COMPLETE SPECIFICATION.
Improvements in the Manufacture of Knitted Figured Pile Fabrics
and in Warp Frames therefor.
I, ERNST SAUPE, of 29 Carlstrasse, Limbach, Saxony, in the Empire of Germany,
Engineer, do hereby declare the nature of my said invention and in what manner
the same is to he performed, to be particularly described and ascertained in and
by the following statement :-
The object of my invention is to affect improvements in the manufacture of figured
pile fabrics, and in the construction of warp frames for effecting the same.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts; and in which drawings only the most essential
parts of the warp frame are shown.
Fig. 1 illustrates the general arrangement of my invention.
Figs. 2, 3, 4 and 5 illustrate the action of the same.
Fig. 6 is an enlarged view of the needles n² with their frames and weights.
Fig. 7 is an elevation at right angles to Fig. 6.
Fig. 8 is a horizontal section on one of the lines
elevation showing the method of removing one or
necessary.
of Fig. 7, and Fig. 9 is an
more of the needles when
m m are two rectangular bars or holders fitted with needles m¹ m¹ each having a
small tongue or latch, n n are two other rectangular bars or holders fitted with needles,
having eyes, as shown. n³ n³ are two bars fitted with needles n², hereinafter called
plush yarn guides, and moving in parallel directions in the bars n³. The needles n²
not only follow, simultaneously, the motions of the needles n', which take up the yarn
for the ground work, but they are also actuated simultaneously or alternately by the
Jacquard machine arranged above the warp beams b b, so as to be raised or lowered by
the bands ss for the purpose of moving the needles n² out of reach of the tongued
needles m' m', which produce the ground work of the fabric; the movements being
shown in Figs. 2, 3, 4 and 5. "The plush yarn guides n² are arranged in their
fittings so that any irregularity which may at any time occur may be readily
removed. rare dovetailed slides which retain the guides n² in their places. The
slides are formed in short lengths, as shown in Figs. 7 and 9, in order that one or
more of the guides may be removed, when required, as shown at in Fig. 9.
The needles n² are loaded with weights e e cast thereon, in lieu of the ordinary spiral
springs hitherto used, to ensure the automatic descent of the needles.
a a are two guides for the tongue needles m' m', for producing the ground work,
while the needles or plush yarn guides n² form the plush by moving reciprocally
above the tongued needles m'. The needles or plush yarn guides n² are threaded
with yarn of various colors, as required, and are actuated alternately by the
Jacquard frame or machine, whereby figured patterns of various colors may be
produced.
The needles n' receive the yarn from the beams bb, and the plush yarn needles n²
work with the aid of spools or bobbins 1, the yarn from which is carried over
the rollers and rods w¹, w² and w³, whereby it is kept in a suitable state of
tension.
The motions of the frames cause one set of rollers w to remain at rest, while
the other set is in motion, and the foregoing arrangements secures the tension of
both sets of varn.

page_text: 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. The improvements in the manufacture of figured pile fabrics, and in machinery
or apparatus therefor, substantially as herein before described and illustrated by
the drawings.
2. In machinery or apparatus for the purposes aforesaid, the application and use
of two rows of movable needles n2 n2 guiding yarn of various colors through
corresponding holders n³ n³, the needles being operated independently and alternately
or simultaneously, by means of a Jacquard machine, such operations being effected
out of reach of the tongued needles m¹ m², producing the ground work, while the
needles n n follow, at the same time, the motion of the needles n' n¹, which guide
the yarn forming the ground work of the fabric, substantially as herein before described
and illustrated by the drawings.
3. In machinery or apparatus for the purposes aforesaid, the application and use of
weights e on the needles n for automatically operating the same, substantially as
herein before described and illustrated by the drawings.
4 In combination with apparatus as aforesaid, the application and use of
slides ",
for retaining the needles n' in their places and facilitating their removal,
when necessary, substantially as herein before described and illustrated by the
drawings.
5. In combination with apparatus as aforesaid, the arrangement of rollers w and
rods ww and w³, whereby the yarn is retained in a state of tension substantially as
herein before described and illustrated by the drawings.
