Year: 1881

page_text: LETTERS PATENT to Prince Smith, the younger, of Keighley, in the County
of York, Machine Maker, and Smith Ambler, of the said Keighley,
Draftsman, for an Invention of "IMPROVEMENTS IN SPINNING AND TWISTING
MACHINERY."
PROVISIONAL SPECIFICATION left by the said Prince Smith and Smith
Ambler at the Office of the Commissioners of Patents on the 8th June
1881.
PRINCE SMITH, the younger, of Keighley, in the County of York, Machine
Maker, and SMITH AMBLER, of the said Keighley, Draftsman. "IMPROVEMENTS IN
SPINNING AND TWISTING MACHINERY."
The object of our Invention is to obtain uniformity of tension upon the driving
bands or cords, by which motion is communicated from the driving cylinder in
spinning or twisting machinory to the tubes in cap frames or spindles in ring
frames.
Various attempts have, we are aware, been made to accomplish this object, but
hitherto with only partial success, and that not satisfactory.
Our improvements consist in effecting the required vertical motion to the driving
cylinder direct from the vertical motions of the lifter rails, so that the tension on
the driving bands or cords from such driving cylinder remains uniform.
The lifter rails are operated by their lifter chains and heart motion somewhat as
usual, and simultaneously by racks and pinions corresponding motions are com-
municated to sliding supports and bearings for the axis of the driving cylinder.
These sliding supports move in suitable guides in the main framing, and they
are counterweighted.
As the axis of the driving cylinder moves vertically, the pulley or drum thereon
is driven by a belt or strap, and uniformity of tension thereto is secured by a pair
of guide wheels acting on such belt or strap.
When bobbins have been filled, and change or dofting of them has been effected,
the lifter rail and parts are brought back simultaneously for cach side of the frame
by a cross shaft, tooth gear, and shifting pinions. Corresponding motion is at the
same time secured to the driving cylinder.
By these means no separate alteration of position or speed for different counts
of yarn is required, and to change from spool to common bobbin the heart motion
is changed in the usual way.

PRINCE SMITH, the younger, of Keighley, in the County of York, Machine
Maker, and SMITH AMBLER, of the said Keighley, Draftsman. "IMPROVEMENTS IN
SPINNING AND TWISTING MACHINERY."
The object of our Invention is to obtain uniformity of tension upon the driving
bands or cords by which motion is communicated from the driving cylinder in
spinning or twisting machinery to the tubes in cap frames or spindles in ring
frames.
Various attempts have, we are aware, been made to accomplish this object, but
hitherto, with only partial success, and that not satisfactory.
Our improvements consist in effecting tho required vertical motions to the
driving cylinder direct from the vertical motions of the rails for lifting and
lowering the cap tubes or other spindles, so that the tension on the driving bands
or cords from such driving cylinder remains uniform.
The lifter rails are operated by their lifter chains and heart motion somewhat
as usual, and simultaneously by racks and pinions corresponding motions are com-
municated to sliding supports and bearings for the axis of the driving cylinder.
These sliding supports move in suitable guides in the main framing, and they
are counterweighted.
As the axis of the driving cylinder moves vertically, the pulley or drum thereon
is driven by a belt or strap, and uniformity of tension thereto is secured by a pair
of guide pullics acting on such belt or strap.
When bobbins have been filled, and change or doffing of them has been effected,
the lifter rail and parts are brought back simultaneously for each side of the
frame by a cross shaft, tooth gear, and shifting pinions. Corresponding motion is
at the same time secured to the driving cylinder.
By these means no separate alteration of position or speed for different counts
of yarn is required, and to change from spool to common bobbin the beart motion
is changed in the usual way.
But that the Invention may be the better understood, we will, by the aid of
the accompanying Drawings, proceed to describe means pursued by us in carrying
the same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an end view, and Figure 2 a side view of parts of machinery
arranged according to our Invention. Figures 3,-4, and 5 show end view, plan
view, and side view of parts at the opposite end of the machinery.
In each of the Figures the same letters indicate corresponding parts.
a, a, indicate parts of the main framing; b is the main cylinder for giving
inotion by means of bands or cords c to the spindles d of the caps e, as is well
understood, but according to our improvements the shaft or axis b' of the cylinder b
is supported at each end in bearings formed in pieces f, which are capable of
sliding vertically in adjustable guides formed for them in castings a' affixed to
and forming part of the main framing a. These sliding pieces are with the
ovlinder k. they support counter balanced by means of chains or bands f¹.

