Improvements in Printing Machines for Yarn or Warp Threads.
.
I, CARL BAREUTHER, of 5, Theaterplatz, Eger, in the Kingdom of Bohemia,
and Empire of Austria, Carpet Manufacturer, do hereby déclare 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:-
+
Yarn for the manufacture of carpets, figured plush, velvet covers is printed
on printing drums, the periphery of which depends on the design, length of
pieces &c., of the fabric which is to be produced.
For instance a printing drum on which is to be printed yarn of a carpet
3 meters long requires a larger periphery than that on which a shorter piece is
to be treated; or, when the pieces are longer, yarn of greater length and there-
fore drums of greater periphery, are required. Further the periphery depends
also upon the binding and character of the fabric to be made and upon other
circumstances.
Thus a point is reached when the periphery of the printing drum becomes
impracticable, or at least a matter of difficulty.
This invention permits of the printing of small quantities, and of yarn of any
length up to 40 meters and more. The machine does not require a very large
room, it simplifies the operation, and many parts of the old kind of machine' may
be used.
In order that this invention may be the better understood I now proceed to
describe a form of construction of the machine, reference being had to the accom-
panying drawings and to the letters and figures marked thereon.
Figure 1 is a side view.
Figure 2 is a plan.
Figure 3 is a diagrammatic side view.
Figure 4 shows the mechanism for operating the printing carriage, on
section A-B, of Figure 1, in the direction of the arrow.

thread.
Figure 6 shows the arrangement for transferring patterns to the yarn and a
front view of the guide for the thread. Figure 7 is a plan of Figure 6:
This machine consists:-Of a fixed frame I with working stand and the driving
device for all parts, of a frame II, running on rails 53 and having a winding
apparatus for its operation, and of a fixed frame III with colour carriage 20 and
printing device 45.
On the frame I, Figures 1 and 2, is the driving roller 1, on the frame II is the
driven roller 2. Over both rollers. 1 and 2 passes the endless band or cover 3
which forms the periphery of the machine.
4 and 5 are the axles of the rollers 1 and 2. In order to secure the even
rotation of the same an axle 10 is arranged beside the frame of the machine,
and driven by a pair of bevil wheels 6, 7. This motion is transmitted to the
bevil wheels 9, 8 and therefore to the axle 5.
The main axle 4¹, situated on the frame, drives all parts of the machine; it

page_text: approaches the main axle 4. The frame II remains in its position, like the
frame I, unless the change of pattern or other cause does not require a change of
periphery.
For short lengths of yarn or warp the fixed frame may be arranged so that the
central frame is dispensed with.
The relations between the patterns and the movements of the band or cover 3
is as follows:
As no toothed rim can be attached to the support of the yarn warp to actuate
a counting device direct each division of the warp or of the circumference is
rendered visible by special mechanism by which each advance of the rollers 1
and 2 is indicated on the counting or division discs 36, 37 (Figs. 2, 6 and 7.)
The counting mechanism can be operated in the reverse direction by the hand
wheel 35 fixed to the axle 34 from which is operated the axle 33 through bevil
wheels 60. On the end of this axle is situated the small cog wheel 32, which
engages with the cogged rim 31 of the roller 1, at a ratio of 1:10., so that when
the wheel 32 has been rotated 10 times the warp or yarn is moved about 2 meters
on the cover or band 3. On the axle 33 is also situated a cog wheel 72 which
operates by the wheel 73, and the wheel 75 connected to the bevil wheel 74, the
bevel wheel 76 and the axle 61, connected thereto, at a ratio of 1:5, so that this
axle is rotated twice, or once per meter of warp during one rotation of the roller 1.
The axle 61, by gearing 77, 38, 78 which can be changed as desired by change
wheels, operates the first counting disc 36, which has divisions from 1-100;
from the latter is operated the second counting disc 37 by the bevil wheels_79
and 80 and the axle 81 and worm 82; the disc 37 indicates hundreds.
instance if it were desired to print a warp 20 meters long, with a division of 120
strips of colour per meter, the change wheel ratio will be 6:5; otherwise the
ratio may be changed as required.
The operation of the machine is as follows:-
For
The desired circumference of the yarn or warp is produced by the movable
frame II which is then fixed by screws. Over the two rollers 1 and 2, and 51,
51, is stretched the band like cover 3 which is about 30 cm. wide. On the cover 3
is conveniently arranged a cover of paper or oil cloth. The yarn or warp to be
printed is wound as is usual from a bobbin frame to the device 3, by belt driving
In the case of very long warps, the yarn is tied lightly by a few threads to the
movable support 3, to prevent the threads hanging down after printing. The
operator who prints according to pattern or numbers finds on the counting discs 36
and 37 the number corresponding to the pattern, adjusts the apparatus for print-
ing the strip and prints colour after colour, according to the pattern, until the
warp is complete. When the warp has been printed it is taken from the machine,
the binding threads before mentioned having been previously loosened, if used.
The circumference is then reduced by the device 54 and the cover is loosened. In
the case of very long warps one or more light frames with guiding rollers, like 51,
Figure 3, are arranged between the frames III and II to give more support to the
warp; these frames must be attended to by helpers when the warp is taken off.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1st. A machine for printing yarn or warp, having a variable periphery, in
which the yarn or warp to be printed is moved on a movable support 3 in end-
less form, placed over two rollers 1 and 2, adjustable as to the distance between
them, one of which rests in a movable frame II, the yarn or warp being fed to a
printing device where it is printed with strips of colour, substantially as described.
2nd. In a machine as claimed in Claim 1 the transmission of the division of
the periphery to a counting device, according to which the printing is done, sub-
stantially as described.
3rd. In a machine as claimed in Claims 1 and 2 the arrangement of a seg-
