Improvements in the Manufacture of Glass Bottles, Jars, or other
Hollow Articles.
We DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley in the County
of York, Glass Bottle Manufacturer, and BENJAMIN STONER of 2 Dearne Terrace
Stairfoot aforesaid, Mechanic, do hereby declare the nature of this invention to be as
follows:-
Our present invention relates to improvements in the manufacture of glass bottles
jars or other hollow articles for which Letters Patent No. 354 of January 10th 1887
were granted to us.
According to our present invention we cut into the neck of the mould, into which
the molten glass is run from a Syphon pipe or ladle, the exact shape of ring which
we wish the bottle mouth to have externally and we use a blow pipe the exact shape
we wish the bottle mouth to have internally.
This blow pipe we construct having a hole fitted with a special valve which valve
so arranged that the turning of a handle or tap in one direction closes the hole
whilst the turning of it in the other withdraws the valve allowing the air to pass
through.
This short blowpipe is so arranged that it can be easily blown through by
compressed air either from a vessel close by the mould or by means of a pipe connection
which is easily adjusted.
The mould bottom we form moveable and immediately the molten glass is poured
or run into the mould and the mould closed the bottom is caused to travel thus
compressing the molten glass and forcing it on the hollow blow pipe. The bottom is
then withdrawn to its proper position and compressed air is forced into the molten
glass the valve in the blowpipe being released to allow of the air passing.
Whilst this is being done we cause the mould and the blow pipe to revolve.
After
the bottle has been blown up the blow pipe is either withdrawn from the mould or the
mould withdrawn from the blowpipe.

page_text: One half of the mould is then left open and the bottle can then be taken away from
the other half to the annealing arch. During the process the mould is fixed
horizontally.
The moveable bottom may be made to work with a foot lever or in any other
suitable way.
In making Globe Stoppered Bottles we use a blow pipe and a special plug―The
pipe is of so large a diameter that it leaves the mouth wide enough to receive a glass
ball. This blow pipe we fit with a pair of dogs for cutting the groove for receiving
the India Rubber washer or for shaping the mouth to receive a conical stopper.
After the mouth has been formed with this blowpipe fitted with these dogs we
withdraw this pipe; a glass ball is then introduced into the bottle and a plug
smaller than the blow pipe is passed into the mouth and a pair of suitably shaped dies
from the outside are forced upon the mouth thus compressing it so that the glass
ball cannot be blown out again.
Our present invention is also applicable to a class of bottle that we desire to make
having two glass lugs formed on the top of the mouth which lugs are so formed
as to allow of a piece of wood being passed under them in order to hold the cork
or stopper with which the bottle is closed. In order to form a bottle of this
particular shape we cut in the mould neck of the iron bottle mould two indentations
and we so shape the short blow pipe that the groove can be formed in the glass
lugs which are pressed into these indentations-This leaves the bottle mouth with
glass lugs on each side into which a wood disc can be forced.
We also apply our present invention to the manufacture of external screw mouth
bottles by cutting a screw in the mould neck and by means of our hollow blow
tube the mouth is formed inside.
Where it is desired to form a screw thread inside the bottle neck we cut a screw
on the blow pipe which will be well understood.
In the latter case the short hollow blow tube is screwed out from the bottle mouth
after the bottle has stopped revolving.

We DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley, in the County
of York, Glass Bottle Manufacturer, and BENJAMIN STONER of 2 Dearne Terrace,
Stairfoot aforesaid, mechanic, 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 relates to improvements in the manufacture of glass bottles,
jars, or other hollow articles for which Letters Patent No. 354 of January 10th
1887 were granted to us. According to our present Invention we cut into the
neck of the mould (into which the molten glass is run from a syphon pipe or ladle)
the exact shape of ring which we wish the bottle mouth to have externally, and
we use a blowpipe the exact shape we wish the bottle mouth to have internally.
