Improvements in Spinning, Twisting, and Winding Frames for
Fibrous Materials, and in the Regulating the Tension of Spindle
Bands for same.
We, THOMAS ALEXANDER Born and J. & T. BOYD, LIMITED, both of Shettleston
Iron Works, Shettleston, Lanarkshire, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to improvements in spinning, twisting and winding
frames for fibrous materials and in the regulating the tension of spindle bands
for same.
The first part of our invention relates to means of regulating the tension of
spindle bands and of stopping groups of spindles by slackening the bands and
braking the spindles. We shall first describe one arrangement of this part of
our invention, applicable to cap frames in which the wharves are moved up and
down by the lifting rail, thus altering the distance from the wharve to the cylin-
der and also the tension of the bands. In doing so we employ a central driving
cylinder passing throughout the length of the frame. In front of the cylinder
and parallel with it we suspend a spindle rail fixed to the lower end of swinging
arms centred on the line passing through the thread eyes above the spinning or
twisting bobbins. The spindle rail carries the cap spindles with their bobbin
tubes and wharves and also the lifting rail and pokers. The bobbin tubes and
wharves rest on, and are moved up and down the cap spindle by, the lifting rail
which is supported on pokers working in guides in the spindle rail. Behind the
spindle rails, supported on the framing, is a rocking traverse shaft which operates
the pokers and lifting rails by means of pulleys and lifting chains.
As the
spindle wharves are lifted upwards by the traverse the bands in ordinary circum-
stances would become tighter and tighter. To overcome this and to regulate the
distance from the wharves to the cylinders and thus ensure equal tension on the
bands, no matter what height the wharves may stand at, we fix on the traverse
shaft a cam which acts upon the swinging levers carrying the spindle rails. This
cam is so formed and worked as to swing the spindle rail nearer to or farther
away from the cylinder as may be required. As the lifting rail is moving to its
higher point the spindle rail is swung inwards and on the lifting rail again
descending the spindle rail is swung outwards-the cam on the traverse shaft
acting in concert with the traverse and always regulating the distance between
the wharves and the cylinder. When frames are arranged so that all the spindles
on one side may be stopped for doffing without stopping the driving cylinder, the
cams which operate the swinging levers and spindle rail have a depression formed
in them. By turning the traverse shaft until this depression acts upon the swing-
ing levers the spindle rail assisted by a weight or spring is swung nearer to the
cylinder than when working and thus slackens the bands. At the same time
the wharves come in contact with brakes carried on the framing and are stopped.
In a second arrangement, applicable to ring and flyer spindles which are not

page_text: traversed up and down, the spindle rails are suspended on swinging levers as
in the arrangement described above. The swing arrangement is only used, how-
ever, to slacken or tighten the bands to overcome the influences of the weather
or to slacken the bands to brake and stop the spindles as described above.
this case the swing levers may be operated by cams on a shaft or simply bolted
to the framing at any required distance from the cylinders.
In
In a third arrangement applicable to spindles such as are described in both of
the foregoing arrangements the spindle rail is actuated by a spring or a weight
to cause it to continuously tension the bands by drawing the spindles away from
the cylinder.
The spindle rail may be continuous or made in sections each carrying a group
of spindles or each spindle may be carried on a separate rail or support which is
actuated as above described to maintain the requisite tension on the driving band.
In the whole of those arrangements there may be one band for each spindle or
for two or more spindles and one or more tin cylinders may be employed.
The second part of our invention relates to improved means of making and
fixing cap spindles in the spindle rails for economy and also with the object of
overcoming the vibration on those spindles. Hitherto cap spindles have been
made by reducing a heavy bar of steel leaving a thick part at the foot by which
the spindle is held in the rail. With the view of using a much stiffer quality of
steel which might be injured in forging we employ a piece of parallel steel and
we drive it into a foot step which is secured in the spindle rail in the usual way.
In another arrangement the footstep is bored parallel and is sawn through on
one side. The outside of the foot step is tapered to fit a tapered hole in the spindle
rail and on its lower end is a screw and nut by which the foot step is drawn into
the rail and at the same time made to clamp the cap spindle.

Improvements in Spinning, Twisting, and Winding Frames for
Fibrous Materials, and in the Regulating the Tension of Spindle
Bands for same.
We, THOMAS ALEXANDER BOYD and J. & T. BOYD, LIMITED, both of Shettleston
Iron Works, Shettleston, Lanarkshire, do hereby declare the nature of this inven-
tion 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 in spinning, twisting and winding frames
for fibrous materials and in the regulating the tension of spindle bands for same.
In the accompanying two sheets of drawings which illustrate our invention,
Fig. I is a side elevation of a cap spindle, driving cylinder, swing lever and
spindle rail. Fig. II is a side elevation of cap spindle and swing rail shewing
the means of slackening the bands and braking the spindle. Fig. III is a side
elevation of a flyer spindle with swinging rail shewing means of tightening or
slackening the bands by means of a shaft and cams. Fig. IV is a side elevation
of a spindle with swinging rail and back balance weight to tension the bands
continuously.

