I, JOHN JOHNSON BROADBENT of Harris Court Mill, Bradford, in the County
of York, Spinner, do hereby declare the nature of my said invention for IMPROVE-
MENTS IN APPARATUS FOR SMOOTHING THE YARN IN SPINNING AND TWISTING
MACHINES, to be as follows:-
This invention relates to certain improvements in that class of spinning known
as "cap" spinning, and has for its object the manipulation of the fibre in such a
that a better class of yarn is produced from the same quality of fibre, the
yarn being smoother, more lustrous, and fuller than can be obtained either by cap
or fly alone.
manner,
I accomplish my object by mounting an additional plate above the ordinary
spindle rail. Through this plate I form apertures, and attach to the upper side of
the plate adjustable metallic washers, so arranged that each washer can be set
concentrically with each spindle.
The plate is also regulated by nuts to such a height, that the top of the washers
are slightly below the bottom edge of the caps.
I form the bottom of the caps
with a conical ring, the underside of which is flat, broader than hitherto. By the
regulation of the aforesaid plate to which the washers are fixed, the same is
adjusted to such a height that any required space can be left between the caps and
washers, in which the yarn is confined, and which causes any projecting fibres to
wrap or lay around the body of the yarn, thus producing a better class of yarn,
being smoother, more lustrous, and fuller than can be obtained either by cap or fly
alone.
When the machine is employed for cap twisting, the additional plate is mounted
in exactly the same manner as when the machine is engaged on spinning yarn.
Dated this 25th day of November 1884.

I, JOHN JOHNSON BROADBENT, of Harris Court Mill, Bradford in the County of
York Spinner, do hereby declare the nature of my invention for "IMPROVEMENTS
'IN APPARATUS FOR SMOOTHING THE YARN IN SPINNING AND TWISTING MACHINES,”
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 certain improvements in that class of spinning known
as "cap" spinning, and has for its object the manipulation of the fibre in such a
manner, that long wool yarns produced from the same quality of fibre and at an
increased speed from two to three times that at which flyers can be run; are equal
in every respect to fly spun yarns as regards smoothness and lustre.
In the accompanying drawings Fig. 1, represents an elevation of a spindle with
cap and additional plate arranged according to my invention and Fig. 2, is a section
through the cap and additional plate.
The ordinary lifter rail A, is mounted and actuated in the usual manner, and to
the spindle rail B, I secure a number of short pillars C, for supporting an additional
plate D, through which is formed apertures E, for the bobbin. On the opposite
side of the said plate concentrically with each spindle secure by the small
screws G, the adjustable metallic washers H, which are flat on the upper surface.
The additional plate D, is regulated by the nuts on the pillars C, to such a height,
that the top surface of the metallic washers are slightly below the bottom edge of
the caps J, which are formed with a conical ring J, the underside of which is flat
and broader than hitherto.
By the regulation of the aforesaid plate D, by the before mentioned nuts; the
plate is adjusted to such a height, that any required space can be left between the
caps and washers, which confines the yarn as it passes between the cap and washer
to the bobbin, thereby causing any projecting fibres, to lay around the body of the
yarn; thus producing a class of yarn as smooth and lustrous as fly spun at the
increased speed before named, consequently, manipulating more fibre in a given
time in proportion to the increase of speed.
When the machine is employed for cap twisting the additional plate D, is
mounted exactly in the same manner as when the machine is engaged on spinning
yarn,
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
The combination of a cap with an adjustable washer arranged substantially in
the manner and for the purpose as hereinbefore described.
