Improvements in what are Commonly Termed Self Contained
Spindles Used for Spinning, Twisting, and Winding Fibrous
Materials.
We SAMUEL HERBERT BROOKS of the Union Iron Works, West Gorton, Man-
chester, in the County of Lancaster, Machine Maker, THOMAS GOODBEHERE,
Manager, and FREDERICK GEORGE GOODBEHERE, Cashier, of the same place do
hereby declare the nature of the said invention to be as follows:
Our invention relates to combinations of parts forming what are commonly termed
self contained Spindles, that is, to combinations in which the spindle, warf, holding
down hook or equivalent part, bolster and footstep, and the holder, are all connected
and combined parts the holder for which is inserted and secured in the rail in which
the self contained spindle is to be held or carried.
Self contained spindles are in use formed by a holder secured in the carrying rail
which holder forms an oil chamber and has within it a tube variously formed and
arranged more or less laterally or vertically or in both directions, such tube or part
forming the combined bolster and footstep bearings of the spindles.
It has also been proposed to arrange a tube forming an oil chamber having bolster
and footstep bearings fixed or formed within it, so that it can be held within another
tube forming the holder, which holder is secured in the rail and the said bolster and
footstep tube and oil chamber is arranged to be withdrawn from the holder leaving
the spindle in other respects undisturbed.
Our invention refers to combinations of both of the above described arrangements,
and consists in combining any of the known forms and constructions of flexible
movable or self adjustable combined bolster and footstep bearings, or modifications
thereof, arranged within a tube this tube forming an oil chamber and is placed within
and is carried by the tube of an holder secured to the rail.
The said tube or oil chamber having the self adjustable combined bolster and
footstep bearings within it, is or may be itself arranged by our invention to be more
or less flexible, movable or self adjustable in the tube holder, similar to the combined
bolster and footstep tube.

page_text: This said tube or oil chamber, is arranged to be readily withdrawn when desired
to be cleaned or have the oil renewed or for other purposes, from the holder, and is
secured therein or thereto by a cap attached by a bayonet joint fixing, or by a screw,
or any other suitable arrangement.
In some of our improved arrangements the combined self adjustable bolster and
footstep tube is held vertically by an helical spring or cushion of cork or other
suitable material, and it is in some cases held laterally by springs of steel or by
suitable elastic fibrous or other material.
The same or modifications of the same arrangements are or may also be applied
according to our invention to the withdrawable tube or oil chamber containing the
self adjustable combined bolster and footstep bearing in combination with its
holder.

Improvements in what are Commonly Termed Self Contained
Spindles Used for Spinning, Twisting, and Winding Fibrous
Materials.
We SAMUEL HERBERT BROOKS, of the Union Iron Works, West Gorton,
Manchester, in the County of Lancaster, Machine Maker, THOMAS GOODBEHERE,
Manager, and FREDERICK GEORGE GOODBEHERE, Cashier, of the same place, 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 combinations of parts forming what are commonly termed
self contained spindles, that is, to combinations in which the spindle, warf, holding
down hook or equivalent part, bolster and footstep, and the holder, are all connected
and combined parts the holder for which is inserted and secured in the rail in which
the self contained spindle is to be held or carried.
Self contained spindles are in use formed by a holder secured in the carrying rail
which holder forms an oil chamber and has within it a tube variously formed and
arranged more or less loose laterally or vertically or in both directions, such tube or
part forming the combined bolster and footstep bearings of the spindles.
It has also been proposed to arrange a tube forming an oil chamber having bolster
and footstep bearings fixed or formed within it, so that it can be held within another
tube forming the holder, which holder is secured in the rail and the said bolster and
footstep tube and oil chamber is arranged to be withdrawn from the holder, leaving
the spindle in other respects undisturbed.
Our invention refers to combinations of both of the above described arrangements
and consists in combining any of the known forms and constructions of flexible,
movable or self adjustable combined bolster and footstep bearings, or inodifications
thereof, arranged within a tube, this tube forming an oil chamber and is placed
within and is carried by the tube of an holder secured to the rail.
