PROVISIONAL SPECIFICATION
Improved Process and Apparatus for Stamping or Embossing
I, ANTON RICHARD BREINL, Maker of Musical Instruments for Children,
of Graslitz, Bohemin, in the Empire of Austria, do hereby declare the nature of
this invention to be as follows
-
This invention relates to a process and apparatus for stamping signs such for
instance as letters and words in or on sheet metal or other material
This process
can however only be employed with advantage where several signs are to be
stamped which have some common parts and others different the one from the
other
Hitherto it has been necessary to have as many stamps (punches and dies) as
the signs to be produced even if the signs only differed from each other in single
parts
According to my process only one stamp 1s employed which has cut or engraved
upon it those parts which are common to all the signs, while those parts which are
different are mutually interchangeable in such a stamp
The signs contained in the stamp or punch may for instance consist of three
line, 2 E A Present from "-" Weston-super-Mare - Made in Bohemia "
">
The first and third lines are permanently cut or engraved in the punch, while the
middle line is loose and interchangeable so that other words may be substituted
therefor
J
To this end the stamp or panch is provided with a groove wherein the letters
composing the centre line may be inserted singly or as a whole
Two set screws
when tightened up, after the insertion of the line, hold the interchangeable line
fast together
The letters on the punch are all raised, e in relief
For the matrix a smooth hard plate for instance of brass, is utilised, and has its
edges bevelled so as to fit into the correspondingly undercut aperture of a larger
plate Screws (passing through the larger plate) secure both the plates to a third
flat solid plate Bv this arrangemen the brass plate is made removable and
interchangeable
}
In stamping, a piece of sheet metal introduced between the punch and the
brass plate, letters in intaglio are formed he biass plate by the pressure applied
to the punch, and thus when other signs constituting another motto, are to be
stamped, the plate must be removed and another smooth plate must be substituted
therefor
In the interposed sheet metal strip appear the signs stamped by the punch
It is obvious that when the first motto is again to be stamped, that the brass
plate must be restored to its position in the matrix

COMPLETE SPECIFICATION
Improved Process and Apparatus for Stamping or Embossing
I, ANTON RICHARD BREINL, Maker of Musical Instruments for Children
of Graslitz, Bohemia, in the Empire of Austria, 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 process and apparatus for stamping signs such for
instance as letters and words in or on sheet-metal or other material
This process can, however, only be employed, with advantage where several
sigus are to be stamped, which have some common parts, and others different the
one from the other

Hitherto it has been necessary to have as many stamps (punches and dies) as
the signs to be produced even if the signs only differed from each other in single
parts

According to my process only one stamp is employed which has cut or engraved
upon it those parts which are common to all the signs, while those parts which are
different are mutually interchangeable in such a stamp
In the accompanying drawings is shown the apparatus for stamping the signs
Figure 1 is a face view of the punch, and
Figure. 2 a,longitudinal vertical section thereof, on the line x x of Figure 1
Figure 3 is a face view of the matrix, and
1
Figure 4 is a longitudinal vertical section of the same on the line y y of Figure 3
The signs contained in the stamp or punch may for instance consist of three lines
"A Present from "-" Weston-super-Mare "-"Made in Bohemia
"
The hist and third lines are permanently cut or engraved in the punch, while the
middle, line is loose and interchangeable, so that other words may be substituted
therefor
To this end, the stamp or punch is provided with a groove a wherein the letters
composing the centre line may be inserted singly (as shown in Figures 1 and 2), or
as a whole
Two set screws bb when tightened up, after the insertion of the line,
hold the interchangeable signs fast together
The letters on the punch are all raised, e, in relief
For the matrix a smooth haid plate e for instance of brass is utilised, and has
ats edges bevelled so as to fit into the correspondingly undercut aperture of a
larger plate d Screws e e (pa sing through the larger plate d) secure both the
plates to a third flat plate f By this arrangement the brass plate c is made
removable and interchangeable
In stamping, a piece of sheet metal is introduced between the punch and the
brass plate c, letters in intaglio are formed in the brass plate c by the pressure
applied to the punch, and thus, when other signs, constituting another motto, are
to be stamped, the plate c must be removed and another smooth plate must be
substituted therefor
In the interposed sheet metal strip appear the signs stamped by the punch
It is obvious that when the first motto is again to be stamped that the original
brass plate must be restored to its position in the matrix
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
-
1 A process for stamping several signs, which have parts alike and others unlike
in sheet metal consisting in cutting or engraving in the punch the like parts of the
signs while the unlike parts are made interchangeable so that only one punch 18
needed for all the sions

page_text: 2 For carrying out the process described in Claim 1 an apparatus consisting of
a punch (Figures 1 and 2) provided with a groove (a) wherein by set-screws (b b)
the interchangeable parts of the signs are respectively held fast, in combination
with a matrix (Figures 3 and 4) wherein a movable and interchangeable plate (c)
is held fast between the plates (d) and (f) by means of its bevelled edges and two
screws (e e)
