Brothers of Lindley near Huddersfield in the County of York Card Manu-
facturer for an Invention of IMPROVEMENTS IN ROLLERS EMPLOYED FOR
POINTING GRINDING AND SHARPENING CARDS
31
PROVISIONAL SPECIFICATION left by the said John Sykes at the Office of
the Commissioners of Patents on the 11th September 1882.
JOHN SYKES, of the firm of Messieurs Joseph Sykes Brothers, of Lindley near
Huddersfield, in the County of York, Card Manufacturer, "IMPROVEMENTS IN
ROLLERS EMPLOYED FOR POINTING, GRINDING, AND SHARPENING CARDS,"
This invention relates to an improved roller for grinding pointing and
sharpening cards, the roller consisting of angled and oblique rotating edges or
surfaces.
The roller as above consists of discs angled at their outer edge and composed of
solid emery, or the discs may be made by coating metal or other substance with
emery-tlie discs are secured in an oblique position on their shaft or axis by means
of screw or other like adjustment, or by means of taper washers or taper discs
introduced at the end or between two or more of the said discs, Or the roller may
consist of solid emery having V or angular oblique recesses, and angular or A pro-
jections cut moulded or otherwise formed therein and thereon so as that when.
rotation is imparted to the said roller, its discs or angular projecting edges of the
discs have likewise a to-and-fro motion.
In addition to the motion obtained by reason of the oblique position of the discs
or angular projections the roller may have imparted thereto à lateral to-and-fro
or traversing motion.

by the said John Sykes in the Great Seal Patent Office on the 9th March

JOHN SYKES of the firm of Messeiurs Joseph Sykes Brothers of Lindley near
Huddersfield in the County of York, Card Manufacturer "IMPROVEMENTS IN
ROLLERS EMPLOYED FOR POINTING GRINDING AND SHARPENING CARDS "
This invention relates to an improved roller for grinding pointing and sharpening
cards, the roller consisting of angled and oblique rotating edges or surfaces.
The roller as above consists of discs bevelled or angled at their outer edge and
composed of solid emery or the discs may be made by coating metal or other
substance with emery the discs are secured in an oblique or angular position on
their shaft or axis by means of screw or other like adjustment or by means of
taper washers or taper discs introduced at the end or between two or more of the
said discs. Or the roller may consist of solid emery having oblique angular recesses
and oblique angular or A projections cut, moulded or otherwise formed therein and
thereon so as that when rotation is imparted to the said roller, its oblique discs or
oblique angular projecting edges of the discs have likewise a to and fro or lateral
reciprocating motion.
Such being the nature and object of this my said invention I will now proceed
to describe the same in detail and in order that the invention may be fully under-
stood I have hereunto annexed a sheet of drawings illustrative thereof and have
marked the same with figures of reference, the same letter referring to the same
nart in the several views or figures.
Fig: 2 is an end elevation of same.
Fig 3 is end elevation shewing application to card clothing in strips.
Fig 4 is end elevation shewing application of my improved roller to the
grinding of cards on a card cylinder or cards mounted and in use or ready
for use.
Fig 5 is detail of emery disc
Fig: 6 is elevation of emery disc shewing by dotted lines the change of position
of the disc at each revolution.
A is a central shaft to which is secured the boss B having adjusting screws C.
E is a plate which by means of the screws C is set to an angle and thereby
determines the angle of the emery discs F-J is a taper holding collar, K is
the nut which by means of the shaft A binds and securely holds the whole in
position.
It will be seen that the discs F being set obliquely, or at an angle to the shaft A
rotation will give to the circumference of the several discs at their point of contact
with the cards the reciprocating or to and fro motion so that each disc will act
upon and grind both sides back and point of each card tooth within the compass of
its lateral motion thus effecting the grinding of the teeth by the to and fro lateral
reciprocating motion as distinguished from other rollers or discs in which the angles
or peripheries are at right angles to the axis around which they rotate or of emery
discs at fixed distances in unison with or equal to the spaces or furrows between
the several lines of card teeth.

page_text: It will be understood that the invention above described is specially applicable
to the grinding of cards in use or after the same are "mounted" as and when
requisite.
Having thus fully described the nature and particulars of this my said invention
together with the manner in which the same is to be or may be performed or
carried into practical effect I would have it understood that I lay no claim per se
to the emery disc nor to an emery roller having angular grooves formed therein as
such is not new what I do claim is.
Firstly The improved roller comprising the angular emery discs constructed
arranged and working or rotating obliquely to their axis in manner and for purpose
herein described.
Secondly-The improved roller having the angular oblique recesses and
A projections in manner and for purpose. herein described and as illustrated by
drawings.
In Witness whereof I the said John Sykes have hereunto set my hand and
seal this twenty fifth day of January in the year of our Lord one thousand
eight hundred and eighty three.
JOHN SYKES. (L.S:)
