COMPLETE SPECIFICATION.
Improved Machine for the Manufacture of Glass Bottles, Jars, and
the like.
We, FREDERICK JOYNSON, Chemical Engineer, of Heatherlea, Penketh, WILLIAM
HARRISON, Mechanical Engineer, of 196, Padgate Lane, both of Warrington, in the
County of Lancashire, and GEORGE THOMAS JOYNSON, Surgeon, of Parkfield, North-
wich, in the County of Cheshire, 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 :-
Our invention consists of a machine for the manufacture of glass bottles, jars, and
the like, and has for its object to produce a handy and compact machine well
adapted for manual operation, and more convenient and efficient than heretofore,
and which may when so desired be readily moved about from place to place as
required.
We will describe our invention in reference to the accompanying drawings, in
which Fig. 1 is a front elevation, and Fig. 2 a plan of our improved machine.
According to our invention the operative machine is carried upon a bed or
foundation plate A which may be bolted down or mounted on wheels or rollers Bas
illustrated for convenience in moving it about the furnace or otherwise as required.
To this is bolted a central column or support Cupon which at any suitable height
for manual operation is arranged a circular revolving platform or mould-carrying
table D arranged and adapted to be easily rotated by hand and locked in certain
positive positions by means of a stop catch E mounted upon a vertical bracket F and
adapted to engage notches such as H formed in the underside of the outer flange d
of the said rotary table 1). Circularly arranged and equidistantly spaced around the
circumference of the table D are a number of interchangeable pressing moulds I
adapted to fit and pass through corresponding apertures in the table and have therein
a vertical movement in guides or sleeves J secured to the underside of the table D.
The required vertical motion is imparted when required by a reciprocating plunger
or lifter M working in guides or as illustrated in a bracket P fixed to column Cor
otherwise conveniently. This lifter is adapted to be raised and lowered by operation
of a hand lever Larrauged in convenient position for the operator and centred in a
standard upon the base plate A and connected to the lifter M by a system of
levers such for example as illustrated at K and N, a collar O being provided,
and a counterweighted lever R' for the purpose of assisting the operator in raising
the moulds.
Fitting upon the pressing moulds 1, interchangeable and detachable neck or mouth
moulds S, each formed in two parts hinged together at s, are provided, and the
lower surfaces of these are formed and adapted to fit closely upon and make a tight
joint with the reversely formed upper side of the said pressing moulds I.
Upon the upper part of the central column C is mounted an arm or bracket T
which carries a downwardly projecting stationary moulder U. This is adjustable as
required by means of set screw ut, and it is fitted concentrically at and about its lower
end with a sleeve W. Attached to the lower end of this sleeve is the lip moulder V,
and the whole is arranged to have a vertical motion against the force of a downwardly
acting spiral spring Y, suitable guides or slots being formed, for instance as illustrated
at X. The stationary moulder U is of hollow or tubular construction, the lower

page_text: portion being detachable and interchangeable to suit varying sizes of corresponding:
moulding blocks I upon the table D.
For the purpose of preventing overheating during the hot pressing process, we
provide a water circulating arrangement consisting of a pipe a passing down the
interior of the moulder U and conveying cold water from a tank Z supported upon
the before mentioned bracket T to the bottom of the moulder U, the heated water
returning by the annular space between the internal. pipe a and moulder U to upper--
side of tank Z by a flexible pipe a'.
Upon the column C between the platform D and bracket T aforesaid is arranged a
collar B' adjustable as to its position and supporting a circular or radially armed
table or bracket B2 of less diameter than the lower table D and adapted to clear the
stationary moulder U when rotated; at equal distances from the centre of column C
and also from each other we arrange upon and secure to this table B' the blowing
moulds C, the function of which is to form the bodies of the jars or bottles.
Each of these moulds is provided with an internal false bottom formed with a
downwardly extending arm passing out through guides and projecting below
the table B and each is provided with an anti-friction roller D'.
Beneath the line of travel of these rollers on rotation of table B' and fixed to
the central collar B' is an inclined cam-like elevator D' arranged in such position
that on rotation of the arined table B2 each arm will he successively raised up
for such distance as to eject the jar Q from the mould C, as shown to the right of
Fig. 1.
The blowing cap E adapted to fit upon any of the moulds C is hinged at e upon
a collar E secured to the column C, and it is connected to an air-blowing pipe F with
tap F for controlling the air pressure during the blowing process.
In operation the usual and proper quantity of molten glass (according to the
size and kind of mould in the machine) is poured into the pressing mould I,
the table D is then revolved by hand until the charged mould is brought
centrally and vertically below the stationary moulder U and locked in accurate
position by the catch E and notch H. The month or neck mould S having
been placed in position upon the charged pressing mould, the lever L is
pulled down, thereby through levers K and N raising the plunger or
lifter M and the pressing mould I until it meets the lip mould V which passes into
the recess S formed in the upper part of the neck mould S to receive it; the
operation being continued, the mouth or lip mould V and sleeve W are raised against
the action of spring Y which securely locks the parts together, and the stationary
moulder U enters the mould pressing out the glass into the mould and forming the
required configuration of lip or neck and inverted cone shaped impression of glass as
shown at G to the left of Fig. 1 suitable for the blowing process.
The lever L is then returned and the pressing mould I and all the parts assume
their initial position, the catch is released and the table D again rotated and so on.
The contents of the mould I may now be removed by the neck mould and placed
in the blowing mould C' the interior of which is of the form desired for the
finished bottle; the upper part of this mould is also formed reversely to and adapted
to make a tight joint with the underside of the neck mould S. The table or bracket B²
is then rotated until the mould C comes beneath the blowing cap E' which is turned
down upon its hinge and held or secured upon the mould, making a tight joint there-
with. The compressed air tap F is opened and the cone shaped piece of giass blown
to the internal form of the body mould (.
The jar or bottle having now been made, the air tap F is closed, the hinged cap
raised up, and the divided neck mould opened, and removed; then further rotation
of the table or bracket B by the next succeeding operation causes the lower arm of
the false bottom of the blowing mould last used to travel up the elevator or
inclined path D and thereby raise the finished bottle or jar for a sufficient distance
out of the mould for easy removal.
The illustration shows eight pressing moulds on table D which we find a con-
venient number, but it is obvious that a greater or less number may be employed.

page_text: The pressing process being carried on with one mould whilst others are
being filled or blown, all the operations may practically be carried on as a
continuous process.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The combination of the various parts constituting a complete machine for the
manufacture of glass bottles, jars, or the like, all arranged and adapted to operate.
substantially in the manner herein described and illustrated in the accompanying
drawings.
2. In a machine of the kind above referred to, the arrangement of the adjustable
stationary moulder U carrying sleeve W and lip mould V, with spiral spring Y, in
combination with the rotatable pressing moulds I and neck moulds S, all arranged
and adapted for use substantially in the manner and for the purposes hereinabove
described and illustrated in the drawings.
