page_text: I, ELIJAH ASHWORTH, of the Moss Brook Works, Collyhurst, Manchester, in the
County of Lancaster, Machine Maker, do hereby declare the nature of this invention
to be as follows:-
My said invention relates to various improvements in or connected with spinning
and doubling frames and particularly to ring frames.
In such frames the spindles most generally in use are of the self-contained type
secured by nuts to the spindle rail. It is essential that the spindles should be truly
vertical but in practice it arises that with spindles of this type a truly vertical axis is
difficult to maintain.
I therefore dispense with these spindles and employ spindles similar or approxima-
ting to those of a spinning mule, although I do not claim as novel the use per se of a
mule spindle in conjunction with a ring and traveller.
In carrying my invention into effect I cast the spindle rail and lower rail through
which the "pokers" pass, in one and provide in the lower rail a footstep bearing for
the spindle and an upper bearing therefor in the usual spindle rail. One or both of
these rails is or are bored out sufficiently to permit of the passage of the wharve on
the spindle such wharve being disposed below the upper rail. The holes for the bearings
in the upper and lower rails are both bored out at the same time and as the rails are
cast together it will be evident that the centres of the holes accurately coincide, thus
providing for the absolute vertical position of the spindles. This truly vertical
position of the spindle is further maintained by the two bearing points of the spindle
being disposed so far apart in the upper and lower rails. The upper rail is provided
with a bush of brass or other anti-friction metal surrounding the spindle and the
lower rail is also provided with a footstep bearing of similar metal for the foot of the
spindle.
Automatic means are provided for the efficient lubrication of the spindle as follows.
The lower rail, which is the one preferably bored out sufficiently to permit of the passage
of the spindle wharve, is provided with a self-contained bearing recessed for the storage
of lubricant, occupying the holes and secured to the rail by pinching screws or other
means. The bearings may be bushed with brass or other anti-friction metal hollowed
out for the reception of the spindle foot. A supply of oil is carried in the bearing
and is conducted to the footstep of the spindle through a minute hole bored through
the brass, by the capillary attraction of a worsted or other thread or threads one end
of which is submerged in the oil, the other end being passed through the hole in the
central brass. Instead of the worsted or other threads I might bore out the central
brass with a suitably arranged passage or passages so that the revolution of the spindle
will induce a current of oil to the interior of the bush by one passage and expel the
same through the other or over the top of the bush. To exclude fluff and dirt from
the oil the bearing is preferably disposed in the rail slightly below the surface and a
metallic disc with a central hole for the passage of the spindle and which hole may be
less in diameter than the bearing brass, rests upon the bearing and level with the

page_text: surface of the rail. The supply of lubricant to the interior of the bearing is effected
through the central hole of the disc. If desired, to facilitate this, the self-contained
bearing may be bevelled down at one part of its circumference so that by pressing on
the edge of the cover at that point the cover may be tilted up and lubricant thus
introduced within the recessed bearing.
Or the cover may be formed slightly less in diameter than the interior diameter of
the bearing, and, resting upon the central bush or other part one edge of the cover
may be easily tilted within the bearing and lubricant introduced therein.
The cover may also be formed with turned down edges and the self-contained
bearing be reduced slightly in diameter at the top to receive the turned down edges
of the cover.
The upper bearing of the spindle may be a facsimile of the lower save that the
central brass would have to be bored through for the passage of the spindle. Or I
may simply form the upper bearing of a bush of brass bored out for the reception of
the spindle and jambed tightly into the hole bored in the upper rail. To lubricate
these bearings I might form a longitudinal groove or series of recesses in the upper
rail to contain a supply of lubricant and from this provide a number of grooves or
passages at right angles thereto leading to each spindle hearing.
The brass bush could be slightly raised from the surface of the rail and perforated
for the reception of a fine tube or the like occupying the groove leading to the oil
receptacle, so that a supply of oil is obtained.
The bearing bushes might however be level with the surface of the rail in which
case the rail might be perforated to conduct the tube to the interior of the bearing.
The grooves or recesses cut in the rail could be covered by metallic strips or covers
to exclude dust and fluff from the oil contained therein.
Although I have mentioned the spindle bearings and the method of lubricating
the same as being applied to a ring frame it must be understood that they may be
applied to the spindles of spinning mules.
Another part of my invention relates to the wharves of spindles used in textile
machinery. Such wharves are at present cast or formed from solid metal with a
central hole and are then forced upon the spindles.
Instead of this I propose to form the wharves from sheet metal by pressing, stamp-
ing or spinning the same until they acquire the requisite formation. This may be
effected so as to form the wharve of one or more parts secured together and with a
central sleeve of the requisite diameter and length to permit of the wharve being
firmly secured to the spindle.
By these means a considerable economy and lightness result in the construction
and weight of the spindles.
A further part of my improvements in the spindles relates to means for preventing
the paste or starch applied to the spindle when starting the winding of the cops, from
dropping into the bearings and thereby clogging same.
stanp, press or otherwise form a disc or cup from sheet metal or other suitable
material with a central sleeve which is forced upon the spindles below the point where
they are pasted. The liquid paste or starch falling on to the disc or cup is thrown off
by the centrifugal force of the revolving spindle and so prevented from trickling into
the bearing.
Where tubes are used upon which to start the cop the disc or cup would be useful
to act as a stop for the tube instead of the wire ring at present used.
Lastly my invention relates to the rings of ring spinning and doubling machinery
and particularly to the type of ring described in Specification of Letters Patent
No. 4386 of 1897 obtained by me in conjunction with James Buckley and John
Henry Buckley.
Such rings are formed with an outer flange of less thickness than the body of the
ring.
These flanges are forced into holes drilled in plates secured to the ring rail.
I now dispense with such flanges and thereby obtain an increased thickness of
metal for forcing the ring securely within the hole in the plate.

