the County of Middlesex, Lieutenant in the Royal Engineers, for an Invention
of "AN IMPROVED METHOD AND APPARATUS FOR MULTIPLYING COPIES OF

PROVISIONAL SPECIFICATION left by the said Henry Edward Tyler at the
Office of the Commissioners of Patents on the 14th January 1882.
HENRY EDWARD TYLER of Pymme's Park Edmonton in the County of Middlesex,
Lieutenant in the Royal Engineers. "AN IMPROVED METHOD AND APPARATUS FOR
MULTIPLYING COPIES OF MATTER PRINTED BY TYPE WRITERS AND SIMILAR
MACHINES."
•
The type writers and machines of like kind now largely in use serve to produce
only one copy of the matter which they print. My Invention relates to means of
multiplying copies of matter so printed which I effect in the following manner. I
make the types employed in these machines present on their faces numerous points
or chisel edges which when they strike the paper prick holes or make incisions
through it. The paper thus pierced can then be used in the well known manner in
which pierced paper is employed for multiplying copies, ink or pigment being
caused to pass through the perforations of the paper to the surface that is to be
printed on.

I
The type writers and machines of like kind now largely in use serve to produce
only one copy of the matter which they print. My Invention relates to means of
multiplying copies of matter so printed which I effect in the following manner.
make the types employed in these machines present on their faces numerous
chisel edges which when they strike the paper make incisions through it. The
paper thus pierced can then be used in the well known manner in which pierced
paper is employed for multiplying copies, ink or pigment being caused to pass
through the perforations of the paper to the surface that is to be printed on.
↓
In the accompanying Drawings the Figures A, B, C, X, Y, Z, 1, 2, 3, 4, 5 shew
to an enlarged scale face views of one form of the types a section of one of which is
shewn by Fig. 8 the impression part of each of these presenting a number of chisel
edges which cut the paper when the type strikes it.
Having thus described the nature of my Invention and in what manner the
same is to be performed, I claim :-
First. The berein described method of multiplying copies of matter printed by
type writers and similar machines.
Second. The use for type writers or similar machines of types having their
impression part made to present numerous chisel edges substantially as and for the
purpose herein set forth.
In witness whereof I the said Henry Edward Tyler have hereunto set my
hand and seal this Twentieth day of May in the year of our Lord One
thousand, eight hundred and eighty-two.
