able material and be made of any suitable thickness and may be placed longitudinally
transversely or diagonally and horizontally or in any suitable inclined position in
the scutchers " or lap machines" in which they are to be employed but I
prefer that the said bars or plates should be made of such material and of such
thickness that they are capable of being caused to vibrate by the working of the
machine in which they are to be employed.

COMPLETE SPECIFICATION.
Improvements in the Grids or Gratings Employed and Placed Between
the "Beaters" and "Cages" in the Machines known as "Scutchers
"
or "Lap Machines," and used in the "Preparation" of Cotton and
other Fibrous Materials.
I, WILLIAM HURST, of Hamer Hall, Rochdale in the County of Lancaster 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 —
"
My invention relates to the grids or gratings employed and placed between the
"beaters
"6
and cages
in the machines known as "scutchers or jap
machines and used in the "preparation" of cotton and other fibrous materials
and consists in means by which I am enabled to increase the efficiency of such
machines in separating "motes," leaf and other refuse from the cotton or other
fibrous material being operated upon and by which cause the "motes," leaf or
other refuse separated from such cotton or other fibrous material and deposited
between the bars or plates employed in the said grids or gratings to be held or
retained by such grids or gratings.
دو
According to one mode of accomplishing the object of my invention I form in
or through each of the bars or plates of which the gratings or grids employed in
"scutchers or "lap machines consist a notch, perforation, opening, slit, or slot,
or notches perforations, openings, slits or slots, or any combination of any of such
devices of any suitable shape and size, formed in any suitable position in the bar
or plate and in any suitable position whether vertical, inclined or horizontal.
Bars or plates formed according to this mode of accomplishing the object of
my invention are illustrated in Figs. 1, 2, 3, 4, 5, 6 and 7 of the accompanying
drawings.
Fig. illustrates a bar or plate formed with a notch (a).
Figs. 2 and 3 illustrate bars or plates formed with several notches (a).
Fig. 4 illustrates a bar or plate formed with perforations (b).
Fig. 5 illustrates a bar or plate formed with a slot (c).
Fig. 6 illustrates a bar or plate formed with inclined slots (c. c) and
Fig. 7 illustrates a bar or plate formed with a hole (d).
The notch or notches, perforations, slot or slots, or holes formed in the bars or
plates illustrated in Figs. 1, 2, 3, 4, 5, 6 and 7 may be formed in any suitable
manner and may be formed in any position in such bars or plates which may be
suitable and may be made of any suitable size. The size of the notch, perfora-
tion, opening, slit or slot, or notches, perforations, openings, slits or slots employed
will require to be adapted to the thickness of the metal of which the bar or plate
in which such notch, perforation, opening, slit or slot, or notches, perforations,
openings, slits or slots is or are formed so that the bar or plate will not be unduly
weakened by the formation of such notch perforation, opening, slit or slot or notches
perforations, openings, slits or slots. A notch or notches (a) of the size indicated

page_text: in Figs. 1, 2 and 3 may be employed when the thickness of the bar or plate is
about one seventeenth of an inch but if a thicker bar or plate be employed the
notch or notches (a) formed in it may be made to extend through a greater part
of the depth of the bar or plate and if a thinner bar or plate be employed, the
notch or notches (a) formed therein must be made smaller so as not to unduly
weaken the bar or plate.
According to another mode of accomplishing the object of my invention I secure
or forin upon or in each of the said bars or plates and upon or in one or each side
thereof a projection, tooth or spike, or projections, teeth or spikes or serrations
or any combination of any of such devices, of any suitable size and form, and
placed or formed or secured in any suitable position upon or in the bar or plate.
Bars or plates formed according to this mode of accomplishing the object of my
invention are illustrated in Figs. 8, 9, 10, 11, 12, 13, 14, 15, 16, and 17 of the
accompanying drawings. Figs. 8, 10, 12, 14 and 16 being side elevations and
Figs. 9, 11, 13, 15 and 17 cross sections. Figs. 8 and 9 illustrate a bar or plate
provided with projections (e) which are formed by notches () being made in the
bar or plate and the parts (e) between such notches (/) being bent aside the
alternate parts (e) being bent outwards on opposite sides of the bar or plate.
