PROVISIONAL SPECIFICATION.
Improvements in or connected with Machinery for Preparing or
Spinning Cotton or other Fibrous Materials.
I, SAMUEL WHITTAKER of Shipton Mill, Bolton, in the County of Lancaster,
Cotton Spinner, do hereby declare the nature of this invention to be as follows:-
This invention is designed to improve the running and render more easily driven
the front top rollers of mules, roving, jack and other frames employed in the
spinning and preparing of fibrous materials.
Hitherto these rollers whether weighted or not have been held in position by
cap bars and nebs or their equivalent which engage with the axles of the rollers. I
find however that by dispensing with such nebs and holding the rollers in place
by means of anti-friction discs or rollers I obtain better results in the running of
the rollers, less friction and also a greater top roller capacity in length and
consequently in weight for self weighted rollers.
In front of the rollers I place a shaft or roller running longitudinally of the
frame.
If a shaft is used I place upon it at intervals a number of discs the peripheries
of which bear against the uncovered part of the rollers and so placed that the
rollers lie against the discs and are maintained in position thereby. The discs
may bear against the covered portions of the rollers if found more convenient.
Instead of a shaft with discs a roller of uniform thickness may extend the length
of the frame and the covered portions of the rollers rest against it.
The antifriction discs or rollers are supported in brackets either formed as part
of the roller stand or. as separate brackets attached thereto or to the roller beam
and the brackets are of any suitable shape.
The friction rollers or discs may either run free or be driven at the same peri-
pheral speed as the bottom fluted roller or at a greater or less speed as may be
found more practical.
A blade may extend from the bracket between the ends of the rollers to take
up play and prevent longitudinal movement.
The essential feature of the invention consists in dispensing with the cap bar
and nebs and substituting therefor antifriction discs or rollers to support and keep
in position the front top rollers.

page_text: the same is to be performed, to be particularly described and'ascertained in and
by the following statement:-:
:.
This invention is designed to improve the running of and render more easily
driven the front top rollers of mules ring and flyer spinning frames and roving or
other frames employed in the spinning and preparing t fibrous materials.
Hitherto these rollers, whether weighted or not have been held in position by
cap bars and nebs or their equivalent which engage with the axles of the rollers.
Such cap bars and nebs have always been objectionable owing to the difficulty of
adjusting or aligning them to maintain the axis of the top 1ollers perfectly parallel
with the axis of the lower roller. I find however that by dispensing with such
nebs and holding the rollers in place by means of antifriction discs or rollers I
obtain better results in the running of the rollers, less friction and also a greater
top roller capacity in length and consequently in weight for self weighted rollers.
It will be fully described with reference to the accompanying drawings in which
the stand and rollers of a spinning or preparing frame are illustrated.
Fig. 1. Front elevation.
Fig. 2. Transverse section.
Fig. 3. Transverse section showing an arrangement for smaller.rollers..
Against the first or front top or pressing roller I place a shaft or roller A running
longitudinally of the frame mounted on suitable bearings B affixed to the roller
stands C. The shaft or roller A is preferably of small diameter and is provided
at intervals with a number of antifriction discs or collars D against the peripheries
of which the uncovered portion e of the front top rollers E bear but it may however
be of uniform diameter and the covered surface of the top rollers bear against it.
The shaft or roller A is so placed against the front top rollers E that they lie against
the discs D) or against the shaft or roller A and are thereby maintained in position
parallel to the bottom roller.
Instead of placing the shaft A or discs D. in front of the top roller as shown in
Fig. 3 they may be placed behind the rollers E which would then be placed behind
the vertical centre of the bottom roller F.
The antifrictional discs or rollers are supported in the brackets B either formed
as part of the roller stand C or as separate brackets attached thereto or to the roller
beam and the brackets are of any suitable shape.
same
The friction rollers A or discs D may either run free or be driven at the
peripheral speed as the bottom fluted roller For at a greater or less speed as may
be found more practical.
To the stands C blades or brackets G are affixed which extend between the
ends of the rollers to prevent longitudinal movement or travel of the top rollers E.
The essential feature of the invention consists in dispensing with the cap bar
and nebs and substituting therefore antifriction discs or rollers to support and keep
in position the front top rollers.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:
The improvement in machinery for preparing or spinning cotton or other fibrous
materials which consists in the combination with the front top rollers of a shaf
or roller placed against them to support and keep them in position substantially
as described.
