Improvements in Means for Blowing Bottles or other Hollow
Glass Ware.
We DAN RYLANDS of Hope Glass Works Stairfoot near Barnsley in the County
of York, Glass Bottle Manufacturer and BENJAMIN STONER of No. 2 Dearne Terrace,
Stairfoot, aforesaid Mechanic do hereby declare the nature of our invention to be as
follows:-
According to our present Invention we construct an Air Compressing Machine
somewhat on the following principle. To the crosshead of an horizontal engine we
attach a ram which ram is connected to a working barrel fixed horizontally alongside
the engine cylinder and which ram works in such working barrell as follows-At one
end of this working barrel we fix a valve in such a way that when the ram is being
drawn by the working of the engine away from this valve it draws the valve open
and draws in a supply of air; but immediately the ram commences to travel back
this valve closes and the air thus drawn in is compressed by the ram and forced
through another valve on the top of the working barrel and to which latter valve a
conducting pipe is attached which conducting pipe conducts the compressed air to the
air receiver. To secure the satisfactory working of the valve at the end of the
working barrel we attach a spring in such a way that it helps to close the valve
immediately the ram has travelled its full distance outwards.
We fix or construct around the working barrel a water trough and we so arrange
this water that at one end of it the cold water can be running in whilst at the other
end the heated water can be running out and by applying this cold water to the
working barrel we keep it sufficiently cool to be constantly at work. On the top of
the receiver for the compressed air we fix a safety valve so that the amount of pressure
in such receiver can be regulated according to requirements-We prefer to have the
inlet pipe into this receiver at the top and at the bottom of this receiver we fix an
outlet pipe. This outlet pipe is constructed so as to carry the compressed air from
the receiver into the shop or working place where the bottles are to be blown and we
bring this pipe at a sufficient height over what is technically known as the mould hole
to allow of a suitable valve being fixed in such a way that the blower can bring this

page_text: valve down upon his blow pipe mouthpiece or end after he has put what is technically
known as his "parison" into the bottle mould-We construct this valve on the back
pressure principle and in such a way that when it is brought down upon the end of
the blow pipe the contact of the valve with the end of the blow pipe opens the valve
and when the bottle has been sufficiently blown up in the mould and the mouthpiece
containing the valve is removed the pressure of the air from within automatically
closes the valve. Between this valve and the iron tube which conveys the compressed
air from the receiver we fix a tube of indiarubber or other suitable material of sufficient
length to allow of the valve being easily brought in contact with the mouth of the
blowpipe. Another way to make this valve work adjustably is to attach to it a socket
tube with a stuffing box made on a similar principle to sliding gas pendants the other
end of which socket tube is of course attached to the air conducting pipe.
We fit this valve into a suitable frame of wood brass or other material which frame is
bedded with a suitable india rubber cup or washer so that the valve can be easily brought
on to the end of the blow pipe. In some cases the valve may be brought on to the end
of the blowpipe by hand but in other cases we so attach a foot lever that the blower
can bring the valve down by this means direct on to the mouth of the blowpipe. To
this foot lever is attached a spiral spring so that immediately the blower's foot is
removed from the lever it again works up and lifts the valve clear of the blowpipe
end.
In order to more effectually hold the two halves of the mould together during the
time the bottle is being blown we fix horizontally across the "mould hole" an iron bar
of suitable strength. We attach to this iron bar a lever which works a crank which
crank is connected to the mould lug in such a way that when the lever is pressed or
pulled in one direction it opens the mould and when pressed or pulled in the
contrary direction it closes the mould and with very little pressure in this lever
it keeps the mould firmly closed. On the ordinary system at present in use for
closing open and shut moulds the mould cannot be kept sufficiently firmly closed
during the time the bottle is being blown up. Or where preferred a suitable cam
arrangement may be adapted for closing the mould. Another important part of our
invention is applying the means herein before described for blowing bottles or other
hollow glassware with the mould in a horizontal or slightly inclined position instead
of blowing with the mould in a vertical position. In order to accomplish this we
cause the valve connected with the pipe which conducts the compressed air to travel
in a horizontal position and we so arrange this valve that when the blow pipe is
introduced into it a very small amount of air is allowed to pass down the blowpipe,
but by causing the valve to travel in a slot so arranged that it gradually brings more
pressure upon the valve the valve is made to open wider so that when the blowpipe
with the pressure at the end thereof is brought into the bottle mould immediately
such bottle mould is thoroughly closed the full necessary pressure for blowing up
the bottle in the mould is brought on the valve-The mould is kept closed by
suitable mechanical means while bottle is being blown.

