PROVISIONAL SPECIFICATION.
Improvements in Carding Engines.
I HENRY ISITT of 105 Milnrow Road Rochdale in the County of Lancaster Engineer
do hereby declare the nature of this invention to be as follows:-
"
This invention relates to improvements in the construction of carding engines
employed in carding cotton, the object of the invention being to obtain upon a single
cylinder engine the combined effect of a "breaker," an intermediate" and a
finisher," thereby producing the most perfect and tiue carding by the use of a single
cylinder engine at one operation.
The invention consists principally in the combination in one single cylinder carding
engine of "rollers and clearers," Wellmans or other similar uplifting or self-stripping
"flats" and "revolving flats."
I construct my improved carding engine with one main cylinder (say for example)
of about fifty inches diameter.
The breaker section consists of a metallic covered "licker-in" and a single roller
and clearer (or two rollers and clearers) clothed with moderately coarse card wire in
order to impart to the cotton a preliminary breaking or opening up.
2
The intermediate" section consists of a short series of "flats" on the "Wellman"
or other uplifting and self stripping principle clothed somewhat finer than the
"breaker" section.
The finisher" section consists of a short series of "revolving flats" clothed
with still finer wire by which the cotton is finally combed before reaching the
doffer.
As a modification, in some cases especially for fine staple cotton, 1 propose to
dispense with the rollers, and clearers, and to use only "flats" on the "Wellman "
or other uplifting and self-stripping principle in combination with the revolving
"Alats."
This improved arrangement permits of the graduation of the card clothing (which
is an impossibility on the present engines with revolving "flats") whereby the cotton
is progressively carded and a better result obtained..

COMPLETE SPECIFICATION.
Improvements in Carding Engines.
I HENRY ISITT of 105 Milnrow Road, Rochdale in the County of Lancaster Engineer
do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in the construction of carding engines
employed for carding cotton the object of the invention being to obtain upon a single
cylinder engine the combined effect of a "breaker" an "intermediate," and a
"finisher" thereby producing the most perfect and true carding by the use of a single
cylinder enginejat one operation.
The invention consists principally in the combination on one single cylinder carding
engine of "rollers and clearers " Wellman's " or other similar uplifting or self
stripping flats" and "revolving flats."

page_text: And my invention will be readily understood on reference to the accompanying
drawing which represents in elevation so much of a carding engine (constructed
according to my invention) as is necessary to illustrate the same.
I construct my improved carding engine with one main cylinder (say) for example
of about fifty inches diameter represented by the dotted circle a.
The "breaker" section consists of a metallic-covered "licker-in" b and a single
roller c and clearer d (or more than one roller and clearer) clothed with moderately
coarse card wire in order to impart to the cotton a preliminary breaking or
opening up.
The intermediate "section" shewn at e consists of a short series of "flats" on the
"Wellman," or other uplifting and self-stripping principle preferably clothed somewhat
finer than the "breaker" section.
If desired the Wellman flats may he graduated i.e., the first flats for example may be
clothed with coarser wire than those which are behind them.
The "finisher" section shown at consists of a short series of “revolving flats"
preferably clothed with still finer wire by which the cotton is finally combed before
reaching the "doffer " g.
As a modification in some cases especially for fine staple cotton I propose to
dispense with the roller and clearer or rollers and clearers and to use only flats on the
"Wellman" or other uplifting and self stripping principle in combination with the
revolving flats.
These improved arrangements permit of the graduation (as above described) of the
card clothing (which is an impossibility on the present engines with revolving "flats")
whereby the cotton is progressively carded and a better result obtained.
My improvements will also obviate the choking up of the flats near the doffer end
which takes place on the ordinary revolving flat card.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
First. The combination on a single cylinder carding engine of uplifting self-
stripping flats (such as those commonly known as "Wellman's") with those generally
known as revolving flats and either with or without a roller and clearer or rollers and
clearers substantially as hereinbefore described and illustrated by the accompanying
drawing.
Secondly. The combination on a single cylinder carding engine of uplifting self-
stripping flats (such as those commonly known as "Wellman's ") with those generally
known as revolving flats, either with or without a roller and clearer or rollers and
clearers the clothing or counts of wire being graduated substantially as herein before
described.
