PROVISIONAL SPECIFICATION.
Improvements in the Lifting-pokers and Ring-rails of Spinning and
Doubling Machines.
EDMUND TWEEDALE SAMUEL TWEEDALE and JOSEPH SMALLEY Machine
Makers Castleton, near Manchester, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the lifting-pokers & ring-rails of
spinning & doubling machines such as are described in Letters Patent No. 5450,
1890 granted to Samuel Tweedale and has for its purpose the providing of greater
bearing surface & dispensing with the central pivot on poker top and the hole
through ring rail for its reception.
In carrying out this our invention we use a double flanged ring rail into which
are formed circular shaped recesses for the shoulders of the poker to fit into.
The shoulders on the top of the poker are made to fit into these recesses.
We prefer to make them cone shaped so as to give facility for fitting them
to each other, as it is important that there should be no looseness or play when
working.
Cutting away the top surface of the shoulders on the poker top allows the taper,
or conical part, to enter further into the recess in the ring rail and thus takes away
all looseness and tendency to get out of proper working position.
To prevent the poker turning round in the recess we put a small pin or screw
in the ring rail and form a hole in the shoulder of the poker to receive it.
Dated this 25th day of May 1892.

COMPLETE SPECIFICATION.
Improvements in the Lifting-pokers and Ring-rails of Spinning and
Doubling Machines.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY,
Machine Makers, Castleton, near Manchester, 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 the lifting pokers and ring rails of
spinning and doubling machines such as are described in Letters Patent No. 545000
granted to Samuel Tweedale and the present invention has for its object the
providing of greater bearing surface and dispensing with the central pivot on
poker top and the hole through ring rail for its reception as described in Speci-
fication of said Patent.
In carrying out this our invention we use a double flanged ring rail, into which
are formed circular shaped recesses for the shoulders of the poker to fit into.
The shoulders on the top of the pokers are made to fit these recesses.
We prefer to make them cone shaped so as to give facility for fitting them to
each other as it is important that there should be no looseness or play when
working.
In order that our invention may be more fully understood, we will now make
reference to the accompanying sheet of drawings illustrative thereof, wherein
Fig. 1 is front elevation of our improved lifting rail and poker, Fig. 2 is plan
view, and Fig. 3 cross section of same.

page_text: Fig. 4 is a view looking on the top of the poker.
Fig. 5 is a view of the underside of the ring rail shewing the poker in
position.
A represents the ring rail having a flarge B on both sides and these flanges have
a semicircular recess Cinto which the shoulder D on the top of the pokers E are
made to fit; the curved recess in the flanges and the shoulders of the poker being
made of corresponding shape and size as indicated in the drawings. To prevent
the poker turning around in the recess, we employ a small pin or screw which
enters a hole or recess G formed in the shoulder of the poker the use of which,
will obviously prevent the poker from turning around. We wish it to be under-
stood that the shoulders D on the top of the poker are slightly conical, as also is
the recess C in the flanges as shewn in Figs. 1, 3, and 6, such conical parts freely
allowing the ring rail to be lifted out of a true horizontal line as shewn in Fig. 6
without breakage.
The conical parts also permit the ring rail to freely get back or assumė its
horizontal position again.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
In ring rails of spinning and doubling machines, the conical recesses in the
flanges of the ring rail and the cone shaped shoulders of lifting pokers employed
in the manner and for the purpose shewn and described herein.
Dated this 23rd day of February 1893.
