France, but at present of 6, Piccadilly, in the County of Middlesex,
Manufacturer, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF NAILS, BOLTS, METALLIC WIRES, AND OTHER SIMILAR MEANS OF
ATTACHEMENT OR CONNECTION."
Sealed the 22nd May 1874, and dated the 28th November 1873.
PROVISIONAL SPECIFICATION left by the said Louis Chelot at the
Office of the Commissioners of Patents, with his Petition, on the
28th November 1873.
I, LOUIS CHELOT, of 56, Rue Montmartre, Paris, France, but at
present of 6, Piccadilly, in the County of Middlesex, Manufacturer, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF NAILS, BOLTS, METALLIC WIRES, AND OTHER SIMILAR MEANS
OF ATTACHEMENT OR CONNECTION," to be as follows :—

page_text: bodies more solid and homogeneous, or for any practical use to which
the principle of my Invention may be applied by grooving them through
a grooved drawing plate parallely to their lenght, so that the nails, bolts,
tacks, rivets, and metallic wires present a polygonal form, the sides or
edges of the groovings forming angles which may be more or less acute
or obtuse, according to the purpose for which the nails, bolts, tacks,
rivets, and metallic wires may be intended. The grooves may be of
various depth, and their number may be also variable, but in practise I
prefer that the groovings be comparatively shallow, and do not exceed
five in number.
The said improved polygonally grooved nails, bolts, tacks, rivets, and
metallic wires are intended to replace the round nails, bolts, tacks,
rivets, and metallic wires, having over them the following important
advantages:-
They present more surface, and consequently greater holding power.
They are more solid.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Chelot in the Great Seal Patent Office on
the 26th May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
CHELOT, of 56, Rue Montmartre, Paris, France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of November, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Louis Chelot, Her special
licence that I, the said Louis Chelot, my executors, administrators,
and assigns, or such others as I, the said Louis Chelot, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend

Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF NAILS, BOLTS, METALLIC WIRES, AND OTHER SIMILAR MEANS OF
ATTACHMENT OR CONNECTION," upon the condition (amongst others) that I,
the said Louis Chelot, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to
be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
:
NOW KNOW YE, that I, the said Louis Chelot, do hereby declare
the nature of the 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 consists in forming nails, bolts, tacks, rivets, metallic
wires for connecting one body to another, or for rendering bodies more
solid and homogenous, or for any other practical use to which the
principle of my Invention may be applied, by grooving them through a
grooving plate parallely to their length, so that the nails, bolts, tacks,
rivets, or metallic wires present a polygonal form, the sides or edges of
the groovings forming angles which may be more or less acute or obtuse,
according to the purpose for which the nails, bolts, tacks, rivets, or
metallic wires may be intended. The grooves may be of various depth,
and their number may be also variable, but in practice I prefer that the
groovings be comparatively shallow, and do not exceed five in number.
The said improved polygonally grooved nails, bolts, tacks, rivets,
metallic wires are destined to replace the round nails, bolts, tacks, rivets,
and metallic wires, having over them the following important advan-
tages
They present more surface, and consequently more holding power.

page_text: Letters Patent, the manufacture of polygonally and parallely grooved
nails, bolts, tacks, rivets, and metallic wires, substantially as above
described.
In witness whereof, I, the said Louis Chelot, have hereunto set
my hand and seal, this 26th day of May, in the year of our Lord!
One thousand eight hundred and seventy-four.
CHELOT, LOUIS. (L.S.)
