I, HOWARD PRIESTMAN, of Ashfield Mills Bradford, Yorkshiro Spinner and
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention has reference to machinery employed in spinning twisting, and
doubling yarns.
33
Hitherto the yarns in this class of machinery after leaving the feed or delivery
rollers, pass through an eyelet board and from thence to a bobbin or spool placed upon
a vertical spindle, and in practice it is found that a short length of yarn after leaving
the "nip of the feed rollers, bears upon the periphery of the bottom roller, and
this arises in consequence of the yarn having to travel (during a portion of its way
to the bobbin) almost in a vertical line consequently the length of yarn into which
twist can be put, is diminished by that portion of yarn resting upon the periphery
of the bottom feed roller.
To obviate this is the object of my invention, which I accomplish by placing the
spindle or stud and bobbin at an angle or in an oblique position pointing towards
the nip of the rollers so that immediately the yarn leaves the nip of the feed rollers
it is free and does not touch upon the bottom roller thereby permitting twist to be
put into the yarn throughout the whole length of such yarn which lies between "nip"
and the cap or flyer..
By this means I dispense with the eyelet board and get more twist into the yarn
than formerly; consequently finer counts can be spun and the yarn is not now
flattened by frictional contact with the bottom roller, but is left in a round state.

Improvements in Machinery for Spinning, Twisting, and Doubling
Yarns.
I, HOWARD PRIESTMAN, of Ashfield Mills, Bradford, Yorkshire, Spinner and
Manufacturer, do hereby declare the nature of this invention and in what manner the
same is to lie performed, to be particularly described and ascertained in and by the
following statement :-
My invention has reference to that class of machinery where flyers, caps, cups, or
rings and travellers are employed for spinning, twisting, and doubling yarns.
Hitherto the yarns in this class of machinery, after leaving the front or delivery
rollers, passed through an eyelet board and from thence to a bobbin or spool placed
upon a vertical spindle or stud and in practice it is found that a short length of yarn
after leaving the "nip" of the delivery rollers, bears upon the periphery of the
bottom roller; and this arises in consequence of the yarn having to travel (during a
portion of its way to the bobbin) almost in a vertical line, consequently the length of
yarn into which twist can be put is diminished by the length of that portion of yarn
resting upon the periphery of the said bottom of roller.
To obviate this is the object of my invention, which I accomplish by placing the
spindle or stud and bobbin at such an angle or in such an oblique position in relation
to the front rollers as to prevent the yarn from bearing upon the upper surface of the
bottom roller after the said yarn leaves the nip of the front or delivery rollers, so
that such yarn is now at liberty to take in the "twist" immediately on leaving the
nip and not, as hitherto, after passing over or resting upon the bottom roller or eyelet
board; and in this manner by my invention "twist" can be put into the yarn
throughout the whole length thereof which lies between the "nip and the cop or
flyer.
Such being the nature and object of my invention, I will now shew by the accom-
panying drawings how the same may be performed or put into practical operation.
Fig. 1 of the drawings hereto annexed illustrates such parts of a spinning or twisting
frame as is necessary to shew the application of my invention, wherein A is the
framework of the machine and B the bobbins containing the roving to be spun or
twisted. The said roving passes through guide eyes C, back rollers D and front or
delivery rollers E, all arranged in the ordinary manner, and until now, worked in
combination with vertical spindles F, as shewn in Fig. 2, where it will be seen that a
portion of the yarn, in passing from the delivery rollers E, of necessity must rest
upon the periphery of the front bottom roller, as will be observed and understood
from Fig. 2.
It is my intention to prevent the yarn from resting upon the lower front roller,
and this effect by preferably placing the spindle F at about right angles to the
centres of the two front or delivery rollers, as shewn in Fig. 1, by which means the
eyelet board G in Fig. 2 is dispensed with, and the yarn is free and at liberty to
receive twist immediately after leaving the nip of the front rollers, consequently, as

page_text: is obvious to those conversant with spinning and twisting, more even twist can be
put into the yarn than formerly, and thus the spinning is much improved and finer
counts can be spun from the same quality of fibre, whilst the yarn is not now flattened
by frictional contact with the bottom roller, as hitherto, but is left in a round state.
The method of driving the spindle is necessarily somewhat different to what was
the case when driving vertical spindles, but the method shown in Fig. 1 is sufficient
for the purpose. It will be seen that H is the main driving cylinder, I and J being
tension pulleys, the former working upon a fixed stud and the latter carried by a
bracket K working upon the stud L, the said bracket being weighted at M for the
purpose of keeping the driving tape N at a suitable tension.
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 :-
In machines having flyers, caps, or rings and travellers, for spinning, twisting, or
doubling yarn, the arrangement therein of spindles placed at such an angle to the
combined centres of the front rollers, as will prevent the yarn from resting upon the
front bottom roller, for purposes and in manner substantially as berein described
and shewn in the drawings.
