We, JOHN KEATS of Bagnall, near Stoke-upon-Trent in the County of Stafford,
Engineer, and ARTHUR KEATS of 41 Gaol Road, Stafford, Machine Maker, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a novel arrangement of cutting press which facilitates the
cutting operation, ensures protection to the workmen engaged in operating the press,
and at the same time provides for the exact adjustment of the dip of the presser
plungers.
All the mechanism of the press we arrange within the framing in such a manner
as to prevent the driven parts from catching the arms or the garments of the
operators.
We prefer to make the press double acting, or suitable for two workuien, who will
alternately set the press in action by means of treadles provided for the purpose.
These treadles are fulcrummed on a pair of cast iron standards which preferably
torminate at about the height of the work tables, of which there are two, supported
by brackets on the standards, one table for each workman.
Upon these standards, are set up and secured by bolts, a pair of side plates which
are connected together by transverse castings bored out to receive each a cylindrical
plunger.
These plungers are connected loosely to, and serve to balance, a beam fulcrummed
in the upper part of the side plates.
Pendent from this beam, at opposite sides of the fulcrum, are two connecting rods
carrying at their lower ends excentric straps, which straps fit each an excentric keyed
to a transverse shaft having its bearings in the upper part of the standards.

page_text: A spur wheel on this shaft gears into a spur pinion keyed to a crank shaft having
also its bearings in the standards.
The cranks of this shaft stand in opposite directions, and they are severally
connected by a hooked rod pivotted respectively to the treadles before mentioned.
The crank shaft is also provided with fly wheels within the standards for equallizing
the motion of the crank shaft.
The excentrics are so arranged on their shaft as to act alternately on the rocking
bean (with which they are connected), and thereby to depress the plungers at its
pposite ends alternately.
The plungers are made in two parts to admit of the adjustment of their length to
suit the depth of cutter employed.
The upper part of the plunger, or that which is connected directly to the beam, is
bored out from its lower end, to receive within it a cylindrical extension of the lower
part of the plunger.
This cylindrical extension is itself bored out and threaded to receive a screw fixed
centrally in the upper part of the plunger.
When therefore it is desired to increase or diminish the length of the plunger, it
will only be necessary to turn, and thereby to slile up or down, the lower part, or
that which is brought into contact with the cutter on the table of the
press.
To adjust the plungers to their work, the skeleton stamping cutter, which is to be
employed, say, for stamping out the sole of a boot, is placed on the table imme-
diately below its plunger, and the length of the plunger is adjusted by screwing until
it, at the lowest position of the beam, touches the back of the cutter.
When the plungers have been thus adjusted, the press is ready for use.
The work to be stamped out is placed under the cutter, and the plunger coming
down, will force the cutter through the work, after which the plunger will rise to
provide for the readjustment of the work and a repetition of the stamping operation.
It will be understood that the workmen standing at opposite ends of the machine will
alternately adjust their cutters on their work, and by depressing their treadles will
bring into action their respective plungers.

page_text: We JOHN KEATS of Bagnal near Stoke-upon-Trent in the County of Stafford
Engineer and ARTHUR KEATS of 41 Gaol Road, Stafford, Machine 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 relates to a novel arrangement of cutting press which facilitates the
cutting operation, ensures protection to the workmen engaged in operating the press,
and at the same time provides for the exact adjustment of the dip of the pressing
plungers.
All the mechanism of the press we arrange within the framing in such a manner
as to prevent the driven parts from catching the arms or the garments of the
operators.
We prefer to make the press double acting, or suitable for two workmen, who
will alternately set the press in action by means of treadles provided for the
purpose.
In the accompanying drawings :-
Fig. 1 shews in side elevation, and
Fig. 2 in end elevation, a double acting or compound cutting press constructed
according to our invention.
In these Figures, AA is a pair of cast iron standards, which terminate at about.
the height of the work tables B B, of which there are two, one table for each work-
man. These tables, which are made preferably of cast iron, are supported by brackets
projecting from the inner faces of the standards A.
Upon these standards are set up, and secured by bolts, a pair of side plates A',
which are connected together by transverse castings A2 A2, bored out to receive
each a cylindrical plunger C, the details of construction of which will be hereafter
explained.
These plungers are connected loosely to opposite ends of a beam D, fulcrummed
in the upper part of the side plates A', and projecting through vertical slots made in
the back of the castings A³, to reach the plungers. This beam D is connected to the
plungers by pins passed through lugs projecting from the head of the plungers, and
being thus balanced, it serves, when set in action, to impart an oasy up and down
motion alternately to the two plungers.
Pendent from this beam, at opposite sides of the fulcrum, are two connecting
rods E E, carrying at their lower ends excentric straps, which straps embrace each

