Improvements in Apparatus for Dyeing or Scouring Yarn.
I, CHARLES LEOPOLD KLAUDER, of City and County of Philadelphia, and State
of Pennsylvania United States of America, Dyer 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:
My invention relates to machines for dyeing or scouring yarns; and consists of
certain improvements which are fully set forth in the following specification and shown
in the accompanying drawings which form part thereof.
The object of my invention is to accomplish in a simple and inexpensive manner
what has heretofore been done by hand in a very laborious process and to this end my
invention consists of certain improvements upon the dyeing or scouring machine
exhibited in my English patent No. 8803 dated June 18th 1887. In that machine
the yarn is supported upon transverse bars in a suitable frame or wheel which is
adapted to rotate to move the yarn into and out of the dye liquor, and to insure all
portions of the yarn being treated alike, one at least of the transverse bars is caused
In order to suit the
to rotate slowly and thereby shift the position of the yarn.
supporting bars to skeins of different lengths it is necessary that they be made
adjustable to or from each other. To accomplish this more easily and simply and also
to more readily produce the desired rotation of the transverse support or bar to shift
the position of the yarn this invention is particularly intended, as well as embodying
certain other improvements hereinafter set out. It not infrequently happens that the
yarn becomes caught in this rotating mechanism, or through some other accident the
rotation of the transverse bar or support is not accomplished and the yarn shifted. By
my improvements herein set out, when this occurs, an alarm is sounded so that the
attention of the operator is directed to the machine and he may at once correct the
fault.
These and other improvements are more fully set forth and disclosed in the descrip-
tion and of the drawings.

and
Figure 5 is a perspective view of the mechanism for rotating the transverse bar and
the alarm detached from the machine.
A is the main body or casing of the machine the lower portion of which constitutes
the dye vat and contains the liquor.
Journalled in this vat is an axle C to which are secured two wheels or lateral
frames B B having the arms b and the central or disc portions D. Supported by and
between these frames are the transverse bars or rollers E and F preferably arranged
in two series and concentric with the axle (. The outer series of rollers or transverse
bars E are preferably polygonal in shape, so as to more readily move the yarn which
is stretched upon thein." The ends of these bars E are made with journals e, e¹,
which fit into the frame B. Loosely journalled in the frame B are the ratchet G
and star wheel H preferably arranged on opposite faces of one side of the frame B,
and connected so that a turning of the star wheel H will produce a similar turning
of the ratchet G. In this ratchet G is journalled the end e of the bar E, so that
a turning of the star wheel H will turn the bar E. The journalled ends e¹ of the
bars E fit in the opposite side of the frame B. To insert these bars into the frame
the journal or ende is first thrust into the bearing adapted to receive it in the
frame B and the bar is moved until the journal or end e comes within its bearing
in the ratchet G when it is shifted into the position shown in Figure 3. By this
means the bar may be easily removed for the purpose of changing the skeins of
yarn. As however I prefer to construct my machine closed as shown, it is necessary
to provide doors J and K in the upper half of the machine located in the line of
travel of the ends of the bars or supports to allow room for their removal in the
manner above described. It is also apparent that the particular location of the star
wheel H and ratchet G may be varied from that shown; nor is it necessary that
the star wheels H be used at all, though I prefer this construction; but in place
thereof pins or projections upon the transverse bars E, similar to those shown in letters
patent No. 8803, might be used in connection with the pivoted spring stop O hereafter
described (see dotted lines Figure 3).
The inner set of bars F is also provided with journals fand f¹ by which they are
inserted in the bearings d on the disc portions D; and to readily accomplish the
adjustment of these bars to or from the bars E to suit the skeins of different lengths,
I provide the disc portions D of the frames B with concentric series of these bearings d,
so that by changing the bars F from one set of bearings to another the distance from
the bars E may be increased or diminished as desired. These bars F are inserted and
removed in a manner similar to the bars E with the assistance of the door K. Ordi-
narily the bars E and F cannot be removed or become loosened from the frames B, one
side of which is located near the side of the main casing A which acts as a guide for
the bars and does not give sufficient space for them to work loose or be removed
except through the agency of the doors J and K. L is a guide plate which may be
secured on the upper portion of the interior of the main casing A to guide the ends of
the bars E in their rotation out of the dye liquor. Mare pawls pivoted on the frame B
and adapted to engage in the ratchets G to prevent the turning of the star wheels H
and the transverse bars E in the opposite or backward direction. N are springs
attached to these pawls to force them normally against the ratchets G, O is a pivoted
stop in the main casing A immediately above the frame B and in the path of the star
wheels H, the projections of which come in contact with it. Attached to this stop is
a spring P which normally holds the stop in position but allows it to be moved or
pushed by the projections of the star wheel H to prevent breakage if by any means
the wheel is caught and cannot rotate. A lug upon the base of the stop prevents the
spring drawing it out of the line of the star wheel projections. P' is an adjusting
screw by which the tension of the spring may be regulated. Extending from the
pivoted stop O is an arm o having a connection with a bell Q, so that when the stop O
is moved the arm or extension o being also moved operates the bell hammer to sound
the alarm and indicates that the bar E has not rotated. While prefer a bell or

page_text: gong such as shown for this purpose it is apparent that any other suitable means might
be used operated by the pivoted stop O to indicate the failure of a transverse bar E to
rotate without in any way departing from my invention. It will be seen that as the
frame B rotates, each of the bars E in turn comes under the stop O, and the projec-
tions of the star wheel coming in contact with the stop will be rotated, so that these
bars E will have an intermittent rotation during their travel around the axis C. If
however the yarn becomes tangled so as to prevent the rotation of the bar E, when
the projection of the star wheel H comes in contact with the stop O, it will not be
rotated by it but will overcome the tension of the spring O and push over or past the
stop thereby sounding the aların as heretofore stated. The operator may then open
the door in the front of the machine and observing the fault, may stop the rotation of
the skein carrying frame B and correct it.
The rotation of this frame B is accomplished by a worm and worm wheel gearing R,
or by any other suitable means. To prevent the yarn slipping to the ends of the
bars E and F and thus becoming tangled with them and preventing their rotation,
circular guides S may be secured on the inner sides of the frames B.
T is a tank for the dye liquor provided with a valve t, and leading into the dye vat
through a pipe U whoreby the liquor is introduced. V is a steam pipe which may be
arranged at the bottom of the tank or vat to heat the liquor by forcing steam through
it. A pipe W having a valve w may also be used opening into the pipe U through
which steam or air may be blown into the vat with the dye liquor from the tank T.
I do not limit myself to the mere details of construction which are hero shown as
they may be modified in many ways.
