THOMAS WHITFIELD WHEELWRIGHT, Spinners and Manufacturers all three of
Bradford in the County of York. "IMPROVEMENTS IN APPARATUS EMPLOYED IN
SPINNING. DOUBLING AND TWISTING FIBROUS SUBSTANCES "
This invention relates to that class of spinning, doubling, and twisting machinery
known as "Cap frames," and the improvements consist in constructing caps with
bottom projecting surfaces and flanges; over the bottom projecting surface of each
cap and on the top of the flange is placed a wire ring; the ring is kept in working
position by the bottom end of a metal tube which is passed over the cap the
bottom end of the tube rests on or comes into contact with the top of the projecting
surface, the tube is made nearly half the length of the cap and adds weight to the
cap producing a more steady and more regular spinning or twisting; it is obvious
that the metal tube varies in length and thickness according to requirements. The
caps may be made of cast iron or cast steel or of steel tubing having flanges welded
to the caps, or the caps may be made of cast iron and steel or of any other suitable
material. The wire rings are made with hooks, eyes, or twirls and the strength
or thickness of the wire forming the wire rings varies according to the different
counts of the yarn to be produced and to give more or less drag.

In spinning, doubling and Twisting, the yarn passes from the cap to the hook,
eye or twirl of the wire ring and from there over the edge of the flange of the cap
to the bobbin or spool giving an uniform drag to the yarn winding on the bobbin
or spool, wrapping in the loose projecting fibres of the yarn, giving more regular
spinning and twisting and at a greater speed.

"
The said invention relates to that class of spinning, doubling and twisting
machinery known as "Cap frames" and the improvements consist in constructing
caps with bottom,projecting surfaces and flanges; over the bottom projecting surface
of each cap and on the top of the flange is placed a wire ring or traveller and the
ring or traveller is kept in working position by the bottom end of a metal tube
which is passed over the cap; the bottom end of the 'tube rests on or nearly comes
in contact with the top of the projecting surface; the tube is made nearly half the
length of the cap and adds weight to the cap producing a more steady and more
regular spinning or twisting; it is obvious that the metal tube varies in length and
thickness according to requirements.
The caps may be made of cast iron or cast steel or of steel tubing or any other
suitable metal and with flanges welded to the caps or the caps may be made of cast
iron and steel or of any other suitable material. The wire rings or the travellers
are made with hooks,, eyes or twirls and the strength or thickness of the wire
forming the wire rings or travellers varies according to the different counts of the
yarn to be produced and to give more or less drag.
In spinning, doubling and twisting, the yarn passes from the cap to the hook,,
eye or twirl of the wire ring or traveller and from there over the edge of the
flange of the cap to the bobbin or spool, giving an uniform drag to the yarn winding-
on the bobbin or spool wrapping in the loose projecting fibres of the yarn, giving
more regular spinning and twisting and at a greater speed.
:
In order to enable our improvements to be fully understood we will proceed to
describe the same by reference to the accompanying drawing in which figure 1,
represents a sectional elevation of a cap for spinning, doubling and twisting
machinery constructed according to our invention and figure: 2, is a front elevation
of the same; figure 3, is an enlarged view of the bottom part of the cap and the
metal tube shewing the position of the traveller when in operation; figure 4,
represents a plan of a traveller having a hook, eye or twirl for small counts in
spinning and twisting; figure 5 shews a traveller having a larger hook, eye or.
twirl for thicker counts; figure 6, represents a plan of a traveller having a
long hook, eye or twirl and figure 7, is a side view of the same; figure 8, is
a plan of a traveller having a small hook, eye or twirl and figure 9, is a side
view of the same; figure 10, is a plan of another form of traveller and figure 11
is a side view of the same. Similar letters of reference are used to represent
similar parts.
A, is, an ordinary fixed spindle carrying at its upper end a cap. B, made
according to our improvements; the cap B, is made with straight sides C, for
a certain portion of its length, on which straight part C, slides .a tube D, which
is fixed in position by a spring N. The bottom end of the cap B, is made.
with a projecting surface or flange E, and in this flange.is a recess F, in which
works part of the ring or traveller G, the ring or the traveller having been
placed in the recess F, the tube D, is lowered and brought onto the surface H,
of the cap. The tube D, is formed at the bottom with a projecting flange I, and

page_text: recess J, which are brought down over the upper surface of the body of the ring
or traveller and keep the ring or traveller in working position. The tube D,
increases the weight of the cap and causes a steady and regular action thus
producing better spinning and twisting at an increased speed. It is obvious that
the length and weight of the metal tube which is passed over the cap may vary in
length and thickness according to requirements.
The wire rings or travellers G, are made with hooks, eyes or twirls K, and the
strength and thickness of the wires forming the rings and hooks of the travellers
vary according to the different counts of the yarn to be produced and according as
more or less drag is to be given. In spinning, doubling and twisting the yarn
passes from the hook, eye or twirl of the wire ring or of the traveller to the
bobbin M, or to the spool producing an uniform drag on the yarn. winding onto
the bobbin or spool, wrapping in the loose projecting fibres of the yarn and effecting
a more regular spinning and twisting with an increase of speed when compared
with ordinary cap spinning.
Having thus described our improvements and the best means we are acquainted
with for carrying the same into effect we would have it understood that we do not
confine ourselves to the precise details shewn and described as they may be varied
without departing from the particular character of the invention but what we do
claim is:
.
Firstly. The improved "caps" for spinning, doubling and twisting machinery
constructed and operating in the manner and for the purposes substantially as
hereinbefore described and represented in the several figures of the accompanying
drawing.
Secondly. Constructing "caps" with a recess as described for carrying a ring or
traveller in the manner substantially as herein before described and represented in
the accompanying drawing.
In witness whereof I the said John Henry Clapham for and on behalf of
myself and the said Thomas Rochester Whitehead and Thomas Whitfield
Wheelwright have hereto set my hand and seal this first day of January in
the year of our Lord one thousand eight hundred and eighty four
