PROVISIONAL SPECIFICATION.
Improved Means of Forming and Closing the Mouths of Bottles
or Jars.
I, DAN RYLANDS of Hope Glass Works, Barnsley in the County of York, Glass
Bottle Manufacturer, do hereby declare the nature of this invention to be as
follows-
According to my present invention I form the mouths of bottles or jars by means
of the machine for which Letters Patent have been granted to me such Letters Patent
being numbered 3263 A.D. 1888. But in order to better adapt such machine for
my present invention cut or form in the top part of such machine that is in that
part where the mouth of the bottle is formed first an annular indentation for forming
rim on the outside of the mouth of such bottle. This annular indentation is formed
so as to produce this annular rim preferably within about th inch of the top of the
bottle mouth. Immediately below and if so desired running into the underside of
this annular indentation in the mould I cut either a suitable screw thread or two or
more suitable inclined indentations so as to produce on the outside of the bottle
mouth either a male screw thread of sufficient length or two or more raised inclined
projections. Below such thread or projections there may be formed another annular
outside rim on the bottle mouth. I then make or form a hollow cap of tin or other
suitable metal or material. Around the inside of the top portion of this cap I form
an annular groove for receiving a ring made of india rubber or other suitable
substance. After placing such ring in such annular groove I insert in the centre
of this ring a cork disc of such a size that it will cover the mouth of the bottle
and impinge on the top of such mouth all round. Thus whilst the cork disc is
pressed on the top outside of bottle month the india rubber washer forms an airtight
joint by pressing on the outside rim on the outside of mouth of bottle above such
rim formed as before described. Below the annular groove on the inside of the cap I
form either suitable screw threads or suitable indents or projections to work on the
screw threads or projections formed on the outside of the mouth of the bottle, thus
by this means to screw down and hold down the stopper in air tight position.

Improved Means of Forming and Closing the Mouths of Bottles
or Jars.
I, DAN RYLANDS of Hope Glass Works, Barusley, 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:-
I form the mouths of bottles or jars by means of the machine for which Letters
Patent have been granted to me, such Letters Patent being numbered 3263, 1888.
By reference to the accompanying sheet of drawings (Fig. 1) it will be seen that, in
order to better adapt such machine to my present invention, I cut in that part of the
mould where the mouth of the bottle is formed, an annular indentation A, for the
purpose of forming a rim A' (Figs. 2, 3, 4, 5 and 6) on the outside of the mouth of
such bottle or jar preferably within an inch of bottle mouth. Immediately below
(and if desired running into) the underside of this annular indentation in the mould
I cut or form either a suitable screwthread or two or more suitably inclined indenta-
tions of proper length B and so produce on the outside of the bottle mouth, either a

page_text: male screw thread B or two or more raised and inclined projections B (Fig. 4).
Below such thread or projections and formed by, the annular groove in mould C
(Fig. 1) there may be another circular outside rim C₁ (Figs. 3 and 6) on the neck
of bottle or jar.
I then make or form a hollow cap or cover K of tin or other suitable material
in one or more parts. Around the inside of the top portion of this cap I form a
slightly undercut recess to receive a ring of india-rubber E or other suitable
substance. After placing the rubber ring in position I insert in the centre of the
said ring a cork disc F of such a size that it will cover the mouth of the bottle and
also impinge on the top of rim A'. Thus whilst the cork dise is pressed on the
rim A, the rubber washer E forms an airtight joint by pressing on the outerside of
top part of bottle mouth or upon a portion of the said rim A
In the sides of the cap or cover K I form either, screw threads H or indenta
tions or projections H₁, to work in or under the screw threads B or projections B²,
on the outside of the mouth of bottle or jar and thus screwing down and securing
the cap or cover of bottle or jar perfectly airtight.
Fig. shews the portion of machine where the mouth of bottle is formed in
accordance with this invention.
Fig. 2 shews cap separate and in position.
Fig. 3 is a modification of the same and shows the lower annular ring.
Fig. 4 illustrates the mode of applying the indentations in cap and also inclined
projections on bottle neck.
Fig. 5 shows the cap in two parts with india rubber ring and cork disc in position
separate and also on bottle or jar.
Where so preferred the top part K' may be made of tinned lead or other soft
metal and in this case it is not necessary to use the cork disc F, and also the india
rubber ring E instead of being fixed in the top K is attached round the bottle neck.
The top part of the screwed portion of cap K is brought tightly down upon this soft
metal top thus causing it to impinge so firmly on the rubber washer E as to form an
air-tight joint, at the same time the top K is so shaped that it presses upon the
top A. Where it is required to boil the contents of the jar after this top K₁ of
soft metal has been placed on a small vent hole is left in the centre of the said top
which vent hole, immediately the contents of the jar have been properly cooked, can
be closed up by a pair of tweezers or other suitable tools.
Fig. 6 is a modification of same applied to a long neck bottle such as beer and wine
bottle.
The same letters of reference apply to all the figures or illustrations.
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
First. The manufacture, by machinery, of bottles having mouths as shown in
Fig. 1 of the accompanying drawings.
Second. The cap as shown in Fig. 2, wherein the india rubber ring E rests in the
recess D, having in the centre of it a cork dise: Fas and for the purposes described.
Third. The special combination of parts as shown in Figs. 3. 4, 5 and 6.
Dated this 8th day of May 1890.
