Our invention relates to improvements in machinery for spinning and the
objects of the first part of our improvements are to prevent the spindles from
being lifted during the operation of doffing and to provide a simple method for
releasing the spindles when it is desired to remove them for cleaning or other
purposes.
In performing the first part of our Invention we use wires for acting on the
spindle wharves. Each of these wires is spring tempered and doubled at its
upper end which is bent at an angle so as to catch the spindle wharve and hold it
during the operation of doffing: the lower portion of each of these wires passes
through a vertical opening or slot smaller in breadth at the top than the bottom,
formed in the edge of the boss of the spindle bush and the extreme ends are bent
and lie in a groove or alot made in the lower side of the spindle bush which enters
the vertical slot or opening and is at right angles to it. The lower ends of each wire
thus lie between the spindle bush and the upper side of the spindle rail and a strong
and simple hinge is thus formed. Each wire is turned down on its hinge in order
to release the spindle and may be pushed up and allowed to spring back into
position after the spindle has been replaced.
In another arrangement for effecting this object we secure the wires for acting
on the spindle wharves as follows:-A stud or pin with an enlarged head is

page_text: screwed or fixed into the bolster flange and the hooked pin is hinged to the head of
the stud by means of a button-hook or snap joint. A stud and wire hook are
required for each spindle.
The second part of our improvements relates to the bearings and lubrication of
those spindles which bave their footstep and upper bearing in one tube and the
object is to obtain a constant lubrication with a removable oil reservoir combined
with an elastic or yielding bearing for the spindle.
In performing this part of our Invention we employ a bolster which may be
secured to the bolster rail by a nut in the usual manner: the bolster has a hole
through it into which the spindle tube enters and rests and projects through the
bottom of the bolster: the tube is bored and finished to form the footstep and
bearing for the spindle: the tube is enlarged at the top to rest on the bolster and
has narrow grooves turned on its periphery: one or more near the top and also at
the bottom a short distance above the spindle footstep: in these grooves, springs
preferably of flat steel wire, are coiled and bear against the inner face of the
bolster thus ensuring an elastic or yielding bearing for the spindle: in place of
spiral springs we can use a split ring or rings of metal which are put into the
grooves and have several curved pieces of flat spring wire attached to them which
bear against the bolster: the oil passes through a hole in the tube above the footstep
and thence is carried by the rifling or grooves on the spindle to the top of the tube
and into a recess formed in the upper part and from which it descends on the
outside of the tube to the oil cup or reservoir.
The spindle wharve may be formed to cover the upper part of the bolster and
tube.
In another modification the bolster is made in the manner last described with a
hole through it, the lower portion of the hole being larger than the upper: the
tube is enlarged at the top so as to rest on the bolster: a spiral spring is coiled
round the tube: one end of this spring bears on the under side of the enlarged
top and the other end rests on a collar in the bolster near the bottom : this
spring does not fill the space between the tube and bolster except for some
distance at the top but it may be confined at the bottom also: the intervening
space where the spring is unconfined insures an elastic or yielding bearing for the
spindle.
In another modification the hole through the bolster is contracted in diameter
for some distance near the centre: the tube has an enlarged head to rest on the
bolster and the outer surface is surrounded with a spiral spring: a portion of the
surface of the tube is turned "barrel shaped" so that the spiral spring fills the
space between this portion of the tube and the contracted portion of the hole
through the bolster and thus allows the spindle to vibrate slightly.
In another modification the hole in the bolster is enlarged for some distance
near the centre: the tube has an enlarged head which rests on the bolster: the
lower outer portion of the tube is reduced in diameter from the bottom upward
extending into the enlarged recess in the bolster previously described: the springs
may be formed of flat strips of steel wire bent over at the top and supported in an
annular groove at the top of the bolster: these strips extend to the bottom of the
bolster and are confined between the tube and the bolster for some, distance near
the top while near the bottom where the tube is reduced in size they bear only
against the inner sides of the bolster and this construction allows the spindle
freedom of movement.
