AN APPARATUS TO BE ATTACHED TO FIRE STOVES OF ALL DESCRIPTIONS FOR ROOMS, FOR THE REMOVAL OF CINDERS AND ASHES, AND THE BETTER PREVENTION OF DUST ARISING THEREFROM;
Year: 1812

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
RAFFIELD, of Edward Street, Cavendish Square, in the County of Middlesex,
Architect, 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 Twentieth day of
January, in the fifty-second year of His reign, give and grant unto me,
the said John Raffield, my exors, adññors, and assigns, His especial licence,
full power, sole privilege and authority, that I, the said John Raffield, my
exors, adñiors, and assigns, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "AN APPARATUS TO BE ATTACHED TO FIRE STOVES OF ALL DESCRIPTIONS
FOR ROOMS, FOR THE REMOVAL OF CINDERS AND ASHES, AND THE BETTER PREVENTION
OF DUST ARISING THEREFROM;" in which said Letters Patent there is contained
a proviso that if I, the said John Raffield, 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 enrolled in His Majesty's High Court of Chancery, within two
calendar months next and immediately after the date of the said Letters
Patent, that then the said Letters Patent, and all liberties and advantages
whatsoever thereby 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Raffield, do hereby declare that the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are particularly described
and ascertained as follows; that is to say :-
In Drawings hereunto annexed, Figure 1, A, represents a fire stove for a
room, having my said apparatus attached thereto, for the removal of cinders
and ashes, and the better prevention of dust arising therefrom; and Fig. 1, B,
represents the same stove by a projection nearly equivalent to a vertical
section upon a plane supposed to pass across the bars of the grate thereof;
and Fig. 1, C, represents the same by another projection nearly equivalent to
a vertical section upon a plane supposed to pass through a sliding bar indicated
by the letters i, h; and Fig. 1, D, represents the same by a projection nearly.
equivalent to a ground plan. And in all the said Figures the same letters of
the alphabet are used and applied to denote the same parts or things.
Letter a, denotes the bars, and b, an inclined plate, being part of my said
apparatus, which serves to receive the cinders and ashes which fall thro'
the bars, and to direct and convey the same over the top of the moving plate
d, e, f, which is another part of my apparatus, and is seen in its place of
rest or ordinary position at d, d, e, e, f, f, and in that position doth enclose.
and separate the hindmost or back part of the stove from the apartment, and
serves to conduct the said cinders and. ashes into a receptacle or vessel or
place g, g, below the level of the hearth. And the said plate is capable of
being moved from the position d, d, e, e, f, f, into that of d, e, f, by means of
centers, pivots, or an horizontal axis at c, and when at rest at d, d, e, e, f,f,.
doth cover and close the front or anterior part of the said receptacle or vessel
or place, and prevents all communication of dust or other offence into the
apartment; and when in the position d, e, f, whatever cinders or ashes may
have fallen from the front of the bars are discharged into the said receptacle,
vessel, or place. The letters g, g, represent another part of my said apparatus,
namely, a receptacle or vessel, made by preference of iron or other metal, for
receiving and retaining the cinders and ashes, and the said receptacle or vessel
can be taken out, when needful, by handles at n, n, or otherwise. In Figures
No. 1, C, and No. 1, D, the letters k, l, denote a lever or bar, moveable on the
joint l, and capable of acting against the roller or piece m, constituting the
extremity of an arm proceeding from the centre C, and by that means of
raising the plate d, e, f, or of suffering it to settle it in its lowest or quiescent
position; and the bar i, h, or any other equivalent communication, affords the
means of operating upon the, said lever by the hand whenever required.
Fig. 2, B, and Fig. 2, D, shew a variation of my said apparatus which may
in some cases be prefered for its simplicity and cheapness. Letters & represents
the part of the former moveable plate, which is here, fixed, and forms a

page_text: continuation of the plate b; and e represents the like part e of the said
moveable plate, which is here suspended by a hinge, winch, or centers at top,
and may be lifted up by bringing the same forwards; and letter f represents the
lower part f of the said moveable plate which is here movable upon a center c,
and may be opened by tilting or pressing down the nearer part with the poker
or otherwise, and the said part rises again by a moderate preponderance when
that pressure is withdrawn; and the said receptacle or vessel, together with its
plate or cornerf, can be lifted out (first raising the plate e, for the purpose
of removing the cinders and ashes whenever requisite.
And lastly, Fig. 3, A, and Fig. 3, B, and Fig. 3, D, represent another
variation of my said apparatus, in which the last-mentioned plate f, instead of
having the centres or pivots thereof supported immediately by the upper rims
of the receptacle or vessel g, g, hath the said centers or pivots supported upon
and by a frame o, o, moveable upon hinges or joints or other equivalent gear
of n, n, and by consequence thereof capable of being raised as at the dotted line
n, c, c, o, o, in Fig. 3, B, and of allowing the receptacle or vessel beneath to be
emptied or taken out without interfering with or disturbing or in any respect
clogging or injuring the plate or part f, and the fittings of the same, the back
plate or part C being movable upon an hinge joint or centers, in the same
manner as in Figure 2, B. And I do vary the dimensions and situation of the
said apparatus and the parts thereof according to the description and dimensions
of the stoves and chimney places to which the same is or are to be applied.
In witness whereof, I, the said John Raffield, have hereunto set my
hand and seal, the Nineteenth day of March, in the year of our Lord
One thousand eight hundred and twelve.
