Year: 1854

page_text: LETTERS PATENT to Thomas Frederick. Tyerman, of Weymouth Street,
Portland Place, in the County of Middlesex, Architect and Surveyor, for
the Invention of. "IMPROVEMENTS IN PREPARING HOOP IRON AND SUCH LIKE
METAL SURFACES USED FOR BONDINGS IN BUILDINGS AND STRUCTURES."
Sealed the 12th January 1855, and dated the 31st October 1854.
PROVISIONAL SPECIFICATION left by the said Thomas Frederick Tyerman
at the Office of the Commissioners of Patents, with his Petition, on the
31st October 1854.
I, THOMAS FREDERICK TYERMAN, of Weymouth Street, Portland Place, in
the County of Middlesex, Architect and Surveyor, do hereby declare the.
nature of the Invention for "IMPROVEMENTS IN PREPARING HOOP IRON AND SUCH.
LIKE METAL SURFACES USED FOR BONDINGS IN BUILDINGS AND STRUCTURES" to be.
as follows:-
This Invention has for its object so to prepare hoop iron and such like
metal surfaces to improve their bonding or holding capabilities, and consists of
subjecting them to mechanical processes to render the same rough or jagged.
or undulating at the surfaces and edges, in place of using such materials plain,
(as heretofore. For this purpose it is preferred that the edges should be cut or

page_text: notched at intervals, and the parts turned in succession in opposite directions;
but other forms of notches may be resorted to in carrying out the Invention,
and it is not essential that the edges should. be notched, as the requisite
roughing or undulating of the surfaces may be otherwise produced.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Frederick Tyerman in the Great Seal Patent Office
on the 30th April 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
FREDERICK TYERMAN, of Weymouth Street, Portland Place, in the County of
Middlesex, Architect and Surveyor, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Ter Letters
Patent, bearing date the Thirty-first day of October, in the year of our Lord
One thousand eight hundred and fifty-four, in the eighteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Thomas Frederick Tyerman, Her special licence that I, the said Thomas
Frederick Tyerman, my executors, administrators, and assigns, or such others
as I, the said Thomas Frederick Tyerman, 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
"IMPROVEMENTS IN PREPARING HOOP IRON AND SUCH LIKE METAL SURFACES USED
POR BONDINGS IN BUILDINGS AND STRUCTURES," upon the condition (amongst others)
that I, the said Thomas Frederick Tyerman, by an instrument in writing under
my hand and seal, 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 Thomas Frederick Tyerman, 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 consists of improvements in preparing hoop iron and such
like metal surfaces used for bonding in buildings and structures. The mode

page_text: by which this object is effected is by subjecting hoop iron or strips of other
metal to certain mechanical processes, which will produce on the edges or
surfaces, or on either or both of them, a rough or jagged, or notched, or
perforated, or undulating, or rasp-like, or spikey effect, or other such like
method or methods, whereby an additional key, tic, or hold may be made
upon or with the matters or substances brought in connection therewith, or
which may become imbedded thereon. There are several modes of effecting
this object, but that which I prefer is to use the ordinary hoop iron, but to
have the edges cut or notched to the extent of one-sixth part or thereabouts
of the width of the hoop iron, at intervals of about twelve inches (or more or
less) on alternate sides; but I prefer that the cuts or notches shall not be
opposite each other, and that one or both of the parts of these cuts shall
be turned in succession at an angle of about forty-five degrees, or thereabouts,
with the surfaces, and thus form notched or roughened or turned or serrated
edges, and that the notched, roughened, turned, or serrated edges shall be
alternated at each edge; that is, I mean that the first notched or turned piece
on the right-hand side shall be turned in the opposite direction to the first
notched or turned piece on the left-hand side, and so be continued for its
length alternated; or the hoop iron may be notched, as above described, on the
edges, but only turned on one side or surface; or the hoop iron, treated as
described, may have perforations through its substance, and the parts cut
through turned up on one or both sides, so as to produce an additional hold,
tic, or key to and with the materials or substances to be used in connexion

page_text: .
depths of or distances between the cuts or notches, or roughened or serrated
edges, nor to the angle at which the pieces may be turned up or turned down
or perforated, as above described, and shewn by the accompanying Drawing,
as they may be varied in many ways, so long as the peculiar character of my
Invention be retained; which is essentially a method or methods of producing
on the edges and surfaces, or upon one or both of them, of hoop iron or strips
of other metal, a roughness, whereby an additional tie, key, or hold may be
made from the matters or substances employed in connection therewith, or
may be more effectually imbedded thereon or indented thereinto. I claim
as my Invention the preparing and treating hoop iron, and such like strips of
metal used for bondings in buildings and structures, in such modes as to
produce notched, or jagged, or roughened, or serrated edges, and roughened or
rasp-like, or spikey, or perforated, or undulating surfaces, and thus. to obtain
more effectual tie or hold than when using such hoop iron or strips of metal
in the ordinary plain form, or treated as heretofore.
In witness whereof, I, the said Thomas Frederick Tyerman, have here-
unto set my hand and seal, this Twenty-seventh day of April, in the
year of our Lord One thousand eight hundred and fifty-five.
Witness,
JNO. ALCOCK.
