Year: 1815

page_text: CUTLER'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
CUTLER, of Great Queen Street, Lincolns Inn Fields, in the County of Mid-
dlesex, Iron Founder, send greeting.
WHEREAS His most Excellent Majesty King George the Third, did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Sixth day of January,
in the fifty-fifth year of our reign, give and grant unto me, the said John
Cutler, my exors, adiñiors, and assigns, His especial licence, full power, sole
priviledge and authority, that I, the said John Cutler, my exors, adñiors, and
assigns, should and lawfully might, during the term of years therein mentioned,
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick upon Tweed, my Invention of "CERTAIN IMPROVEMENTS APPLICABLE TO
FIRE-PLACES, STOVES, &c.;" in which said Letters Patent there is contained a
proviso that if I, the said John Cutler, shall not particularly describe and
ascertain the nature of my said Invention, and in what manner the same.
is to be performed, by an instrument in writing under my hand and seal, and
cause the same to be inrolled in our High Court of Chancery within six"
calendar months next and immediately after the date of the said Letters Patent,
that then the said Letters Patent, and all libeties, and advantages whatsoever
hereby granted, shall utterly cease, determine, and become void, as in-and by
the same, relation being thereunto had, may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Cutler, do hereby declare that the nature of my said Invention, and
manner in which the same is to be performed, are particularly described and
ascertained in manner following, that is to say:-
Firstly, with regard to the nature of the same, it doth consist in the offering
fuel for combustion in a more beneficial and economical manner, which is
effected by means of my said improvements applicable to fire-places, stoves,
&c.; and, secondly, with regard to the method of performing it, is clearly set
forth herein-after, and by the Drawings or Designs hereunto annexed, and
figured 1, 2, 3, 4, of and in which the same parts are universally distinguished
by the same numerical characters or letters of the alphabet; and Fig. 1 repre-
sents a front view of a stove similar in appearance to those well known by the
name of register stoves, with my said improvements herein-after described.
Fig. 2 represents a top view of the same; Fig. 3, a view of the nature of a
section; and Fig. 4, a back view of the same, and the parts marked with
A, B, C, D, and E, are parts similar to those in common use, and constitute no
part of my said improvements; and in reference to the separate parts, 1 repre-
sents the end of the axis of the pinion 2 passing through a circular hole in
the plate A, with a square hole in the said axis (which may be concealed by
fastening on by means of two small holes on each side an ornament like that
seen in the similar situation on the other side) for receiving a square pin or
keying piece affixed to a winch or other lever 18, and capable of being turned
thereby. 3 is a contrate wheel, taking in and receiving motion from the
pinion 2, and fixed on the axis 4, 4, to which are fastened the chains 5, 5, 5, 5,
capable of being wound thereon by the rotation thereof, and to the other end
of the said chains 5, 5, 5, 5, is affixed the bar 6, capable of passing freely
up and down in certain grooves in the side plates 8, 8, as seen in the
section, Fig. 3, where one of the said grooves are represented at 15, 15; and 7
is a plate of iron placed and fastened upon the bar 6, and of such dimensions,
as with its surface horizontal to pass freely up and down the chamber formed by
the plate 8, 8, and 12, 13, with and upon the said bar 6, and acts in the situation
of a moveable bottom to the said chamber. 9 is a pin leading through the
plate B, and joined to 14, 14, a pall taking in the pinion 2, and keeping the
same motionless whilst locked therein. 10 is a plate of iron formed of such
dimensions as to leave between the said plate and the back D the open
space 17, having communication with a flue or chimney, and of such capacity
as to cause across the top of and through the fire or part ignited, hereafter
mentioned, a draft or current of atr by experiment or otherwise found to be
necessary to support the combustion required. 11, 11, 11, 11, is a plate of iron

page_text: in a similar situation to the cover or flap of a register stove fastened or by its weight
remaining stationary on the bevel cheeks B, B, and leaving the small opening 16,
likewise having communication with the flue or chimney, and allowing a small
current of air to pass through the same, and I do lower my said moveable bottom 7
to the situation seen at 7, Fig 3 and 4, and do fill my said chamber formed by the
same and the plates 8, 8, 12, 18, with coal or other suitable fuel, and likewise my
stove or fire-place above the same, and do light the said coal or other suitable fuel
at the top thereof, the same being kept in ignition by the draft or current of air
passing through the space 17, and the draft or current of air passing through the
space 16 serving to carry off any dust, and thereby keep the parts above in better
preservation, and as the said fire or part ignited consumes the said coal or other
suitable fuel, I do press upon the pin 9, and lift the pall 14, 14, and by means
of the winch or other lever 18 taking in the axis of the pinion 2, turn the said
pinion, and thereby, by the before-described connection, cause the said bar 6
and the plate thereon 7 to move and raise the said coal or other suitable fuel
in the said chamber, and thereby supply the fire or part ignited, or I do, should
the same have been raised, lower it by the same means into the said chamber,
where the part ignited becomes extinguished for want of free communication
with the atmosphere. And moreover know ye, that the said means of pro-
ducing a draught or current of air at 17 and 16 do not constitute part of my
said Invention, but are only requisites in the performance thereof, the same
having been well known long since; but that the amount of my said Invention
doth consist in the constructing of fire-places and stoves in such manner as that
the fuel necessary to support or assist the combustion required shall be given
or afforded to the part or place in combustion at the lower part of or from
beneath the same, either directly, perpendicular, or in an oblique direction, and
in the lowering by the same means the said fire or part ignited into a chamber, so
that the sume shall become extinguished, and that my said Invention of certain
improvements is applicable to fire-places, stoves, &c., by which I mean any
situation whatsoever where fuel is to be successively applied or offered for the
means of supporting combustion for the purpose of heat, and as to the form,
dimensions, or construction of and in the same, they may be varied and adapted
to the situation or other circumstances governing them, and which variations
and adaptations any competent workman in works of this and the like naturo
can devise and execute.
In witness whereof, I, the said John Cutler, have hereunto sit my hand
and seal, this First day of July, in the year of our Lord One thousand
JOHN CUTLER. (L.B.)
