Improvements in the Machines known as "Scutchers' ог Lap
Machines" and used in the "Preparation" of Cotton and other
Fibrous Materials.
I, WILLIAM HURST of Rochdale in the county of Lancaster, Cotton Spinner do
hereby declare the nature of this invention to be as follows:-
"
"
My invention relates to the machines known as scutchers" or "lap machines
and used in "preparing "cotton and other fibrous materials and relates more parti-
cularly to the gratings or grids placed between the "beaters and the "cages" used
in such machines and consists in arrangements by which I am enabled to alter the
positions of the bars or grids of the said gratings or grids so that such bars or grids
may be in such position as may be most effective for operating upon the cotton or
other fibrous material.
According to one method of carrying my invention into effect I employ a grating
or grid formed of bars or plates of metal, wood or other suitable material and so
arrange the alternate bars or plates that they may be raised or lowered by means of
a cam or any other suitable means or secure the said bars or plates in a cross-rail or
frame which cross-rail or frame and the bars or plates secured thereto may be raised
or lowered by means of a cam or levers or in any other suitable manner.
According to another method of carrying my invention into effect I employ a
grating or grid formed of bars or plates of metal, wood or other suitable material
which bars or plates I cause to approach towards or recede from each other as may be
desired. I mount the bars or plates before referred to in suitable guides and cause
them to approach towards or recede from each other by means of a shaft or shafts
formed with a screw-thread or screw-threads, preferably of variable "pitch" or by
means of a shaft or shafts provided with a number of cams or inclines.
According to another method of carrying my invention into effect I connect the
bars or plates forming the grating or grid together by arins or levers after the manner
of a "parallel ruler" or "lazy tongs so that when required the bars or plates may
be caused to approach towards or recede from each other.

Improvements in the Machines known as "Scutchers"
or
"Lap
Machines" and used in the "Preparation" of Cotton and other
Fibrous Materials.
I WILLIAM HURST of Rochdale in the county of Lancaster, Cotton Spinner do
hereby declare the nature of this invention and in what manner the same is to he
performed, to be particularly described and ascertained in and by the following
statement :-
ور
"
"
My invention relates to the machines known as scutchers" or "lap machines
and used in "preparing cotton and other fibrous materials and relates more parti-
cularly to the gratings or grids placed longitudinally, diagonally, cross wise, or in any
other position between the "beaters" and the " cages" used in such machines and
consists in arrangements by which I am enabled to alter the positions of the bars or
grids of the said gratings or grids so that such bars or grids may be in such position as
may be most effective for operating upon the cotton or other fibrous material.
According to one method of carrying my invention into effect I employ a grating
or grid formed of bars or plates of metal, wood, or other suitable material and so

page_text: arrange the alternate bars or plates that they may be raised or lowered by means of a
cam or any other suitable means or secure the said bars or plates in a cross-rail or
frame which cross-rail or frame and the bars, grids or plates secured thereto may be
raised or lowered by means of a cam or levers or in any other suitable manner.
In the accompanying drawings Fig. 1 is a vertical section, and Fig. 2 is a plan of
that which is shown in Fig. 1. A is the beater and B is the cage. The gratings or
grids to which my invention relates are the gratings or grids C situate between
the beater A and the cage B, and over which the cotton or other fibrous material
passes from the beater A to the cage B. Fig. 3 is a plan, Fig. 4 is a cross section
of that which is shown in Fig. 3.
Fig. 5 is a view looking in the direction from D to E in Figs. 3 and 4. Fig. 6 is
a view looking in the direction from D to F in Figs. 3 and 4. Fig. 5 is similar to
Fig. 5 but shows certain parts in a changed position. Fig. 6 is similar to Fig. 6 but
shows certain parts in a changed position. Fig. 7 is an elevation showing arrange-
ments by means of which certain parts are raised and lowered. Fig. 8 shows certain
parts in the positions which they occupy when raised. Fig. 9 shows arrangements
for operating certain parts. The same letters of reference are applied to corresponding
parts throughout the whole series of figures.

