Improvements in Apparatus for Manufacturing Bottles and other
Hollow Glass Articles.
I, HOWARD MATRAVERS ASHLEY, of Ferrybridge, in the County of York, 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:-
In my Specifications No. 3673 of 1889 and No. 3686 of 1889 I have described
apparatus for manufacturing bottles and other hollow glass articles. My present
invention relates to improvements in such apparatus whereby I am enabled to
simplify their construction and facilitate their operation. To the single machine
described in the Specification No. 3686 of 1889, above referred to, I apply means of
moving the punch or plunger and paddle and of advancing and closing the finishing
mould and opening and withdrawing the same in the following manner.
On a
horizontal axis near the ground is pivotted a trendle lever which when depressed by
the foot of the operator raises a plate or table immediately under the punch or plunger
which is thus pushed up into the plastic glass in the parison mould and is then
withdrawn by a spring, forming a cavity into which the air for blowing is admitted
through the tubular punch. When the crank arm carrying the neck and parisou
mould is inverted the parison mould is withdrawn and the parison is partly blown,
the treadle is then again depressed raising the plate or table up against the glass and
thus paddling it, that is to say, somewhat flattening the bottom of the glass bulb,
whereupon the paddle is released. The operator now by means of his knee pressed
against a projecting lever arm moves a rocking frame which carries the paddling
plate and also the finishing mould, which he thus brings immediately under the
partly blown bottle. This mould consists of a mould for the bottom and two half
side moulds which are jointed to the bottom and are opened apart each inclining
outwards. The operator now by raising a lever, closes together the two half moulds
and then opening the air cock causes the bottle to be blown within the mould. When
the bottle is thus blown, the operator, pushing down the lever opens the mould and
then withdraws the rocking frame and mould leaving the bottle suspended by the
neck mould which is afterwards opened releasing the finished bottle.
To the repeating machine described in the Specification No. 3673 of 1889 above
referred to apply similar apparatus for moving the punch or plunger, advancing
and closing the finishing mould and opening and withdrawing the same, this apparatus
being fixed to act in one of the positions to which the moulding apparatus is brought
by turning the table partly round. Of these successive positions I employ three instead
of the four described in my former Specification. The three positions which I now

