I JOHN REED MILSON, of Newton, Massachusetts, United States of America,
Mechanic 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 :-.
My invention relates more especially to the class of cop spindles employed in the
manufacture of worsted fabrics, and consists in certain novel features, hereinafter
fully set forth and claimed, the object being to produce a more effective and
otherwise desirable device of this character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all
conversant with such matters from the following explanation.
In the accompanying drawings
Figure 1 is a side elevation of my improved spindle with the bobbin and guard or
cap removed, a portion of the lifting and bolster rails being also shown in elevation.
Figure 2 is a vertical longitudinal section of the same taken lengthwise of the rails,
the bobbin and guard being shown in position for use, and the spindle proper
represented in side elevation.
Figure 3 is an enlarged vertical section taken crosswise of the rails, or at right
angles to the plane of the section in Figure 2, the spindle proper being shown in side
elevation and broken off, and the bobbin and guard removed.
Figure 4 is a horizontal section taken on line xx, in Figure 3, certain parts being
shown in plan view.
Figure 5 is a side elevation of the guard or cap detached.
Figure 6 is a bottom plan view of the bobbin; and
Figure 7 is a top plan view of the absorbent packing ring.
Like letters and figures of reference indicate corresponding parts in the different
figures of the drawings.

page_text: A represents the spindle proper. B the bolster rail. and C the lifting-rail.
A step D, is secured vertically in the bolster-rail by a screw d, said step being
provided with a screw-threaded hole a, in its bottom and enlarged at its top to form
an annular oil-cup b, which rests on said rail.
The walls of the step rise above the bottom of said cup, and are provided with holes
or ducts, through which the oil passes from the bottom of the cup into the chamber g,
of the body of the step. The cup is also provided with an opening h, in its top,
through which it may be filled.
The lower end of the spindle proper, A, is screw-threaded, as shown at j, and fitted
into a screw-threaded hole a, in the bottom of the step D. It is also squared, as
shown at k, to receive a wrench by which the spindle may be turned and thereby
adjusted vertically in said step.
A cylindrical boss i, is formed on the lower portion of the spindle proper which fits
tightly in the step D, a rubber packing-ring m, being placed around the spindle
below said boss to prevent the escape of the oil should any pass the boss from the
chamber g.
An absorbent packing-ring p, composed of felt or similar material, is placed around
the spindle proper at the upper end of the chamber g, and above the ducts f, said ring
being kept in position by the upper portion of the step D, and a space q, being left
between its ends which serves as a vent for said chamber.
A long tubular driving sleeve E, is disposed on the spindle proper, said sleeve
having two vertical grooves r, cut in its periphery to receive the inner ends of driving
pins, as hereinafter described.
A whorl or pulley F is secured to the lower portion of the sleeve E, and rests on
the top of the cup b, said pulley being provided with an annular projection t which
extends downwardly into said cup and works in close contact with the top of the body
of the step D, without bearing thereon, said sleeve being so adjusted with respect to
said pulley that its lower end will be in contact or nearly in contact with the absorbent
packing-ring p, when in use.
A long tubular bobbin-sleeve G, is fitted to slide on the driving sleeve E, said
bobbin-sleeve being provided at its lower end with an annular base plate H, on which
the bobbin or spool I, rests, and said plate provided with upwardly projecting driving
studs V, which engage recesses or slots w, in the head of the bobbin when mounted
thereon.
The plate H, is secured to the bobbin-sleeve G, by pins 26, which extend into the
grooves r, in the driving-sleeve E, and thus subserve as driving-pins.
An annular socket is cut in the lifting-rail C, around the driving-sleeve E; and
fitted into this socket there is an inverted cup-shaped cap J, provided with air-
holes in its sides and a hole in its bottom through which the spindle proper and
sleeve E, pass.
The plate H rests on the cap J, and is provided on its lower side with an annular
flange 24, which extends downwardly into said cap, said flange serving to centre the
cap in the socket z, and keep it out of contact with the sleeve E.
An absorbent ring K composed of felt or analagous material, is placed around
the sleeve, E, within the cap J, said ring serving to absorb the surplus oil, if any,
taken up by the revolving sleeves, and enable it to be reused in fubricating said
sleeves.
A guide sleeve L, is rigidly secured by a rivet 25 to the upper portion of the
spindle A, said sleeve serving to prevent undue vibrations of the bobbin sleeve G,
which is fitted to slide freely thereon.
The upper end of the spindle proper is tapered, as shown at 27, and enters a corre-
sponding hole in the top of the thimble-shaped guard or cap M, the guard being
detachable from the spindle and of sufficient size to freely receive the hobbin I.
The upper end of the guide sleeve L, is provided with an annular flange, 28, for
preventing the bobbin-sleeve G, from being withdrawn from the spindle in doffing.
It will be obvious from the foregoing that the spindle proper A is stationary, and

