PROVISIONAL SPECIFICATION.
Improvements in or applicable to Bottle-making Machinery.
We, DAN RYLANDS of Hope Glass Works, Stairfoot near Barnsley, in the
County of York, Glass Bottle Manufacturer, and BENJAMIN STONER of Stair-
foot aforesaid, Mechanical Engineer do hereby declare the nature of this invention
to be as follows:-
Our present invention has for its object improvements in bottle-making machines
by an altered arrangement of the number and node of working of the inner or
parison moulds. According to our present invention we form a circular or other
suitably shaped table which carries any suitable number of inner moulds. One
important point in our present invention being that there shall be a larger number
of inner moulds than there are of outer moulds and that the inner moulds shall
work independently of the outer moulds except at such times that the inner mould
is lifted up in order that the molten glass be pressed or shaped into, what is
technically known, as the parison shape. In some cases the inner moulds would be
as two to one to the outer moulds and the number will vary according to the class
and shape of these moulds. The table carrying the inner moulds is made to revolve
or work underneath the table carrying the outer or blowing mould. The inner
inould table is so arranged that as soon as the molten glass has been poured or run
into one of the inner moulds this inner mould is revolved or passed under the
pressing plunger of the bottle-making machine and when in this position it is lifted
up by any suitable mechanism so that the top of the inner mould fits tightly against
the shoulder or neck of the outer mould. The plunger on the bottle machine is
then brought down forcing the molten glass up into the mouth of the outer mould
where it is held until the parison or inner mould is withdrawn. During the time
that this plunger has been going forward another inner mould (which has been filled
with another charge of molten glass, and immediately the first has been moved
beyond the position for pressing) is brought into the position for pressing when the
process, as previously herein described is again repeated though with the next
blowing mould. In this way each parison mould is worked round into position
under the pressing mould and as each parison mould passes or revolves away again
when empty it has an opportunity of cooling. We so arrange the table carrying
the parison moulds that it will work into exact position under the plunger and for
working with the blowing moulds but so that if we have eight inner moulds on the
table which revolves under the bottle-making machine and four blowing moulds
on the bottle-making machine the eight moulds on the inner mould machine
will work true with the four outer moulds on the bottle-making machine but
so that each outer mould. will be used twice to each inner mould being used
once. Though we have mentioned the proportion of eight inner moulds to
four outer moulds we wish it to be distinctly understood that we do not limit
ourselves to this exact number only that the number of inner moulds inust be larger
than the number of outer moulds. Instead of moving or revolving the parison
moulds it may be preferable, in some cases, to move the blowing mould and to move
the pressing arm and the blower instead of those remaining fixed over the revolving
machine. The arrangements we have herein-before described are applicable to
rotary machines worked by steam power and it will be well understood that, both
the table carrying the outer or blowing mould and the table. carrying the inner or
pressing mould, in this case will both revolve but at different speeds and the usual
arrangement for blowing the bottle from the parison will be necessary before the
bottle can be completed. We would have it well understood that our present
arrangement of parison moulds is equally applicable to hand machines but in this

page_text: case it may be preferable to only use two or three parison moulds to one blowing
mould and the most suitable form for working would be to have the parison moulds
fixed and the blowing moulds moveable.
We would have it clearly understood that we do not limit ourselves to shape of
table which carries either inner or pressing moulds or outer or blowing moulds nor
to movement of such table nor to the arrangements for blowing the bottle or jar or
other article.

COMPLETE SPECIFICATION.
Improvements in or applicable to Bottle-making Machinery.
We, DAN RYLANDS of Hope Glass Works, Stairfoot near Barnsley, in the
County of York, Glass Bottle Manufacturer and BENJAMIN STONER of Stair-
foot aforesaid, Mechanical Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
Our invention has for its object improvements in bottle making machines by an
altered arrangement of the number and method of working of the inner or parison
moulds and is in some respects a modification and addition to the machine described
and illustrated by Specification No. 16184 (1889).
In order that our invention may be clearly understood we append hereto, two.
sheets of drawings in which
Fig. is a side elevation and Fig. 2 a plan view.
In Figs. 1 and 2 a is a circular outer mould table capable of rotation around the
vertical central fixed pillar b; C C are outer or blowing moulds carried by
brackets dd; e a circular inner mould table the shaft f of which is guided and
carried by pillar; h h are inner moulds guided in an up and down direction by
the cylindrical bushes ii; j a cylinder the piston rod of which carries at its
upper end a crosshead ; m, m, are headed attachments screwed into lower portion
of inner moulds; n, u, ratchet wheels secured to the bosses of the outer mould and
inner mould table respectively; o a crank; and p p crank plates united together by
crank pinq; connecting rods; 8 8 ratchet wheel levers; tt pawls; w, a vertical
crank shaft so actuated that after it has made one complete revolution it will with
its cranks connecting rods, ratchet levers, and pawls come to rest in the position
shown by Fig. 2.
The method of operating the above described inner and outer mould tables with
their accompanying inner and outer moulds is as follows:-Molten metal being
charged into the cavity contained in the upper portion of inner mould h¹; the crank
shaft wis set in motion giving movement to the connecting rods pawls &c., and
causing the rotation of the inner and outer mould tables so that the inner mould ¹
will now occupy the position h2 and the outer mould c will have arrived at position c¹,
the charged inner mould h² being now under and central with the outer mould ci
and the headed attachment m having become connected with the crosshead l. The
piston rod know elevates the charged inner mould into the interior of outer mould c¹
as shown by Fig. 1. The pressing plunger descending completes the formation of
the parison jar or bottle. This having been accomplished the piston lowers the
empty inner mould away from the outer mould leaving the parison suspended by
the mouth portion in the interior of the outer mould. The inner and outer mould
tables being again rotated will cause the next succeeding inner and outer moulds to
arrive in the pressing position when the previously-described pressing and parison
mould elevating and lowering operations will be repeated.
. After the formation of the parison jar or bottle, the outer mould containing the
parison will on further rotation of the outer mould table arrive under the blowing

page_text: apparatus which is of similar construction to the one described in Specification
No. 16184, 1889 when the parison will by air pressure be expanded and caused to
fill and fit the outer mould, thus completing the formation of the finished jar or
other article.
Any convenient number of inner and outer moulds may be employed but we
prefer to have a larger number of inner than outer moulds.
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:-
In bottlemaking machinery arrangements for combining, with the table which
carries the outer or blowing moulds, a separate table of circular or other suitable
shape carrying inner or pressing moulds, one form of such arrangement being shown
and described with reference to Figs. 1 & 2 of the accompanying drawings.
2. In bottlemaking machinery arrangements for using a larger number of inner
or pressing moulds than of outer or blowing moulds as shown and described with
reference to Figs. 1 & 2 of the accompanying drawings.
