Bottles and Glass Jars and other like Glass Articles.
I JAMES RICHARD WINDMILL of Collis Street Dennis Park near Brierley Hill in
the County of Stafford Commercial Traveller do hereby declare the nature of this
Invention to be as follows:-
My invention consists in manufacturing glass bottles and glass jars and other like
glass articles by the combination of the processes of pressing and blowing as hereinafter
described. My invention consists further of the apparatus hereinafter described to
be used in conducting the said pressing and blowing processes. I will describe my
invention as applied to the manufacture of glass jars in conjunction with the
apparatus which I prefer to use.
The apparatus consists essentially of a sliding mould in which the pressing of the
glass article is effected and a second or outer mould surrounding the sliding mould
in which second mould the pressed article is blown and the required form given to
it. The sliding pressing mould consists of a cylinder having a cavity or mould of
the required shape made in it the said sliding mould working through an opening
in the base plate of the apparatus. The rising and falling motion of the sliding
mould is effected by a lever the said mould when raised within the blowing mould
being held in that position by a spring catch engaging with the lever of the sliding
mould. On the base of the apparatus the blowing mould is supported the said
nould being divided vertically into two halves hinged together at back the said
halves when closed being held together by a catch. Jointed to an upright at one
side of the base plate of the apparatus is a cover by which the compound mould is
closed the said cover being held down by a spring catch. Through this cover a
pressing plunger for operating upon the melted glass in the pressing mould works
the said plunger being jointed to a lever and the latter to a link connected to the
upright to which the cover is jointed. A coiled spring between the plunger lever
and the cover described raises the said plunger from the mould. The top of the
blowing mould is provided with a neck or contraction in which the neck of the glass

page_text: article being made is formed. When the article is being blown in the outer mould
the said mould is closed air tight by a conical cap or cover on the end of the blow
pipe the said cap or cover fitting in the open end of the mould and top of the article
and accurately closing them.
In making a glass jar according to my invention I proceed as follows:-The
sliding pressing mould is raised into the outer blowing mould and supported in
its raised position. The halves of the blowing mould are closed and fastened together.
The melted glass being placed in the pressing mould the cover and plunger are
brought down and the former fastened in its place. By operating the plunger by its
lever the melted glass is pressed and fashioned in the mould a portion of the glass
being forced into the neck of the outer or blowing mould. The cover and plunger
being raised and turned back the sliding mould is depressed through the base plate
leaving the pressed glass article attached by its neck to the neck of the blowing
mould. The opening in the base plate through which the sliding mould is withdrawn
having been closed by a slide or sliding plate the cap or cover of the blow pipe is
fitted into the top of the blowing mould and article and the pressed article is now
blown in the said mould in the ordinary way of blowing glass articles. In this
manner the melted glass is first pressed into a roughly formed jar and the pressed
jar afterwards completed by blowing it in a second mould.
Instead of closing the opening in the base plate as described the blowing mould
may be turned to a part of the base plate having no hole in it the said part of the
base plate constituting in that case the bottom of the blowing mould.

Bottles and Glass Jars and other like Glass Articles.
I JAMES RICHARD WINDMILL of Collis Street, Dennis Park near Brierley Hill in
the County of Stafford, Commercial Traveller, do hereby declare the nature of my
Invention and the manner in which the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention consists in manufacturing glass bottles and glass jars and other like
glass articles by the combination of the processes of pressing and blowing as herein-
after described. My invention consists further of the apparatus hereinafter described
to be used in conducting the said pressing and blowing processes.
I will describe my invention as applied to the manufacture of glass jars and glass
bottles in conjunction with the apparatus which I prefer to use.
The apparatus consists essentially of a sliding mould in which the pressing of the
glass article is effected and a second or outer mould surrounding the sliding mould in
which second mould the pressed article is blown and the required form given to it.
