PROVISIONAL SPECIFICATION.
Improvements intended to Facilitate the Adjustment and the Testing
of the Adjustment of the "Travelling Flats" in relation to the
" Cylinders employed in Revolving Flat Carding-engines for
Carding Cotton and other Fibrous Materials.
I, WILLIAM HALL RICHARDSON, of Hartford Iron Works, Oldham, in the
County of Lancaster, Machinist, do hereby declare the nature of this invention to
be as follows :-
My invention relates to revolving flat carding-engines for carding cotton and
other fibrous materials and consists in arrangements by which I am enabled to
facilitate the adjustment and the testing of the adjustment of the "travelling flats"
to the "cylinders" of such carding-engines.
According to my invention I form a number of slits or openings in or through
the flexible bends or other like surfaces on which the flats slide when carding
cotton or other fibrous material. The said slits or openings are placed in such
position that a suitable gange or strip of metal or suitable gauges or strips of metal
may be passed through each slit or opening and pushed forwards to and between
the points of the card wire on the "cylinder" and the points of the "card wire " on
the "flat" the adjustment of which is to be tested.
When the slits or openings are not being actually used they may be closed by
means of suitable plugs or covers provided for the purpose and thus "fly" or dust
may be prevented from being blown out through such slits or openings by the
rotation of the cylinder. I prefer to connect the said plugs or covers by means of
chains or in any other suitable manner to the bends or other parts of the carding
engines so that the loss or injury of such plugs or covers is prevented.
By my invention I enable the gauging or testing of the adjustment of the "flats"
in relation to the "cylinder" of a revolving flat carding-engine to be effected
without it being necessary to remove any parts or "flats" from the carding-
engine.

"
I, WILLIAM HALL RICHARDSON, of Hartford Iron Works, Oldham, in the
County of Lancaster, Machinist, 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 revolving flat carding engines for carding cotton and
other fibrous materials and consists in arrangements by which I am enabled to
facilitate the adjustment and the testing of the adjustment of the "travelling flats"
to the "cylinders" of such carding engines.
According to my invention 1 form a number of slits or openings in or through the
flexible bends or other like parts on which the flats slide when carding cotton or
other fibrous material. The said slits or openings are placed in such position that
a suitable gauge or strip of metal or suitable gauges or strips of metal may be

page_text: "
passed through each slit or opening and pushed forwards to and between the points
of the card wire on the "cylinder" and the points of the "card wire
on the "flat"
the adjustment of which is to be tested.
When the slits or openings are not being used for testing the adjustment of the
flats they may be closed by means of suitable plugs or covers provided for the
"
purpose and thus "Ay or dust may be prevented from being blown out through
such slits or openings by the rotation of the cylinder. I prefer to connect, the said
plugs or covers by means of cbains or in any other suitable manner to the bends or
other parts of the carding engines so that the loss or injury of such plugs or covers
is prevented.
The accompanying drawing illustrates so much of a "revolving flat carding
engine" as is necessary for the illustration of my invention and the manner in which
it is to ho carried into effect.
Fig. 1 is a side elevation of a portion of a revolving fat carding engine and
Fig. 2 is a cross section of a portion of that which is shown in Fig. 1 taken on
the plane indicated by the line (A. B.) of Fig. 1.
Π
Fig. 3 is a side elevation of the flexible bend" detached showing more clearly
than Fig. 1 the slits or openings formed through such "flexible bend" in accordance
with my invention.
Fig. 4 shows detached one of the plugs or covers employed to close the slits or
openings in the "flexible bend" when such slits or openings are not being actually
used.
In all of the figures the same letters of reference are employed to indicata corre-
sponding parts.
In Figs. 1, 2, and 3 (a) is the "flexible bend" which is supported and held in
position by means of the brackets (b, c, d) which are secured to the bend (e) of the
carding engine. The brackets (b, c, d) are similar in construction to the brackets
in ordinary use. In the flexible bend (a) I form four slits or openings (}, {', f',
and ) of which (", and ") are near to the centre of such flexible bend (a) while
each of the other two slits or openings (and) is situate near one of the ends
of the flexible bend (a). The slits or openings (', ƒ³, and ƒ³) may be formed at
the time the flexible bend is east and are allowed to remain as nearly as possible
in the condition in which they are left by the casting operation in order to ensure
the strength and flexibility of the flexible bend. Each of the slits or openings (f
, and ) is formed in such position in the flexible bend that the surface of contact
or space between the points of the teeth or wire of the flats (9) supported by the
flexible bend (a) and the points of the wire or teeth of the cylinder (4) of the carding
engine may be in line with or nearly in line with the middle of such slits or openings
as shown by (*) in Fig. 2, and that the said slits or openings (and)
shall be parallel to the adjacent edge of the surface of contact or space between
the teeth or wire of the flats (g) and the wire or teeth of the cylinder (h). The
alits or openings (ff, and 3) are formed in such position in order that a
suitable gauge or strip of metal or suitable gauges or strips of metal may be readily
passed through any of such slits or openings and between the teeth or wire of the
flats (g) and the wire or teeth of the cylinder (h).
When the teeth or wire on the flats (g) are to be adjusted in relation to the
wire or teeth of the cylinder (h) a thin strip or gauge of steel or other suitable
material is passed through each of the slits or openings (ƒ'', ƒ³, and ƒª) and pushed
forward to and between the points of the teeth or wire on the flats (g) and the
points of the wire or teeth on the cylinder (4). Such of the brackets (b, c, or d)
as the strips or gauges indicate to require adjustment are then raised or lowered as
may be necessary by means of the screw or screws with which the suid brackets
are provided, until the points of the teeth or wire on the flat (y) the adjustment of
which is to be tested by means of the said strip or gauge assume the desired
position in relation to the points of the wire or teeth on the cylinder (h). When
the adjustment of the points of the wire or teeth of the flats (g) in relation to the
points of the wire or teeth on the cylinder (4) has been completed the strips or

