I, JOSEPH PICKLES BINNS of 21 Wolseley Terrace, Battinson Road, Halifax,
Yorkshire, Engineer do hereby declare the nature of my invention for IMPROVED
MACHINERY FOR MANUFACTURING UNTAPPED NUTS INTENDED FOR SCREW BOLTS
to be as follows:-
This Invention has reference to an untapped nut making machine for which
Letters Patent were granted to Philippe Koch N° 3593 bearing date the 13th day
of December 1869.
According to my Invention I insert into an opening made in the framework of
the machine one end of a metal bar the thickness thereof being equal to the depth
of the nut intended to be made.
A vertical plunger is also employed which on rising cuts an oblong length off
the metal bar, and forces it through an oblong die into a slot of an hexagon die
with one open side, the said slot extending through the end. This hexagon die is
then forced by cam or other means against the oblong piece of metal, the said
metal meanwhile resting against a stationary finger, it will thus be seen that as
the hexagon die forces the metal against the finger it will be compressed so us to
fill up the said hexagon die in such manner as to form a blank hexagon nut.
After this the die recedes and removes the nut to a position over a ram which
forces the said nut out of the die to be operated upon, and completed as in the
specification referred to.
Instead of employing an open hexagon die I may employ suitably shaped swages,
which will answer the same purpose.
Hexagon nuts formed in the manner herein described are made without any
waste of metal except what is punched out to form the hole.

I, JOSEPH PICKLES BINNS of 21 Wolseley Torrace, Battinson Road Halifax,
Yorkshire, Engineer do hereby declare the nature of my invention for "IMPROVED
MACHINERY FOR MANUFACTURING UNTAPPED NUTS INTENDED FOR SCREW BOLTS
"
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention has reference to an untapped nut making machine for which
Letters Patent were granted to Philippe Koch bearing date the 13th day of December
A.D. 1869 N° 3593.
This class of machine with my improvements applied thereto is shown in elevation
at Fig. 1, plan view in Fig. 2, end view in Fig. 3 and Fig. 4 gives detail of punching
part of the machine.
In carrying out my invention I make an opening in the framework of the
machine at A. in which to introduce one end of a metal bar A¹ from which is cut a
suitable length of metal for the purpose of being squeezed into the form and shape
of a nut the thickness of such metal bar being equal to the thickness of the nut
intended to be made.
B is a vertical plunger caused to rise and fall at the proper time by means of a
tappit on shaft C which in its rotary motion acts upon the lever D and raises the
plunger thereby, the said plunger being made to descend by a spiral spring a
or cam.
As the plunger rises it cuts an oblong length off the metal bar which it also
forces through an opening in the die E, and into a slot made in the hexagon die F
which die has one side or end open and extending through to the end shown iu
plan view in Fig. 5 and in front elevation Fig. 6, but as the parts work in an
oblique position as shewn in Fig. 2 the slots are not easy to illustrate.
After the oblong piece of metal has been forced into the slot of the hexagon
die F, the said die is forced by means of cam G against the oblong piece of metal in
the direction of the arrow b the said metal meanwhile resting against a stationary
finger H. projecting from the underside of the solid die see Fig. 7.
It will thus be seen that as the hexagon dies advance that the metal would be
crushed and caused to expand sideways, and thus fill up the bexagon die in such
manuer as to form a blank hexagon nut.-After this operation the die recedes and
removes the newly shaped nut to a position shewn at I over a ram J, (see Fig. 3
which forces the said nut out of the die to be operated upon and completed as set
forth and fully described in Koch's specification N° 3593 A.D. 1869.
Instead of employing an open hexagon die I may employ suitably shaped swages
which will answer the same purpose.
Hexagon nuts formed in the manner herein described are made without any
waste of metal except what is punched out to form the hole.

page_text: Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is
Firstly. In a hexagon nut forming machine the use of the sliding die F
having a hexagon space therein in which to force and compress an oblong piece of
metal.
Secondly. The peculiar formation and use of the hexagon and oblong die E and
the hexagon die F for purpose set forth.
