page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, J, WILLIAM
ARMITAGE, of Charles Street, in the Parish of Saint Marylebone, in the
County of Middlesex, Furnishing Ironmonger, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Seventh day of September, in the thirty-second year of His
reign, give and grant unto me, the said William Armitage, His especial licence
that I, the said William Armitage, during the term of years therein mentioned,
should and lawfully might use, excercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "KITCHEN RANGES,
STOVES, AND GRATES UPON AN IMPROVED CONSTRUCTION, CALCULATED TO PRODUCE A
GREATER HEAT WITHOUT ANY EXTRAORDINARY CONSUMPTION OF FUEL THAN ANY NOW
IN USE, AND WHEREBY THE FIRE MAY BE MORE SAFELY AND EXPEDITIOUSLY EXTIN-
GUISHED THAN HATH HITHERTO BEEN EFFECTED;" in which said Letters Patent
there is contained a proviso, obliging me, the said William Armitage, by an
instrument in writing under my hand and seal, to cause a particular description
of the nature of my said Invention, and in what manner the same is to be per-
formed, to be inrolled 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, I, the said
William Armitage, do hereby declare that my said Invention is described iu
the plan hereunto annexed, and in manner following, that is to say:-

page_text: The ranges, stoves, and grates are made to give a greater heat into the
room by the front of range, stove, or grate, which is composed of sundry bars,
being fixed at one inch and a half, two inches, less or more, distance from each
other, horizontally, or in any direction whatever, and may be fixed into standard
bars, side plates, or checks, which front bars form a concave, hollow, or bow
inwards towards the back of the range, stove, or grate, 2, 3, 4, 5, or 6 inches,
less or more, from the straight line, which bow may be either circular, elliptic,
segment of any circle, or of any angle whatever, and may be applied to backs of
ranges, stoves, or grates either circular, elliptic, segment of any circle, or of any
angle whatever. The bars which form the front of the range, stove, or grate
may be either flat, round, square, or of any angle whatever, and may be fixed
into standard bars, or to checks or side plates, either flat or straight, circular,
elliptic, a segment of any circle, concave or convex, or of any angle whatever;
the form of back of range, stove, or grate, and also the front bars, which is pre-
ferred, is a segment of a circle. Figure 4 is a section of back, front, and bottom
of grate, with rollers for chains annexed. The front and bottom of the range,
stove, or grate, with the standard bars, checks, or side plates, may be made not
to move, or to move by drawing in and out, with or without handles or knobs
fixed at each side of the front of range, stove, or grate; the standard bars,
checks, or side plates may move without or upon wheels, casters, or rollers, to have
their bearing from the ground, as Fig. 5, or level with the bottom of the range,
stove, or grate, which may also move in a groove with friction rollers at each
side; or may work in and out by a spiral worn, and a rack fixed at or near the
centre of the front under the bottom of the range, stove, or grate; or may
work in and out by a male and female screw fixed at or near the centre of the
front under the bottom of the range, stove, or grate; or may work in and out
by two, three, or more wheels upon an axis or centre to work one, two, or more
racks fixed under the bottom of the range, stove, or grate, as Fig. 1; or may
wind in and out by a roller upon an axis or centre at each side of the range,
stove, or grate, to which are fastened chains, which are also fastened to the
bottom of range, stove, or grate, which run in two pullies or rollers fixed at
or near the centre under the bottom of the range, stove, or grate, as Fig. 2.
The bars which form the front of the range, stove, or grate may be fixed
or framed into standard bars, with or without wheels, casters, or rollers at
the bottom of the same, having bars on the straight, fixed or framed to the
standard bars at each side, of any length required, to run in and out with the
front bars, as Fig. 8. The top bar of range, stove, or grate may be made to
fall down level with the second bar, to retain the same side uppermost when
let down by the top bar, being hung on an axis or centre at each end or side

page_text: to two supports, with notches or stops to receive the top bar when let down,
reaching to the second bar, and acting on a centre at each end or side. Tho
checks to contract the fire may be made of the same shape with the back of
range, stove, or grate, to swing on a. hinge or pivot at or near the centro of
tho back, as Fig. 11, to be worked from the back to the front of range, stove,
or grate by wheels and racks, forming a segment of a circle, or by spiral
worms and racks forming a segment of a circle, as Fig. 12; or by cheeks
made straight or flat, and fixed to racks of the same segment of circle with
the back of range, stove, or grate, to be worked at each side by wheels, as
Fig. 9. Fig 10 is the cheek, rack, and wheel separate. The front of range,
stove, or grate being made to draw or wind in and out, not only serves to
contract the fire, but to let the fire readily out, by drawing or winding out tho
front of range, stove, or grate farther than level with the hobs, or sides of
range, stove, or grate. The fire may be also readily extinguished by the
bottom of range, stove, or grate being made at one end to swing on a joint
or swivel or pivot, supported by a bar or more, to move with or without wheels
casters, or rollers at the bottom of the same, to be drawn out by a handle at
the other end, as Fig. 6, or wound out by wheels and a circular rack. The
ranges, stoves, and grates may be made of cast or wrought iron, copper, brass,
or any metal or composition of metal, or any substance that will bear the heat
of fire. Fig. 7 is a range compleat; Fig. 3 is a stove or grate compleat.
In witness whereof, I, the said William Armitage, have hereunto set my
hand and seal, this Sixth day of October, in the year of our Lord One
WN ARMITAGE. (L.S.)