page_text: adopt are, first, that in which the molten glass is poured into the parison mould.
second, that in which the parison is punched, the mould is inverted, the part blowing
and the paddling are effected and also the blowing for finishing, third, that in which
the neck mould is opened releasing, the finished bottle which is removed to be
annealed.
In some cases, I perform in the first position of the mould all the operations
from the charging of the parison mould up to the removal of the finishing mould
in the second position I open the neck mould and remove the finished bottle, and in
the third position I grease the end of the punch and the nipple through which it
slides.
Instead of moving the revolving table to the successive positions by machinery as
formerly described, I now arrange it to be moved by hand. The inversion of the
parison mould after the punching, the opening and withdrawal of the parison mould
and also of the neck mould are effected by the operator, and both these moulds are
provided with weights or springs tending to close them when the effort of the
operator ceases. After release of the finished bottle the inversion of the turn over
moulding apparatus is effected as described in my former Specification No. 3673 of
1889 by the partial rotation of the horizontal table on which the three sets of
moulding apparatus are mounted.
When the bottle neck has an internal screw the nipple through which the punch
slides is made with a corresponding external screw and is arrangeri to be turned by
hand so as to unscrew itself from the bottle. This arrangement of screwed nipple
applies to the single machine as well as to the repeating machine.
Fig. 1 of the accompanying drawings is a side view, Fig. 2 is a front view and
Fig. 3 is a plan showing mechanism according to my present invention for punching
and paddling the parison and for raising closing opening and withdrawing the
finished mould as applied to a repeating machine carrying three sets of moulding
apparatus, such as are shown in the upper parts of Figs. 1 and 2.
These parts are
represented in the accompanying drawings in order to show the action with the parts
below in connection with them, but it is to be understood that they form no part of
the present invention, as they are included in my later Patent Application No. 129
of 1890.
A is the base and column carrying the revolving table B on which are mounted at
equal intervals three sets of the moulding apparatus C, each of which, as indicated
in Fig. 3 takes the successive positions C₁ C² C³. Assuming that at C, molten glass
has been introduced into the parison mould c which is at that time closed and
standing with its mouth upwards, then the lower part of the apparatus, to which the
present invention relates, is brought into action, this apparatus being constructed
and arranged as follows. On a centre d is mounted a rocking frame D) which is
partly balanced by a weight d connected to it by a chain pnssing over a pulley d².
The frame I can be rocked as far in each direction as is permitted by two adjustable
stops d³ d. When it is in the position shewn in Fig. 1 resting against the stop ³, a
sliding rod e carrying a plate or table E directly under the centre of the moulding
apparatus C can be raised by the operator depressing a treadle e which is linked
to the rod e. By this raising and then lowering of the plate E, the punch P of the
moulding apparatus is pushed up and returned downwards by its spring so as to
form a cavity in the plastic glass occupying the parison mould as described in my
former Specification above referred to.
The moulding apparatus C is then turned by band on its horizontal axis c'¹ so as to
present the parison mould c¹ mouth downwards, and the parison mould is opened, its
two halves being drawn aside leaving the plastic glass parison suspended by the neck
mould c² As shown in Figs. 1 and 2, the opening and closing of the parison
nould c is effected by the movement of a piston in a cylinder acted on by com-
pressed air or steam, but this, as above stated, forms no part of my present
invention. When the parison mould c is inverted and opened, a little air under
pressure is admitted through the tubular punch P (which is now uppermost) into the
cavity of the glass parison, and the operator by several depressions and releases of

page_text: the treadle & raises and lowers the plate E so as to effect the "paddling of the
parison, that is to say, somewhat flattening its bottom and bulging its sides as it
becomes gradually distended. The operator then pressing with his knee against a
bent stud do projecting from the frame D, pushes the frame over till it rests against
the stop in which position the finishing mould F is brought directly under the
centre of the moulding apparatus C. The finishing mould as shown consists of a
bottom part f and of two side parts fi f hinged and weighted so that they lie
apart both inclined outwards. They are linked to a crosshead f3 which is linked to a
double lever having their ends connected by a bar f. The operator applying his
hand to this bar raises the lever and crosshead f³ thus causing the two half
moulds to close towards each other enclosing within them the partly blown
parison. By the same movement the bottom mould which is on a sliding bar is
raised to the desired height, and, the mould being thus closed, the operator by fully
opening a cock or valve admits air under pressure through the tubular punch P to
the interior of the parison distending it to fit the finishing inould. The blowing
being effected the air cock or valve is closed by a spring and the lever
thus opening apart the sides f¹ f2 and lowering the bottom fƒ of the mould leaving
the blown bottle suspended by the neck mould c'.
is lowered,
The frame D being then rocked back to the position shown in Fig. 1, the finishing
inould is thus moved out of the way of the bottle, which, in the case of a single
machine, can at once be removed on opening the neck mould c², or which in the
repeating machine can be carried round by the revolving table to the next
position of the moulding apparatus, and can there be liberated by opening the
neck mould c².
Although I have shewn in the drawings mechanism for operating the punch,
paddling and working the finishing mould applied to a machine of the repeating
kind, in which the upper moulding apparatus C is moved round to three successive
positions, the same inechanism is obviously applicable to a machine which is not of
the repeating kind, the upper moulding apparatus C remaining always in one
position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be. performed I declare that what I
claim is

mechanism for punching and paddling the parison and for working the finishing
mould, consisting of a rocking frame carrying the paddling table and the finishing
mould, in combination with treadle and hand lever, arranged and operating sub-
stantially as herein described.
