I SAMUEL WALKEY GILLETT of H. B. Barlow's Office for Patents, 17, St Ann's
Square Manchester in the County of Lancaster Managing Clerk, do hereby declaré
the nature of said Invention for AN IMPROVED TOOTHED GRID FOR OPENERS,
SCUTCHERS, BLOWERS, AND OTHER MACHINES FOR PREPARING COTTON, WOOL, AND
OTHER TEXTILE FIBRE, which invention has been communicated to me from abroad
by Messieurs Michel Descards et la Société Flecheux père et fils et Jantot, of Rouen
in the Republic of France, Engineers to be as follows:-
This invention consists in the construction of a new system of toothed grids,
and in the application of the same to the working surfaces of openers, scutchers,
beaters, blowers, and other machines for preparing cotton and other textile fibrc.
The improved grid is formed of a series of toothed blades or strips connected
together by tio pieces, which when united form an open-work plate: the tie pieces
keep the blades or strips in position and insure stability and rigidity. If desired
the open-work plate may be cast in one piece.
The whole grating of the opener or other machine will be formed of these open-
work toothed plates. These plates may be used not only in place of the ordinary
grids, but generally for the working surfaces of the machines, for cylinders of any
diameter and in either vertical or horizontal machines.
By the use of these improved plates the fibre is more thoroughly opened and
cleaned, and it is less injured than by machines of the ordinary construction.

Square, Manchester in the County of Lancaster, Managing Clerk, do hereby declare
the nature of said Invention for AN IMPROVED TOOTHED GRID FOR OPENERS,
SCUTCHERS, BLOWERS, AND OTHER MACHINES FOR PREPARING COTTON, WOOL AND
OTHER TEXTILE FIBRE, a communication to me from abroad by Messieurs Michel
Descards et la Société Flecheux père et fils et Jantot, of Rouen, in the Republic
of France, Engineers, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention consists in the construction of a new system of toothed grids and
in the application of the same to the working surfaces of openers, scutchers,
beaters, blowers, and other machines for preparing cotton and other textile fibre.
The improved grid is formed of a series of toothed plates or strips connected
together by tio-pieces which when united form an open work plate: the tie-pieces
keep the blades or strips in position and insure stability and rigidity. If desired,
the open work plate may be cast in one piece. The whole grating of the opener
or other machine will be formed of these open work toothed plates.
These plates may be used not only in place of the ordinary grids, but generally
for the working surfaces of the machines, for cylinders of any diameter, and in
either vertical or horizontal machines.
By the use of these improved plates the fibre is more thoroughly opened and
cleaned and it is less injured than by machines of the ordinary construction.
And in order that this Invention as communicated to me by my foreign
correspondents may be fully understood and readily carried into effect I will
proceed to describe the accompanying Sheet of Drawings, reference being had to
the figures and letters marked thereon.
Figure 1 is a plan looking downward and Fig. 2 a plan, looking upward, of an
improved toothed grid constructed according to this Invention. Fig. 3 is a transverse
section on the line CD and Fig. 4, a longitudinal section on the lino E F. Fig. 1.
These drawings represent an improved grid made in one casting.
A is the base plate or foundation in which are formed the holes B which taper
from a large opening on the lower side to a smaller opening on the upper side: the
openings B shown are elliptical in form and are arranged longitudinally in parallel
lines in such manner that the openings in one line overlap those in the next. The
upper surface of the grid is made with a series of toothed blades or strips, the
teeth C of which come opposite the openings B: the shape of the blades or strips
and the angle at which the metal is cut away from the edge of the teeth C to the
bottom of the opening B is clearly shown in Fig. 3.
This construction and arrangement of toothed blades and openings forms a
simple strong and effective toothed grid which may be used not only in place of
the ordinary grids but generally for the working surfaces in openers, scutchers,
beaters, blowers and other machines for preparing cotton, wool, and other textile
fibre.
The invention may also be applied to the cylinders of such machines by casting
the open work toothed plates in sections of any convenient size and either flat or
concave at the back or base and fixing them as beaters upon a skeleton cylinder.
The improved toothed grids and the improved cylinders may be used in com-
bination or either of them separately and in place of making the open work
toothed plates in one casting they may be built up or formed in any convenient
manner.

page_text: Having now particularly described. and ascertained the nature of the said.
Invention and in what manner the same is to be performed.
1 declare that what I claim is―
The construction, use, and application of open work toothed plates for the grids,
cylinders or other working surfaces of openers, scutchers, beaters, blowers, and
other analogous machinery, substantially in the manner and for the purposes
herein set forth.
