Year: 1789

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, WILLIAM
SHORLAND, of the City of Bristol, Esquire, sends greeting.
WHEREAS His most Excellent Majesty, by Letters Patent under the Great
Seal of Great Britain, bearing dated the Thirtieth day of July, in the twenty-
ninth year of His reign, gave and granted unto me, the said William Shor-
land, my executors, administrators, and assigns, his special licence, full power,
sole priviledge and authority, that I, the said William Shorland, my executors,
administrators, and assigns, by myself or themselves, or by mine or their
deputy or deputies, servants or agents, or such others as I, the said
William Shorland, my 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 years therein expressed, should and lawfully might make,
use, exercise, and vend my Invention of "A REGULAR ROTATORY MOTION TO GO
BY A STEAM ENGINE WITHOUT ANY CRANK OR COG WHEEL, THE MACHINERY OF WHICH
IS TO BE FIXED UPON NEW INVENTED GUDGEONS AND BRASSES;" in which said
Letters Patent there is a proviso that if I, the said William Shorland,
should not, within one calendar mouth from the date of the said Letters
Patent, cause a particular description of the nature of my said Invention, and
in what manner the same is to be performed, by writing under my hand and
seal, to be inrolled in His Majestie's High Court of Chancery, that then the
said Letters Patent, and all liberties and advantages whatsoever thereby
granted, should utterly cease, determine, and become void.

page_text: NOW KNOW YE, that I, the said William Shorland, in compliance with
the said proviso, do by this instrument declare that the nature of my said
Invention, and the manner in which the same is to be performed, is described
in the words following, viz*:-
My method of making or constructing the machinery for a regular or
rotatory motion to go or work by a steam engine or engines commonly called
fire engines, consists of the following principles:-First, a shaft, of any
length or size required, commonly known by or called a water-wheel shaft or
a main shaft, fixed upon new invented gudgeons and brasses to ease or lessen
friction. My method of making them is to have one part of the round or
bearing of common gudgeons to be made in the same form or method of a
tooth or cog wheel. This part is to run or work upon a second cog wheel of
any heighth or size required. The other part of the round or bearing of the
gudgeon is supported on each side, forming two perpendicular lines made with
brass, iron, or any other hard metals.
My method of placing or fixing the machinery together proper for working
or performing its regular motion by the help of the steam or fire engines:-
The shaft being fixed as above mentioned, I then add to the main shaft a
catch wheel or wheels, with proper catches, fixed to the first and second
levers, of any length or size the strength of the work or the nature of the
machinery may require. Also three levers fixed in the manner following:-
The first lever, one end of which is fastened to the main shaft; at the other
end is fixed a chain leading to and fixed to the arch head of the cylinder- beam.
The second lever is fixed in like manner to the first, one end to the main
shaft; at the other end is fixed a chain leading to and fastened to a convenient
part of the third lever. And at one end of the third lever a chain is fixed
leading to and fastened to the arch head of the cylinder beam likewise; the
other end of this lever works on a center. The gudgeons and brasses above
mentioned, with a tooth chain to work into teeth wheels, for rising coal and all
kinds of ores or the produce of mines of any depth, is to work with or be
drove by the above-mentioned machinery, and be used, applied, extended to
all and every work or works, carriage, or machinery of any kind or nature that
hath any motion. By method of making the above-mentioned chains is
to have plates or links with teeth in one edge, and put together in the common
way or method with pins and keys, or rivetted in the usual manner of steam or
fire engine chains is made. The chain, when at work, the upper part will
form a half circle, and the bottom the same. The two sides of the chain will
form two perpendicular lines. It will be an endless tooth chain. The two
ends is also fastened together with pins or rivets, and is to work in as many

page_text: teeth wheels as the length of the chain will require, to prevent its breaking or
destroying itself by its own weight, or any thing that it may be loaded with,
as above mentioned.
In witness whereof, I, the said William Shorland, have hereunto set
my hand and seal, this Twenty-ninth day of August, One thousand
seven hundred and eighty-nine.
WILLIAM (L.S.) SHORLAND.
