IMPROVEMENTS IN MACHINERY FOR COMBING WOOL, COTTON, FLAX SILK AND OTHER FIBROUS SUBSTANCES
Year: 1883

page_text: LETTERS PATENT to John Henry Whitehead of the firm of Taylor Wordsworth
and Company of Leeds in the County of York for an Invention of
"IMPROVEMENTS IN MACHINERY FOR COMBING WOOL, COTTON, FLAX SILK
AND OTHER FIBROUS SUBSTANCES
"
PROVISIONAL SPECIFICATION left by the said John Henry Whitehead at
the Office of the Commissioners of Patents on the 30th June 1883.
John Henry Whitehead of the firm of Taylor Wordsworth and Company of
Leeds in the County of York "IMPROVEMENTS IN MACHINERY FOR COMBING
WOOL, COTTON FLAX, SILK AND OTHER FIBROUS SUBSTANCES
My improvements have reference to combing machines in which drawing-off
rollers and leathers are employed for drawing off the fibres from the pins of the
combs, the object being to provide an arrangement whereby the roller stands can
be retained in position and also readily released when the leathers require
changing or when anything occurs in which the rollers and leathers require
attention.
Hitherto the roller stands have been carried and fixed together by screws or
bolts so that when the leathers or rollers required removing or otherwise attending
to a considerable loss of time was caused in unscrewing or releasing the stands
and in stopping the machine.
In order to remedy this defect I secure the top stands by means of a lock catch
or catches, springs or cotters to the upright bars, such upright bars being fixed to
the bottom stand in the ordinary way. By this arrangement the top stand is
easily and quickly released by the hand of the attendant so that the leathers or
rollers can be changed or removed or otherwise attended to when required.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Henry Whitehead in the Great Seal Patent Office on the
29th December 1883.
JOHN HENRY WHITEHEAD of the firm of Taylor Wordsworth and Company of
Leeds in the County of York "IMPROVEMENTS IN MACHINERY FOR COMBING
WOOL, COTTON, FLAX, SILK, AND OTHER FIBROUS SUBSTANCES."
My Improvements have reference to combing inachines in which drawing-off
rollers and leathers are employed for drawing off the fibres from the pins of the

page_text: combs, the object being to provide an arrangement whereby the roller stands can
be retained in position and also readily released when the Icathers require
changing or when anything occurs in which the rollers and leathers require
attention.
Hitherto the roller stands have been carried and fixed together by screws or 5
bolts so that when the leathers or rollers require removing or otherwise attending
to a considerable loss of time was caused in unscrewing or releasing the stands
and in stopping the machine.
In order to remedy this defect I secure the top stand by means of a lock, catch
or catches, spring or cotters to the upright bars, such upright bars being fixed to 1
the bottom stand in the ordinary way. By this arrangement the top stand is
easily and quickly released by the hand of the attendant so that the leathers or
rollers can be changed or removed or otherwise attended to when required.
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 front elevation, and Fig 2 a plan looking at the top showing
arrangement of my Invention.
a is the bottom stand having an upright bar b attached thereto by means of
screws or bolts c in the ordinary way.
The upper stand d is secured to the vertical bar b by means of the stud c, and
catch f, by this arrangement the top stand d is easily and quickly released by
withdrawing the catch f away from the stud e (which it embraces when the
stand d is fixed in position as shewn.) This operation is effected by the attendant,
so that the leathers and rollers can be changed or removed or otherwise attended
to when required without difficulty, or much loss of time.
In the arrangement of catch and stud e for retaining the top stand & shewn,
the slot in the catch fis formed to such a curve, that it tightens against the stud e
when pushed over the latter, being thereby firmly retained in position. .
Having now described the nature of my said Invention and shewn with the aid
of drawings how the same may be carried into practice I would have it understood
that I do not limit myself to the precise details or configuration of the parts I have
described and shewn as the same may be varied or modified without departing
from the nature of my said Invention; what I do claim is :—
The arrangement, construction, and application of roller stand & and incans
employed whereby the same can be readily retained in position or released,
substantially as and for the purpose herein set forth.
In Witness whereof I the said John Henry Whitehead have hereunto
set my hand and seal this twelvth day of November in the year of Our
Lord One thousand eight hundred and eighty three.
