page_text: We, MAX BERGER and CARL BERGER, Manufacturers, of Merseburg, Germany,
do hereby declare the nature of this invention to be as follows:―
The improved punching and cutting machine has the following peculiarities as
compared with the arrangements hitherto in use, namely that
1.) Always several spindles act at the same time.
2.) It can be simultaneously used for punching and cutting.
3.) The machine can be employed as shears. The arrangement of the machine
is as follows:
On a suitable support or foundation is fixed a base plate, which carries the
matrice stock and the cutters. Besides, this base-plate carries guide columns, to
which are secured a fixed cross beam serving as nut-holder, and an adjustable
cross-beam, serving as stamp guide. From the nut holders project three vertical
spindles, the middle one of which is provided with right screw thread and the two
others with left screw thread. Besides a spur-wheel, the middle spindle carries a
fly wheel, by means of which the machine is actuated. By turning the fly wheel
the spindles are uniformly moved by means of tooth wheels, and the axial motion
of the spindles (produced by turning the spindles in the nuts) is communicated to
the punches or knife carrier. The punches are situated in the punch carriers,
which are guided in the cross beam and so connected with the extremities of the
spindles, that the latter can turn in the punch carriers. The punches with the
knives are suitably fixed to the stamp or punch carriers, and the knives are either
straight or angular according to the pieces to be cut (for instance for hexagonal
nuts).
The matrix block carries guides, into which the bars or plates serving as raw
material to be punched is introduced.
For allowing the finally cut and stamped piece to be commodiously removed
from the said guides, pushers are employed, which consist of bolts, fixed to a rail,
which is provided at one end with a handle and pivoted at the other end. By the
motion of this rail all bolts are shifted into the guides, and the pieces, situated in
the same, are removed.
To allow this operation to be performed in spite of the bars, situated before the
fixed guides, these bars are supported by springs, which raise the bars slightly
after the piece has been cut off, so that the finished piece can slide from under
the same

page_text: When the bars are again fed forward, they are pressed down by means of a
borizontal rod and again brought into the fixed guides, where they abut against
the stop bolt mentioned above, according to the size of the piece. The bars on
entering the machine, are first clipped in a cross rail, which slides on a pair of
longitudinal rails and is connected with a revolving shaft by flexible bands. By
turning the said shaft by means of a crank, the bands are coiled up, and thereby
the slide is moved towards the knife.
For employing the machine as simple shears, the guide beam, which carries the
knife, is bolted to the stamp or punch carriers. One of the matrix blocks (the rear
one) is screwed off, so that the lower knife lies free.
Besides, the set screws, which connect the guide beam with the stationary posts
or columns are loosened, so that the guide beam can now follow the up and down
motion of the spindles.
The machine can be used for the manufacture of various wholesale articles, and
the punches can be replaced by pressing stamps or dies.

page_text: We MAX BERGER and CARL BERGER, of Merseburg Germany Manufacturers,
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:
The improved punching and cutting machine represented in the accompanying
drawings has the following peculiarities as compared with the arrangements
hitherto in use-namely that, first,-several spindles act at the same time-
second-It can be simultaneously used for punching and cutting, and thirdly the
machine can be employed as shears. The arrangement of the machine is as
follows.
On a suitable support or foundation is fixed a base plate A which carries the
matrix stock a and the cutters. This base plate carries also the guide columns B
to which are secured a fixed cross beam C serving as a nut holder, and an
adjustable cross beam D. serving as stamp guide. From the nut holders project
three vertical spindles E E¹ E-the middle one of which is provided with right
screw thread the two others with left screw thread.
In addition to the spur
wheel the middle spindle E carries a fly-wheel G by means of which the
machine is actuated. By turning the fly wheel G the spindles E¹ E E' are
uniformly moved by means of the tooth wheels F¹ F F. The axial motion of the
spindles produced by turning in the nuts is communicated to the punches or knife
carrier G G G³. The punches b are situated in the punch carriers which are
guided in the cross beam D and so connected with the extremities of the spindles'
that the latter can turn in the punch carriers. The punches b with the knives are
suitably fixed to the stamp or punch carriers and the knives are either straight or
angular according to the pieces to be cut (for instance for hexagonal nuts).
The matrix block carries guides c into which the plates serving as raw material
to be punched are introduced.
-
For allowing the finally cut and stamped piece to be comodiously removed from
out of the said guides, pushers H are employed which consist of bolts fixed to a
lever J which is provided at one end with a handle and pivoted at the other end-
By the motion of this rail all bolts are shifted into the guides c and the pieces
situated in the same are removed. To allow this operation to be performed in
spite of the strips situated before the fixed guides, these strips are supported by
springs which raise the strips slightly after the piece has been cut off, so that
the finished piece can slide from under the same. When the strips are again fed
forward they are pressed down by means of a horizontal rod e and again brought
into the fixed guides c where they abut against the stop bolts H according to the
size of the piece. The strips on entering the machine are first clipped in a cross
rail which slides on a pair of horizontal rails g g¹ and is connected with a
revolving shaft i by flexible bands h. By turning the said shaft by means of a
crank k and bands h are coiled up and the slide thereby moved towards the knife.
For employing the machine as simple shears the guide beam D which carries the
knife is bolted to the stamp carriers Q G Q³. One of the matrix blocks a is

page_text: screwed off so that the lower knife lies free. The set screws m are loosened so
that the guide beam can now follow the up and down motion of the spindles.
The machine can also be used for the manufacture of various articles and the
punches can be replaced by pressing stamps or dies.
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. A punching stamping and shearing machine having several spindles E E¹ E³
provided with punches, dies, or knives, or carrying by means of a cross beam D.
one knife, in which latter case the spindles are all connected with the cross
beam D.
2. In the machine described in Claim 1.
(a.) The lever J with pushers H.
(b.) The springs & combined with the rod e.
(c.) The feed mechanism consisting of cross bar f. sliding on rails g g' and
ectuated by shaft ; through strans h-substantially as described and
