PROVISIONAL SPECIFICATION.
Improvements in or relating to Ring Spinning and Doubling
Spindles.
We, RICHARD CRABTREE of 51 Lena Terrace, Foreman Spindle Maker, and
JOHN HARGREAVES of 151 Deane Church Lane, Spinning Overlooker, both of
Bolton in the County of Lancaster, do hereby declare the nature of our said
invention to be as follows:
This invention refers to improvements in or relating to ring spinning and
doubling spindles and consists in means for stopping the spindle, holding the same
in position, allowing the spindle to be removed, and in an unique method of
lubricating the footstep carrying the same. To the spindle rail is secured the
bolster by means of nuts underneath, below which is the footstep for carrying the
spindle. The bolster is provided with a collar which sits on the spindle rail, and
When it is
the collar is fitted with a pivoted arm with a projecting end and lever.
desired to prevent the spindle lifting the projecting end is placed over the flange of
the driving wharve. To stop the spindle, for any desired purpose, the pivoted arm
is provided on one side with a brake consisting of leather or other pliable material
to operate against the wharve when turned in one direction, and when the arm
is turned in the opposite direction the spindle may be removed from the bolster
at will. The arm is held in the three positions by a spring operating on the
flat sides of the collar or base of the said arm, the said spring being attached
to the side of the bolster collar. The outside of the footstep portion of the
bolster below the spindle rail is provided with a hollow dish or cup to receive
lubricant, which flows to the spindle foot through holes leading therefrom. To
protect the lubricant from "fly," "fluff," and other imperfections a cover or covers
is provided, being secured to the bolster by a spring ring or rings fitting in a groove
or grooves.

COMPLETE SPECIFICATION.
Improvements in or relating to Ring Spinning and Doubling
Spindles.
We RICHARD CRABTREE of 51 Lena Terrace, Foreman Spindle Maker, and
JOHN HARGREAVES of 151 Deane Church Lane, Spinning Overlooker, both of
Bolton in the County of Lancaster, 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 and accompanying drawings:-
Our said invention relates to ring spinning and doubling spindles and consists in
-

page_text: improved means for holding the spindle in position or permitting its ready removal;
for applying a brake to the wharve, and also in improved arrangements for
facilitating the lubrication of the footstep.
The invention will be best understood by a reference to the annexed sheet of
drawings which illustrate the respective points constituting our invention.
Fig. 1 is a side view partly in section of the lower portions of a spindle to which
our improvements are shown applied.
Fig. 2 is a view at right angles to Fig. 1.
Figs. 3, 4 and 5 are plans which respectively show. the holder-down in three
different positions.
Referring to the said drawings, the spindle is marked a and. the,,wharve b.. The
spindle bolster c is secured to the rail din, the ordinary manner by a nut e. Upon
the collar of the bolster we pivot the improved holder-down f. The pivot f¹ passes
through the collar and is rivetted at the lower side of the collar so as to prevent
the part from lifting. The upper part of the holder-down projects at so as
to extend over the flange on the wharve b, when the holder-down is in the
position shown in Figs. 1 to 4. This projection f' prevents the spindle. from
being lifted during doffing. The holder-down f is also furnished with a brake
surface or pad f³ of leather or other suitable material let into the part f and so
situated that when the part is turned into the position shown in Fig. 4 the
pad is brought in contact with the flange of the wharve. The spindle can
thus be braked and stopped. The pivotted part of the holder down is formed
of a cam shape f* as clearly shown in the plan views Figs. 3, 4 and 5. In
conjunction therewith we apply a spring g to the periphery of the bolster collar
and so as to press with an elastic pressure upon the surface of the cam.
The
normal tendency of the spring g is to keep the part fin the holding down
position shown in Figs. 1, 2 and 3. When the holder-down f is turned round
into the position shown in Fig. 4 so as to brake the spindle, it is turned against
the pressure of the spring, and on being released the spring will fetch it away.
When the holder-down is turned round into the position shown at Fig. 5 the
projection is turned clear of the flange b' on the wharve and the spindle can
then be lifted out of the bolster. When in this position the holder-down is held
by the spring until again manipulated and replaced in, its holding down position.
The different faces of the cam f as clearly seen from the plan views Figs. 3, 4
and 5 in conjunction with 'the spring g bring about the described results.
The footstep portion of the bolster below the spindle rail is provided with and
surrounded by a hollow dish or cup i containing lubricant which finds its way to
the spindle foot through apertures h in the side of the footstep. As means for
securing these oil cups i in position we recess the nut e and form a groove therein
into which we spring a snap ring k or its equivalent. The top of the oil cup i' is
reduced so as to enter the recessed nut and we also groove the said reduced top so
that when thrust up into the nut the spring ring k or its equivalent snaps into the
groove in the top of the oil cup and retains it firmly in position. We are aware
that previous to the date of our Specification, oil cups have been attached to the
nuts of the footstep bolsters of spindles by means of spring snap rings, but in
these prior cases the snap ring and groove have been on the outside of a turned
extension of the nut the internally grooved oil cup being slipped over and snapped
upon this nut extension. In our invention however as will be seen from Fig. 1
no extension of the nut is required the snap ring and groove being in the inside of
the nut and the reduced top of the oil cup turned and grooved so as to snap into
the internal recess in the nut.
This arrangement is of importance as preventing the displacement and leakage of
the oil which takes place under the old arrangements.,
To protect the lubricating cup from "fly," "Huff" and dirt we might apply a
cover such as indicated by dotted lines to the outside of the nut e. This might be
formed as a part of the nut or it might be sprung on with a snap ring as indicated.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is,
1. The combined holder-down and brake for application to ring spinning and
doubling spindles substantially as described and shown.
2. The improved combined holder-down and brake for use in conjunction with
ring spinning and doubling spindles and consisting of the part f fitted with a brake
pad and pivotted to the bolster collar and having a projection which confines the
flanged wharve when the part fis in its holding-down or braking position, or leaves the
wharve free when turned into its releasing position, in combination with the indicated
cam and spring, all arranged and acting in the manner, for the purposes, and
substantially as described and as illustrated.
3. The improved method of applying an oil cup to the footstep of a spindle in
which the bolster nut is internally recessed, grooved and furnished with a spring
snap ring or its equivalent while the top of the oil cup is reduced and similarly
grooved so as to enter and snap into the interior of the recess in the nut substantially
as described and shown.
4. The cover for protecting the oil cup from dust and fly substantially as
described and as indicated in dotted lines in Fig. 1 of the drawings.
