PROVISIONAL
SPECIFICATION.
Improvements in Picture Nails.
I, JOSEPH HENRY GREEN of 222 Coventry Road Small Heath, Birmingham,
in the County of Warwick, Dyer & Cleaner do hereby declare the nature of my
said invention to be as follows:-
My invention has for its object: improvements in picture nails and particularly
refers to those with ornamental heads by which they may be readily driven into the
wall without damage to the head of the nail and at the same time may be easily
withdrawn again while the appearance may be considerably improved over the usual
forms of such nails.
In carrying my invention into effect, I form upon the ordinary head a shoulder
formed in one with the nail and this shoulder is stopped off so as to form a groove
which receives the picture cord and outside this groove I project a cap which
prevents the cord from slipping off the groove. This cap is counter-sunk at the
ends and in the centre is a tapped hole which receives a screwed pin formed upon
the loose ornamental head to the nail. Thus, in striking the nail home, the hammer
strikes against the rim formed by the countersinking and the thread of the hole in
the centre cannot thus be damaged. In withdrawing the nail the nippers or wrench
of the hammer would be brought to bear against the solid shoulder which would
assist its removal. The picture cord cannot slip off in case of the ornamental head
coming off as the plain head to the nail prevents it:
[ may form the shoulder and head solid with the nail or I may form them
separately and the configuration and design of the ornamental head may be altered
to any extent without departing from the nature of my said invention.
Dated this 27th day of January 1891.

COMPLETE SPECIFICATION.
Improvements in Picture Nails.
I, JOSEPH HENRY GREEN, of 222 Coventry Road Small Heath, Birmingham
in the County of Warwick, Dyer & Cleaner do hereby declare the nature of my
said 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 has for its object improvements in picture nails and particularly
refers to those with ornamental heads by which they may be readily driven into the
wall without damage to the head of the nail and at the same time may be easily
withdrawn again while the appearance may be considerably improved over the usual
forms of such nails.

formed in one with the nail & this shoulder is stopped off so as to form a groove
which receives the picture cord and outside this groove I project a cap which
prevents the cord from slipping off the groove. This cap is counter-sunk at the end,
and in the centre is a tapped hole which receives a screwed pin formed upon the
loose ornamental head to the nail. Thus in striking the nail home the hammer

the centre cannot thus be damaged. In withdrawing the nail the nippers or wrench
of the hammer would be brought to bear against the solid shoulder which would

coming off as the plain head to the nail prevents it.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which I have fully
illustrated the nature of my said improvements.
Figure 1, is a sectional elevation through the head of the nail showing the orna-
mental head attached.
Figure 2, is a front elevation of the ornamental head.
Figure 3, is a side elevation of a nail in the wall supporting a cord and with the
head detached.
Figure 4, is a side elevation of the head detached.
At the head of the nail A a shoulder is formed in one with the nail in which
shoulder the groove a² is formed to receive the picture cord and beyond this groove
I project the cap a³ thus preventing the cord from slipping off the groove. This
cap is countersunk at the end a* and in the centre a hole is tapped to receive the
screwed pin which is formed upon the loose ornamental head of the nail. Thus
in driving the nail A home the hammer strikes against the surface of the rim a
formed by the countersinking at and the thread of the hole a' in the centre cannot
thus be damaged. In withdrawing the nail the nippers or wrench of the hammer
would be brought to bear against the solid shoulder a which would assist its
removal. The picture cord cannot slip off in case of the ornamental head coming
off as the head a³ to the nail prevents it. The shield is formed upon the head to
ensure the cord D resting in the groove a².
I may form the shoulder a and head a³ solid with the nail A. or I may form them
separately and the configuration and design of the ornamental head B may be
altered to any extent without departing from the nature of my said invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
The improvements in picture nails substantially such as and for the purpose
herein set forth and shewn upon the accompanying drawing.
