I SAMUEL TWEEDALE, of Globe Works, Accrington, in the County of Lancaster,
Manager, do hereby declare the nature of my said invention for "IMPROVEMENTS
IN THE MANUFACTURE AND CONSTRUCTION OF "RINGS EMPLOYED ON RING
SPINNING FRAMES to be as follows:-
"
"
The rings for purpose of spinning fibres on ring spinning frames as heretofore
were made wholly of steel in one piece or ring which after being turned to the
required form were heated and hardened-By reason of the heating and hardening
processes and of the considerable variation in the thickness of the parts of the
whole ring the latter by unequal contraction or otherwise were commonly warped
ог " untrue
to a degree rendering them unfit for use and worthless except as
'scrap" or waste metal,-I avoid the loss and waste by constructing the rings as
follows:-

"
The ring proper, or part on which the "traveller" works I construct of steel as
also a holding or securing rim thereon, this ring and its rim are then hardened.
The shoulder of the ring which rests upon the ring rail as also its rim which is
received in the hole in the ring rail I construct of cast iron and bore out the
shoulder truly for reception of the rim of the hardened steel ring.
On the outside of the rim of this lower and cast iron part is chased or formed a
screw thread whilst the hole in the ring rail has a corresponding "she" thread-
The hardened steel ring is placed with its rim over the truly circular hole in the
cast iron shoulder or base and forced therein so that if elliptical or out of shape
through the firing and hardening it assumes the truly circular or cylindrical
form necessary-The completed ring is then screwed into the tapped hole in the
ring rail and is thereby held in position, there being no horizontal boring and
tapping of the ring rail nor horizontal holding screw necessary for securing the
rings (in ring rail) made as heretofore.

I, SAMUEL TWEEDALE of Globe Works Accrington in the County of Lancaster
Manager do hereby declare the nature of my invention for "IMPROVEMENTS IN
THE MANUFACTURE AND CONSTRUCTION OF "RINGS " EMPLOYED ON RING SPINNING
FRAMES" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The rings for purpose of spinning fibres on ring spinning frames as heretofore
were made wholly of steel in one piece or ring, which after being turned to the
required form were heated and hardened.
By reason of the heating and hardening processes and of the considerable
variation in the thickness of the parts of the whole ring, the latter by unequal
contraction or otherwise were commonly warped or "untrue" to a degree rendering
them unfit for use, and worthless except as "scrap" or waste metal.
I avoid the loss and waste by constructing the rings as follows,
The ring proper or part on which the "traveller" works I construct of steel as
also a holding or securing rim thereon the ring and its rim are then hardened.
The shoulder of the ring which rests upon the ring rail, as also its rim which is
received in the hole in the ring rail I construct of cast iron, and bore out the
shoulder truly for reception of the rim of the hardened steel ring.
On the outside of the rim of this lower and cast iron part is chased or formed a
screw thread whilst the hole in the ring rail has a corresponding "she" thread.
The hardened steel ring is placed with its rim over the truly circular hole in the
cast iron shoulder or base, and forced therein, so that if elliptical or out of shape
through the firing and bardening, it assumes the truly circular or cylindrical form
necessary.
The completed ring is then screwed into the tapped hole in the ring rail and is
thereby held in position, there being no horizontal boring and tapping of the ring
rail, nor horizontal holding screw necessary for securing the rings (in ring rail)
made as heretofore.
Such being the nature and object of my said Invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this specification in which
Fig. 1 is a section of improved construction of ring and section of the ring rail.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 is like section of ring held in ring rail by "set screw
the ring rail.
"
instead of tapping
The several views on sheet 2 of the drawings illustrate the several parts
separately and in section.
The ring proper 1 or part on which the traveller works I construct of steel as
also its holding or securing rim 2 thereon, the ring 1 and its rim are then hardened.
The shoulder 3 of the ring 4 which rests upon the ring rail 5 as also its riu 6
which is received in the hole 7 in the ring rail 5 I construct of cast iron, and bore
out the shoulder 8 truly for reception of the rim 2 of the hardened steel ring 1.

On the outside of the rim of this lower and cast iron part is chased or formed a
screw thread 9 whilst the hole 10 in the ring rail has a corresponding "she"
thread.
The hardened steel ring 1 is placed with its rim 2 over the truly circular hole in
the cast iron shoulder or base 3 and forced or sprung therein so that if elliptical
or out of shape through firing and hardening it assumes the truly circular or
cylindrical form corresponding to the hole in the part 4.
The completed ring is then screwed into the tapped hole in the ring rail and is
thereby held in position, there being no horizontal boring and tapping of the ring
rail, nor horizontal holding screw necessary for securing the rings (in ring. rail)
when the latter and ring rail are bored and tapped as described.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is;
Rings composed of two parts steel and cast iron or other metal, the two parts
thereof being constructed and combined substantially as and for the purpose herein
described.