Figs. 10 and 11 illustrate a bar or plate in which are inserted spikes (g) which
project at both sides of the said bar or plate. Figs. 12 and 13 illustrate a bar or
plate formed with projections (h) which are formed by pairs of intersecting nicks
being formed through the bar or plate, and the parts between the nicks so formed
being turned or bent outwards so as to project some on one side of the bar or
plate and some on the other side thereof. Figs. 14 and 15 illustrate a bar or
plate provided with serrations (j) which are formed on narrow strips of metal
secured to the bar or plate some at one side and some at the other side thereof.
Figs. 16 and 17 illustrate a bar or plate upon each side of which are secured
projections (k) which are formed of pieces of metal in the form of thin angle irons
and are secured by rivets or other suitable means to the bar or plate. The pro-
jections (k) on one side of the bar or plate are placed intermediate between those
on the other side of the said bar or plate as is indicated in Fig. 16 in which the
projections (4) upon one side of the bar or plate are indicated by full lines while
those on the other side of such bar or plate are indicated by dotted lines. When
the bars or plates to which the projections (k) are to be applied are intended to
be placed about three-eighths of an inch apart, the projections (4) may be made of
such size that they will project about three sixteenths of an inch from the vertical
surfaces of the bars or plates to which they are respectively secured but if the
said bars or plates are separated by greater or less distances than three-eighths
of an inch the distance to which the projections (k) project may also be made
greater or less.
According to a third mode of accomplishing the object of my invention I form
in or through each bar or plate a notch, perforation, opening, slit or slot, or notches,
perforations, openings, slits or slots or any combination of any of such devices and
also secure or form upon or in either or both of the sides of such bar or plate a
projection, tooth or spike or projections, teeth or spikes or serrations or any com-
bination of any of such devices. Bars or plates formed according to this mode of
accomplishing the object of my invention are illustrated in Figs. 18, 19 and 20 of
the accompanying drawings, Figs. 18 and 20 being side elevations and Fig. 19 a
cross section of that which is shown in Fig. 18. Figs. 18 and 19 illustrate a bar
or plate formed with notches (a) and parts (e) turned some to one side of such bar
or plate and some to the other side thereof. Fig. 20 illustrates a bar or plate
formed with notches (a) and projections (4) similar to those above described.
Some of the bars or plates employed in a grid or grating may be formed or
constructed in one of the three modes above described and some in another or
others of such modes or while some of the bars or plates employed in a grid
or grating are formed or constructed in any of the modes above described or while
some of the bars or plates are formed in one of such modes and some in another or

page_text: 23
others, other bars or plates may be of the kind described in the Specification filed
in respect of my application for Letters Patent No. 6327 dated April 13th 1889 or
of any of the other kinds hitherto in use and in such cases any suitable arrangement
of the various bars or plates employed may be adopted. Bars or plates of one kind
may be placed alternately with bars or plates of another kiud or in case bars or
plates of several kinds are employed the bars or plates of each kind may be
interspersed among bars or plates of the other kinds employed. A very advan-
tageous combination is obtained by placing bars or plates such as are shown in
Fig. 2 alternately side by side with bars or plates such as are shown in Fig. 3 as
in such combination the notches (a) in one bar or plate will not be opposite to the
notches (a) in the adjacent bar or plate, or bars or plates but will be intermediate
between such notches (a), thus notches (a) will be very uniformly distributed
throughout the entire grating or grid formed by the bars or plates. Bars or plates
constructed according to my invention may be made of any suitable material and
may be made of any suitable thickness and may be placed longitudinally, transversely
or diagonally and horizontally or in any suitable inclined position in the "scutchers
or "lap machines" in which they are to be employed, but I prefer that the said
bars or plates should be made of such material and of such thickness that they are
capable of being caused to vibrate by the working of the machines in which they
are to be employed. All of the bars or plates illustrated in the accompanying
drawings are of the form employed when the bars or plates are required to be placed
in an inclined position and to be placed longitudinally in the machine but the
manner in which bars or plates would require to be made if to be employed in
positions other than longitudinal will be apparent without further description to
those conversant with machinery for use in the manufacture of cotton and other
fibrous materials. It is apparent also that the number, arrangement, size and position
of the devices provided in accordance with my invention may be considerably varied.
