We, THOMAS BROUGHTON, CHARLES BRIGO, and THOMAS HARGREAVES
BRIGG, all of Keighley, in the County of York, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MEANS OR APPARATUS
EMPLOYED IN PREPARING, SPINNING, AND DOUBLING WOOL AND OTHER FIBROUS
MATERIAL," to be as follows:-
The object of the Invention is to obtain a more perfect preparing,
spinning, or doubling. For this purpose in place of the ordinary cap or
fly to aid the feeding on to the bobbin in preparing, spinning, and
doubling apparatus, we pass the fibre through one or other number of a
series of holes with slits thereto in a ring or flange, and which holes are
mostly lined with pot.
The number of holes through which the fibre is passed in this ring or
flange in its passage to the bobbin will depend on the extent of tension

The ring or flange in which these holes or openings are produced is
formed on a short tube formed with a wharve, and it is caused to revolve
at the speed desired by band or otherwise in or upon a stationary tube
or socket, within which the bobbin rises and falls as desired. The lower
part of this short tube or wharve carrying the ring or flange of holes
revolves in or is supplied with oil from an oil cup or channel, whilst it
rests on a hardened ring or step.
When a portion of the short tube or wharve is formed to revolve in a
cup or channel, that portion is externally formed with a screw thread
which is cut in a direction such that would cause it to unscrew in its
rotation, that is to say, supposing this socket with its ring to be caused
to revolve from right to left, this external screw would then be what is
called a left hand screw. By this means air is in the revolution of this
wharve caused to pass down the oil to prevent such oil from rising up
the external surface. We also form a corresponding thread in the
portion of this tube or wharve next the socket or on the corresponding
portion of the socket or hollow stud, except that whilst the direction of
this thread as applied on the interior of the short tube or wharve would
be in the same direction as that on the outside thereof, when such
thread is applied on the exterior of the socket or hollow stud, on which
such tube or wharve revolves it would be in the opposite direction. The
object in this case is to prevent the oil rising between the socket or
wharve, and the tube or hollow stud on or in which it turns and be
thrown on the yarn.
The spindles are each fixed stationary to their rising and falling rail,
and the bobbin tubes rest on friction washers on pillars formed to raise
the bobbins, so that their lower parts may be raised by the lifter rail
about to the level of the top of the socket or hollow stud and the feed
ring or flange.
The bobbins and their tubes are connected together by pin as usual in
cap spinning. These rings or flanges and their wharves may be formed
of ebony or other hard wood as well as of metal. We also apply in the oil
.cup or channel a ring of felt or other suitable material to prevent the too
free rising of the oil.
