Improvements in connection with Punches and Dies therefor for
Punching or Perforating Paper, Cardboard, Thin Sheet
Fabric, and like Material.
I, PAUL MAHRENHOLTZ, of 27 and 28 Fischlerbrücke Magdeburg, in the
German Empire, Stencil Manufacturer, 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 :-
My invention relates to improvements in connection with punches and dies therefor
as used for perforating purposes, and consists of a method of constructing said dies
and punches and arranging them in multiple, so that designs, patterns, letters, or any
combination of such may be formed thereby, in manner similar to that of setting up
printers type, when, by the use of a suitable press constructed to carry in its head
the said combination of punches, and at its base a similarly arranged combination
of dies, so that the former may register truly with the latter, paper, cardboard,
thin sheet metal, or textile fabric if placed between the said punches and dies, may,
when these meet, receive perforations therefrom corresponding to the said pattern,
design, lettering or the like, thus rendering my invention useful for producing any
design or the like to order, in cardboard, silk, cloth or other material, that ladies
may use such perforations for cross stitch needlework in the production of book-
marks birthday or season cards, or for the ornamentation of dress material. Or
the said combination of punches and dies may be employed for perforating such
pattern or the like in thin metallic plates for stencilling and analogous purposes.
In order that my invention may be fully understood reference may be made to
the accompanying drawings, in which,
Figs. 1 and 2 are perspective views of a punch and die respectively according to
my invention.
Figs. 3, 4 and 5 are plan views of dies illustrating three out of many forms in
which these and their punches may be constructed and set up together in multiple
in the formation of patterns, designs letters or the like.
Fig. 6 is a perspective view illustrating the manner of setting up the said dies
(and their punches) in a frame similar to a printers chase, as hereinafter
explained.
In carrying my invention into effect, I form of steel or other suitable metal
a punch A such as Fig. 1, which may be formed with a head B, so as to be used
singly by the means of a hammer if desired, or made in the form of a cube as
at Fig. 2 which is the die C, to be used with Fig. 1, and in the latter would be
formed holes or passages a, arranged in any manner desired, and corresponding
with these, pins or studs would be formed upon or attached to the under surface
of the punch A, so as to register perfectly true with, and enter the said apertures a
when A and C are brought together.
In Figs. 1 and 2 I have chosen to show five such holes or apertures in C, and
five studs on A, and this pattern or its multiple is observed more or less throughout
the drawings, but it is obvious that these may be arranged in many other ways as
fancy and other circumstances may dictate. It is also obvious that the said
punches and dies may be other than square or rectangular in plan, an illustration
of which is shewn by an arrangement of dies in Fig. 3, the punches for which
would be formed to correspond therewith.

page_text: In practice, any number of said punches and dies would be made and kept in
stock, of various shapes, and having holes a and studs barranged in various ways,
and these may be assorted in founts after the manner of printers type, the object
of my invention being, that the said punches and their corresponding dies may be
set up in multiple in a frame or chase such as D, or its equivalent, as at Fig. 6, so
as to fit together in the same manner as printers type, and in filling such chase or
frame, blocks of wood F may be used, or when the said dies and punches are of
cubical form, the former of these may be turned sideways and used in lieu of, or
in combination with the blocks F, as illustrated by G in the same Figure 6, the
whole being tightened and held in position by blocks and wedges E as in the
manner of type setting.
In Fig. 6 is shewn the dies arranged to form the letter E, but whatever letter,
letters, design or pattern the said dies may be arranged to form-the punches
therefor would be similarly arranged in another chase or frame D
or its
equivalent, and fixed thereiu in like manner, and while the said punches would be
fixed or fitted to or into the head of a suitable vertical press, the said dies would
occupy a position at the base of same, care being exercised in fixing the punches,
that the pins b of the same, would, when descending, register with the apertures a
in the said dies below.
I am aware that punches such as A, and dies such as C, or their equivalents
have been employed for perforating purposes prior to my invention, but I am not
aware that these have hitherto ever been so constructed (as herein described) as
to be capable of being set up in multiple in manner similar to printers type, so
that any design, pattern, letter or letters could be formed therewith to order,
therefore,
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
The employment of punches such as A, of any desired shape or form, having
pins or studs such as b, arranged in any desired form or order, capable of
registering with similarly disposed holes or apertures a, formed in like or other
shaped dies such as C, and the manner of arranging both the said punches and dies
in multiple to form designs, patterns, letter or letters, and the manner of fixing
the same in separate frames or chases such as D or its equivalent, so that the one
combination may register with the other when fixed into and upon, and operated
by a suitable press, substantially as and for the purposes herein fully described and
shewn by the accompanying drawings.
Dated this 26th day of July 1895.
