IMPROVEMENTS IN THE MANUFACTURE OF HINGES
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
WILKES, of Wolverhampton, in the County of Stafford, Ironfounder, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-sixth day of April, in the eighth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
Samuel Wilkes, Her especial licence, full power, sole privilege and authority,
that I, the said Samuel Wilkes, my exors, adññors, and assigns, or such others
as I, the said Samuel Wilkes, my exors, adññors, 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 "IMPROVEMENTS IN THE MANUFACTURE OF HINGES;" in
which said Letters Patent is contained a proviso, that I, the said Samuel
Wilkes, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in and
by the same, reference being thereunto had, will more fully and at large
appears.
NOW KNOW YE, that, in compliance with the said proviso, I, the said
Samuel Wilkes, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had
to the Drawings hereunto annexed, and to the- figures and letters marked
thereon (that is to say) :-
In making binges with cast metal flaps and knuckle joints, as heretofore
practised, it has, for the most part, been usual first to cast one flap of a hinge
with its parts of the knuckle joints, and then at a second casting, to cast thereto
the other flap and its parts of the knuckle joints. Another mode of making cast
hinges which has been practised since One thousand eight hundred and forty
to some extent, is by casting the two parts of the knuckle joints and the two
flaps at the same time, as was described in the Specification of a Patent
granted to me on the 21st day of January 1840, for such mode of making
cast hinges. Now, the object of my present Invention is to form the knuckle
joints (for hinges) without flaps by casting or otherwise, separately, and then
having combined them on axes and placed them in. suitable moulds, to cause
the flaps to be cast thereto.
And, in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued. by me iii
making hinges.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a front view of a hinge constructed. according to my
Invention Figure 2 is a back view thereof; Figure 3 shews an end view;
Figure 4 is a transverse section of the binge; and Figure 5 shews the parts
'of the knuckle joints of a hinge in the position they would be placed in a
mould to have the flaps cast thereto. The knuckle joints are composed of the
separate parts a, a, a, and b, b; they consist of short hollow cylinders, having
each a slit or opening at c, and the parts a, b, are similar to each other, except
that the outer ends of the parts 6 have no holes for the axes, the other ends
of the cylinders b, having holes for the axis. The two ends of each of the
cylinders a have holes for the passage of the axis, hence the separate cylinders
a, a, a, and b, b, will, before having the flaps cast thereto, turn freely and
separately on the axis. The workman having placed the knuckle joints
a, a, a, and b, b, on an axis, these combined parts are to be put into a mould, as
is shewn at Figure 6; the workman taking care that the openings c of the
knuckle joints are correctly placed in the mould, as shewn. Figure 7 shews the
other half of the mould, and it will readily be understood,
parts of the mould are combined and the metal run in, that the saine will
enter the hollow cylinders a, a, a, and b, b, and produce a hinge, such as is
that when the two

shewn at Figure 8, so that the metal of the flaps does not come in contact.
with the axis when it flows through the slit or opening into the interior of the
knuckle joints. I would remark, that it is not necessary that the knuckle
joints should be of the same metal as the flaps; thus, for instance, I some-
times make the knuckle joints of brass and the flaps of cast iron, in which
case, if desired, the flaps may be covered with thin sheet brass rivetted
thereto.
Having thus described the nature of my Invention, and the best means I
am acquainted with for performing the same, I would have it understood that
I do not confine myself to the precise details so long as the peculiar character
Invention be retained; but what I claim is, the mode of manufacturing
hinges, herein described, whereby hollow knuckle joints without flaps are first
made and placed on axes, and then have the flaps cast thereto.

In witness whereof, I, the said Samuel Wilkes, have hereunto set my-
hand and seal, this Twenty-sixth day of July, in the year of our
Lord One thousand eight hundred and forty-five.