page_text: The construction of the ring is also greatly facilitated and the rings may be
economically cut of the desired thickness from weldless steel tubing.

I, ELIJAH ASHWORTH, of the Moss Brook Works, Collyhurst, Manchester, in the
County of Lancaster, Machine Maker, 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 said invention relates to various improvements in or connected with spinning
and doubling frames and particularly to ring frames.
The accompanying sheet of drawings clearly illustrates my invention.
Fig. 1 is an end view partly in section showing so much of a ring spinning frame
as is necessary to illustrate my invention.
Fig. 2 is a view at right angles to Fig. 1.
The remaining figs. are detail views.
In ring spinning frames the spindles most generally in use are of the self-contained
type secured by nuts to the spindle rail. It is essential that the spindles should be
truly vertical but in practice it arises that with spindles of this type a truly vertical
axis is difficult to maintain.
I therefore dispense with these spindles and employ spindles similar or approximating
to those of a spinning mule, although I do not claim as novel the use per se of a
mule spindle in conjunction with a ring and traveller.
In carrying my invention into effect I cast the spindle rail a and the lower rail b,
through which the "pokers" pass, in one, and provide in the lower rail 6 a footstep
bearing A for the spindle c and an upper bearing d therefor in the usual spindle rail.
One or both of these rails a b is or are bored out sufficiently to permit of the passage
of the wharve c on the spindle c such wharve being disposed below the upper rail a.
The rails a bare provided with snugs ff which carry the tubes g through which the
pokers h slide.
The combined rails a bare as stated cast in one end connected together at intervals by
means of webs i formed with ribs j through which the rails are bolted to the frame B
by means of bolts k. Lateral adjustment of the rails a b is provided for by the slots /
in the rib and the frame B is provided with slots m (see Fig. 2) within which the
bolts will slide to permit of vertical adjustment. The holes for the bearings in the
upper and lower rails are both bored out at the same time, the large hole being bored
first and then serving as a bearing to steady the drill in boring the other hole, and
as the rails are cast together it will be evident that the centres of the holes accurately
coincide, thus providing for the absolute vertical position of the spindles c. It will
be obvious that the same purpose will be served if the two rails are bolted or secured
together before the bearings for the spindles are drilled. This truly vertical position
of the spindle is further maintained by the two bearing points of the spindle being
disposed so far apart in the upper and lower rails a b. The upper rail a is provided
with a bush of brass d or other anti-friction metal surrounding the spindle and the
lower rail is also provided with a footstep bearing of similar metal for the foot of the
spindle.

