COMPLETE SPECIFICATION.
Improvements in the Construction of Machinery or Apparatus for
Stretching, Brushing, Opening and the like Treatment of Hanks
of Yarn.
}
We, JOSEPH SPENCER LORD and GEORGE SPENCER LORD, both of Victoria
Engineering Works, Whitefield, near Manchester, in the County of Lancaster,
Engineers, 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 an improvement in apparatus for stretching, opening,
and brushing hanks of yarn as they are taken from the sizing or dyeing machine
in a wet state, with the object of freeing the yarn from any superfluous size or
other extraneous matter, stretching and opening out the same, and preventing
entanglement in its subsequent treatment."
Our improved apparatus and the manner in which the operations hereinbefore
named are carried into practical effect will be readily understood on reference
to the accompanying sheet of drawings and as hereinafter described.
Fig. 1 is a front elevation and Fig. 2 is an end view showing our improve-
ments applied to a machine that is constructed in accordance with and as
described in the Specification No. 14,518 of 1898 except the stretching rollers
and brushes, the stretching and opening mechanism constituting the subject of
this our present invention. Figs. 3 and 4 are front and end views respectively
of our said improvement drawn to an enlarged scale.
In these views similar letters refer to similar parts.
The hanks of yarn have hitherto been placed over two stretching rollers super-
posed and at a certain distance apart; the wet yarn however does not freely
leave the bottom roller when the arm carrying the said bottom roller is lifted
to stretch the yarn. In order to obviate this we substitute for the ordinary
bottom stretching roller two horizontally placed rocking bars which are
permanently fixed in relative positions to each other by the end plates u² but
rock on a horizontal spindle or bar which forms a part of a swing frame n
that is carried by an oscillating shaft o. We place a brush w so as to act on
one side of the yarn such as has been customary and attach to the brush frame w¹
by means of studs v a spindle or bar q on which we place a circular opener
for opening and evening the yarn said opener preferably passing through the
hank of yarn and rising and falling, advancing or receding-simultaneously
with the brush. We form the aforesaid opener with grooves that by preference
extend spirally from the centre towards either end, but said grooves may be
formed at one angle only from end to end either right or left or may in some
cases be straight. The roller m is stationary in respect of position but has a
slow revolving motion imparted thereto; the grooved roller only revolves
on the spindle g when in contact with the yarn.
When the yarn is carried round the roller m in the direction indicated by
the arrows in Figs. 2 and 4, the adhesion of the yarn causes the bar u to be

page_text: raised thereby deflecting the bar until the tension on the spring that is
connected to the bar as shown or an equivalent overcomes the adhesion when
the said bars resume their original position and are then raised free from the
yarn by the swing frame in the manner described in the herein before named
specification, the brush wo and the grooved opener a receding from the yarn
preparatory to the intermittent fall of the bars u and * by which the hanks
of yarn are stretched.
By these means the wet yarn is prevented adhering to the lower roller or
rollers when they are raised for the purpose of stretching the yarn, and the
yarn is opened and rendered even for subsequent treatment.
In the accompanying drawings the brush is shown placed outside and the
grooved opener within the hank of yarn, but we do not confine ourselves to this
precise position. We may if preferred reverse the positions or otherwise alter
the relative positions of the said brush and grooved opener without departing
from our invention; the mechanism herein before described may either be placed
at both ends of the machine as shown or at one end only.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is:-
1. In apparatus for stretching, opening and brushing hanks of yarn the com-
bination of a horizontally revolving roller placed over horizontal stretching
non-revolving rocking bars, said rocking bars having an intermittent rising and
falling motion, by which to stretch the banks of yarn placed over the aforesaid
revolving roller, substantially as herein before described.
2. In apparatus for stretching, opening and brushing hanks of yarn the com-
bination of a brush as at present employed for brushing hanks of yarn, and a
grooved roller placed in any relative position thereto, said roller rising and
falling, advancing and receding simultaneously with the brush in the manner
and for the purpose substantially as hereinbefore described.
3. In apparatus for stretching, opening and brushing hanks of yarn, the use
of a roller that is grooved spirally extending right and left from the centre
towards each end, or that is grooved from right to left or from left to right
the whole length of the roller, the said roller rising or falling in contact with,
and advancing and receding from the yarn, for the purpose and in the manner
substantially as hereinbefore described.
4. The improved mechanism for stretching opening and evening hanks of yarn
substantially as hereinbefore described and as illustrated on the accompanying
sheet of drawings.
