PROVISIONAL SPECIFICATION.
Improvements in Moulds for Forming Bottles by the Pressing and
Blowing Process.
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:-
My Invention relates to.improvements in moulds used for producing machine-made
Bottles by the process of pressing and blowing, and refers especially to that process as
described in the Specification of the Patent Application made by me on the 3rd day of
March 1888 and numbersd 3263.
In this process the Bottle or other article is first partly formed by pressing in a
mould combined of an inner mould (wherein the body portion of the Bottle is partially
formed) and a portion of an outer mould forming, in combination with the presser,
the neck or mouth; the partially formed body of the Bottle being expanded by
blowing to its full size after the inner mould has been withdrawn; my present object
being to produce a Bottle, Jar, or other article, having two inclined projections formed
on the outside of the upper portion of the neck. In order to accomplish this I con-
struct a mould or moulds having indentations formed on the upper or neck portion of
the mould near the top, such indentations being of a similar shape as the two external
inclined projections that it is desired to produce.
Also to produce an external annular bulb or enlargement at any suitable distance
below these inclined projections, such annular bulb or enlargement being of such
external diameter as to be parallel with the outside of the cap which fits over such
projections. To accomplish this second process I cut in the mould neck an annular
indentation at any suitable distance below the indentations for the inclined projections,
such annular indentation being slightly deeper than the indentations for forming the
inclined projections.
Also for another class of Bottles to produce an annular bulb or enlargement at any
suitable distance below the aforesaid inclined projections of larger external diameter
than the outside diameter of the cap which fits over the inclined projections. To
accomplish this latter process I cut in the mould a still deeper annular indentation
than in the annular indentation last named.
I so form or arrange the mould that the pin, plug, or plunger (which is brought
down into the molten glass after such molten glass has been poured, laded, or run
into the inner mould) will in combination with the action of the inner mould force
the molten glass into the inclined indentations, and also into the annular indentations,
and immediately this is done I by means of the blowing process expand the partially
formed Bottle to the full size required, in the manner described in my aforesaid
Patent Specification No. 3263 A.D. 1888.

COMPLETE SPECIFICATION.
Improvements in Moulds for Forming Bottles by the Pressing and
Blowing Process.
I DAN RYLANDS of Hope Glass Works, Stairfoot, near Barnsley in the County of
York Glass Bottle Manufacture 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 improvements in Moulds used for producing machine made

page_text: Bottles by the process of pressing and blowing and refers especially to that process as
described in the Specification of the Patent Application made by me on the 3rd day
of March 1888 and numbered 3263.
In this process the Bottle or other article is first partly formed by pressing in a
mould combined of an inner mould (wherein the body portion of the Bottle is partially
formed) and a portion of an outer mould forming in combination with the presser the
neck or mouth the partially formed body of the Bottle being expanded by blowing to
its full size after the inner mould has been withdrawn my present object being to
produce by machinery a Bottle, Jar or other article having two or more inclined pro-
jections of any suitable shape formed on the outside of the upper portion of the neck,
and to produce an external annular bulb or enlargement at any suitable distance
below these inclined projections, such annular bulb or enlargement being of such
external diameter as to be about parallel with the outside of the cap which fits over
such projections, and thus provent dust or dirt collecting on the hollow underside of
cap To accomplish this I cut in the Machine mould neck at any suitable distance
below the inclined indentations an annular indentation which is just the depth for
securing a neat annular ledge for bottom of tin cap to rest upon and be flush or level
with the outer edge thereof.
Also for another class of bottles to produce an annular bulb or enlargement at any
suitable distance below the aforesaid inclined projections of larger external diameter
than the outside diameter of the cap which fits over the inclined projections, and thus
1 succeed in providing a bottle having a suitable ledge or flange (below the inclined
projections) for forming an airtight joint during the filling process by means of the
nozzle of a filling machine and yet allowing of the bore of the barrel over such
nozzle being sufficiently wide to allow of the metal cap for closing the bottle being
easily passed down the inside of such barrel and of the cap being adjusted in airtight
position before the airtight joint formed on such ledge need be broken.
To accomplish this I cut in the mould a still deeper annular indentation for forming
such a ledge or flange as will adapt the bottle to the particular filling Machine which
the user desires to adopt-I would have it understood that any suitable kind or
number of inclined projections may by invention be formed on the outside of bottle-
mouth or neck and any width of annular ledge or flange it being clear that a screw
or other shape of inclined projection may be adopted without departing from the
principle I here describe, and also that the width of the annular flange or ledge may
be varied to suit the class of filling-machine the user adopts.
I so form or arrange the mould that the pin, plug or plunger (which is brought
down into the molten glass after such molten glass has been poured, laded or run
into the inner mould) will in combination with. the action of the inner mould force
the molten glass into the inclined indentations, and also into the annular indentations
and immediately this is done I by means of the blowing process expand the partially
formed bottle to the full size required in the manner described in my aforesaid
Patent Specification No. 3263 A.D. 1888.
In the accompanying Drawing in which fig. 1. is a sectional elevation showing
combined bottle mould, fig. 2, a sectional view of bottle mouth, fig. 3 being a plan
view of same, and fig. 4 an elevation of bottle mouth.
Referring to fig. 1 a. is the inner mould b. a portion of an outer mould, c, a
pressing Pin or Plunger, d. the lower portion of blowing mould, e. the mould
bottom. The method of operating the above named parts being fully set forth and
illustrated in the specification No. 3263, 1888.
In fig. 1, ff, are the inclined indentations formed on the interior of the Neck
and 9. g. the annular indentations, and which indentations in conjunction with the
pressing pin, produce the inclined projections h, h, and annular enlargement or
flange i. i, as shown by figs. 2. 3. 4.
The annular enlargement or flange may be of smaller or larger diameter to suit
the cap that may be required.

page_text: 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 a Machine for manufacturing bottles by the pressing and blowing process the
combination of such inclined and annular indentations as will secure such a formation
on the outside of the necks or mouths of the bottles or jars as to prevent and for
the purpose of preventing dust accumulating on the underside of the cap or
stopper.
2. In a Machine for manufacturing bottles by the pressing and blowing process the
combination of such inclined and annular indentations as will secure such a formation
of the outside of the mouths or necks of the bottles as to adapt them for being filled
by a Filling Machine where the nozzle of Filling Machine has to form an airtight
joint on annular flange or ledge on outside bottle mouth or neck in such a way as to
allow of the closing cap being secured in airtight position whilst nozzle of Filling
Machine forms airtight joint on such annular flange or ledge.
