Improvements in Machinery for the Manufacture of Bottles and
other Glass Ware, and in the Processes of Working the
same.
I, DAN RYLANDS, of Stairfoot, Barnsley, in the County of York, Glass
Bottle Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My present invention has for its object the better regulation of the pressure of
the punch or plunger used in first pressing the molten glass into the required shape
for blowing out the bottle or other glass ware to its full size.
Also the improvement of arrangements of parts or process in order to secure
that the inner or pressing or parison mould or moulds shall be kept at the heat most
favourable for securing the best output of bottles or glassware.
According to the first part of my present invention I so arrange the bottom of
the inner or parison or pressing mould that said bottom can be moved or lifted any
suitable height up the said inner mould and preferably to such a height that when
the shoulders (that is the neck and cuth-forming portion) of the outer or blowing
mould are closed the molten glass will before being pressed be within about half
an inch of the top of said shoulders.
By any suitable arrangement (such as springs or air pressure or weighted lever)
connected with or under or attached to the said movable bottom secure just
sufficient counterpoise to allow of the molten metal which is poured, run, or placed
into the mould being so supported against the pressure of the plunger as to only
allow of enough pressure being exerted on the molten glass as will correctly and
properly form the bottle mouth and neck or the required top portion of other
glassware and so that immediately this has been done the movable bottom of
parisou mould and also the parison mould itself descends to the proper position for
allowing the bottle or other glassware to be fully blown in the blowing mould the
said parison mould being withdrawn either simultaneously with or instantly after
the withdrawal of the said bottom. In some cases I utilize the movable bottom of
parison mould in helping to form the bottom of blowing mould. Or where preferred
the separate bottom of blowing mould may be passed in through a suitable opening
at bottom thereof. In either case a proper arrangement is made for holding either
bottom in the proper position for securing a well blown bottle.
In order to insure the keeping of the inner or parison or pressing mould or moulds
at the most favourable heat for successful working I so arrange the outer or blowing
mould or the shoulders thereof that one outer or blowing mould is worked
alternately over two or more inner or parison moulds.
Or where preferred each parison inould may be lowered through a cold water
jacket or a current of cold air may be passed into or upon each parison mould
whilst lowered clear of the blowing mould.
I wish it to be well understood that my present improvements can be applied to
either fixed, or rotary or radial machines for the manufacture of bottles or other
glassware and also that in some cases it may be possible to have the parison mould
with solid bottom instead of with movable bottom and to work same mouth or top
downwards as well as upwards without departing from the scope of my present
invention.

Improvements in Machinery for the Manufacture of Bottles and
other Glass Ware, and in the Processes of Working the
same.
I, DAN RYLANDS, of Stairfoot, Barnsley, in the County of York. (ilass
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 present invention has for its object the better regulation of the pressure of
the punch or plunger ne in first pressing the molten glass into the required shape
for blowing out the bottle or other glass ware to its full size. Also the improves
ment of arrangements of parts or process in order to secure that the inner or
pressing or parison mould or moulds shall be kept at the heat most favourable for
securing the best output of battles or glassware. According to the first part of
my present invention 1 so arrange the bottom of the inner or parison or pressing
nould that said bottom can be moved or lifted any suitable height up the said inner
mould and preferably, to such a height that when the shoulders (that is the neck
and mouth-forming portion of the outer or blowing mould are closed the molten
glass, will before pressed, be within about half an inch of the top of said shoulders,
By any suitable arrangement (such as springs or air pressure or weighted lever)
connected with or under or attached to the said movable bottom. I secure just
sufficient counterpoise to allow of the molten metal which is poured run or placed
into the mould, being so supported against the pressure of the plunger as to only
allow of enough pressure being exerted on the molten glass as will correctly and
properly form the bottle mouth and neck or the required top portion of other
glassware and so that immediately this has been done the movable bottom of
parison mould and also the parison mould itself, descends to the proper position for
allowing the bottle or other glassware to be fully blown in the blowing mould, the
said parison mould being withdrawn either simultaneously with or instantly after
the withdrawal of the said bottom. In some cases I utilize the movable bottom of
parison mould in helping to form the bottom of blowing mould. Or where preferred
the separate bottom of blowing mould may be passed in through a suitable opening
at bottom thereof. In either case a proper arrangement is made for holding either
bottan in the proper position for securing a well blown bottle,
In order to insure the keeping of the inner or parison or pressing mould or
moulds at the most favourable heat for successful working. I so arrange the outer
or blowing mould or the shoulders thereof that one outer or blowing mould is
worked alternately over two or more inner or parison moulds,
Or where preferred each parison mould may he lowered through a cold water
jacket or a current of cold air may be passed into or upon each parison mould
whilst lowered clear of the blowing mould,
I wish it to be well understood that my present improvements can be applied to
either fixed, or rotary, or radial machines for the manufacture of bottles or other
glassware, and also that in some cases it may be possible to have the parison mould
with solid bottom instead of with movable bottoni and to work same mouth or top
downwards as well as upwards without departing from the scope of my present
invention.
The nature of this invention and the manner of carrying it into effect will be
readily understood on reference to the three sheets of drawings herennto annexed
and the following explanation thereof.
Fig. 1 is an elevation partly in section; Figs. 2, 3 and 4 are sectional elevations ;
and Figs. 5, 6 and 7 are plan views of mould and mould table.
In Figs. 1, 2, 3, and 4, a is the movable bottom of the parison or pressing
mould is the blowing mould in two halves, which are hinged together at d, and
secured and held together by the catch lever ; is a pillar on which the two

