page_text: LETTERS PATENT to Richard Walton and Francis Appleby Stansfield both of
Rawtenstall in the County of Lancaster. for an Invention of "IMPROVED
APPARATUS FOR POINTING OR SHARPENING PICKS OR OTHER TOOLS USED BY
QUARRYMEN MASONS AND OTHER OPERATIVES.”
PROVISIONAL SPECIFICATION left by the said Richard Walton and Francis
Appleby Stansfield at the Office of the Commissioners of Patents on the
2nd February 1883.
RICHARD WALTON and FRANCIS APPLEBY STANSFIELD both of Rawtenstall in
the County of Lancaster "IMPROVED APPARATUS FOR POINTING OR SHARPENING
PICKS OR OTHER TOOLS USED BY QUARRYMEN MASONS AND OTHER. OPERATIVES
"
The object of this invention is to enable picks, such as are used by quarrymen
and miners, chisels used by masons, and other similar tools to be pointed or
sharpened by means of any of the known forging or stamping machines, such for
instance as the machine known as "Ryders" which was patented in the year 1841
No 8835. or any other analogous machine.
The invention consists principally in a peculiar construction of the blocks, dies
or stamps to be attached to the top and bottom punch bars of such machines to
effect the desired object.
We form these blocks with a suitable tang whereby to connect to the punch
bars in the usual manner, and we make the faces of the two blocks so as to incline
towards each other at such an angle as will suit the form of the point desired to be
given to the pick or other tool; and we regulate the relative position of the two
blocks, and the throw of the excentric or cam which actuates the punch bars, in.
such a manner that the two can only just touch at their extreme backward edges.
And to prevent the possibility of pushing the point of the pick or other tool too
far between the blocks, we attach to the back of one of the blocks (the upper one
by preference) a vertical plate, or we form it with a lip or projecting flange,
working against the back of the other block so as to form a stop for the point of
the pick or other tool, and by these means the point of the tool may be drawn or
forged to an exact point, either four sided or rounded in section or a chisel or other
similar tool may be forged to an exact edge, and sharpened to any required angle.

by the said Richard Walton and Francis Appleby Stansfield in the Great Seal
Patent Office on the 1st August 1883.
RICHARD WALTON and FRANCIS APPLEBY STANSFIELD both of Rawtenstall in
the County of Lancaster "IMPROVED APPARATUS FOR POINTING OR SHARPENING
PICKS OR OTHER TOOLS USED BY QUARRYMEN, MASONS AND OTHER OPERATIVES
The object of this invention is to enable picks, such as are used by quarrymen
and miners, chisels used by masons, and other similar tools to be pointed or
sharpened by means of any of the known forging or stamping machines, such for
instance as the machine known as "Ryders" which was patented in the year 1841
N° 8835 or any other analogous machine.
Such being the nature and object of our said Invention we will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect, and in order that the same may be clearly understood
we have annexed hereunto a sheet of drawings illustrative thereof and have marked
the same with figures and letters of reference corresponding with those in the
following explanation thereof
This invention consists principally in a peculiar construction of the blocks, dies
or stamps to be attached to the top and bottom punch bars of such machines to
effect the desired object.
We form these blocks with a suitable tang whereby to connect them to the
punch bars in the usual manner, and we make the faces of the two blocks so as to
incline towards each other at such an angle as will suit the form of the point
desired to be given to the pick or other tool as shown at a, a-b, b in the elevation
Fig. 1 on the drawing and we regulate the relative position of the blocks, and the
throw of the excentric or cam which actuates the punch bars in such a manner that
the two can only just touch at their extreme backward edges as shown at Fig. 1.
And to prevent the posibility of pushing the point of the pick or other tool too
far between the blocks, we attach to the back of one of the blocks (the upper one
by preference) a vertical plate c, c or we form it with a lip or projecting flange,
working against the back of the other block so as to form a stop for the point of
the pick or other tool and by these means the point of the tool may be drawn or
forged to an exact point, either four sided or rounded in section
For square pointed picks or other similar instruments we sometimes form the
tool with an angular notch as shown in front view at Fig. 2 and underneath plan
view at Fig. 3.
For masons chisels and other flat instruments we prefer to make the tools with
a wide recess or notch d, d at each side (see Front view Fig. 5 and two side views
Figs 4 and 6.)
"
The chisels or other tools are brought to the required width by being held on
edge in either of the side recesses à d and are then laid flat and their ends
sharpened in either of the central narrow openings e, c. In this case in place of
the plate c, c (Fig. 1) we employ a tongue and recess f, f as shown at Figs 4 and 6.
For "
pitching tools or other similar instruments requiring a blunt bevilled end,
we form the tools as shown at g. g Fig. 7. and we arrange the throw of the machine
so that the two surfaces g g do not approach each other nearer than the desired
thickness of the end of the tool, and in place of the plate c, c we employ a revolving
steel roller h, h having its edge cut like a fine file which brings the end of the tool
to the required obtuse angular form.
Having now described the nature and object of our said Invention together with

page_text: the manner in which the same is to be or may be performed or carried into
practical effect we wish it to be understood that we claim as our invention.
The novel construction of blocks, dies, or stamps for pointing or sharpening
picks or other tools as herein before described and illustrated by the drawings
annexed.
And Secondly we claim the use of such blocks, dies, or stamps in combination
with a forging or stamping machine substantially in the manner and for the
purposes above more particularly set forth.
In witness whereof I the said Richard Walton (on behalf of myself and the
said Francis Appleby Stansfield) have hereunto set my hand and seal this
thirtieth day of July in the year of our Lord one thousand eight hundred and
eighty three
