I THOMAS HAWORTH of 41 Buxton Street Accrington in the County of Lancaster
Manager, Moscow Machine Works, Church, county aforesaid, do hereby declare the
nature of this invention to be as follows:-
This invention consists of an improved construction of friction connected with the
sized beam of machines for purpose referred to and comprises a combination and
arrangement of parts whereby the "friction" is adapted either to fine yarns and to
comparatively light warp or to heavy warp.
'
Apparatus for purpose aforesaid according to this invention comprises two outer
and one central disc. Within each space between the outer and central discs is a
plate gear wheel the plate of each wheel being recessed on both its sides or faces
and each recess contains flannel packing. When the discs and wheels are in
position on their shaft the inner gear wheel gears with a gear driving wheel and
so a part of the "friction" is called into operation and is adapted to finer yarns
or narrower warps. When however it is desirable to increase the friction a second
driving wheel is brought into gear with its corresponding wheel between the discs
and the whole friction is then brought into operation. Convenient levers and parts
for putting the wheels in and out of gear are provided.

Improvements in Yarn Sizing Machines.
I, THOMAS HAWORTH, of 41 Buxton Street, Accrington, in the County of
Lancaster, Manager of Moscow Machine Works, Church, county aforesaid, 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 improvements in friction motions used in combination
with yarn sizing machines for applying the necessary friction or drag to the sized
beam, the object of the invention being to so construct the friction motion that it
is adapted for use when sizing fine yarn and comparatively light warp, or for heavy
warp and coarse yarn.
The invention consists of a duplicate arrangement of friction motions, one of which
is sufficiently strong to apply the necessary friction when sizing light yarns and
warps, and by simple mechanism the extra friction can be applied when sizing
heavier yarns or warps.
A lever and weight is employed by which the friction can
Such being the nature and object of my said invention, the following is a
be adjusted and regulated.

page_text: complete description of same, reference being had to the annexed drawings, in
which-
Fig. 1 is a plan view of the improved friction motion for yarn sizing machines.
Fig. 2 is a view partly in section of the back of the improved motion.
According to this invention I employ a short shaft 1 carried in bearings 2. 2 fixed
to the frame 3: On the shaft 1 is a pinion wheel 4 driven from the cone drum
or driving shaft of the machine, and in turn driving the wheel 5 keyed on the
shaft 1, said wheel 5 gearing with and driving the plate gear wheel 6 which is
loose on the shaft 7 but held between the discs 8-9 free to slide on keys on the
said shaft 7 on the end of which is the plate and key or pin 10 which engages
with the flange of the beam in the ordinary manner.
Loose on the shaft 1 is a
second gear wheel. 11 in the boss of which is a recess 12 in which is received a
fork, pin, or runner 13 in the lever 14, and on. each wheel 5-11 is a half
clutch 15-15.
.
The wheel 11 gears with a second plate gear wheel 16 also loose on the shaft 7
but held between. the discs 9-17, and between the discs 8-9--17 and the plate
gear wheels 6-16 is a washer of flannel, leather, or other similar substance 18,
which makes a frictional contact between the discs. 8-9-17 loosely keyed on the
shaft 7, and the plate gear wheels 6-16 loose on such shaft 7 which is loosely
clipped or enclosed by the fork 18" at the lower end of the lever 19 which is free
to rock on the stud 20 fixed in the frame. At the upper end of the lever 19 is
an inclined surface 21 against which rests the runner 22 on the weighted lever 23.
The action is as follows:-When sizing light yarns or warps, the lever 14 is moved
so that the wheel 11 is out of gear with the wheel 5 and is consequently loose on its
shaft 1, and the wheel 5 drives only the plate gear wheel 6: but when sizing heavy or
coarse yarns or warps, the lever 14 is moved so that the clutch 15-15 engages and
the. wheels 5-11 are both, for the time being, fast on the shaft 1, and these wheels
gear with and drive the two plate gear wheels 6-16, and consequently the amount of
friction is greatly increased. By moving the weight on the lever 23 the amount
of friction can be adjusted, as the runner presses more or less against the incline 21,
which causes the fork 18 to exert the requisite endwise movement and pressure of the
discs 8-9-17 and wheels 6-16; whereby the frictional contact is regulated.
By the improvements herein described it will be seen that the amount of friction can
be greatly increased or reduced at will, and that when either the single or duplicate
friction is employed it can be adjusted and regulated by the counterbalance lever and
weight. The motion is carried in a bracket 3 which is fixed to the frame of the
machine.
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 general construction, arrangement, and combination of parts constituting
the improved friction motion for yarn sizing machines, as and for the purpose herein
described and substantially as illustrated by the annexed drawings.
(2) The shaft 1, wheels 5-11 with intervening clutch, plate wheels 6-16,
discs 8-9-17 and shaft 7, all in combination as and for the purpose herein
described and substantially as illustrated by the annexed drawings.
