CERTAIN IMPROVEMENTS IN CARDING ENGINES
Year: 1859

page_text: LETTERS PATENT to Edward Barlow, of the Firm of Messieurs Dobson
and Barlow, Machine Makers, of Bolton-le-Moors, in the County of
Lancaster, and Francis Hamilton, of the same Place, Manager, for the
PROVISIONAL SPECIFICATION left by the said Edward Barlow and
Francis Hamilton at the Office of the Commissioners of Patents,..with
their Petition, on the 19th November 1859.
We, EDWARD BARLOW, of the Firm of Messieurs Dobson and Barlow,
Machine Makers, of Bolton-le-Moors, in the County of Lancaster, and
FRANCIS HAMILTON, of the same Place, Manager, do hereby declare the
nature of the said Invention for "CERTAIN IMPROVEMENTS IN CARDING ENGINES,"
to be as follows:-
Our Invention is applicable to those carding engines in which top flats are
used, and it consists in the application of adjustable plates or brackets for
supporting the said top flats and for adjusting them to the surface of the main
cylinder. In performing our Invention we cast or attach bosses to the bend
forming part of the framing, and to each boss is fitted a plate, the position of
which can be adjusted laterally by set screws or otherwise; this plate is
furnished with ribs to guide a second plate on which the end of the top flat

page_text: rests, a projection on the said plate entering into a recess in the top flat to
guide the same laterally. The position of the second plate is regulated by a
set screw, and both the plates are secured to the bend by a screw or bolt, or
the top flats may be supported at each end by a single plate fitting on the boss
of the bend on which it can move laterally, and which is acted on by a set 5
screw to regulate the distance between the card teeth of the main cylinder
and the top flat.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Barlow and Francis Hamilton in the Great Seal
Patent Office on the 19th May 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
BARLOW, of the Firm of Messieurs Dobson and Barlow, Machine Makers, of
Bolton-le-Moors, in the County of Lancaster, and FRANCIS HAMILTON, of the
same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of November, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Edward Barlow and Francis Hamilton, Her special licence
that we the said Edward Barlow and Francis Hamilton, our executors,
administrators, and assigns, or such others as we, the said Edward Barlow
and Francis Hamilton, our executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
thereafter 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 IMPROVEMENTS IN CARDING ENGINES," upon the condition (amongst
others) that we, the said Edward Barlow and Francis Hamilton, our execu-
tors or administrators, by an instrument in writing under our or their or one
of our or 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 we, the said Edward Barlow and Francis
Hamilton, do hereby declare the nature of our said Invention, and in

page_text: what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say):-
Our Invention is applicable to those carding engines in which top flats are
used, and it consists in the application of adjustable plates or brackets for
supporting the said top flats and for adjusting them to the surface of the main
cylinder. In performing our Invention we cast or attach bosses to the bend
forming part of the framing, and to each boss is fitted a plate, this plate is
furnished with ribs to guide a second plate on which the end of the top flat
rests, a projection on the said plate entering into a recess in the top flat to
guide the same laterally. The position of the second plate is regulated by a
set screw, and both the plates are secured to the bend by a screw or bolt, or
the top flats may be supported at each end by a single plate fitting on the boss
of the bend, which is acted on by a set screw to regulate the distance between
the card teeth of the main cylinder and the top flat.
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 a side view of part of a carding engine of the ordinary construction
to which our improvements are applied; Fig. 2 is an end view partly in
section; Fig. 3 is a detached view on an enlarged scale of our improvements;
Fig. 4 is a vertical, and Fig. 5 a transverse section of the same; Figs. 6, 7,
and 8, are similar views of a modification of our improvements.
In Figs. 1, 2, and 3, a is part of the main cylinder of the carding engine;
b, b, are parts of the framing commonly called the "bends," shewn best in
Fig. 4; to these bends, in addition to the usual bosses for the workers and
clearers, as shewn in c, c, in Fig. 1, are also cast or fixed as many bosses d,
see Fig. 4, as there are top flats to the carding engine; on each boss d, fits a
plate e, the lower end of which is guided by a rib on the bend b, which rib fits
in a recess in the lower part of the plate e; the plates e are also made with
lateral ribs, shewn in Fig. 5, which serve as guides to the plates f, which have
projections fitting between the said lateral ribs; at the upper end of each
plate f, is the projection g, which takes into a recess in each end of each top
flat h, which bears on chipping pieces on the plate f, both the plates e and f
are secured to the bend by a set screw i, passing through a slot in the plate f,
and tapped into a hole in the boss d. The set of the card teeth is given by
bevelling the lower surface of the top flat, as shewn in Fig. 3, in the usual
manner, and the distance between the card teeth on the top flat and the cards
on the main cylinder is regulated by the set screw j, which is tapped into a
projection on the plate f, and fits between the boss d, and the projection on

page_text: the plate e.
In Figs. 6, 7, and 8, we have shewn how each end of the top
flats may be supported by a single plate k, this plate is made with internal
ribs 1, 1, see Fig. 8, which fit on each side of the bosses d, and the recess m fits
on a rib cast to the bend to guide the plate k. The set screw j, is tapped in
the end of the plate k, and serves to regulate the distance between the top flat
and the main cylinder, as in Figs. 3 and 4, the plate k is also secured to the
bend by a set screw i, as described in reference to the previous Figures. By
means of these improvements the surface of the wire cards on the top flats
can be adjusted expeditiously and accurately to the cards on the main
cylinder.
Having thus stated the nature of our Invention and described the manner
of performing the same, we declare that we claim the improved arrangements
of parts shewn, or any modification thereof, for supporting and adjusting the
top flats of carding engines.
In witness whereof, we the said Edward Barlow and Francis Hamilton,
have hereunto set our hands and seals, this Sixteenth day of May, in
the year of our Lord One thousand eight hundred and sixty.