The said tube or oil chamber having the self adjustable combined bolster and
footstep bearings within it, is or may be itself arranged by our invention to be more
or less flexible, movable or self adjustable in the tube holder, similar to the combined
bolster and footstep tube.
This said tube or oil chamber is arranged to be readily withdrawn, when desired,
to be cleaned or have the oil renewed or for other purposes, from the holder, and is
secured therein or thereto by a cap attached by a bayonet joint fixing, or by a screw,
or any other suitable arrangement.
In some of our improved arrangements the combined self adjustable bolster and
footstep tube is held vertically by an helical spring or cushion of cork or other
suitable material, and it is in some cases held laterally by springs of steel or by
suitable elastic fibrous or other material.
The same or modifications of the same arrangements are or may also be applied

page_text: .
according to our invention to the withdrawable tube or oil chamber containing
the self adjustable combined bolster and footstep bearing in combination with its
holder.
Figs. 1 to 7 inclusive are clevations of various modifications of self contained
spindles, all the parts in each figure except the spindle being shown in section.
Figs. 8 to 13 are outside elevations of those parts detached which form a
modification of self contained spindle when put together the same or similar to that
represented by fig. 5.
Fig. 14 is a sectional elevation of the lower end of our self contained spindles
showing a modification different from that supposed to be used in the other
modifications for securing the exterior tubes in the holder.
In each modification figs. 1 to 7 inclusive a, is the holder, an outside elevation of
which is shown by fig. 11, this holder is secured in the spindle rail by the screw
nut a', and washer a², is the spindle used in each modification.
They are of various sizes and shapes, as shown, and are all cone formed at the
footstep end, except in the modification shown in fig. 3 which is coned but is flat at
the lower end.
C,
is the warf which is sleeved and is made of various forms, as shown, secured to
the spindle b. d is the exterior tube in each modification which can be withdrawn
from the holder a leaving the spindle resting by its warf on the top of the holder.
This tube d is held up within the holder a in each modification and is attached to it
by a cap e, an outside elevation of which is shown by fig. 13.
There is a
pin a³ in the side of the holder a and there is a bayonet fixing slot e¹ cut
in the side of the cap e, see fig. 13, by which it is secured to the holder a by pushing
it upwards and then turning it slightly round.
In each modification there is a hole for a pin x to pass through the solid part at
the lower end of the outer tube d, this pin coming below the flange of the cap e, so
that when the latter is released from the holder a, and the outer tube d is withdrawn
the cape and tube d will be connected.
In each modification there is also an helical spring f (an outside elevation of which
is shown by fig. 12) the lower end of which spring rests upon the inner end or flange
of the cap e, and the upper end of the spring comes against the end of the outer
tube d or a shoulder formed upon it.
Fig. 14 shows a modification where the cap e is made so as to screw upon and over
the screwed lower end of the holder a.
In the modification shown by fig. 1, the outer withdrawable tube d is formed in
two parts, the upper part d' screwing into the lower part d.
This arrangement admits of the inner tube g having within it the bearings for the
spindle, being formed with an enlarged part or shoulder g' which is forced upwards
against the shoulder formed by screwing in the upper part d' of the outer tube into
the lower part d.
There is a shoulder g' formed upon the exterior of the lower part of the inner
tube g which is reduced in diameter to enter a hole formed at the bottom of the outer
tube d, and one end of a helical spring rests against a shoulder at the bottom of
the outer tube d and acts upwards against the shoulder g² on the inner tube g.
The spring in fig. 1 acts upon a collar d' formed on the lower part of the
outer tube d.
This arrangement of the two helical springs allows of a slight vertical movement
both in the inner tube g and outer tube d.
There are spaces as shown between the exterior of the inner tube g and interior
of the outer tube d for oil, and there are or may be longitudinal grooves on the
exterior of the inner tube g, so that oil overflowing at the upper end of the inner
tube 9 may descend these said grooves on its exterior and pass through holes g³ to
the rubbing surfaces.
Fig. 2. In this modification the lower end of the outer tube d, is made with a
projection d³ upwards, there being an annular space between this upward projection d³
and the inside of the outer tube d.

