Year: 1869

page_text: LETTERS PATENT to William Richardson, of Oldham, in the County
of Lancaster, Mechanical Engineer, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR BURRING OR CLEANING WOOL, COTTON, AND OTHER
FIBROUS MATERIALS."
Sealed the 1st April 1870, and dated the 5th October 1869.
PROVISIONAL SPECIFICATION left by the said William Richardson
at the Office of the Commissioners of Patents, with his Petition,
on the 5th October 1869.
I, WILLIAM RICHARDSON, of Oldham, in the County of Lancaster,
Mechanical Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY FOR BURRING OR CLEANING WOOL, COTTON, AND
OTHER FIBROUS MATERIALS," to be as follows:-
My Invention relates to that description of burring or cleaning
machinery in which what is commonly called a fine comb cylinder is
employed, and consists in the use of two or more of such cylinders in
one machine.
The arrangement I propose is to deliver the material to the first
cylinder by the usual beater and chargers, and from this the impurities.

page_text: and tangled masses are taken off by a guard roller and delivered to a
charger or chargers, which place them upon the second fine comb
cylinder, from which the burrs are removed as in the former instance.
These burrs may be disposed of in any ordinary manner; but I propose
to employ a grid and the transferring apparatus for which Letters
Patent were granted to me, dated 30th September 1868, No. 2995, and to
employ it to carry back the said burrs to the charger of the second
cylinder. I propose to strip the material from the two comb cylinders
by means of one brush running in contact with both of them.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Richardson in the Great Seal Patent
Office on the 5th April 1870.
TO. ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RICHARDSON, of Oldham, in the County of Lancaster, Mechanical
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of October, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Richardson, Her special
license that I, the said William Richardson, my executors, adminis-
trators, and assigns, or such others as I, the said William Richardson,
my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN MACHINERY FOR BURRING OR CLEANING WOOL, COTTON, AND OTHER FIBROUS
MATERIALS," upon the condition (amongst others) that I, the said
William Richardson, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said
Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.

page_text: NOW KNOW YE, that I, 'the said William Richardson, do hereby
declare the nature of my said Invention, and in what the same is to be
performed, to be particularly described and ascertained in and by the
following statement (and accompanying Drawings), that is to say:-—
My Invention relates to that description of burring or cleaning
machinery in which what is commonly called a fine comb cylinder is
employed, and consists in the use of two or more of such cylinders in
one machine.
The arrangement I propose is to deliver the material to the first
cylinder by the usual beater and chargers, and from this the impurities
and tangled masses are taken off by a guard roller and delivered to a
charger or chargers, which place them upon the second fine comb
cylinder, from which the burrs are removed as in the former instance.
These burrs may be disposed of in any ordinary manner; but I propose
to employ a grid and the transferring apparatus for which Letters
Patent were granted to me, dated Thirtieth September One thousand
eight hundred and sixty-eight, Number 2995, and to employ it to carry
back the said burrs and fibrous material to the charger of the second
cylinder.
The accompanying Drawing shews a burring machine of the aforesaid
description, and the operation of the working parts of which is described
in the Specification of the Patent granted to me as aforesaid. I will
however now repeat the arrangement of the machine in order to connect
clearly my present Invention therewith.
The feed apron upon which the material is placed is shewn at b
carried by the frame a; this apron by its travelling motion delivers
the fibrous material to the spiked feed roller d and dish c, by which it
is transferred, to the beater blades f mounted upon the cylinder c, and
the separated dirt falls through a grid g. At h is what is commonly
called the fine comb cylinder provided with combs k. Beneath this
cylinder is a roller 1, in which is fixed a parallel series of notched
blades m extending around its circumference, and at n is another
similar roller, beyond which is a rotatory brush o. The cylinder / is
provided with a casing p, an extension of which encloses a revolving
disc 9, which carries cross bars furnished with brushes & revolving in
contact with the combs &, and at w is the revolving guard roller, which
removes the burrs and other impurities together with a certain portion

page_text: of fibrous material. So far the machine is the same as that described in
my former Patent aforesaid, and in which I described an improved
apparatus for restoring the rejected material to the combs k; but
according to my present Invention the said rejected material is not
returned to the combs k, but is placed upon another fine comb cylinder,
the arrangement for which is as follows:-Beyond the roller w and
running clear of it is a second fine comb cylinder h², in connexion with
which there are charging rollers l', n', and brush o', and corresponding to
the roller w is a second roller w². The roller to discharges the removed
'portion's upon the roller 7, which is enclosed in a casings, and they are
carried upward by the said roller A, and fed to the cylinder ', the other
roller n¹ and brush o' performing the same operations as the first
set 1, n, o, as fully described in the Specification of my former Patent
aforesaid. After the combs ¹ have passed the brush o' they meet with
the revolving roller w³, which strips the remaining burrs, &c., casting
them down as I will now assume into any convenient receptacle. The
combs charged with cleaned material passing onward meet with the
rotating brushes 8, which being placed midway between the two
cylinders act as a stripper for both, and the said material is passed on
to the cages and is delivered by the rollers u and apron v, or the said
cages may be dispensed with and the material delivered in any desired
usual manner.
I have hitherto supposed that the rejected material removed by the
roller w¹ has been cast thereby into any convenient receptacle, and my
improved arrangement of a second fine comb cylinder may be so a
employed; but I prefer delivering it to a transferring apparatus, by
means of which it is restored to the said second cylinder.
The arrangement I employ for this purpose is the same as that which
formed the subject of my previous Patent aforesaid, the grid therein
described being at x, and the rising and falling and travelling spikes
at y; when therefore the rejected material is removed by the roller w' it
is thrown upon the grid x, and that portion which does not pass through
the said grid is conveyed forward and delivered to the roller A, which
carries it up the shield z, and deliver it to the second fine comb
cylinder h¹, where it again undergoes the operation above alluded to. 2
It will be perceived by this arrangement that no rejected material is
returned to the first fine comb cylinder, the combs of which are simply
charged by the incoming material.

page_text: Having thus described and ascertained the nature of my said Invention,
and the manner in which the same is to be performed, I desire it to be
understood that although I have only shewn and described two fine
comb cylinders, three or more may be employed if desired after the
manner above explained, the material passing successively through the
series; that which I claim as secured to me under the above in part
recited Letters Patent being,-
Firstly. The use of two or more fine comb cylinders in one machine.
Secondly. The employment of a revolving brush, as illustrated at 8,
for stripping two of such cylinders.
In witness whereof, I, the said William Richardson, have hereunto
set my hand and seal, this Fourth day of April, in the year of
our Lord One thousand eight hundred and seventy.
