Improvements in Stamping or Printing Apparatus.
I, JOSEPH BOHENSKY, of 25 Schauzstrasse Eger, Bohemia, Gentleman, 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 stamping apparatus in which the setting of type for
forming the words, parts of sentences or entire sentences that require to be printed,
is effected in a simple and rapid manner.
The stamping apparatus is thus essentially and advantageously distinguished
from known constructions of stamping apparatus in which the stamping face bears
permanently a single combination of letters or words.
According to this invention the stamping apparatus consists of a number of
separately rotatable type wheels or discs arranged closely side by side, each of
which carries on its periphery all the letters of the alphabet and other suitable or
necessary symbols, such as numerals, marks of denotation &c.
When the
apparatus is being used, all the discs are held securely in the required position by
a suitable locking device, after releasing which, they can be rotated for the
purpose of bringing any required different combination of letters or symbols into
the stamping position.
On the accompanying drawing Figure 1 shews a side view partly in section of
the improved stamping apparatus; Figure 2 shews a vertical. cross section
thereof.
The apparatus consists of a greater or smaller number (according to require-
ments) of circular discs a mounted side by side loose upon a cylinder or tube b, so
that they can be rotated at will independently of each other.
These discs have on their periphery, tooth-like projections a' separated from
each other by rounded recesses a², and having impressed thereon a letter or other
symbol.
All the discs are enclosed in a cylindrical casing e, in the end surfaces c¹ c¹ of
which the ends of the tube b, serving as axis are fixed.
The lower part of the casing is widened out, and it is closed in at bottom by a
plate c², serving as base, which has a longitudinal opening in the middle, through
which project the lowest parts of all the type discs, which parts bear the letters &c.
that are to be imprinted.
The cylindrical part of the casing is provided at the top with a longitudinal
opening covered by a trough-shaped cap 9 which is formed with a threaded
opening g at its middle into which is screwed the handle d d' of the apparatus.
This handle is formed of two separable hollow parts d, 'd' screwed together as
shewn; the lower part contains a helical spring h, one end of which bears against
the closed upper end of the hollow, while the other end presses against the disc-like
enlargement of a locking bar i.
Од
The latter passes longitudinally through the entire apparatus, and its ends,
which are formed as handles project through slots in the ends of the cap g.
its underside the locking bari has two parallel longitudinal ribs 3, the cross section
of which corresponds to the rounded recesses between two projections a¹ of the type
discs, and the distance between which is equal to the distance between two.
contiguous projections:
The locking bar i being pressed down by the spring, is consequently made to
engage with its ribs in the grooves formed by hollows of the several discs when

page_text: these are in correct position, and thus the type discs will be held securely in that
position. For ensuring the said correct position it is not necessary first to adjust
the discs accurately by hand, as owing to the rounded form of the hollows a³ and of
the ribs, the latter will, in descending automatically bring the corresponding
hollows of all the discs in line with each other.
When the type discs a are thus locked by the bar, as shewn at Figure 2, a
certain type of each disc will project in the lowest position through the opening c
of the base e², which types on being served with colour, will print the desired
combination of letters or symbols for forming the required word, sentence &c. to
be impressed. For facilitating the accurate register of the printed word &c.
relatively to other matter on the paper, the ends of the casing are provided with
small projections k, of the same width as the type, and which are in line with
these.
If it is desired to form a different combination of letters &c., the locking bar i is
seized by its handles and is pushed upward, against the action of the spring,
until the part of the bar is above two pins 1 capable of sliding through the cap g,
so that on then pushing these inwards, their ends project under the part of the
bar and retain this in the raised position, in which its ribs are clear of the type
discs a.
The latter can then be separately rotated for effecting a different combination,
after which the pins 7 are drawn back as far as the stops on their inner ends will
allow, and the liberated locking bar is then forced by its spring to engage with the
type discs again. The spaces left between the type discs a and the bottom corners
of the casing serve for the reception of the inking pad m, and the ink bottle n.
The former is preferably made of the same sectional form as the locking bar, and
carries between two ridges a band, the width of which corresponds to the height of
the type, so that it serves to ink a single row of the latter. The openings in the
one end surface c¹ of the casing, through which the pad and bottle are withdrawn,
are closed by slides o.
The hollow in the upper part of the handle d serves for the reception of the
spatula for spreading the colour, and the separable handle thereof.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is :-
1. A stamping apparatus consisting of a number of contiguous discs a separately
revolvable upon an axis b fixed in a casing c which discs have on their periphery
tooth-like projections a' carrying type of any desired kind, and which are held in
position for printing by means of a spring locking bar i situated between the discs
and the handled d', such locking bar being provided with longitudinal ribs that
engage with rounded hollows a between the type of each disc, while when the bar
is raised so as to free the type discs, it is held by means of pins / sliding through
the cap g substantially as described.
2. In a stamping apparatus such as is referred to in the first claim, the
arrangement of lateral projections k on the end surfaces of the casing c in line
with the row of types which are to be printed and which project through the
opening of the casing, so as to ensure accuracy of register, substantially as
described.
.
3. In a stamping apparatus such as is referred to in the first claim, the
arrangement of an inking pad m and ink bottle n, as also the inking spatula
respectively in spaces within the casing and in the hollow of the removable part of
the handle d, substantially as described.