In another modification the tube projects upward considerably beyond the bolster
and it is formed with a projection which rests on the bolster at a point above the
bolster rail: the tube from this point downward to near the bottom of the bolster
is surrounded by a spiral spring: a portion of the interior of the bolster is recessed
and at this point the tube is of larger diameter than it is below and for a short
space above the spiral spring for a certain length near the middle bears only on
the enlarged part of the tube and at each end. it bears only on the inside portion of
the bolster this allows the spindle to vibrate slightly.

page_text: The upper portion of the tube is covered by part of the wharve and the oil
returns to the reservoir through a space between the tube and wharve and oil holes
formed in the projection and in the bolster.
In all the above cases the tube projects through and below the bolster.
In another modification the bolster projects to a considerable distance below the
bolster rail: the tube has an enlarged head which rests on the top of the bolster.
The bolster is made with a large chamber or recess extending the greater part
of its length: this chamber is contracted near the bottom where a spiral spring is
secured the tube rests in and is surrounded for a short distance by this spring;
the upper part of the tube is formed " barrel shaped" and 'the largest diameter
rests against the inner portion of the bolster.
:
The outside of the bolster below the nut is reduced in diameter and is covered
by the oil reservoir: in this case the bolster extends below the bottom of
the tube.
In all these different arrangements for carrying our Invention into effect the oil,
cup or reservoir is supported by the bolster or nut and the cup surrounds the
projecting end of the tube which has an oil hole drilled through it a little above
the footstep: the oil cup is removed to fill it with oil which should cover the oil
hole in the tube: the revolving spindle which may be rifled or not causes the oil,
to flow up the tube which is recessed at the top and is provided with an oil hole,
to conduct the oil back to the outside of the tube from which it returns to the
cup or reservoir.
The oil cup or reservoir is connected to the bottom of the bolster by a bayonet
joint made as follows:-The bolster has a short vertical groove terminating in a
hook form, cut on its surface and the oil cup has a small pin projecting slightly
into its interior which is readily slipped into the groove and moved slightly
sideways to secure the cup.-In the above case the bolster projects through.
the nut.
Another mode of holding the oil cup is to finish the lower end of the bolster and
the nut flush or nearly so with one another and to cut a vertical groove or grooves
in the nut with recesses into which a pin in the oil cup as above described may,
rest to hold the cup.
We prefer to make the spindle wharve either with a lip or flange or hollow so
as to cover the upper part of the bolster and prevent the escape of oil.

page_text: the nut flush or nearly so with one another and to cut a vertical groove or grooves
in the nut with recesses into which a pin in the oil cup as above described may
rest to hold the cup.
t We prefer to make the spindle wharve either with a lip or flange or hollow so as
to cover the upper part of the bolster and prevent the escape of oil.
And in order that our Invention may be fully understood and readily carried
into effect we will proceed to describe the accompanying two Sheets of Drawings
reference being had to the figures and letters marked thereon.
Figures 1 to 7 are views of spindles to which the first part of our improvements
is applied to prevent the spindles from being lifted during the operation of doffing
and by which we are. readily enabled to release and remove them when desired
and Figs. 8 to 19 are views of spindles having their footstep and upper bearing in
one tube, to which the second part of our improvements is applied so as to obtain a
constant lubrication with a removable oil reservoir combined with an elastic or
yielding bearing for the spindle.