page_text: 2
gauges are removed. It is obvious that by means of the slits or openings (f,ƒ³, ƒ³,
and) the position of the points of the teeth or wire on the flats (9) in relation
to the teeth or wire on the cylinder (h) may be ascertained or tested by means of
suitable strips or gauges of steel or other metal as to whether it is or is not
necessary to adjust the position of the points of the wire or teeth on the flats (9)
in relation to the points of the wire or teeth on the cylinder (h).
When the slits or openings (f, f', ƒ³, and ƒ³) are not actually in use for the
purpose herein before described they may be closed or filled by means of suitable
plugs or covers (i) provided for the purpose and made to fit as tightly as may be
necessary in the said slits or openings. One of the plugs or covers (i) is shown in
Fig. 1 inserted into one of the slits or openings (f) and shown detached in Fig. 4.
The plugs or covers (i) may be connected by chains or cords (j) to any suitable
part of the carding engine in order that such plugs or covers may be prevented
from being lost or mislaid when removed from the slits or openings (f, f', f',
and f). The plugs or covers (i) when inserted in the slits or openings serve to
prevent dust or "fly" or cotton from being driven out through such slits or openings
by the revolution of the cylinder as might be the case were such plugs or covers (i)
not employed.
Although I have in the accompanying drawing shown one side only of the
carding engine would have it understood that the flexible bend at the other side
of the carding engine has formed in it slits or openings similar to and used in the
same manner as the slits or openings (ƒ, ƒ³,ƒ³, and ƒ³)..
Although I have in the accompanying drawing only shown my invention as
applied to a revolving flat carding engine in which the travelling flats are sup-
ported on a flexible bend, I would have it distinctly understood that my invention
may be applied to other constructions of revolving flat carding engines and that
slits or openings similar to and employed in the same way as the slits or
openings (ff, and f) above described may be formed for like purposes
through the parts which in such carding engines support the travelling Hats when
they are acting in conjunction with the card surface of the cylinder of the carding
engine.
By my invention I enable the gauging or testing of the adjustment of the
"flats" in relation to the "cylinder" of a "revolving flat carding engine" to
be effected without it being necessary to remove any parts or "flats" from the
carding engine.
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 I
claim is :-
1. In a revolving flat carding engine, flexible bends or other appliances provided
with slits or openings by means of which the position of the points of the teeth
or wire upon the flats in relation to the teeth or wire of the cylinder may be
ascertained or tested substantially as hereinbefore described.
2. For use in conjunction with slits or openings formed in the flexible bends or
other appliances of a revolving flat carding engine, plugs such as (i) employed to
prevent dust, "fly," or cotton from being blown out through the slits or openings
aforesaid substantially as hereinbefore described.
