Improvements in Platen Presses for Printing Cards and such like.
I, JOHANN SEBASTIAN HERBST of Munich, in the Kingdom of Bavaria,
Empire of Germany, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to platen presses and has for its purpose to allow cards and
such like to be printed in a most simple manner without the necessity of feeding
every single card to and removing it from the press.
A slide is movable in a suitable guiding provided underneath the working table.
This slide has a suitable number of vertically adjustable catchers elastically lodged in
corresponding guide pins. These catchers project, according the thickness of the
card to be printed, through slots, from the working table. Said slide also carries,
elastically lodged in angle pieces the ink roller, which, with the reciprocating
movement of the slide, distributes the ink on the ink work situated above and
simultaneously inks the composition, the form being placed in a corresponding
position beside the ink distributing plate. To allow the ink to be intensely rubbed,
the said plate consists of a revoluble metal disc having teeth on its periphery, into
which catches, on the return movement of the slide, an elastic hook provided on one
of the ink roller bearings, whereby the inking plate is revolved for about
30 to 40 degrees; another elastic hook, which is in constant contact with the
periphery of the disc prevents the latter from being turned back. An angle piece
having in its upper more or less horizontal arm the bearing for the ink plate and at
the lower end of the lower arm elastic rails for guiding the card to be printed, is
vertically adjustable behind the inking work by means of screws or in any other
suitable manner. Immediately behind said angle piece, the cards (about a hundred
in a block) are placed on the working table and laterally and rearwardly held in
the block by means of horizontally adjustable angle pieces. The position of the
composition is adjustable by screws, and form and matter are held up by aid of a
spiral spring surrounding a vertical beam, to which the form is attached, while the
form is lowered for printing by cam pressure from the main shaft, with a crank of
which the slide is connected, or in any other suitable manner.
The machine works as follows:
The card block is adjusted as described and the angle pieces are correspondingly
adjusted and fixed; subsequently the catchers are adjusted corresponding to the
thickness of the card and the angle piece carrying the ink disc is so far removed by
means of its set screws from the working table as to allow precisely one card to pass
through the interstice thereby produced. After the form i.e. the composition has
been correspondingly adjusted, the main shaft is revolved by means of a handle or
otherwise. Thereby the slide is advanced and the composition inked, while
the catchers pass the lowermost card through underneath the angle piece and guided
by the guide rails under the composition, where the printing immediately takes
place.

Improvements in Platen Presses for Printing Cards and such like.
I, JOHANN SEBASTIAN HERBST of Munich, in the Kingdom of Bavaria,
Empire of Germany, 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 :-
The object of this invention is an improved platen press for printing cards and
the like in a most simple manner without the necessity of laying in and taking out
each single card.
Referring to the accompanying drawing
Fig. 1 is a vertical section along line A, B, Fig. 2, and
Fig. 2 a plan of the improved platen press, which is actuated from the
main shaft w.
a is the platen or working table, the form with the type, c the inking work;
d is a slide connected with the crank of the main shaft as shown in Fig. 1
and adapted to be moved in the guiding e arranged underneath the working table
and having catchers -two of which are shewn as employed in the drawing-
vertically adjustable by set screws and elastically lodged in corresponding guide
pins. These catchers, according to the thickness of the card to be printed, project
over the working table through slots thercof. Slide carries also the ink
roller i lodged elastically in angle projections and adapted to distribute the ink on
the inking work by the reciprocating movement of the slide and at the same time
to ink-in the composition. Figs. 1 and 2 show both extreme positions of the slide
and of the ink roller. In order to cause the rubbing or distribution of the ink to be
as intense as possible, the inking work consisting of a metal disc e revoluble about k
is provided on its periphery with teeth, into which catches the elastic hook m on
the return movement of the slide, said hook being secured to one of the ink roller
bearings, thereby effecting a turning of the ink work for about 30 to 40 degrees.
To prevent the ink disc from being turned back on the forward movement of the
slide, another spring is so provided as to constantly engage with the teeth of the
disc. A. bridge, o provided in the rear of the inking work is adjustable by screw p
and carries the adjusting rail g. Said bridge carries at the top the bearing for the
inking disc and at the bottom the elastic rails for guiding the card to be
printed.

Immediately behind the bridge, the cards-about a hundred in a block-are
placed on the working table and held laterally and rearwardly in the block by
adjustable angle pieces s. The form. with the matter,-composition boxes of any
size may be screwed to the form-the position of which can be regulated by means
of screws t, is held in the position Fig. 1. by spring force or in any other suitable
manner and moved downward for printing by means of an eccentric fitted on
the main shaft as may be seen from Fig. 1. or of any other equivalent device, the
printing being effected in the manner hereafter described.
The improved machine works as follows:
The card block is laid in as described above and the angles s are correspondingly
adjusted and fixed in their position. Subsequently the catchers are adjusted
according to the thickness of the cards and the adjusting rail g is so far removed
by screw p from the working table, that just one card can pass through the
interstice thereby produced.
After correspondingly regulating the form or the composition, the main shaft is
revolved by means of hand crank or in any other suitable manner. Thereby the
slide is guided forward from position Fig. 1 into position Fig. 2. The matter is
consequently inked in and the catchers pass the lowermost card through underneath
the bridge o forwardly, said cards being guided by the rails r. The card when
arrived at the end of its movement, lies direct under the composition, and the

page_text: printing takes place immediately. The slide moves back again, the inking disc is
turned and on the next revolution of the shaft the operation is repeated by
the lowest card of the block being guided forward under the matter, while the card
which is already printed and is still lying at this place, is shifted forward so as to
fall down on table e. The catchers are slanted conically in the rear so as to be
allowed to evade the card block on the return movement of the slide that is to say
to shift the same slightly upward, whereby a sticking together of the lowermost
cards is obviated.
The improved machine can be operated by any inexperienced person and meets
a want generally felt by printers, paper dealers and others.
Having now particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, I declare that what
I claim is :-
An improvement in platen presses for printing cards and the like consisting in an
arrangement whereby the lowermost card of the card block, which is held by an
adjusting rail vertically displaceable in accordance with the thickness of the card
and by horizontally adjustable angle pieces s, is guided under the composition by
means of vertically adjustable catchers of a reciprocating slide d, while the
distribution of the ink and the inking-in of the matter is effected by means of an
ink roller lodged in angle projections of the slide, substantially as and for the
purpose set forth.
Dated this 15th day of April 1891.
