IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS EMPLOYED FOR COMBING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1881

page_text: LETTERS PATENT to Peter Crook Marsden and William Pendlebury, both of
Bolton, in the County of Lancaster, for an Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF APPARATUS EMPLOYED FOR COMBING COTTON AND
OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Peter Crook Marsden and
William Pendlebury at the Office of the Commissioners of Patents on the
29th October 1881.
PETER CROOK MARSDEN and WILLIAM PENDLEBURY, both of Bolton, in the
County of Lancaster. "IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS
EMPLOYED FOR COMBING COTTON AND OTHER FIBROUS SUBSTANCES."
This Invention relates principally to the construction of the combing cylinders
employed in machines for such purposes, the object of the Invention being to
increase the amount of work performed by such machines, and at the same time
to improve the quality of the work.
We make the comb cylinders by preference of larger diameter than usual, and
provide each cylinder with two comb sections and two fluted sections.
The combs in the comb sections are not all set at the same angle as usual, but
the front comb of each section is placed almost tangentially to the circumference,
the angle of each succeeding comb being gradually increased so that the last comb
of each section is at an angle of about sixty degrees.
By these means we are enabled to commence at once and to obtain a much more
effective combing than with the cylinders made in the usual manner.
The cam which actuates the steel roller we also make with a double set of
grooves to correspond with the four sections.
We also make the following cams double acting, namely:-The leather roller
cam, the feed cam, the top comb cam, and the nipping cam, and by these means
the whole of the combing process is performed twice at each revolution of the
combing cylinders instead of once only as heretofore.

PETER CROOK MARSDEN and WILLIAM PENDLEBURY, both of Bolton, in the
County of Lancaster. "IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS
EMPLOYED FOR COMBING COTTON AND OTHER FIBROUS SUBSTANCES."
This Invention relates principally to the construction of the combing cylinders
employed in machines for such purposes, the object of the Invention being to
increase the amount of work performed by such machines, and at the same time
to improve the quality of the work.
Such being the nature and object of our said Invention, we will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect; and in order that the same may be clearly understood we
have annexed hereunto a Sheet of Drawings illustrative thereof, and have marked
the same with figures and letters of reference corresponding with those in the
following explanation thereof.
Fig. 1 in the annexed Drawing is an end view (half size) of a "Heilmann"
combing cylinder constructed according to our Invention.
We make the comb cylinder a, a, Fig. 1 (by preference) of larger diameter than
usual, and provide_each_cylinder-with-two-comb-sections-b, b, and two fluted
sections c, c. The combs 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12, in the comb sections
are not all set at the same or nearly the same angle as usual, but the front comb 1
of each section is placed almost tangentially to the circumference, the angle of
each succeeding comb being gradually increased so that the last comb 12 of each
section is at an angle of about sixty degrees. By these means we are enabled to
commence at once and to obtain a much more effective combing than with cylinders
made in the usual manner.
We would here remark that this method of gradually increasing the angle of the
teeth is also applicable with advantage to the single section combs ordinarily
employed. The cam e, e, which actuates the steel roller we also make with a
double set of grooves and inclines to correspond with the four sections, see Figs. 2
and 3, which are views of the two faces thereof. We also make the following
cams double-acting, namely:-The leather roller cam f, f, Fig. 4, the feed cam g, g,
Fig. 5, the top comb cam h, h, Fig. 6, and the nipping cam i, i, Fig. 7, and by
these means the whole of the combing process is performed twice at each revolution
of the combing cylinder instead of once only as heretofore.
All the cams, Figs. 2, 3, 4, 5, 6, and 7, are shown on the Drawing one quarter
size.
We have above described the method of duplicating the action of the combing
cylinder and its adjuncts only, but we also propose in some cases still further to
increase the diameter of the combing cylinder and to multiply the action of the
cams still further so as to effect the combing process three times or oftener during
each revolution thereof.
Having now described the nature and object of our said Invention together with
the manner in which the same is to be or may be performed or carried into
practical effect, we wish it to be understood that we claim as our Invention,―
First. The use in combing cylinders of two or more comb sections and two or
more fluted sections, the teeth of the said combs being set at gradually increasing
angles, substantially as and for the purposes described; and
Secondly. We claim duplicating or multiplying the action of the working cams

page_text: in a corresponding degree, as above described, so that the whole of the combing
process is performed twice or oftener at each revolution of the comb cylinder
instead of only once, as heretofore.
In witness whereof, I, the said Peter Crook Marsden (on behalf of myself
and the said William Pendlebury), have hereunto set my hand and seal,
this Twenty fifth day of April, in the year of our Lord One thousand eight
hundred and eighty two.
PETER C. MARSDEN. (LS.)
