TO ALL TO WHOM THESE PRESENTS SHALL COME, we,

page_text: Foreman to Messrs. Brown, Lenox, & Co., of Billiter Square aforesaid,
send greeting.
WHEREAS the said George William Lenox and William Roberts
have, on this Eighteenth day of October, One thousand eight hundred-
and fifty-two, left at the office of the Commissioners of Patents for
Inventions a petition and declaration, praying Her Most Excellent
Majesty Queen Victoria, by Her Royal Letters Patent, to give and
grant unto us, the said George William Lenox and William Roberts,
Her especial licence, full power, sole privilege and authority, that we,
the said George William Lenox and William Roberts, our executors,
administrators, and assigns, or such others as we, the said George
William Lenox and William Roberts, our executors, administrators.
or assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term of fourteen years from
the date of such Letters Patent, may lawfully make, usc, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, and all Her said Majesty's Colonies
and Plantations abroad, our Invention of "IMPROVEMENTS IN MACHINERY
FOR RAISING AND LOWERING CABLES AND OTHER CHAINS."
And whereas we, the said George William Lenox and William
Roberts, do, according to the Statute in such case made and provided,
by this instrument or Complete Specification in writing under our
hands and seals, and the Drawing hereunto annexed, particularly
describe and ascertain the nature of the said Invention, and in what
manner the saine is to be performed, that is to say:
The Invention relates to improvements in apparatus to raise chain
cables, with their swivels and shackels, and other chains and weights
And in order that our Invention may be fully understood and carried
into effect, we will proceed to describe the same; reference being had to
the Drawing hereunto annexed, and to the figures and letters marked
thereon, that is to say:
Figure 1, shows an elevation of a capstan with the apparatus
applied. Figure 2, a vertical section of the apparatus. Figure 3, a
plan of the under side of the upper flanch plate or disc A. Figure 4,
a plan of the upper side of the lower flanch plate or disc B. The

page_text: upper and. lower plates or discs are made of wrought or cast iron
or other metal; the upper surface or plane of the lower plate is
parallel with the under side of the upper plate, and the two plates are
to be united at right angles to a barrel or centre piece, also formed of
wrought or cast iron or other proper material. by dovetailing or other
fastening. The barrel or centre piece, Figure 6, shews the openings
fff, to receive the stops D, D, on the lower plate or disc B, and dove-
tailed on the top or upper end to receive the upper plate or disc A, the
shape being made to suit the purpose for which it is intended. The
lower plate or disc is furnished with stops or teeth D, D, D, forined
out of the solid. or fixed on by rivets or other means, they being of a
shape exhibiting larger dimensions at inner end, and graduating smaller
to the extreme or outer end, both in height and width. and of a large
size, equal to the strength required. The number of teeth is not
material. ten being preferred. The upper plate or disc is furnished
with stops or teeth of much smaller dimensions than those on the
bottom or lower plate, they running rather deeper towards the middle,
though nearly uniform in size from in to out; see Figure 8, C, C, C.
The centre piece or barrel may be made in one with the lower plate or
disc, or may be united to it in such manner as may be deemed best.
By this arrangement the chain cables, with their swivels and shackles
or other chains, are received readily between the rim or flanched plates,
held firmly and delivered or discharged freely. The upper and lower
plates or discs can be used and united to the capstan or windlass body,
or spindle, with or without the centre piece or barrel. If the flanched
plates are intended to be used vertically the stops or teeth may be
uniform on the two plates, as shown at Figure 5.
It will readily be seen that from the configuration of the stops or
teeth, and being on parallel plates, chains of many sizes may be made
to work in the same rim or flanched plates effectively and freely.
Having thus described the nature of the Invention, we wish it to be
understood that we do not confine ourselves to the detail or precise
arrangement as herein shown, as the same may be varied without
departing from the principle of our improvements; but what we claim
is, the combination of apparatus herein described, consisting of the

page_text: plates A, B, and the peculiar forms of stops or teeth C, D, whether the
same be made of cast or wrought iron or other metal.
In witness whereof, we, the said George William Lenox and
William Roberts, have hereunto set our hands and seals, this
Twelfth day of October, One thousand eight hundred and
fifty-two.
