"Revolving Flats" are Employed.
We THOMAS KNOWLES of Fir Tree Cottage Chapeltown Turton near Bolton in
the County of Lancaster Cotton Spinner and ROGER TATHAM of Moss Lane Iron
Works Moss Lane Rochdale also in the County of Lancaster Machine Maker do
hereby declare the nature of this invention to be as follows:-
Our invention relates to those carding-engines in which. "revolving flats" are
employed and our invention consists in arrangements of apparatus for grinding the
"flats" employed in such carding-engines.
For the purpose of our invention we cause the "back" of each end of the "flat"
about to be ground to travel along an inclined surface and pass between the inclined
surface and a fixed guide. Each of the inclined surfaces and fixed guides is mounted
upon or connected in any suitable manner to one of the "bends" or side-frames or any
other suitable part of the carding-engine so as to be capable of being adjusted in
position.
For convenience of description we shall hereinafter in many instances, only refer to
the apparatus situate at one side of the carding-engine-although the arrangements of
apparatus in which our invention consists and the apparatus used in connection with
our invention are in so far as may be necessary applied alike to each side of the
carding-engine-Each end of the "flat" about to be "ground" is conducted by one
of the inclined surfaces and fixed guides above mentioned, between parts capable of
being slidden in slides one of which parts we shall for convenience call the "support-
ing guide" while we shall refer to the others as "holding guides."
The said slides are secured to the "bend" or framework or other suitable part of the
carding-engine-One end of the "back" of each "flat" "travels" in contact with one
of the supporting guides which supporting guide is forced forwards by means of a
weight or spring or other suitable means and thus caused to force against the fixed
guide one portion of that part of the "flat" which when the "flat" is "at work
upon the flexible bend or other surface with which the end of the "flat" is in
rests

page_text: contact when such "flat" is "at work "-The "flat" while passing over the supporting
guide above referred to is held firmly in contact with such guide by passing beneath
one of the holding guides before mentioned each of which is forced forward by a
weight or spring or other suitable means-One of the ends of each of the said holding
guides is formed inclined so that while the "flat" passes beneath such inclined end the
said inclined end will be pressed upon the inclined portion of the "flat" by which the
"flat" is "heeled" when "at work "Before the "flat" has left the first holding
guide the advancing edge of such "flat" passes between the second holding guide and
the supporting guide which second holding guide acts upon the "flat" in a manner
similar to that in which the first holding guide acted upon the "flat."
After the end of each of the "flats" has passed beneath the second holding guide
the end of such "flat" passes along an inclined surface from which the "flats" pass
into "working position"-While the "flats" are travelling beneath the holding
guides they pass beneath the grinding roller which grinds the "wire" or teeth―The
"wiro" or teeth of each "flat" while passing beneath the grinding roller is or are
ground so as to be of equal or uniform height or length from the "face"
foundation" of the "flat" upon which the "wire or teeth is or are mounted.
"
ог
We mount the grinding roller in suitable bearings by means of which it may be
adjusted in any suitable manner into the desired position for grinding the "wire" or
teeth of the "flats."

