I, WILLIAM LLOYD WISE of No. 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Chartered Patent Agent, do hereby declare the
nature of this invention to be as follows:-
The apparatus heretofore employed for printing warps has been suitable only for
printing warps of a certain definite length. Consequently in order to print warps
of different lengths it has been necessary to employ a number of apparatus gach
suited for some particular length of warp.
Now this invention has reference to a method of and apparatus whereby warps
of any desired length of thread and of any length of repeated design can be
printed upon printing tables. For this purpose an apparatus is used in which the
arrangement of the warp rollers with relation to the printing table, as also any
required alteration in the distance of the guide rollers from one another, can be
easily and quickly varied to suit requirement.
In the accompanying drawings,
Fig. 1 is a sectional side elevation ;
Fig. 2 a horizontal section; and
Fig. 3 an end elevation of apparatus according to this invention.
The apparatus comprises a framework to each of the two long side frames M' M² of
which there are attached internally, at top and bottom rails n. Upon each of the
top rails there are mounted six sliding or adjustable bearings and upon each of
the bottom rails there are mounted two similar adjustable bearings l. In the upper
bearings are journalled the rollers e³, c², ƒ³, ƒ³, 1³, and in the lower bearings
the rollers e' . and are also adjustable bearings; they are suspended from
the

Method of and Apparatus for Printing Warps.
A. communication from the BROTHERS WIEDE, of Alt-Chemnitz, Saxony, Germany,
Manufacturers.
I, WILLIAM LLOYD WISE, of No. 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Chartered Patent Agent, 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 stateinent :-
Warps for use in the manufacture of figured goods of a certain definite length
as for example carpets, have heretofore been printed in apparatus the construction
of which has been suitable only for receiving warp threads having a certain
definite length. Consequently in order to print warps of different lengths it has
been necessary to employ a number of apparatus each suited for some particular
length of warp, unless the circumference of the apparatus (roller) be a multiple of
the length of warp to be printed.
Now this invention has reference to apparatus whereby warps of any desired
length of thread and of any length of repeated design can be printed upon printing
tables. For this purpose apparatus is used in which the arrangement of the warp
rollers with relation to the printing 'tables as also any required alteration in the
distance of the guide rollers from one another can be easily and quickly varied to
suit requirement.
In the drawings filed with my Provisional Specification,
Fig. 1 is a sectional side elevation illustrating one construction of apparatus
according to this invention.
Fig. 2 is a horizontal section thereof showing the printing table in 'plan; and
Fig. 3 is an end elevation of the apparatus.
Figs. 4, 5 and 6 of the accompanying drawings are corresponding views to
Figs. 1, 2 and 3 respectively illustrating a modified construction.
The apparatus shown in Figs. 1, 2 and 3 comprises a framework, to each of the
two side frames m', m² of which rails n are attached internally at top and bottom.
Upon each of the top rails are mounted any suitable number say six or more
sliding or adjustable bearings and upon each of the bottom rails are mounted
two similar adjustable bearings in the upper bearings are journalled the
rollers effff, and in the lower bearings the rollers e, eh and h² are also
adjustable bearings; they are suspended from the upper rails n and serve to carry
the rollers g' and g² respectively.
The upper parts of the frames are stiffened by means of tie rods o and struts
or screws P. The warp passes from a roller a through the brake device c to the
thread guided whence it is led under the rollers e and and then over the
rollers f³, f^, e, and is firmly connected to the next portion of warp about
to pass under the roller e'. This roller e' is provided with a crank g and actuates
the other rollers e², e³, eª, ƒ³, ƒºº, ƒ'³, ƒ¼, by means of a belt k, whilst the rollers g
are actuated from the rollers e et by belts t. After this beaming the warp'hanks
they are pressed by the thread clamps upon the stuffed table and are printed by
means of the printing devices the width and length of which correspond to the
scale s.
The modified construction of apparatus shown in Figs. 4,5 and 6 offers the
advantage of requiring less labour on the part of an attendant as, owing to there
being no frames at the outer sides of the apparatus the finished printed hanks can
be readily removed by simply withdrawing them from the rollers, the open side of
the apparatus admitting of the hanks being at once set free upon lifting for this
purpose the two lower rollers from their bearings and turning them inside by
means of the movable suspended bearings.
This apparatus can with advantage be provided with guide ribbons to which the

page_text: front ends of the threads are fastened; the latter are thus effectually guided as
the guide ribbons are moved by suitable means from one side to the other. In
this modified construction of apparatus the side frames m² m² shown in Figs. 1, 2.
and 3 are replaced by columns m³, m², m³, m of suitable height arranged
above the centre line of the printing table and the number of which will depend
upon the length of the apparatus. On these columns are mounted vertically
adjustable or sliding brackets / carrying as in the former construction, the upper
rollers ee etc. To the columns and also to the long sides of the printing table
are fastened preferably by means of screws y rails carrying the longitudinally
adjustable suspended bearings and the upright bearings P
The crank g of the construction, shown in Figs. 1, 2 and 3 is replaced by a fly
wheel actuated by a crank pin and rod q from a treadle not shown. For
beaming the warp threads b, guide ribbons are arranged around the rollers
and to which the said threads are fastened.
A slowly revolving screw spindle actuated from the roller e¹ by means of a
crank disc y and connecting rod y' serves to gradually displace the guide ribbons
on the rollers e e etc. during the rotation of the rollers, so that the threads
cannot run one upon the other.
According as a greater or smaller multiple of the length of the repeated
design is to be printed, one or more warps are beamed one near the other over
the printing table and simultaneously printed. There are shewn for instance in the
accompanying drawings three hanks of warp b¹³. A scales fixed on the
printing table is arranged between them.
The length of the repeated design is determined by one passage of the thread
over all the rollers. It is obvious that within given sizes of the frame this length
of the repeated design may be easily and considerably modified by suitably
adjusting the rollers in relation to each other. By means of the same printing table
yarn for measured goods of very different length can therefore be printed, as not only
the whole height above the printing table, but also by suitably lengthening the
rails the length of warp between the rollers el e' can be made greater than the
length of the printing table.
The printing takes place between the thread clamps u the distance apart of
which is set by the scale. The printing is effected not in single lines as is the case
when printing wheels are used, but as far as possible across the whole width of the
same color, in many cases up to a width which is 30 or 40 times that of the line
that can be printed with printing wheels.
In order to protect the rollers and consequently the following portion of the
bank from being soiled by colors from the freshly printed portion of the hank,
a protecting apron i (Fig. 1) passes from the roller g' under the warp and around
the other rollers to the roller g. During the beaming operation the mechanism
for actuating the protecting apron may be put out of gear.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
1. The herein described method of printing upon an ordinary printing table,
hanks of warp threads for figured goods of different lengths of thread or
repeated design by means of printing devices of different width or length, which
consists in passing the said threads above the table around guide rollers the
distance apart of which can be adjusted to correspond to the length of repeated
design to be printed substantially as described.
2. Apparatus for printing warp threads in which thread rollers (e' e³) between
which the hank is pressed down by clamps u upon the printing table and also
other rollers e e e and guide rollers (Fig. 1) are mounted in adjustable or
sliding bearings that are movable upon rails nn fastened on the side frame of
the apparatus (see Figs. 1-3) or in the brackets of a column frame open on both
sides (as illustrated in Figs. 4 to 6) so that these rollers together with the rollers g

page_text: for the protecting apron can be adjusted in relation to each other to an extent
corresponding to the length of the repeated design to be printed substantially as
described and shown.