In Figs. 1 to 3.-a. is the wire for acting on the spindle wharve b fixed to the
spindle b this wire a may be spring tempered and doubled at its upper end a'
which is bent at an angle so as to catch the spindle wharve b and hold it during
the operation of doffing: the lower portions of the wire a pass through a vertical
opening or slot c¹ smaller in breadth at the top than the bottom, formed in the
edge of the boss of the spindle bush or bolster c and the extreme ends a³ of the
wire are bent and lie in a groove or slot c' made in the lower side of the spindle
bush c which enters the vertical slot c¹ and is at right angles to it. The lower
ends a³ of the wire a thus lie between the spindle bush c and the upper side of the
spindle rail d and a strong and simple hinge is thus formed. The wire a is
turned down on its hinge a³ in order to release the spindle b² and may be
pushed up and allowed to spring back into position after the spindle 6' has been
replaced.
In Figs. 4 and 5 the collar or flange of the bolster c is shown grooved across
next to the spindle rail d so that the ends a² of the wire a rest in the slot c³ and
on the rail d: at the back of the collar is a vertical taper slot c' so that when the
wire a is pressed back the spindle b¹ can be taken out and as soon as the wire
is let go it springs back into its place through the taper slot c¹: the wire is
angled downward at a¹ in order that the spindle 61 may be replaced without
touching the wire a with the hands as the wharve b springs it back out of
the way.
Figs. 6 and 7 show another arrangement for effecting the same object in which
we secure the wire a in a different manner. A stud or pin e with an enlarged
head is screwed into or secured to the collar or flange of the bolster c and the
wire in this instance used singly not doubled, but bent or hooked at a¹ as previously
described, is hinged to the head of the stud e by means of a button hook or snap
joint e!
In Figs. 8, 9 and 10 a is the bolster secured to the bolster rail b by the nut c
in the usual manner: the bolster a has a hole a¹ bored through it into which the
spindle tube d enters and rests and projects through the bottom of the bolster :
the tube d is bored and finished to form the footstep and bearing for the spindle e:
the tube d is enlarged at the top to rest on the bolster a and has narrow grooves d¹
turned on its periphery in this instance one groove d¹ near the top of the tube
and another near the bottom at a short distance above the spindle footstep: in
these grooves d' springs fin this instance formed of flat steel wire, are coiled and
bear against the inner face of the bolster a (see Fig. 10) thus insuring an elastic
or yielding bearing for the spindle e: in place of spiral springs f, a split ring or rings
of metal may be used which are put into the grooves and have several curved
pieces of flat spring wire f' attached to them which bear against the bolster a (see
Fig 9). The oil cup, or reservoir g is formed and connected to the bolster a in the
manner hereinafter described: oil passes through a hole in the tube d above
the footstep and thence is carried by the rifling or grooves el on the spindle e to

page_text: the top of the tube d and into a recess formed in the upper part and from
which it descends on the outside of the tube d to the oil cup, or reservoir g:
The spindle wharve h is shown formed so as to cover the upper part of the bolster a
and tube d.
Fig. 11 represents a modification of our Invention in which the bolster a is
made in the manner described with a hole a¹ through it; the lower portion of the
bole being larger than the upper: the tube d is enlarged at the top so as to rest
on the bolster a: a spiral spring fis coiled round the tube: one end of the spring f
bears on the under side of the enlarged top and the other end rests on a collar a
in the bolster a near the bottom: the spring ƒ does not fill the space between
the tube d and bolster a except for some distance near the upper end of the
hole a but it might be confined at the bottom also: the intervening space
where the spring f is unconfined insures an elastic or yielding bearing for the
spindle.
Fig. 12 represents another modification of our Invention in which the hole a¹
through the bolster a is contracted in diameter for some distance near the centre:
the tube & has an enlarged head which rests on the bolster a and the outer surface
of the tube is surrounded with a spiral spring f: a portion of the surface of the
tube d is turned 64
barrel shaped" so that the spiral spring f fills the space between
this portion of the tube d and the contracted portion of the hole a¹ and thus allows
the spindle e to vibrate slightly.
