Improvements in or relating to Spinning and Doubling Spindles.
We, RICHARD CRABTREE of 51 Lena Terrace, Foreman Spindle Maker, and
EDWARD GILLOW of 1 Raby Street, Foreman Fitter, both of Bolton in the
County of Lancaster, do hereby declare the nature of our said invention to be
as follows:-
This invention relates to improvements in spinning and doubling spindles having
loose or movable inside bearings, also to spindles with fixed bearings. For
spindles with loose or movable inside bearings we provide the upper end of the
inside bearing with a groove in which we mount a metallic wire or other suitable
elastic ring or its equivalent, which ring also fits in a corresponding groove in
the upper end of the spindle pillar, by which the loose or movable inside
bearings will be secured in position to prevent the same being displaced when
removing the spindle therefrom. For the purpose of oiling or lubricating the
spindle without taking the same out of its bearings, and without removing the
driving band from the wharve, we bore the bottom of the outside or spindle
pillar large enough to insert an oil cup; the outside diameter of the latter being
equal to the diameter of the bored portion of the outside or spindle pillar. The oil
cup consists of an inside cup and an outside bearing combined, provided with a cap
or cover secured by a spring ring or its equivalent mounted in a groove in the
upper end of the outer casing of the oil cup. This cap or cover is screwed on the
outside of the spindle pillar, by which the oil cup is protected against fly, fluff, and
other imperfections. The inside of the oil cup is bored out larger at its upper end
than at its lower end, and is provided with grooves to allow the oil or lubricant
more space in lieu of grooves on the inside bearing. The oil or lubricant is placed
in the inside oil cup and is forced upwards until it reaches a groove in the spindle
pillar nut or screwed end which holds the oil cup in position. By this method of
construction the oil or lubricant is forced out of the inside oil cup round the inside
bearing until it reaches the top of the inside spindle bearing, thus entirely pre-
venting the exposure and escape of oil or lubricant. In case of spindles with fixed
bearings the bottom end of the spindle pillar is provided with an oil-box and
passages to the interior of the said pillar to lubricate the spindle. The inside of
the spindle pillar is made sufficiently large in diameter to allow of oil or lubricant
being forced upwards from the oil-box on inserting the spindle as is the case with
spindles with loose or movable inside bearings. For the purpose of facilitating
spinning on paper tubes we provide the upper end of the spindle with a tapered
wood or other pirn, loosely mounted between the spindle sleeve and an iron pirn
secured to the top of the spindle. The object of this loosely mounted taper pirn
is to prevent the buckling of the spindle, and yarn being wound round the spindle
when piecing the ends take place. By making the pirn continuously taper from
bottom to top the paper tube can be easily removed without damage to yarn or
spindle. For the purpose of stopping the spindle when necessary for "doffing,"
and other purposes we employ a brake, consisting of a sliding bar operated by a
pivoted lever mounted on a rail in close proximity to the wharve. The sliding bar
is provided on its operating face with leather or other suitable substance or material
that will easily grip and arrest the rotating action of the wharve and spindle.

Improvements in or relating to Spinning and Doubling Spindles.

EDWARD GILLOW of 1 Raby Street, Foreman Fitter, both of Bolton in the
County of Lancaster, do hereby declare the nature of our said invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-

Fig. 7 is a sectional elevation of our invention with fixed bearings.
Fig. 8 is an outside elevation of spindle pillar in Fig. 7.
Fig. 9 is an outside elevation of oil or lubricant cup, and
Fig. 10 is a plan of Fig. 9.
In all the figures the same letters are employed to indicate corresponding parts.
A is the spindle; B the spindle pillar; C the spindle sleeve; D the wharve,
and E the spindle rail. The upper end of the loose or movable inside bearing G is
provided with the groove J in which is mounted the metallic wire or other suitable
elastic ring H or its equivalent as shown in Fig. 1. The ring H also fits in a
corresponding groove in the upper end of the spindle pillar B, by which the loose
or movable inside bearing G is secured in position to prevent the same being
displaced when removing the spindle A therefrom. The loose or movable inside
bearing G is provided with the longitudinal slots I, holes K, and passage L for oil
or lubricant. To ensure of the loose or movable bearing G maintaining or assuming
its correct position in the spindle pillar B and to prevent the same rotating with the
spindle A it is provided with the pins M fitting in vertical slots in the upper end of
spindle pillar B. The latter is secured to the spindle rail E by the nut N screwed
on the lower end of spindle pillar B.
For the purpose of oiling or lubricating the spindle A without taking the same
out of the loose or movable bearing G and without removing the driving band from
the wharve D the bottom end of the spindle pillar B is bored large enough to
receive the inside cup P of the oil or lubricant cup, the outside diameter of the
same being equal to the diameter of the bored portion of the spindle pillar B. The
oil or lubricant cup consists of the inside cup P and the outside casing or bearing ()
combined. The inside cup P is bored taper and is larger in diameter at its upper
end than at its lower end, and is provided internally with the grooves S¹, as shown
in Figs. 5 and 6, to allow the oil or lubricant therein more space to expand
and prevent flush and to cause an even or steady upward flow of same in the
cavity V when the loose or movable inside spindle bearing G and spindle A
are placed in position therein. The internal upper end of the outer casing O
is grooved and fitted with the spring ring Q or its equivalent, by which it is
secured in position on the shoulder R on the lower end of the nut N forming
the cap or cover and screwed on the lower end of the spindle pillar B, thus
securely enclosing the oil or lubricant cup and protecting its contents from "fly,"
fluff," and other imperfections met with in spinning rooms.
Between the upper
end of the inside cup P' and the shoulder S in the spindle pillar B is disposed
the ring T composed of cork or other suitable material or substance to form a
joint. After the oil cup has been secured in position on the shoulder R of the
nut N by the spring ring the inside cup P is supplied with oil or lubricant,
which on the insertion of the loose or movable inside spindle bearing G and
spindle A forces a portion of the oil or lubricant therefrom, according to the
amount of displacement by the said bearing G, from whence the oil or lubricant
rises up the space or cavity V between the outside of the bearing G and the inside
of the spindle pillar B, also up the longitudinal slots 1 on the outside of the
bearing G. thus entirely preventing the exposure and escape of oil or lubricant.
The latter is supplied from the space or cavity V to the spindle A as required by
means of the holes K in the slots I and the passage L in close proximity to the
footstep in the bottom end of the loose or movable inside spindle bearing G. In
case oil or lubricant is raised by capillary attraction by the spindle A until it runs
over the top end of the loose or movable inside bearing G it will flow back down
the slots I to the level of the oil or lubricant in the space or cavity V or in the
inside cup P.
In adapting our improvements to spindles with fixed bearings the outside bottom
end of the spindle pillar B is threaded to receive the nut N; the lower end of the
latter being provided with the shoulder R for the purpose of carrying the oil or

