Improvements in Machinery for the Manufacture of Horse Shoe Nails.
JAMES SWALWELL, 29, Godfrey Road, Newport, Mon., Manager of Works, do
hereby declare the nature of this invention to be as follows:-
My invention consists of machinery for punching and shearing blanks for horse
shoe nails then controlling and delivering them head downwards to the first pair of
rolls in any of that well known class of machinery for making horse shoe nails
from blanks punched or sheared from a nail strip of the proper section fed into the
machine by hand or mechanically but with the breadth of the nail strip in a
vertical plane.
The object of this invention is to provide machinery for punching out one blank
into a guide way through which it drops head downwards to the rolls, and at the
same time to shear another blank from the end of the plate with its head upwards
held between two dies or shears shaped on their faces to correspond with the
shape of the nail strip and on their backs semi circular.
These two shears are fitted in a presser block which is held up by a spring
against a stop which allows the presser block to rise until the face of the bottom
shear is in line with the top face of the punching dies and the other so much
above as to allow the strip to be fed forward between the faces of the two shears up
to a stop which is fitted between them to form a guage which can be regulated
to suit the width of blanks to be cut. When the plate end reaches this stop pres-
sure is put upon the top shear through a block carried by the punching slide this
forces the shears and presser block down cutting of the blank whilst held between
the faces of the shears. After the blank is severed the shears are turned half
a revolution carrying the blank between their faces. This brings the head part
of blank downwards over a guide way through which it drops to the rolls, when
the strip can be fed forward for the next blank. With the exception of the first
few blanks which are punched out before the strip reaches the stop between the
shears two blanks are cut at each stroke one punched and the other sheared then
passed head downwards in separate guide ways to the rolls which are provided
with separate passes of the required form to receive them.
In applying my invention to a machine for punching and shearing blanks for
nails to be finished in a separate machine I use one or more sets of the punching
and shearing tools each set punching one blank and shearing the other as herein-
before described.

JAMES SWALWELL, 29, Godfrey Road, Newport, Mon., Manager of Works, 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: -
My invention consists of machinery for punching and shearing blanks for horse
shoe nails then controlling and delivering them head downwards to the first pair of
rolls in any of that well known class of machinery for making horse shoe nails
from blanks punched or sheared from a nail strip of the proper section fed into the
machine by hand or mechanically but with the breadth of the nail strip in a
vertical plane.
The object of this invention is to provide machinery for punching out one blank
into a guide way through which it drops head downwards to the rolls and at the
same time to shear another blank from the end of the plate with its head upwards
held between two dies or shears shaped on their faces to correspond with the
shape of the nail strip and on their backs semi circular.
These two shears are fitted in a presser block which is held by a spring against
a stop which allows the presser block to move until the face of the right shear is
in line with the face. of the punching dies and the other so much away from
it as to allow the strip to be fed forward between the faces of the shears and up
to a stop plate which is fitted between them to form a gauge which can be regu-
lated to suit width of blank to be cut.
When the plate end reaches this stop pressure is put upon the left shear through
a block carried by the punching slide this forces the shears and presser block to
the right cutting off the blank whilst held between the faces of the shears. After
the blank is severed the shears are turned half a revolution carrying the blank
between their faces this brings the head part of blank downwards over a guide
way through which it drops to the rolls when the strip can be fed forward for the
next blank.
With the exception of the first few blanks which are punched out before the end
of strip reaches the stop between the shears two blanks are cut at each stroke one
punched and the other sheared then passed head downwards in separate guide
ways to the rolls which are provided with separate passes to receive them.
In applying my invention to a machine for punching and shearing blanks for
nails to be finished in a separate machine I use one or more sets of the punching
and shearing tools each set punching one blank and shearing the other as herein-
before described.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is to be performed.
Fig. 1 represents in front elevation that part of a nail machine to which my
improvements are applied. Fig. 2 is a horizontal section through same. Fig. 3
is a side elevation partly in section shewing face of dies guideway and turn over
gear.
Figs. 4, 5, 6, 7 and 8 are drawn to a larger scale to shew the parts representing
my improvements the same letters of reference indicate the same parts in the
several figures of the drawing.
6 Fig. 8 is the nail strip shewing the end with the first blanks punched out
singly the line through the thick part of strip shews where the first blank is 10
be sheared off with its head uppermost and the dotted lines show the blank that is
to be punched simultaneously with its head downwards

The operation is as follows the end of the nail strip 6 is fed forward between
the shears cc which are kept apart by springs r, to allow the plate to pass freely
between them up to the stop h, when the slide ; carrying the block i, and the
punch moves forward the punch / cutting out the blank through the dies g g,
with its head downwards which then drops direct through a guideway a, to the
rolls k, and the block i forcing forward the shears c c in the presser block d, shears
off the blank with its head upwards held between the faces of the shears cc when
the slide on its return stroke allows the spring e to force the presser block d up
to the stop f, the two cutters c c are turned half a revolution carrying the blank
with them this brings the blank with its head downwards over the guideway a,
through which it drops to the rolls k, the turning is effected by the catch plate n,
chain wheels ( & P and the spindle q, one end of which is fitted between the outer
end of shears cc, the catch plate n, is turned a quarter revolution on each out
stroke of slide J by the catch rod S. This turns the spindle y and the shears cc
q
half a revolution the chain wheels & P being geared suitably to effect this.
When the blank which has been turned over in the shears c'c drops into the
guideway a, the plate is fed forward for the next two blanks to be cut and so on
through the length of the plate.
The guideways a a, Fig. 3 are shewn to deliver the blanks to one separate line of
passes in the rolls but may be varied to deliver through two distinct vertical guide-
ways to two separate lines of passes as hereinbefore described.
The arrangement and combination of the parts forming my improvements are
shewn in Fig. 4, with a nail plate fed up to the stop h in position to have one
blank punched out by the punch 7 and the other sheared off by the shear c.
Having now particularly described and ascertained the nature of my inven
tion and the manner in which the same is to be performed I declare that what I
claim is:-
Two semi circular shears with a stop plate between them to act as a guage and
fitted in a presser block free to be turned and working in combination with the
dies and punch substantially as and for the purposes hereinbefore described and
illustrated by the accompanying drawings.
