PROVISIONAL SPECIFICATION.
An Improvement in Nail Rolling Machines.
I, HIRAM EMERY FULLER, of Leadenhall Buildings, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
In my Specification No. 9513 of 1887 I described a machine for rolling nails in
which one pair of rollers set at right angles to another pair are so arranged that a
wire or rod passed through between the first pair is shaped by them on two of its
sides, and before the part thus shaped leaves these rollers it is caught by the other
pair, and by them shaped on its other two sides, a nail being formed by the double
shaping. For driving these two pairs of rolls as described in my Specification
above referred to I employed worm gearing.
According to my present improvement I substitute for this, toothed gearing
arranged in the following manner.
The main shaft, driven from any suitable motor being parallel to the axes of one
pair of the rollers drives directly by toothed gear the one of these which is directly
geared to the other. The same shaft by a pair of mitre wheels drives a counter-
shaft at right angles and this countershaft being parallel to the axes of the
other pair of rollers directly drives by toothed gear the one of them which is
geared to the other.
Dated this 22nd day of January 1892.

COMPLETE SPECIFICATION.
An Improvement in Nail Rolling Machines.
I, HIRAM EMERY FULLER, of Leadenhall Buildings, in the City of London,
Engineer, 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:-
In my Specification No. 9513 of 1887, I described a machine for rolling nails.in
which one pair of rollers set at right angles to another pair are so arranged that a
wire or rod passed through between the first pair is shaped by them on two of its
sides, and before the part thus shaped leaves these rollers it is caught by the other
pair, and by them shaped on its other two sides, a nail being formed by the double
shaping. For driving these two pairs of rolls, as described in my Specification
above referred to, I employed worm gearing.
According to my present improvement, 1 substitute for this toothed gearing
arranged as shewn by the end view Fig. 1 and the plan Fig. 2 of the accompanying
drawings.
The main shaft A driven from any suitable motor being parallel to the axes B B¹
of one pair of the rollers drives directly by toothed gear the one B of these which
is directly geared to the other B. The same shaft A by a pair of mitre wheels C
drives a countershaft D at right angles, and this countershaft being parallel to the
axes E E of the other pair of rollers directly drives by toothed gear the one of
them E which is geared to the other E'. In my former Specification No. 9513
of 1887 both pairs of the rollers were described as being engraved to operate as
dies or as being provided with removeable dies. In many cases the upper pair
may be made plain so as to serve simply for feeding the wire to the lower pair
which perform the whole work of shaping the nails, separate feeding rolls being thus
dispensed with.

page_text: 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 :-
:
The herein described arrangement of gear for driving two pairs of rollers for
nail rolling in the manner set forth in the Specification No. 9513 of 1887.
Dated this 21st day of October 1887.
