Tution of 6 NOD-
PROVISIONAL SPECIFICATION left by the said Thomas Sidebottom
Adshead and John Platt at the Office of the Commissioners of Patents,
with their Petition, on the 16th September 1857.
We, THOMAS SIDEBOTTOM ADSHEAD, of Stalybridge, in the County of
Chester, Cotton Spinner, and JOHN PLATT, of Oldham, in the County of Lan-
caster, Mechanical Engineer, do hereby declare the nature of the said Inven-
tion for "CERTAIN IMPROVEMENTS IN MACHINERY FOR CARDING COTTON AND OTHER
FIBROUS MATERIALS," to be as follows:-
Our Invention consists in the application of a vibrating comb or card for
stripping or clearing the surface of a working roller; the comb or card acts
upon the surface of the working roller in such a position that the strippings
are collected on the working roller in the form of a coil.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Sidebottom Adshead and John Platt, in the Great
Seal Patent Office on the 13th March 1858.

page_text: Spinner, and JOHN PLATT, of Oldham, in the County of Lancaster, Mecha-
nical Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of September, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Thomas Sidebottom Adshead and John Platt, Her special licence
that we, the said Thomas Sidebottom Adshead and John Platt, our executors,
administrators, and assigns, or such others as we, the said Thomas Sidebottom
Adshead and John Platt, our 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 MATERIALS," upon
the condition (amongst others). that we, the said Thomas Sidebottom Adshead
and John Platt, our executors or administrators, by an instrument in writing
under our or their, or one of our or their, bands and seals, 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.
NOW KNOW YE, that we, the said Thomas Sidebottom Adshead and John
Platt, 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 (that is to say) :-
'
The nature of our said Invention of certain improvements in machinery for
carding cotton and other fibrous materials consists in an improved mode of
applying a vibrating comb or card to a working roller to strip or clear the
surface thereof, whereby the strippings are collected on the working roller in
the form of a coil.
And in order that our Invention may be fully understood and readily
carried into effect, we will proceed to describe the accompanying Sheet of
Drawings, reference being had to the figures and letters marked thereon.
Fig. 1 is an elevation of part of a carding engine of the usual construction,
to which our improvements are applied. a is the feed roller, b the licker in,
c the main cylinder, d, one of the ordinary stripping rollers, and e one of the
ordinary working rollers; f is a working roller to which our improvements
are applied. The comb or card g by which the roller f is cleared or stripped,

page_text: is supported between brackets h, fixed to the levers i, keyed on a cross shaft j;
this cross shaft and the comb or card have a vibrating motion imparted to
them by the pinion k on the axle of the main cylinder, geering in the wheel l;
from this wheel projects the stud m, to which is hooked one end of the link n,
the other being jointed to the lever o, which is fixed to the cross shaft j, by
this means the requisite vibrating motion is given to the comb or card g for
stripping the roller f; the strippings accumulate on the surface of the roller
in the form of a coil as shewn in the Drawing. We wish to remark that any
other suitable combination of machinery may be employed to give the vibrating
motion to the comb or card.
Fig. 2, represents a modification of our improvements. In this view the
comb or card g is applied to the working roller f, placed immediately above
the licker-in, and a guard p, is placed between the stripper d and the roller f,
to prevent the impurities from the stripper falling on the said roller f. The
machinery for giving the vibrating motion to the comb or card is not shewn
in Fig. 2, as it may be similar to that shewn in Fig. 1, or of any other suitable
construction.
Having thus stated the nature of our Invention, and described two modes
of performing the same, we wish it to be understood that we do not bind
ourselves to the details set forth, as the working roller to which the vibrating
comb or card is applied, may be placed in any other convenient position, and
the mechanism for imparting the vibrating motion may be varied. We would
also observe, that we do not claim any of the parts above referred to when
taken separately; but what we claim is, the application of a vibrating comb
or card to a single working roller in such manner that the strippings are
collected on the surface of the roller in the form of a coil as described.
In witness whereof, we, the said Thomas Sidebottom Adshead and John
Platt, have hereunto set our hands and seals, this Twelfth day of
March, in the year of our Lord One thousand eight hundred and
fifty-eight.
Witness,
H. B. BARLOW,
