plunging process.
Fig. 5 is a sectional elevation of blow-pipe admission valve, in which 22 is the valve,
23 the casing, and 24 an attachment secured to valve stem 25. The rod 26 is
connected with handles oo (Fig. 1) in such a manner that upon one of the handles being
raised to allow of the rotation of the table j, the rod 26 will raise the air-admission
valve and blowpipe; and upon the handle being depressed (through reason of
detent m falling into recesses in sector n) the admission valve will fall into its
lowest position; the attachment 24 coming in contact with upper portion of mould
will raise the admission valve, and blowing will commence and will continue
until one of the handles is again raised for the further rotation of the table and
moulds.
Having now explained the various parts appertaining to my Invention, 1 pro-
ceed to show the method adopted in producing a Bottle. Referring to Figs. 2, 3,
& 4, 1, shows a mould in the ladling or charging position, the bottom portion of
the mould 11 (Fig. 4) being closed. The neck 12 (Fig. 4) and mouth portions 13
open as shown, the tube 15 being at its highest and the inner portion of mould
bottom 18 at its lowest position. It will be seen that the molten metal is charged
into and contained by the space surrounded by the tube and inner portion of
mould bottom. The table and the charged mould being now rotated into position 2
will result in the upper portions of the mould 12 12 closing by reason of fixed
cams s, bowls, plungers t, and links g, and assuming the position shown at 2.
The iuner portion of mould bottom 18 in the meantime by means of inclined pathway
and runner 19 assumes its highest position as shown at Fig. 3. The tapered pin
being now operated by lever e will result in the molten metal being pressed into
the form shown at 21 (Fig. 3). The pin being withdrawn and the table
again rotated will cause the opening of the neck mould 12, and the closing of the
mould 14 intended to produce the form of neck usual in a globe-stoppered
Bottle. The tube by incline and runner 16 will now have fallen to nearly the
bottom of the body mould 11 and level with the inner portion of mould bottom 18, the two
conjointly forming the bottom of the bottle mould and being shaped to produce the
form of bottle bottom required. The mould containing the pressed Bottle will now
have arrrived at 3, the blowing position, and the conical projection shown on the
admission valve casing will occupy the seating provided for it on the upper surface
of the mould 13 as shown in Fig. 5. The admission valve being raised by attach-
ment as shown will result in blowing being continued till the handle is again lifted ;
4 and 5 are the reheating positions, and the mouth portion of the mould being now
opened will cause the mouth of the Bottle to be exposed and subject to the flame of
reheating burners, heating the mouth portion and rendering it fit for the mouth

page_text: forming and grooving operations. The ball stopper being now placed in the neck,
the mouth forming and grooving apparatus described in a former Patent granted to
myself and Benjamin Stoner, No. 17543 of 1887, is brought into play, the grooving
and forming tools there described as stationary having in this case a revolving move-
ment. The mouth of the Bottle being now reduced and formed to the desired
figure the Bottle is completed and ready for removal from the mould, which can be
done when the mould arrives at 8.
For the sake of clearness I have described the action of one mould through
the whole of the processes requisite to produce a finished Bottle. But there being
eight moulds it will be evident that the whole of the processes can be proceeding at
one and the same time; that is to say, whilst the molten metal is being charged into
one mould, pressing, blowing, re-heating, mouth-forming, and delivering are taking
place in the moulds 2 to 8; and that as each mould arrives at position 8 a finished Bottle
will be produced.
It will be clear that by a modification of the moulds, any form of Bottle or Jar can
be produced. Provision is made whereby the moulds become locked and firmly held
together whilst subject to the pressing and blowing operations as will be well
understood.
It will be well understood that the tube referred to in the foregoing specification
may be of any suitable shape or size, and that it will vary according to the size or shape
of the Bottle required to be made.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:
1. The combination with a Bottle mould of a tube capable of being propelled or
forced by any suitable mechanism into the inside of the mould through the
mould bottom and of being withdrawn again from the inside of the mould.
2. The special mechanical arrangements and attachments for forcing or propelling
the tube into the Bottle mould as herein described and illustrated with reference to
Figs. 1 and 3 of the accompanying drawings..
3. In combination with the tube the use of a taper pin for the purpose herein
described and illustrated.
4. The special mechanical arrangements for withdrawing the tube and pin from
inside of the Bottle mould as herein described and illustrated with reference to Figs. 1
and 3 of the accompanying drawings.
5. The special mechanical arrangements herein described and illustrated for removing
the first top portion and second top portion of the Bottle mould.
Dated this 1st day of December 1888.
