page_text: LETTERS PATENT to Joseph Kaye Hampshire, of the Parish of Whit-
tington, in the County of Derby, Civil Engineer, for the Invention
of "IMPROVEMENTS IN APPARATUS OR MACHINERY FOR WASHING COAL,
COAL SLACK, AND OTHER MINERAL SUBSTANCES, AND SEPARATING FOREIGN
PARTICLES THEREFROM.".
Sealed the 6th April 1863, and dated the 7th October 1862.
PROVISIONAL SPECIFICATION left by the said Joseph Kaye Hampshire at
the Office of the Commissioners of Patents, with his Petition, on the
7th October 1862. .
:
I, JOSEPH KAYE HAMPSHIRE, of the Parish of Whittington, in the
County of Derby, Civil Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN APPARATUS OR MACHINERY FOR WASHING
COAL, COAL SLACK, AND OTHER MINERAL SUBSTANCES, AND SEPARATING FOREIGN
PARTICLES THEREPROM," to be as follows:-
The improvements consist of, first, the introduction of a toothed roller or
rollers for breaking the coal to a proper size.
Secondly, a simple method of agitating the water by a dasher plate.
Thirdly, the introduction of metal grate bars so constructed that à continuous
stream of water is made to act with great force upon the coal, coal slack, or
other minerals in the purifying chamber.
Fourthly, a ready and efficient mode of carrying away the refuse and
impurities as separated from the coal by the process of washing.

page_text: The machine is represented in the annexed Drawing shewing side view
thereof, except the two toothed rollers, which are placed above the hopper A,
and worked by wheel B. The coal is raised upon an elevated platform, and
passes through the toothed rollers before-mentioned, and falls into hopper A,
whence it passes through apertures R into the purifying chamber F, in which
the metal grate bars are fixed, and through which grate bars a strong current
of water is continuously forced by a dasher plate G within dasher chest C;
it is mounted and works on a shaft H, passing through a stuffing box D in
dasher chest. The dasher plate is worked by a lever L from shaft H by an
eccentric on shaft N.
The process of agitation separates the coal from all foreign substances, and
causes it to rise over the front of chamber F, where it falls on an inclined
spout E, and is conveyed into suitable waggons or trucks for removal to coke
ovens or otherwise. The slate and other foreign and extraneous substances
settle on the grate bars, and are removed through a sluice P, and pass away
by a valve T at the bottom of dasher chest. C. The water is supplied and
regulated through pipes M.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Kaye Hampshire in the Great Seal Patent Office on
the 7th April 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
KAYE HAMPSHIRE, of the Parish of Whittington, in. the County of Derby,
Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of October, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-sixth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Joseph Kaye Hampshire, Her special licence that I, the said Joseph Kaye
Hampshire, my executors, administrators, and assigns, or such others as I, the
said Joseph Kaye. Hampshire, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN APPARATUS OR MACHINERY FOR WASHING COAL, COAL SLACK, AND OTHER
MINERAL SUBSTANCES, AND SEPARATING FOREIGN PARTICLES THEREFROM," upon
the condition (amongst others) that I, the said Joseph Kaye Hampshire,

page_text: my executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Joseph Kaye Hampshire, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Sheet of Drawings here-
unto annexed, and to the letters and figures marked thereon (that is to
say):-
My Invention relates to improvements in apparatus or machinery for
washing coal, coal slack, and other mineral substances, and separating foreign
particles therefrom, which improvements consist, 1st, in the application of a
pair of toothed rollers for reducing the coal or other mineral substances to be
operated on to a uniform size, as nearly as may be,, before being introduced
into the washing apparatus, which facilitates the washing operation and the
separation of the foreign extraneous or refuse matters from the coal or
matters being washed.
2ndly, in the application of an oscillating plate or surface for the agitation
of the water to produce the washing operation.
:
3rdly, in the application of a series of metal grate bars for the support of
the materials being washed, so arranged as to permit the water to act with great
force on the materials being washed, and so as to admit of, and provide for the
escape thereof after a sufficient treatment in the washing or purifying chamber.
4thly, in the arrangements for the removal or passing away of the impurities
separated from the coal or other minerals being washed.
..
'. In washing coals and other minerals which are operated on in large
quantities I provide suitable rails or ways and trucks to bring the minerals
to the machine at such an elevation that the materials may be allowed to
descend and pass through the several operations and then be received in trucks
placed on rails or ways at a lower and suitable elevation, and be conveyed
away to the heap or other store or depository. In this way I deliver the
coals or other materials from a truck into a receiving hopper at a suitable
elevation; from this hopper they pass on to and between the breaking rollers,
falling from which they are received into a second hopper, from the lower part
of which they pass into the washing or purifying chamber, and from which they
pass by a' suitable spout into the receiving trucks separated from extraneous

