AN IMPROVEMENT IN T-FASTENINGS
Year: 1863

page_text: LETTERS PATENT to Herbert William Hart, of Fleet Street, in the
City of London, Manufacturer, for the Invention of "AN IMPROVEMENT IN
T-FASTENINGS."
Sealed the 15th March 1864, and dated the 18th September 1863.
PROVISIONAL SPECIFICATION left by the said Herbert William Hart
at the Office of the Commissioners of Patents, with his Petition, on
the 18th September 1863.
I, HERBERT WILLIAM HART, of Fleet Street, in the City of London,
Manufacturer, do hereby declare the nature of the said Invention for "AN
IMPROVEMENT IN T-FASTENINGS," to be as follows:-
My Invention refers to those T-fastenings in which the leg or shank is
composed of two separate pieces, which after being inserted through the
article to which the fastening is to be applied are turned down, and embrace
the article between the head of the T and the turned down shank.
fastenings as hitherto made are found to be weak and readily open their whole
length, and break or assume the form of a single strip of metal.
Such
Now my present Invention consists in stamping or otherwise forming the
metal of which the fastenings are formed with lugs or flanges, which after the
fastening has been bent into the T form are turned down upon (by preference),
the inner face of the head and thereby give strength and solidity to the
fastening.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HERBERT
WILLIAM HART, of Fleet Street, in the City of London, Manufacturer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of September, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Herbert William Hart, Her special licence that I, the said Herbert
William Hart, my executors, administrators, and assigns, or such others as
I, the said Herbert William Hart, 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
"AN IMPROVEMENT IN T-FASTENINGS," upon the condition (amongst others)
that I, the said Herbert William Hart, 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 Herbert William Hart, 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 thereof, reference being had to the Drawings ⚫hereunto
annexed, that is to say:-
My Invention refers to those T-fastenings in which the-leg or shank is com-
posed of two separate pieces, which after being inserted through the article
to which the fastening is to be applied, are turned down and embrace the
article between the head of the T and the turned down shank. Such fastenings
as hitherto made are found to be weak and readily open their whole length
and break or assume the form of a single strip of metal.
Now my present Invention consists in stamping or otherwise forming
the metal of which the fastenings are formed with lugs or flanges, as

page_text: represented in Figure 1 of the accompanying Drawings, which after the
fastening has been bent into the T form are turned down upon (by pre-
ference) the inner face of the head and thereby give strength and solidity to
the fastening.
Figure 2 shows the metal partly bent into the T form; Figure 3 the
T form complete before the turning down of the lugs or flanges; and Figure 4
the fastening with the lugs or flanges turned down upon the inner face of the
head.
And having now described the nature of my said Invention, and in what
manner the same is to be performed I declare that I claim, constructing
T-fastenings with lugs or flanges in manner and for the purpose herein-before
described.
In witness whereof, I, the said Herbert William Hart, have hereunto
set my hand and seal, this Eighteenth day of
One thousand eight hundred and sixty-four.
HERBERT WILLIAM HARTL.S.)
