Improvements in Machines for Punching, Cutting, Shearing
and the like.
I, JULIUS KEIM, Foreman of Works, of Weissenfels, in the Empire of Germany,
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 follow-
ing statement:
-
The present invention relates to a press, in which the pressing stamp has not
merely a single tool or die, matrix or the like, but by special construction of the
head of the press, any desirable number of tools entirely different in dimensions or
in their operations may be introduced.
The invention is shown in the annexed drawing in which Fig. 1 is a front view
of a press constructed according to this invention, Fig. 2 a part sectional side
elevation and Fig. 3 a plan of the same.
In the suitably constructed machine frame a, the eccentric shaft e furnished with
the eccentric and the handle d is seated. In place of the handle d, a pulley of
suitable dimensions may be employed equally well, or the whole driving apparatus
may be entirely replaced by one of those hitherto in use and suitable for the
purpose.
In
The press-head e of the machine is not massive in construction, as hitherto, but
in its outward appearance more resembles a rim or plate with centre aperture.
It is furnished at the back, as ordinarily, with dovetails, which, exactly as in other
apparatus of the kind, can be forced by means of screws and, adjusting blocks to
slide properly and surely on the prismatic guide f. In the middle of the press-
head e, is an opening g, bounded by arcs of different radii and acting as a cam.
the lower side of the opening g is a small semi-circular groove h, which serves
for guiding the pressure block i. The eccentric b in the present instance the
press driving pin, runs between the upper limit curve of the opening 9 and the
block i and therefore raises the whole apparatus, whilst when the eccentric pin
descends, the whole press-head is pressed down with the assistance of the pressure
piece i.
The revolving ring k is a characteristic feature of this press. It is exactly fitted
on to the part of the press-head e and is rotatably moveable thereon.
On the circumference of the revolving ring k is a suitable number of tools,
which may be of different dimensions or of entirely different kinds. For example,
a set of 4, 6 8 or more hole-punches may be placed on the ring, these punches vary-
ing from each other in regular degrees; or angle-iron cutters, shears, punches or
other implements may be placed on the revolver ring in any desired order.
The fixing of the ring to the piece for the purpose of exact adjustment of the
tools is effected, in a suitable manner by means of a set stud, a block, or in any
other suitable way.
The motion of the eccentric shaft c or of the eccentric b is followed by that
of the whole revolving ring as well of the instrument which has been adjusted for
cutting, the motion of the ring and head e being regularly up and down.

page_text: At a suitable distance below the revolving ring or the press-head a similar sup-
port to the one 7 herein before referred to for receiving the revolver ring is fixed
on to the machine frame a. This support also carries a revolving ring, which can
be fixed by means of blocks or any other suitable means, such ring conveying in
the same graduation, the matrices or counter-implements corresponding to the
punches or the like.
As will be seen from Fig. 1, the rings in the machine represented carry an angle-
iron cutter, shears, and six perforating or hole-punches. The tools can, as a
matter of course, be put together in any desired manner, however different the
driving apparatus for the machine may be, and whatever may be the fitting out of
the several parts, without in any way affecting the scope of the invention.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. A press with revolving head, characterised by a press-head, in the form of a
rim or plate with centre aperture, and moveable in a prismatic guide upwards and
downwards in a vertical plane by an eccentric, or by other suitable means, the
press head being furnished with a supporting piece, on which is a ring for carry-
ing any desirable number of tools of similar or dissimilar kinds, the position of the
ring for the adjustment of a particular tool for the cutting operation being secured
by a stud or in any other suitable manner; and also characterised by a similarly
formed ring which, having a similar position on a supporting piece of the machine
frame, and being likewise capable of being fixed, contains the matrices or counter-
tools to the tools of the movable head, so that by the simple rotation of the rings,
punches of different sizes and also tools of entirely different nature in their effect
may be brought into use.
2. The improved construction of machines for punching, cutting shearing or
the like substantially as described with reference to the drawings.
Dated this 22nd day of April 1898.
