PROVISIONAL SPECIFICATION,
Improvements in or connected with Emery Rollers for Grinding Cards
and like Toothed or Spiked Surfaces.
I, JOHN GEORGE BAMFORTHI, of Manchester Road, Slaithwaite, near Hudders-
field, in the County of York, Roller Coverer, do hereby declare the nature of this
invention to be as follows:-
-
This invention relates to emery rollers employed for grinding and sharpening
cards or like toothed or spiked surfaces for opening, working and carding textile
fibres; and the object of my improvements is to adapt such rollers for grinding
the cards or ends of the wires or teeth to natural or needle points.
In carrying out my invention, I first cover the roller with a fabric or other
material or substance of any suitable nature in or to which steel or other suitable
metal wire teeth or pins are secured somewhat in the same manner as cards. The
said foundation is preferably composed of an inexpensive material such as will
serve to hold the wire teeth or pins, these either projecting from the surface at
right angles or at angles corresponding to the teeth of ordinary card clothing.
Over the spiked or toothed covering aforesaid I lay the emery powder which is
built up in the ordinary way to a suitable depth so as to leave the points of the
pins or teeth clear above the surface thereof. The emery roller thus constructed
presents in addition to the emery grinding surface, a series of pointed spikes or
pins spaced at short distances apart, which, in grinding, run between and against
the sides of the teeth of the cards being ground, and thus grind or sharpen the
edges or sides at the same time as the points are ground, thereby giving them
natural or needle points instead of diamond points only.
The said spikes or pins on the emery roller will also serve to clear or open any
obstructed spaces between the points of the wires of the card clothing.
The construction of emery rollers as above described may be varied or modified
as desired, the essential feature of the invention being the studding of the surface
of the roller with steel or like metal points or teeth.

Improvements in or connected with Emery Rollers for Grinding Cards
and like Toothed or Spiked Surfaces.
I, JOHN GEORGE BAMFORTHI, of Manchester Road, Slaithwaite, near Hudders-
field, in the County of York, Roller Coverer, do hereby declare the nature of this
[Price T

page_text: 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 relates to emery rollers employed for grinding and sharpening
cards or like toothed or spiked surfaces for opening, working and carding textile
fibres; and the object of my improvements is to adapt such rollers for grinding
the cards or ends of the wires or teeth, to natural or needle points. In carrying
out my invention I first cover the roller with a fabric or other material or sub-
stance of any suitable nature in or to which steel or other suitable metal wire
teeth or pins are secured somewhat in the same manner as cards. The said foun-
dation is preferably composed of an inexpensive material such as will serve to
hold the wire teeth or pins, these either projecting from the surface at right angles
or at angles corresponding to the teeth of ordinary card clothing. Over the spiked
or toothed covering aforesaid I lay the emery powder which is built up in the
ordinary way to a suitable depth so as to leave the points of the pins or teeth
clear above the surface thereof. The emery roller thus constructed, presents, in
addition to the emery grinding surface, a series of pointed spikes or pins spaced
at short distances apart which, in grinding, run between and against the sides of
the teeth of the cards being ground and thus grind or sharpen the edges or sides
at the same time as the points are ground, thereby giving them natural or needle
points instead of diamond points only.
The said spikes or pins on the surface of the emery roller will serve to clear or
open any obstructed spaces between the points of the wires of the card clothing.
In the accompanying drawings:-
Fig. 1 is cross section of an emery roller for grinding cards and like toothed
or spiked card cloth surfaces, constructed according to my invention.
Fig. 2 is longitudinal elevation of a portion thereof, partly in section, and
Fig. 3 is another cross section of the emery roller, shewing an alternative
arrangement of the spikes or pins.
Referring to the drawings, my invention consists essentially in studding or
providing the emery roller A" with spikes or pointed pins or wires such as
"B" projecting a little beyond the surface of the emery covering "C."
Preferably, the wire spikes or pins "B" are pierced in staple form through a
foundation or base "D" composed of leather, canvas, cloth, or other like suitable
material or substance, in approximately the same manner as the wires are stuck
into the leather or like foundation or filleting in making ordinary card clothing,
this foundation being nailed or otherwise similarly secured to the periphery of the
roller "A" from end to end, as shewn, to attach the spikes or pins "B" thereto.
The said method of attaching the spikes or pins to the roller A" is the one
which I have so far adopted and is, perhaps, the most simple, expeditious and
economical, but I do not confine myself to this, or to any particular method of
attachment, which is a matter of detail not affecting the main feature of my
invention.
An inexpensive material such, say as thick canvas or cloth will serve equally
as well as leather to form the foundation "D," and is, therefore, employed in
preference to leather or filleting to reduce the cost.
After attaching the spiked clothing "D" to the roller, as described, said cloth-
ing is covered with emery powder glued or cemented on and built up, in the same
manner as at present, to the requisite depth or thickness so as to leave the points
or ends of the pins or spikes "B" protruding from the surface of the emery
covering "C."
The emery roller thus constructed presents, in addition to the ordinary emery
grinding surface, a series of projecting pointed spikes or pins spaced at short
distances apart circumferentially and longitudinally which said pointed spikes or
pins, as the roller revolves and reciprocates endwise in grinding card teeth, run
between and are brought against first one side and then the other side of the
teeth of the cards and thus grind or sharpen the edges or sides thereof at the same

page_text: time as the points are ground by the emery surface, thereby giving them natural
or needle points instead of only diamond points as heretofore. The said spikes
or pins "B" will also serve to clear or open any obstructed space or spaces
between the wires of the card clothing.
The wire of which the pins or spikes "B" are made is preferably steel wire,
hardened and tempered, and it may be round in cross section or flat as desired.
Iron wire could be used but it is less durable and not as suitable as steel wire.
The pins or spikes "B" can be bent to an angle somewhat in the same manner
as card teeth are bent, as illustrated in Fig. 1, or they may be straight as shewn
at Fig. 3.
In grinding with the emery roller shewn at Fig. 1, said roller is driven in the
direction indicated by the arrow but for face grinding to reduce the points to one
level or like purposes it is rotated in the reverse direction to that indicated.
The construction of emery rollers as above described may be varied or modified
as desired, the essential feature of the invention being the studding of the surface
of the roller with steel or like metal spikes or pins whose ends or points protrude
or project from the emery covering.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is: -
The application to and combination with emery rollers for grinding card teeth
and the like, of metal spikes or pins suitably attached thereto and spaced at short
distances apart circumferentially and longitudinally the points or ends of said
spikes or pins projecting a little beyond the emery grinding surface substantially
as herein shewn and described and for purposes set forth.