The grating or grid I form of bars or plates a of metal, wood, or other suitable
material, but preferably of steel. Extending across between the side-frames G of the
* scutcher"
"
or lap machine are cross-bars b. c. which are secured by bolts to
the side-frames G. The cross-bar c is placed against the cross-plate d which is
ordinarily employed in "scutchers or "lap machines." Secured to the cross-
barb by screws e', one only of which is shown in Figs. 7 and 8, are plates e and
between the plates e and cross-har b I place a plate f. In the upper edge of the
plate e I form notches e² in which at times rest the projecting ends a¹ of the plates
or bars a which are adjacent to the cross-bar b. In the upper edge of the plate f
I form notches into which pass projecting parts formed on the ends a¹ of the
plates or bars a before mentioned.
Certain of the notches f¹ are of one depth but every alternate notch is formed
deeper than the notches alternate therewith. I form on the cross-bar b ribs h, j
situate between which is a bar k capable of being slidden longitudinally between
the ribs h, j. 1 form in the bar inclines 7 shown in Figs. 7 and 8 which
inclines are situate at times below inclines m secured to and projecting from the
plate When the bar is moved in the direction indicated by the arrow H by
means of the handle n until the inclines are in the position in which they are
indicated in Fig. 8 the inclines I will have acted upon the inclines m and raised the
plate so that its upper edge will be raised above the upper edge of the plate e.
To the cross-bar e by means of screws is secured a plate o. Between the plate o and
the cross-bar c is a plate p capable of being moved upward and downward between
the plate o and cross-bar c by means of inclines formed upon a bar q capable of
being slidden longitudinally between ribs c¹, c* formed on the cross-bar c which.
inclines act against inclines formed upon the plate p. The inclines upon the bar q
and the inclines upon the plate p are similar in construction and operation to the
inclines and m previously described.
I form in the plate o a number of holes each alternate hole being elongated in
an upward direction. In the plate p I form a number of holes p¹ the alternate boles
being elongated in a downward direction. The elongated holes p' in the plate pare
situate behind the round holes r in the plate o. Projecting parts a³ formed on the
bars or plates a pass through the elongated holes in the plate o and into the round
holes formed in the plate p.
The plates or bars a I form of thin sheet metal. I have found plates or bars a of
a thickness of about three-sixteenths of an inch to be very suitable for the purpose
of my invention, but plates or bars a little thinner or a little thicker may be employed
according as the gratings or grids C are made of less or greater length. The bars
or plates a by being supported upon the parts a¹, a' are at liberty to be oscillated
upon the plates e, f and o, p

During the working of the "scutcher or "lap machine the cotton or other
fibrous material passing from the beater A to the cage B will travel over the
grating or grid C. Any "motes," seed, dirt or other matter separated from the
cotton or other fibrous material will be readily able to pass between the plates or
bars a of which the grating or grid C is formed, the vibration and oscillation of
the plates or bars a assisting the passage of "motes,” seeds, or dirt, or other matter
down between the plates or bars a.
When the "scutcher " or "lap machine" is operating upon cotton or other
fibrous material of short staple the plates or bars a of the grid or grating C may
be in the position in which they are shown in Figs. 5 and 6, but, when the
"scutcher" or "lap machine" is intended to operate upon cotton or other fibrous
material of long staple the bars k and q are drawn in the directions indicated by the
arrows H.
The movement of the bar k in the direction indicated by the arrow H
will cause the inclines to act upon the inclines m and move the bar f into the
raised position in which it is shown in Figs. 5* and 8. The raising of the bar f will
cause the ends a³ of the alternate bars or plates a to be raised by means of the
shallow notches f¹, the ends of the deeper notches not being raised sufficiently to act
upon the projecting parts upon the bars or plates a. By the bar q being moved in
the direction indicated by the arrow H the end at of the said bars or plates a will be
raised in a manner similar to that in which the ends a³ were raised. When the
alternate bars or plates a are in the raised position as shown in Figs. 5 and 6 the
fibres of cotton, wool, or other fibrous material are supported by and travel along
the upper edges of the raised bars or plates a while any dirt, motes, short fibre or
other foreign matter falls beneath the grating or grid through the spaces between
the raised bars or plates a and the bars or plates a not raised. The vibration of the
raised bars or plates a and of the bars or plates a not raised prevents the spaces
between the bars or plates a from becoming choked and also tends to assist the cotton
or other fibrous material to travel along the upper edges of the bars or plares a which
have been raised.
By the projecting parts a' formed on the ends of the plates or bars a passing into
holes formed in the plates o. p. the plates or bars a are prevented from being
accidentally raised, and coming into contact with the beaters A.

Instead of being placed in the direction of the length of the "scutcher or "lap
machine," the plates or bars may be placed across or in a direction inclined to the
length of the scutcher" or 6
lap machine." The plates or bars a may also be
placed in a horizontal position or in any suitable inclined or sloping position as may
be desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
وو
1. In a « scutcher or "lap machine," grids or gratings C formed with bars or
plates a of which alternate ones may be raised or lowered when required.
"
2. In the grid or grating C of a "scutcher or "lap machine," bars or plates a
provided with projecting parts resting in notches and holes in plates and arranged
to be free to vibrate and oscillate and raised and lowered when required by means
of inclines acting in conjunction with inclines substantially as hereinbefore described
in reference to and illustrated in and by the accompanying drawings.
3. In the grid or grating C of a scutcher." or "lap machine plates e. f. o.
and p provided with notches and holes, and arranged to be moved by means of bars
provided with inclines substantially as herein before described for the purpose of
supporting and moving the bars or plates a of the grid or grating C.
