Year: 1862

page_text: LETTERS PATENT to John Stanton, of Birmingham, in the County of
Warwick, Engine Fitter, for the Invention of "IMPROVEMENTS IN APPA-
RATUS OR MACHINERY TO BE USED IN STAMPING OR PIERCING METAL WASHERS
AND OTHER SIMILAR ARTICLES."
Sealed the 12th September 1862, and dated the 16th April 1862.
PROVISIONAL SPECIFICATION left by the said John Stanton at the.
Office of the Commissioners of Patents, with his Petition, on the 16th
April 1862.
I, JOHN STANTON, of Birmingham, in the County of Warwick, Engine Fitter,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS OR MACHINERY TO BE USED IN STAMPING OR PIERCING METAL WASHERS
AND OTHER SIMILAR ARTICLES," to be as follows (that is to say):-
My Invention has for its object the manufacture of metal washers and other
similar articles by one operation. To effect this I employ a machine con-
sisting of two punches and their bolsters, the one set at an angle of about sixty
degrees with the other, but in gear with each other; the metal having been
supplied to the first punch a blank is struck out, this blank falls through an
aperture in the bolster, which aperture is provided on one side with an inclined
plane of stout glass or other suitable material, which throws the blank to the
bottom of a receiver below the bolster. In this position the blank is caught
by a grip or catch, which retains it whilst the second punch perforates the

page_text: blank; upon the grip or catch receding the washer falls out of the machine
completed at one operation. The two punches may be geared together to work
reciprocally by a connecting rod and lever, or in any other suitable manner.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Stanton in the Great Seal Patent Office on the 15th
October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
STANTON, of Birmingham, in the County of Warwick, Engine Fitter, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Stanton, Her special license that I, the said John Stanton,
my executors, administrators, and assigns, or such others as I, the said
John Stanton, 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, exer-
cise, and vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPA-
RATUS OR MACHINERY TO BE USED IN STAMPING OR PIERCING METAL WASHERS AND
OTHER SIMILAR ARTICLES," upon the condition (amongst others) that I, the said
John Stanton, by an instrument in writing under my hand and seal, 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 Seal Patent Office within six calendar mouths next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Stanton, 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,
reference being had to the Drawings hereunto annexed, and to the letters
and figures marked thereon (that is to say) :-
My Invention has for its object the manufacture of metal washers and other
similar articles by one operation; to effect this I employ a machine consisting
of two punches and their bolsters, the one set at an angle of about sixty
degrees with the other; but in gear with each other, the metal having been

page_text: supplied to the first punch, a blank is struck out, this blank falls through an
aperture in the bolster, which aperture is provided on one side with an
inclined plane of stout glass or other suitable material, which throws the
blank to the bottom of a receiver below the bolster ; in this position the blank
is caught by a grip or catch, which retains it whilst the second punch perfo-
rates the blank; upon the grip or catch receding, the washer falls out of the
machine completed at one operation. The two punches may be geared
together to work reciprocally by a connecting rod and lever, or in any other
suitable manner.
I will now proceed to give a more detailed description of my Invention by
the aid of the accompanying Drawings, in which Figure 1 represents a side
elevation of the machine, and Figure 2, a plan, as seen from above. (A) shews
the foundation upon which the machine is fixed; (B), the cast-iron frame;
(C, C,) fast and loose pulleys hung on the main shaft, and employed to throw
the machine into or out of gear, steam or other motive power being employed
as may be desirable to work the band over the driving pulley; (D), the fly.
wheel, also hung and keyed on the main shaft or spindle (E), which works in
the plummer blocks (a) fixed on the frame of the machine; (F) is a spur
wheel keyed on the main shaft driving a similar wheel (F), through which
the eccentric and crank shaft (G) is worked, revolving in plummer blocks (a³);
(H) is the crank which works the first or main punch (I), being a joint or
connecting strap attached by a jib and cotter to the crank (H), and by the
links (1, 12,) and centre pins (b) and (c) to the ram of the first punch (Is
the pin (C) acting also as a friction roller; (J) is a slide box, through which
the ram (I³) works, issuing through it at (14), at which end the first or main
punch (K) is fixed, immediately opposite to which is placed the pierced
bolster or die (d) having an aperture through it the size of the blank to be
produced, and which is keyed to an adjustable plate (d*) secured to the frame
of the machine; (L) are set screws by which the position of this plate (d²)
is adjusted. The plate (ds) is also pierced with a similar aperture to that
in the die (d), and it is also furnished with a projecting knib, as at (n),
by which the blank, when it arrives at that point, is tipped over on to its flat
side and dropped down the incline (M), the strippers or fingers (e, e,) upon
the receding motion of the punch (K), clearing the punch of the waste metal;
(M) is a shoot or incline, having its bed or under side lined with glass, metal,
or other suitable smooth material, down which the blank glides into a nozzle
(N), which conducts it into a forked receiver (ƒ), by which it is retained in
position whilst being pierced by the second punch (O). This punch on its
receding motion draws the washer against a second stripper similar to that upon

page_text: the punch (K), when it falls through the hopper (p) on to the floor completed,
and the waste punched from the centre falls to the floor through the opening
(9); the reciprocating action of the second punch is thus gained. A pair
of cranks or eccentrics (h) working in eccentric rings (i) are fitted on
the crank shaft (G), and by their connecting rods (K) and their adjuncts,
they work a lever or rocking bar (P) attached to the machine frame by
the gudgeon (p¹), (Q) being an adjusting screw passing through the cross
head (R), and employed for the purpose of regulating the length of the stroke,
and to compensate for wear and tear; (S) are the connecting links and fric-
tion rollers by which the second punch (0) on the ram (m) is worked by the
lever or rocking bar (P) through the slide box (T), (V) being the die or
pierced bolster belonging to the second punch, having its proper adjusting keys
fixed in the bed plate; (W) is a loose nose piece keyed on to the lever or
rocking bar (P), keeping the punch in its proper direction.
I have now minutely illustrated my Invention in its application to the
manufacture of washers only; it will be evident that by a simple alteration of
the punching or cutting tools in such machines, blanks or forms in metal other
than those used for washers may be as readily produced.
And having thus described the nature of my said Invention, and the manner
in which the same is practically to be carried into effect, I desire further to state
that I do not limit myself to the employment of any of the exact details
herein described or exhibited, as they will admit of modification, but that which
I claim is the general arrangement and combination of the several mechanical
parts or appliances herein described and shewn in Drawings, forming machi-
nery to be employed in punching, stamping, or piercing metal washers
and other similar articles, substantially as herein more fully set forth and
specified.
In witness whereof, I, the said John Stanton, have hereunto set my
band and seal, this Thirteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-two.
JOHN STANTON. (L.S.)
