IMPROVEMENTS IN MACHINERY OR APPARATUS FOR POINTING OR GRINDING HACKLE, GILL, CARD OR OTHER PINS, NEEDLES AND TEETH to be as follows:
Year: 1884

page_text: I JOHN JAMES RICHARDSON of Woodside Horsforth near Leeds in the County of
York, hackle and gill pin manufacturer do hereby declare the nature of said
invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR POINTING OR
GRINDING HACKLE, GILL, CARD OR OTHER PINS, NEEDLES AND TEETH
to be as
follows:-
""
The object of my invention is to grind or point pins, needles and teeth with
greater regularity than hitherto and to be able to correct any defects during the
grinding operation, and these improvements have reference to an invention for
which Letters Patent were granted to me dated 19th January 1870 N° 171.
According to the Specification of the above mentioned patent I place a table of
cast iron on suitable standards and beneath I mount a grindstone having its spindles
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. The roller and plate are so arranged that the position with regard to the
grindstone may be altered by screws levers or other inechanical means. By this
means the wires are brought in contact with the grindstone at any angle.
Now I find it in practice necessary to raise at times the pins clear of the grind-
stone in case of irregularity in the form of the wire or when any of the wires get
crossed in their passage over the stone. In order to effect this according to my
present invention I hinge the table at one side in the framework, and at the opposite
side I provide an adjustable quick threaded screw and lever arrangement whereby
when the grinding operation is not proceeding satisfactorily I am able, without
stopping the machine, to raise the table carrying the pins clear of the grindstone,
and then to rectify any defects.

page_text: I JOHN JAMES RICHARDSON of Woodside Horsforth near Leeds in the County of
York hackle and gill pin manufacturer do hereby declare the nature of my said
Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR POINTING OR
GRINDING HACKLE GILL CARD OR OTHER PINS NEEDLES AND TEETH" and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement, reference being had to the accompanying drawing
and to the letters and marks thereon.
The object of my invention is to grind or point pins needles and teeth with
greater regularity than hitherto and to be able to correct any defects during the
grinding operation and these improvements have reference to an invention for which
Letters Patent were granted to me dated 19th January 1870 N° 171.
According to the specification of the above mentioned patent I place a table of
cast iron on suitable standards and beneath 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. The roller and plate are so arranged that the position with regard to the
grindstone may be altered by screws levers or other mechanical means. By this
means the wires are brought in contact with the grindstone at any angle.
Now I find in practice that it is necessary to raise at times the pins clear of the
grindstone in case of irregularity in the form of the wire or when any of the wires
get crossed in their passage over the stone. In order to effect this according to my
present invention I binge the table at one side in the framework and at the opposite
side I provide a quick threaded screw and lever arrangement, whereby when the
grinding operation is not proceeding satisfactorily I am able without stopping the
machine to raise the table carrying the pins clear of the grindstone, and then to
rectify any defects.
And in Order that my Invention may be more completely understood reference is
given to the accompanying drawings and to the letters and marks thereon.
DESCRIPTION OF DRAWINGS.
Fig 1 is a plan looking at the top Fig 2 is a front and Fig 3 is a back elevation
of a portion of a machine for pointing hackle gill card or other pins needles and
teeth to which my Improvements are applied.
a is a table of cast iron placed on the standards b. Beneath I mount the
grindstone c baving its spindle working in adjustable bearings sliding between the
guides d. A hole is provided in the table through which a portion of the grindstone
may project (see cc Fig 1) above the surface the table. a. On the table a is
mounted a friction roller and plate, the plate being dished out to suit the radius of
the friction roller. The roller and plate are so arranged that the position with
regard to the grindstone c may be altered by screws or other mechanical means
whereby the wires are brought into contact with the grindstone c at any angle.
Now I find in practice that it is necessary to raise at times the pins clear of the
grindstone c in case of irregularity in the form of the wire or when any of the wires
get crossed in their passage over the stone. In order to effect this according to my
present invention I hinge the table a at one side in the framework or standards b

page_text: as shewn at e Figs 1 and 3 and at the opposite side I provide the quick threaded
screw which may be rotated by the lever g. The screw f works in a nut i let in
and attached to the table a. When the grinding operation is not proceeding
satisfactorily I am able by moving the lever g-and without stopping the machine
to raise the table a carrying the pins clear of the grindstone c and then to rectify
the defects.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
The hinged table a, the quick threaded screw f, nut i, and hand lever g all
arranged and operated substantially as and for the purpose herein set forth.
Dated this Eleventh day of November 1884.
