Improvements in or relating to Carding Engines, Scutchers,
and Openers.
We, ROBERT LORD of Nelson Mills, Cotton Spinner, and GEORGE FLETCHER of
3 Merrick Street, Carder, both of Bolton in the County of Lancaster, do hereby
declare the nature of our said invention to be as follows :-
This invention relates to improvements in the construction of bars forming the
undercasings, grids, or grate-bars employed in carding engines, scutchers, and openers
for preparing cotton and other fibrous materials, and consists in making the same of
tin, zinc, metal, or other suitable materials in a novel manner whereby the upper edge
of each bar is formed in a pointed manner so as to obstruct or arrest the passage of
dirt, seeds, notes, and the like, and at the same time allow the fibres to pass on
through the carding engine, scutcher, or opener. The upper or pointed edge of each
bar is so disposed that it inclines to the centre or thereabouts of the circle described
by the "licker-in," card cylinder, or beater it is applied to work in conjunction there-
with. By thus inclining the upper or pointed edge of each bar they can be fixed
in close and even proximity to the "icker-in," cylinder, or beater. These bars can be
formed in any convenient manner by casting, or by bending or folding thin sheet
metal, or otherwise, and can be secured in position and supported in the usual manner
or otherwise in the various machines to which they are applicable. The lower portion
of each bar is formed at an angle to the pointed edge so as to cause no obstruction to
dirt and other imperfections passing through the openings or spaces between the
same B and is constructed to prevent lodgment on the same.

Improvements in or relating to Carding Engines, Scutchers,
and Openers.
We, ROBERT LORD of Nelson Mills, Cotton Spinner, and GEORGE FLETOHER of
3 Merrick Street, Carder, both of Bolton in the County of Lancastor, 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:-
This invention relates to improvements in the construction of bars forming the
undercasings, grids, or grate-bars employed in carding engines, scutchers, and openers
for preparing cotton and other fibrous materials, and consists in making the same of
tin, zinc, metal, or other suitable materials in a novel manner whereby the upper edge
of each bar is formed in a pointed manner so as to obstruct or arrest the passage of
dirt, seeds, motes, and the like, and at the same time allow the fibres to pass on
through the carding engine, scutcher, or opener. The upper or pointed edge of each
bar is so disposed that it inclines to the centre or thereabouts of the circle described
by the "licker-in," card cylinder, or beater it is applied to work in conjunction there-

dirt and other imperfections passing through the openings or spaces between the
same, and is constructed to prevent lodgement on the same.
Fig. 1 is a part sectional elevation of an andercasing, grid, or grate-bars employed
in carding engines, scutchers, and openers for preparing cotton and other fibrous
materials constructed on our improved principle with the bars of the same formed by
bending or folding thin sheet metal. Fig. 2 is a part sectional elevation of an under-
casing, grid, or grate-bars employed in the aforesaid machines with the bars made
solid, and Fig. 3 is a part plan of Figs. 1 and 2.
A is a circle to represent the outer surface or circumference of a licker-in,"
carding cylinder, or beater our improved undercasing, grid, or grate-bars may be
applied to; B is the side framing of the undercasing or grid with our improved
grate-bars fixed or attached thereto, and M is the plain concaved upper surface of
the undercasing.

Our invention consists in the formation and construction of the grate-bars C of tin,
zinc, metal, or other suitable materials with the upper edge D of each bar C formed
in a pointed manner and inclining to the circle A described by a licker-in," carding
cylinder, or beater employed in the machines previously described, so as to obstruct or
arrest the passage of dirt, seeds, motes, and the like when passing through the
machine in the direction indicated by the arrow, and at the same time allowing the
fibres to pass on through the machine. The bars Care so fixed on the sides B as to
leave the passages E to allow the before mentioned imperfections to drop clear into
the chamber underneath, which passages can be of any convenient width according
to circumstances or requirements. To prevent dirt, seeds, motes, and other imper-
fections passing through the passages E being blown back by an undercurrent of air
from the "licker-in," carding cylinder, and beater of the machine the front bar () is
made. considerably deeper as shown in Figs. 1 and 2. The lower part of each bar (
is formed at an angle to the upper pointed edge D, being made straight to prevent
lodgement on the same. The grate-bars C with their angular ends 1) can be formed
by bending or folding thin sheet metal as shown in Fig. 1, or of solid metal as shown
in Fig. 2, and are attached to the side frames B by soldering or other convenient
means; the whole being supported in the usual manner or otherwise in the various
machines to which they may be applied.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
In undercasings, grids, or grate-bars employed in carding engines, scutchers, and
openers for preparing cotton and other fibrous materials the use and construction of
the bars C provided with-the-inclined _upper_edges D for the purpose specified,
substantially as described.