We THOMAS KNOWLES of Fir Tree Cottage Chapeltown Turton near Bolton in the
County of Lancaster Cotton Spinner and ROGER TATHAM of Moss Lane Iron Works
Moss Lane Rochdale also in the County of Lancaster Machine Maker 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 :-
Our invention relates to those carding-engines in which "revolving flats" are
employed and our invention consists in arrangements of apparatus for grinding the
"flats" employed in such carding-engines.
"
"
For the purpose of our invention we cause the "back" of each end of the "flat"
about to be " ground to travel along an inclined surface and pass between the
inclined surface and a fixed guide. Each of the inclined surfaces and fixed guides is
mounted upon or connected in any suitable manner to one of the "bends
frames or any other suitable part of the carding-engine so as to be capable of being
adjusted in position.
or side
For convenience of description we shall hereinafter in many instances only refer to
the apparatus situate at one side of the carding-engine although the arrangements of
apparatus in which our invention consists and the apparatus used in conjunction with
our invention are in so far as may be necessary applied alike to each side of the
carding-engine.
In the accompanying drawing Fig. 1. is a front view and Fig. 2 a side view showing
so much of a carding-engine as is requisito to illustrate our invention.
The same letters of reference are applied to corresponding parts in both of the
figures.
Secured to the "bend" of the carding-engine is a bracket a. To a projection a'
formed upon the bracket a. is secured the curved bracket balong the upper edge b¹ of
which the "revolving flats" c travel when away from the "main cylinder" of the
carding-engine. Mounted upon the bracket a. and secured thereto by the bolt d. and
nut is a bracket e. The said bracket e. is formed with a part e¹ the lower edge
of which is formed with two surfaces e² connected by an inclined surface e'.
Secured to the bracket a by the nut f¹ is a stud f mounted upon which and free to be
turned thereon is a lever g one end g' of which is formed with a flat or nearly flat
surface extending from A to B and inclined surfaces g³g. The other end of the
lever g is provided with a weight g³ which tends to turn the end g¹ of the lever in
the direction indicated by the arrow C. In place of the weight 9 a spring or other
equivalent for such weight 9' may be employed. Mounted upon the bracket a. is a
bracket h which supports so that it may be turned therein one end of the axle j¹ of the
grinding roller j. The bracket is provided with the screws and nuts by means of
which the grinding roller j. can be adjusted into the required position but as such
screws and nuts are similar to those ordinarily in use for similar purposes we have
g.

omitted them from the drawing in order to avoid confusion. One end of each of the
"flats" c. while away from the main cylinder of the carding-engine passes between the
end g¹ of the lever g and the bracket e. c², c³, c³ are "flats"-The "flat" c³ is about
to be ground the "flat" c is being "ground" by the grinding roller ; and the
"flat" has been "ground." The motion of each of the flats c in the direction
indicated by the arrow D causes each of such "flats" c to pass beneath the grinding
roller j―The portion of each of the flats c which at times is against the surfaces e, e
of the bracket e is that portion of the "flat" which is supported by the flexible
"bend or other "bend "when the said "flat" c is "at work "The movement of the
"flats" in the direction indicated by the arrow D will cause the portion of each of
such "flats" to travel along the inclined surface g' and the surface g² of the lever
The weight go will cause the end c of the flat c to be pressed against the surfaces e²e
of the bracket e. The movement of the "flat" c in the direction indicated by the
arrow will cause the edge c of the "flat" to pass along the surface e and
the edge to travel along the surface e-While the edge c' is travelling along
the surface and while the edge c8 is supported on the surface, e³ the "wire
surface" c of the
flat"
c will be operated upon by the grinding roller ; which is
caused to rotate in the manner in which grinding rollers are ordinarily caused to
rotate.

Fig. 3 is a detached view showing upon a larger scale the grinding roller j and a
section of a "flat" being ground the surfaces e e³ and inclined surface e being
shown by a single line only in order that confusion may be avoided-The surface e³ is
formed at such a height above the surface e that when the edge c' of the "flat" c is
travelling along the surface e³ and the edge 8 of the "flat" c is travelling along the
surface the "flat" c will be tilted in the direction indicated by the arrow E so
that the surface F F of the "flat" c will be parallel to the surface e² and the surface e³
and that the "card wire surface "of the "flat c will be ground parallel to the
surface F, F of the "flat
After the
c to which the "card wire" is attached.
"wire" of the "flat" c has been operated upon by the "grinding roller "j, a cou-
tinued movement of the "flat" c in the direction indicated by the arrow D will carry
the "flat" clear of the surfaces e², e³ and the surface g* upon the lever g-By causing
the edges c, c of each "flat c to travel along the surfaces e³, e while the "flat" c is
being "ground" we ensure that the wire of all the "flats" shall be ground
uniformly in relation to the surfaces by. which such "flats"