page_text: an excentric F, keyed to a transverse shaft F¹, having its bearings in the upper part
of the standards A.
F2 is a spur wheel on the excentric shaft F', which gears into a spur pinion G
keyed to a crank shaft G, having its bearings also in the standards A.
The cranks of this shaft stand in opposite directions, and they are severally
connected by a hooked rod G2 pivotted respectively to one of a pair of treadles H.
These treadles each consist of a pair of arms braced together by the foot board and
a transverse bar, and to these transverse bars the hooks G2, which are screwed at
their lower end, are adjustably attached by means of nuts.-]
-Each pair of arms has
for its fulcrum a transverse rod mado fast to the standards A near the ground
line.
The crank shaft G¹ is also provided with fly wheels G³ within the standards, for
equallizing the motion of the crank shaft.
The excentrics are so arranged on their shaft as to act alternately on the
rocking beam (with which they are connected) for depressing the plungers CC
alternately.
The plungers are made in two parts (see the detached sectional view Fig. 3) to
admit of the adjustment of their length to suit the depth of the cutter employed, the
one part sliding, for this purpose, telescopically within the other.
The upper part of the plunger, or that which is connected directly to the beam,
is bored out from its lower end to receive within it a cylindrical extension (of the
lower part of the plunger.
This cylindrical extension is itself bored out, and threaded to receive a screw c,
fixed centrally in the upper part. C of the plunger.
When, therefore, it is desired to increase or diminish the length of the plunger,
it will only be necessary to turn, and thereby screw up or unscrew the lower
part C, or that which is brought into contact with the cutter on the table of the
press.
In order to adjust the plungers to their work, we place the skeleton stamping
cutter I (see Fig. 1), which is to be employed, say, for stamping out the sole of a
boot, on the table B, immediately below its plunger, interposing between the cutter
and the metal table a block of wood. We then adjust the length of the plunger by
screwing it up or down, until the plunger, when brought down to its lowest position
by the bean D, just touches the back of the cutter.
When the plunger has been thus adjusted, the press is ready for use.
The work to be stamped out is then placed under the cutter and upon the wood
block, and the plunger coming down, will force the cutter through the work; after
which the plunger will rise to provide for the adjustment of the work and a repetition
of the stamping operation.
It will be understood that when the machine is arranged for full working, the
workmon standing at opposite ends of the machine will alternately adjust their cutters
on their work, depress their respective treadles, and bring into action their respective
plungers, which pressing on the cutters placed beneath them, will force the cutters
alternately through the work presented to them, irrespective of the thickness of the
material to be cut through.
When, however, one plunger only is required to be used, it will be depressed, as
before, by the treadle with which its end of the beam is connected, but on the treadle
being released from pressure of the workman's foot, the counter-balanced beam,
assisted by the momentum of the fly-wheel, will lift the acting plunger clear of the
cutter, and allow the workman to re-adjust his work in the same manner as when the
two treadles were alternately in action.
As an obvious modification of the above described press, we propose to make
the beam D with a pendent extension, as shown in the diagram Fig. 4. This
extension piece we fit with brasses to embrace an excentric F fitted to the excentric
shaft F. As, therefore, the shaft is rotated, the excentric will rock the beam D, and
depress the plungers C dependent therefrom, alternately, in precisely the same manner
as they are operated by the two excentrics in the first described arrangement.

page_text: 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 :-
1st. The construction of double acting cutting press as above described, in which
the rotating mechanism is contained within, and covered by the framing, for the
purpose set forth.
2nd. The rocking beam balanced by the plungers, and actuated from a single
excentric shaft as described.
3rd. The construction of extending and contracting plunger for cutting presses as
described.
