Schofield Whitworth at the Office of the Commissioners of Patents,
with their Petition, on the 23rd May 1873.
We, JAMES HIGGINS, of Salford, in the County of Lancaster, Machine
Maker, and THOMAS SCHOFIELD WHITWORTH, of the same place,
Manager, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR SPINNING AND DOUBLING COTTON AND OTHER
FIBROUS MATERIALS," to be as follows:-
:-
Our Invention relates,―
Firstly. To an arrangement of spindle apparatus applicable especially
to the ring and traveller system, but which may also be adapted for
use when flyers are employed, and consists in using a suspended tube as
the revolving spindle, and in certain means of applying lubricating
material. For these purposes we employ a stationary spindle around
which (but by preference having a slight space) is a tube having at its
upper end a part fitting loosely into the spindle, the lower part of the

page_text: tube having a bearing by a bush or by similar means.
For the purposo
of lubrication we place a receptacle for oil or other such material around
the lower part of the tube, and the wharve we form with an annular
recess in which the said receptacle is situate. In place of this
arrangement the revolving tube may rest upon the bottom of the
lubricating chamber or upon a shoulder on the fixed spindle, and be
bushed at its upper end to keep it in a central position. By increasing
the length of the aforesaid tube a flyer may be adapted thereto.
Secondly. One Invention refers to constructing certain parts of ring
and traveller frames and mules, whereby we secure greater accuracy in
the relative positions thereof. As these machines are now constructed
the spindle rails are formed in two parts, which are separately drilled for
the reception of the spindles and the lifting rods, and it has been found
that when subsequently fitted together they do not always assume a
position by which the rings are truly concentric with the spindles. To
avoid this we cast the two rails together in one piece, and drill them
through for the reception of the spindles and the lifting rods, and the
desired concentricity is thus obtained; or instead of casting the parts
together we unite them by bolts or similar means, previously to
drilling them. This union of the parts may be for the whole length
of the frame or in sections, but in either case the effect will be that if
any one part be deranged in position, the other will follow bodily.
The next part of our Invention relates to doubling frames, and refers
to a method of arresting the drawing off from the creel when an end
breaks, for which purpose we cause the said breakage to hold the thread
behind the rollers, so that they will slip over it instead of drawing it
forward.
The arrangement we propose is as follows:-Upon a fixed centre is
an arm which carries a blade supported by the thread at the front of the
rollers, the other end of the said arm having a projecting part capable of
building the thread against a fixed part, or in a recess at the back of the
rollers.
When an end breaks the above mentioned blade falls, and by causing
the arm which carries it to turn upon its centre binds the thread so as to
hold it against the friction of the rollers. The above mentioned blade
may act in concert with a stationary blade which supports the thread,

page_text: and we propose also to decrease the power of drawing forward the thread
by causing the turning down of the arm to lock the top roller, and so
prevent it from revolving, a method of effecting which is to apply a
projecting part to the said arm, which part falls into a ratchet wheel or
similar notched surface on the axis of the roller.
