IMPROVEMENTS IN EFFECTING THE DRAG IN CAP SPINNING to bo as
follows:-
"
Our improvements consist in supporting flat rings, in a perfectly horizontal
position, immediately under the bottom edges or the flanges formed on the bottom
edges, of caps, used in spinning, whereby the drag is effected in the passage of the
yarn between the bottom edges, or flanges of the caps, and the flat rings - herein-
before mentioned.
To carry out our improvements we construct flat metallic rings of similar
diameters to the bottoms of the caps with which they are to operate.
These flat rings are each supported by two pins forming an axis by and upon
which the rings are carried by means of a fork or holder which is balanced by a
tail piece, working upon a centre between the two arms of an L shaped bracket
projecting horizontally from a flat rail to which it is attached and which rail is
fixed across the front of the spinning frame, immediately behind the spindles.
To prevent the before mentioned flat rings from assuming a vertical, instead of
a horizontal position, when the caps are removed each flat ring has a hole drilled
horizontally through its back into which hole projects and fits loosely a short pin,
or stud fixed in the fork or holder before mentioned.
The forks or holders are pressed upwards, carrying with them the flat rings, by
means of flat springs, pressing upon their underside, and regulated to any desired
pressure by set screws, fixed under such springs.
The pressure of the flat rings upon the yarn passing between such flat rings, and
the lower edges or flanges of the caps, can by these means be adjusted to obtain the
desired drag or tension, upon the yarn being operated upon.
Instead of the L shaped brackets, carrying the forks or ring holders, as heroin-
before described, I sometimes use flat steel springs also made L shaped and fixed
by one of their arms to the flat rail hereinbefore referred to, fixed across the front

or tension put upon the yarn, in passing between the flat rings, and the bottom 5
edges or flanges of the caps, can be regulated and adjusted to great exactness, by
set screws, pressing against the under side of the springs.

page_text: We, JOHN HENRY CLAPHAM of 46 Thompson Street, Shipley, in the County of
York, Mill Overlooker, and THOMAS WHITFIELD WHEELWRIGHT of Manchester
Road, Bradford, in the same County, Manufacturer, do hereby declare the nature of
our invention for IMPROVEMENTS IN EFFECTING THE DRAG IN CAP SPINNING" and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:
Our improvements consist in supporting flat rings in a perfectly horizontal
position, immediately under the bottom edges, or the flanges formed on the bottom
edges of caps, used in spinning, whereby the drag is effected in the passage of the
yarn between the bottom edges or flanges of the caps and the flat rings hereinbefore
mentioned.
To carry out our invention we construct flat metallic rings, of similar diameters
to the caps with which they are to operate. These flat rings are each supported
by two pins, forming an axis, by, and upon which, the rings are carried by means of
a fork or holder, which is balanced by a tail-piece working upon a centre between
the two arms of an L shaped bracket, projecting horizontally from a flat rail to
which it is attached and which rail is fixed across the front of the spinning frame;
immediately behind the spindles. To prevent the before mentioned flat rings from
assuming a vertical instead of a horizontal position, when the caps are removed,
each flat ring has a hole drilled horizontally through its back, into which hole
projects, and fits loosely, a short pin or stud fixed in the fork or holder before
mentioned. The forks or holders are pressed upwards, carrying with them the flat
rings by means of flat springs, pressing upon their under side, and regulated to any
desired pressure by set screws fixed under such springs. The pressure of the flat
rings upon the yarn passing between such flat rings and the lower edges or flanges
of the caps can be by these means adjusted to obtain the desired drag or tension
upon the yarn being operated upon.
Instead of the L shaped brackets carrying the forks or ringholders, as herein-
before described we sometimes use flat steel springs, also made L shaped, and fixed
by one of their arms to the flat rail herein before referred to, fixed across the front
of the spinning frame, the said flat springs having at the termination of their other
forks for the purpose of carrying the axis of the flat rings, in a similar manner
to the forks or ring-holders hereinbefore described.
arms,
The upward pressure of the horizontal arms of these L shaped springs, and
consequently the amount of drag or tension put upon the yarn in passing between
the flat-rings and the bottom edges or flanges of the caps, can be regulated and
adjusted to great exactness by set-screws pressing against the underside of the
springs.

which it is supported..
Figure 3. a perspective view of the same.
Similar letters refer to similar parts in all the drawings.
A represents an ordinary spinning cap, close to the bottom edge of which is 6
supported the ring B, between which ring and the bottom edge of the cap the
yarn represented by the dotted line L passes on its way to the bobbin M.
The ring B has two pins or pivots Cupon which it is supported in the fork of
the spring or holder E.
A small hole in the ring B at the point D admits the end of the wire K which I
projects into, but does not fit tightly, in the hole D, as a certain amount of play is
required.
The L shaped spring or holder E is bolted to the cross-rail G which extends
across the front of the spinning frame, behind the spindles. The spring or holder E,
and with it the ring B, can be raised or lowered to the greatest nicety, by means of 1
the set screw H, which when adjusted is made fast where required by the check
nut J.
The ring B is not held rigidly in position close to the bottom of the cap A, but
has sufficient play in its bearings to allow it to accomodate itself to the motion
of the yarn, passing over it.
-
In place of the spring E, for supporting-the-ring-B,-we-can_use_a_tail-piece
attached to the ring B, and carried by two pivots, whereby the weight-of-the-tail-
piece counterbalances the weight of the ring, and holds it up to the bottom of the
cap, in the same manner as the spring herein before described.

Having now particularly described and ascertained the nature of our said 2
invention, and in what manner-the-same-is-to-be-performed; we declare that what
we.claim is
The use of a ring, supported close under the bottom of a spinning cap, for the
purpose of effecting-the-drag-or-tension-upon-the_yarn passing between the ring,
and the bottom edge of the cap, and at the same time smoothing, and turning in 3
the loose fibres of auch yarn in the manner set forth, or any mere modification
thereof.
