Improvements in and relating to Spindles for Spinning and Twisting
Machines.
I, HENRY FRANCIS WOODMANCY, of Church Street, Whitinsville, in the
County of Worcester, State of Massachusetts, United States of America,
Machinist, do hereby declare the nature of my 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 has reference to an improvement in the construction of the
bearings and supports of spinning and twisting machine spindles.
The object of the invention is to so construct the step and bolster bearings for the
spindle and the spindle in connection with the bolster-case that these bearings shall
be thoroughly lubricated.
Another object of the invention is to so construct the spindle and the bearings
for the spindle that, when the spindle is running at the highest possible speed, the
lubricating oil, while circulating freely to lubricate the bearings, will not overflow
the bolster-case.
And another object of the invention is to simplify and cheapen the construction
of the spindle.
In spinning and twisting machine spindles, as heretofore constructed, the bolster
and step tube, in which the spindle is supported, is constructed to secure a capacity
for the spindle and its support to adjust themselves to unequal bobbins, or yarn
loads, by allowing the spindle and the supporting tube to move laterally, as a whole,
within the supporting case, or to adjust themselves axially by giving to either the
upper or the lower end of the combined bolster and step tube, or both, capacity for
lateral motion.
The object of such capacity in the spindle to change its vertical axis has been
to permit of the use of imperfect bobbins. I find that, in practice, when imperfect
bobbins are used on these spindles, imperfect, or uneven, yarn is produced,
particularly when yarn of the finer numbers is spun on ring-frames, and that to
produce the best results in spinning yarn on ring-spinning frames, the perpendicular
axis of the spindle must be in the exact center of the ring during the whole traverse
of the ring and that the bobbins must be, at all points, exactly concentric with the
vertical axis of the spindle.
I find that a properly constructed and proportioned spindle can be run, at the
highest speed yet attained in spinning yarn, in a fixed supporting tube, provided
the bearings are abundantly supplied with a continually changing flow of lubri
cating oil, and I have, therefore, constructed a combined bolster and step tube
rigidly secured in the bolster-case and have so constructed the spindle and its
support that the lubricating oil will circulate freely upward around the spindle and
downward around the bolster-tube.
The invention consists in the peculiar and novel construction of the bolster-case,
the combined bolster and step tube and the spindle, and the relation of each to the
others, as will be more fully set forth hereinafter.
Figure 1 is a vertical section through the center of the spindle.
Figure 2 is a side view of the combined bolster and step tube, the bore in which
is indicated in broken lines.
In the drawings the number 3 indicates the blade of the spindle, 4 the journal-
bearing of the spindle, and 5 the foot of the spindle. 6 indicates the bobbin-
bearing on the spindle, 7 the sleeve-whirl, and the clearer on the spindle.
9 indicates the flange on the bolster-case which rests on the bolster-rail and forms
the base of support for the whole structure. 10 is an oil-cup formed, above the

flange 9, around the upward projecting tube 11 of the bolster-case, which tube
extends above the clearer 8 on the spindle. The oil-cup is protected by a disk
The tube 12, closed at the lower end, extends below
the flange 9 and is provided with the screw-threads 13, so that, when the tube 12
is passed through the hole in the bolster-rail, the flange 9 resting on the top
of the bolster rail, the whole structure is firmly secured by a nut placed on
the threaded portion of the tube 12. The tube 11, oil-cup 10, flange 9, and
the tube 12, form the holster-case; this bolster-case is bored out so as to
form a cylindrical space of a diameter larger than the bolster-tube 14, so that
an annular space is formed between the bolster-tube and the bolster-case. The
bolster-tube 14 is bored out to form the bolster-bearing for the spindle and the
step-bearing. 15 for the foot of the spindle. The lower end of the bolster-tube 14
is provided with the conical pin 16, and the lower end of the tube 12 of the
bolster-case is provided with a conical socket 17 into which the pin 16 is driven,
so that the combined bolster and step tube is rigidly and firmly supported in the
bolster-case, concentric with the interior of the bolster-case, so as to form an
anular. space between the bolster-case and the bolster-tube. The oil-cup 10 is
connected with the interior of the bolster-case by one or more holes or ducts, and
the interior of the bolster and step tube is connected also with the interior of the
bolster-case by one or more holes or ducts.
The combined, bolster and step tube, consisting of the bolster-tube 14, the
step 15 and pin 16, is made and held in the bolster-case sufficiently rigid to resist
the normal strain of the band or belt, which passes around the whirl and by which
the spindle is driven, so that the vertical axial position of the spindle and the
concentric relation of the spindle and the bobbin to the ring will not be changed
and the ring of the ring-spinning frame will be practically concentric with the
spindle and bobbin at the higher as well as at all other points of its vertical
traverse.
The pin 18 is the usual pin used to prevent the spindle being raised in doffing.
The bore of the bolster-case is shown of uniform diameter from the top of the
tube 11 to the conical socket 17; this bore may be of larger diameter between the
oil-cup and the conical socket, as is indicated in broken lines, so as to form a larger
oil-chamber.
I find that when a spindle, constructed as herein shown and described, is run at
high speed in a ring-spinning machine, the spindle and bobbin not only maintain
their perfect relation with the ring, but the thumping, jarring, wobbling, and
uneasy motion, usual in spindles running at high speed, is entirely avoided, and
that this result is secured without the slightest change of the axis of the spindle or
its supporting bolster.
The lubricating oil is, when the spindle is running at high speed, forced upward
between the spindle and the bolster-tube and follows the spindle until it reaches
the clearer 8, surrounding the spindle, where the oil is thrown outward against the
interior of the boslter-case, the tube 11 of which extends above the clearer. As
previously constructed, the upper end of the bolster-case, was connected with the
lower portion by a groove, or grooves, formed in the outer side of the bolster-tube,
and, where the bolster-tube was of less exterior diameter than the interior diameter
of the bolster-case, such annular space was filled up and obstructed by packing,
springs, or other yielding devices, so that the lubricating-oil could not flow freely
downward, and, consequently, most spindles of these prior constructions throw off
considerable oil and thus keep the spinning-frame and the floor in an unclean,
unsightly, and dangerous condition, much objected to by fire underwriters, and also
injure the yarn by staining the same with oil containing rust and other impurities
difficult to remove in the subsequent processes to which the yarn requires to be
subjected.
By my construction an unobstructed annular space is secured between the
bolster-tube and the bolster-case, extending from the top of the bolster-tube to the
step of the spindle, and thereby so free a circulation of the lubricating-oil that no

page_text: oil can be thrown off by the spindle or raised above the bolster-tube. As the
whirl 7 extends down over and surrounds the tube 11 of the bolster-case, the strain
on the driving-band is at, or nearly at, the center of the journal-bearing of the
spindle, and, as this bearing has considerable length, the spindle may be made to
fit the bearing more loosely and such a spindle can be run with less strain than
when the whirl is placed above or below the bolster-bearing of the spindle.
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 :-
Claim 1. A spindle support, consisting of a bolster-case and a rigid bolster-tube
of less external diameter than the interior of the bolster-case, forming the bolster
and step bearing for the spindle and rigidly secured at its lower end in the bolster-
