Machinist. "IMPROVEMENTS IN APPARATUS EMPLOYED IN THE SPINNING OF FIBROUS
MATERIALS, APPLICABLE ALSO TO DOUBLING MACHINES." [Partly a communica-
tion from abroad by Oscar Rerke, of Rheydt aforesaid.]
The Invention relates to the spindles and to the method of mounting the same and
to connected parts, and whilst being particularly applicable to ring throstles may
also be applied with advantage to mules and other spinning machinery and to
doubling machines.
The spindle is arranged to revolve in two bearings in a tubular bolster.
The lower foot step bearing may be formed in the metal of the bolster or in a
piece fixed in the bottom of the said bolster. The upper end of the bolster is by
preference bushed to form the upper bearing. The said bolster is secured by its
upper end to a rail.
A collar on the upper end of the bolster bears on the top of
the rail, and a nut on a screwed part of the bolster serves as a means for attachment,
but this may be varied. The top of the bolster projects to a comparatively small
extent above the top of the rail, the greater part of the length of the bolster
extending below the rail. A recess to receive oil is forined in the top of the
bolster. To the spindle is fixed a wharve or whorl, which is formed to extend over
and to cover the top of the bolster. It is preferred that this wharve shall be
as near as conveniently possible to the upper surface of the said rail, and also that
the line of pull of the band shall be about level with the top of the upper bearing.
The upper part of the said wharve is formed as a hollow cone to receive the bobbin,
or is otherwise formed to grip.or engage with it.

page_text: The bobbin is bored to fit the spindle at a part of its length a little above tho
centre or at any other suitable point.
As this bobbin need only to so much larger than the spindle as is necessary to
the obtainment of sufficient strength, a bobbin smaller in diameter may be used
than in cases wherein the bobbin has to be mounted on a sleeve fixed to the spindle,
and therefore more yarn may be wound upon the bobbin, or the spindles may be
spaced nearer together so as to obtain a greater number of spindles in a frame of
given size. The bobbins and the revolving parts are lighter, and therefore require
less driving power, and also the strain of the aforesaid sleeve upon the spindle,
arising from the pull of the band, is avoided. The arrangement is very suitable to
be used in cases wherein ordinary throstles have to be converted into ring throstles.
In such cases the fixed rail may be drilled to receive the said bolsters, and be fixed
at the required level and the lifting rail be drilled or bored to suit the ring spinning,
and be provided with the rings.

Machinist. "IMPROVEMENTS IN APPARATUS EMPLOYED IN THE SPINNING OF FIBROUS
MATERIALS, APPLICABLE ALSO TO DOUBLING MACHINES." Partly a communi-
cation from abroad by Oscar Rerke, of Rheydt aforesaid.
The Invention relates to the spindles and to the method of mounting the same
and to connected parts, and whilst being particularly applicable to ring throstles
may also be applied with advantage to mules and other spinning machinery and to
doubling machines.
The spindle is arranged to revolve in two bearings in a tubular bolster. The
lower. footstep bearing may be formed in the metal of the bolster or in a piece
screwed or fixed in the bottom of the said bolster. The upper end of the bolster is
by preference bushed to form the upper bearing. The said bolster is secured by its
upper end to a rail.
A collar on the upper end of the bolster bears on the top of
the rail, and a nut on a screwed part of the bolster serves as a means for attach-
ment, but this may be varied. The top of the bolster projects to a comparatively
small extent above the top of the rail, the greater part of the length of the bolster
extending below the rail. A recess to receive oil is formed in the top of the bolster.
To the spindle is fixed a whorl, which, is formed to extend over and to cover the
top of the bolster. The upper part of the said whorl is formed as or is provided
with a hollow cone to receive the bobbin, or is otherwise fitted to grip or engage
with it..
In order that my Invention may be fully understood I have attached hereunto a
Sheet of Drawings made about the full size, and marked with letters of reference,
to which Drawings I will now refer. Fig. 1 represents a spindle formed, mounted,
and fitted in accordance with my Invention; and Fig. 2 represents the same spindle
with the bearings and other parts in section. In the said Figs. a is the spindle;
bis the bolster; c is the whorl; and d'in Fig. 1 is the bobbin, represented partly
in section: The said bolster is formed with a collar b¹, which rests upon the rail
indicated by e. The bolster is secured in position in or upon the rail by means of
nuts, which engage with a screw thread formed upon the exterior of the bolster.
It will be seen that the greater portion of the length of the bolster extends below
the rail, a comparatively short length extending above the said rail. The said
bolster is bored throughout, the upper end being bored to receive a bush g of anti-
friction metal or of a suitable metal or alloy, or if preferred the said bush may be
dispensed with, and the upper end of the bolster he bored to act as a bearing for
the spindle. From the bush g downwards the bolster is bored a little larger than
the part bored to receive the said bush, and with the same tool or adjustment, so as
to be truly in axial line with such part; but if preferred the bolster may be bored
throughout to an uniform diameter of bore. The upper end of the bolster is cupped
or recessed to receive the lubricant. The footstep bearing is formed in a piece h,
which is formed to screw into the lower end of the bolster. The upper end of this
footstep piece is turned to accurately fit the bore of the bolster, and the bearing in
the said piece is drilled so as to be truly concentric with the turned exterior of the
said piece, so that the upper and lower bearings are caused to be truly in line as
near as may be. Between the spindle and the inner bore of the bolster is an
annular space, which is or may be filled with lubricant. By lifting out the spindle
and unscrewing the part h the bearings and lubricant space can be readily cleansed.
Upon the spindle at a point near to the top of the bolster is fixed the whorl c,
which is dished on the underside so that it can extend a little below the top of the
bolster. In the example the pull of the driving band would be very little below

