We JAMES HOGG and WILLIAM HOGG of Laurence, Massachusetts, United States
of America, Mechanics 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:-
Our invention relates to that class of spindles which are more especially designed for
worsted spinning and provided with flyers and it consists in certain novel features, as
hereinafter fully set forth by which a more effective and otherwise desirable device of
this character is produced 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 vertical longitudinal section of my improved spindle, certain parts
being shown in side elevation; and
Figures 2 and 3 sectional views showing certain modifications in the construction.
Like letters and Figures of reference indicate corresponding parts in the different.
Figures of the drawings.
A represents the spindle proper which is enlarged at the lower end to form the
tang m the said tang being spirally grooved as shown at a and secured in the
stationary rail B by a screw C in the usual manner.
The upper portion of the spindle A is reduced to form the pintle the said pintle
being inserted in a corresponding vertically arranged socket t formed in the lower end
of the cap-plug D, on which said plug is fitted to rotate.
A metallic sleeve E, is disposed on the body of the spindle A, the upper end of the
said sleeve being firmly secured to the cap-plug D, preferably by shrinking it onto
the same, and its lower end provided with a whorl or pulley H which is also firmly
secured to said sleeve.
.
The cap-plug projects above the sleeve E, its upper end being reduced to form the
shoulder g and exteriorly screw-threaded to fit a correspondingly screw-threaded hole
in the top of the flyer J, which is mounted thereon, as shown.
The upper end of the spindle A is drilled or bored vertically to form an oil duct K
the said duct being connected with two laterally projecting auxillary ducts bd, the

duct
opening outwardly into the upper portion of the sleeve E and the duct d
outwardly into the socket t of the plug-cap D.
The auxillary duct is inclined upward from its inner to its outer end, thereby
forming a pocket at the lower end of the main duct K adapted to hold a small
quantity of oil which is gradually withdrawn therefrom by capillary attraction and the
centrifugal action of the sleeve E thereby ensuring the lubrication of the sleeve for a
longer period than would be possible without said pocket.
An oil-duct 45, is formed in the cap-plug D, the said duct extending centrally from
the bottom of the socket t, diagonally upward and outward through the side of the
said plug, and connecting at its lower end with the upper end of the duct K.
An annular flange we projects from the lower side of the whorl I the said flange
overhanging the upper end of the tang m and serving to prevent the fibres of wool
or other material being spun from gathering around the base of the sleeve E and
impeding the free rotation of said sleeve on the spindle A.
The upper end of the tang m is provided with an annular groove in which a
ring 47 composed of felt or similar absorbent material is placed to catch and absorb
any surplus oil which may pass down between the spindle A and sleeve E.
It will be understood that the spindle A, is "dead" or stationary, and that the
sleeve, cap-plug and flyer are rotated thereon by a belt (not shown) on the whorl H
the hobbin or spool being disposed on the sleeve and raised and lowered in the usual
manner.
The oil for lubricating the bearing of the spindle A, in the socket t and also for
lubricating the contact surfaces between the sleeve and said spindle may be introduced
through the duct 45 without removing the sleeve, cap-plug or flyer, thereby rendering
it very convenient to lubricate the device and saving much time in the operation.
The sleeve being contiguous to the spindle proper on all sides thereof, the capillary
action is such that the oil passed through the auxillary duct b, will be held suspended
between the sleeve and the said spindle for a great length of time, thereby economizing
its use and rendering it unnecessary to lubricate the spindle as frequently as ordinary
spindles require lubricating, while the sleeve cap-plug and flyer being pivotally
supported on the pintle enable the bobbin and flyer to be driven at a much greater
speed than is practicable in spindles of this character as usually constructed.
The oil-duct 45 may be carried through the top of the plug D, if preferred instead
of through its side, whether the duct K and its auxillary ducts are employed or not
the duct 45 being shown in Figure 3 as passing through the top of the said, plug and
the duct K and auxillary ducts d, b omitted.
In Figure 2 the pintle fis represented as formed on the plug D, instead of on the
spindle A, and a step N, of metalline, graphite, babbett or similar material introduced
between the top of the spindle and the said plug, the step being secured to the spindle
by a pin v. The duct 45, also passes upward through the top of the said plug instead
of through its side, as in Figure 1. An oil-cup i, is also formed in the step N, for
receiving and holding a portion of the oil introduced through the oil-duct.
We however, deem the form and construction shown in Figure 1, preferable, as it
enables the oil to be introduced with greater convenience, while the duct K, and its
auxiliaries serve to distribute to better advantage in most instances.
We do not therefore confine ourselves to forming the pintle, on the spindle proper,
as it may be formed on the cap-plug D. Neither do we confine ourselves to having
the upper end of the duct 45, open through the side of the cap-plug D; nor to the
use of the duct K, and its auxiliary ducts; nor to employing both of the said
auxiliary ducts when the duct K, is used.
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 :-
First. The combination of the following instrumentalities to wit; a spindle, a sleeve
disposed on the said spindle and having a whorl or pulley secured thereto; a cap-plug
far the said classes bri

page_text: and pintle for pivoting the sleeve on the spindle; a duct in the cap-plug for intro-
ducing oil to the said pintle and socket; and a flyer mounted on the said cap-plug,
substantially as set forth.
Second. The spindle A, provided with the pintle; the sleeve E, provided with the
whorl H the cap-plug D, secured to the upper end of the said sleeve and provided
with the socket t, duct 45, and a screw-threaded portion for attaching the flyer ; and
the flyer J, combined and arranged to operate substantially as described.
Third. The spindle A having an oil-duct, as K, in its upper end, in combination
with a sleeve mounted on the said spindle and carrying a whorl and flyer, and with
a duct connecting with the duct in the spindle through which oil may be introduced
to the upper portion of the spindle without removing the said sleeve, substantially as
set forth.
Fourth. The spindle A, having the duct K, at its upper end provided with an
auxillary duct, as d, leading therefrom through the side of the spindle, in combination
with the sleeve E, carrying the whorl H, and flyer J, said sleeve being fitted to rotate
on the said spindle, and with a duct, as 45, communicating with the duct in the
spindle, substantially as described.
Fifth. The spindle A, having the duct K, at its upper end provided with an
auxillary duct leading therefrom as 6 through the side of the spindle, the said auxillary
duct being inclined upward to form a pocket, as », in combination with the sleeve Ĕ
carrying the whorl H, and flyer J, said sleeve being fitted to rotate on the said spindle,
and with a duct as 45, communicating with the duct in the spindle, substantially as

Sixth. The spindle A having a tang as m, provided with an annular grooves, in
combination with an absorbent material, as 47, disposed in the said groove, substantially
as and for the purpose described.
