Improvements in Carding-engines for Carding Cotton and other
Fibrous Materials.
We WILLIAM HALL RICHARDSON of Bank View, Derker Oldham in the county
of Lancaster, Machinist and WILLIAM GREAVES of 279 Park Road Oldham in the
county of Lancaster Foreman both in the employ of Messieurs Platt Brothers and
Company Limited of Oldham aforesaid Machinists, do hereby declare the nature of
this invention to be as follows
*
The object of the first part of our invention is to enable carding engines to be made
of less width in proportion to the width of the "card surface" of such carding engines
than they have hitherto been. In accomplishing this object we place the bends or a
great part of each bend of the carding-engine within the ends of the cylinder of the
carding-engine. To enable the bends to be so placed we place the rings which secure
the cylinder to the axle upon which it is mounted a sufficient distance inside the
ends of the cylinder to leave room for the said bends. To the bends above-mentioned
we secure the various brackets and attachments necessary to be secured to such bends.
This part of our invention may be used in conjunction with any ordinary arrange-
ment of flats " or "rollers. A further part of our invention relates to the carding-
engines in which either revolving or stationary flats are employed and relates more
particularly to the flexible bends used in such carding-engines aforesaid and consists
in arrangements by which each of such flexible bends is so mounted upon the bend
to which it is applied that it can be adjusted relatively to the card surface" of the
main cylinder of the carding-engine with greater ease and and certainly than heretofore.
In carrying this part of our invention into effect we mount upon the bend of the
carding-engine a bracket capable of being moved nearer to or farther from the axis
of the main cylinder of the carding-engine by means of a screw such bracket being
secured to the bend by a
"set screw
or bolt. We provide the said bracket with a
projecting stud or part or knife-edge "or like appliance or a recess upon or in
which the flexible bend is mounted so as to be capable of being turned thereon or
therein. By means of the screw and bracket before-mentioned and the screws and
"

page_text: brackets provided with studs projecting into slots formed in the flexible bend, the said
flexible bend may be adjusted relatively to the "card surface" of the main cylinder.
By the arrangements described above in reference to this part of our invention the
flexible bend may be adjusted relatively to the "card surface" of the main cylinder
of the carding-engine with greater ease and certainty than heretofore.
A further part of our invention relates to the brackets for adjusting and securing
the extremities of the flexible bends in relation to the "card surface" of the main
cylinder. Instead of forming slots in the extremities of the flexible bend as heretofore
we secure a stud or projection to each of the ends of each flexible bend which studs
pass into slots which we form to receive them in the brackets which are employed to
adjust the ends of the flexible bend relatively to the "card surface" of the main
cylinder and to secure them in position when adjusted. By means of the arrange-
ments above described in reference to this part of our invention the person adjusting
the flexible bend in position is enabled to see if the studs or projections are hindered
in any way from moving in the slots and by the said arrangement any dirt or fibre
which may enter into the slots aforesaid may be readily removed from such slots
whenever requisite.
We have above referred to certain parts as being employed upon one side only of
the carding-engine whereas like parts are employed upon the other side of the carding
engine but we would have it understood that in all cases where it is requisite we
employ corresponding parts upon both sides of the carding engine.
We have hereinbefore described the various parts of our invention as being used
separately but any two or all of them may be used in combination if desired.
We have herein before described the manner in which our invention is applied to
a carding engine having one cylinder" but our invention is applicable to carding
engines each of which is provided with two or more "cylinders."

