I, JOHN DODD, of Hartford Works, Oldham, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention consists in improvements in means for securing card-clothing
to the cylinders of carding-engines.
According to this invention, I cause the ordinary taper plug-holes in the carding-
engine cylinder-ends to which this invention is to be applied to be tapered or
countersunk for a certain distance from the inner surface of the cylinder. The
plurs when driven into the said holes are secured by the usual pegs or wedges
being driven into them. The inner taper allows the plugs to expand so as to
form a double cone when the pegs or wedges are driven into them and permits
of the inner surface of the cylinder being turned true and smooth without endanger-
ing the security of the plugs.

Improvements in Means for Securing Card-clothing to the Cylinders
of Carding-engines for Carding Cotton, Wool and other Fibrous
Materials.
I, JOHN DODD, of Hartford Works, Oldham, in the County of Lancaster,
Engineer, 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:
-
This invention consists in improvements in means for securing card-clothing
to the cylinders of carding-engines.
According to this invention, I cause the ordinary taper plug-holes in the carding-
engine cylinder-ends to which this invention is to be applied to be tapered or
countersunk for a certain distance from the inner surface of the cylinder. The
plugs when driven into the said holes are secured by the usual pegs or wedges

ing the security of the plugs.
In the accompanying drawings, Fig. 1 is a longitudinal section of so much of
the cylinder of a carding-engine as is requisite for the illustration of this inven-
tion, Fig. 2 is a longitudinal section of one of the wooden plugs employed accord-
ing to this invention before insertion in the cylinder of a carding-engine and
Fig. 3 is a side elevation of one of the square wooden pegs or wedges used in
securing in position the plugs which are employed according to this invention.
In Fig. 1, a is the cylinder to which the card-clothing 6 is to be secured,
the leather or cloth or other foundation in which the wires & forming the card-
surface of the card-clothing b are secured and e is one of the fixed bends adjacent
to the cylinder a.

According to this invention, I cause such of the taper plug-holes
rding-engine-cylinder a as are to have this invention applied to them, to be
tapered or countersunk for a certain distance from the inner surface 9 of the
cylinder a so that such holes f shall be tapered from both the outer and inner
faces of the cylinder a. The plugs h when driven into the said holes f are secured
by the usual pegs or wedges j being driven into the plugs h. The inner taper
allows the plugs h to be expanded by the driving in of the pegs or wedges j so as
to form double cones when the pegs or wedges have been driven into them, and
enables the plugs h to resist disturbance and be secured against both inward and
outward displacement and thus, which is the object of this invention, permits of
the inner surface of the cylinder a being turned true and smooth without
endangering the security of the plugs and permits of the nails or tacks being
driven into the plugs to secure the foundation of the clothing to the cylinder
without disturbing such plugs.

This invention is applicable to all the cylinders which are used in carding-
engines and require to be covered with wire-clothing, whether main cylinders,
doffer cylinders, rollers or workers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:
The hereinbefore described method of securing in carding-engine-cylinders the
plugs to which the card-clothing is to be secured which consists in forming in
such cylinders, holes such as f countersunk or made to taper from both the outer
and inner faces of the cylinders so that the wooden plugs inserted therein and
fastened by pegs or wedges driven into them may expand into the form of double
cones and thus be firmly and permanently fixed in such holes.
