WE, JONATHAN BOWDEN, of 290, Rochdale Road, Oldham, Carriers' Agent, and
JOHN WALKER, of 70, Swan Lane, Derby Street, Bolton, Machinist, both in the
County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements upon the machine for which Letters
Patent were granted to us, dated 14th April 1892, No. 7179.
In the first place instead of driving the second motion shaft described in the
Specification of the above Letters Patent directly from the driving shaft we now
divide the driving shaft in two lengths the first part actuating the gearing for
rotating the tin drum or the skewed gearing by a bevel wheel keyed fast thereon
and the second part of the said shaft being driven by suitable spur gearing and
an intermediate shaft at the required speed for actuating the rise and fall of the
disc beam. We put more than one pair of carrier wheels to this last named range
of gearing if required to give a greater length of yarn to one traverse of the disc
beam.
The drawing rollers are driven directly from the first shaft at a regular speed.
We now fix the thread wires or guides to boards carried by the roller stand beam
instead of fixing each wire guide to the disc-beam.
We also work the gearing for obtaining the rise and fall of the spindle rail from
a special lever working on the top of the cam which works the lever connected to
the disc beam and we connect this special lever above named by an adjustable rod
to the pawl of the ratchet wheel.
In front of the disc-beam we place on projecting arms a rail which is bored to
any required gauge, at points corresponding with the spindles and we fit this rail
with bolsters or collars on which the "discs or twisters revolve.
دو
These bolsters are bored through and a long collar or bolster fixed to the spindle
rail below passes through each of them and supports its spindle at the desired
height; and this long collar or bolster moves up and down without touching the
disc bolster.
This arrangement gives great steadiness to the spindles while revolving.
On the spindle rail we provide a small lever one end of which is lined or shod
with leather or similar material and presses on the spindle and on the other end a
small traverse movable or adjustable weight acts so as to give the pressure
necessary for making the yarn harder on the spindle, or on the tube or bobbin.

We, JONATHAN BOWDEN, of 290, Rochdale Road, Oldham, Carriers' Agent, and
JOHN WALKER, of 70, Swan Lane, Derby Street, Bolton, Machinist, both in the
County of Lancaster, 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 :-
This invention relates to improvements upon the machine for which Letters
Patent were granted to us, dated 14th April, 1892, No. 7,179, and the same will be
readily understood from the following description on reference to the accompanying
drawings.
On Sheet Fig. 1 is a front elevation and Fig. 2 a plan view of so much of a
spinning machine made according to the Specification of the above Letters Patent
as is necessary to illustrate our present invention.
On Sheet 2 Fig. 3 is a section through the line A-B on Fig. 1 and Fig. 4 a
similar view through C-D on the same fig.
Fig. 5 is a partial horizontal section through E-F on Fig. 3.
j
On Sheet 3, Fig. is a partial front elevation drawn to a larger scale. Fig. 7 is
a side view thereof in section, and Fig. 8 a detached plan of the brake hereafter
described.
Where possible the same letters are used on these drawings as on those of the
Specification of the aforesaid Letters Patent.
In the first place instead of driving the second motion shaft described in the
Specification of the above Letters Patent and marked 5 on the accompanying
drawings thereof directly from the driving shaft markeds thereon we now divide
the driving shaft in two lengths s s¹ which latter wo term the building shaft as it
controls the building of the cop (see Fig. 2 here to annexed) the first part actuating
the gearing 2, 2, 3, (Fig. 2) for rotating the tin drum i (or the skewed gearing) by
a bevel wheel y keyed fast thereon, and the second parts of the said shaft being
driven by suitable spur gearing t and an intermediate shaft t¹ at the required speed
for actuating the rise and fall of the disc beam d. We put more than one pair of
carrier wheels to this last named range of gearing t if required to give a greater
length of yarn to one traverse of the disc beam d.
The drawing rollers are driven directly by the bevel gear 22 and 8x and shaft 2
from the first shaft s at a regular speed (see Figs. 1 and 3).
We now fix the thread wires or guides 32 to boards ex carried by the roller stand
beam cinstead of fixing each wire guide to the disc-beam d as specified in the
Specification of our previous Patent.
We also work the gearing for obtaining the rise and fall of the double spindlo
rail n from a special lever n¹ (see Fig. 3) working on the top of the cam 10, which
works the lever 11 connected to the disc beam & and we connect this special
lever above named by an adjustable rod n² to the lever 24 which carries the
pawl 25 of the ratchet wheel 26.
In front of the disc-beam d we place on projecting arms a rail d¹ (see also
Sheet 3) which is bored to any required gauge, at points corresponding with the
spindles r and we fit this rail with bolsters 2 or collars (see Figs. 6 & 7) on
which the "discs or twisters revolve.
"
These bolsters & are bored through and a long collar or bolster n fixed to the
spindle rail below, passes through each of them and supports its spindler at the
desired height; and this long collar or bolster n moves up and down without
touching the disc bolster d².

page_text: This arrangement gives great steadiness to the spindles while revolving.
On the double spindle rail n we provide a small lever 1 (Sheet 3) one end of which
is lined or shod with leather or similar material at land presses on the spindle
and on the other end which is weighted at a small transverse movable or
adjustable weighted rod or wire acts as follows so as to give the pressure necessary
for making the yarn harder on the spindle », or on the tube or bobbin.
is
Beneath the weighted end of this lever is a long wire or light rod 13 carried by
arms pivotted at to a bar connecting the two rails n, one of the arms
provided with a finger or projection connected by cord or chain to a pulley x
carried by the rail d so that as the rail d drops and the yarn is being wound on the
Jarger diameter of the cop, the lever lowers the wire and allows the full amount
of the drag to be applied to the spindles r by the levers l, and as the rail & rises
the drag is taken from the spindles by the cord lifting the wire and the
weighted ends of the levers 7. The cord merely acts as a friction brake to prevent
the double pulley (x ** from over-running, its upper end being attached to the
rail d.
As the cop is being formed and the rail n descends the cord 6 will be unwound
from the pulley 1x but the weighted cord acting on the pulley /** sustains the
weight of the wire and its adjuncts.
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 :-
1. The improved means for driving the building shaft substantially as herein-
before described and illustrated.
2. The improved means for obtaining the rise and fall of the double spindle rail,
substantially as hereinbefore described.
3. The combination of rails d and d' carrying the bolsters d² on which the
twisters revolve substantially as hereinbefore described and illustrated by the
annexed drawings.
4. The combination of the bolsters d² with long collars * on the spindle rail for
supporting the spindle.
5. The combined improvements on our spinning machine arranged and operating
substantially as hereinbefore described.
