WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-fourth day
of January, One thousand eight hundred and fifty-two, in the fifteenth
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Kent, my exors, adñors, and assigns, Her especial license,
full power, sole privilege and authority, that I, the said George Kent, my exors,
admors, and assigns, or such others as I, the said George Kent, my exors,
adiňors, 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, the Invention of "CERTAIN IMPROVE-
MENTS IN APPARATUS FOR SIPTING CINDERS AND IN APPARATUS FOR CLEANING
KNIVES;" in which said Letters Patent is contained a proviso that I, the
said George Kent, shall cause a particular description of the nature of the said
Invention, and in what manner the same is to be performed, by an instru-
ment in writing under my hand and seal, 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
George Kent, do hereby declare the nature of my said Invention, and in what
manner the same is to be carried into effect, are fully described and ascer-
tained in and by the following description thereof, reference being had to the
Drawings hereunto attached, and to the figures and letters marked thereon,
that is to say:
The Invention relates, first, to apparatus for receiving cinders and separating
the larger parts, which may be again used as fuel, from the smaller parts or
dust which are unfit for fuel.
And, secondly, my Invention relates to means of supporting the pieces of 1
leather affixed to the sides of the discs used in my rotary knife cleaner.
In order that the Invention may be fully understood and readily carried into
effect, I will now proceed to describe the Drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shews an external view, Figure 2 an end view, Figure 3 a
longitudinal section, and Figures 4 and 5, transverse sections of apparatus
according to the first part of my improvements, and which consist of a hopper
in which the refuse from the fire-places are first placed, thence they pass into
the perforated cylinder, which, when set in motion, separates the larger parts
from the small and dust, the dust falling through into a lower chamber, whilst
the larger lumps are thrown forward into a receiver placed in front to receive
them. The parts are for the most part enclosed in a sort of box, which is
divided into two parts a, b, capable of being separated; the part a being the
lower; and is for the purpose of receiving, and for a time retaining, the small
ashes or dust thrown out in the act of separation effected by the working of
the apparatus; the part 6 contains the principal parts, which I will now
describe. c is the trough into which the cinders and refuse to be separated
are placed; it has a cover d, and an inclined bottom e, to conduct the matters
through the opening f into the perforated cylinder g, which it will be seen has
no supporting axis passing through it, but is supported externally at each end
upon rollers h, h, so as to be capable of rotating, whilst the interior is free of
any axis to impede the free passage of the cinders, and other refuse matters
therein. The perforated cylinder I by preference form of perforated zinc or
galvanised iron, the ends of which are fixed to the metallic rings g', g', upon
one of which is formed the tooth surface or wheel g', by which rotary motion is
given to the cylinder g, such tooth surface taking into the pinion i, fixed upon
the axis, upon which is affixed the crank handle j, by turning which rotary
motion will be given to the cylinder 9 ; and to facilitate the separation of the

page_text: matters as they pass through the cylinder g, there are affixed in that cylinder
the tooth apparatus g', and to distribute the dust and loose particles as they
pass from and accumulate under the cylinder g, there is affixed to the
cylinder g, the bar g', which, as the cylinder rotates, prevents the matters
remaining in contact with that cylinder, and thereby impeding the further
passage therethrough. The larger parts which do not pass through the
perforation of the cylinder fall through the opening k, and are received into
the receiver, which I prefer to be of the form shown, and is supported by its
ears being hung on the projections m, m. n, n, are handles to the parts
a, b, and o is a handle to the part l.
I will now describe the second part of my Invention, which is shewn by
Figures 6 and 7. I have not thought it necessary to show one of my rotary
knife cleaners entire, as they are described in a former Patent granted to me,
and I have therefore only shewn one of the rotary polishing discs, to which
alone the present improvements apply. Heretofore, in forming such rubbing
or polishing surfaces, in order to give elasticity to the strips of leather, I applied
rows of bristles at the back of such strips. But I have found that the strips
of leather do not act uniformly on the knives to be cleaned, and those strips
are worn away unequally; and my present improvements under this head of the
Invention consists in substituting for such rows of bristles as supporting means
strips of india-rubber (by preference vulcanised); p, p, are the strips of leather
for the purpose of producing the cleaning and polishing on the knives, and q, q,
are the strips of india-rubber for giving elastic support to those strips of leather.
These strips p and q are retained in position by means of the strips of
wood r.
Having thus described the nature of my Invention, and the manner of
carrying the same into effect, I would have it understood that I do not confine
myself to the precise details herein described, so long as the peculiar character
of either part of the Invention be retained; but what I claim is,
First, the means herein described of arranging apparatus for sifting cinders.
And, secondly, I claim the applying india-rubber as a supporting means to
the strips of leather employed to clean and polish knives in apparatus such
as above referred to.
In witness whereof, I, the said George Kent, have hereunto set my hand
and seal, this Twenty-fourth day of July, One thousand eight hundred
and fifty-two.
GEORGE (L.S.) KENT.
