PROVISIONAL SPECIFICATION.
Improvements in Machinery for Forming Wire Nails for Boots
and Shoes.
I JONATHAN BOOTHMAN of Hazelhurst near Rochdale in the County of
Lancaster, Boot Manufacturer, do hereby declare the nature of this invention to be
as follows:
My said invention relates to improvements in the machine for making nails
from a continuous length of wire, and for driving such nails in the manufacture
of boots and shoes, as described in the Patent Specification of H. H. Lake No. 36
A:D. 1881.
In the machine described as aforesaid the points of the nails are formed taper
and severed by the action of a pair of cutters, contained in suitable holders, one of
which is fixed, while the other oscillates horizontally about a vertical axis, so that
the cutter moves through an arc of a circle, the cutters themselves being curved to
correspond. In the said machine the fixed cutter is outside and nearest the article
being operated upon and the faces are inclined in such a manner that the slant of
the taper point is downwards and towards the exterior of the work being operated
upon the result is that the tendency of the nail being driven is to protrude
outwards.
According to my said invention I substitute for the curvilinear motion of the
cutters a rectilinear motion, and operate the moving cutter holder horizontally in
suitable straight guides. I make the cutters themselves with plane instead of
curved faces, and so dispose the cutters that the moving or sliding cutter is outside
and nearest to the article being nailed. The inclined surfaces of the cutters are so
arranged that the slant of the taper point is downwards and towards the interior
of the article being nailed, so that the tendency of the nail when driven is to
deviate towards the interior of the article, instead of to the outside. A side lever
and compound links are provided for actuating the moving cutter holder, and means
such as adjustable excentrics are provided for setting the cutters to the proper
traverse.

Improvements in Machinery for Forming Wire Nails for Boots
and Shoes.
I JONATHAN BOOTHMAN No. 3 Oak Villa, Brideoak Street Cheetham
Manchester late of Hazelhurst near Rochdale in the County of Lancaster, Boot
Manufacturer, do hereby declare the nature of this invention and in what manuer
the same is to be performed to be particularly described and ascertained in and by
the following statement and accompanying drawings :-
My said invention relates to improvements in the machine for making nails
from a continuous length of wire, and for driving such nails in the manufacture
of boots and shoes, as described in the Patent Specification of H. H. Lake No. 36
A.D. 1881, hereinafter referred to as Lake's Specification.

page_text: In the machine described as aforesaid the points of the nails are formed taper
and severed by the action of a pair of cutters, contained in suitable holders, one of
which is fixed, while the other oscillates horizontally about a vertical axis, so that
the cutter moves through an arc of a circle, the cutters themselves being curved
to correspond. In the said machine the fixed cutter is outside and nearest the
article being operated upon and the faces are inclined in such a manner that the
slant of the taper point is downwards and towards the exterior of the work being
operated upon; the result is that the tendency of the nail being driven is to
protrude outwards.
Figure 5 of the accompanying drawings shows a nail in the act of being driven
in such a machine. The tendency of the nail is to deviate outwards in the
direction of the arrow.
The remaining Figures 1 to 4 illustrate my said invention (according to which
1 substitute for the curvilinear motion of the cutters a rectilinear motion and
operate the moving cutter holder horizontally in suitable straight guides).
Figure I is a front elevation of that part of the machine in which the nails are
formed and driven.
Figure 2 is a sectional plan through X X of Figure 1.
Figure 3 is a sectional elevation through Y Y of Figure 1.
The remaining parts of the machine are as shown in Lake's Specification.
In the said figures a is the sliding cutter holder carrying a cutter b. At b' is the
fixed cutter secured in the body of the machine and having two grooves in one of
which the point of the nail is formed and through which the waste drops. The formed
nail is severed by the horizontal motion of the cutter (as fully set forth in Lake's
Specification) from the length of wire and is driven through the groove c' in the
usual manner.
A side lever d pivoted at d¹ to a bracket e fixed to or forming part of the
machine is operated by a roller at one end taking into the cam described in Lake's
Specification. At d' the lever is hinged to an excentric e carried by the links ff
to which the cutter holder a is pivoted at f'. By this means a reciprocating
motion is imparted to the cutter holder a which slides in guideways formed in
the machine at g. The cutters 6 b² are formed with plane instead of curved faces
and are so arranged that the moving cutter is outside and nearest to the article
being nailed. The adjacent surfaces of the cutters are inclined so that the slant
of the taper point is downwards and outwards. The advantage of this arrangement
is that the tendency of the nail when driven into the leather is to deviate towards
the interior of the article instead of to the outside as illustrated in Figure 4. The
object of the excentric e is to enable the position and the traverse of the sliding
cutter holder a to be regulated by turning the excentric on its journals in the
links f. When the excentric has been set to the desired position it is secured by
the set screw k.
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. In a machine for forming taper nails by cutting them from a continuous
length of wire the combination of a fixed cutter and a sliding cutter working in a
rectilinear path substantially as and for the purpose herein before described and set
forth.
2. In a machine as described the combination of the side lever d the excentric
pivot d the links f and a horizontally reciprocating cutter holder a substantially
as and for the purpose hereinbefore described and shown.
3. In a machine for cutting and driving nails from a continuous length of wire
the use combination and arrangement of a sliding cutter nearest the work and a
fixed cutter whose inclines are such that the taper point of the nail is presented

page_text: to the article being operated with the tapered face towards the article so that the
tendency of the nail when being driven is to deviate away from the edge
substantially as set forth.
