IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER FIBRES
Year: 1877

page_text: LETTERS PATENT to Frederick Henry Wright, Worsted Spinner, of Halifax, in
the County of York, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
COMBING WOOL AND OTHER FIBRES."
Sealed the 20th October 1877, and dated the 1st May 1877.
PROVISIONAL SPECIFICATION left by the said Frederick Henry Wright at
the Office of the Commissioners of Patents on the 1st May 1877.
FREDERICK HENRY WRIGHT, Worsted Spinner, of Halifax, in the County of York.
"IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER FIBRES.'
My Invention relates to improved means of constantly changing the surface of
the belt or apron at the part which is presented for the passage of the wool or
fibres when "doffing," or taking the wool or fibres from the circular comb in the
form of a sliver, preventing the formation of grooves and facets in the belt or apron,
and producing a great saving in the wear and tear. For this purpose I employ a
rocking or oscillating roller which imparts to the leather belt or apron, at the part
presented for the passage of the wool or fibre, a constant rising-and-falling motion.
The roller is fitted on a spindle and works freely in a frame, which is made with an
arm having two bent projections, in which rovolves the ends of the roller spindle ;
in the centre of the arm is formed a boss, in which is fixed stud working in a
bearing formed in an upright lever fixed or formed on a bracket which is bolted to
the comb frame; the stud is made to pass through the bearing of the upright lever,
and on the stud is fitted a curved horizontal lever having at the end a slot hole,
through which is passed a bolt to secure an upright lever; the bottom end of this
lever rests on an excentric working on a shaft fitted in the machine. The excentric
gives a rising-and-lowering motion to the upright lever, imparting a rising-and-
lowering motion to the curved horizontal lever, producing a rocking or oscillating
movement of the roller, which constantly raises and lowers the belt or apron,
changing the surface.

FREDERICK HENRY WRIGHT, Worsted Spinner, of Halifax, in the County of York.
IMPROVEMENTS IN MACHINERY FOR COMBING WOOL AND OTHER FIBRES."
The said Invention relates to improved means of constantly changing the surface
of the belt or apron at the part which is presented for the passage of the wool or
fibres when "doffing," or taking the wool or fibres from the circular comb in the
form of a sliver, preventing the formation of grooves and facets in the belt or apron,
and producing a great saving in the wear and tear. For this purpose I employ a
rocking or oscillating roller which imparts to the leather belt or apron, at the part
presented for the passage of the wool or fibre, a constant rising-and-falling motion.
The roller is fitted on a spindle and works freely in a frame, which is made with an
arm having two bent projections, in which revolves the ends of the roller spindle;
in the centre of the arm is formed a boss, in which is fitted a stud working in a
bearing formed in an upright lever; this lever is bolted to a bracket on which is
cast or formed a boss which fits on the top of another boss formed on the rocking
slide; the bracket and slide are secured together by a set screw; the rocking slide
is worked by an excentric fitted inside the top of the stud plate of the combing
machine; the excentric is worked by a worm wheel or wheels actuated by the
rollers or shaft of the comb. The excentric gives a rocking motion to the slide,
which actuates a lever connected to a cranked lever fitted on the stud on which
is fitted the frame of the roller, producing a rocking or oscillating movement
to the roller, which constantly rises and lowers the belt or apron, changing the
surface.
But in order to enable my improvements to be better understood I will proceed
to more particularly the same by reference to the accompanying Drawing, in which
Figure 1 represents a front elevation of the improved apparatus, and Figure 2, a
side elevation of the same. Similar letters of reference are used to represent similar
parts.
A is the excentric fitted on a shaft B, which is fitted in suitable bearings fixed
on the top of the stud plate of the comb; this shaft is actuated by a worm wheel
or by wheels, which is or are worked by the rollers or shaft of the comb. The
excentric works in the slide C, giving the slide a rocking or oscillating action.
On
the top of the slide is cast or formed a boss D, on which is fitted the boss E of a
bracket F; this bracket is formed with lugs G, in which is fitted and secured the
bottom of a standard lever H, having at the top a boss I, in which is fitted a stud J,
and on which is fitted the centre boss Z of the frame K; this frame is made at the
top with projecting lugs L, in which is fitted the foot M of the top N of the frame K,
and which is secured in position by the set screw O. The frame top is made
moveable, to allow of removing the roller P, to place or take off the belt or apron Q.
The top and bottom of the frame K are made with bosses R and fitted with brass
bushes S, in which revolve the ends T of the roller spindle U. On the end of the
stud J is fitted a cranked lever V, to which is connected a lever W; this lever is
fitted on a pin X fixed in a bracket Y secured on the top of the rocking slide C.
The rocking slide when actuated by the excentric actuates the lever W, giving a
rocking or oscillating motion to the cranked lever V, imparting a similar rocking or
oscillating motion to the frame K and roller P, which constantly rises and lowers
the belt or apron Q, changing the surface, preventing the formation of grooves
and facets, and producing a great saving in the wear and tear of the belts or
aprons.
Having thus described my improvements, and the best means I am acquainted
with for carrying the same into effect, I would have it understood that I do not confine
myself to the precise details shewn and described, as they may be varied without
departing from the peculiar character of the Invention, but what I do claim is, the

page_text: general arrangement, construction, and employment of the apparatus for constantly
changing the surface of the belt or apron at the part which is presented for the
passage of the wool or fibres when "doffing," or taking the wool or fibres from the
circular comb in the form of a sliver, substantially as herein-before described and
represented by the annexed Drawing.
In witness whereof, I, the said Frederick Henry Wright, have hereunto set my
hand and seal, this Eighteenth day of October, in the year of our Lord One
thousand eight hundred and seventy-seven.
