Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
KING, of Webber Row, Westminster Road, in the County of Surrey, Engineer,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Fourth day of November, in the fifth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Henry
King, Her especial licence, full power, sole privilege and authority, that I, the
said Henry King, my exors, adñiors, and assigns, or such others as I, the
said Henry King, my exors, aditiors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my.
Invention of "CERTAIN IMPROVEMENTS IN STEAM ENGINES AND BOILERS;" in
which said Letters Patent is contained a proviso that I, the said Henry,
King, shall cause a particular description of the nature of my said Invention,
and the what manner the same is to be performed, to be inrolled in Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in and
by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Henry King, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascertained
in and by the following statement thereof, reference being thereunto had, will
more fully and at large appear.

page_text: The improvements relate, first, to improvements in cylinder engines. A
represents the cylinder with passages and surface slide. B shows the slide
connected to cylinder, with spring at the back, to resist the pressure of the
steam, and to keep the slide in its place, with a slide and box, top and bottom
of surface slide, with steam and exhaust pipes. C, the front of surface slide,
with top and bottom slide E, E, with lever for starting, reversing, or stopping
the engine. D, front or slide surface of engine with small ...
for
vibrating engines, and dotted lines for fixed cylinders...F.F,. is a thin plate
introduced between D and B for fixed cylinders, to be worked with a rod from
Figure 1 by a crank. or any other mode. G is a hollow groove turned for the
purpose of working upon friction rollers or any other bearing.
The second part of my Invention relates to improvements in rotary engines.
A, the outward appearance of the engine, with fly wheel and shaft keyed first
into the piston C, and showing stuffing box and gland. B, inside of cylinder,
with recess (Figure 3) for valve E to shut into, to allow the piston C to pass.
C, the piston, with small places left, as at Figures 1 and 2, for the valve E to
fall into, that the steam might have power to force the piston forward after
every revolution. E is a valve with metallic packing pressing on the piston C,
preventing the steam from passing back. D, the metallic packing for the
purpose of keeping the piston steam-tight in the cylinder B. F, the steam
pipe. G, the exhaust pipe. H, brass packing, with spring at the back for
preventing the steam from passing the joint of the valve E.
The third part of my Invention relates to improvements in boilers. Figure 1
represents the side view and section of boiler with fire tubes arranged inside.
It is furnished with a fireplace A, which is a coiled tube, Figure 1, which
reaches to the end of the fire-place, surrounding the whole of the fire.
Through this tube the water for the feeding of the boiler has to pass from
thence into the generating pipes, Figures 2, 3, 4, 5, 6, 7, 8, and 9, which is
laid from end to end of the fire-place, passing from thence to the pipe (Figure
10), and out of the valve B, which is for the purpose of preventing the water
from flying out too rapid; and also, in case of the fire tubes burning out or
bursting, the valve immediately closes, and shuts off all communication with the
boiler. The valve is furnished with a cover D, for the purpose of throwing the:
water downwards.
In witness whereof, I, the said Henry King, have hereunto set my hand
and seal, this Fourth day of May, in the year of our Lord One
thousand eight hundred and forty-two.
HENRY (L.B.) KING.
