A STEAM OR FIRE ENGINE COMPRISING THREE OR ANY GREATER PLURALITY OF CYLINDERS, WITH THE APPENDAGES THERETO
Year: 1788

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
TOURNESS and JAMES ASHWORTH, of Elland, in the Parish of Halifax and
County of York, Gentlemen, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent, bearing date the Sixth day of November, in the twenty-
ninth year of His reign, give and grant unto us, the said Robert Fourness
and James Ashworth, His especial licence, that we, the said Robert Fourness
and James Ashworth, during the term of years therein expressed, should and
lawfully might use, exercise, and vend, within England, Wales, and the
Town of Berwick-upon-Tweed, our Invention of "A STEAM OR FIRE ENGINE
COMPRISING THREE OR ANY GREATER PLURALITY OF CYLINDERS, WITH THE APPENDAGES
THERETO;" in which said Letters Patent there is contained a proviso obliging us,
the said Robert Fouruess and James Ashworth, under our hands & seals, to
cause a particular description of the nature of our said Invention, and how
the same is to be perform'd, to be inrol'd in His Majesty's High Court of
Chancery within one calendar month after the date of the said recited Letters
Patent, as in and by the same, relation being thereunto had, may more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Robert Fourness and James Ashworth, do hereby declare that our said Inven-
tion of a Steam or Fire Engine, comprising Three or any greater Plurality of
Steam Cylinders, with the Appendages thereto, is described in manner
following

page_text: The said Robert Fourness and James Ashworth obtained, on the Fourth of
March last, His Majesty's Letters Patent for a new constructed machine, in the
Specification of which they represent a constructure similar to the engine
this present Specification describes. But it must be observed they now
introduce their engine under circumstances of alteration in principle which
renders it capable of being commodiously applied to the purpose of conveying
or impelling travelling carriages of every denomination, or giving circular or
other motions without the assistance of a fly, and without being burthened with
cold water for condensing the steam to produce a vacuum in the steam
cylinders, or having the machine complicated by the apparatus necessary to the
management and regulation of the said condensing water; and likewise by the
present construction of their engine they are enabled to apply the power of the
steam with their steam cylinders inverted, as the draft hereunto annexed
exhibits, or in any other position, by virtue of using three or a greater plurality
of steam cylinders, but three form the more simple and expedient construction.
DESCRIPTION.
A, A, the boiler and case, or flue in which the boiler stands; B, the steam
pipo; C, a stopcock by which the steam is kept off or turned on to the cylinders,
as occasion requires; D, a large cock, into the barrel of which is intro-
duced as many pipes as there are cylinders, whose pin, being hollow, receives
the steam at its top, and is circularly regulated by the wheel E, which wheel
has its movement by an upright spindle, having a wheel 'fix'd on the bottom and
another on the top, which has action given to it by the wheel II, upon the axis
of the excentric wheels G, G, two wheels of equal or unequal diameters, one
being fixed upon the axeltree of the hind wheels of the carriage, and the other
upon the spindle or axis of the excentric wheels. In some cases we mean to
put several wheels of various diameters upon each axis. I, I, a sido plan of the
cylinders; J, J, J, three studds as they are fixed in the excentric wheels, to each
of which studds is connected a rod and bases as K, K, which, rod, being fixed
to the perpendicular rod of each piston, forces round by the power of the
steam the excentric wheels J, J, J, which communicate the motion, as already
described, to the appendages of the engine. F, another rotative cock, into the
barrel of which is lead a pipe from each cylinder, through which pipe each
cylinder alternately evacuates its, steam, which cock F is regulated by a cog
'wheel fix'd upon its pin or key, which takes its movement from the wheel E,
by a wheel or pinion being fix'd between thein in order that this cock and the
cock I shall both revolve the same way. L, a lever or winch, by which the
carriage is to be guided by the tooth and pinion M, M. We can effect tho

page_text: same guidance by chains and other implements in place of the tooth and
pinion.
N.B. The steam which passes through the cock F, after effecting its
use in the cylinders, is conducted by a pipe into a cistern of water, which
water it keeps hot for the supply of the boiler, which supply of hot water is
raised into the boiler by a force pump, the piston rod of which is connected to
one of the perpendicular piston rods of the steam cylinders; the same supply
to the boiler we can effect in different ways. One of the hind wheels of the
carriage must be fast upon the axletree; and be it understood that the hind part
of the carriage on which the engine is fix'd, as here described, may be separated
from the fore part at letter N, and connected and the power of it applied to
any other carriage of whatsoever description by bolts, chains, swivels, or other
apparatus. A safety valve is necessary to the boiler. A crank in various
forms may be applied in lieu of the excentric wheels,
In witness whereof, we, the said Robert Fourness and James Ashworth,
have hereunto set our hands and seals, this Sixth day of December, in
the year of our Lord One thousand seven hundred and eighty-eight.
