NOW KNOW YE, that we, the said William Henry Oates and Richard
Jones, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement and accompanying
Drawings,

Our Invention relates to the carding engines employed in the pre-
paration of cotton and other fibrous materials; and consists in the first
place of the application of an additional card roller below the: doffing
roller, the said additional roller working in connexion with the main
cylinder and also with the said doffing roller solas to strip they said
main cylinder of the fibres left thereon by the said dóffing roller oriofa
portion of the said fibres," and to deliver theisaid fibres to the said doffing
roller. .

A second part of our Invention consists in the employment of a
second additional roller, which works in connexion with the said doffing
roller, and acts to straighten the fibres upon the said doffing roller, the
effect being that the sliver is more entirely or more cleanly stripped
from off the said doffing roller by the action of the ordinary "doffing
comb:"

And in order that our..Invention may be fully understood, we have
furnished a Sheet of Drawings to accompany this Specification, the said
Drawings being made about one-eighth of the full size, and illustrating
the method of application of our said Invention to a carding engine: "
In the said Drawings Figure 1 represents a sectional side elevation of
the doffing or delivery end of a carding engine, and Figure 2, a side
elevation of the same part of the said carding engine, the parts not
necessary to the illustration of our said Invention not being represented
in the said Drawings.

In Figure 1 a'represents a portion of the main cylinder; b, the doffer
or doffing roller; c, the ordinary doffing comb; and d, the framing of the
engine. The roller, the application of which forms the first part of our
Invention, is represented by e. The axles of the said roller are fitted to
revolve in suitable bearings, and the said roller is so adjusted in position
with reference to the main cylinder a and the doffing roller b as to be in
ordinary working connexion both with the said cylinder and the said
doffing roller; the surface of the roller e being covered with suitable
cards. The said roller is caused to revolve in the direction of the arrow
or is by preference fitted, arranged, and caused to be driven in the said
direction, and acts in connection with the main cylinder a and the doffing
roller 6 in the manner herein-before described. A second roller, applied
to work in connexion with the said roller e and with the doffing roller 6,
is represented by f. The said roller is covered with ".cards" and the
axles of the said roller are mounted in suitable, bearings so, as that the
said roller may be caused to revolve in the direction, indicated, by the
arrow, and to act in the manner herein before mentioned. Two or more
such rollers, may be employed to work in connexion with the doffing
roller bif thought to be 'desirable, but we have not considered it to be
necessary to shew more than one roller in addition to the roller e..
We would here remark that we do not consider the use of the roller f
or of two or more such rollers in the manner herein indicated to be of so
much advantage and importance as the use of the roller e, and that the
last-named roller may be used without employing the said roller f.
•
"
In Figure 2 is indicated a-method of actuating the roller e and also the
roller when the -last-named-roller is employed. A pulley 9 fixed on
one of the axles of the main cylinder gives motion by means of a strap,
chain, or band h to a pulley i, which is fixed on one of the axles of the
-roller e, the said roller being thus actuated. The roller fireceives
motion from the roller e in the manner. indicated in the Drawing We
do not however confine ourselves to this method of actuating-the-said
-roller or rollers, as any other suitable: method may be employed as

page_text: First. The employment of the roller e substantially as and for the
purpose herein-before set forth and indicated.
And, lastly. The employment in connexion with the roller e of the
roller f, or of two or more rollers similar thereto, substantially as and for
the purpose herein-before set forth and indicated.
In witness whereof, we, the said William Henry Oates and Richard
Jones, have hereunto set our hands and seals, this Eleventh day
of June, in the year of our Lord One thousand eight hundred and
seventy-two.
