COMPLETE SPECIFICATION
I, HUGO LEWINSOHN of Bromberg in the Province of Posen and Kingdom of
Prussia, Engineer, 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 machines such as are used in printing addresses
on envelopes wrappers parcels and for other like purposes.
I will describe my Invention with reference to the accompanying drawings in
which Fig. I is a sectional elevation and Fig. 2 a plan of a printing machine constructed
according to these Improvements. Figs. 3, 4, 5 and 6 are details.
Upon the stand or frame a there is mounted the angular lever b which is connected
to the platen d by means of the link c. I do not limit myself however to the lever b
as this may be replaced by an excentric connected by a rod or by the link to the
platen, or instead both of the lever and of the excentric, the platen may be provided
with a handle as indicated by dotted lines in Fig. I so that the platen may be operated
by hand instead of by the lever or excentric.
A spring e (Figs. 2, 5 and 6) is secured to the platen and has upon its free end
a hook e which is adjustable and which engages with the spiral segments (or
equivalent ratchet teeth) on the disc or wheel. By this arrangement, the recipro-
cations of the platen involve the rotation of the disc or wheel in the direction of the
arrow (Fig. 5).
The points of the teeth or spiral segments are so arranged that they coincide
with the angles of the roller i, and the number of the spiral segments or teeth is
determined by the number of angles on the roller.
The wheel or disc is mounted upon the same axis as the roller which may have
four or other suitable number of sides and each of the angles of which is furnished
with sharp points (Figs. 3 and 4) which engage with the strip or band upon which
the printing surfaces are mounted, and cause its rotation therewith.
The roller i drives a strip of cloth or a chain or a similar suitable band or strip a'
upon which the different stereotypes: blocks, rubber stamps or other printing
surfaces are secured at equal distances as may be governed by the dimensions of the
roller.
An ink or colour box is mounted on the framing of the machine from which the
ink or colour is led and applied to the printing surfaces by suitable distributing and
inking rollers as is well understood and as in ordinary printing machines.
The band or chain a upon which the printing surfaces are mounted, is rolled
upon the roller A whence it passes along the table or way o to the printing roller i
whence it passes under the table o, over the brushes p q rand thence to the roller B
upon which it is wound after printing.
The rotary brushes p q r serve to thoroughly cleanse the printing surfaces
immediately after use. For this purpose the brush p is revolved in the trough pl
which is supplied with an alkaline or similar or suitable cleansing solution, and the
brush qis rotated in the trough q' which is supplied with the water or rinsing liquid.
The rotary brush y revolves in the air and serves for drying the printing surfaces
after their washing.
On one side of the frame y there is mounted a plungers having a wedge shaped
end, and which is normally held in the position indicated in Fig. 1 by the spiral
spring. The end of the plungers is pushed forward at and by every siroke of the
platen d and with its bevelled edge lifts the lever u upon which the pawl z is carried.
The pawl is held down by the spring and gears into the ratchet wheel which is
thereby rotated through the space of one tooth for every stroke of the platen. On

page_text: the ratchet wheel shaft the inking roller is mounted, which by its motion, distributes
the ink to the roller m and hence to the working rollers n n¹.
The action of the machine is as follows,-If the front part of the lever b is lifted
upwards, the platen is drawn back by means of the link c; similarly when the excentric
is used, a half revolution of the excentric will also draw the platen back into the
position indicated in dotted lines Fig. 1. The same result may of course be obtained
by pushing the platen back by hand.
The springe is thus operated to turn the roller into the next position by its hook
engaging with the spiral segments or teeth on the wheel or disc f. As the points k
en the angles of the roller engage with the strip or baad on which the printing surfaces
are mounted, they cause it to move therewith, so that for every movement of the platen
a new printing surface is brought into position. At the same time a new printing
surface is also brought under the operation of the inking rollers and . The paper
or article to be printed upon is inserted between the platen and the printing surface on
the roller i. or it may be held upon the platen during the process of printing in the
usual manner.
扎
When a chain or chains is or are used instead of the band or strip for carrying the
printing surfaces, the points are arranged to gear into the links of the chain.
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 machine for printing by means of a series of printing surfaces arranged in
succession upon a strip chain, or band, constructed arranged and operated substantially
as hereinbefore described and as illustrated by the accompanying drawings..
(2) In a printing machine for printing from successive surfaces, the combination
and arrangement of a strip band or chain upon which the printing surfaces are secured.
a square or polygonal printing roller, a supporting table or type-way, distributing and
inking rollers, cleaning brushes, a platen, means for rotating the printing roller by the
motion of the platen and consisting of a toothed or segment wheel and a catch.
and two rollers upon which the printing surfaces are wound before and after
printing substantiallyas hereinbefore described and as illustrated bythe accompanying
drawings.
(3) In a printing machine for printing from successive surfaces, the combination
and arrangement of a band strip or chain upon which the printing surfaces are
mounted, a roller over which the printing surfaces are successively passed and upon
which the printing is effected, and the two rollers upon which the printing surfaces are
wound before and after printing; substantially as hereinbefore described and as
illustrated by the accompanying drawings.
(4) In a printing machine for printing from successive surfaces. the combination
and arrangement with the platen, of a spring carrying an adjustable catch, and a
ratchet wheel or disc having segments of spirals thereon, substantially as and for the
purpose hereinbefore described and as illustrated by the accompanying drawings.
(5) In a printing machine for printing from successive surfaces, the combination
and arrangement of the rotary brushes and troughs substantiallyas and for the purpose
hereinbefore described and as illustrated by the accompanying drawings.
Dated this 17th day of December A.D. 1889.