This blow pipe we construct having a hole fitted with a special valve which valve is
so arranged that the turning of a handle or tap in one direction closes the hole,
whilst the turning of it in the other direction withdraws the valve allowing the air
to pass through. This short blowpipe is so arranged that it can be easily blown
through by compressed air either from a vessel close by the mould or by means of a
pipe connection which is easily adjusted.
The mould bottom we form moveable, and immediately the molten glass is poured
or run into the mould and the mould closed, the bottom is caused to travel thus
compressing the molten glass and forcing it on the hollow blowpipe. The bottom
is then withdrawn to its proper position and compressed air is forced into the molten
glass, the valve in the blowpipe being released to allow of the air passing. Whilst
this is being done we cause the mould and the blowpipe to revolve. After the bottle
has been blown up the blowpipe is either withdrawn from the mould or the mould
withdrawn from the blowpipe. One half of the mould is then left open and the
bottle can then be taken away from the other half to the annealing arch. During
the process the mould is fixed horizontally. The movable bottom may be made to work
with a foot lever or in any other suitable way.
In making Globe-Stoppered Bottles we use a blow-pipe and a special plug. The
pipe is of so large a diameter that it leaves the mouth wide enough to receive a glass
ball. This blowpipe we fit with a pair of dogs for cutting the groove for receiving
the India Rubber washer or for shaping the mouth to receive a conical stopper.
After the mouth has been formed with this blowpipe fitted with these dogs, we with-
draw this pipe. A glass ball is then introduced into the bottle and a plug smaller
than the blowpipe is passed into the mouth and a pair of suitably shaped dies from
the outside are forced upon the mouth, thus compressing it so that the glass ball cannot
be blown out again.
Our present Invention is also applicable to a class of Bottle that we desire to make
having two glass lugs formed on the top of the mouth, which lugs are so formed as
to allow of a piece of wood being passed under them in order to hold the cork or
stopper with which the bottle is closed.

page_text: In order to form a bottle of this particular shape we cut in the mould neck of the
iron bottle mould two indentations, and we so shape the short blowpipe that the
groove can be formed in the glass lugs which are pressed into these indentations.
This leaves the bottle mouth with glass lugs on cach side into which a wood disc can
be forced.
We also apply our present Invention to the manufacture of external screw-mouth
bottles by cutting a screw in the mould neck, and by means of our hollow blow-tube
the mouth is formed inside.
Where it is desired to form a screw thread inside the bottle neck we cut a screw on
the blowpipe, which will be well understood. In the latter case the short hollow
blowtube is screwed out from the bottle mouth after the bottle has stopped
revolving.
In order that our Invention may be more particularly understood and more fully
described, we hereunto attach drawings of which the following is a description, similar
letters of reference being used to indicate similar parts
Fig. 1 is an elevation partly in section, and Fig. 2 a plan also partly in section, of
our improved bottle making machine. Fig. 3 is a sectional elevation, and Fig. 4 an
end elevation of bottle mould. Figs. 5, 6, and 7 are sections of moulds for producing
different types of bottle mouths; and Fig. 8 an elevation of the mouth shown in
section in Fig. 7. Fig. 9 is an elevation of end of blowpipe.
In Fig. 1a is the bottle mould formed in two halves, and hinged together; is a
plunger attached by rod c to handle d; e is a blowpipe shaped to fit the mouth of the
bottle is the tap admitting compressed air. The guide containing annular
wearing ring his for the purpose of holding the two halves of the mould together
centrally around the stationary blowpipe. The pinion and spur wheel actuated by
hand wheel rotates the mould a through hollow sleeve working in bearings m.
The carriage or foundation on which the machine is fulcrumed by pin o allows the
machine to be set at the required angle; p and q are slides set to work at right
angles to each other.
In Fig. 2 are dogs connected by links ss to sliding sleeve t; is a handle
actuating slide P and a spring tool.
Fig. 3 is an enlarged view of bottle mould, hinged at w, and held together during
rotation by latch a engaging with pin y..
Fig. shows the arrangement, adopted for opening and closing the neck portion of
the mould, the two halves of which are hinged together at 1, enclosing and revolving
with the body of the mould a. In this view the neck portion is shown in the shut
and open positions.