The devices provided in accordance with my invention render the bars or plates
in or upon which they are formed or provided more capable of preventing or
hindering any motes," leaf, sand or other refuse which may fall or be deposited
between them from the cotton or other fibrous material passing over such bars or
plates from again passing into the stream of cotton or other fibrous material
passing over such bars or plates as the said devices provided in accordance with my
invention furnish parts or edges with which the "motes," leaf, saud or other refuse
deposited between the bars or plates may become engaged so as to be secured to
some extent against passing again into the stream of cotton or other fibrous material
passing over the said bars or plates.
"
The "motes, leaf, sand or other refuse separated from the cotton or other fibrous
material being operated upon in a "scutcher" or lap machine to which my
invention is applied, and deposited in the spaces between the bars or plates of the
grid or grating employed in such scutcher or "lap machine" will be secured or
held between the said bars or plates until it is necessary to remove such "motes,"
leaf, sand or other refuse by the usual method of lowering the door or damper
under the said grid or grating, and the application of my invention to a "scutcher"
or "lap machine" also results in the removal from the cotton or other fibrous
material operated upon of a greater quantity of "mutes," leaf, sand or other refuse
than it has hitherto been possible to remove in a "scutcher or "lap machine "
since, there is, when my invention is employed less opportunity for "motes" leaf,
sand or other refuse to escape from between the bars or plates of the grids
or gratings and pass again into the stream of cotton, or other fibrous material
passing over such grids or gratings than in grids or gratings in which bars or plates
of the forms ordinarily in use are employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is: :—
1. The hereinbefore described means of preventing or hindering the escape from

page_text: "
between the bars or plates of the gratings or grids employed and placed between
the beaters" and " cares in the machines known as "scutchers" or lap
machines," of "motes," leaf, sand, and other refuse which have been deposited
between such bars or plates which means consist in notches, perforations, openings,
slits or slots formed in some or all of the bars or plates of which cach of such
gratings or grids is constructed, substantially in the manner herein before described
in reference to and illustrated in and by Figs. 1, 2, 3, 4, 5, 6 and 7 of the accom-
panying drawings.
"
2. The hereinbefore described means of preventing or hindering the escape from
between the bars or plates of the gratings or grids employed and placed between the
"beaters" and "cages" in the machines known as "scutchers or "lap machines,"
of "motes," leaf, sand and other refuse which have been deposited between such
bars or plates which means consist in projections, teeth or spikes or serrations
secured or formed upon or in some or all of the bars or plates of which each of such
gratings or grids is constructed; substantially in the manner hereinbefore described
in reference to- and illustrated in and by Figs. 8, 9, 10, 11, 12, 13, 14, 15, 16,
and 17 of the accompanying drawings.
"
3. The hereinbefore described means of preventing or hindering the escape from
between the bars or plates of the gratings or grids employed and placed between
the beaters and cages "in the machines known as "scutchers" or "lap
machines," of "motes," leaf sand and other refuse which have been deposited
between such bars or plates which means consist in notches, perforations, openings,
slits or slots formed in and projections, teeth, spikes, or serrations secured or formed
in or on some or all of the bars or plates of which each of such gratings or grids
is constructed substantially in the manner hereinbefore described in reference to
and illustrated in and by Figs. 18, 19 and 20 of the accompanying drawings.
