COMPLETE SPECIFICATION.
Improvements relating to the Spindles of Spinning Machines and to
Supports therefor.
I, CHARLES HENRY CHAPMAN, of the Town of Groton, in the County of Middlesex
and State of Massachusetts, United States of America, gentleman, 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 :—
My invention relates to spinning spindles and supports therefor, generally, and
particularly to that class of spindles and spindle supports which enable the spindle to
find its true centre or axis of rotation, and therefore to be accomodated to its load.
It is the object of my invention to provide such improvements in the class of
spindles mentioned as will overcome defects and objections existing in present
structures, and also to provide means whereby the spindle and spindle bearings may
be readily and efficiently lubricated, all as hereinafter described and pointed out in
the appended claims.
Of the drawings hereunto annexed and forming a part of this specification, Figure 1
is a sectional view (showing a portion of the spindle in elevation) of the sleeve whirl,
bolster rail, bolster case, spindle bearings and lubricating cups. Fig. 2 is a side view
of the shell for supporting the bolster bearing and step, and the support for said shell.

The same letters of reference designate the same parts or features, as the case may
be, in all of the views.
e,
In carrying out my invention (having reference to Figures 1 to 4* inclusive) I
provide a suitable bolster case a, preferably provided on its upper end with an oil
cup, and secure said bolster case to the rail c by means of a suitable nut d.
e designates a shell arranged in the bolster case and sustained therein by means of an
elastic support, extending up from a ring or thimble g secured in the bolster case a.
designates the bolster bearing arranged in the upper portion of the shell and
secured thereto and therein by means of a rivet i which passes through the bolster
bearing h, shell e and elastic support f, as shown in Fig. 1. The point at which the
elastic support f, the shell and the bolster are secured together is desirably (though
not necessarily) central of the sleeve whirl j, so as that such point shall be substan-
tially on a line with the band pull. Instead of employing the rivet i to secure the
elastic support f to the other parts, I may use solder or other suitable uniting means.
The shell e extends down through the open bolster case a, the boro in the latter
being sufficiently large to allow of limited lateral movement of the shell without
contact with the interior of the bolster case. k designates the step secured in the
lower end of the shell and in or upon which the foot of the spindles rests, said
spindle extending from the step up through the shell and through the bolster bearing,
and running in contact with the latter but not touching the former.
I have herein shown the interior of the upper portion of the shell e as provided
with an offset 1, and the exterior of the upper end of the holster bearing as provided

page_text: with a shoulder m arranged to rest on the offset ; I have also shown a practically
rigid guard n extending around the elastic support from the thimble y to, or near
to, the shoulder formed on the exterior of the shell é at the offset point I, which rigid
guard tends to keep the spindle and shell in an upright position and prevent the band
pull from unduly deflecting the spindle or drawing it out of centre with respect to
the ring, it being understood that the band pull is in a direction toward the rigid
guard n, as indicated by the arrow in Fig. 2.
These several parts and features may however be modified or entirely dispensed
with, without departing from the nature or spirit of my invention. Concerning
changes that may be made in the form of the devices specified, it may be mentioned,
for example, that the shell and bolster support may be constructed as shown in
Figures 5 and 6, wherein the thimble g is represented as provided with a plurality of
elastic supports or spring tongues ffi and a rigid guard Said elastic supports
and rigid guard extend up to, and on practically opposite sides around, the bolster
bearing, one of said elastic supports being riveted or soldered or otherwise secured to
the bolster bearing as before described, rigid guard subserving the functions accom-
plished by the rigid guard n, shown in Figures 2 and 3.
With this construction the shell carrying the bolster bearing and step, being
sustained in position by the elastic support for f, is permitted to yield to ac-
comodate the spindle to its load; at the same time the tension of the elastic support f
being in the direction of the arrow, Fig. 2, and the pull of the band being in the
same direction, the shell is kept from undue deflection from a vertical line by the
rigid guard n, which construction and arrangements of parts also tends to maintain
the spindle in vertical position, and to all intents and purposes in the centre of the
ring.
Again, the support for the shell e may be constructed and arranged as shown in
Figures 12 to 14 inclusive. In this instance the shell support consists of compara-
tively narrow strips of metal extending between the thimble g, and a ring, and
"set down" to form the angular or V-shaped portions, to permit of slight motion
vertically of the spindle. In this latter instance the rigid guard f extends upward
from the thimble g to, or nearly to, the ring g², and the several parts will be arranged
and operate as before described, excepting that the spindle, in addition to being
allowed lateral play may have slight vertical motion as well, the V-shaped portion of
the shell providing for this latter function.
o designates an oil cup, which may be spun up from a blank of sheet metal and
sprung upon the lower end of the nut d, so that its edges will snap or catch into
notches formed in ears g of said nut, by which an open top cup is provided adapted
to receive oil and supply the same to the step and other bearings of the spindle
through the aperture in the shell. designates a cover or rim adapted to be sup-
ported on the nut d above the cup o to keep dust and dirt from settling or falling into
the cup, said rim being partially cut away, as at ss, so that it may be arranged over
the cars and closely down on the top of the cup; at the same time it is so
constructed and arranged as to be adapted to be slipped upon the neck of the
nut to allow of oil being supplied to the cup.
The shell e may be extended above the bolster bearing h so as to form an oil
cup thereabove, as at t. A hole is formed in the bolster casing a leading from
the oil cup to the interior of the casing outside of the shell e, so that the oil
supplied to the spindle from the cup o through the aperture formed in the lower
end of the shell e, and by the rotation of the spindle carried up to the bolster
bearing, the latter being rifled on its interior surface, as is common, and filling and
flowing over the cup t, may drip down into cup b and flow back through the hole u
to the cup o to be again supplied to the spindle. A sleeve or apron w is connected
with the whirl and extends down into the oil cup b to conduct the overflowing oil
from the top of the spindle support into the oil cup b. designates a cover to oil
cup 6 to keep dust and dirt out of oil cup b.
y designates a stop pin of common construction, the office of which is to prevent
the spindle from being pulled out of its bearing in doffing the bobbin.
