PROVISIONAL SPECIFICATION left by the said Arthur Alexander Ladislaus
Butler and Alfred Giles at the Office of the Commissioners of Patents on the
28th June 1877.
ARTHUR ALEXANDER LADISLAUS BUTLER, of Balsall Heath, in the County of
Worcester, Manager of Works, and ALFRED GILES, of Birmingham, in the County
of Warwick, Foreman of Works. "IMPROVEMENTS IN APPARATUS USED IN THE
MANUFACTURE OF CAST NAILS AND TACKS."
Our Invention consists of the improvements herein-after described in the appa-
ratus used for making the moulds in which cast nails and tacks are cast, which said
improvements are especially applicable to nails and tacks having fluted or concave
sides, but are also applicable to nails and tacks having plain or unfluted sides, or of
a cylindrical figure..
We will describe our Invention as applied to the manufacture of cast nails.
In the ordinary method of manufacture the prickers by which the part of the
mould is formed in which the shank of the nail is cast are made from steel rods,
circular or square, in cross section. The said steel rods are made of the required
size and shape by filing. Fluted prickers cannot however be made by filing.
In making prickers according to our Invention we employ a holder formed by
jointing together two bars of metal, the jointed bars somewhat resembling a pair of
compasses. In the ends of the bars, and in the axes thereof, holes are made, in
which holes pieces of wire drawn or stamped of a fluted form, or plain or cylindrical,
as required, are inserted. The wires are fixed in the said holes by binding screws.

page_text: The ends of the wires are pointed by filing or grinding, and the said wires have the
figure of the body or shank of the nail to be cast. The ends of the holder constitute
the shoulders or stops, limiting the distance to which the prickers pass through the
plate, by which the part of the mould is formed in which the heads of the nails
are cast.
The jointing together of the bars forming the holder for two prickers may be
applied to prickers of the ordinary kind, that is, prickers made by filing from bars
of square or cylindrical steel. In this case the bars on the ends of which two
prickers are formed are jointed together in the manner herein-before described with
respect to the jointed bars forming the holder; or the joint may be dispensed with,
and the two prickers may be made by filing the ends of one long bar, which is bent
in its middle so as to bring the two prickers parallel to one another.
The jointed or bent. arms of the prickers may be made of wire having the same
section as the stems of the nails to be made, and the shoulders necessary for limiting
the distance to which the prickers enter the sand of the mould may be formed by
slides on the said arms, which slides may be fixed in the required positions by
binding screws.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said Arthur Alexander Ladislaus Butler and Alfred Giles in the Great Seal
Patent Office on the 22nd December 1877.
ARTHUR ALEXANDER LADISLAUS BUTLER, of Balsall Heath, in the County of
Worcester, Manager of Works, and ALFRED GILES, of Birmingham, in the County
of Warwick, Foreman of Works. "IMPROVEMENTS IN APPARATUS USED IN THE
MANUFACTURE OF CAST NAILS AND TACKS."
Our Invention consists of the improvements herein-after described in the appa-
ratus used for making the moulds in which cast nails and tacks are cast, which said
improvements are especially applicable to the manufacture of nails and tacks having
fluted or concave shanks, but are also applicable to the manufacture of nails and
tacks having plain or unfluted shanks, or of a cylindrical figure.
We will describe our Invention as applied to the manufacture of cast nails.
In the ordinary method of manufacture the prickers by which the part of the
mould is formed in which the shank of the nail is cast are made from steel rods,
circular or square, in cross section. The said steel rods are made of the required
size and shape by filing. Fluted prickers cannot however be made by filing.
In making prickers according to our Invention we employ a holder formed by
jointing together two bars of metal, the jointed bars somewhat resembling a pair of
drawing compasses. In the ends of the bars, and in the axes thereof, holes are made,
in which holes pieces of wire drawn or stamped of a fluted form, or plain or cylin-
drical, as required, are inserted. The wires are fixed in the said .holes by binding
screws. The ends of the wires are pointed by filing or grinding, and the said wires
have the figure of the body or shank of the nail to be cast. The ends of the holder
constitute the shoulders or stops, limiting the distance to which the prickers pass
through the false head plate, by which the part of the mould is formed in which the
"
shanks of the nails are cast.
The method of jointing together the bars forming the holder for two prickers may
be applied to the jointing together of rods or wires forming fluted prickers, that is,

