An Improved Typographic Printing and Cutting Machine.
I, HERMANN SCHWARZ of 8 Herrengasse Prague in the Austrian Empire,
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 machines for printing. labels, vignettes or patterns upon
strips of paper and cutting the printed labels or tickets to the desired shape
and size.
In the annexed drawings the improved machine is illustrated in side elevation in
Figure 1; and in end elevation in Figure 2. Figure 3 is a longitudinal section
through the printing apparatus; Figures 4 and 5 illustrate respectively a front view
and a plan of the apparatus and Figures 6 and 7 shew details of the cutting
rollers. Similar parts are indicated by similar letters of reference in the different
figures.
Referring to Figures 1 and 3 A is the printing apparatus consisting of printing
and blanket cylinders and inking and ink distributing rollers; B is the feeding
device, and shews the position of the cutting-off cylinders. All these are
operated simultaneously from a common wheel a which is driven from the crank
shaft e through the wheels bc d. The crank shaft e is connected to the treadle
by the pitman or connecting rod f.
The paper feeding arrangement consists of two iron rollers k¹ geared together
by means of the two wheels the lower. one of which is driven by the wheel a.
The two rollers may be adjusted relatively to each other by the screws i. An endless
band m travels over the table h, passing through the slot o and around the rollers n
and k, the roller n being movable so that the tension of the band may be adjusted.
This band serves to introduce the paper between the feeding rollers k k².
In the printing apparatus shewn fully in Figure 3 p is the ink or colour box
arranged in such a manner within the casing p¹ that its position can be adjusted by
the screw p². The ink is taken from the box by the roller q whence it is inter-
mittently transmitted by the roller q' through the rollers q² q³ q to the upper printing
cylinder r. The printing cylinder and the blanket cylinder are geared together
by toothed wheels s and s¹ and are rotated by the wheel a. The distributing roller g¹
is mounted on the end of a counter-weighted lever u pivoted at 3 and free to move so
that the roller may be brought into contact either with the inking roller q or with
the roller g².

The motion of the lever is obtained by a disc cam t which is mounted upon the
inking roller shaft and is rotated by means of a band or cord from the shaft of the
wheel a. The shaft 2 of the distributing roller is furnished with a bowl t' which
engages with the outer rim of the cam t." When the cut-away portion of the cam is
opposite the bowl t' the counter-weight on the lever brings the distributing roller q¹
into contact with the inking roller q, until the further revolution of the cam brings
the circular part of its circumference into contact with the bowl t' and forces the
distributing roller away from the inking roller and into contact with roller q².
The device for cutting off the labels or tickets consists of two rollers v and v¹ geared
together by wheels w and w¹ and driven by the common wheel a.
These rollers are
shewn in detail in Figures 6 and 7. The cutter roller v' is furnished with a number
of curved knives ² of any desired shape and in some cases a knife or punch ³ is
carried in addition for cutting holes in the labels for attachment to parcels. In these
latter cases the roller is hollowed as shewn at v¹ to allow of the escape of the removed
portion of paper or pasteboard.
The distances of the printing roller and the cutting roller from the respective
Jo

page_text: lower rollers may be accurately adjusted by the screws 23. The printing roller and
the cutting roller are of equal diameters and, being driven from the cominon wheel a
revolve at equal speeds so that the labels are cut off accurately and in proper
succession. The ordinary devices may be applied for ensuring the adjustment of the
ink or colour distributing rollers.
When the machine is in operation the strips of paper or pasteboard which may be
of any length, are placed upon the table and are carried by the band m to the
feeding rollers k k¹. The strips are fed forward by these rollers to the printing
rollers and after being printed are passed on to the cutting rollers.
By the addition of further printing and inking or colouring rollers labels can be
printed in several different colours.
The knives are fixed upon the roller by means of plates v. These plates have
inclined edges which bear against the inclined sides of the knives and are held securely
in place by screws. By these means the knives are firmly held without interference
with their edges.
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 and simultaneously cutting labels, tickets and similar
articles from continuous lengths of paper, constructed arranged and operated
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
(2) In a machine for printing and cutting labels and tickets simultaneously from
continuous lengths of paper the construction and arrangement of the endless web or
band m, operating substantially as and for the purpose herein before described and as
illustrated by the accompanying drawings.
(3) In a machine for printing and cutting labels and tickets simultaneously from
continuous lengths of paper, the combination and arrangement of the distributing
roller q the weighted lever u¹, the ink duct roller q, and the cam t; substantially as
herein before described and as illustrated by the accompanying drawings.
(4) In a machine for printing and cutting labels and tickets simultaneously from
continuous lengths of paper, the construction combination and arrangement of the
hollow roller with the circular knives v2, substantially as and for the purpose herein-
before described and as illustrated by the accompanying drawings.
(5) In a machine for printing and cutting labels and tickets simultaneously
from continuous lengths of paper the construction and arrangement of the knives and
holding plates upon the hollow roller v¹; substantially as herein before described and
as illustrated by the accompanying drawings.
Dated this 22nd day of August A.D. 1890.
