IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER FIBRES
Year: 1878

page_text: LETTERS PATENT to Robert Haddon, James Dyson, and Edward Asţin, all of
Halifax, in the County of York, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR COMBING WOOL AND OTHER FIBRES."
Sealed the 4th October 1878 and dated the 4th April 1878.
PROVISIONAL SPECIFICATION left by the said Robert Haddon, James Dyson
and Edward Astin at the Office of the Commissioners of Patents on the 4th
April 1878.
ROBERT HADDON, JAMES DYSON, and EDWARD ASTIN, all of Halifax, in the County
of York. "IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER
FIBRES."
This Invention has special reference to that class of combing machine known as
"Noble's combing machine," the object of the Invention being to clean the teeth of
the circular combs, or to prevent noil or dirt from accumulating in the teeth of such
combs.
Our improvements consist in the use and employment of an upright endless
travelling belt, by preference having projections thereon placed at suitable distances
apart, so that as the belt is moving upwards these projections come in contact with
the inner or outer rows of the teeth of the combs, scraping or rubbing the loose fibre
upwards, which is afterwards entirely removed by the usual noil lifters and drawing-
off rollers.
The travelling belt may be driven from the usual rack underneath the circles of
this class of combing machine, but may be driven from other convenient parts of the

page_text: machine. This cleaning belt may be employed to clean both the large and small
circles of a Noble's machine, and is equally applicable to other kinds of combing
machines in which revolving circular combs are employed.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Richard Haddon, James Dyson, and Edward Astin in the Great Seal 5
Patent Office on the 4th October 1878.
ROBERT HADDON, JAMES DYSON, and EDWARD ASTIN, all of Halifax, in the
County of York. "IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER
FIBRES."
This Invention has special reference to that class of combing machine known as 1
"Noble's combing machine," the object of the Invention being to clean the teeth of
the circular combs, or to prevent noil or dirt from accumulating in the teeth of such
combs.
Our improvements consist in the use and employment of an upright endless
travelling belt, by preference having projections thereon placed at suitable distances 1
apart, so that as the belt is moving upwards these projections come in contact with
the inner or outer rows of the teeth of the combs, scraping or rubbing the loose fibre
upwards, which is afterwards entirely removed by the usual noil lifters and drawing-
off rollers.
The travelling belt may be driven from the usual rack underneath the circles of 2
this class of combing machine, but may be driven from other convenient parts of the
machine. This cleaning belt may be employed to clean both the large and small
circles of a "Noble's machine," and is equally applicable to other kinds of combing
machines in which revolving circular combs are employed.
In order that our Invention may be more fully understood we herein give 2
reference to the accompanying Sheet of Drawings illustrative thereof.
Fig. 1 is a side elevation of our apparatus attached to the large circle.of a Noble's
comb; Fig. 2 is an elevation of sanie as seen from inside of circle; and Fig. 3 is a
plan view of the large circle, shewing the apparatus in position.
A is an endless belt having projections a formed of leather or other suitable 3
material. The belt passes over two rollers or pulleys B and C, which are carried
in the brackets D and E fixed to the steam chest F. The driving is effected by
bevel wheels G, G', the stud carrying the wheel G₁ having at the other end a
toothed wheel H which gears with the ordinary rack K employed for driving the
large circle. The brackets D and E are joined by bolts c, d, the latter of which 3
passes through a slot c, so that the bolt c forms a fulcrum or hinge upon which the
bracket D may turn, so as to be placed to any required position or inclination. An.
adjusting or stretching plate M is also provided, which, by means of thumbscrew N,
can be caused to press against the belt, so as to tighten the same when it
becomes slack, or to adjust the projection to the teeth of the comb with greater 4
nicety and more readily than can be done by moving the pulleys.

page_text: It will be readily seen that our apparatus may be applied to all circular combs,
the driving arrangement being modified according to circumstances.
Having now described the nature of our Invention and shewn by Drawings how
the same may be performed or put into practice, we would have it understood that
we do not confine ourselves to the precise details of construction, as herein shewn,
but what we claim as our Invention and believe to be new is, the adjustable
travelling bolt A, in the manner and for the purpose substantially as herein shewn
and described.
In witness whereof, we, the said James Dyson and Edward Astin, for and on
bebalf of ourselves and the said Robert Haddon, have hereunto set our hands
and seals, this Second day of October, in the year of our Lord One thousand
eight hundred and seventy-eight.