page_text: P
halves of the blowing mould c are carried and on which as a centre they are free
to open and shut; g is the blowing mould bottom carried and guided by the
carriage h; ii are guides between which the carriage h is free to travel between
the positions shown by Figs. 2 and 4; j is a handle for operating the carriage h;
k is a movable table secured to the pillar l; m a bracket arm secured to and carried
The
by lower end of pressing mould forming a fulcrum for the balance lever n.
lower end of movable parison mould bottom is formed with a slot o in which is free
to work the bowl carried by end of balance lever ; q is a guide rectangular in
section secured at its upper end to the bracket m, the lower end being free to work
through the guide plate r; s is a connecting link connecting the pressing mould 6 to
lever t; w is a fulcrum pin to which the levers and are secured; y a detent lever
fulcrummed at z and capable of engaging with the collared stud a1 carried by
lever; 2 is a detent lever carried by stud a 3 for the purpose of securing the
movable mould bottom in the position shown by Figs. 1 and 3; a4 is a bracketed
arm carried by pillar and formed at a5 is a tubular guide through which the
pressing ram 6 is free to work; a7 is a balanced pressing lever and a8 a con-
necting link connecting the pressing lever with the cross head a 9 carried by the
upper end of the pressing ram a 6 a 10 is the pressing plunger.
The method of operating the above described apparatus is as follows: The
blowing mould c being closed and locked by the catch lever e the parison mould b
and the movable parison mould bottom a being in the position shown by Fig. 2,
molten metal is charged into the cavity contained in the upper portion of the
pressing and blowing moulds; the pressing plunger descending causes the molten
metal to ascend and occupy the space formed in the upper portion of blowing
mould thus completing the neck and mouth of the bottle or other article. The
plunger in its descent having closed the opening in upper portion of blowing
mould will cause the descent of the movable mould bottom which will then
occupy the position shown by Fig. 3, when the detent lever a 2 will have latched
itself on to stud a 11 thus preventing the ascent of the movable mould bottom
upon the reascent of the pressing plunger. The sliding pressing mould being
now by levers and links withdrawn from the blowing mould, the blowing mould
bottom being now under and central with the blowing mould, the parison mould is
again raised lifting the blowing mould bottom into the position shown by Fig. 4,
a blowing attachment such as described in my previous Patents (not shown in the
drawings) carried by pressing ram now descending closes the mouth of the blowing
mould. Air under pressure being then admitted will cause the parison as shown
by Fig. 3 to expand and assume the completed form as in Fig. 4.
It will be seen that the counterpoised pressing mould bottom will prevent any
undue pressure being applied by the plunger to the molten metal and as a con-
sequence the bottles or other articles will be free from marks or other defects ;-
also that the molten metal being charged into the upper portion of the combined
mould the metal will not have far to ascend before the neck and mouth portion of
the bottle is formed -and that the after formation will be from the top down-
wards thus preventing any violent plunger action on the molten metal. To ensure
the blowing mould being of sufficient and suitable heat, any convenient number of
parison or pressing moulds are employed shown by Fig. 6 in plan view the movable
plate with the blowing mould and the blowing mould bottom being capable of
being moved radially around the pillar-and over the upper surface of the pressing
or parison moulds.
Fig. 7 shows a modification of the above-described arrangement. The table k
and blowing mould c being stationary and secured to and carried by central
pillar, the parison moulds and movable parison mould bottoms, with their actuating
apparatus being carried by the circular table a 13, to which an intermittent
revolving movement is given as described in a previous Patent. The drawings
show the movable pressing mould bottom balanced by counterweight but it will
be evident that the same object may be attained by springs or other equivalents.

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 the manufacture of machine-made bottles the process of regulating, by
means of suitably counterbalanced parison mould bottoms or parison moulds, the
pressure exerted on the molten glass during the plunging or pressing of the
parison.
2. In the manufacture of machine-made bottles the adaptation or arrangement
of parts securing that one blowing mould (whether fixed or capable of being rotated
or moved can be worked in conjunction with two or more parison moulds
substantially as shown and described with reference to Figures 6 & 7 or any
mere modification thereof.
3. The special arrangement and combination of mechanical parts as shown in
Figures 1 to 7 of the accompanying drawings constituting improvements in
machinery for the manufacture of bottles and other glass ware.
