PROVISIONAL SPECIFICATION.
Improvements in Forging Steel Pincers and similar Articles.
JOHN DAWSON Tool Manufacturer Bernard Works Park Sheffield do hereby
declare the nature of this invention to be as follows:-
Instead of taking a rod of square iron, and flattening the end intended to form
the jaw to prepare it to receive the steel to be welded upon it, I take a rod of
round or nearly round, steel (at present I think round is the best). After being
heated the said rod is cut down on a sharp edged, but flat boss, about half way, on
one side only, leaving the opposite side full, the lower portion of the said rod, is
then forged into the shape of the handle required to be made, which is then cut off
so as to leave sufficient material to form the jaw, on that portion of the rod which
has been left fully round. The said fully round portion, is then heated, and on
being flattened at right angles to the said cut, will be found to easily spread to a
sufficient width, to form the jaw, which may then be shaped as required, and fitted
together, forming a solid steel article in half the time required to forge one
composed of iron & steel combined.

COMPLETE SPECIFICATION.
Improvements in Forging Steel Pincers and similar Articles.
JOHN DAWSON Bernard Works, Park Sheffield, Tool Manufacturer, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
Instead of taking a rod of square iron, and, after heating, and flattening the end
intended to form the jaw, to prepare it to receive the steel to be welded upon it :
I take a rod of round, or nearly round, or any other section than square, (1 believe
round to be the best) steel, instead of iron. After being heated, the said rod of steel
is cut down, on a sharp edged, but flat boss, on one side only; the hammering
necessary to effect this, forming a flat on the other side. The portion left below
the said cut, is then forged into the shape of the shank required to be made, say as
drawings A or B, and cut off above the flattened portion, at the length required.
The round portion at the top end, is then heated, and on being flattened at right
angles to the aforesaid cut will be found to easily spread to the width and shape
required to form the jaw, which may then be cut off the length required, (see
drawings C & D) and turned round as drawing E, and the holes punched through
to receive the pins, which said pin I make of steel wire, instead of iron which is
usually used.
The two parts are then heated, and fitted together with the aforesaid steel pin
(see drawing F) thus forming a tool of much greater strength, and durability, in
much less time, than is required to forge them under the methods at present
used.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:
1. The method of forging pincers, and similar articles, by means of the aforesaid

page_text: methods, from a rod of steel, instead of from iron with steel welded on the portion
intended to form the jaw.
2. The formation of the jaws of the aforesaid articles, by cutting the rod down or
one side, as in drawings A & B, and afterwards flattening the ends at right angles
to the said cut, as in drawings C & D.
3. The formation of the shanks of the aforesaid articles, by forging the same
froin rods of iron or steel, which are round, nearly round, or sections other than
square, as is now done, the said forging being much easier done than is the case with
square rods.