Figs. 13 and 14 represent another modification of our Invention in which the
hole a' through the bolster a is enlarged for some distance near the centre: the
tube d has an enlarged head which rests on the bolster a: the lower outer portion
of the tube d is reduced in diameter from the bottom upward extending into the
enlarged recess in the bolster just described: the springs may be formed of flat
strips of steel wire ƒ (see Fig. 14) bent over at the top and supported in an annular
groove a' at the top of the bolster a: these strips f extend to the bottom of the
bolster a and are confined between it and the tube d for some distance near the
top while near the bottom where the tube d is reduced in size they bear only
against the inner sides of the bolster a and this construction allows the spindle e a
certain freedom of movement.
:
Fig. 15 represents another modification in which the tube d projects upward
considerably beyond the bolster a and it is formed with a projection d' which
rests on the bolster at a point above the bolster rail b: the tube d from this point
downward to near the bottom of the bolster a is surrounded by a spiral spring f:
a portion of the interior of the bolster is recessed at a³ and at this point the tube d
is of larger diameter than it is below and for a short space above: the spiral
spring for a certain length near the middle bears only on this enlarged part of
the tube d and at each end it bears only on the inside portion of the bolster this
allows the spindle e to vibrate slightly. The upper portion of the tube d is
covered by part of the wharve h and the oil returns to the reservoir g through a
space between the tube d and the wharve h and through the oil holes d³ formed
in the projection d' and similar oil holes at in the bolster a
f
In all the above described arrangements the tube d projects through and below
the bolster a.
Fig. 16 represents another modification of our Invention in which the bolster a
projects to a considerable distance beyond the bolster rail b. the tube d has an
enlarged head which rests on the top of the bolster a: the bolster a is made with
a large recess or chamber a³ extending the greater part of its length: this
chamber a³ is contracted near the bottom where a spiral spring fis secured: the
tube & rests in and is surrounded for a short distance by this spring f; the upper
part of the tube d is made "barrel shaped" and the largest diameter rests against
the inner portion of the bolster a. The outside of the bolster a below the nut c is
reduced in diameter and is covered by the oil reservoir g: in this case the bolster
extends below the bottom of the tube d.
Figs. 17, 18 and 19 represent another modification of our Invention in which

page_text: we dispense with the steel springs fand use instead india-rubber springs : the
india-rubber i is secured between the bolster a and the tube d see Fig. 19 and is
grooved spirally to insure equal pressure all over the cushion and thus form an
elastic bearing.
In all these different arrangements for carrying the second part of our Invention
into effect the oil cup or reservoir g is supported by the bolster a or nut c and the
oil cup g surrounds the projecting end of the tube d which has an oil hole d'
drilled through it a little above the footstep: the cup is removed to fill it with
oil which should cover the hole d³: the revolving spindle e which may be rifled
at e¹ or not, causes the oil to flow up the tube d which is recessed at the top at d³
and is provided with a hole to conduct the oil back to the outside of the tube d
from which it returns to the cup or reservoir g.
In Figs. 8, 13 and 16 the oil cup or reservoir g is shown connected to the
bottom of the bolster by a bayonet joint made as follows:-The bolster a has a
short vertical groove a* (see Fig. 8) terminating in a hook form, cut on its surface
and the oil cup g has a small pin g' projecting slightly into its interior: to secure
the cup g to the bolster a the pin g is slipped into the vertical groove a pushed
upward and then turned slightly sideways into the "hook" or recess. In these
arrangements the bolster a projects through the nut c.
In Figs. 11, 12, 15 and 17 another mode of holding the oil cup g is shown. In
these views the lower end of the bolster a and the nut c are finished flush or
nearly so with one another and a vertical groove c¹ with a recess is cut in the
nut c into which the pin gl as above described may rest to hold the oil cup g.
We prefer to make the spindle wharve h either with a lip or flange or hollow
so as to cover the upper part of the bolster a and prevent the escape of oil.
Having stated the nature of our Invention and described the manner of
performing the same
We declare that we claim
1. The improvements in machinery for spinning, substantially as herein shown
and described.