page_text: Automatic means are provided for the efficient lubrication of the spindle as follows.
The lower rail, which is the one preferably bored out sufficiently to permit of the
passage of the spindle wharve e is provided with a self-contained bearing A recessed
for the storage of lubricant, occupying the holes and secured to the rail by pinching
screws n (shown in dotted lines) or other means. The bearings may be bushed with
brasso or other anti-friction metal hollowed out for the reception of the spindle foot.
A supply of oil is carried in the bearing and is conducted to the footstep of the
spindle through a minute hole bored through the brass o, by the capillary attraction
of a worsted or other thread or threads p one end of which is submerged in the oil,
the other end being passed through the hole in the central brass o.
A plan view of the bearings A is shown at Fig. 5.
To exclude fluff and dirt from the oil the bearing is preferably disposed level with
the rail as shown in the drawings and a metallic disc pl with a central hole for the
passage of the spindle and which hole is less in diameter than the bearing brass,
rests upon the bearing brass and level with or it might be a little below the surface
of the rail. The supply of lubricant to the interior of the bearing is effected by
tilting the cover p¹ within the bearing A so as to introduce the spout of the oil can,
or the cover p¹ may be of equal diameter to the self-contained bearing which is
bevelled down at one part q of its circumference (see Fig. 4) so that by pressing on
the edge of the cover p at that point the cover may be tilted up and lubricant thus
introduced within the recessed bearing A.
The upper bearing of the spindle may also if desired be a facsimile of the lower
bearing A as shown in Fig. 3 save that the central brass o would have to be bored
through for the passage of the spindle. Or I may simply form the upper bearing of
a bush of brass bored out for the reception of the spindle and jambed tightly into
the hole bored in the upper rail as shown in Fig. 1.
Another part of my invention relates to the wharves of spindles used in textile
machinery. Such wharves are at present cast or formed from solid metal with a
central hole and are then forced upon the spindles.
Instead of this I propose to form the wharves from sheet metal by pressing,
stamping or spinning the same until they acquire the requisite formation. This may
be effected so as to form the wharve of one or more parts secured together and with a
central sleeve of the requisite diameter and length to permit of the wharve being
firmly secured to the spindle.
In Fig. 6 the wharve e is shown in section pressed, stamped or spun from one piece
of sheet metal, with a central sleeve e¹.
In Fig. 7 the wharve also shown in section is formed in two halves, from sheet
metal as described each half being provided with a sleeve e³, by means of which the
separate halves are secured to the spindle.
By these means a considerably economy and lightness result in the construction
and weight of the spindles.
A further part of my improvements in the spindles relates to means for preventing
the paste or starch applied to the spindle when starting the winding of the cops, from
dropping into the bearings and thereby clogging same.
I stamp, press or otherwise form a disc from sheet metal or other suitable material
with a central sleeve which is forced upon the spindles below the point where they
are pasted as shown in Fig. 9. The liquid paste or starch falling on to the disc ris
thrown off by the centrifugal force of the revolving spindle c and so prevented from
trickling into the bearing.
Where tubes are used upon which to start the cop the disc r would be useful to
act as a stop for the tube instead of the wire ring at present used.
Lastly my invention relates to the rings of ring spinning and doubling machinery
and particularly to the type of ring described in Specification of Letters Patent
No. 4386 of 1897 obtained by me in conjunction with James Buckley and John Henry
Buckley.
Such rings are formed with an outer flange of less thickness than the body of the
ring

page_text: These flanges are forced into holes drilled in plates s secured to the ring rail.
I now dispense with such flanges and thereby obtain an increased thickness of
metal for forcing the ring & securely within the hole in the plate 8.
The construction of the ring is also greatly facilitated and the rings may be
economically cut of the desired thickness from weldless steel tubing.
Fig. 9 shows a plan view of the ring plate 8 and ring t, Fig. 10 being a cross section
of Fig. 9.
The ring when cut from tubing as described is rounded on its inner periphery as
shown in Fig. 10. A very slight taper is given to the outer periphery and it is then
forced into the plate 8.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is.
1) In spinning and doubling frames casting the spindle rail a and lower rail b in
one or securing them together and providing the same with bearings for spindles
similar to or approximating to mule spindles, and boring out the holes for the bearings
at the same time so that the centres of the holes accurately coincide and thus ensure
an absolutely vertical position of the spindles substantially as described and shown.
2) The improved self-contained bearing carrying a supply of lubricant which is
conducted to the spindle through a minute hole by means of a worsted or other
thread, the bearing being provided with a cap or cover to exclude fluff and dirt from
the oil contained therein substantially as described and shown.
3) Forming the wharves of spindles used in textile machinery from sheet metal in
one or more parts by pressing, stamping or spinning the same until they assume the
requisite formation substantially as described and illustrated.
4) The disc r secured to the spindle below the position of the cop bottom to catch
and throw off paste or starch so as to prevent same from trickling into the bearings of
the spindle substantially as described and shown.
5) The improved form or construction of ring substantially as described and
illustrated in Figs. 9 and 10 of the drawings.
