Improvements in the Construction of Machinery or Apparatus
Stretching, Brushing, and Opening 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 that class of apparatus known as hank stretching and
brushing machines, such for example as those described and claimed in the Speci-
fication of Letters Patent No. 453489 granted to William Fothergill in
which the hanks of yarn (as they are taken from the sizing or dyeing machine in
a wet state) are opened stretched and brushed by means of brushes acting on the hanks
of yarn which are placed on stretching rollers at each side of the machine, thus
freeing the yarn from any superfluous size or other extraneous matter, stretching
and opening out the same, and preventing entanglement in its subsequent treat-
ment.
Our improvements on this class of machinery or apparatus and the manner in
which the same is to be performed or carried into practical effect will be readily
understood on reference to the two sheets of drawings hereunto annexed and the
following explanation thereof.
Fig. 1 on the drawings is a front elevation,
Fig. 2 a plan view, and Fig. 3 a vertical section of a yarn stretching and
brushing machine constructed according to our improvements. Fig. 4 is a
sectional plan view showing the swing-frame for supporting the lower stretching
rollers.
a is the framing of the machine, the main driving shaft which actuates the
second motion shaft c by means of a pinion d and spur wheel e. Upon the shaft
is keyed a bevil wheel 'f which by means of a similar wheel 9 gives motion to a
carrier shaft h on the other end of which is keyed a worm i driving a worm
wheel k fixed on the shaft / which forms the axle of the two top rollers m m,
and is carried in fixed bearings mounted on the frame a.
These top rollers m are therefore stationary as regards their position but have
a slow revolving motion imparted thereto.
The lower rollers m m (which act as stretching and shaking rollers) are
mounted so as to revolve loosely on an anxle bar n* forming part of a swing-
frame (see Fig. 4) carried by an oscillating shaft o.
To the latter is keyed, or adjustably attached a curved arm p the upper end of
which is provided with a friction roller or bowl q actuated by a tappet or cam r

page_text: fixed on the second motion shaft c; and thus once during every revolution of the
said shaft the swing-frame n.and its rollers m m will be raised up and allowed
to fall again, so as to give an intermittent shaking and stretching motion to the
hanks of yarn, the rollers m being always kept parallel to the rollers m.
A hand levert (Fig. 3) is also attached to the machine whereby the swing
frame and rollers m may be raised up for the purpose of placing-on and
doffing" the hanks.
The brushing and opening of the yarn is effected by means of two brushes u
and one acting on the outside, and the other on the inside of the hank, the
said brushes being connected together across the machine and having a rising
and falling and at the same time an advancing & receding motion given to
them by means of two crank pins on two face plates one of which keyed
is at each end of the second motion shaft c.
Each crank pin has a connecting rod a hinged to it, a pin y at the lower end
of which moves up and down in a vertical slot made in the frame (see Fig. 3).
This pin y is connected by a diagonal stay arm or link z to the frame on which the
brushes and * are fixed back to face as shown. As the face plate w revolves it
gives the required compound and parallel motion to the brushes.
The brush frame is attached to the connected rod by the pin and its
weight is counterbalanced by the weights s on the shaft e (Fig. 2) which also
withdraw the brushes from the hanks as soon as the strap is put onto the loose
pulley. The fingers on the end of the arms which are pivoted to the frame a
prevent the hanks from working off the ends of the rollers, but can be turned
aside for doffing and replacing the hanks.
is the strap fork lever for throwing the strap on or off the driving pulley.
It will be evident that a single machine can be made on the same principle by
omitting the second set of rollers & brushes, where space is an object, but of
course the double machine is more economical, and only requires one third more
space.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we would remark in
conclusion that we do not seek to claim all means for keeping the rollers m
parallel with the rollers m, nor do we claim any means for brushing the yarn on
both inside and outside the hank whereby the brushes are not carried back to
face, such means for brushing being described in the Specification of Fothergill's
Letters Patent aforesaid, but we declare that what we claim is:-
First: The improved construction of machinery or apparatus for stretching
brushing and opening hanks of yarn substantially as hereinbefore described and
illustrated by the drawings annexed.
Secondly: We claim the method of and apparatus for actuating the brushes
back to face substantially as above described, and
:
Thirdly The apparatus for maintaining the movable rollers always parallel
to the fixed rollers and imparting to the former an intermittent rising and falling
motion inside the hanks, substantially as described, and illustrated by the annexed
drawings.
