Improvements in or applicable to Roving and Slubbing and other
Frames or Machines for Twisting and Winding or Preparing
Fibrous Materials.
1, WILLIAM TATHAM, of Vulcan Works, Rochdale, in the County of Lancaster,
Machine Maker, do hereby declare the nature of the said invention, to be as
follows:-
My invention relates to the spindle bearings of roving and slubbing frames and
similar machines for twisting and winding fibrous materials, and its object is
to arrange the spindles and their bearings in a simple manner, whereby increased
steadiness at high speeds is obtained by giving lateral support to the spindle, thus
preventing excessive vibration at high velocities and also whereby facilities are
obtained for cleaning, inspection and lubrication, while friction will be reduced as
the spindles will be free to accomodate themselves to any slight want of truth in
construction.
My invention is readily applied at little expense to existing roving and slubbing
frames.
In existing frames my invention consists (where this is required) in enlarging the
holes in the holders on the bobbin rails for the ordinary collars (which are dispensed
with) and in passing upon the spindle a long tube which fits and forms a bearing
for the spindle in which long tube the spindle rotates.
The lower end of this long tube extends to and may rest upon the top of
the wheel for driving the spindle, fast upon the lower end of the spindle, or upon
any other suitable and convenient support.
The upper end of this long tube passes into the spool upon which the fibrous
material is to be wound, and extends near to its upper end when the spool or bobbin
is in its lowest position.
The long tube is perfectly free in the holder in the bobbin rail, and this holder
slides up and down the long tube, which is prevented from rotating with the
spindle by having flat sides formed upon its lower end which engage with flats
formed or arranged on the sides of the holes through which the spindles pass in the
board that covers the wheels driving the spindles, or the said long tubes may
be held from rotating by any other convenient means.
Arranged as described the long tubes can be readily withdrawn for oiling,
cleaning, inspection or other purposes, and they leave the spindle in perfect
freedom, but considerably strengthen it, and thus prevent vibration at high speeds.
A modification of my invention consists in a long tube for each spindle which
extends upwards into the spool or bobbin to nearly its upper end or only into the
bobbin wheel and descends downwards through the collar bearing holder, to
or nearly to the top of the wheel upon the spindle when the bobbin rail is in
its lowest position.
This modification of long tube has a collar or other projection upon it, above the
holder for the collar bearing, so that in this case it rises and falls with the bobbin
rail, and is always at the same distance above it.
The long tube is perfectly free in the holder for the ordinary collar bearing
(which is dispensed with) but is held from rotating with the spindle by a projection
engaging with the holder for the collar bearing or by other suitable means.
It will be seen as before stated that the long tube in each case takes the place of
the ordinary collar bearings whether long or short, and that it is free in the
ordinary collar bearing holder upon the bobbin rail.
My improvements are applicable to frames, having ordinary, collar bearings r

page_text: to those having swivel bearings (though it dispenses with the necessity for swivel
bearings) or to my patented split holder for collar bearings, or to other forms of
bearing or bearing holders for spindles.

COMPLETE SPECIFICATION.
Improvements in or applicable to Roving and Slubbing and other
Frames or Machines for Twisting and Winding or Preparing
Fibrous Materials.
I, WILLIAM TATHAM, of Vulcan Works, Rochdale, in the County of Lancaster,
Machine Maker, 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 to the spindle bearings of roving and slubbing frames and
similar machines for twisting and winding fibrous materials, and its object is to
arrange the spindles and their bearings in a simple manner, whereby increased
steadiness at high speeds is obtained, by giving lateral support to the spindle, thus
preventing excessive vibration at high velocities and also whereby facilities_arc
obtained for cleaning, inspection and lubrication, while friction will be reduced as
the spindles will be free to accomodate themselves to any slight want of truth in
construction.
My invention is readily applied at little expense to existing roving and slubbing
frames.
In existing frames my invention consists (where this is required) in enlarging the
holes in the holders on the bobbin rails for the ordinary collars (which are dispensed
with) and in passing upon the spindle, a long tube which fits and forms a bearing
for the spindle in which long tube the spindle rotates. The lower end of this long
tube extends to and may rest upon the top of the wheel for driving the spindle, fast
upon the lower end of the spindle or upon any other suitable and convenient
support.
The upper end of this long tube passes into the spool upon which the fibrous
inaterial is to be wound, and extends near to its upper end when the spool or bobbin
is in its lowest position. The long tube is perfectly free in the holder in the
bobbin rail, and this holder slides up and down the long tube, which is prevented
from rotating with the spindle by having flat sides formed upon its lower end which
engage with flats formed or arranged on the sides of the holes through which the
spindles pass in the board that covers the wheels driving the spindles or the said
long tubes may be held from rotating by any other convenient means.
Arranged as described the long tubes can be readily withdrawn for oiling,
cleaning, inspection or other purposes, and they leave the spindle in perfect
freedom, but considerably strengthen it, and thus prevent vibration at high
speeds.
A modification of my invention consists in a long tube for each spindle which
extends upwards into the spool or bobbin to nearly its upper end or only into the
bobbin wheel and descends downwards through the collar bearing holder, to or
nearly to the top of the wheel upon the spindle when the bobbin rail is in its
lowest position.
This modification of long tube has a collar or other projection upon it, above the
holder for the collar bearing, so that in this case it rises and falls with the bobbin
rail and is always at the same distance above it.
The long tube is perfectly free in the holder for the ordinary collar bearing
(which is dispensed with) but is held from rotating with the spindle by a projection
engaging with the holder for the collar bearing or by other suitable means.