Improvements in Carding-engines for Carding-cotton and other
Fibrous Materials.
We WILLIAM HALL RICHARDSON of Bank View, Derker, Oldham in the County of
Lancaster, Machinist and WILLIAM GREAVES of 279 Park Road, Oldham in the
County of Lancaster Foreman both in the employ of Messieurs Platt Brothers and
Company Limited of Oldham aforesaid Machinists 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 :-
The object of the first part of our invention is to enable carding-engines to be made
of less width in proportion to the width of the "card surface" of such carding-engines
than they have hitherto been. In accomplishing this object we place the bends or a
great part of each bend of the carding-engine within the ends of the cylinder of the
carding-engine. To enable the bends to be so placed we place the rings which secure
the cylinder to the axle upon which it is mounted a sufficient distance inside the ends
of the cylinder to leave room for the said bends. To the bends above mentioned
we secure the various brackets and attachments necessary to be secured to such bends.
This part of our invention may be used in conjunction with any ordinary arrange-
ment of "flats" or ** rollers."
This part of our invention is illustrated by Figs. 1. 2. 3 and 4 of the accompanying
drawings, Fig. 1 being a side elevation of so much of a carding-engine as is
requisite to illustrate our invention and Fig. 2 a cross-section on a larger scale taken
on the line A A of Fig. 1. Fig. 3 shows upon a larger scale a portion of that which
is shown in Fig. 1, and Fig. is a cross-section taken on the line B B of Fig. 1.
The same letters of reference are applied to corresponding parts throughout the
whole series of figures. Although the accompanying drawings show one side only of
the carding-engine we would have it understood that this first part of our invention
is applied to both sides of the carding-engine. We place the bends a of the carding-
engine within the ends of the cylinder of the carding-engine.
The bends a are secured to the side-framings c of the carding-engine by bolts and
nuts. To enable the bends a to be so placed we place the rings d'which secure the
cylinder & to the axle & upon which such cylinder b is mounted, a sufficient distance
inside the ends of the cylinder b to leave room for the bends a. To the bends a
we secure the various brackets and attachments necessary to be secured to such bends.
We place the flexible bend e near to the edge 3 of the cylinder and on the outside
of the bend a and to protect the edge of the wire and prevent the escape of fibre
and dirt we secure an annular plate of metal to the edge 3 of the cylinder b. The
annular plate g of metal also prevents dirt and fibre from passing into the space
between the end of the cylinder & and the bend a.
I
A further part of our invention relates to the carding-engines in which either
revolving or stationary flats are employed and relates more particularly to the
"

page_text: flexible bends used in such carding-engines aforesaid and consists in arrangements
by which each of such flexible bends is so mounted upon the bend to which it is
applied that it can be adjusted relatively to the "card surface" of the main cylinder
of the carding-engine with greater case and certainty than heretofore. In carrying
this part of our invention into effect we mount upon the bend of the carding-engine
a bracket capable of being moved nearer to or farther from the axis of the main
cylinder of the carding-engine by incans of a scrow, such bracket being secured to
the bend by a << set screw or bolt. We provide the said bracket with a projecting
*
stud or part or
knife-edge" or like appliance or a recess upon or in which the
flexible bend is mounted so as to be capable of being turned thereon or therein. By
means of the screw and bracket before mentioned and the screws and brackets
provided with studs projecting into slots formed in the flexible bend the said flexible
bend may be adjusted relatively to the "card surface" of the main cylinder. This
part of our invention is also illustrated by Figs. 1. 2. 3. and 4 of the accompanying
drawings.
32
Upon the bend a we mount ribs or guides upon which we mount a bracket j
capable of being moved upon the ribs or guides / nearer to or farther from the
axis of the main-cylinder & by means of an adjusting screw k which takes into screw-
threads formed in the bracket. The screw is prevented from moving longitudinally
by the head and collar k². The bracket is secured to the bend a by means of
the "set screw
I which screws into a boss a' formed on the bend a. The set screw l
passes through a slot formed through the bracket j. In order that the set-
screw may be conveniently screwed and unscrewed we form a hole m¹ through
the bracket m and cause the head of the set screw to project above the surface
of the said bracket m so that a key may be readily applied to the head of the
set screw 7. Screwed into or otherwise secured to the bracket j is a stud n upon
which and free to be turned thereon we mount the flexible bend e. The stud n
is provided with a flange n' secured to the stud n by a screw by which
flange the flexible bend e is prevented from being moved laterally. The ends el e²
of the flexible bende may be acted upon by any of the arrangements ordinarily
employed for adjusting the surface e³ of the flexible bend e relatively to the "card
surface of the main cylinder b. When the ends e, e² of the flexible bend e are
being adjusted to the card surface" of the main cylinder the flexible bend e being
at liberty to turn upon the stud n the strain placed upon either end of the flexible
bend e will be distributed throughout the entire length of the flexible bend e thereby
enabling the flexible bend e to be adjusted into a correct position with greater ease
and certainty than heretofore. In place of the stud n a knife-edge or like appliance
or recess may be employed to support the flexible bend which may be mounted upon
or in such knife-edge or like appliance or recess. The arrangements in which this
part of our invention consists are applied to both sides of the carding-engine. We
would have it understood that we also propose to employ flexible bends mounted as
above described in conjunction with any ordinary arrangement of bend.
5.
By the arrangements described above in reference to this part of our invention the
flexible bend may be adjusted relatively to the "card surface" of the main cylinder
of the carding-engine with greater ease and certainty than heretofore.
A further part of our invention relates to the brackets for adjusting and securing
the extremities of the flexible bends in relation to the "card surface" of the main
cylinder. Instead of forming slots in the extremities of the flexible bend as hereto-
.fore we secure a stud or projection to each of the ends of each flexible bend which
studs pass into slots which we form to receive them in the brackets which are
employed to adjust the ends of the flexible bend relatively to the "card surface" of
the main cylinder and to secure them in position when adjusted. By means of the
arrangements above described in reference to this part of our invention the person
adjusting the flexible bend in position is enabled to see if the studs or projections
are hindered in any way from moving in the slots and by the said arrangements any
dirt or fibre which may enter into the slots aforesaid may be readily removed
from such slots whenever requisite. This part of our invention is illustrated by

