I ISAAC HOLDEN, M.P. of Oakworth House Keighley in the County of York,
and of the firm of Isaac Holden & Sons, of Bradford in the same County, Wool
Combers do hereby declare the nature of my invention for IMPROVEMENTS IN
APPARATUS EMPLOYED IN COMBING WOOL AND OTHER FIBRES, to be as follows:-
These improvements have for their object to facilitate the working of, and whilst
strengthening, to ensure the correct and accurate adjustment of the parts of, the
square motion and circle comb in square motion combing machinery.
In working wool in combing machinery with what are known as square motion
combing machines comb bars in series rise; pass their teeth into the fibre; pass on
in their place in the series; are lowered; pass back and repeat their operation
being impelled forward or away from the circle comb by push pieces or slides and
these bars are driven by the push bars operating on the comb bar ends to force
them onward in their proper order, combing the "beard" of the wool on the comb
circle and straightening it as is well understood, but it is found in practice,
especially when employing comb bars of narrow section that they are apt to be
strained out of their true, or original shape, or curvature and by such deflection
the operation correctly of the machine is interferred with.
To overcome this evil the depth of the comb teeth bars has been increased to
give greater body of metal for stiffness, or rigidity, to resist this flexure, but this
greater depth is at once attended by another inconvenience, in that the extent of
lift required for the bars, from lower to upper series and vice versa is much greater,
and provision has to be made accordingly for the greater amount of room taken up
with consequent loss of rapidity of actual working speed of the machine.
To overcome these evils I have constructed the push bar to extend substantially
across the face of the comb bars and to follow more, or less the contour of the face,
or side of the comb bar, which comes next the comb circle and thereby to afford
support and pushing force to each bar in its succession in the series without
developing any bending strain to the bars.
Another advantage attendant upon this arrangement is that bars may be
made shallower and lighter with consequent reduction of the distance through which

page_text: they have to be lifted and lowered in their traverse, from next the comb circle to
the rear; back to the front, or working point, and up to their work in penetrating
and combing the fibre; and great increase of speed of working is enabled to be
realized with steady correct operation.
I find it convenient to form this push bar deep and to form it so that it may
.press on the comb bars in turn below the line of the combs of the circle, the press
bar being cut away or formed to such circle comb at the proper place to permit the
circle to pass through to the desired extent for the delivery properly of the fibre
from the one to the other without loss of space.

I, ISAAC HOLDEN M.P. of Oakworth House Keighley in the County of York,
and of the firm of Isaac Holden & Sons, of Bradford in the same County, Wool
Combers do hereby declare the nature of my invention for IMPROVEMENTS IN
APPARATUS EMPLOYED IN COMBING WOOL AND OTHER FIBRES, and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement:-
These improvements have for their object to facilitate the working of, and whilst
strengthening, to ensure the correct and accurate adjustment of the parts of, the
square motion and circle comb in square motion combing machinery.
In working wool in combing machinery with what are known as square motion
combing machines comb bars in series rise; pass their teeth into the fibre; pass on
in their place in the series; are lowered; pass back and repeat their operation
being impelled forward or away from the circle comb by push pieces or slides and
these bars are driven by the push bars operating on the comb bar ends to force
them onward in their proper order combing the "beard" of the wool on the comb
circle and straightening it as is well understood, but it is found in practice,
especially when employing comb bars of narrow section that they are apt to be
strained out of their true, or original shape, or curvature and by such deflection the
operation correctly of the machine is interfered with.
To overcome this evil the depth of the comb teeth bars has been increased to
give greater body of metal for stiffness, or rigidity, to resist this flexure, but this
greater depth is at once attended by another inconvenience, in that the extent of
lift required for the bars, from lower to upper series and vice versa is much greater,
and provision has to be made accordingly for the greater amount of room taken up
with consequent loss of rapidity of actual working speed of the machine.

To overcome these evils I have constructed the push bar to extend substantially
across the face of the comb bars and to follow more, or less the contour of the face,
or side of the comb bar, which comes next the comb circle and thereby to afford
support and pushing force to each bar in its succession in the series without
developing any bending strain to the bars.
Another advantage attendant upon this arrangement is that bars may be made
shallower and lighter with consequent reduction of the distance through which
they have to be lifted and lowered in their traverse, from next the comb circle to
the rear; back to the front, or working point, and up to their work in penetrating
and combing the fibre; and great increase of speed of working is enabled to be
realized with steady, correct operation.

I find it convenient to form this push bar deep and to form it so that it
press on the comb bars in turn below the line of the combs of the circle, the
press
bar being cut away or formed to such circle comb at the proper place to permit the
circle to pass through to the desired extent for the delivery properly of the fibre
from the one to the other without loss of space.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a portion of a comb circle a in plan with the pushing bar b, a
comb bar c, pushing slide & and lifting slide e, with the frame side f, all arranged
according to my invention. Figure 2 shows an end view of the pushing bar b
Figure 3 a cross section of the fallers or comb bar c and other parts on the line ABE
of figures 1 and 2, c being the comb bars in the upper tier, c¹ those in the lower or
returning tier and Figure 4 is a similar cross section of the same on the line CD
Figure 1 the comb bars being here omitted.
It will be seen that according to my invention the push bar b extends sub-
stantially across the face of the comb bar c and follows the contour of that bar c 1
which comes next the comb circle a affording it the desired support and also
giving it the requisite pushing force, without distorting it or developing any
bending strain.
It will also be seen that I am able to construct these bars c shallower with
lightness and consequent economy of room and owing to the extent of lift required
take these bars from the one series or tier c or c¹ to the other respectively-the
working speed of the machine can be augmented as already explained.
In the drawings it is clearly shewn how the push bar 6 is formed deep and
adapted to press on the comb bars o in turn as they come under operation acting
on each below the line (1) of the combs of the comb circle à and furthermore the 2
cut away portion 61 of this bar b on the one side from (2) to (3) and on the
other side from (4) to (5) and downwards to the line (1) into which gap so left
the part of the comb circle a projects coming close up to the comb bar c
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 2
I claim is
The construction and use of parts of "square motion" combing machinery
operating substantially as set forth and shewn in the drawings,
