I JOHN ELCE, of 9 Hopwood Avenue, Manchester, in the County of Lancaster,
Machine Maker, do hereby declare the nature of said Invention for IMPROVE-
MENTS IN RING SPINNING FRAMES, PART OF WHICH IS APPLICABLE ALSO TO FLYER
FRAMES, to be as follows:-
My invention relates chiefly to ring spinning frames and it consists in a new
arrangement of the drawing rollers, and improvements in the ring and traveller.
With reference to the first part of my Invention, it is now customary to place
the axes of the front pair of drawing rollers at such an angle to the yarn as it
passes from them to the thread guide that the twist can run up to the nip of the
rollers; the second and back pair of rollers have been placed in the same line with
the yarn from the thread guide to the front rollers; in this arrangement a self
weighting top back roller is ineffective as its weight rests too much on its front
bearing in place of on the lower roller and the roving.
To remedy this defect I propose to lower the back rollers until the upper surface
of the lower roller stands at about the same level as the top of the lower roller of
the second pair so that the roving passes in a horizontal line or nearly so from the
back pair to the second rollers, and from the nip of the second pair the roving
passes in a direct line through the front drawing rollers through the thread guide
to the spindle.
The same result may be attained when the roving passes in a straight line from
the back rollers to the front pair by moving back the self weighted back roller
until it stands perpendicularly or nearly so over the centre of its lower roller and
so bears with its weight upon the roving.
The front and second pair of rollers are weighted in the usual or other convenient
manner.
This arrangement of drawing rollers is equally applicable to flyer tbrostle
Spinning frames

page_text: In the second part of my Invention for the improved ring and traveller I prefer
to employ a ring with a groove to support a separate ring with three small feet or
projections which rest in the groove; to this extra ring are hinged or pivoted one or
more arms preferably two which curve inward toward the centre of the ring; these
arms may be provided with presser feet beyond their hinge, the weight of which
acting by centrifugal force keeps the arms out toward the spindle.
The yarn from the thread guide is passed round either of the arms and then
through an open eye at its end on to the bare spindle or tube where it is wound
without being subjected to the great strain necessary when an ordinary ring and
traveller are employed.

Applicable also to Flyer Frames.
I JOHN ELCE, of 9 Hopwood Avenue, Manchester, in the County of Lancaster,
Machine Maker do hereby declare the nature of said invention for IMPROVEMENTS
IN RING SPINNING FRAMES PART OF WHICH IS APPLICABLE ALSO TO FLYER
FRAMES, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention relates chiefly to ring spinning frames and it consists in a new
arrangement of the drawing rollers.
It is now customary to place the axes of the front pair of drawing rollers at such
an angle to the yarn as it passes from them to the thread guide that the twist can
run up to the nip of the rollers; the second and back pair of rollers have been
placed in the same line with the yarn from the thread guide to the front rollers.
In this arrangement a self weighting top back roller is ineffective as its weight
rests too much on its front bearing in place of on the lower roller and the roving.
To remedy this defect I propose to lower the back rollers until the upper
surface of the lower roller stands at about the same level as the top of the lower
roller of the second pair so that the roving passes in a horizontal line or nearly so
from the back to the second pair of rollers, from the nip of the second pair of
rollers the roving passes or may pass in a direct line through the front drawing
rollers to the thread guide.
The front and second pair of rollers or either pair are weighted in the usual or
other convenient manner but the top back roller is selt weighting as it is placed
perpendicularly or nearly so over the lower back roller and therefore bears with
all its weight upon the roving.
This arrangement of drawing rollers is equally applicable to flyer throstle
spinning frames.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings reference being
had to the figures and letters marked thereon.
In Figure 1. a is the beam of a spinning frame, b the roller stand and c the cap
bar; the axes of the two front pairs of drawing rollers d d' and e el respectively
may be placed at right angles to the path of the roving from the rollers to the
thread guide g, the upper surface of the lower back roller fis placed at about the
same level as the top of the lower roller e of the second pair and the back top
roller has its axis either directly over the lower roller or preferably as shown set
a trifle in advance of it so that it bears with its full weight on the roving.
In this arrangement the front top roller d only is shown covered and weighted
but if preferred the second top roller e may also be covered and weighted by any
convenient form of weighting apparatus.
Fig. 2 represents a slightly modified arrangement of drawing rollers.
In this case the axes of the two front pairs of rollers are not set at right angles
to the path of the roving and both the top rollers d¹ and are covered and

page_text: weighted. The back top roller f¹ is supported in guides over the lower roller f so
that its full weight bears upon the roving as in the previous arrangement.
By my Invention I am enabled to set or alter and adjust the position of the two
front pairs of drawing rollers to suit the class of yarn to be spun and this setting
or adjustment is effected independently of the back rollers the position of which
remains, or may remain unchanged the roving in all cases passes horizontally or
nearly so from the back to the second pair of rollers.
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―
In a spinning frame, the combination with two pairs of front drawing rollers, of
a self weighting top back roller, the rollers being so arranged that the roving
passes horizontally or nearly so from the back rollers to the second pair of rollers,
substantially as herein set forth for the purposes specified.
