PROVISIONAL SPECIFICATION.
Improvements in Metal Rolling and in Apparatus therefor.
We, JOSEPH JUSTE and JOANNY BURLAT of Montverdun (Loire) in the
Republic of France, Nail and Tack Manufacturers, do hereby declare the nature of
this invention to be as follows:-
The process forming the subject of this invention enables nails and other similar
articles and tools to be made and finished in one single operation. For this purpose
we employ a rolling mill with three or four rollers the diameter of which may be
varied according to the length, the shape, and the number of the articles to be
turned out during one revolution of the rollers. By employing four rollers with
their peripheries partly bevelled, square or rectangular rods may be obtained,
provided the bevels of the cylinders are straight. These bevels may be of any
suitable shape the rods rolled out by them being of the corresponding shape in each
case. Where only three rollers are employed rods of triangular section may be
made, the exact shape varying according to that of the bevels. The rollers may
be recessed, so that the metal rolled between them will be less compressed when
operated on by the recessed parts than when operated on by the remaining parts.
It will therefore present projections corresponding in shape and size to the said
recesses. The transition from a projecting to a recessed portion need not be sharp
or abrupt, but may be gradual and varying by almost unnoticeable degrees. The
rolled bar or rod will in consequence vary in thickness in different parts of its length,
and may even, if desired, be cut or broken off by simply reducing its thickness
to zero.
It will thus be seen that nails or tacks of any section and rods of any desired
shape and size, as well as other articles and tools, such as square, rectangular,
triangular, circular, and semicircular files, tapering towards the end in the usual
way, may be obtained at one stroke. The cylinders or rollers act by compression
and the pressure of all of them being exercised on the same point, the metal is
compressed and shaped without being damaged. The rollers may be either
stationary or adjustable in all directions, but must be arranged so that the edges
will not be chipped in the act of moving them closer together or farther apart.
The bevelled projections of each roller are arranged so as to intersect internally
The rollers are
which enables them to grip the metal securely whatever its size.
each mounted upon a spindle and against a carrier or disc which enables them to be
changed at will according to the nature of the articles to be obtained.

We, JOSEPH JUSTE and JOANNY BURLAT of Montverdun (Loire) in the
Republic of France, Nail and Tack Manufacturers, 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 :-

their peripheries partly bevelled, square or rectangular rods may be obtained,
provided the bevels B of the rollers are straight as shown in the accompanying
drawing. These bevels may be of any suitable shape the rods rolled out by them
being of the corresponding shape in each case. Where only three rollers are
employed rods of triangular section may be made, the exact shape varying according
to that of the bevels. The rollers may be recessed as at E so that the metal rolled
between them will be less compressed when operated on by the recessed parts than
when operated on by the remaining parts. It will therefore present projections
corresponding in shape and size to the said recesses E. The transition from a
projecting to a recessed portion need not be sharp or abrupt, but may be gradual
and varying by almost unnoticeable degrees. The rolled bar or rod will in conse-
quence vary in thickness in different parts of its length, and may even, if desired,
be cut or broken off by simply reducing its thickness to zero.
It will thus be seen that nails or tacks of any section and rods of any desired
shape and size, as well as other articles and tools, such as square, rectangular,
triangular, circular, and semicircular files, tapering towards the end in the usual
way, may be obtained at one stroke. The cylinders or rollers act by compression
and the pressure of all of them being exercised on the same point, the metal is
compressed and shaped without being damaged. The rollers may be either
stationary or adjustable in all directions, but must be arranged so that the edges
will not be chipped in the act of moving them closer together or farther apart.
The bevelled projections of the rollers are arranged so as to intersect internally
which enables them to grip the metal securely whatever its size. The rollers are
each mounted upon a spindle C as shown in the drawing and against a carrier or
disc D which enables them to be changed at will according to the nature of the
articles to be obtained.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. The manufacture of nails tacks pins and other metallic articles by rolling in
the manner substantially as described.
2. In apparatus for manufacturing nails tacks pins and other metallic articles the
employment of three or more rollers such as A substantially as described and illus-
trated in the accompanying drawings.
3. The method of making nails tacks pins and other metallic articles by means of
overlapping rollers substantially as described and illustrated in the accompanying
drawings.
