I, JAMES BARBOUR, of the Firm of Combe, Barbour, and Combe, Limited, of
Falls Foundry, Belfast, Ireland, Machinist, do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvements in the method of driving the drawing
rollers of spinning frames.
It is a well known fact that the drawing rollers of spinning frames have a ten-
dency to wear endways, and that their wood pressing rollers have a tendency to
wear endwise in an opposite direction to that of the drawing rollers.
The effect of this endwise wear is to cause the bosses of the drawing rollers and
the bosses of the pressing rollers to be out of line with one another, and as this
causes a portion of the periphery of the wood pressing roller to overlap and not
to bear upon the face of the drawing roller, a portion of the former not being
exposed to compression from its want of contact with the drawing roller does
not decrease in diameter through wear when working, and in this manner a ridge
or shoulder is formed on the wood roller which bearing on the edge of the draw-
ing roller, increases the tendency of the endwise wear on both the axles of the
drawing and pressing rollers, and causes great wear and tear in the machine in
addition to decreasing its efficiency.
The object of this invention is to obviate these defects and is carried into effect
by the combination and use of drawing roller driving wheels with their driving
teeth set at an inclination to the axis of rotation, the inclination being in such
a direction that the pressure on the teeth necessary to revolve the drawing rollers
has also a tendency to push the drawing rollers endwise but in a direction opposite
to that to which the drawing rollers naturally tend. The natural tendency of the
drawing rollers to move endwise being neutralized, they float freely in their bear-
ings without end pressure, and a great amount of wear and tear of the frame is
obviated, and a larger proportion of the bearing faces of the drawing rollers and
pressing rollers can be utilized.
The wheels with inclined teeth work with less vibration, as their coming in
contact and leaving one another is more gradual than with wheels in which the
teeth are parallel to the axis of rotation, and as a consequence there is a more
uniform delivery of the material.

page_text: I, JAMES BARBOUR, of the Firm of Combe, Barbour, and Combe, Limited, of
Falls Foundry, Belfast, Ireland, Machinist, do hereby declare the nature of this
invention 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 the method of driving the drawing
rollers of spinning frames.
It is a well know fact that the drawing rollers of spinning frames have a ten-
dency to wear endways and that their wood pressing rollers have a tendency to
wear endwise in an opposite direction to that of the drawing rollers. The effect
of this endwise wear is to cause the bosses of the drawing rollers and the bosses
of the pressing rollers to be out of line with one another and as this causes a
portion of the periphery of the wood pressing roller to overlap and not to bear
upon the face of the drawing roller a portion of the former not being exposed to
compression from its want of contact with the drawing roller does not decrease
in diameter through wear when working and in this manner a ridge or shoulder
is formed on the wood roller which bearing on the edge of the drawing roller
increases the tendency of the endwise wear on both the axles of the drawing and
pressing rollers and causes great wear and tear in the machine in addition to
decreasing its efficiency.
The object of this invention is to counteract this defect by the use and employ-
ment of skew driving wheels or wheels having their teeth set at an inclination
so that their tendency is to push the axis of the drawing rollers and consequently
the drawing rollers in a direction opposite to that to which they naturally tend
for the reason hereinbefore stated.
Such being the nature and object of my said invention the following is a com-
plete description of same reference being had to the accompanying drawings, in
which:
Fig. 1 is an end elevation shewing the drawing and pressing rollers the position
of the skew or inclined toothed driving wheels being indicated by the dotted lines.
Fig. 2 is a plan view of Fig. 1 the skew driving wheels being shewn in full.
According to this invention at 1-1 are the drawing rollers mounted on the
shaft or axis 2 and at 3-3 are the pressing rollers. On the drawing roller shaft
or axis 2 is mounted the skew driving wheel 4 and gearing with and driving
this wheel 4 is the intermediate driving wheel 5 the teeth of which are also skew
or set at an inclination to the axis of rotation. Heretofore the drawing
rollers 1-1 have had a tendency to move endwise in the direction indicated by
the arrow A in Fig. 2, but by employing the skew driving and intermediate
wheels 4-5 in combination with the drawing rollers 1 as described the tendency
is counteracted as the skew wheels 4-5 tends to move the shaft or axis 2 and
rollers 1-1 endwise in the direction indicated by the arrow B in Fig. 2. The
natural tendency of the drawing rollers 1-1 to move endwise being neutralized
they float freely in their bearings without end pressure and a great amount of
wear and tear of the frame is obviated and a larger proportion of the bearing faces
of the drawing rollers 1-1 and pressing rollers 3-3 can be utilized.
The driving and intermediate wheels 4-5 with inclined teeth work with less
vibration as their coming in contact and leaving one another is more gradual than
with wheels in which the teeth are parallel to the axis of rotation and as a con-
sequence there is a more uniform delivery of the material.

page_text: 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:-
The drawing rollers 1-1 and shaft or axis 2 combined with and driven by
skew or inclined toothed driving and intermediate wheels 4-5 as and for the
purpose herein described and substantially as illustrated by the annexed drawings.
