Improvements in Pins and Nails, and in Wire Used for their
Manufacture.
I CHARLES PROVIS of St. Peters Square Emsworth in the County of Hampshire
Ironmonger and Electrician do hereby declare the nature of this invention to be as
follows:-
An ordinary round wire which may be made of any motal or sizo is corrugated
alternately at right angles by any suitable method which preserves a smooth surface
and keeps the sectional area constant (or as nearly constant as may be) throughout
its length. This wire is intended to be used for the manufacture of household pins
hair pins scarf pins hat pins dress pins nails for fastening timber and the liko or if
fonni more convenient to manufacture the pius or nails may be so corrugated after
being made either throughout their whole length or as much of their length as may
seem necessary to provent thoir (in the case of pins) coming out and boing lost. In
the drawing (an enlargement of a household pin) "6" represents "a" turned
round.
Improvements in Pins and Nails, and in Wire Used for their
Manufacture.
I, CHARLES PROVIS The Square Emsworth Hants, 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 :-
An ordinary round wire which may be mado of any metal or size, is corrugated
alternately at right angles by any suitable method which preserves a smooth surface
and keeps the sectional area constant (or as nearly constant as may be) throughout
its length. This wire is intended to be used for the manufacture of household pins,
at pins, lair pins, scarf pins, dress pins, nails for fustening timber and the like; or
if found more convenient to manufacture the pins or nails may be so corrugated after
being inade either throughout their whole length or as much of their longth as my
seem necessary in the case of pins to prevent their coming out and being lost.
In the case of nails it is not important to keep the sectional area constant.
In order that my invention may be fully understood, I will now refer to the
annexed drawings in which :-
Figure 1. is a sido elevation of my invention.
The nail a is provided with the curved or rounded indentations b, which may be
moulded, cut or prossed in the nail, pin or the liko.
By the employment of these curved or rounded indentations the nail has greater

page_text: holding power as when being driven into the wood or other substance the same 13
not cut or injured to the same extent as is the case when sharp or pointed projections
are formed on the nail. Although for purposes of illustration I havo referred to a
nail my invention is equally applicable to pins, hat pins, hair pins, scarf pins, or
dress pins.
It will be seen that the nail may be of uny convenient cross section.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the samo is to be performed 1 declare that what I
cloim is :-
1. A nail, pin, bat pin, hair pin, scarf pin or dress pin, having rounded or curved
indentations or projections moulded cut or pressed in the nail substantially as
described and illustrated and for the purpose set forth.