page_text: lubricant cup by means of the spring ring Q in the upper end of the outer casing O
as shown in Fig. 7. The lower end of the spindle pillar B is provided with a
central projection or fixed bearing G having a chamber or cavity between its
external diameter and the internal diameter of the outside bottom end of the spindle
pillar B. the inside cup P of the oil box fits in the said chamber or cavity leaving a
space for oil or lubricant. The inside cup P in this case also is bored taper and is
larger at its upper end than at its lower end, and is provided with the grooves S',
as shown in Figs. 9 and 10, to allow the oil or lubricant therein more space to
expand and to effect an even upward flow of same in the cavity V when the fixed
bearing G and spindle A are inserted therein. The central projection or fixed
bearing G forms the footstep for the spindle A; the latter being held vertically by
the bush W in the upper end of the spindle pillar B. In the bottom end of the
central projection or fixed bearing G are disposed the passages L to admit oil or
lubricant from the inside cup P. Between the footstep and the bush or bearing W
in the spindle pillar B is formed the chamber or cavity V up which is forced the
oil or lubricant when the bearing G and spindle A are placed in the inside cup P.
For the purpose of facilitating spinning on paper tubes the spindle A is fitted
with the tapered wood or other pirn Y, loosely mounted between the upper end of
the spindle sleeve C and the iron washer Z fixed to the top of the spindle A. The
object of the loosely mounted taper pirn Y is to prevent the buckling of the
spindle A, and the winding of yarn round the same when piecing yarn is being
performed. By constructing the pirn Y continuously taper from bottom to top
paper tubes can be readily removed therefrom without damaging the yarn or
spindle.
To facilitate stopping the rotative action of the spindle A and its adjuncts when
necessary for "doffing" and other purposes we employ a brake consisting of the
sliding bar A¹ mounted in the fixing B₁attached to the spindle rail E. The sliding
bar A¹ is operated against the wharve D by the lever C¹ pivoted to the fixing BI.
The lever C is located so that the attendant can operate the same by simply
pressing against it with the knee or otherwise; and the sliding bar A' is mounted
so that as soon as the lever C is released from pressure it will slide back, auto-
matically of its own weight and that of the lever C', which will be fully understood
by referring to Fig. 2 of the drawings. The operating face of the sliding bar A
may be covered with leather or other suitable substance or material that will
effectively grip and arrest the rotating action of the wharve D on the spindle
sleeve C.
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. In spinning and doubling spindles provided with either movable or fixed inside
bearings, the use of an outside cover and an inside tapered oil or lubricant cup
combined; the upper end of the latter bearing against a pliable substance in the
spindle pillar to form a joint to prevent oil or lubricant descending into the outside
cover, and to ensure of the oil or lubricant being forced upwards; the inside cup
having internal grooves to allow the oil or lubricant therein more space to expand
and prevent flush, and to cause an even and steady flow of same in the cavity or
space between the outside of spindle or spindle bearing and the inside of spindle
pillar, substantially as described.
2. In combination with loose or movable inside bearings employed in spinning
and doubling spindles, the use of a metallic or elastic ring mounted in a groove
in the upper end of the inside bearings and a groove in the upper end of the spindle
pillar for the purpose specified, substantially as described.
3. In combination with spinning and doubling spindles the use of a tapered wood
or other pirn loosely mounted between its support and a washer fixed on the
top end of spindle, substantially as described and for the purposes herein set
forth.

page_text: 4. In combination with spiuning and doubling spindles the use of a brake con-
sisting of a sliding bar mounted diagonally in its support and operated by a
lever; the said brake sliding back automatically by its own weight and that of
the combined action of the operating lever immediately the latter is released
from pressure, substantially as described.
