PROVISIONAL SPECIFICATION left by the said John James Richardson
at the Office of the Commissioners of Patents, with his Petition, on
the 19th January 1870.
I, JOHN JAMES RICHARDSON, of Leeds, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR POINTING OR GRINDING HACKLE, GILL, CARD, OR
OTHER PINS AND TEETH USED IN MACHINERY FOR PREPARING WOOLLEN, COTTON,
FLAX, OR OTHER FIBROUS SUBSTANCES," to be as follows:-
The object is to grind or point pins or teeth of any length or size to
any required angle with more regularity and in greater quantities than:

page_text: by machinery or apparatus hitherto constructed. I place a table of cast
iron or other suitable material on suitable standards, and underneath I
mount a grindstone, having its spindle working in adjustable 'bearings
which may be regulated by screws, levers, or other mechanical means; a
hole is provided in the table, through which a portion of the grindstone
may project above the surface of the table. On the table are mounted a
friction roller and plate, the plate being dished out to suit the radius of
the friction roller. Roller and plate are so arranged that their position
with regard to the grindstone may be altered simultaneously by screw,
lever, or other mechanical, means. By this means the wires are brought
in contact with the grindstone at any required angle. The friction roller
may be of any required width and supplied when necessary with any
required number of rings or flanges, which are cut or divided equally
into any required number of parts or teeth on the periphery, by means
of which the wires are separated and retain their proper angle during
the whole of the operation. The friction roller and plate are faced with
india-rubber or other suitable material. The face of the grindstone is
made concave to suit the radius of the friction roller. The wires are
placed in a receiver or hopper from which they pass between the friction
roller and plate with the end projecting, so as to come. in contact with
the grindstone. A guide or front plate is provided, against the face
of which the ends of the wires are brought, so that they are made
perfectly level with each other, and the same amount of taper is
obtained.

filed by the said John James Richardson in the Great Seal Patent
Office on the 19th July 1870..
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOIN
JAMES RICHARDSON, of Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her. a
Letters Patent, bearing date the Nineteenth day of January, in the
year of our Lord One. thousand eight hundred and seventy, in the
thirty-fourth year of Her reign, did, for Herself, Her heirs and suc-.
cessors, give and grant unto me, the said John James Richardson, Her
special licence that I, the said John James Richardson, my executors,
administrators, and assigns, or such others as I, the said John James

page_text: Richardson, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
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 "IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR POINTING OR GRINDING HACKLE,
GILL, CARD, OR OTHER PINS AND TEETH USED IN MACHINERY FOR PREPARING
WOOLLEN, COTTON, FLAX, OR OTHER FIBROUS SUBSTANCES," upon the condition
(amongst others) that I, the said John James Richardson, my.executors
or administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly 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 Scal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent..
NOW KNOW YE, that I, the said John James Richardson, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement :-
The object is to grind or point pins or teeth of any length or size to
any required angle with more regularity and in greater quantities than
by machinery or apparatus hitherto constructed. I place a table of cast
iron or other suitable material on suitable standards, and underneath I
mount a grindstone, having its spindle working in adjustable bearings,
which may be regulated by screws, levers, or other mechanical means; a
hole is provided in the table, through which a portion of the grindstone
may project above the surface of the table. On the table are mounted
a friction roller and plate, the plate being dished out to suit the radius
of the friction roller. Roller and plate are so arranged that their
position with regard to the grindstone may be altered simultaneously by
screw, lever, or other mechanical means. By this means the wires are
brought in contact with the grindstone at any required angle. The
friction roller may be of any required width, and supplied when
necessary with any required number of rings or flanges, which, are cut
or divided equally into any required number of parts or teeth on the
periphery by means of which the wires are separated and retain their
proper angle during the whole of the operation. The friction roller and
plate are faced with india-rubber or other suitable material. The face of

page_text: the grindstone is made concave to suit the radius of the friction roller.
The wires are placed in a receiver or hopper, from which they pass
between the friction roller and plate, with the end projecting so as to
come in contact with the grindstone. A guide or front plate is provided,
against the face of which the ends of the wires are brought so that they
are made perfectly level with each other, and the same amount of taper
is obtained.
S
And in order that my Invention may be more fully understood I
annex and proceed to describe two Sheets of Drawings, in which Fig. 1
(Sheet 1) represents a side elevation, and Fig. 2 an end elevation; Fig. 3
(Sheet 2) represents a plan of the machine; Figs. 4 and 5 an elevation
and section of friction wheel and plate.
The standards and framework are shewn at a. Within the framework is
a grindstone 6 of any suitable diameter mounted on a shaft in adjustable
bearings or centres c of wood or other suitable material carried by
blocks & fitting in guides in the framework, so that they may be adjusted
by the screws e, having their nuts f fixed in the standards, as shewn.
Above the framework is mounted the table g supported by a stretcher held
between the brackets h, and (when not in operation) by the lever i being
connected thereto by the bracket j with the adjustable nut k and screw ?.
One end of the lever is mounted on a stud m so as to work freely, and is
held in any required position by the plate n fixed on the framework and
retained by the spring o. On the table g are mounted the carriers p
provided with adjustable bushes q; in these are mounted the centres r,
between which is mounted the shaft s, having fixed on it the friction
roller t. The friction roller t, which may be of any required breadth, is
faced with india-rubber or other 'suitable material, as shewn on Sheet 2,
Fig. 5. On the shafts may also be mounted the driving pulley either
separate from the roller or forming a portion of it, as shewn. A hole is
provided in the centre of the table g, into which is fitted the friction
plate u which is formed to suit the radius of the friction roller t. That
portion marked 1 on Sheet 2, Fig. 5, may be of cast iron, but that
marked 2 should be rivetted to it, as shewn, and by preference be made
of iron or steel. This also is faced with india-rubber or other suitable
material, as shewn. The periphery of the grindstone 6 is made concave,
as shewn, to suit the radius of the friction roller t. The friction roller t
is shewn placed at an angle, but this may be varied according to the
style of point required. The table g may also be adjusted for the same

page_text: purpose, a provision for which is made on the brackets h. The set
screws are used to prevent the wire to be operated upon from being
brought too low down. w and x are adjustable guides for the
purpose of
conducting the wire between the friction roller t and plate u, and the
box y receives the wire after being pointed. z serves not only as a
cover for the grindstone 6, but also takes away the dust which passes
through a pipe at the bottom, as shewn by the arrow, and away from
the operator. On the grindstone shaft is mounted a suitable driving
pulley.
The operation is as follows:-The friction roller and plate are brought
down, as shewn in dotted red lines, by the attendant by means of the
lever i. The wire is first placed on the guides w; and set to the required
length against the face of the guide x, then they are allowed to enter
between the friction roller t and plate u, the projecting ends thereby
coming in contact with the grindstone, as shewn, whilst the grindstone
is travelling at a high speed. By passing between friction roller and
plate a rotary motion is given to the wire, thus a perfect point is
produced.
Having now described the nature of my Invention, and the manner in
which the same is to be performed, I do not limit myself to the precise
details herein described and illustrated; but what I do claim is, the
arrangement, construction, and application of machinery or apparatus for
pointing or grinding hackle, gill, card, or other pins and teeth used in
machinery for preparing woollen, cotton, flax, or other fibrous substances,
substantially as herein-before described and illustrated in the accom-
panying Drawings.
In witness whereof, I, the said John James Richardson, have here-
unto set my hand and seal, this Fifteenth day of July, in the year
of our Lord One thousand eight hundred and seventy.
JOHN JAMES RICHARDSON. (L.S.)
