Year: 1818

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
STYLES, of Islington; in the County of Middlesex, Carpenter, 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 Twelfth day of November, in
fifty-ninth year of the reign, give and grant unto me, the said' William Styles,
my exors, aduors, and assigns, His especial' licence, full power, sóle privilege
and authority, that I, the said William Styles, my exors, adñors, and assigns,
during the term of years therein mentioned, should and lawfully might make,
use, exercise, and vend, within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN MACHINERY FOR SIFTING
CINDERS, AND DISCHARGING THE CINDERS SO SIPTED INTO A CONVENIENT RECEPTACLE,
(WHICH MACHINERY IS APPLICABLE TO OTHER USEFUL PURPOSES;" in which said
said Letters Patent there is contained a proviso, that if I, the said William
Styles, 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 His
Majesty's 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 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
William Styles, do hereby declare that my said improvements in machinery

page_text: for sifting cinders, and discharging the cinders so sifted into a convenient
receptacle (which machinery is applicable to other useful purposes), are
described and specified in manner following:-
:-
Fig. 1 represents a perspective and transparent view of a box or bin, in
which the sieve is shewn suspended, and all its apparatus.
Fig. 2, a similar view of a box or bin, with the sieve represented in the
position for discharging the contents.
A, A, A, the boundary lines of the box or bin, a portion of which is divided
off by a partition T, for the reception of the hod or scuttle R, the remaining
part of which box or bin serves to receive what passes through the sieve.
B, B, B, a wooden sieve, with wire bottom, the front end or flap of which
C, C, is attached to the upper part of the sides by brass pins or centres, on
which (when the spur M is withdrawn) it opens.
D, D, plates of iron, by which the sieve B is suspended.
E, E, brass centers or buttons (rivetted or otherwise made fast on iron
plates), on which the sieve is suspended by the plates D, D, two of which
centers are affixed to the box or bin and two to the sides of the sieve.
F, F, a cross rail serving to strengthen and connect the frame of the sieve,
on which the hinge joint I of the lever K, and the wood stops G, G, are fixed.
G, G, two projecting pieces or wood stops, screwed or otherwise made fast
on the cross rail F, which, when the sieve is at rest, press against the front
springs H, and serve to keep the sieve at a sufficient distance from the
fulcrum L to be acted on by the lever K, when required to discharge the
sieve.
H, H, H, three springs of wood, two of which are fixed to the inside of the
front and one to the back of the box or bin, against which the sieve strikes in
the act of sifting, thereby facilitating its motion and preventing the shock from
injuring the box or bin; the two in front also serve as guides to the sieve in
taking the position for discharging.
.I, an iron-hinge or joint; fixed on the cross rail F, and connecting the lever
and handle K therewith.
K, an iron lever, with wooden handle, passing under the friction wheel L;
through the front of the box or bin c; connected with the sieve by the hinge
or joint I, serving to move the said sieve for the purpose of sifting, and also
by raising said lever to throw the sieve into the position for discharging,
represented in Fig. 2.
L, a brass friction wheel, in an iron frame, which is fixed in the front of the
box or bin, and under which the lever K passes when sifting; it also serves as
a fulcrum to the said lever in discharging the sieve.

page_text: M, an iron leg or spur, fixed to and projecting from the under part of the
lever K, which leg or spur serves to support the front end or flap C, while
sifting or at rest, and when withdrawn (by raising the said lever), the said
flap falls open and allows the discharge of the contents of the sieve.
N, a brass friction wheel at the end of the leg or spur M.
O, a wooden knuckle, fixed on the front end or flap C, which serves to delay
the opening of the said flap until the friction wheel N has passed over the said
knuckle, thereby preventing any discharge of the contents of the sieve should
the lever K be partially raised while sifting.
P, à brass friction wheel in iron frame, let into the back end of the sieve,
which, when the sieve is taking the position for discharging, passes under the
curved piece Q.
Q, a curved piece of wood, fixed to the upper part of the box or bin, under
and against which the friction wheel P passes.
R, a moveable hod or cinder box, into which the contents of the sieve are
discharged through the hopper or funnel S.
S, the funnel or hopper to conduct the discharge into the hod R.
T, the line marked thus shews a partition in the box or bin for the reception
of the hod R and hopper S.

Having thus described the nature of my said improvements, and the uses
and construction of the several parts, I observe that they may be made of any
sizes and materials that will answer the uses intended.
I also further observe, that it is the peculiar vibratory motion given to the
sieve, and the particular method of discharging the contents thereof, as effected
by means of the machinery above described, which I claim as my Invention.
In witness whereof, I, the said William Styles, have hercunto set my
hand and seal, this Ninth day of January, in the year of our Lord
One thousand eight hundred and nineteen.
WILLIAM (L.S.) STYLES.