page_text: prickers made from rods or wires drawn or otherwise made of a fluted figure. In
this case the fluted rods or wires on the ends of which two prickers are formed are
jointed together in the manner herein-before described with respect to the jointed
bars forming the holder; or the joint may be dispensed with, and the two prickers
may be made by filing the ends of one long bar, which is bent in its middle so as to
bring the two ends constituting the prickers parallel to one another.
The jointed or bent arms of the prickers may be made of wire having the same
section as the stems of the nails to be made, namely, cylindrical, square, or fluted,
and the shoulders necessary for limiting the distance to which the prickers enter the
sand of the mould may be formed by slides on the said arms, which slides may be
fixed in the required positions by binding screws.
. Figure 1 represents in elevation, partly in section, a holder for holding two
prickers, the said holder being made according to our Invention. a, b; are the two
parallel branches of the holder jointed together at c. Axial holes or sockets d, d, are
made in the unjointed ends of the arms a, b, for receiving the prickers e, f. The
arms a, b, of the holders are enlarged at their ends a², 62. Into screwed holes in
these enlarged parts binding screws with milled heads g, h, take. By means of these
screws the prickers e, f, are firmly secured in the holder. The enlarged parts a², b²,
of the holders constitute shoulders which limit the distance to which the prickers
e, f, can pass through the false head plate used in forming the shank half mould for
casting the nails.
The prickers e, f, may either be made of cylindrical, square, or fluted wires or rods,
and are pointed in the usual way by filing or grinding.
The prickers fixed in the holders, Figure 1, are used in the same way as ordinary
prickers.
By unscrewing or loosening the screws g, h, the prickers e, f, may be removed
from the holder and repointed by filing or grinding, and may be afterwards replaced
in the required positions in the holder, and refixed by the screws g, h.
Figure 2 represents in elevation a fluted pricker consisting of two arms or branches
,, jointed together at l.
Figure 4 represents in section on a larger scale one of the fluted arms or branches
i or . m, n, are short cylinders or slides with axial holes, through which holes the
arms i, h, are passed; these short cylinders constitute stops which can be fixed at
any required position on the arms i, k, and fixed there by the bending screws p, q;
these stops limit the distance to which the prickers can be passed through the false
head plate of the mould.
Slides or stops similar to those represented at m, n, Figure 2, may be applied to
prickers, cylindrical or square, in cross section. By the use of these sliding stops
the formation of the shoulders on the prickers ordinarily made by filing are rendered
unnecessary.
Figure 3 represents a pricker inade according to our Invention in which the joint
is dispensed with. This pricker is made froin rods or wires of the required figure,
the rod or wire being bent at its middle r, so as to bring its two halves s, t, parallel
to one another. The ends of the arms s, t, are pointed by filing, and are provided
with sliding stops u, v, and binding screws of the kind described with reference to
Figure 2.
Having now described the nature of our Invention, and the manner in which the
same is to be performed, we wish it to be understood that we claim as our Invention
of improvements in apparatus used in the manufacture of cast nails and tacks,-
First. The new or improved holder for holding prickers, the said holder con-
sisting of two bars jointed together and having axial holes or sockets in their
unjointed ends, in which holes or sockets the prickers may be fixed in the required
positions by binding screws, substantially as herein-before described and illustrated
in Figure 1 of the accompanying Drawing.
Secondly. Constructing prickers having concave fluted sides by jointing together
two fluted rods or wires, the said two rods or wires being pointed and provided
with sliding stops capable of being fixed in the required positions on the rods or

page_text: wires by binding screws, as herein-before described and illustrated in Figure 2 of
the accompanying Drawing.
Thirdly. Making prickers by bending and pointing a rod or wire cylindrical,
square, or fluted, so as to bring its two halves parallel, and provided with sliding
stops capable of being fixed in the required positions on the rods or wires by binding
screws, as herein-before described and illustrated in Figure 3 of the accompanying
Drawing.
Lastly. The use of sliding stops provided with binding screws on prickers formed
of jointed wires of any section.
In witness whereof, we, the said Arthur Alexander Ladislaus Butler and
Alfred Giles, have hereunto set our hands and seals, this Twentieth day of
Décember, in the year of our Lord One thousand eight hundred and seventy-
