IMPROVEMENTS ON PRINTING AND STAMPING PRESSES
Year: 1810

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AUGUSTUS
FREDERICK DE HBINE, of Burr Street, East Smithfield, in the County of
Middlesex, Gentleman, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the First day of February,
in the fiftieth year of His reign, give and grant unto me, the said Augustus
Frederick de Heine, my executors, administrators, and assigns, His special
licence, full power, sole privilege and authority, that I, the said Augustus
Frederick de Heine, my executors, administrators, and assigns, during the
term of years therein mentioned, should and lawfully might make, use, exer-
cise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "IMPROVEMENTS ON PRINTING AND STAMPING PRESSES;"
in which said Letters Patent there is contained a proviso, obliging me, the
said Augustus Frederick de Heine, by an instrument in writing under my
hand and seal, to cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, to be inrolled in
His Majesty's High Court of Chancery within two calendar months after the

page_text: date of the said recited Letters Patent, as in and by the same (relation being
thereunto had) may more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Augustus Frederick de Ileine, do hereby declare that my said Invention is
fully ascertained by the Drawings in the margin, and the following description
thereof, that is to say:-
Instead of applying a screw for my power, I apply two sectors, or a sector
and cylinder, or a sector and roller, to move one against the other by a single
or compound lever.
Figure 1 represents the head of a piston, under which is the plattin or dye;
Figure 2 represents the same in a sido view; in the centro is a hole, in which
the spindle moves by a lever. Figure 3 represents the moveable spindle with
two opposite sectors; Figure 4 is the same in front view. The lever, single
or compound, is fixed to the spindle, as in Figure 5, representing a common
press frame. A is the regulating screw with a male centre B; C, is the
same moveable spindle, Figure 3, on which a single lever is fixed. It is
evident that by bringing the lever from X to Y, as in Figure 6, the piston
will be depressed, as in the common screw, with this difference, that as the
descent of the piston decreases in velocity the power must increase in the
same proportion in the screw; the descent is equal, consequently the power
is equal. This motion may be reversed by putting the opposite sectors at the
top of the piston, and the cylinder or roller on the moving spindle; this will
produce the same effect; or, in case this power is applied to a fly press, it
may be applied by putting the part that acts instead of a screw, like Figure 3
or Figure 4, the part M uppermost through the hole in the head of the press
at B, Figure 5 and 6, and fixing the fly lever above the head of the press,
then by turning the spindle by the fly lover the sectors will act in the manner
of a screw with an increasing power. The sectors and the part which comes
in contact with them must be made of iron, steel, brass, or any other hard
substance. I prefer steel and iron casehardened. The sweep of the sector
and the diameter of the moveable spindle are made as circumstances require,
and can be varied ad infinitum.
In witness whereof, I, the said Augustus Frederick de Heine, have
hereunto set my hand and seal, this Thirtieth day of March, in tho
year of our Lord One thousand eight hundred and ten.
A. DE HEINE. (Ls.)