The sliding pressing mould consists of a cylinder having a cavity or mould of the
required shape made in it the said sliding mould working through an opening in the
base plate of the apparatus. The rising and falling motion of the sliding mould is
effected by a lever the said mould when raised within the blowing mould being held
in that position by a catch engaging with the lever of the sliding mould. On the base
of the apparatus the blowing mould is supported the said mould being divided vertically
into two halves hinged together at back the said halves when closed being held together
by a catch. Jointed to an upright at one side of the base plate of the apparatus is a
cover by which the compound mould is closed, the said cover being held down by a
catch. Through this cover a pressing plunger for operating upon the melted glass in
the pressing mould works, the said plunger being jointed to a lever and the latter to a
link connected to the upright to which the cover is jointed. A coiled spring between
the plunger lever and the cover described raises the said plunger from the mould.
The top of the blowing mould is provided with a neck or contraction in which the neck
of the glass article being made is formed.
When the article is being blown in the outer mould the said mould is closed air
tight by a conical cap or cover on the end of the blowing pipe, the said cap or cover
fitting in the open end of the mould and top of the article and accurately closing them.
Instead of combining the pressing mould and the blowing mould in the same apparatus,
the two moulds may be used apart substantially in the manner described for the
pressing and blowing operations..
The glass jar or glass article to be made is first pressed into a roughly formed article
in the pressing mould and its shape is perfected and finished by blowing it in the
second or blowing mould.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figure 1 represents in side elevation apparatus constructed according to my
invention for the manufacture of a glass jar or bottle according to my method, the
said apparatus having combined in it the sliding pressing mould and the jointed or
hinged blowing mould and Figure 2 represents that part of the apparatus which is
combined with the apparatus Figure 1 during the blowing or finishing stage of the
glass jar or bottle as herein after described.

page_text: a is the pressing mould capable of a sliding motion and b is the second or outer
mould made in two parts hinged together at back. The blowing mould 6 is supported
on the base plate c the sliding pressing mould a working through an opening in the
said base plate c. In Figure 1 the sliding pressing mould a is represented in its raised
position and the blowing mould b is represented closed. The said blowing mould b is
furnished at top with the neck or contraction 62 in which the neck of the glass jar or
bottle is formed and the said blowing mould is opened and closed by means of handles,
not represented, and when closed the two parts are fastened together by a catch. The
rising and falling motion of the sliding pressing mould a is effected by the lever d, the
said mould a being supported in its raised position within the blowing mould b by the
catch e engaging with the lever d of the sliding mould as represented in Figure 1;
h is the cover by which the combined mould a, b is closed the said cover being jointed
at h² to the upright g. The cover h when lowered is held down by the catch i engaging
in the depression h³ in the handle part of the cover; k is the pressing plunger for
operating upon the melted glass in the pressing mould a the said plunger working
through the hinged cover h. The plunger k is jointed at 2 to the lever and the
latter to a link m jointed to the upright g. By means of the coiled spring n between
the lever hand plunger lever the said plunger k is raised from the mould a; 8 is
a slide or sliding plate for closing the opening in the base plate c after the pressing
mould a has been depressed and the blowing mould b is about to be used. Or the
closing of the opening in the base plate c may be effected by turning the blowing
mould b to a part of the base plate having no hole in it the said part of the base plate in
that case constituting the bottom of the blowing mould b; p, Figure 2, is the conical
cap or cover on the blowing pipe q which cap and blowing pipe are used when the
article is being blown in the mould b. The cap or cover p fits in the open end of
the mould b and top of the article and accurately closes them.
In making a glass jar according to my invention I proceed as follows:-The
sliding pressing mould a is raised into the outer blowing mould b by the hand lever d
and the said mould a is supported in its raised position by the catch e engaging
with the hand lever d as represented. The halves of the blowing mould bare next
closed by their handles and fastened together by the catch. The melted glass being
placed in the pressing mould a the cover and plunger h, k are brought down and
the said cover fastened in its place by the catch i. By operating the plunger k by
its lever the melted glass is pressed and fashioned in the mould a a portion of the
glass being forced into the neck 62 of the outer or blowing mould 6. The cover
and plunger being raised and thrown back, the sliding mould a is depressed
through the base plate c leaving the pressed glass article attached by its
neck to the neck. 62 of the blowing mould b. The opening in the base plate c
through which the sliding mould is withdrawn having been closed by the slide
or sliding plate 8, or the mould b turned onto an unperforated part of the base 4
plate c, the cap or cover p Figure 2 of the blowing pipe 9 is fitted into the top of
the blowing mould b and article and the pressed article is now blown in the said
mould in the ordinary way of blowing glass articles. The cover p being removed
and the blowing mould opened upon its hinge the glass jar or bottle is removed and
the operations described are repeated. In this manner the melted glass is first 4
pressed into a roughly formed jar or bottle and the pressed jar or bottle afterwards
completed by blowing it in a second mould.
