CERTAIN IMPROVEMENTS IN MAKING OR CONSTRUCTING HINGES OF VARIOUS DESCRIP- TIONS
Year: 1826

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
Cook, of Birmingham, in the County of Warwick, Brass Founder, send
greeting.
WHEREAS His most Excellent Majesty King George the Fourth, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Nineteenth day of January, in the sixth year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
Benjamin Cook, His special licence that I, the said Benjamin Cook, my
executors, administrators, and assigns, or such others as I, the said Benjamin
Cook, my executors, administrators, or assigns, should at any time agree with,
and no others, from time to time and at all times during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of
"CERTAIN IMPROVEMENTS IN MAKING OR CONSTRUCTING HINGES OF VARIOUS DESCRIP-
TIONS;" in which said Letters Patent there is contained a proviso obliging me,
the said Benjamin Cook, by an instrument in writing under my hand and
seal, particularly to describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, and to cause the same
to be iurolled in His Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Benjamin Cook, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, is described and ascertained
in the following explanation thereof (that is to say) :-
My improvements are as follows, which may be applied in the making or
constructing hinges made of cast or wrought iron, copper, brass, metal, or
mixtures of metals, or of parts of the above combined together, to form hinges;
that is, parts of the hinge may be made of cast or wrought iron and other
parts of metals, as I find convenient. But as my improvements will be better
understood by reference to the Drawings of one particular mode in the margin
of this my Specification, the other various ways in which I mean to apply the
principle may be easily conceived. No. 1 is a part of the hinge with a solid
or hollow pillar soldered in or otherwise made fast to the bottom part of the
joint with an iron or steel projection or pin A through it, intended to work in
the spiral groove in No. 2. No. 2, which slides on the solid or hollow pillar.
The iron or steel pin which passes through No. 1 is fitted to work in the worm
or spiral groove B, which, as the hinge opens, produces the rising motion in it,
and which raises the door to which it is fixed; No. 3, the tube that slides on
No. 2 to secure the worm, and makes the joint stronger; No. 4, the rising half
of the hinge, which slides on No. 2 and 3, and are all connected together by
-means of screws or pins, which cannot be shewn in a Drawing; No. 5, the
binge compleat and thrown open to its full rise. The object I have in view is
to produce a rising hinge, in which the opening in the joint and the disagreeable
appearance of the wire in it are removed by placing within tubes the mechanism
which effects this rising action of the hinge, so that the whole appearance of
the hinge is the same, except that when the hinge is open the middle tube, No. 5,
is rather smaller than the two ends. I have only described in my Drawings
one of the modes I use, which will serve to convey the idea how all ways may
be effected; but I claim the exclusive privilege of using this spiral groove and
every other method requisite, either by a screw, or worm, or spiral groove
concealed in tubes, in every way I may find convenient to make and construct
rising hinges.
In witness whereof, I, the said Benjamin Cook, have hereunto set my
hand and seal, the Fifteonth day of July, One thousand eight hundred
and twenty-siv
