Year: 1854

page_text: LETTERS PATENT to William Brown, of Bradford, in the County of York
Mechanic, for the Invention of "IMPROVEMENTS IN PREPARING TO BE SPUN
- WOOL AND OTHER FIBROUS MATERIAL.".
Sealed the 4th July 1854, and dated the 10th January 1854.
PROVISIONAL SPECIFICATION left by the said William Brown at the
Office of the Commissioners of Patents, with his Petition, on the 10th
January 1854.
I, WILLIAM BROWN, of Bradford, in the County of York, Mechanic, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN PRE-
PARING TO BE SPUN WOOL AND OTHER FIBROUS MATERIAL" to be as follows:-
The improvements relate to means for removing the noil, knots, and small
lumps, or other matters rendering the work imperfect, from wool and other
fibrous material.
Thin but broad teeth with pointed ends are placed near together in bars or
rollers, and are actuated so as to be capable of striking in rapid succession
with the points through slivers, slubbings, or rovings. The noil, knots, or
small lumps of unworked wool or other matters mixed with the fibre thus
caught on the points of the teeth are pushed through the sliver, slubbing, or
roving into contact with a surface of card teeth or brushes, rotating or other-
wise moving past so as to take such matters as are pushed through by the flat
pointed teeth.
I

page_text: Such matters as are not taken by the card or brush surface will remain on
the surface of the sliver or roving, and I remove these by passing them through
a series of fine gill teeth, with that side to which the knots have been raised
turned next the bottom of the teeth where I find the knots or other matters
are generally intercepted.
These knots or other matters I propose to remove from the bottom of
the gil teeth by hand or otherwise, after a sufficient quantity has been
accumulated.
The Invention ouplies to all

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said William Brown in the Great Seal Patent Office on the 10th
July 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROWN, of Bradford, in the County of York, Mechanic, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of January, in the year of our Lord One
thousand eight hundred and fifty-four, in the seventeenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said William Brown, Her special licence that I, the said William Brown,
my executors, administrators, and assigns, or such others as I, the said
William Brown, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN PREPARING TO BE SPUN WOOL AND OTHER FIBROUS MATERIAL," upon the
condition (amongst others) that I, the said William Brown, by an instrument
in writing under my hand and seal, should particularly describe and ascer
tain 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.
NOW KNOW YE, that I, the said William Brown, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof (that is to say):-

page_text: The improvements relate to means for removing the noil, knots, and small
lumps or other matters from wool and other fibrous material, and they consist
in the employment for this purpose of thin but broad teeth with pointed ends,
placed near together in bars or cylinders, and so as to be capable of being
actuated in order that the points of the teeth may strike in rapid succession
through slivers, slubbings, or rovings of wool and other fibrous material brought
into position to be acted upon by the points of the teeth. But that the nature
of the said Invention, and the means by which I carry the same into effect,
may be fully understood, I will proceed to describe the Drawing annexed.
DESCRIPTION OF THE DRAWING.
I would here state that I have not thought it necessary to do more than
show a diagram of one means which I have found to answer in carrying my
Invention into practice, as a workman acquainted with the class of machines
to which I have adapted my improvements will readily make such modifications
as he may think desirable when otherwise applying my improvements. a, a,
are the thin flat teeth, having pointed ends a², for perforating the wool or other
fibrous material. These plates a are shewn applied to gill bars b, capable of
following each other in the direction of the arrow, and thereby striking into
the fibre in succession, as is well understood in working ordinary gill bars,
but the bars of teeth may be applied to a cylinder, if desired, arranged and
actuated so that the points of the teeth may be capable of striking in rapid
succession through the slivers, slubbings, or rovings. The length and width, as
well as the form and number of the teeth, as also the amount of motion given
to them, may however be varied.
At Figure 2 I have shewn a variation of the form of teeth or blades by the
point a being produced on one side thereof, leaving a shoulder a² to retain
the short fibres, knots, and other matters, and prevent them rising and again
mixing with the longer fibres; and at Figure 3 I have shown other forms
of blades or teeth, more particularly adapted to be applied to a cylinder or
roller.
The fibre is fed into position by the rollers c, c, and drawn off by means of
the rollers d, d. By the rapid movement of the blades or teeth a through the
fibre, the noil, knots, or small lumps of unworked wool or other matters mixed
with the fibre will be caught on the points of the teeth and pushed through
the sliver, slubbing, or roving into contact with a surface of card teeth or
brushes, rotating or otherwise moving past and in contact with the points a¹, so
as to take the matters pushed through by those points. e is a rotating brush
surface, which I have found to answer to clear the points of the teeth a; but

page_text: this may be varied in form and mode of working. And although I have shewn
the points of the blades a to move in a direction downwards when passing
through the fibre, for the purpose of extracting the knots and other matters,
a like effect may be obtained by their direction of motion at such time being
in an upward or other direction.
Such matters as are not taken by the card or brush surface will remain on
the surface of the sliver or roving, and I remove these by passing the sliver
through a series of fine gill teeth, with that side of it to which the knots or
other matters have been raised turned next the bottom of the teeth, where I
find the knots or other matters are generally intercepted.
These knots or other matters I propose to remove from the bottom of the
gill teeth by hand or otherwise, after a sufficient quantity has been accumu-
lated. I prefer that the gill teeth thus employed have not less than thirty-six
teeth to the lineal inch.
I also prefer that the parts be so arranged that the surface speed of the
teeth a exceeds that of the feed rollers, and that the surface speed of the
drawing off rollers exceeds that of the bars of blades or teeth.
Having thus described the nature of my said Invention, I would have it
understood that I do not confine myself to the precise details herein shewn and
described, so long as the peculiar character of my Invention be retained. But
what I claim is, the application of thin but comparatively broad teeth or
blades with pointed ends, actuated so as to be capable of striking in rapid
succession through slivers, slubbings, or rovings of wool or other fibrous
material, for the purpose of removing noil, knots, and small lumps or other
matters therefrom, as herein explained.
In witness whereof, I, the said William Brown, have hereunto set my
hand and seal, this 8th day of July, in the year of our Lord One
thousand eight hundred and fifty-four.
