I JOHN CHARLES WALKER of Shipley Fields Mill, Shipley near Bradford in the
County of York Mechanical Engineer do hereby declare the nature of said
invention for "IMPROVEMENTS IN MACHINERY FOR COMBING WOOL, COTTON, SILK,
FLAX AND OTHER FIBROUS SUBSTANCES," to be as follows:―
My improvements are applicable to the so called "Nobles" and other kindred
combing machines. For the purpose of heating the material previous to its
passing into the comb circle I mount a steam chest between the under side of the
feed boxes or conductors and the upper side of the rack on which the large circles
are fixed, placed in such a position that the material as it passes to the comb is in
such close contact there with as to become heated; or instead of direct contact of
material with the aforesaid steam chest, I cause the conductors or boxes through
which it is led to the combs, to be in such close contact with the steam chest as to
become heated thereby, such heat being communicated to the material passing to
the combs.
I use wheels with "skew" or helical teeth for transmitting motion to the
combs; that is to say, the teeth on the rack circle and those in the pinion for
driving the same are made "skew" or helical I also gear the drawing off rollers
together with helical or skew wheels.
By the above arrangement all slipping or back lash is prevented and greater
steadiness of the machine produced.
To prevent the drawing off rollers from being pressed too close up to each other
by the springs, and thereby injuring the leathers I provide adjustable nuts
arranged in such a manner with regard to the spindles on which the spiral springs
are placed that by coming in contact with flanges or projections on such spindles,
the rollers are prevented from being pressed too closely together preventing
thereby injury to the leathers.

I, JOHN CHARLES WALKER of Shipley Fields Mill, Shipley near Bradford in the
County of York, Mechanical engineer do hereby declare the nature of said
invention for IMPROVEMENTS IN MACHINERY FOR COMBING WOOL, COTTON, SILK,
FLAX AND OTHER FIBROUS SUBSTANCES" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
"
My improvements are applicable to the so called Nobles" and other kindred
combing machines. For the purpose of heating the material previous to its passing
into the comb circle I mount a steam chest between the under side of the feed
boxes or conductors and the upper side of the rack on which the large circles are
fixed, placed in such a position that the material as it passes to the comb is in
such close contact there with as to become heated, or instead of direct contact of
material with the aforesaid steam chest, I cause the conductors or boxes through
which it is led to the combs, to be in such close contact with the steam chest, as to
become heated thereby, such heat being communicated to the material passing to
the combs.
I use wheels with "skew" or helical teeth for transmitting motion to the combs,
that is to say, the teeth on the rack circle and those in the pinion for driving the
same are made skew or helical. I also gear the drawing off rollers together with
helical or skew wheels.
By the above arrangement all slipping or back lash is prevented and greater
steadiness of the machine produced.
To prevent the drawing off rollers from being pressed too close up to each other
by the springs, and thereby injuring the leathers I provide adjustable nuts
arranged in such a manner with regard to the spindles on which the spiral springs
are placed that by coming in contact with flanges or projections on such spindles,
the rollers are prevented from being pressed too closely together, preventing
thereby injury to the leathers.
And in order that my invention may be more completely understood reference
is given to the accompanying drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional elevation and Fig. 2 a plan looking on the top shewing my
arrangement for heating the material previous to its passing to the comb circle.
Fig. 3 is a part sectional elevation. Fig. 4 a plan looking on the top, and Fig. 5 a
part enlarged view shewing arrangement for adjusting the drawing off rollers.
I mount the steam chest a between the underside of the feed boxes b and the
upper side of the rack plate c on which the large comb circle d is fixed.. On the
top of this steam chest a and between it and the feed boxes b is mounted
the incline e of ordinary construction. The steam chest a may receive its steam

page_text: through the hollow bent stud f whereby it is also attached to the bracket h which
is of ordinary construction and held in a stationery position with the incline e.
By the above arrangement I cause the conductors or feed boxes through which
the material is led to the combs, to be in such close contact with the steam chest a
as to become heated thereby, such heat being communicated to the material passing
to the combs,
"
I use wheels with " skew or helical teeth for transmitting motion to the
combs, that is to say, the teeth on the rack circle and those in the pinion for
driving the same are made skew or helical, I also gear the drawing off rollers
together with helical or skew wheels. By the above arrangement all slipping or
back lash is prevented and greater steadiness of the machine produced.
In order to prevent the drawing off rollers i and j from being pressed too close
up to each other by the spring k and thereby injuring the leathers I provide
adjustable nuts and m arranged and applied as shewn in connection with the
spindle n on which the spiral spring are placed, that by coming in contact with
the flanges or projections on such spindles the rollers i and j are prevented being
pressed too closely together.
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
1st The arrangement and application of circular steam chest between the feed
boxes and large circle comb plate for the purpose of heating the material previous
to its passing to the comb, substantially as herein set forth.
2nd The employment of wheels or gearing with skew or helical teeth on the
rack circle and pinion for driving the same, substantially as and for purposes
herein set forth.
3rd The employment of skew or helical wheels for gearing the drawing off rollers
substantially as and for purposes herein set forth.
4th The arrangement and application of adjustable nuts on the adjusting screw
spindles of the drawing off rollers, to prevent such rollers being pressed too closely
up to each other by the springs, substantially as and for purposes herein set forth.
Dated this 8th day of October 1885.
