PROVISIONAL SPECIFICATION.
Improvements in Machinery for Stretching and Brushing Sized
Hanks or Skeins of Cotton, Linen, or other Fibrous Materials.
I WILLIAM FOTHERGILL of 42 Seymour Street, Radcliffe in the County of
Lancaster, Machinist do hereby declare the nature of my said invention to be as
follows:-
The object of this invention is to construct a single or double machine whereby the
sized hank or skein of cotton linen or other yarn may be subjected to a stretching and
shaking action alternately with a brushing of the inside and outside of the "hank
whilst being carried around a pair of stretching rollers.
In performing my invention I mount the stretching rollers at the extremities of a
pair of shafts extending beyond the sides of the framework, and to the upper shaft I
impart a constant revolving motion whilst the lower roller is free to revolve upon its
axis. The shaft of the lower roller is so mounted in guide grooves in the sides of the
framework that it is capable of being intermittently raised by means of a pair of
tappet cranks or cams at each revolution of the shaft and then allowed to suddenly
fall again whereby I obtain the required shaking and stretching of the hank.
My improvements further embrace the employment of a pair of brushes mounted
upon bars at the upper extremities of a pair of lovers the fulcra of which are capable
of sliding up and down in suitable vertical guide grooves or their equivalents, so that
one brush is closed against the inner face of the hank of yarn whilst the other brush
is similarly closed against the outside of the same hank. By now connecting the
lower extremities or longer arms of these levers to either a single or a double crank
carried the one upon the tappet shaft hereinbefore mentioned and the other upon a
similar shaft (geared to revolve at the same speed but in the contrary direction to the
tappet shaft), I am enabled to close the brushes upon both faces of the bank of yarn
and then to draw the brushes down (whilst in contact with the yarn travelling between
them) and thus I effectually brush the bank of yarn alternately with the shaking and
stretching of the same as hereinbefore described.

Improvements in Machinery for Stretching and Brushing Sized
Hanks or Skeins of Cotton, Linen, or other Fibrous Materials.
1 WILLIAM FOTHERGILL, of 42 Seymour Street, Radcliffe, in the County of
Lancaster, Machinist, do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :-
The object of this invention is to construct a single or double machine whereby the
sized lanks or skeins of cotton linen or other yarn may be subjected to a stretching
and shaking action alternately with a brushing of the inside and outside of the banks
whilst being carried around a pair of stretching rollers.
On the accompanying drawing Fig. 1. is a front view; Fig. 2. a side view and
Fig. 3. a side sectional view of my improved hank stretching and brushing machine.
Fig. 4 is a plan view of Fig. 1 shewn partly in section.

In performing my invention I mount the stretching rollers a and b at the extremities
of a pair of shafts a' and extending beyond the side c of the framework and to the
upper shaft a I impart a constant revolving motion from the driving shaft & through

page_text: the first intermediate shaft e and diagonal shaft fand by bevel gearing g and worm
wheel gearing f¹ as illustrated whilst the lower roller is free to revolve upon its axis
or shaft . The shaft 61 is mounted in a socket. at its inner extremity hinged in
position to the stud 2 and guided.up and down sideways (or at right angles to its axis
by means of the rod 63 hinged to the stud ). This rod is linked by means of a
link to a tappet lever having a friction bowl at its extremity. The tappet lever
and parts connected therewith so hinged in position are capable of being intermittently
raised by means of a tappet cam i upon the shaft (driven through the intermediato
shafts e and ) coming in contact every time it revolves with the friction bowl ¹ and
then allowed to drop suddenly by their own gravity. In this manner 1 impart to the
lower roller b the necessary falling action and so obtain the required shaking and
stretching of the banks.
My improvements further embrace the employment of a pair of brushes k and k¹
mounted upon the longitudinal bars 2 and 3 at the upper extremities of a pair of
levers and mounted on each side of the machine and the fulcra or connecting
links 12 of which levers are capable of moving upd down simultaneously by being
connected through an oscillating rod 13 to the st id so that one brush k is closed
against the inner face of the hanks of yarn m whilst the other brush is similarly
closed against the outside of the same hanks. This is effected by connecting the lower
extremities or longer arms of these levers and to a pair of cranks n carried the
one upon the tappet shaft herein before mentioned and the other upon the second
intermediate shaft which is geared to revolve at the same speed but in the contrary
direction to the tappet shaft it. I am thus enabled as the cranks revolve to close the
brushes upon both faces of the hanks as seen in Fig. 3. and then to draw the brushes
down (whilst in contact with the yarn travelling between them) and in this manner I
effectually brush the hanks of yarn alternately with imparting to them the shaking
. and stretching as hereinbefore described.
The weight of the levers and brush bars etc. is counterbalanced by a weight p affixed
upon the tappet shaft i¹.
To raise the lower roller whilst introducing and withdrawing the hanks m I employ
a bell crank lever the short arm of which is connected to the tappet lever / as
illustrated. I prevent the lower roller b falling too far by having the extremity of the
tappet lever affixed to a chain 7 suspended from the back of the machine.
It will be apparent that by having a top roller at each extremity of the shaft a¹ and
by employing an additional lower roller and extending the brush bars at the opposite
side of the machine that a double hank stretching and brushing machine can be
constructed.
Having thus 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 :-
1st. The joint combination and arrangement of parts constituting my improved
hank stretching and brushing machine substantially as hereinbefore described and
illustrated on the accompanying drawing.
2nd. In a hank stretching and brushing machine, the employment of a lower roller
mounted and operating substantiaily as and for the purpose hereinbefore described and
illustrated on the accompanying drawing.
3rd. In a hank stretching and brushing machine the employment of longitudinal
brushing bars mounted and ope ating substantially as and for the purpose hereinbefore
described and illustrated on the accompanying drawing.
