PROVISIONAL SPECIFICATION.
Improvements in Self-Acting Mules, Flyer and Ring Spinning Frames.
We, ROBERT CLEGG, of Count Hill, Oldham, in the County of Lancaster, Engineer,
and JAMES CLEGG, of Spring Field House, Stoneleigh, Oldham aforesaid, Engineer,
do hereby declare the nature of this Invention to be as follows:-
Our invention relates to improvements in self-acting mules, flyer and ring spinning
frames and our improvements consist of a novel arrangement for weighting the
drawing rollers.
Prior to our Invention it has been customary to weight, the front top line of
drawing rollers by means of weight hooks engaging the rollers at or about mid length
where they are recessed and reduced in diameter to receive such weight hooks. The
chief drawbacks to this arrangement are that the operation of recessing the rollers is
expensive and the continuity of the drawing surface is broken by such recesses.
According to our improvements we dispense with the recesses and make the
drawing surface of each roller continuous and of one uniform diameter and we apply
the weight directly to the roller pivots of two adjoining rollers preferably by hinging
the cap nebs to the ordinary cap bar and allowing the weight hooks to engage and
depend from such hinged cap nebs.

COMPLETE SPECIFICATION.
Improvements in Self-Acting Mules, Flyer and Ring Spinning Frames.
We, ROBERT CLEGG, of Count Hill, Oldham, in the County of Lancaster, Engineer,
and JAMES CLEGG, of Spring Field House, Stoneleigh, Oldham aforesaid, Engineer, 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:-
Our invention relates to improvements in self-acting mules, flyer and ring spinning
frames and our improvements consist of a novel arrangement for weighting the
drawing rollers.
Prior to our Invention it has been customary to weight the front top line of drawing
rollers by means of weight hooks and saddles engaging the top rollers at or about mid-
length where they are recessed and reduced in diameter to receive such hooks and
saddles. The drawbacks to this arrangement are, the continuity of the leather surface
of the drawing roller is broken and the traverse of the ends of roving on the same is not

page_text: sufficient, the rollers are also weakened by the recess and when weighted they spring
and the outer ends of the bosses have nott.bhe same pressure on the bottom rollers as
the inner ends of the bosses have.
The principal object of our Inventioniis.to avoid recessing the front top drawing
rollers and to obtain a continuousand unbroken drawing surface between the pivota
of each of such rollers, also to get more traverse of the ends of roving and avoid any
deflection of the rollers when weighted.
According to our improvements we dispense with the recesses and make the
drawing surface of each roller continuous and of oue uniform diameter and we apply
the weight directly to the roller pivots of two adjoining rollers preferably by hinging
the cap nebs to the ordinary cap bar and allowing the weight hooks to engage and
depend from such hinged cap nebs.
In the accompanying three Sheets of drawings-
Figure 1 is an end elevation and Fig. 2 a front elevation, both partly in section,
and Fig. 3 a plan of the drawing rollers to which our improvements are applied.
Fig. 4 is a detail view of the pivoted cap neb.
Fig. 5 is an end sectional elevation of an alternative arrangement in which the
weight hooks are applied directly to the pivots of the front top drawing rollers.
In these views, a designates the roller stand and 6 the ordinary cap bar attached
to the stand a in the usual way. To the cap bar.b, in the arrangement Figs. 1 and 3,
we secure a bracket c which is preferably adjustable, and to this bracket we pivot the
cap neb or saddle neb d instead of fixing the same rigidly. as hitherto customary.
In Fig. 1 are seen the three pairs of drawing rollers marked e e¹, ff and gg¹
respectively of which each of the front top rollers e is made, according to our
Invention, with a continuous and unbroken leather covered drawing surface as clearly
shown in Figs. 2 and 3. Each pivoted cap or saddle neb d rests upon the adjoining
pivots of a pair of front top rollers e, and to prevent contact of the pivots and too
inuch endwise movement of the said rollers the cap neb d is preferably divided on its
under side by a web or mid-feather d¹ which lies between and separates the pivots as
shown in Fig. 2.
The saddle weight hooks h h may be of two kinds and may be used in combination
as shown, those marked à resting upon the top of the cap nebs d which are recessed
to receive them as clearly shown in Fig. 4, while those marked ' are hooked into
holes made in the cap nebs d to receive them at a point sufficiently behind to allow
them to hang clear of the front bottom rollers e. The usual wires i carrying
weights are hooked on to the lower ends of the hooks h' to weight the front top
rollers e.
In some cases, as for example, when a stripping roller or dirt shaft is employed to
clean the front bottom rollers e the weight hooks A which rest on the top of the cap
nebs d can be employed throughout the machine and the weight hooks A be dispensed
with. In other cases, as for example, when a wood under clearer is employed, the weight
hooks he can be employed opposite each roller stand a, and the other weight hooks h¹
behind the front bottom rollers e' at the intermediate points. In some cases it may
be desirable to use the weight hooks alone.
In the arrangement illustrated by Fig. 5 we dispense with the pivoted enp neb d
and apply a weight hook A directly to the adjoining pivots of the front top rollers e
or we may apply a separate weight hook A to each pivot of each front top roller e.
Having now particularly described and ascertained the nature of our said 'Inven-
tion and in what manner the same is to be performed we declare, that what we
claim is :-
1. Weighting the front top drawing rollers of a self acting mule or flyer or ring
spinning machine by means of weight hooks or equivalent appliances depending
from the cap nebs which are pivoted for the purpose and whereby the necessity for
recessing the said front top rollers is avoided and a continuous unbroken drawing
surface between the pivots of each roller is obtained substantially as herein set forth.
2. Weighting the front top drawing rollers of self-acting mules, flyer and ring

page_text: spinning frames by weight hooks or equivalent appliances acting directly on the
pivots or journals of the said front top rollers and in the space usually occupied by
the cap bar or neb substantially as and for the purposes herein set forth.
3. In combination, the cap bar b, the pivoted cap neb d and the weight hook or
hooks depending therefrom, all substantially as herein set forth.
4. The combination with the pivots of an adjoining pair of front top rollers e said
rollers having continuous unbroken drawing surfaces, of the pivoted cap neb d
preferably having a mid-feather d' and weights depending from such cap neb
substantially as herein set forth.
5. The combination with the pivots of the front top rollers e, said rollers having
continuous unbroken drawing surfaces, of the weight hooks h applied directly to the
pivots of said rollers and in the space usually occupied by the cap bar or neb
substantially as herein described with reference to Fig. 5.
