An Improvement in Machinery for Rolling Nails, Spikes, and like
Articles.
I, HIRAM EMERY FULLER, of No. 10, High Street, Kensington, in the
County of London, Gentleman, do hereby declare the nature of this invention to
be as follows :-
This invention relates to a machine for making nails, spikes and like articles by
passing a rod or wire between three or four revolving rollers having their
peripheries engraved or otherwise prepared so as to constitute dies by which the
articles are shaped to the desired form. Each of the rollers is made in the form of
a double cone having a common base, the periphery of which may be engraved to
form the die; but, as the dies have to be tempered, are subject to wear, and have
to be changed for different shapes of articles, it is preferred to make them
separately and fix them in grooves formed in the peripheries of the rollers. The
rollers are mounted in bearings in a suitable framing their peripheries meeting
each other, and their shafts are connected by bevil gear so that they all revolve in
the same direction with the same circumferential velocity.

COMPLETE SPECIFICATION.
An Improvement in Machinery for Rolling Nails, Spikes, and like
Articles.
I, HIRAM EMERY FULLER, of No. 10 High Street, Kensington, in the
County of London, Gentleman, do hereby declare the nature of this invention and
in what manner the same is to be performed to be particularly described and
escertained in and by the following statement:-
'
This invention relates to a machine for making nails, spikes and like articles by
passing a rod or wire between three or four revolving rollers having their axes in
the same plane and their peripheries engraved or otherwise prepared so as to
constitute dics by which the articles are shaped to the desired form. Each of the
rollers is made in the form of a double cone having a common base, the periphery
of which may be engraved to form the die; but, as the dies, have to be tempered,
are subject to wear, and have to be changed for different shapes of articles, it is
preferred to make them separately and fix them in grooves formed in the
peripheries of the rollers. The rollers are mounted in bearings in a suitable
framing their peripheries meeting each other, and their shafts are connected by
bevil gear so that they all revolve in the same direction with the safe circum-
ferential velocity.
Fig. 1 of the accompanying drawings is a plan of a machine according to my
invention having three rollers, and Fig. 2 is a half section of one of these with
1

page_text: S' is the main shaft driven by any suitable motor, and driving the first roller R²,
which has on each side of it a bevil wheel W' driving a bevil wheel W' and W on
the one side of each of the other rollers R2 and R. The shaft S' and also the
shafts SS of the other rollers revolve in pairs of bearings B', B' and B' fixed on
the frame F, and the pairs of bearings B' and B' have their bushes made adjustable
by keys K' K' so as to set the rollers R2 R3 up till their edges are in suitable
proximity to each other and to R¹. Each of the rollers is grooved circum-
ferentially to receive the dies D such as are shewn in Fig. 3 which are held in
place by setting screws E.
Although I have shewn three rollers which are adapted to make spikes, nails or
the like of triangular section, obviously four rollers may be similarly constructed
and arranged, adapted to make spikes, nails or the like of approximately
rectangular section.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
A machine for rolling nails spikes and the like by three or four rollers, each in
the form of a double cone having their axes in the same plane and connected to the
athers by bevil gear, substantially as described.