page_text: "
Figs. 1. 3. 4 and 5 of the accompanying drawings-Fig. 5 being a side view upon a
larger scale of the flexible bende which is shewn partly by dotted lines in Fig. 1.
Upon the bend a we mount a bracket o. Screwing into the part o¹ of the bracket o
is a screw p which is capable of being turned in a projecting part a² formed upon the
bend a.
The screw is prevented from moving longitudinally by means of the
head and a collar p² secured upon the screw p. Through the bracket o we form a
slot through which passes a "set screw
9 screwing into a boss a³ formed on the
bend a.
Upon the bend a we form guides upon which the bracket o may be moved
longitudinally by means of the screw p. To the bend a we secure a bracket s.
Screwing into a part of the said brackets is a screw t which is capable of being
turned in a projecting part a² formed upon the bend a.
The screw is prevented
from moving longitudinally by means of the head t¹ and a collar secured upon the
screw t. Through the brackets we form a slot 2 through which passes a
"set screw 11
screwing into a boss formed on the bend a. Upon the hend a we form guides » upon
which the brackets may be moved longitudinally by means of the screw t.
To the end e¹ of the flexible bend e we secure a stud et which stud
through a slot o³ formed in the bracket o. We provide the stud e with a nut e by
which the stud e is prevented from being moved longitudinally.
::
projects
To the end e² of the flexible bend e we secure a stud which stud e projects through
a slot 3 formed in the bracket s. We provide the stud as we do the stud et with a
nut by which the stud e is prevented from being moved longitudinally. The nuts
upon the studs e and ef are omitted in Fig. 1 in order that the slots o³, 3 may be
shown. When the flexible bend e is being adjusted so that the surface e³ of such
flexible bende which supports the "flats" when at work shall be in a suitable position
relatively to the "card surface" of the main cylinder, the brackets o and s are
moved by the screws p and t farther from or nearer to the axis of the main cylinder b
of the carding-engine as may be required and the stud n is moved so as to be farther
from or nearer to the axis of the main cylinder 6 in a manner which is apparent from
the drawings. The slots o³ and s³ permit the movement of the studs e, e con-
sequent upon the bending of the flexible bend e caused by the adjustment of such
flexible bende to take place. Hitherto it has been customary to form slots in the
ends of the flexible bend into which studs projecting from the brackets by which
the flexible bend has been adjusted have passed and such slots being behind the
bend have been liable to be filled with dust and dirt which from the position of the
slots could not be readily removed therefrom and such dust and dirt seriously interfered
with the adjustment of the flexible hend. By this part of our invention the
slots o³, are exposed to view and in case dust or dirt should have accumulated in
the slots o³, it can readily be removed therefrom.
When the flexible bend e is being adjusted into position the slots o³, 3 and
studs e, e can be readily inspected to ascertain if either of the studs e, e is in
contact with the end of the slot into which such stud passes or if either of the
studs e, e is hindered in any way from moving in the slot into which such stud
passes. We would have it understood that parts similar to those described in
reference to this part of our invention are applied to both sides of the carding-
engine although but one side of the carding-engine is shown in the accompanying
drawings.
The brackets w support the axle of the roller employed to grind the "wire" of
the "flats." The brackets o, m, and s are respectively provided with parts which
support the axles of the rollers or pulleys around which pass the chains y by
which the "flats are secured together. The brackets are employed for the purpose
of tightening the chains y to which the "flats" are connected.

We have hereinbefore described the various parts of our invention as all applied to
one carding-engine but any one or two of them may be used without the others or
other if desired.
We have hereinbefore described the manner in which our invention is applied to a
carding-engine having one cylinder but our invention is applicable to carding-
engines each of which is provided with two or more cylinders.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what wo
claim is :-
-
1. The hereinbefore described arrangement according to which the bends of a
carding-engine are wholly or in great part placed within the ends of the cylinder of
the carding-engine for the purposes and substantially in the manner herein before
described in reference to and indicated in and by Figs. 1. 2. and 4 of the accompanying
drawings.
2. The herein before described arrangement according to which each of the flexible
bends of a carding-engine is mounted for the purpose and substantially in the manner
hereinbefore described in reference to Figs. 1 and 2 of the accompanying drawings,
