Street, in the Parish of Saint James, Westminster, in the County of Middlesex,
Whitesmith, send greeting..
.. WHEREAS. His most Excellent Majesty King George the Third, by Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster, the
Fifteenth day of January, in the twenty-eighth year of His reign, hath given
and granted unto him, the said James Angell, his executors, adñiors, and
assigns,-His special licence, full power, sole privilege and authority, that he,
the said James Angell, his executors, adiñiors, and assigns, and every of them,
.himself and themselves, or by his deputy or deputies, servants or agents, or
such others as he, the said James Angell, his executors, admors, or assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term of years therein expressed, should and
lawfully might make, use, exercise, and vend, within that part of the Kingdom
of Great Britain called England, the Dominion of Wales, and Town of
Berwick-upon-Tweed, and all His Majesty's Plantations and Colonies abroad,
his Invention of "CONSTRUCTING, HANGING, AND FIXING BELLS, NIGHT BOLTS,
AND DOOR. LATCHES IN DWELLING HOUSES AND OTHER PLACES WITH WHEELS AND
CHAINS, IN LIEU AND INSTEAD OF CRANKS, THAT WILL BE MORE BENEFICIAL TO
THE PUBLICK, AND FREE FROM THE DEFECTS THAT ATTEND THE HANGING OF
BELLS, NIGHT BOLTS, AND DOOR LATCHES BY THE CRANK NOW IN USE;" in which
said Letters Patent is contained a provisoe, that if the said James Angell
shall not particularly describe and ascertain the nature of the said Invention,
and in what manner the same is to be performed, by an instrument in writing
under his hand and seal, and cause the same to be inrolled in His Majesty's

page_text: High Court of Chancery within one calendar month next and immediately
after the date of the said Letters Patent, that then the said Letters Patent,
and all liberties and advantages whatsoever thereby granted, should utterly
cease, determine, and become void, as in and by the said in part recited Let-
ters Patent, relation being thereunto had, may more fully and at large appear.
NOW KNOW YE, that in compliance with, and agreable to the true
intent and meaning of the said provisoe in the said Letters Patent contained,
I, the said James Angell, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, is and
are described and ascertained in manner following, that is to say: By
a wheel, made of any hard metal, ivory, or any other hard and durable
substance whatsoever, with a grove or chanel upon the edge of the wheel,
the wheel to be fixed upon an axis or spindle through the centre of it, and
made secure in its situation, in manner herein-after mentioned. The wheel may
be placed either in a vertical, horizontal, or any other direction that occasion
may require; the axis must be rivetted or burred at the outer end' to secure the
wheel from coming off, and there must be a shoulder on the axis, to keep the wheel
in its situation and prevent it from running back. In the groove or channel
of the wheel a flat, round, or oval chain must be laid, and made fast with a pin,
which must be rivetted, so as to prevent the chain from coming out of the
groove or channel. The Figure No. 1, hereunder drawn, represents the
wheel in a front view, with a hole in the centre, through which the axis or
spindle must pass for the wheel to turn upon. The Figure No. 2 represents
the wheel in a vertical side view, with the groove or channel in which the
chain is to be laid; the diameter of the wheel must be at discretion, according
to weight of the bell required to be hung. The Figure No. 3 represents the
chain, made of flat links rivetted together, and similar in all respects to the
chain round the barrel of a watch. The Figure No. 4 represents the oval
chain, and the Figure No. 5 represents the round chain; the flat chain is least
liable to accident. The Figure No. 6 represents the spindle or axis for the
wheel to turn upon, the end of which, at letter A, must be made round, and
fitted to the size of the hole in the wheel, and at the bottom of the round part
of the spindle there must be a shoulder to keep the wheel in its situation;
from the shoulder it must be made tapering to a point, in order to drive or
screw when the wheel is put on the round part of the axis; the axis must be
rivetted or burred to prevent the wheel coming off. The Figure No. 7
represents a side shank, with an axis for the wheel to turn upon. The Figure
No. 8 represents a side view of a frame for the wheel to turn in, and is
similar to that of a pully frame with a screw. The Figure No. 9 represents

page_text: a front view of the same frame. The Figure No. 10 represents a front view
of the wheel and chain as fixed in a frame; the letter C on that Figure
represents the end of the pin as rivetted through the edge of the wheel and
chain, to prevent the chain from coming out of the groove, and serves as a stop
to the pull. The Figure No. 11 represents a vertical side view of the wheel
and chain as fixed in the frame. The Figure No. 12 represents a vertical side
view of a wheel and chain, with the axis or spindle in an horizontal direction
with letter D, which shews the pin as fixed near the edge of the wheel to
prevent the chain from coming out of the groove. The Figure No. 13
represents the side view of the wheel and chain placed in an horizontal
situation. The Figure No. 14 represents the wheel, chain, and side shank in
an horizontal side view; the letter (E) shews the pin or stubb rivetted into the
shank near the inner edge of the wheel to prevent the chain from coming out
of the groove.
The Figure No. 15 represents the wheel, chain, and side
shank in a front view; the letter F shews the pin or stubb rivetted in the end
of the shank near the outer edge of the wheel. The Figure No. 16 represents
a front view of the wheel, chain, and axis when fixed; the letter G in the same
The
Figure shews the rivett through the edge of the wheel and chain.
Figure No. 17 also represents a front view of the wheel, chain, and axis, with
a pin or start drove near the edge of the wheel, to prevent the chain from
coming out of the groove. The sundry wheels are fixed on the different axis,
spindles, shanks, or in frames may be fixed, as the different situations require,
to lead from the pull to the bell, and wherever fixed wire must be introduced
and made fast to the chain or chains; the rivetts through the wheel and chain,
or pins, stubbs or starts, are used as situations require, and either the flat,
round, or oval chain may be used at discretion.
In witness whereof, I, the said James Angell, have hereunto set my hand
and seal, the Thirty first day of January, One thousand seven hundred
