PROVISIONAL SPECIFICATION.
An Improvement in the Cop Building Apparatus of Mules and
Spinning Frames.
I JOHN MUIR HETHERINGTON of the Firm of John Hetherington and Sons
Limited, of the Vulcan Works, Pollard Street, Manchester, in the County of
Lancaster, Machinists, do hereby declare the nature of this invention to be as
follows:-
My invention relates to parts of the apparatus which regulate the building of
the cops in mules and spinning frames. In such apparatus a ratchet wheel is
turned intermittently and gives motion to parts which control the rate at which
the cops are built up or increased in length during the winding upon the spindles.
In the cases of mules the said ratchet wheel has been fixed upon a building screw
which controls the action of parts which lower the copping rail such rail being
lowered to a greater extent at each draw for coarse counts of yarn than for finer
counts as is well understood. To adapt the mule to spin a required count it has
been necessary to provide a screw of a suitable pitch having a ratchet wheel
formed with a suitable number of teeth and when the mule bas been required for the
spinning of other counts it has been necessary to change the screw or the ratchet
wheel or both.
To enable the adaptation to be more readily effected I actuate the screw by
means of a ratchet wheel which is mounted to revolve on an axis which is separated
from that of the screw and I connect the wheel with the screw by means of change
wheels. The same ratchet wheel and screw can be used in the spinning of a wide
range of counts it being only necessary to apply connecting gearing of proportions
suitable to the count required and as the ratchet wheel remains the same the action
of the parts which actuate such wheel is not interfered with. The ratchet wheel
may be changed when advisable. In the cases of spinning frames change gearing is
similarly employed to connect the ratchet wheel with the worm shaft or part which
controls the action of the building apparatus.

COMPLETE SPECIFICATION.
An Improvement in the Cop Building Apparatus of Mules and
Spinning Frames.
I JOHN MUIR HETHERINGTON of the Firm of John Hetherington and Sons
Limited, of the Vulcan Works, Pollard Street, Manchester, in the County of
Lancaster, Machinists, 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 and accompanying drawings:-
My invention relates to parts of the apparatus which regulate the building
of the cops in mules and spinning frames. In such apparatus a ratchet wheel
is turned intermittently and gives motion to parts which control the rate at
which the cops are built up or increased in length during the winding upon the
spindles.
In the cases of mules the said ratchet wheel has been fixed upon a building
screw which controls the action of parts which lower the copping rail such rail
being lowered to a greater extent at each draw for coarse counts of yarn than

count it has been necessary to provide a screw of a suitable pitch having a ratchet
wheel formed with a suitable number of teeth and when the mule has been required
for the spinning of other counts it has been necessary to change the screw or the
ratchet wheel or both.
To enable the adaptation to be more readily effected I actuate the screw by means
of a ratchet wheel which is mounted to revolve on an axis which is separated
from that of the screw and I connect the wheel with the screw by means of change
wheels.
My invention is illustrated by the accompanying drawings of which
Fig. 1 represents a side view and Fig. 2 an end view of one end of the building
screw of a mule the figs. also showing the parts which I employ to give motion to
the screw.
In the said figs. a is the building screw which is of an ordinary or suitable length
although only one end of the screw appears in the drawings. Upon the screw end
is fixed a spur wheel in place of the ordinary ratchet wheel and this spur wheel
is in gear with a second wheel or pinion c which is mounted to revolve upon a
stud d and is attached to a ratchet wheel e. The said stud is fixed in a bracket f
which is adjustably bolted or secured to the framing of the mule so that the
distance between the centres of the screw and stud may be varied to suit the sizes
of the spur wheels employed. A lever g is also mounted upon the said stud and
carries a pawl which engages with the teeth of the ratchet wheel. The lever g
in the example is intended to be operated by means of a chain i in the ordinary
manner but the method of actuating the lever may be varied to suit differing
descriptions of mules. When the lever is drawn upward by the chain the
ratchet wheel is partly revolved whereby the screw is turned through the gearing.
The spur wheels can be readily exchanged for others of different proportions.
The same ratchet wheel and screw can be used in the spinning of a wide range of
counts it being only necessary to apply connecting gearing of proportions suitable
to the count required and as the ratchet wheel remains the same the action of the
parts which actuate such wheel is not interfered with. The ratchet wheel may be
changed when advisable. In the cases of spinning frames change gearing is
similarly employed to connect the ratchet wheel with the worm shaft or part which
controls the action of the building apparatus.
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. In spinning machinery a ratchet wheel connected by means of changeable
spur gearing with the screw shaft or worm shaft which controls the action of the
building apparatus.
2. In spinning mules the ratchet wheel mounted upon a stud or shaft separate
from the building screw and connected with such screw by means of changeable
spur gearing substantially as set forth and indicated.
