Sections 18 to 21 of the Patents, Designs, and Trade Marks Act, 1883.
We, THOMAS DURRANS, Architect, and EMILY DURRANS, Gentlewoman, both of
19, Alpha Road, Regent's Park, in the County of Middlesex, do hereby declare the
nature of our Invention for "IMPROVEMENTS IN NAILS AND LIKE DEVICES," and in
what manner the same is to be performed, to be particularly described, and
ascertained in and by the following statement:-
This Invention relates to certain improvements in nails, serew nails; and analogous
devices used for fastening and other purposes.
The improved nails, serew nails, or like devices, are especially applicable as means of
fastening for use in joinery, cabinet work, securing floor-boards, and other analogous
purposes where it is of advantage to effect a secure and inexpensive connection of the
parts without the means of fastening being visible, (and for this purpose are intended
to supercede the double ended nails hitherto proposed to be used for such purposes and
the troublesome and more costly method of dowelling the parts together,) and for
use as fence nails and analogous purposes where protection from intrusion is
desired.
The Invention, consists, essentially, in the formation of nails and serew nails,
with one end adapted to be driven or turned into the edge or desired part of the
board or part to be protected or connected, and with an oppositely disposed end
arranged relatively to the firstly referred to end as hereinafter described and adapted for
insertion into the adjacent edge of a board or part to be jointed or connected there-
with or for use in projecting as a means of protection, and with a junction piece or
part connecting such oppositely disposed entering, or entering and protecting ends or
parts adapted or utilizable as hereinafter described over the firstly referred to end of the
nail for use as a head for driving in the nail or turning in the serew, and adapted
on the first entering side under the secondly referred to end of the nail as herein-
after described for entering the board or other part to the level of the top of the
head.
Several modifications of 67'he Invention are is illustrated on the accompanying

page_text: In the modification illustrated in Figs. 1, and, 2, and in Figs. 3, and, 4, which are
views of the nails illustrated in Figs. 1, and, 2, respectively looking in the directions of
the arrows, a, b.
The improved nail is formed with opposite extensions, 1, 2, which are not in line
when viewed transversely, but each of which is tapered or pivotted pointed for facility
of entering or of insertion into the boards or other parts, 3, 4, of wood or other
substance, and with a centre or junction part which at the part, 5, is utilizable adapted
or formed for use as a head for hammering the nail in, and may be slightly flattened
out for this purpose, and is preferably made chisel edged at its first entering end, 6.
The end, 1, is driven into the board, 3, up to the level of the top of the head by
hammering thereon, and the other board, 4, is knocked into position sideways
by the aid of a block of wood and is driven upon the projecting end, 2, of the
nail, vide Fig. 1.
In the modification thereof illustrated in Fig. 2, the first entering end of the nail
is formed as a serew, and its head part, 5, is formed with a slot adapted for-turning
this end of the screw nail into the board or other part in the manner of un ordinary
serew, leaving the part, 2, which may be chisel shaped at, 6×, projecting therefrom;
and upon which the board, 4, is-driven as before stated.
In the modification illustrated in Fig. 3, a screw first entering end, 1, is combined
with a nail-end, 2, as in Fig. 2, but in line therewith, the screw being-turned-inte
position by a suitable-spanner.
These and other modifications in which the extension, 2, is of uneven, or of a
diminishing, as distinguished from an increasing size, reckoning from the central
part or junction piece, are especially applicable for use as invisible or secret nails-or
serew nails and in mailing or serewing joinery, cabinet work; floorboards, and various
other purposes securely and inexpensively without the means of connecting the-parts
being visible.
The same improved nails or serew nails may be used as improved fence nails or for
other like purposes of protection, in such case the parts, 2, would be left projecting
from the board or part, 3, in the manner illustrated in Fig. 4,2 and would effectually
prevent their protective power from being masked by a cack-or-like-means thrown
over them, and which effectually mask the ordinary fence-nails used for protecting
purposes:
Other modifications especially applicable for this purpose are illustrated in Figs.
and, 6, in which the end, is made of un-increasing size, and may be made of a
double, triple, or other multiple formation.
The parts, 1, 2, may be of any desired relative size, length and proportions.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that we
are aware that it has formerly been proposed to make double ended nails, screw nails or
analogous devices with oppositely disposed ends projecting in the same axial line from an
intermediate shoulder or part necessitating the use of a correspondingly formed punch or
instrument for driving the first entering end of such nails into position; and that it has
also been proposed to make double ended nails with oppositely disposed ends projecting in
parallel axial lines from an intermediate part the first entering side of which however is
not in any way specially adapted for entering the part into which it is driven and is
consequently liable to split the same, such nails also being intended to be driven into
position by the use of a correspondingly formed punch or instrument, and that we,
therefore, do not claim such formations of double ended nails but what we claim is :
The herein before described improvements in nails, serew nails, and analogous
devices; the same consisting in the formation thereof with one end adapted to be
driven or turned into the edge or desired part of the board or part to be protected or
connected, and with an oppositely disposed end arranged relatively to the firstly
referred to end as hereinbefore described and adapted for insertion into the adjacent
edge of a board or part to be joined or connected therewith or for use in projecting as
a means of protection, and with a junction piece or part connecting such oppositely

hereinbefore described over the firstly referred to end of the nail for use as a head for
driving in the nail, or turning in the serew, and adapted on the first entering side
under the secondly referred to end of the nail as hereinbefore described for entering the
board or other part to the level of the top of the head, in the improved manner
herein before described with reference to the accompanying drawings.