page_text: or refuse matters, and thence away to the coke ovens or other destinations
for which the matters operated on may be intended.
DESCRIPTION OF DRAWINGS.
Fig. 1 represents a side elevation of a double machine constructed according
to my Invention; Fig. 2 a plan of the same, while Fig. 3 represents on the
left hand an end view of the washing or purifying chamber, and on the right
a section of the other washing or purifying chamber, also the dasher and
agitating chamber taken through the line 1, 2, Fig. 1.
a, a, is the hopper receiving the coals or other minerals from the trucks b
mounted and running on rails c from hopper a, the coals fall on a shoot d
which is hinged or supported on an axis e at the upper end, and hangs by. a
rod fat. the other, which rod f communicates. an up-&-down motion to the
shoot d from an eccentric g on rotating shaft h, so as to cause a uniform or
nearly uniform delivery of the coals from the lower end of the shoot d, which
in itself has not such an inclination as to cause the coals to run freely without
such, shaking motion; from shoot d the coals fall and pass between two
sharp-toothed rollers i, i, (seen dotted) which gear together in the manner of
spur gearing, and which may be further connected by spur wheels on the
ends of their shafts. These rollers i, i, should be approached and adjusted in
such proximity to each other as to suit the required reduction of the matters
to be passed between them. These rollers are of cast iron or other metal
suitable for the mineral to be operated on, and of a strength in proportion
to the hardness and difficulty of breaking such material. From rollers i the
crushed materials, fall into the hopper k, and from thence pass by sluices or
openings 1, 1, and fall into the washing chamber ;. in this chamber they are
received and supported on the grated bars m, m, during which they undergo
the operation of washing. p, p, p, p, are chambers containing water, each pair
opening into their respective dasher chambers g, the water in such chamber p
being about or above the level of the grated bars m, m, so that when thrown
up it runs over the spout w (about 8 inches above the grated bars) in
front to carry off the clean slack; r is the dasher, (see edge view Fig. 4), being
a plate fixed on shafts passing through a stuffing box in the side of chamber q;
this plater nearly fills the area of the cross section of the dasher chamber q
and with just sufficient clearance to work freely therein. The shaft has
an arm keyed on it, which arm is in communication with an eccentric rod t, from
which it receives a to-and-fro movement communicated by the eccentric u
fixed on the rotating shaft v; by this means the dasher plate r is caused to
perform an oscillatory movement which throws the water contained with great

page_text: force alternately into the two opposite compartments of the washer, causing the
water to rise up through the bars m,m, with considerable force, whereby it agitates
the coals supported on those bars and so separating the extraneous or refuse
matters from the coal, which extraneous or refuse matters either descend
amongst the water to the lower part of the washing chambers or accumulate
on the bars m, m, from which they are removed from time to time. The
coals by the action of the water are carried from the point of their entrance
on bars m towards the spout w, and are during that time thrown upwards
by the upward' force of the water which produces the washing action, and
are ultimately thrown over into the spout w by the action of the water in
a washed and purified state; falling thence into trucks a to be conveyed away.
The heavy refuse matters collected on the bars m, m, are removed through sluice
doors Y, which are raised by hand levers z, z; the supply of coals from hopper k
is suspended at the time, and the action of the machine 'being continued the
refuse matters will be readily thrown off. The refuse or extraneous matters
deposited at the bottom of the washing chambers I permit to escape from
time to time by a bent tube and oblong porthole A, shown dotted, closed by
a valve B connected with a weighted cranked lever C. On the axis of the
cranked lever C, I affix the band lever D to open the valve from time to time
as required, which allows the escape of a proportion of the water contained
as also the refuse or extraneous matters. In case of accumulation of refuse
matters in the lower parts of the washing chanbers that will not pass away
with the water escaping at valve B, I provide man-holes E for the removal
of the same from time to time as may be necessary, or for the repair of the
machine. F is the hydraulic main for the supply of water to the washing
machine; from this are stand pipes G with suitable stop-cocks H, such pipes
opening into the washing chambers a little below the grated bottoms m, m,
by which stop-cocks H, I admit and regulate the supply according to require-
ments and the quantity allowed to pass away by pipe B. is the driving
shaft of the machine receiving motion by a strap rigger L fixed thereon from
any suitable power. On the other end of shaft vis fitted the eccentric u,
transmitting motion as before described to shaft s. Common to both dashers r
another rigger P is fixed on shaft v, a strap R from which communicates
motion to a rigger S fixed on shaft T of the crushing rollers i, the shaft h of
which receives motion as before described, and actuates the eccentric g, rod f,
and shoot d.
In the description of Drawing I have mentioned coals only, but other -
mineral substances may be similarly treated for the purpose of washing or
separating foreign or refuse matture therefrom

page_text: Having described the nature of my Invention, and the manner of performing
the same, I declare that what I claim as my Invention to be protected by the
herein-before in part recited Letters Patent is, the arrangement and applica-
tion of apparatus as herein-before described for washing coals and other
mineral substances in order to separate them from foreign' or refuse matters or
particles.
In witness whereof, I, the said Joseph Kaye Hampshire, have here-
unto set my hand and seal, this Fourth day of April, in the year
of our Lord One thousand eight hundred and sixty-three.
