IMPROVEMENTS IN THE MANUFACTURE OF FLAT PIT CHAINS
Year: 1844

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
PERSHOUSE PARKES, of Dudley, in the County of Worcester, Manufacturer
of Chain Cables, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fourteenth day of March, in the seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Henry Pershouse Parkes, Her especial licence, full power, sole
privilege, and authority, that I, the said Henry Pershouse Parkes, my exors,
admors, and assigns, or such others as I, the said Henry Pershouse Parkes,
my exors, adñiors, 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 FLAT PIT CHAINS;" in which said Letters Patent is contained
a proviso, that I, the said Henry Pershouse Parkes, 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 appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry Pershouse Parkes, do hereby declare that the nature of my said
Invention, and 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 Drawing hereunto annexed, and to the figures and letters
marked thereon, that is to say:-
My Invention has for its objects certain constructions of flat pit chains here-
after described; and in order that the Invention may be most fully under-
stood and readily carried into effect, I will proceed to explain the Drawing
hereunto annxed.

page_text: for making one of the narrower links, the wide links differing only in the
width, being twice that of the narrow ones, so that like strength will be
obtained, whether a link be formed of one part h, h, or of two parts i. i.
Figure 9 shows a plan and edge view of a welded link i; and Figure 10
shows a plan and edge view of a welded link h; all which will readily be
understood by examining the Drawing; and it will be seen that the iron
is so rolled or forged as to produce extra thickness at the parts where the wear
will take place. This chain is combined by axes or pins in the same manner
as that described in respect to Figure 1. The circumstance of making the
knuckle joints by using the links i, i, of two parts, and the links h of one part,
and avoiding the filling up of the parts f, g, with metal, tends materially to
lighten the chain, and the same is more readily made in other respects; the
construction and arrangement of the links of the chain, Figure 7, will be prac-
tically the same as that described in respect to Figure 1.
I would remark, that although I have shown the flat surfaces of the metal to
be on the inside of the links, that may be reversed.
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
what I claim is the mode herein described of manufacturing flat pit chains
with welded links.
In witness whereof, I, the said Henry Pershouse Parkes, have hereunto
set my hand and seal, this Eleventh day of September, in the year
of our Lord One thousand eight hundred and forty-four.
HENRY PERSHOUSE (L.S.) PARKES.
AND BE IT REMEMBERED, that on the Eleventh day of September, in
the year of our Lord 1844, the aforesaid Henry Pershouse Parkes came before
our said Lady the Queen in Her Chancery, and acknowledged the Speci-
fication aforesaid, and all and every thing therein contained and specified,
in form above written. And also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
Enrolled the Fourteenth day of September, in the year of our Lord One
thousand eight hundred and forty-four.
