I THOMAS EUNSON of 7 Aiskell Street, Sunderland in the County of Durham,
Glass Mould Maker, do hereby declare the nature of this invention to be as
follows:-
This invention consists in a press with moulds adapted to receive charges of
molten glass and means for compressing the same for the moulding of the glass.
This consists of a hollow casing or frame with closed top into which are fixed
two bars standing vertically, which act as guides to a crosshead connected at both
ends by rods to a crank shaft carried in the casing. The cranks be parts of
spur wheels. The crank shaft may be directly worked by any kind of power
available or by hand or a separate driving shaft may be provided and fitted with
two or more pairs of spur or other wheels in order to provide means for causing
varied pressures to be given by the plunger fitted to the crosshead.

The plunger is in two pieces, the smaller piece working in and through the large
The large part of the plunger is screw threaded and provided with nuts for
regulating and fixing its position in the crosshead. The upper end of the smaller
plunger is provided with a collar to keep it from dropping out of the larger piece;
a cap is screwed on the top of the larger piece and has in it a spiral spring which
presses upon the top of the smaller plunger, the pressure of the spring being
regulated by the adjustment of the cap. The lower end of the inner or smaller
piece of the plunger is provided with a flange or other means for fixing to the
internal or movable part of the mould. Connected by two nuts to the lower part
of the large piece of the plunger is a plate which is again connected to a similar
plate by distance bolts embraced by spiral springs. The object of fixing this or a
similar arrangement to the larger part of the plunger is to hold down part of the
mould while the small or internal plunger is compressing the fluid glass.
On the crank shaft and inside the casing is fitted an eccentric or crank which
works a rocking shaft provided with levers for actuating a pawl or ratchet wheel
on a shaft carried by the casing. On the shaft is a bevel wheel gearing with a
pinion on a vertical shaft in the centre of the casing and carrying the table to
which the moulds have to be fixed. The table is carried and revolves on rollers
which may be jourualled on either the table or the casing or may be in a separate

be provided with three moulds (but the number is not limited) then during one
revolution of the crank shaft by means of the pawls, ratchet wheel and bevel gear,
the table should move through one-third of a revolution, so that every time the
plunger descends a mould will be beneath it, and at the same time one mould will
be filling and the other emptying. Beside the driving pawl, check and stop pawls
are provided, also a locking bolt which fits into suitable notches in the table and is
actuated from the crank shaft. Also on the crank shaft is a lever or striking bar
which by means of other levers and rods forces the article moulded out of the
mould a certain distance to facilitate emptying the mould. The casing or frame
may be fixed to the floor or it may be provided with rollers for easier removal.

page_text: I THOMAS EUNSON of 7 Aiskell Street, Sunderland in the County of Durham,
Glass Mould Maker, 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 :-
This invention consists in a press with moulds adapted to receive charges of
molten glass and means for compressing the same for the moulding of the glass.
In the annexed drawings Fig. 1 is a front elevation Fig. 2 a plan and Fig. 3 a
side elevation of the improved press.
The press consists of a hollow casing or frame B with closed top into which are
fixed two bars C standing vertically which act as guides to a crosshead E connected
at both ends by rods K to a crank shaft Q carried in the casing. The cranks may
be parts of spur wheels f. The crank shaft may be directly worked by any kind of
power available or by hand or a separate driving shaft T may be provided and
fitted with the members e c of two or more pairs of spur or other wheels c d e f in
order to provide means for varied pressures to be given by the plunger fitted to the
crosshead.
The plunger is in two pieces, the smaller piece G working in and through the
large one F. The large part F of the plunger screw threaded and provided with
nuts for regulating and fixing its position in the cross head. The upper end of the
smaller plunger is provided with a collar to keep it from dropping out of the larger
piece, a cap H is screwed on top of the larger piece and has in it a spiral spring J
which presses upon the top of the smaller plunger the pressure of the spring being
regulated by the adjustment of the cap. The lower end of the inner or smaller
piece of the plunger is provided with a flange K or other means for fixing to the
internal or movable part of the mould. Connected by two nuts to the lower part
of the large piece of the plunger is a plate h which is again connected to a similar
plate by distance bolts embraced by spiral springs j. The object of fixing this
or a similar arrangement to the larger part of the plunger is to hold down part of
the mould while the smaller or internal plunger is compressing the fluid glass.
"
On the crank shaft Q and inside the casing is fitted an eccentric with strap M
or a crank which works a rocking shaft N provided with lever for actuating by
means of a pawl q, a ratchet wheel P on a shaft L carried by the casing. On the
shaft L is a bevel wheel a gearing with a pinion b on a vertical shaft in the centre
of the casing and carrying the table A to which the moulds have to be fixed. The
table is carried and revolves on rollers V which may be journalled on either the
table or the casing or may be in a separate ring. A suitable path or paths is
provided for the rollers. If the revolving table be provided with three moulds
(but the number is not limited) then during one revolution of the crank shaft Q
the pawl ratchet wheel P and bevel gear a b should move the table through one-
third of a revolution so that every time the plunger descends a mould will be beneath
it and at the same time one mould will be filling and the other emptying. Beside
the driving pawl 9 check and stop pawls R S are provided, also a locking bolt U
which fits into suitable notches in the table and is actuated from the crank g by
lever W. Also on the crank shaft is a lever or tappet X which by means of
another lever Y and rods Z u forces the article moulded out of the mould a certain
distance to facilitate emptying the mould. The casing or frame may be fixed to
the floor or it may be provided with rollers for easier removal.
p is a clutch on shaft Q for disengaging the eccentric M.

page_text: Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that
what I claim is :-
1. The press for pressing moulded glass comprising the rotary table A with
suitable gear for operating in, and the divided press bar F. G for the purpose
described.
2. The construction said press with means for intermittent rotary movement
of table A and for operation of the divided press bar F. G substantially as described
with reference to the drawings hereto annexed.
