Lancaster, Cotton Spinner, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR GRINDING CARDS OF CARDING ENGINES."
Sealed the 27th March 1866, and dated the 30th September 1865. --
PROVISIONAL SPECIFICATION left by the said Samuel Faulkner at
the Office of the Commissioners of Patents, with his Petition, on the
30th September 1865.
I, SAMUEL FAULKNER, of Blackley, in the County of Lancaster, Cotton
Spinner, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR GRINDING CARDS OF CARDING ENGINES," to be as
follows:-
My Invention relates to apparatus for grinding cards in which a roller
acting along the whole length of the surface to be ground is employed. This
roller I construct of light iron, and cover it with leather, which, after it has
been ground-true is coated with shell-lac varnish, and upon that is applied a
film of emery. To the grinding roller I impart a traversing motion during. its
rotation, and this I-effect by means of a disc placed at an angle to its axis,.
and constituting therefore a cam to act by its surface against the grinding
roller, which is kept in contact with the said cam by a spring...

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
FAULKNER, of Blackley, in the County of Lancaster, Cotton Spinner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the Thirtieth day of September, One thousand eight
hundred and sixty-five, in the twenty-ninth year of Her reign, did, for
Hérself, Her heirs and successors, give and grant unto me, the said
Samuel Faulkner, Her special license that I, the said Samuel Faulkner,
my executors, administrators, and assigns, or such others as I, the said
Samuel Faulkner, my executors, -administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUS FOR GRINDING CARDS OF CARDING ENGINES," upon the condition
(amongst others) that I, the said Samuel Faulkner, by an instrument in
writing under my hand and seal, should particularly described describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.
:
.. NOW KNOW YE, that I, the said, Samuel Faulkner, do hereby declare
the nature of.my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following.
statement and accompanying Drawing, that is to say :-
My Invention relates to apparatus for grinding cards in which a roller
acting along the whole length of the surface to be ground is employed. This
roller. I construct of light iron, and cover it with leather, which after it has
been ground true is coated with shell-lac varnish, and upon that is applied a
film of emery. To the grinding roller I impart a traversing motion during.
its rotation, and this. I effect by means of a disc placed at an angle to its.
axis, and constituting therefore a cam to act by its surface against the
grinding roller, which is kept in contact with the said cam by a spring.
The accompanying Drawing represents a grinding roller constructed
according to my Invention in longitudinal section, and also my improved

page_text: method of imparting the traversing motion thereto during the operation of
grinding.
:
In the first place I will describe the method of constructing the said roller.
The axis is at a, it-being of light metal, such gas as tubing, upon this are
mounted three bosses 6 carrying rings c, around which is lapped sheet iron d
which forms the foundation of the roller. This sheet iron I form in twó
parts, meeting at the centre of the roller upon the middle ring c; the ends of
cach piece of iron are rivetted together, and in order to maintain the balance
I cause the lines of rivets of the two sheets to occupy positions opposite to
each other as regards the axis of the roller. The roller being so far formed,
I cover it with old leather fillet e, from which the wire has been drawn, shellac
or other suitable cement being used to cement the leather to the sheet
iron. The axis. of the roller being now placed in a lathe or such like
apparatus, the leather, surface is 'ground or turned by any suitable ordinary
tools or apparatus. In practice I prefer using "Hulines patent grinder,"
and: thus a true surface is obtained, upon which the emery may be placed.
Before, liowever, placing the emery thereon, I give the leather several coats
of shellac varnish, the object of which is to prevent the said leather from
becoming wet when at a future time the emery has to be removed for the
application of a new coating. Before applying the emery warm the roller
at a steam pipe, for the purpose of preventing the glue to be used from
becoming chilled. In order to apply the glue the roller, adapted in suitable
bearings, and provided with a straight edge extending along its length, is
caused to revolve. I then take a long brush, such as is used to brush
cotton out of cylinders, but with long soft bristles, say, 'two inches long, and
fill this with glue, using for that purpose a large paint brush; by resting the
first-mentioned brush upon the straight edge the glue may be applied equally
over the surface of the roller. This I repeat a second time, and if the
operation be properly performed, it will be sufficient for rollers up to 9 or 10
inches diameter. The roller being still caused to revolve, I apply a box
above it provided with a sieve at its bottom, and containing emery. By
working the emery about by hand, or by any convenient mechanical arrange-
ment, it falls through the sieve upon the roller, and covers it equally. The
rotation of the roller should be kept up until the glue is set. The Drawing
also shews the other part of my Invention. Upon the axis a above mentioned
is an arm f, provided with a boss f mounted up a stud h, which carries a
disc i placed at an angle to the said boss. This disc is provided with a
bevilled edge bearing against another bevelled disc k fast upon the axis a.
Upon the boss g is a pully driven from any convenient part of the carding

page_text: engine, and at m is another pulley, by which the grinding roller is caused to
revoke. In order to grind a carding roller the grinding roller is placed in
contact therewith, its axis, being supported by filbows or other bearings, as
at n, or in any other convenient and ordinary manner. The rotation of the
grinding roller is effected through the pulley m, while at the same time the
pulley, and consequently disc i are caused to revolve, and as the said disc is
placed at an angle to its axis it will force; forward the grinding roller against
the tension of a spring o, which spring will subsequently carry back the roller,
and thus a traversing motion will be imparted thereto. The arm f may rest
upon the framework of the carding engine, or may be supported in any other
convenient manner. I prefer so to drive the pulley that the grinding roller
is caused to traverse each way 60 or 70; times in a minute. In order to
secure perfect truth, the roller after having been covered with emery. may be
submitted lightly to such apparatus as "Hulmes' grinder," as, aforesaid,
whereby any little lumps that might otherwise exist are removed.
Having thus described and ascertained the nature of my said Invention,
and the manner in which the same is to be performed, I desire it to be under-
stood that I claim as secured to me under the above in part recited Letters
Patent,
Firstly, constructing such rollers as aforesaid of light iron, and subsequently
covering them, substantially as described.
Secondly, imparting a traversing motion to the roller when grinding by
means of a disc placed at an angle to its axis, as above described.
In witness whereof, I, the said Samuel Faulkner, have hereunto set my
hand and seal, this Twenty-eighth day of March, in the year of our
Lord One thousand eight hundred and sixty-six.