The apparatus which I employ when the pressing and blowing operations are
conducted by the use of a detached pressing mould and a detached blowing inould
is represented in Figures 3 and 4. Figure 3 representing in section the apparatus 5
used for the pressing operation and Figure 4-representing in section the apparatus
used for the blowing operation. The apparatus represented in Figures 3 and 4 is
suitable for the manufacture-of-glass bottles, the partly made bottle pressed in the
apparatus-Figure 3-being represented in Figure 5 and the finished bottle-blown in
the apparatus Figure 4 being represented in Figure 6.
a Figure & is the body of the separate pressing mould fixed to a bed plate and
is the plunger worked by a lever or in any other convenient way; h is the cover

page_text: of the pressing mould a jointed at h³ to the side a² of the mould a the plunger k-
passing through and fitting closely in a hole in the said cover. The said cover h
when depressed by the handle ³ is fastened down by the lever catch h.-The-top
and neck part of the mould is formed of the separable shoulders or half rings a³, a³
and the underside of the cover h. The said separable shoulders a³, a³ are common
to the pressing mould a, Figure 3, and the blowing mould b, Figure 4, as hereinafter
explained. The shoulders a³, a² are jointed or hinged together at back by the hinge
joint at a (see Figure 4) and are opened and closed by handles on the two parts
of the shoulders. The unjointed ends of the shoulders a³; a³ of the mould overlap
and the overlapping parts when the shoulders have been closed are fastened together
by the fixing pins a Figure 4; q is the blowing pipe having at its end the cap or
cover-p for closing the opening in the blowing mould 6-and-neck of the partly
made glass bottle (see Figure 4).
In making a glass-bottle of the kind represented in Figure 6 by my method of
manufacture and by the use of the apparatus represented-in-Figures 3 and 4, the
melted glass is placed in the pressing mould a Figure 3 which is then closed by depressing
and fastening down the cover h and the neck part of the mould-formed by the closing
and fastening together of the shoulders a³ ³ as represented in Figure 3. By the
descent of the plunger into the mould a the moulten glass is fashioned in the mould
and the glass bottle thereby partly made, the neck part of the bottle being formed
partly by the shoulders a³ ³ of the mould and partly by the cover h of the mould.
The partly made article thus pressed in the mould Figure 3 is represented in section
in the mould and detached in Figure 5. The plunger & being raised out of the
mould a the cover h is turned back on its hinge and the shoulders a³, as are lifted
from the mould a carrying with them the partly made bottle-connected by its neck
to the said shoulders. The combined shoulders and partly made bottle-are-now
transferred to the separate blowing mould 6 represented in Figure 4 the shoulders a³, as
being supported on the top of the blowing mould 6 in the position represented and
the partly made bottle passing into the mould as indicated in dotted lines. The
cover p carrying the blowing pipe q being passed into the neck of the pressed article
as represented in Figure 4, the said pressed article is blown in the mould b and
made to take the form of the said mould as represented in section in the mould.
The bottle made in the mould Figure 4 is represented-detached in Figure 6. The
cover and blowing pipe p q being removed the two halves of the shoulders as as are
unfastened and opened out and the finished glass-bottle is removed from the mould by
means of the lever - Figure 4.
Although in the accompanying Drawings I have represented the apparatus which I
prefer to use in carrying my invention into effect and which I have found to answer
well in practice yet I do not limit myself thereto as other kinds of apparatus may be
employed in conducting my method of manufacture.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed I declare that what I claim is :-
First Manufacturing glass bottles and glass jars and other like glass articles by
the combination of the processes of pressing and blowing, the said processes being
conducted substantially as herein before described and illustrated in the accompanying
Drawings.
Secondly-The apparatus herein before described and illustrated in the accompanying
Drawings to be used in the manufacture of glass bottles and glass jars and other like
glass articles by the method claimed in the first claim.