Improvements in Means for Blowing Bottles or other Hollow
Glass Ware.
We, DAN RYLANDS, of Hope Glass Works, Stairfoot near Barnsley in the County
of York, Glass Bottle Manufacturer and BENJAMIN STONER, of No. 2, Dearne Terrace,
Stairfoot, aforesaid, mechanic, 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 :-
In carrying out our Invention we construct an air compressing machine and other
apparatus shown at Figs. 1, 2 and 3 of the accompanying drawings.
Fig. 1, is a sectional elevation of air compressing cylinder, together with elevations
of the engine sides and compressed air receiver.
Fig. 2. is a perspective part sectional elevation of improved air valve and arrange-
ment for blowing the bottles or other articles in the moulds.
Fig. 3. is a detailed sectional elevation of modified form of air pipe coupling.
To the crosshead A is attached a ram or rod B, which is connected to the piston C
of the air-compressing cylinder D. The said air-cylinder or working barrel Dis
fixed to side of the steam engine bed E. At one end of the working barrel Dis
arranged a valve F so that when the ram or piston C is drawn by the working of
the engine away from the valve F the pressure of the atmosphere forces the valve F
open and enters the vacuum formed in the cylinder D. Immediately the ram C
commences to travel back the valve F closes, and the air in the cylinder is forced
through the valve G and compressed into the conducting pipe H and receiver J. The
valve F has attached thereto a spring F by which means it is more readily closed
immediately the piston C takes its return stroke. The barrel D has arranged
around it a water trough K which receives cold water at L and ejects it at M;
by this means a constant circulation of water is kept up and the cylinder thereby
kept cool.
The receiver J has a safety valve N, and the inlet pipe H is preferably arranged to
conduct the compressed air into the top of receiver J as shown. At the bottom of
receiver J is the outlet or withdrawal pipe P which is arranged to carry the com-
pressed air from the receiver J into the shop or working place where the bottles or
other articles are to be blown; and the pipe P is brought sufficiently high to come
over or above what is technically known as the mould hole Q (Fig. 2) so as to allow
of a suitable valve S being fixed over the mould T. The "blower
can press the valve S
down upon his blow pipe mouth piece or end after he has placed the "parison" into
the bottle or other mould T. The valve S is constructed as follows an india rubber
washer S¹ is fixed into the hollow part S by means of a cap S³; at the top of the india
rubber washer S¹ is a diaphragm S which has small hole S for the air to pass
through the valve S is ground to the seating S7 and is held down thereto by means of
the spring V which is incased in a casing S. The casing S8 fits in the cylinder W

page_text: and is held up by means of the spring X. The cylinder W is either made with or
attached to the frame Y which is secured to the floor Z of shop. The valve S is pulled
down by means of the foot lever 3 which is connected to the part S2 by the rod 4.
Between the valve S and iron tube P is a tube of india rubber P' made of a
sufficient length so that the valve can be easily brought down upon the end of
blowpipe 2. Or instead of the pipe Plan arrangement shown at Fig. 3 may be usod,
in which case the pipe P1 is composed of iron and made straight; it works through a
gland P and can travel up and down in the pipe P as will be well understood.
In order to more effectually hold the two halves of mould T together during the
time the bottle is being blown, we fix across the mould hole Q an iron bar 5, attached
to which is a lever 6, and also a crank 7 one end of which works on a pin which is
attached to the lug T¹ of mould T.
The working of our herein described improved arrangements is as follows:-The
"blower" places the "parison" 8, which is attached to the blowpipe 2, into the
mould T; he then pulls the lever 6 which closes the mould T up tight, after which he
holds the pipe 2 in a vertical position and presses the lever 3 with his foot; this
brings down the valve S and presses the mouthpiece of blowpipe 2 into the india
rubber washer S¹, which presses the diaphragm S and lifts the valve S6 away from
its seating S7. By this means the compressed air from the receiver J (Fig. 1) is
forced down the pipe 2 into the "parison" 8 which is pressed out to the form of the
interior of the mould T by which means the said "parason." is blown into a bottle or
other article. After sufficient blowing has taken place the "blower's" foot is removed
from the lever 3 and the spring X lifts back the valve S and the valve S is pressed
down to its seating S7 by the spiral spring V thus stopping the escape of compressed
air. The lever 6 is then forced over, which opens the inould T and the bottle is taken
out in the ordinary manner.
Instead of having the mould T arranged vertically as shown, it may be horizontal
or slightly inclined, in which case we arrange the valve S so that when the blow pipe
is introduced into it a very small amount of air is allowed to pass along the said blow
pipe 2; this is accomplished by arranging the valve S to travel in a slot so that the
pressure of air is brought gradually more as the valve is pressed away, so that when
the blow pipe 2, with the parison 8, at the end, is placed in the mould, immediately
such mould is thoroughly closed the full necessary pressure for blowing up the bottle
or other article in the mould T is brought on the valve, as will be well understood.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what we
claim is
1. In the blowing of bottles or other hollow glass ware, the adaptation of compressed
air produced in the manner substantially as described and shown at Fig. 1.
2. In the blowing of bottles or other hollow glass ware, the adaptation of compressed
air used in connection with the arrangements substantially as described and illustrated
at Figs. 2 and 3.
