IMPROVEMENTS IN MACHINERY FOR COMBING WOOL, COTTON, FLAX, SILK AND OTHER FIBROUS SUBSTANCES "
Year: 1882

page_text: LETTERS PATENT to John Henry Whitehead, a partner in 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 7th November 1882.
JOHN HENRY WHITEHEAD, a partner in the firm of Taylor Wordsworth and
"IMPROVEMENTS IN MACHINERY FOR
Company of Leeds in the County of York
COMBING WOOL, COTTON, FLAX, SILK AND OTHER FIBROUS SUBSTANCES
"
My Improvements relate to the Invention of Robert Speight and Thomas Speight,
for which Letters Patent were granted to them and dated 11th June 1877 N° 2328
and entitled "Improvements in machinery or apparatus for combing wool and other
fibrous substances."
Further my Improvements have reference to that class of machines known as
"Noble's" combing machines and also to other combing machines where dabbing
brushes are employed and has for its object the dispensing with the separate
driving of each dabbing brush, and by these Improvements I am able to regulate
the time of the dabbing of the brushes into the combs in such a manner that one
may be at the top of its stroke and out of the comb whilst the other is dabbing the
wool into the combs. By such improvements there is a great saving in the wear
and tear of the machine, also the brushes can be worked at a much higher speed
than heretofore.
According to my Invention I provide a horizontal shaft across the machine and
on the ends of which are provided eccentrics. These eccentrics are so coupled or
connected with the slides to which the dabbing brushes are attached that by causing
them to rotate the required vertical reciprocating movement is imparted to the
dabbing brushes.
The rotary movement is imparted to the eccentrics from the horizontal shaft
which is actuated through the medium of one fast pulley mounted thereon, such

page_text: pulley being driven from the ordinary driving shaft; or the eccentrics may be placed
on the ends of the driving shaft, such shaft being lowered to any required position
for imparting motion direct to the dabbing brushes, and dispensing with the
intermediate shaft and belt.
By regulating the position of the eccentrics the timing of each dabbing brush is 5
effected and there is no possibility when so timed of the brushes coming into
operation simultaneously, the straining of the machine is thereby obviated.
.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
5th May 1883..
JOHN HENRY WHITEHEAD, a partner in 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 relate to the Invention of Robert Speight and Thomas Speight,
for which Letters Patent were granted to them and dated 11th June 1877 N° 2328
and entitled "Improvements in machinery or apparatus for combing wool and other
fibrous substances."
Further my improvements have referenco to that class of machines known as
"Nobles" combing machines whero dabbing brushes are employed, and has for its
object the dispensing with the separate driving of each dabbing brush, and by these
improvements I am able to regulate the time of the dabbing of the brushes into the
combs in such a manner that one may be at the top of its stroke and out of the
comb, whilst the other is dabbing the wool into the combs. By such improvements
there is a great saving in the wear and tear of the machine, also the brushes can be
worked at a much higher speed than heretofore.
According to my Invention I provide a horizontal shaft across the machine and
on the ends of which are provided eccentrics. These eccentrics are so coupled or
connected with the slides to which the dabbing brushes are attached that by causing
them to rotate the required vertical reciprocating movement is imparted to the
dabbing brushes.
The rotary movement is imparted to the eccentrics from the horizontal shaft
which is actuated through the medium of one fast pulley mounted thereon, such
pulley being driven from the ordinary driving shaft; or the eccentrics may be placed
on the ends of the driving shaft, such shaft being lowered to any required position
for imparting motion direct to the dabbing brushes and dispensing with the
intermediate shaft and belt.
By regulating the position of the eccentrics the timing of each dabbing. brush
is effected and there is no possibility when so timed of the brushes coming into
operation simultaneously, the straining of the machine is thereby obviated.

page_text: 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 part front elevation and Fig 2 a part side elevation of combing machine
with my improvements applied thereto.
a. a. are the dabbing brushes, those are carried on vertical slides b. b, fitted so as
to slide freely in bearings c. c. attached to the pillars d d. These pillars d d are of
ordinary construction. e is the driving shaft mounted in suitable bearings in the
top of the pillar d, this also is of ordinary construction. On the driving shaft e is
provided a fast pulley f. The required vertical reciprocating movement is imparted
to the dabbing brushes a, a, from the pulley f, on the driving shaft e, through
pulley g, shaft h, eccentric or crank i, connecting rod k, and adjustable link 7, and
slide b.
When preferred the shaft h may be driven from a pulley on a driving shaft,
placed in any convenient position, below the comb circle, instead of from the ordinary
driving shaft e.
By driving as shewn the brushes always retain their exact positions with regard
to each other, whereas previously when driven separately those positions were liable
to frequent changes, and not unfrequently performing the operation of dabbing
simultaneously, causing thereby a great strain on the machine.
Having now described the nature of my said Invention and described by drawings
how the same may be carried into practico I would have it understood that I do
not limit myself to the preciso 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 and application of the shaft h, and pulley g, for transmitting
motion from the driving shaft e, or other shaft in combination with the
eccentric or crank i, connecting rod k, adjustable link 1, and slide b,
substantially as berein setforth.
In Witness whereof, I, the said John Henry Whitehead have hereunto set my
hand and seal this twenty fourth day of April in the year of Our Lord one
thousand eight hundred and eighty three.
