Improvements in or connected with Machinery for Preparing or Spinning Cotton or other Fibrous Materials.

page_text: 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 refers to the rollers and roller stands of mules and jack roving
and other frames employed in the spinning and preparing of fibrous materials.
It has hitherto been customary to place a top roller over each of the fluted
bottom rollers with cap bars or other device to maintain the rollers in position.
I find however that by applying a single top roller to press upon the two back
bottom rollers better results are obtained and the middle set of top rollers is
dispensed with thereby reducing the cost.
I construct the roller stand preferably with the front and middle rollers placed
on the same plane or level but I place the back roller on a different plane or lower
level and the slide which carries it is capable of adjustment horizontally and
vertically.
I place a single top roller to rest upon or against both the middle and back
bottom rollers the distribution of the weight or pressure of the top upon the
middle and back bottom rollers being adjusted by the difference in the height or
level of the two rollers and the distance between them.
A blade or strip of metal is placed between the ends of the top roller to prevent
longitudinal movement. This blade may be affixed to either of the slides or to
other part of the roller stand or in any other convenient position.
This arrangement enables the top roller to maintain its position without any
guides or brackets and I am enabled to dispense with the cap bars and their nebs.

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 and in what manner
DQ71

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention refers to the rollers and roller stands of mules and ring and
flyer spinning frames and roving or other frames employed in the spinning and
preparing of fibrous materials.
It has hitherto been customary to place a top roller over each of the fluted
bottom rollers with cap bars or other device to maintain the rollers in position.
I find however that by applying a single top roller to press upon the two back
bottom rollers better results are obtained and the middle set of top rollers is
dispensed with thereby reducing the cost.
The invention will be fully described with reference to the accompanying
drawings.
Fig. 1. Transverse sectional elevation of rollers and stand.
Fig. 2. Elevation of same from the back.
Fig. 3. Transverse sectional elevation of rollers showing a modified arrangement
of bottom rollers.
The stand A and antifriction supporting roller shaft B for the front roller are
constructed and arranged as described and claimed in the specification of my
carlier application for patent No. 22159 of 1896.
For the purposes of the present invention I construct the slides a and a¹ of the
sland A so as to place the middle roller C preferably in a different plane
Horizontally to the back roller D the back roller being lower. The slide a which
carries the back roller may be capable of adjustment to and from the slide a and
may also be made adjustable vertically. The middle and back bottom rollers may
either be fixed or adjustable horizontally and vertically in relation to each other
and separately or together in relation to the front roller either horizontally or
vertically.
I place a single top roller E to rest upon or against both the middle bottom
roller C and back bottom roller D the distribution of the weight or pressure of
the top roller E upon the middle hottom roller C and hack bottom roller D being
adjusted by the difference in height or level of the two rollers and the distance
between them.
The back roller D is preferably below the middle one C to give more weight
upon the back roller. Both may however be on the same level where no draught
is required between the back and midille rollers. The position of the single back
top or pressing roller E against the middle roller C maintains it parallel to the
bottom rollers and obviate the necessity for any cap bar or neb for the purpose.
The back roller D may be raised above the middle roller if an antifriction roller
is employed to keep the top or pressing roller in position.
The front roller F and the middle bottom roller C may be placed at same height
or horizontal level as in Fig. 1 or the middle bottom roller may be placed at a
higher level than the front one as in Fig. 3 or it may be placed at a lower level.
A bracket or blade of metal G is placed between the ends of the top rollers E
to prevent longitudinal movement. This bracket G is affixed to either of the
slides or to other part of the roller stand or in any other convenient position.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. In machinery for preparing and spinning cotton and other fibrous materials
the combination with middle and back bottom rollers of a single top pressing roller
resting upon the back bottom roller and bearing against the middle bottom roller
Ly which it is held in position parallel to both bottom rollers substantially as and
for the purpose described and shown.
2. In machinery for preparing and spinning cotton and other fibrous materials
the combination with middle and hack bottom rollers of a single top pressing roller

page_text: supported by the two bottom rollers and a bracket inserted between the ends of
the top rollers at intervals to prevent longitudinal movement substantially as and
for the purposes described.
