Complete Specification Accepted, 31st Aug., 1888
I, THEODOR REINER of 1 Parkstrasse, Leipzig, in the Kingdom of Saxony, Manu-
facturer, do hereby declare the nature of my invention to be as follows:
This invention relates to printing of manifold copies of a manuscript drawing or
the like made in suitable ink and transferred to a surface from which copies may
be printed.
The improvements consist in arranging two cylinders of zinc or other convenient
material so that they or one of them may act as receiving surfaces for the writing or
the like of the original according as the writing etc., is on both sides or on one side
only of the original, such rollers also operating with pressure to feed the paper or the
like to be printed and to imprint the writing, design or the like on the same."
Each said roller is provided with a roller, feeding matters for causing the adherence
of the transfer ink of the original to the rollers, and also a series of rollers for trans-
ferring ink or color from a perforated or other ink or color roller to the negative on
the printing roller when printing from the same.
A crank handle is provided for operating one of the rollers, the others being either
driven by friction or mechanical gearing.
If a continuous band or roll of paper or the like is to be printed in the press, a
roller may be provided to feed the paper to the press.

page_text: I THEODOR REINER of 1 Parkstrasse Leipzig in the Kingdom of Saxony Manu-
facturer 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 printing of manifold copies of a manuscript, drawing
or the like made in suitable ink and transferred to a surface from which copies may
be printed.
The improvements consist in arranging in a machine for this purpose two cylinders
of zinc or of any other convenient material having a suitable surface formed as herein-
after set forth or otherwise, so that said cylinders or one of them may act as receiving
surfaces for the writing or the like of the original according as the writing etc. is on
both sides or on one side only of the original, such cylinders also operating with
pressure to feed the paper or the like to be printed and to imprint the writing, design,
or the like on the same.
Each said cylinder is provided with a roller feeding matters for causing the adherence
of the transfer ink of the original to the cylinders and also a series of rollers for
transferring ink or colour from a perforated or other ink or colour roller to the negative
on the printing roller when printing from the same.
A crank handle is provided for operating one of the rollers the others being either
driven by friction or mechanical gearing.
If a continuous band or roll of paper or the like is to be printed in the press, a
roller may be provided to feed the paper to the press.
Referring to the accompanying drawings: Fig. 1 is a vertical cross section of the
improved machine, Fig. 2 is a plan and Fig. 3 a cross section of the ink trough.
The cylinders A A' are of equal size. I prefer to use cylinders of metal, glass,
earthenware or other suitable material and provide them with a surface composed of a
mixture of the following substances in the proportions given or thereabouts.

page_text: The ink trough K consists of two parts or halves adapted to be approached to each
other by the screw S so that the width of the slit between them may be adjusted.
By screwing down the screw L on the cover D the ink is pressed through the
slit in the bottom of the trough onto the roller fand thence to the rollers g, t and c.
Over the roller t is situated the roller i having a rotary and longitudinal back and
forth movement effected by a cam and spring or other suitable mechanism so that the
roller disperses the ink on the roller t. The whole inking mechanism may be thrown
in or out of action by the lever operating on a sliding frame in which the rollers
fgte and trough K are supported.
Where only one cylinder is to be used for printing, there may be provided a feed
apron m which passes between the cylinders A, A, and over the rollers
The operation is as follows:
The cylinder A is cleaned with common turpentine, and water and a clean cloth and
polished with a few drops of magnesium chlorate. The inking mechanism is set out
of action. The manuscript written with autographic ink and moistened on the under
side is, if written on one side only, put on a thin pasteboard or sheet with the written
page uppermost and introduced between the cylinders.
By turning the crank handle in one of the cylinders the paper is turned round with
the cylinder and may be taken off after repeated turning and moistening.
Thereupon the transfer on the cylinder being allowed to dry for about five minutes
the cylinder is covered with any suitable preparation preventing the printing ink from
adhering to uncovered places of the transfer. The inking mechanism is brought into
action and the printing is begun.
The artificial lithographic surface before mentioned has the considerable advantage
of not being porous like lithographic stone although suitable to receive lithographic
writing.
The printing ink and negative may be removed by common turpentine, water, and
magnesium chlorate and the cylinders made suitable to receive another negative.
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 1
claim is.
1. In autocopying printing presses the combination of two cylinders A A', adapted
to receive the negative and print therefrom substantially as set forth.
2. In combination with the cylinders A A' the lithographic surface, consisting of a
mixture of soluble glass, whitning calcium carbonate, magnesium carbonate silicate of
magnesia, glycerine, water, oxalic acid, manganese ore and mineral colour substantially
in the proportions set forth.
3. In combination with the cylinder or cylinders A A' an ink trough consisting of
two paris separated by a slit, having a screw for regulating said slit, a cover D and a
screw or screws L for depressing said cover substantially as set forth.
