IMPROVED STEAM ENGINE, FIRE ENGINE, AND JOINTS FOR CONNECTING PIPES OR LEATHER HOSE TOGETHER
Year: 1814

FIRE ENGINE, AND JOINTS FOR CONNECTING PIPES OR LEATHER HOSE TOGETHER."
Firstly, Figure 1 represents the engine A. One part of my improvement
in this engine, if worked by pistons, consists in the advantage of being able
at all times to get at all the valves without taking the engine to pieces. This is
done by drawing the bottom box B, which box is constructed with two hanging
or other valves, one receiving the water from the draught pipe C, as repre-
sented in the engine bed D, and the other valve opening in the delivery pipe E;
F is a section of the engine bed, barrels, valves, air vessel, and pistons.
Another part of my improvement consists in working the engine without
pistons, which is done by the means of one or more spiral worms or cylinders,
or part thereof. The spirals or cylinders are represented by Figures 2 and 3.
Figure 2 represents a section of the cylinder with the spiral worm fixed on
the hollow axis, with which the draught and delivery pipes are connected;
the water, being drawn up the draught pipe H, is forced through the delivery
pipe G, into the air vessel or hose by the power of the spiral. I represents
the valve in the draught pipe. K represents the valve in the delivery pipe.
These valves may be placed in any other situation, but are unnecessary where
the cylinder revolves, or where the spiral is continued in a reversed diagonal,
as represented by Figure 3. Either of the cylinders may be worked in

page_text: various positions and by various ways, such as by a capstan or windlass, or
by winches, levers, or multiplying wheels; and these cylinders are particularly
advantageous to all shipping and engines in general, where a great quantity
of water is required to be raised; and the cylinder may be worked as an
engine pump or machine, either by lifting or forcing the water with it.
Secondly, my improved joint or screw for connecting pipes or leather hose
together consists in a socket and nut, as represented by Figures 4 and 5. L,
in Fig 5, represents a nut with two pieces of metal at the end, which pieces,
being inclined planes, are put into the socket M, in Figure 4. The nut is to
go in at the part N, N, in Figure 4, and, on being turned round, tightens
against the two pieces of metal 0, 0, in the socket M, and which pieces of
metal 0, 0, are also inclined planes. The inclined planes, so adjoined or
affixed to the nut and socket respectively, may be increased from two to more
in number on cach, or may be continued as one square thread or worm.
Figure 6 is a section of a cast-iron pipe, which is connected or joined in the
same manner as the said socket and nut.
Thirdly, Figure 7 represents my improvement in the steam engine. This
consists in making a vacuum and condensing without the assistance of the
air pump, or by means of a very small one. P is the condensing vessel, which
is fixed from thirty to forty feet high from the level of a drain or river. Q,
the injection pipe, injecting a continual stream; R, the cistern or pool, to be
supplied by a pump or stream within thirty feet of the condensing vessel.
S, the steam pipe from the cylinder, the steam from the cylinder passing
through the pipe into the condensing vessel. The steam is condensed by the
cold jet of water in pipe Q, and as a column of water cannot rise higher
than thirty-two feet, it leaves a vacancy in the condensing vessel, and conse-
quently all water injected by the pipe Q runs out by its own gravity at the
bottom of the pipe W into the reservoir, and from thence conveyed down any
drain, &c. By these means the labour of the air pump is saved, and a more
complete vacuum is made. By the cock T you may at any time clear the
condensing vessel of any air that may collect, and which air will pass out of
the valve V.

fifty-fourth year of the reign of His Majesty King George the Third, the said
William Alfred Noble came before said Lord the King in His Chancery,
and acknowledged the Instrument aforesaid, and all and every thing therein
5 contained and specified, in form above written.. And also the Instrument
aforesaid was stamped according to the tenor of the Statute made in the
forty-eighth year of His said Majesty's reign.
