A NEW OR IMPROVED RIVET SCREW OR FASTENING
Year: 1873

page_text: LETTERS PATENT to Samuel Sidney Bromhead, of Southsea, in the
County of Hants, for the Invention of "A NEW OR IMPROVED RIVET
SCREW OR FASTENING."
Sealed the 2nd April 1874, and dated the 6th October 1873.
PROVISIONAL SPECIFICATION left by the said Samuel Sidney Brom-
head at the Office of the Commissioners of Patents, with his
Petition, on the 6th October 1873.
I, SAMUEL SIDNEY BROMHEAD, of Southsea, in the County of Hants,
do hereby declare the nature of the said Invention for "A NEW OR
IMPROVED RIVET SCREW OR FASTENING," to be as follows:-
My Invention of an improved rivet screw or fastening consists of
manufacturing such rivets, screws, or fastenings of zinc wire after it has
been well annealed, so as to become perfectly malleable. The zinc wire
when annealed is converted into rivets, screws, or fastenings by any
ordinary machine or process, and are then ready for use without any

page_text: further preparation, thereby saving the cost of tinning or galvanizing;
and, as in the case of copper, being cheaper than the simple material,
while obtaining a better result.
Hitherto there has been much difficulty in joining some articles
together by means of rivets or screws capable of resisting corrosion and
oxidation. To try and meet this difficulty rivets and screws have been
manufactured of iron, and also of copper, and afterwards galvanized or
tinned, but these are expensive methods, and only partially successful,
because in the course of time the coating becomes removed, and the
rivets or screws corrode or oxidize.
1.
I also manufacture of annealed zinc for similar purposes split rivets,
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Sidney Bromhead in the Great Seal Patent
Office on the 6th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
SIDNEY BROMHEAD, of Southsca, in the County of Hants, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Sixth day of October, 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 Samuel Sidney Bromhead, Her
special license that I, the said Samuel Sidney Bromhead, my executors,
administrators, and assigns, or such others as I, the said Samuel
Sidney Bromhead, 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, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for " A NEW OR IMPROVED RIVET SCREW OR FASTENING,'
upon the condition (amongst others) that I, the said Samuel Sidney
Bromhead, my executors or administrators, by an instrument in
"

page_text: writing under my, or their, or one of their hands and scals, 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 Samuel Sidney Bromhead, 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 thereof, that is to say :-
My Invention of an improved rivet screw or fastening consists of
manufacturing such rivets, screws, or fastenings of zinc wire after it has
been well annealed, so as to become perfectly malleable. The zinc wire
when annealed is converted into rivets, screws, or fastenings by any
ordinary machine or process, which are then ready for use without any
further preparation, thereby saving the cost of tinning or galvanizing;
and, as in the case of copper, being cheaper than the simple material,
while obtaining a better result.
Hitherto there has been much difficulty in joining some articles
together by means of rivets or screws capable of resisting corrosion
and oxidation. To try and meet this difficulty rivets and screws have
been manufactured of iron, and also of copper and afterwards galvanized
or tinned; but these are expensive methods, and only partially suc-
cessful, because in the course of time the coating becomes removed and
the rivets or screws corrode or oxidize.
I also manufacture of annealed zinc for similar purposes split rivets,
hollow rivets, or eyelets, screws, washers, bolts, and nuts.
In order to give extra, strength to these improved rivets, and to
prevent the heads from being forced off I manufacture them with
rounded necks, so as to join the head to the shank by a curve instead of
having a sharp corner. This shape gives greatly increased strength.
Now having particularly described and ascertained the nature of my
Invention, and how the same is to be carried into effect, I would have it
understood that I do not claim any particular shape for my improved
rivets, screws, or fastenings; but what I do claim and desire to secure
by the herein-before in part recited Letters Patent is the manufacture

page_text: of rivets, screws, or fastenings of annealed zinc wire as herein-before
described.
In witness whereof, I, the said Samuel Sidney Bromhead, have
hereunto set my hand and seal, this Sixth day of April,
in the year of our Lord One thousand eight hundred and seventy- {
four.
SAMUEL SIDNEY BROMHEAD. (L.S.)