page_text: the top of the bearing, and be very nearly in the centre of the entire length of the
spindle. Upon a collar formed on the said whorl is fixed a conically shaped brass
or metal cup i, into which the lower end of the bobbin fits. This cup may be
formed in one piece with the whorl if preferred. At a part of the ‘bobbin.it is
bored to.fit. the upper end of the spindle. As the bobbin need only be so much
larger than the spindle as is necessary to the obtainment of sufficient strength, a
bobbin smaller in diameter may be used than in cases wherein the bobbin has to
be mounted on a sleeve fixed to the spindle, and therefore more yarn may be wound
upon the bobbin, or the spindles may be spaced nearer together so as to obtain a
greater number of spindles in a frame of given size. The bobbin and the revolving
parts are lighter, and therefore require less driving power, and also the strain of
the aforesaid sleeve upon the spindle arising from the pull of the band is avoided.
As the motion is transmitted to the spindle at about the centre of its length, and as
the portion of the spindle below the top of the bolster is about equal in length to
the portion above such top, the spindle is well balanced so that there is less
vibration of the upper end of the spindle. I consider these indicated proportions
of the parts to be important as means for obtaining greater steadiness under high
velocities. A wire l'bent over, the whorl at its upper end prevents the spindle
from being lifted out of its place when the bobbin is doffed. The bent portion of
this wire can be turned out of the way when it is desirable to lift the spindle out
of its bearings. Any other suitable device may be used in lieu of the said wire.
The arrangement illustrated in the Drawings is particularly designed for use in
ring throstles. For other throstles or spinning machinery modifications in the form
of the bobbin and in the method of mounting it upon the spindle are made, or the
bobbin is dispensed with, as may be most suitable in each case. The arrangement
is very suitable to be used in cases wherein it is desirable to convert ordinary
throstles into ring throstles. In such cases the fixed rail may be drilled to receive
the improved bolsters and be fixed at the required level, and the lifting rail bé
drilled or bored to suit the ring spinning, and be provided with ordinary or
suitable rings.
Having now fully set forth and indicated the nature of the said Invention, and
the manner in which the same is carried into effect, I would have it to be under-
stood that I claim,-.
First. The spindle mounted to revolve in a bolster, and provided with a whorl
and with or without the bobbin and conical cup, all arranged, proportioned, and
acting substantially as and for the purpose set forth and indicated herein before and
in and by the accompanying Drawings.
And, Secondly. The combination of the bolster secured by its upper end to the
rail or framing, and provided with a removable footstep piece, the spindle having
about half of its length in the said bolster, and the whorl formed and fixed so that
the pull of the band is about level with or a little below the upper end' of the
top bearing in the bolster, substantially as: and for the purposes set forth and
indicated.
In witness whereof, I, the said Wilhelm Gustav Hugo Peltzer, have hereunto
set my hand and seal, this Fourteenth day of February, in the year of our
Lord One thousand eight hundred and eighty,
