PROVISIONAL SPECIFICATION.
Improvements in Means for Securing Card Fillets or Clothing to
Cylinders and Rollers.
1 GEORGE HALL SCHOFIELD of Wellington Mill Greenfield near Oldham in the
County of Lancaster Cotton Spinner do hereby declare the nature of this invention
to be as follows:-
My invention is chiefly applicable to securing card fillets or clothing to the cylinders
and rollers of carding engines.
Heretofore it has been customary to drill taper holes radially through the shell of
a cylinder and plug the same with wooden plugs into which the tacks for securing
the fillet or clothing are driven.
Now according to my invention I dispense with a certain number of holes near and
around each end of the cylinder and instead I drill holes extending say one inch or so
into the cylinder ends parallel to the axis; in drilling these holes I allow the drill
to break through the metal at the outside or I remove the metal subsequently in order
to leave slots or openings of any suitable width say for example if the hole be
seven-sixteenths of an inch in diameter a slot of one quarter of an inch may be
formed; these holes which may be any suitable distance apart are filled with
wooden or other plugs which are then trimmed off .level with the outer surface and
ends of the cylinder and constitute means by which the card fillet or clothing may be
secured to the cylinder..
The holes and plugs may be threaded or the plugs may be otherwise secured if
necessary.
In place of the ordinary radial holes and plugs which may be used in the main
body of the cylinder in combination with the longitudinal plugs at the ends of the
cylinder I propose to form several slots dovetail in cross section and extending from
one end preferably right across the cylinder these slots which may be cut by any
suitable machine are then each filled with a piece or pieces of wood or other suitable
material to which the fillet or clothing is tacked.
It may be possible to core suitable slots in which case they could be filled by
running in molten lead or other suitable substance before the cylinder is turned on
its periphery the lead or other filling facilitating the operation of turning; the card
fillet or clothing would be tacked onto the lead or other substance.
This arrangement of longitudinal slots could be used in combination either with
the arrangement described or any other suitable means for securing the fillet at the
ends of the cylinder.

Improvements in Means for Securing Card Fillets or Clothing to
Cylinders and Rollers.
I, GEORGE HALL SCHOFIELD, of Wellington Mill, Greenfield, near Oldham, in the
County of Lancaster, Cotton Spinner, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention is chiefly applicable to securing card fillets or clothing to the cylinders
and rollers of carding engines.

page_text: Heretofore it has been customary to drill taper holes radially through the shell of
a cylinder and plug the same with wooden plugs into which the tacks for securing the
fillet or clothing are driven.
Now according to my invention I dispense with a certain number of holes near and
around each end of the cylinder and instead I drill holes extending, say one inch or
so, into the cylinder ends parallel to the axis; in drilling these holes I allow the
drill to break through the metai at the outside, or I remove the metal subsequently,
in order to leave slots or openings of any suitable width say for example if the hole
be seven-sixteenths of an inch in diameter a slot of one-quarter of an inch may be
formed; these holes which may be any suitable distance apart are filled with wooden
or other plugs which are then trimmed off level with the outer surface and ends of
the cylinder and constitute means by which the card fillet or clothing may be secured
to the cylinder.
The holes and plugs may be threaded or the plugs may be otherwise secured, if
necessary.
In place of the ordinary radial holes and plugs which may be used in the main
body of the cylinder in combination with the longitudinal plugs at the end of the
cylinder, I propose to form several slots dovetail in cross section and extending from
one end preferably right across the cylinder; these slots which may be cut by any
suitable machine are then each filled with a piece or pieces of wood or other suitable
material to which the fillet or clothing is tacked.
It may be possible to core suitable slots in which case they could be filled by
running in molten lead or other suitable substance before the cylinder is turned on
its periphery, the lead or other filling facilitating the operation of turning; the card
fillet or clothing would be tacked on to the lead or other substance.
This arrangement of longitudinal slots could be used in combination either with the
arrangement described or any other suitable means for securing the fillet at the ends
of the cylinder.
In the accompanying Sheet of Drawings Figure 1 is an end view Fig. 2 a vertical
section and Fig. 3 a plan of part of a carding engine cylinder fitted with my improved
means for securing card fillets or clothing thereto and Figs. 4 and 5 are views of a
modification of the same.
b
Referring first to Figs. 1, 2, and 3-a designates the shell of the cylinder and a¹ the
flange to which is secured the arm by a bolt e; d designates, see Fig. 1, the holes,
a number of which are formed near and around each end of the cylinder; these
holes d are about an inch long or more or less and have part of the outside metal
removed as shown so as to form slots less in width than the diameter of the holes.
The holes d are filled with plugs e of wood or other suitable material which are
trimmed off flush with the surface and ends of the cylinder a.
In addition to the holes d near and around the ends and instead of the ordinary
plugged radial holes in the body of the cylinder, I may form a series of slots fas
shown in Figs. 1 and 3. These slots are dovetail in cross section and extend preferably
right across the cylinder from end to end and are filled with strips of woods or with
lead or other. suitable material.
The card fillets or clothing would be tacked and secured to the strips in the slots f
as well as to the plugs e in the end holes d.
In the modification illustrated by Figs. 4 and 5 I have shown in Fig. 4 a cored
slot which in Fig. 5 is shown as having been filled by running in molten lead or
other suitable substance before the cylinder has been turned and reduced in diameter
as represented in Fig. 5.
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 :-
:-
1. Dispensing with the ordinary radial holes and plugs and instead forming
longitudinal holes or slots in the metal shell near and around each end of the cylinder,

page_text: said holes or slots being filled with wood, lead or other suitable material to which
the card fillets or clothing can be tacked and secured substantially as herein set
forth.
2. Dispensing with the ordinary radial holes and plugs in the body of the cylinder
and instead forming slots extending preferably longitudinally from end to end of the
cylinder, said slots being filled with wood, lead or other suitable material substantially
as herein set forth.
3. The combination with the series of plugged or filled longitudinal holes or slots
such as d, of a series of plugged or filled longitudinal slots such as f, substantially as
and for the purposes herein described with reference to the Drawings annexed.
