Improvements in or applicable to Machinery for the Manufacture
of Bottles or other Hollow Glass Ware or Pressed Ware.
I, DAN RYLANDS, of Stairfoot near Barnsley in the County of York, Glass
Bottle Manufacturer do hereby declare the nature of this invention to be as
follows:-
Under
My present invention has for its object improvements in machinery for the
manufacture of bottles or other hollow glass ware by means of an improved
arrangement and combination of the tables carrying the parison moulds and the
table or tables carrying the blowing moulds. According to my present invention
I form a table of radial or other approved shape to carry say two blowing moulds
one over a hole in right side the other over a hole in left side of table.
this table I arrange two revolving tables, the one on the right hand the other on
the left, each of which revolving tables carries, say six parison moulds. The six
parison moulds in the right hand revolving table are so arranged that each move-
ment of this revolving table brings one of these parison moulds under the right
hand blowing mould in the fixed radial table and each movement of the left hand
revolving table brings a parison mould under the left hand blowing mould of this
fixed table. Over each hole in the fixed table I fix the outer or blowing mould
and above this I support in any suitable manner the arrangements for plunging
and for blowing the bottle or other hollow glass ware. In some cases where such
bottle or other hollow glass ware is very long I apply a plunger so shaped that
the stem carrying the plunger is smaller than the plunger and this stem works
through a collar large enough to keep the plunger perfectly steady and a pressure
of air is kept up behind this plunger so as to keep the hollow glass ware, being
plunged, perfectly true. It will be well understood that the plunging and blowing
arrangement is fixed over each mould and a further improvement which my present
invention contemplates is the doing both the pressing & the blowing by the one
plunger and the holding of the blowing mould in a securely closed position by a
screw arrangement which screw arrangement is fitted on the outside of the blowing
mould and is twisted thereon by the workman (before he commences to plunge the
parison) or by any suitable mechanical means. After he has plunged the parison
he lowers the parison mould and inserts mould bottom and whilst the blowing
mould still remains closed he sends a current of air through the space between the
slot in which the plunger works and the plunger itself and this blows the bottle
or other hollow glass ware out to its full size. In the making of very long tubing
I adopt a moveable bottom which moves downwards as the tube is being pressed
and which bottom is counterbalanced in any suitable manner. As the bottlemaker
is plunging and blowing a bottle in the right hand parison and blowing mould the
lader or gatherer is lading or gathering into the left hand parison mould another
quantity of molten glass sufficient for forming another bottle and by the time the
lader has got this laded in another of the parison moulds on the right hand side
will again be ready for receiving the molten glass and thus a continuous system of
lading and blowing is kept up by the two workmen instead of there being as now
a period when the lader is waiting for the presser and blower or the presser and
blower is waiting to get the parison into proper position.
The two revolving tables carrying the parison moulds may be actuated either by
hand or by steam power or by other mechanical means. Although prefer to
work in the proportion of one blowing mould to six parison moulds I would have
it well understood that I do not limit myself to this exact quantity or proportion.
The parison moulds may be propelled up into the blowing moulds or withdrawn

page_text: therefrom either by hand levers or by hydraulic arrangement or by a combination
of pneumatic and hydraulic or by any other suitable means.
It will be well understood that the plunger will be withdrawn or partially, with-
drawn from the parison before the blowing process commencer. Also that the
arrangement of two revolving parison tables under one fixed finishing table may
be applied to pressed glass ware. Also that where practical or so preferred the
blowing moulds may travel and the parison moulds be stationary. Also that the
molten glass may be run into the parison moulds by a syphon or other suitable
arrangement.

