Machinists, Union Iron Works, West Gorton, in the County of Lancaster, do
hereby declare the nature of this invention to be as follows:-
This invention relates to the motion for altering the lift of the rail after
each traverse or lift to form the cops.
It is designed and arranged to reduce the movement in a much greater ratio
than heretofore without the necessity of enlarging the size of the wheels say
from about 64 to 1.
The movement is set in the free end of the oscillating copping lever which
may be of ordinary or suitable construction operated by a heart cam.
In the casting at the end of the copping lever are fitted two shafts or spindles
one fixed in the casing or frame and the other fitted into bearings to rotate
therein. On the end of the fixed shaft outside the casting is fitted loose to
rotate thereon the ratchet wheel by which the motion is actuated and a small
pinion to rotate therewith and towards the other end of the same shaft loose
thereon a large pinion and a second small one rotating together. On the loose
shaft is fitted fixed thereto on the end outside the casting a large pinion with
which the first small pinion on the other shaft gears and at the other end of
the loose shaft and fixed thereto a small pinion gearing with the large pinion
on the fixed shaft. Loose on the loose shaft and free to rotate independently
of it is another large pinion to the boss of which the lifting chain is attached
this pinion gears with the second small pinion on the fast shaft and is rotated
thereby at the desired speed to take up the lifting chain which is wound upon
the boss. By this arrangement I obtain the desired movement to shorten the
lifting chain and alter the lift or traverse without increasing the size of the
pinions. The pinions I at present prefer to employ are in the ratio of 4 to 1
but these may be altered more or less as may be required.

COMPLETE SPECIFICATION.
Improvements in Copping Motions for Spinning Frames.
I, JAMES HARRISON, Sub-Manager at the Works of Brooks and Doxey Limited,
Machinists, Union Iron Works, West Gorton, in the County of Lancaster, 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 spinning machine in which the varn is

page_text: wound upon a bobbin or pirn by the action of a traversing rail and in par-
ticular to the motion for altering the lift of this rail after each traverse or lift
to form the cop.
It is designed and arranged to reduce the movement in a much greater ratio
than heretofore without the necessity of enlarging the size of the wheels say
from about 64 to 1.
It will be fully described with reference to the accompanying drawings in
which the copping lever is shown with my improved motion applied thereto.
Fig. 1. Plan.
Fig. 2. Elevation.
Fig. 3. Plan showing a modified arrangement of lever carrying the actuating
pawl.
Fig. 4. Elevation of same.
The improved motion is set in the free end of the oscillating copping lever A
which is of any ordinary or suitable construction operated by a heart cam
engaging the bowl a.
At the free end of the copping lever A in the frame B formed by the cast-
ing are fitted two shafts or spindles C and D the spindle C being fixed so as
not to rotate and the spindle D being fitted into bearings d to rotate therein.
On the end of the fixed spindle C outside the casting B is loosely fitted to
rotate thereon a ratchet wheel E actuated by the pawl e and lever F. The
ratchet wheel E carries or has attached at one side a pinion G which rotates
with it. At the other end of the fixed spindle C I place loose thereon a large
pinion H and a small pinion attached or connected to rotate together.
On the loose spindle D is fitted and fixed thereto on the outer end a large
pinion K with which gears the small pinion G attached to the ratchet wheel E.
At the other end of the loose spindle D is fixed the small pinion L to rotate
therewith and gearing with the large loose pinion H on the fixed spindle C.
Loose on the loose spindle D and free to rotate independently of it is another
large pinion M the boss N of which forms a barrel to which the lifting chain
is attached.
The pinion M is in gear with the small pinion on the fixed spindle C and
is rotated by it at the desired speed to take up the lifting clain which is wound
up upon the barrel N.
By this arrangement I obtain the desired movement to shorten the lifting
chain and alter the lift or traverse without increasing the size of the pinions.
The pinions I at present prefer to employ are in the ratio of 4 to 1 but these
may be altered more or less as may be required.
The ratchet wheel E and pinions G and K may be changed as required to
vary the speed of the chain drum N. The shaft D in Fig. 1 and the ratchet
wheel E in Fig. 3 may be rotated by applying a handle or key to the extended
end d¹.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. In a spinning frame the combination with the copping lever A of the
take up or copping motion comprising the fixed and loose spindles C and D
and the wheels and pinions E, G, K, L, H, ½, M and chain barrel N substantially
as described.
2. A copping motion for spinning frames constructed and arranged in com-
bination substantially as described and shown.