page_text: The lower end of the inner tube g is made with a hollow or tubular projection gʻ to
pass over the upward projection d³ in the outer tube d and upon the upper end of the
upward projection d³ and between it and the inner tube g, within the tubular extension
thereof g there is a small piece of cork or other suitable clastic material g*.
Fig. 3. In this modification the upper part of the withdrawable outer tube d
contains an inner tube y which has a footstep bearing at its lower end and a thin bush
or shell bearing within the inner tube g for the bolster bearing.
Fig. 4. In this modification the outer tube d is short and it has a flange d' at its
lower end that comes against a shoulder within the holder a, and it is held up by the
helical spring resting upon the cape at one end, and against the lower end of the
outer tube d at the other end.
The middle part of the inner tube g has a collar g' formed upon it which rests upon
the upper end of the outer tube d.
..
Within the outer tube d is the lower part of the inner tube g which is formed with
a shoulder for a washer g' (with an open gap in one side) at the lower end of the
inner tube g.
The lower end of a spring h rests upon the washer 9' and the upper end of this
spring comes against a shoulder on the inner tube g, as shown, thus the inner tube g
is drawn downwards by the spring h, and the outer tube d is pushed upwards by the
other spring thus giving elasticity in both directions.
Within the upper part of the inner tube ga tube or bush i is inserted as a collar or
bolster bearing for the spindle b, there being space on the exterior of this tube or
bush i for oil, which can also descend to the footstep bearing within the inner tube
g.
Fig. 5. In this modification the outer tube d, has a collar d² at its lower end see
fig. 10 which is forced up by the spring against a shoulder formed within the
holder a.
The outer tube d has the upper part of its bore enlarged to receive the enlarged
part of the exterior of the upper part of the inner tube 9 (see fig. 9) and the shoulder
formed at the lower end of the enlarged part rests upon the shoulder formed within
the outer tube d.
Fig. 6. In this modification the outer tube d extends upwards to the upper part of
the hollow sleeve of the warf and there is a projection c¹ downwards from the warf
entering the upper end of the outer tube d, but not touching it.
The lower part of the inner tube g, is reduced on its exterior to form a shoulder
which rests upon one formed within the outer tube d, and the exterior of the upper
part of the interior tube g is reduced to give space for bent springs j acting between
the exterior of the inner tube g and the interior of the outer tube d.
Fig. 7. In this modification the outer tube d has within it an inner tube 9₁ the
lower end of which rests upon the lower end of the bore of the outer tube d.
The outer tube d goes nearly to the upper end of the hollow sleeve of the warf, and
the upper end of the inner tube does not extend so high, there being a small ring k.
round the spindle b to throw any oil that ascends above the upper end of the inner
tube g against the interior of the outer tube d where it again descends on the exterior
of the inner tube g to the footstep and bolster bearing.
The inner tubes g in each modification are or may be made with longitudinal
grooves g on their exteriors for lubricant to pass down between their exteriors and
the interior of the outer tube d, and there are or may be holes g³ through the shell
of the inner tube g to admit oil from the exterior of the inner tube g to the bolster
and footstep rubbing surfaces, and these grooves and holes for oil are or may be made
as illustrated by fig. 9.
In respect of the inner tubes 9 and outer tubes d, herein shown and described, they
are the same or similar to well known arrangements of bearings for self contained
spindles, but the outer tubes d are different from the well known arrangements above
referred to in their combination with the cap e, or its equivalent and the holder a.
Any of the well known arrangements for preventing the warfs from lifting may be
used with the modifications of self contained spindles described.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is,―
1. The combination and arrangement of the outer tubes d and the inner tubes
having bolster and footstep bearings for the spindles with the holder a, secured in the
spindle rail so that the outer tubes d can be readily withdrawn, along with the parts
contained in it from the spindle, leaving it resting by its warf upon the upper end of
the holder a, and readily replaced, substantially as hereinbefore described and illustrated
by the drawing.
2. The several combinations of parts forming what are termed self contained
spindles, substantially as hereinbefore described and illustrated by figs. 1, 2, 3, 4, 5, 6
and 7.
