Improvements in Machinery for Spinning and Twisting Wool,
Worsted, Silk, Cotton, and other Fibrous Substances.
I, DANIEL KNIGHT, of Wade Street, Bradford, in the County of York, Wool
Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to a new method of, and machinery or apparatus for,
producing or applying the twist and the drag to the yarn, in spinning and twisting
wool, worsted, silk, cotton, and other fibrous substances.
The objects of this invention are to prevent ballooning and doubling of the yarn,
increase the speed and thereby augment the production, economize space, and
lessen the requisite power.
The spindles, according to my invention, are made of smaller diameter than
usual (thus increasing the speed) and, being attached to the lifter, are preferably
operated by the lifting rod, although they may be raised and lowered by a boss on
each lifter plate. The tubes for receiving the bobbins are provided with the
usual wharles or whirls, around which the straps work.
Fixed to the longitudinal support for the roller stands (or rig-tree) is an
adjustable bracket, one for each spindle, carrying or cast in a piece with which
is a collar, provided on its inner lower periphery with a rim or lip, onto which is
placed a ring; and above this said ring is dropped or adjusted a loose sleeve,
within the aforesaid collar and protruding a short distance thereout above the
same. The bobbin rotates within the above named loose sleeve, ring, and
collar.
The yarn passes down inside the loose sleeve, over the outer periphery of the
ring, and inside the collar, to the bobbin; the friction or drag being increased or
lessened by providing heavier or lighter rings inside the aforesaid collar.
Dated this 6th day of July 1896.

Improvements in Machinery. for Spinning and Twisting Wool,
Worsted, Silk, Cotton, and other Fibrous Substances.
I, DANIEL KNIGHT of Wade Street, Bradford in the County of York, Wool
Merchant, 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 :-
This invention relates to a new method of, and machinery or apparatus for,
producing or applying the twist and the drag to the yarn, in spinning and twisting
wool, worsted, silk, cotton, and other fibrous substances,

page_text: The objects of this invention are to prevent ballooning and doubling of the yarn,
increase the speed and thereby augment the production, economize space, and
lessen the requisite power.
The spindles, according to my invention are made of smaller diameter than
usual (thus increasing the speed) and, being attached to the lifter are preferably
operated by the lifting rod, although they may be screw threaded at their ends
and supported and guided by a screw threaded boss on each lifter plate. The
tubes for receiving the bobbins are provided with the usual wharles or whirls,
around which the straps work. Fixed to the longitudinal support for the roller
stands (or rig-tree) is an adjustable bracket, one for each spindle, carrying or cast
in a piece with which is a collar, provided on its inner lower periphery with a rim
or lip, onto which is placed a ring; and above this said ring is dropped or adjusted
a loose sleeve, within the aforesaid collar and protruding a short distance thereout
above the same. The bobbin rotates within the above named loose sleeve, ring,
and collar.
And in order that the invention may be the easier comprehended I have
hereunto appended a set of drawings illustrative thereof, whereon,-
Fig. 1 represents a front elevation, partly in section, of part of a spinning
machine with the invention applied thereto.
Fig. 2 is a side view of a portion of Fig. 1, and
Fig. 3 is a plan of a part of Fig. 2.
Fig. 4 shows a modified form of the apparatus in plan,
Fig. 5 is a front end view and Fig. 6 a cross section of Fig. 4.
Fig. 7 is a side view showing the top plate hinged, and
Fig. 8 is a front end view shewing another method of supporting or guiding the
top plate.
A is one of the spindles secured by a screw thread and nut, for instance, to the
lifter B. These spindles A are, as preferred, operated by the lifter rod in the
ordinary way, although they may be supported or guided by a screw threaded boss
on each lifter plate, the spindles A being in this case screw threaded on the ends
which take into the screw threaded bosses. The tubes C for receiving the bobbins
are driven by straps working around the wharles or whirls D as usual. The top c
as well as the bottom inner portion of the tubes C may.contain a bearing or brass
adjusted or cast therein for the spindle A to work in, so as to prevent contact of
the rest of the spindle with the tube C, and thus reduce the friction and increase
the speed.
E represents the longitudinal support for the roller stand, or rig-tree, to which
the bracket F, one for each spindle, is fixed. This bracket F carries a collar F
(or the collar F1 may be cast in a piece with the bracket F) provided with a rim
or lip onto which is placed'a ring G. Above the ring G is dropped or adjusted a
loose sleeve H, in 'the manner shown. The parts F, G, and H are preferably made
of steel.
The yarn a passes down inside the loose sleeve, over the outer periphery of the
ring, and inside the collar, to the bobbin; the friction or drag being increased or
lessened by providing heavier or lighter rings inside the aforesaid collar.
As will be seen the invention is devised to obviate the necessity for employing
the usual cap.
But in practice I have found that I can with facility dispense with the loose
sleeve H, and lighten the weight of the apparatus, by adapting a thin plate or
disc Hx, as shown in Figures 4 to 8. above the ring G and in close proximity
thereto, though not actually touching the said ring G, in Figs. 4. 5 and 6. I have
shown the thin plate or disc H* as fastened by the screws h. h. h. but for greater
convenience for changing the rings G, it may be hinged to the part F. as shown in
Fig. 7. or I may employ two thin springs has shown in Fig. 8, for the
plate H*, to be raised and lowered on. In Fig. 7, I have shown the method
I prefer to use for bracketing the modified form of the invention to 'the
longitudinal support E. namely by the additional adjustable bracket F*. The

page_text: bracket F is provided with a gap, and the plate H* in the modification seen in
Figs. 4, 5, and 6, is likewise provided, for the purpose of adjusting the yarn about
the ring G; and his an adjustable guide for keeping the yarn in position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The improvements in machinery for spinning and twisting wool, worsted, silk,
cotton, and other fibrous substances substantially as described and shown in the
drawings.
2. The ring G. contained in the bracket or support F. for guiding the yarn in
the manner and by the means described and shown or any mere modification
of same.
