We, ADAM MASON, and HERBERT EVANS MASON, both of Montcliffe, Horwich
near Bolton in the County of Lancaster, Bessemer Tuyere and Fire Brick Manu-
facturers, do hereby declare the nature of our Invention for IMPROVEMENTS IN
APPARATUS FOR MANUFACTURING TUYERES, STOPPERS; NOZZLES, AND OTHER
SIMILAR ARTICLES," to be as follows:-
This invention relates to improvements in apparatus for manufacturing Tuyeres,
Stoppers, Nozzles, and other similar articles and consists in constructing a Hydraulic
or other stamp or press with means for automatically lifting the bottom moulds
when the centre or other peg is clear of the mould.
The press (by preference) is of the hydraulic kind supported on standards
mounted on a metallic base plate. This plate is provided with a cavity or box
extending downwards for receiving the moulds; the top side being constructed
with a slide on which the moulds are held which allows the same to be drawn
sideways when being charged with materials from which the articles are to be
manufactured, after which the slide and the mould are pushed under the centre of
the press, when the hydraulic valve is operated which causes the piston to descend
with the cage and attachments into the inould.
On the cage is mounted a suitable mould and centre peg or pegs, being kept in
their true position by suitable slides attached to the standards.
For the purpose of lifting the piston or ram carrying the bottom mould suitable
lever arrangements are provided, being attached to the cage by a pin or other equi-
valents, which slide in a slotted lever and raises the same immediately the cage
attachments are clear of the mould,
To the base plate or to the standards is attached an adjustable guide or bow for
the purpose of regulating, the position of the moulds according to the various sizes
employed.
If desired our improvements may be applied to presses or stamps operated by a
screw, or lever, or by. steam; the apparatus being attached in any suitable or
convenient manner.

We, ADAM MASON and HERBERT EVANS MASON, both of Montcliffe, Horwich
near Bolton in the County of Lancaster, Bessemer Tuyere and Fire Brick Manu-
facturers, do hereby declare the nature of our said 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 relates to improvements in apparatus for manufacturing tuyeres,
stoppers, nozzles, and other similar articles and consists in constructing a hydraulic
or other stamp or press with means for automatically lifting the bottom moulds
when the centre or other peg is clear of the mould.
The press (by preference) is of the hydraulic kind supported on standards
mounted on a metallic base plate. This plate is provided with a cavity or box
extending downwards for receiving the moulds; the top side being constructed
with a slide on which the moulds are held which allows the same to be drawn
sideways when being charged with clay, cement, and other analogous material from
which the articles are to be manufactured, after which the slide and the mould are
pushed under the centre of the press, when the hydraulic valve is operated which
causes the piston to descend with the cage and attachments into the mould.
On the cage is mounted a suitable mould and centre peg or pegs, being kept in
their true position by suitable slides attached to the standards.
For the purpose of lifting the piston or ram carrying the bottom mould suitable
lever arrangements are provided being attached to the cage by a pin or other equi-
valents, which slide in a slotted lever and raises the same immediately the cage
attachments are clear of the mould.
To the base plate or to the standards is attached an adjustable guide or bow for
the purpose of regulating the position of the moulds according to the various sizes
employed.
If desired our improvements may be applied to presses or stamps operated by a
screw, or lever, or by steam; the apparatus being attached in any suitable or
convenient manner.
In order that our Invention may be more fully understood and readily carried
into operation we will now refer to the drawings hereunto annexed:-

Referring to Figs. 1, 2, 3, and 4; C is the hydraulic press cylinder mounted on
the standards D. The standards D are mounted on the base plate E and secured
thereto by bolts or their. equivalents. The standards D are provided with the
slides F on which the cage G slides when operated in either direction by the
piston H. The piston H is attached to the piston rod I; the cage G being attached
to the bottom end of the latter. The base plate E is provided with the cavity or
box J for the purpose of receiving the bottom mould K, or other suitable moulds
according to the form of the articles being manufactured. For the purpose of
lifting the bottom mould, the piston or ram L is attached to the rod M connected
to the lever N pivotted on the fulcrum or centre O, the latter being secured to the
crossbar P let into the foundation. To the opposite end of the lever N is attached
the rod R, the top end being slotted as in Fig. 4, which allows the cage G to move
upwards a certain distance to raise the peg T clear of the mould before the bottom
mould is lifted. The rod R is attached to the cage G by the arm S.
The top side of the base plate E is provided with the slide V on which the
plate W carrying the mould X slides, which allows the latter to be moved sideways
into the position shewn in Fig. 2, at which point the mould is charged with clay
or other substance from which the articles are to be manufactured, after which it
is slid under the press as in dotted lines in Fig. 2, being arrested in its true
position by the adjustable screws 9 mounted in the guide or bow 10. The
guide or bow 10 is secured to the standards D by the set screws 11, or their
equivalents.
The press is operated by moving the lever 12 attached to the four way valve 13,
which admits water to and emits from each end of the cylinder according to its
motion up or down.
Referring now to Figs. 5 and 6:-
This is an exemplification of our Invention applied to a hand screw press. The
cage G is operated by the screw I from the double lever 12. The lever arrange-
ment is similar to that before described, being attached to the cage by the arm S.
The standards D support the bush C in which the screw I operates.
Figs. 7 and 8, shew a modification of our Invention applied to a hand lever
press, the lever arrangement for raising the bottom mould being attached to the
cage G by the arm S.
The standards D support the guide C in which the ram I
moves. The ram I is attached to the hand lever 12 by the link 14, which, as the
lever 12 is operated, moves the cage G and its appendages in contact with the
mould and its contents.
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. The method, substantially as herein described, of automatically lifting the
bottom mould of a press employed for manufacturing tuyerers, stoppers, nozzles,
and other similar articles, by connecting the ram or piston carrying the same to a
moving cage or other analogous moving part, which takes place when the peg or
pegs are clear of the mould.
2. In apparatus operating in the manner referred to in the preceding claim, in
combination with a lever arrangement, connected to a moving cage by a slotted
rod, arranged so as to raise the bottom mould when the peg or pegs are clear of the
same, substantially as herein described.