Improvements in or applicable to Machinery for the Manufacture

I, DAN RYLANDS of 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 has for its object improvements in machinery for the manufacture
of bottles or other hollow glass ware by means of an improved arrangement and
combination of the tables carrying the parison moulds and the tables carrying the
blowing moulds. My invention also relates to an arrangement of blowing apparatus
and to a method of admitting air under pressure to the interior of hollow glass
ware during the descent and ascent of the pressing pin or plunger.
Fig. 1 (Sheets 1 and 2) is a front elevation; Fig. 2 a side elevation; Fig. 3 a
plan view; and Fig. 4 a sectional elevation of an arrangement of mould designed
for the manufacture of hollow ware of exceptional length.
g
In Figs. 1, 2 and 3 a is the inner or parison mould, the outer or blowing mould
made in two parts and hinged together at c, d the pressing plunger operated by the
balanced lever e, f the mould cover threaded on to the tubular boss and provided
with handles, i an hydraulic cylinder and j the piston rod; k¹ (Fig. 3) parison
mould tables, blowing mould tables, m m the blowing mould bottoms carried
and guided by the levers n n', oo are cylindrical guides carried by and secured to
the parison mould tables and are for the purpose of guiding in an up and down
direction the parison moulds a a. The parison mould tables kk' are capable of an
intermittent revolving movement around the central fixed pillars p p after the
manner fully described and illustrated in Specification 16184 (1889).
The method of operating the above described machine is as follows:-Molten
metal being charged into parison mould a 1, carried by parison mould table k
(Fig. 3), the parison table is revolved until the charged parison mould arrives in
position a 2 immediately under and central with the pressing plunger d. The piston
rod of the hydraulic cylinder now elevates the parison mould into the interior of
the blowing mould as shown by Fig. 3; the operator now through lever e causes
the plunger to descend and complete the formation of the parison bottle. The
plunger next ascending and the parison mould descending will leave the parison jar
or bottle suspended by the mouth portion in the interior of the blowing mould.
The mould bottom m being next swung into position under and central with the
outer or blowing mould b, air under suitable pressure is slowly admitted through
piper ports s s into the interior of the parison causing it to gradually distend and
assume the formation of the interior of the blowing mould. Whilst the attendant
has been conducting the above described series of operations the ladler has charged
parison mould a 2 carried by parison table k¹ with metal, which the attendant now
proceeds to operate upon after the manner previously shown. This having been
accomplished the attendant proceeds to remove the finished jar or bottle which now

page_text: has had time to assume its completed form, from the outer mould b, which is accom-
plished by unscrewing and elevating the mould cover f away from and above the
upper surface of blowing mould, when the mould can be opened by the handles and
the finished article removed.
It will be seen that the ladler and the attendant operate upon the two parison
tables in succession and alternately, and that during the time that metal is being
charged to one table the pressing and other operations are going on at the other;
and that the time given for the full blowing and formation of a jar or bottle at one
table will be the time taken by the attendant in conducting the pressing and other
operations at the other table. Fig. 4 is a sectional elevation showing the method
of producing a tube or jar of exceptional length; a is the mould in two parts and
hinged together at b, c a movable balanced mould bottom, d the mould cover con-
structed after the manner previously shown, e the guided pressing plunger, the
air supply pipe and g g ports admitting air under pressure to the interior of the
pipe behind the pressing plunger. Metal being ladled or otherwise charged into
the mould a, and the mould being placed under the pressing plunger, the mould
cover is now screwed down into position.
The plunger next descending displaces the molten metal and forms the tube as
shown. During the descent of the plunger air pressure is admitted into the
interior of the tube causing it to set and retain the formation given to it by the
exterior diameter of plunger and the internal diameter of mould. The mould
bottom being loose in the mould and balanced by any suitable means will retreat
before the advancing plunger so that no undue pressure may be placed upon the
metal under operation. In the illustration the tube is shown formed with a solid
end, but it will be evident that if the plunger had continued its course and displaced
the movable bottom from the mould a tube open at both ends would have been the
result.
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. In bottle making machinery the combination of two revolving or fixed parison
tables working in conjunction with one or more fixed or revolving radial or other
shaped blowing tables as and for the purpose herein described.
2. The special arrangement hereinbefore described for blowing or forming glass
tubes or other large hollow glassware.
3. In combination with bottle-making machinery the arrangement of a collar
actuated by a screw or other suitable mechanical arrangement which collar works
on the outside of the blowing mould.
4. In a bottle making machine the special arrangement for blowing the air
between the plunger and the mould cover substantially as described and shown.
