Year: 1861

page_text: LETTERS PATENT to William Whalley, Engineer, of Granges, in the
.Department of the Vosges, in the Empire of France, at present residing
in the City of Manchester, for the Invention of "CERTAIN IMPROVEMENTS
IN MACHINERY FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said William Whalley at the
Office of the Commissioners of Patents, with his Petition, on the 27th
February 1861.
I, WILLIAM WHALLEY, Engineer, of Granges, in the Department of the
Vosges, in the Empire of France, at present residing in the City of Manchester,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVE.
MENTS IN MACHINERY FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES," to
be as follows:
My invention is applicable to those carding engines in which working and
clearing rollers are employed, and it consists in applying a knife or blade of
metal or other material between the said working and clearing rollers, to
regulate the passage of the fibrous substances, and to hold them while the
working rollers comb out the fibres and separate them from the leaf and other
foreign matters, which are caught by the stripping rollers and deposited into
[Price 8d.]

page_text: a suitable receptacle. In this receptacle is a revolving rod or shaft which
takes up all the useless short fibres with the leaf and other foreign matters,
and forms them into a lap which is removed at intervals.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Whalley in the Great Seal Patent Office on the
26th August 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WHALLEY, Engineer, of Granges, in the Department of the Vosges, in the
Empire of France, at present residing in the City of Manchester, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of February, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Whalley, Her special licence that I, the said William Whalley,
my executors, administrators, and assigns, or such others as I, the said
William Whalley, 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 "CERTAIN IMPROVE
MENTS IN MACHINERY FOR CARDING COTTON AND OTHER FIBROUS SUBSTANCES," upon
the condition (amongst others) that I, the said William Whalley, my
executors or administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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 Whalley, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement (that is to say):-
The nature of my Invention consists in a certain improved arrangement or
parts applicable to those carding engines in which the cotton or other fibrous
*substance is carded in passing between the main cylinder and working rollers,

page_text: the surfaces of which are stripped by clearing rollers, the object of my Invèn-
tion being to increase the carding or combing action of the working rollers,to
collect the flyings of fibrous substances with the loose impurities in the form
of a lap, and to deposit the sand or heavy dirt and impurities in a receptacle
or box.
And in order that my Invention may be fully understood and readily carried
into operation, I will proceed to describe the accompanying Sheet of Drawings,
reference being had to the Figures and letters marked thereon.
Figure 1 is a longitudinal section of part of a carding engine to which my
improvements are applied. a is the main cylinder; b, the working rollers, and
C, the clearing rollers or strippers; these parts, and the others which are not
shewn in the Drawing, and not particularly referred to hereafter, but, which are
requisite to completethecarding engine,aremadein theusualmanner. Between
each pair of working and clearing rollers, or between any one or more of such
pairs is a blade of steel or other metal or material marked d, supported at each
end on adjustable bearings connected to the bends of the carding engine, and
between each pair of working and clearing rollers, or between any one or more
of them, is a box or receptacle e, shewn detached in Figures 2 and 3, and
supported at each end by the projection e! fitting in a slot in the bends, the edge
of the receptacle being set close to the surface of the stripping roller. Within
each receptacle 6 is a square or other shaped rod f; to which a slow rotary
motion is given by a chain or band passing over a pulley on the end of the axle
of one of the working rollers, and over a pulley on the end of each rod f, as
shewn in Figure 4. The working rollers b,clearing rollers c,and rods f,revolve
in the directions indicated by the arrows in Figure 1.
:
The mode of operation is as follows:-The fibres carried forward by the
main cylinder from the licker in are carded in the usual manner between the
main cylinder.and the first of the working rollers 6; they then proceed to the
second working roller, and the fibres caught by the card teeth of this roller,
together with the motes and other impurities, are carried round until they pass
the edge of the blade d, when the stripping rollerc, which revolves considerably
faster than the working roller b, strips the fibres, with the motes and other
impurities,off the roller b, and they are thrown or deposited into the receptacle e
(the edge of which is set near to the teeth of the clearing roller), and are
then either collected in the form of a lap on the revolving bar f, or drop down
into the bottom of the receptacle. A similar operation is performed by all
the working and stripping rollers, consequently the fleece of fibrous materials
deposited on the doffer by the main cylinder is effectually carded and free
from motes and other impurities.

page_text: In the Drawing above described I have shewn my improvements applied to
four pairs of working and clearing rollers, because I have found by experience
that by this arrangement a good result is produced; I wish, however, to remark
that I do not intend to limit myself to these details, as the number of working
and clearing rollers to which the blades and receptacles are applied may be
increased or diminished, or their position varied according to the particular
construction of the carding engine to which these improvements are applied,
and to the quality of the work to be produced. In the preceding description,
and in the Figures referred to, I have supposed the rollers between which the
receptacles are introduced, to be placed at greater distances from each other
than usual, to admit receptacles of what I consider the most convenient form
but in Figure 5, I have represented part of a carding engine shewing the
modeofapplying my Invention to carding engines of the ordinary construction,
as regards the situation of the rollers, and in which the working and clearing
rollers being nearer together than in Figure 1, the form of the receptacle é is
altered accordingly.
Having thus stated the nature of my Invention, and described the manner
of performing the same, I wish it be understood that I make no claim to
either the blades d'or receptacles e, separately or otherwise than in such
arrangement and combination as aforesaid, as I am aware that bars or straight
edges have before been applied between the working and clearing rollers and
that receptacles, either with or without bars or straight edges attached thereto,
have been placed over the surface of the main cylinder, but I declare that I
claim as of my Invention,-
First, the application and use for the purpose herein-before mentioned of the
revolving bar f.
And, secondly, the arrangement and combined application of the blades d
and receptacles e in connexion with the working and clearing rollers of carding
machines, in the manner and for the purposes herein-before described.
In witness whereof, I, the said William Whalley,have hereunto set my
hand and seal, this Twenty-fourth day of August, in the, year of ou
Lord One thousand eight hundred and sixty-one
WILLIAM WHALLEY. (L.S.)