page_text: slides fare formed or applied racks f*, the teeth of which take into the teeth of a
pinion affixed to the boss f applied to the axis ; carrying the heart motion 1.
On this boss f is also formed or applied the tooth pinion ƒ, the teeth of which
take into the teeth of a rack g' formed on or applied to the horizontal sliding
bar g, which is supported by the pulleya g², so as to be capable of sliding freely
thereon, and on this bar g is also formed or applied a rack g³, the teeth of which
take into the teeth of a pinion g' applied to the axis g³, on which is also affixed
the pinions go, the teeth of which take into the teeth of racks h' formed on or
applied to the lifting rails h. At one end of the machine in place of the teeth of
the pinion f' taking into the teeth g' an intermediate wheel is used in order to
preserve the correct relative motions at the opposite end.
Thus are the motion of the lifter rails connected with the motions of the
horizontal rails g, and consequently with the vertical motions of the main
cylinder b.
.
The motion to the lifter rail h for the form or extent of cap required is effected
by the heart or such like motion in the usual way.
To the lifting rails h are connected the one end of chains or bands h³, which
pass over the stationary guide pulleys h³, and are at their other ends connected to
the vertical arms or supports of the rails i for acting upon to raise or lower the
spindle tubes d.
On the axis 6 of the main cylinder b are applied the ordinary fast and loose
pulleys to be driven by a band or strap 63, and in order to admit of the free
vertical motions of the cylinder b without interference with the uniform operation
of such band or strap, we apply the additional guide pulleys b', 6', to turn upon
axes or short studs supported by one of the sliding pieces f, and the driving band
or strap 63 is conducted partly around one of the guide pulleys 6, thence partly
around the pulley b³, thence partly around the other guide pulley be, and thence
partly around a pulley be applied to the axis 66, as indicated.
On the shaft or axis j is also applied the worm wheel k, the teeth of which take
into the teeth of the wheel affixed on a shaft or axis, which is supported to
revolve freely in the bearing l', and carries the tooth wheel 1, the teeth of which
take into the teeth of the intermediate wheel, the teeth of which take into the
teeth of the pinion applied to a hollow boss, which boss is applied to the
shaft by a feather, so that it may have free ond-way motion thereon and yet
rotate with that shaft. The shafts are alike at each side of the machine, and
each is capable of traversing and of revolving in a stationary socket, and at its
inner end it is formed with the screw, by which to operate on its rail h. By
these means the same relative vertical motions up or down are imparted to the
drum b and the rails i.
When bobbins have been filled, and change or doffing of them has been
effected, the rails h and parts connected thereto may be brought back simul-
taneously for each sido frame by shifting for the time the boss on the shaft 16, so
as to disconnect the pinion thereon from the teeth of the wheel, and bringing
the teeth of the bevil wheel m on that boss into gear with the teeth of the
bevil wheel n on the cross shaft n', which is supported to have rotary motion
given to it by suitable standards, and has applied to it for the purpose of its
rotation the hand wheel n².
Having thus described our Invention, and means which we adopt in carrying
the same into effect, we would have it understood that we do not confine ourselves
to the precise arrangements of parts as shown and described, as the same may be
varied without departing from the peculiar character of our improvements, but
what we do claim is,—
The arranging or combining parts of machinery employed in spinning and
twisting, whereby simultaneous vertical motions are obtained to main or driving
cylinders, and to the means for lifting and lowering the cap spindles or such like
spindles, so as to maintain uniform tension on the driving bands or cords from
such driving cylinder, substantially as described.

page_text: Also we claim arranging or combining parts whereby uniformity of motion to
the pulley or drum of the main cylinder is secured, substantially as described.
Also we claim the arranging or combining parts whereby facility is afforded for
change or doffing of the bobbins, substantially as described.
In witness whercof, we, the said Prince Smith and Smith Ambler, have
hereunto set our bands and seals, this Third day of December, One
thousand eight hundred and eighty one.