page_text: It will be seen as before stated that the long tube in each case takes the place of
the ordinary collar bearings whether long or short, and that it is free in the
ordinary collar bearing holder upon the bobbin rail.
My improvements are applicable to frames, having ordinary collar bearings or to
those having swivel bearings (though it dispenses with the necessity for swivel
bearings) or to my patented split holder for collar bearings, No. 4935 of 1883, or to
other forms of bearing or bearing holders for spindles.
Fig. 1 is an elevation in section illustrating a spindle for slubbing, intermediate
and roving frames according to my invention. The lower part only of the presser
flyer is shown (which is an ordinary presser flyer) to bring it within the sheet.
a, is the spindle of ordinary form and construction, the lower end being in
an ordinary footstep bearing and having a skew bevel wheel b, upon it to gear with
one on the horizontal driving shaft b', in the ordinary manner.
c, is a part of the branch for the holder c, similar to that for the ordinary long
or short collar of slubbing and like frames.
Upon the spindle a, there is a long metal tube d, which fits so as to slide freely
in the hole in the holder c', which slides up and down the long tube d, according
to one modification of my invention. The spindle a, can rotate freely in the long
tube d, which is prevented from revolving with the spindle by forming one flat or
two flats on opposite sides of it to fit a hole with corresponding flats in the board e,
covering the gearing that drives the spindles. The top side of the board has or
may have strips of metal e', secured to it to come against the flats, on the lower
end of the long tube d, in which case the hole in the board e, may be circular and
without flat sides, the metal strips.e', forming the flat edges to come against the
flat sides d'.
Another mode of preventing the long tube d, from rotating with the spindle a, is
by forming a groove in its lengthway and arranging a pin in the holder c³, to enter
the groove in the long tube d, the groove in which being of such length and in such
position as will allow the pin in the holder c¹, to travel up and down in the groove
with the bobbin rail.
The upper end of the long tube d, extends into and within about half an inch of
the upper end of the inside bore of the bobbin or spoolf, when in its lowest position,
as shown in Fig. 1, the presser g, of the flyer being shown in its position when the
bobbin or spool is in its lowest position.
The exterior of the long tube d, is clear of the inside bore of the bobbin or
spool which rests upon and is rotated by the skew bobbin wheel, the lower
edge of which rests upon and is supported by the upper surface of the holder c¹.
The upper part of the bobbin wheel enters the bore of the barrel of the bobbin or
spool at its lower end to keep it central and from touching the long tube d.
i, is the shaft for driving the bobbin wheels; j, is part of the board covering the
bobbin gearing.
Fig. 1 will also illustrate the second modification of my invention in which
the long tube d, slides up and down the spindle a, with the bobbin rail.
The bobbin, and holder c', are shown in their lowest positions in Fig. 1—then
by forming a collar d², (represented by dotted line) fast upon the long tube d, the
lower surface of this collar resting upon the upper face of the holder c', the lower
part of the boss of the bobbin wheel h, resting and rotating upon the upper face of
the collar (P.
There is or may be a notch in the collar into which a pin c³, can enter, which pin
is secured in the upper face of the holder c, and will prevent the tube d, from
rotating.
By removing the flyer, bobbin and bobbin wheel from the spindle a, the tube d,
can be readily withdrawn and replaced.
The lower end of the tube d, in this modification does not require the flats d',
and is just clear of the upper side of the spindle wheel b, when in its lowest position
upon the spindle.
I prefer to arrange the tube d, as above described in both modifications, that is,

page_text: so as not to rotate, but if desired it may be left free to rotate or not, as the
frictional action of the spindle a, on its inside and of the bobbin wheel h, outside
the tube d, tends to rotate it while its friction in the holder c', to some extent
counteracts rotation.
Having now particularly described and ascertained the nature of my said:
invention, and in what manner the same is to be performed, I declare that what
I claim is.
1. In slubbing, intermediate, roving and like frames, the combination and
arrangement of a long tube (d) with the spindle, such long tube (d) being free in
the holder (¹) and which tube does not rise and fall with the bobbin rail or rotate
with the spindle, substantially as and for the purpose hereinbefore described and
illustrated by the drawings.
2. In slubbing, intermediate, roving and like frames the combination of a long
tube (d) with the spindle, which is free in the bobbin rail holder (c') which does
not rotate with the spindle, but slides up and down the spindle with the bobbin rail,
substantially as hereinbefore described and illustrated by the drawings.
3. The combinations mentioned in Claims 1 and 2 when the tube d, is at liberty
to rotate, substantially as herein before described.