page_text: The first part of our invention relates to means of regulating the tension of
spindle bands and of stopping groups of spindles by slackening the bands and
braking the spindles.
Referring to Figs. I and II of the accompanying drawings, we shall first
describe one arrangement of this part of our invention, applicable to cap frames
in which the wharves are moved up and down by the lifting rail, thus altering
the distance from the wharve to the cylinder and also the tension of the bands.
In doing so we employ a central driving cylinder 1 passing throughout the
length of the frame. In front of the cylinder 1 and parallel with it we suspend
a spindle rail 2 fixed to the lower end of swinging arms 3 centred on the line 31
passing through the thread eyes above the spinning or twisting bobbins 4. The
spindle rail 2 carries the cap spindles 5 with their bobbin tubes and wharves 6
and also the lifting rail 7 and pokers 8. The bobbin tubes and wharves 6 rest
on, and are moved up and down the cap spindle 5 by, the lifting rail 7 which is
supported on pokers 8 working in guides 9 in the spindle rail 2. Behind the
spindle rails 2, supported on the framing, is a rocking traverse shaft 10 which
operates the pokers 8 and lifting rails 7 by means of pulleys 11 and lifting
chains 11. As the spindle wharves 6 are lifted upwards by the traverse the
bands in ordinary circumstances would become tighter and tighter. To overcome
this and to regulate the distance from the wharves 6 to the cylinders 1 and thus
ensure equal tension on the bands, no matter what height the wharves may stand
at, we fix on the traverse shaft 10 a cam 12 which acts upon the swinging levers 3
carrying the spindle rails. This cam 12 is so formed and worked as to swing the
spindle rail 2 nearer to or further away from the cylinder as may be required.
As the lifting rail 7 is moving to its higher point the spindle rail 2 is swung
inwards and on the lifting rail again descending the spindle rail is swung out-
wards the cam 12 on the traverse shaft acting in concert with the traverse and
always regulating the distance between the wharves and the cylinder. When
frames are arranged so that all the spindles on one side may be stopped for doffing
without stopping the driving cylinder, the cams which operate the swinging
levers and spindle rail have a depression 13, Fig. II, formed in them. By turning
the traverse shaft 10 until this depression 13 acts upon the swinging levers 3 the
spindle rail 2 assisted by a weight or spring is swung nearer to the cylinder 1 than
when working and thus slackens the bands. At the same time the wharves. 6
come in contact with brakes 14 carried on the framing and are stopped.
In a second arrangement, Figs. III and IV applicable to ring and flyer spindles
which are not traversed up and down, the spindle rails 2 are suspended on swing-
ing levers 3 as in the arrangement described above. The swing arrangement is
only used, however, to slacken or tighten the bands to overcome the influence of
the weather or to slacken the bands to brake and stop the spindles as described
above. In this case the swing levers 3 may be operated by cams 15 on a shaft 16
or simply fixed by bolts to the framing at any required distance.
In a third arrangement, Fig. IV, applicable to spindles such as are described
in both of the foregoing arrangements the spindle rail 2 is actuated by a spring
or a weight 17 to cause it to continuously tension the bands by drawing the spindles
away from the cylinder.
The spindle rail may be continuous or made in sections each carrying a group
of spindles or each spindle may be carried on a separate rail or support which is
actuated as above described to maintain the requisite tension on the driving band.
In the whole of those arrangements there may be one band for each spindle or
for two or more spindles and one or more tin cylinders may be employed.
The second part of our invention relates to improved means of making and
fixing cap spindles in the spindle rails for economy and also with the object of
overcoming the vibration on those spindles. Hitherto cap spindles have been
made by reducing a heavy bar of steel leaving a thick part at the foot by which
the spindle is held in the rail. With the view of using a much stiffer quality of
steel which might be injured in forging we employ a piece of parallel steel 5,

page_text: (Fig. 1) and we drive it into a foot step 51 (Fig. I) which is secured in the
spindle rail in the usual way.
In another arrangement the foot-step is bored parallel and is sawn through on
one side. The outside of the footstep is tapered to fit a tapered hole in the spindle
rail and on its lower end is a screw and nut by which the footstep is drawn into the
rail and at the same time made to clamp the cap spindle.
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. In spinning, twisting or winding frames a spindle rail movably secured on
the machine framing and adapted to be moved by hand or automatically for the
purpose of tightening or slackening the spindle driving band or bands.
2. In spinning or twisting frames a spindle rail or support movably secured
on the machine framing and adapted to be moved in relation to or in conjunction
with the point at which the yarn is guided above the spinning or twisting bobbin
for the purpose of tightening or slackening the spindle driving band or bands.
3. In spinning, twisting or winding frames a spindle rail or support movably
secured on the machine framing in combination with a cam or like means acting
thereon to move it automatically in concert with spindle wharves which are
traversed up and down, for the purpose of ensuring a regular tension on the
bands which drive the wharves.
4. In spinning, twisting or winding frames a spindle rail movably secured on
the machine framing and adapted to be moved by hand or automatically for the
purpose of tightening or slackening the spindle driving band or bands, in com-
bination with a brake arranged to stop each spindle.
5. In spinning or twisting frames the combination of a movable spindle rail
and swinging levers to carry same nearer to or further from the cylinder which
drives the spindles.
6. In spinning or twisting frames the combination of a movable spindle rail
with swinging levers carrying same, bands for driving the spindles from a driving
cylinder and a weight for tensioning the band or bands.
7. In spinning and twisting frames the improved cap spindle constructed of a
parallel steel spindle secured in the footstep as described.