The action of the machine as shown in Fig. 1 is as follows:-The uppermost
portion of the mould a having been raised or opened, the requisite quantity of metal
is ladled or syphoned into the mould, the mould then being closed and secured by
the latch shown in Fig. 3 at a. The plunger by action of the lever & now forces the
metal into, to, and about the neck portion of the mould, filling up and occupying the
space between the exterior of the blowpipe e and interior of the neck of the mould,
thus forming the neck or mouth of the jar shown. The plunger 6 being now with-
drawn will leave the metal in a position to be expanded by air pressure to the contour
of the mould; and during the time air is being admitted the mould is rotated by
hand wheel k. This being accomplished, and the bottle or jar having acquired the
desired figure, the guide g is withdrawn by means of slide p, when the upper portion
of the mould can be opened and the finished bottle withdrawn.
b
The process as shown in Fig. 2 is similar to the one just described as regards the
filling, plunging, rotating, and application of air pressure; but the blowpipe is in this
case fitted with dogs for the purpose of forming an annular groove in the neck
portion for the reception of the rubber ring required for this description of bottle.
The metal having been forced into the neck portion and the mould rotated, compressed
air being at the same time admitted, the result will be as previously described in the
metal assuming the form of the mould. After this the air being shut of, and the
mould continuing to rotate, the dogs are operated by means of the sliding sleeve t and

page_text: links ss resulting in the formation of the groove required. The guide g being now
withdrawn by the slide p, and the neck portion of the mould being opened as shown
at (Fig. 4), the carriage p¹ and slide p are free to move along the slide 7 by reason
of the dogs being now withdrawn from the mouth of the bottle. The globular stopper
is then put into the mouth of the bottle, after which the central plug is brought into
position centrally with the mouth of the bottle, and by the action of the lever u enters
the mouth of the bottle; the mould is again rotated, and pressure being exerted by
the hand of the workman upon the legs of the spring tool t forces the dies v² together,
thus causing the neck to be contracted and altered in form from that shown in Fig. 3
to the figure required in the finished bottle. It will be seen that this finishing opera-
tion so alters the formation of the month that the spherical or other stopper will be
enclosed and prevented from being blown out again by any pressure that may be
brought to bear upon it.
Fig. 5 shows in section the arrangement of threaded blowpipe e and mould a. The
blowpipe being placed in position by action of slide p, the plunger b will force the
metal into the space between interior of mould and the exterior of threaded blowpipe
after which on the bottle being completed the pipe can readily be unscrewed and
withdrawn from the bottle.
In Fig. 6 the method of
threaded bottle is shown,
to form the groove to the
shown by Fig. 2.
forming the annular groove in the mouth of an externally
being the dogs for cutting the groove, and which are set
desired depth by means of the sliding sleeve t, as fully
Fig. 7 shows a mould, blowpipe, and dogs arranged to form a bottle neck with the
projecting lugs shown at 4 4, a being the mould, e the blowpipe, and the dogs for
forming the undercuts or recesses shown at 5, 5. The neck portion and lugs being
formed as previously shown, the dogs are caused to recede inwards towards the
blowpipe and freeing themselves from the undercuts, when the blowpipe and its
accompanying dogs can be withdrawn from the bottle.
Fig. 8 is an elevation showing one of the projecting lugs 4.
Fig. 9 shows an end view of blowpipe, 6 being the hole for admission of air, the
dogs, and 7, 7 the recesses into which the dogs recede.
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 connection with bottle making machines the use of dogs for forming grooves
in bottle mouths.
2. In bottle making machines, the special arrangement herein described and
illustrated for contracting size of bottle mouth after stopper has been put in.
3. In combination with bottle making machines, the use of moulds having screw
threads cut or formed on the neck of the mould.
4. In combination with bottle making machines, the use of a blow tube having a
screw cut on it for the purpose of forming an internal screw in the bottle mouth.
5. The formation of glass lugs on the top of bottle months.
