SPECIFICATION in pursuance of the conditions of the Letters Patent, filed,
by the said Levi Lumb and William Heap Butterworth in the Great
Seal Patent Office on the 21st November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, LEVT
LUME, of Brotherod Mills, near Rochdale, in the County of Lancaster, Cotton

page_text: Spinner, and WILLIAM HEAP BUTTERWORTH, of Reed Hill, Rochdale, in the
County of Lancaster, Tin Plate Worker, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of May, 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
us, the said Levi Lumb and William Heap Butterworth, Her special license
that we, the said Levi Lumb and William Heap Butterworth, our executors,
administrators, and assigns, or such others as we, the said Levi Lumb and
William Heap Butterworth, our executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times there-
after and 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 UNDERCOVERS OP-CARDING ENGINES," upon the condition (amongst
others) that we, the said Levi Lumb and William Heap Butterworth, our
executors or administrators, by an instrument in writing under our, or their,
or one of our or their hands and seals, should particularly describe and ascer-
tain the nature of the said Invention, and in what manner the same is
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 Levi Lumb and William Heap
Butterworth, 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
(that is to say):-
The nature of our Invention consists in making the under covers of carding
engines entirely or partially of the material known as perforated zinc or other
material perforated in like manner, or of blow work or wire gauze.
And in order that our Invention may be fully understood and easily carried
into effect, we will proceed to describe the accompanying Drawing.
Fig. 1 represents a carding engine of the usual construction, with one of
our improved undercovers applied thereto. a, a, are the feed rollers, which
take the fibrous material that has to be operated upon, and give it to the
taker-in b, which delivers it to the cylinder c, from which, after being carded,
it is taken by the doffer d, from which it is doffed in the usual way. The
undercover e is made the whole width of the cylinder, is supported by the
brackets g, which are fast to the under cover, and which are supported by the

page_text: brackets g', which are bolted to the engine side. The rod h keeps the part of
the undercover that is under the taker-in up to its proper place; it can be
raised or lowered by the nuts h¹.
The parts above enumerated may be made in any approved manner, our
Invention having reference only to making the undercovers of the material
known as perforated zinc or other material perforated in like manner, or of
blow work or zinc gauze. The undercover is shown made of perforated
material.
Fig. 2 shows the full size of the perforations in that part of the cover that
is under the taker-in, and Fig. 3, the size of the perforations in the part under
the cylinder; these sizes of perforations do very well, but we do not limit
ourselves to these sizes or shape of perforations. In place of making the
undercover of perforated material, as shown, it might be inade of blow work
or wire gauze. By these means the sand motes, dirt, and short fibres are
allowed to drop out almost the same as if there was no cover under the
cylinder and taker-in, but the perforations or meshes are small enough to keep
in the good material.
Having thus described the nature of our Invention, and the manner of per-
forming the same, we wish it to be understood that we claim as our Invention,
making the undercovers of carding engines entirely or partially of the
material known as perforated zinc or other material perforated in like manner,
of blow work or wire gauze, for the purposes and as herein-before described.
In witness whereof, we, the said Levi Lumb and William Heap But-
terworth, have hereunto set our hands and seals, this Twentieth day
of November, in the year of our Lord One thousand eight hundred
and sixty-one.
Witness,