page_text: that the driving sleeve E, and pulley F, rotate, but do not rise or fall with the lifting-.
rail C; also that the cap J, plate H, sleeve G and bobbin I, are raised and lowered
by said lifting-rail.
In the use of my improvement, the oil 30, is poured into the cup until the
chamber is filled therewith, and it stands on a level or nearly so with the top of the
body of the step D thereby saturating the absorbent ring p.
The bobbin I, is then placed on the bobbin sleeve, G, and the cap M, on the top
of the spindle A, and the frame started up in the usual manner, it being understood
that the pulley F, is supplied with a suitable belt whoroby the sleeve E, is caused to
rotate as the frame runs.
The frame being started up, as described, and the driving sleeve E rotated, the
hobbin-sleeve G, and bobbin I, will also rotate, and as the lifting-rail O, risos and
slides the sleeve G, upward on the sleeve E, and guide-sleeve L, it will tend to produce
a vacuum between the spindle and sleeves which, in conjunction with the centrifugal
action of the sleeves E and G, will draw the oil upward from the chamber 7, and
lubricate the parts in a manner that will be readily understood by all conversant
with such matters without a more explicit description.
To lubricate the inner walls of the lower or driving-sleeve E, where they bear on
the spindle A, it is necessary that air should be admitted to the cup b, to compensate
for the oil taken up by the said sleeve; but I have found that sufficient air for this
purpose will usually pass between the pulley F, and cup when the machinery is
running. I have also found that in order to have the oil discharged properly from
the upper end of the sleeve E, to lubricate the bearing surfaces between the sleeves G
and E, and G and L, it is necessary to admit air beneath the sleeve G; but I have
also found that sufficient air for this purpose will not readily pass between the
plates H, and cap J, more air being required than for the sleeve E, as the sleeve G,
slides on the sleeve E, in addition to being rotated, whereas, the sleeve E, has rotary
movements only; and hence I provide the vent or draft holes y in the cap J, which
fully meet this requirement.
The grooves in the sleeve E, for receiving the coupling or driving pins 26,
subserve a very important purpose both as channels for the oil and flues for the
air, enabling the sleeves to be lubricated much more effectually than it could be
conveniently accomplished if they were coupled in any other manner.
It is not,
however, necessary to employ two grooves, one being sufficient.
The boss i, on the spindle A, serves to steady the spindle in the step D, and also as
a bottom to the oil-chamber 9.
The absorbent packing-ring p prevents the oil from becoming drawn froin the
chamber g, with greater rapidity than is required to lubricate the parts, as it would
be were said ring not used.
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,
First, The combination of the following instrumentalities, to wit: a bolster-rail;
a spindle step secured in said rail and provided with an oil-cup; a spindle secured
in said step; a driving sleeve mounted on said spindle above said rail and provided
with a longitudinal groove or grooves and with a driving pulley; a lifting rail
disposed above said bolster-rail; a bobbin sleeve mounted on said driving-sleeve
above the lifting-rail and provided with a plate for supporting the bobbin; means
for coupling the bobbin and said plate; means for coupling the driving sleeve
and bobbin sleeve; and a guide sleeve secured to the upper portion of said spindle
for preventing the hobbin-sleeve from vibrating substantially as described.
Second, The combination of the spindle A, the driving sleeve E mounted thereon
and provided with the groove r, and pulley F, the bobbin-sleeve G, mounted on the
sleeve E, and provided with the plate H, coupling-pins 26, and stud ; the guide
sleeve L, secured to the spindle A, and cap M, mounted on said spindle; the rails B, C,

page_text: and an oil-cup for supplying the spindle and sleeves with oil, substantially as set
forth.
Third, The improved device herein described, the same consisting essentially of the
spindle proper A, stop D, sleeves E, G, L, pulley F, plate H, stud v, pin 26, cap J,
guard M, felt K, absorbent ring p and rails B, C, constructed, combined and arranged
