WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of September, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Richard Martyn, William Williams Martyn,
William Charles Trevena, and Thomas Henry Harry, Her special licence
that we, the said Richard Martyn, William Williams Martyn, William
Charles Trevena, and Thomas Henry Harry, our executors, adminis-
trators, and assigns, or such others as we, the said Richard Martyn,
William Williams Martyn, William Charles Trevena, and. Thomas
Henry Harry, our 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 In-
vention for "AN IMPROVED WHEEL BUDDLE POR DRESSING OR SEPARATING
TIN ORES, AND ORES OF ALL METALS, AND ORE WHICH IS HELD IN SUSPENSION IN
WATER AND EARTHY SUBSTANCES," upon the condition (amongst others)
that we, the said Richard Martyn, William Williams Martyn, William
Charles Trevena, and Thomas Henry Harry, our executors or adminis-
trators, by an instrument in writing under our, 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 we, the said Richard Martyn, William
Williams Martyn, William Charles Trevena, and Thomas Henry Harry,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of this our Invention of "An Improved Wheel Buddle for
Dressing or Separating Tin' Ores, and Ores of all Métals, and Ore which
is held in Suspension in Water and Earthy Substances," is to use the.
ore and water to be dressed as the motive power for dressing and dis-

page_text: tributing itself on the surface of the buddle, thereby effecting economy
in the apparatus necessary for dressing, and being self-acting dispensing
with the cumbrous and expensive machinery generally used for com-
municating motion to buddles at present in use. This buddle is
particularly adapted for separating ores from slimes and streams, as it
can be applied where there is only water sufficient for dressing and a
very slight fall in the stream under treatment.
It is a fact well known to all engaged in the dressing of ores (especially
tin ores) that large quantities escape in the streams and rivers. The use
of this buddle tends to reduce the waste in dressing to a minimum, also
to economise expense and labour, and to obviate the liability to accidents
to work people engaged in dressing.
A buddle constructed according to this our Invention consists of a
vertical shaft or perpendicular bar fixed at its bottom end to the centre
of the ordinary buddle head. This vertical shaft or bar acts as axle
for a perforated distributor pan or basin, the diameter of which
it is preferred should be about three feet, and the depth about
twelve inches. This distributor pan revolves horizontally freely on
the before-mentioned axle. Firmly attached to the upper end of this
shaft is a vertical metal or wooden frame. This frame extends from the
vertical shaft (which is in the centre of the distributor) to the outer
edge or rim of the distributor pan, and carries a horizontal shaft, upon
which shaft is fitted a dwarf water wheel, which revolves vertically
within the distributor pan. (This wheel must be made of size to suit
the distributor pan.) This horizontal shaft also carries a pinion wheel,
which pinion gears into a toothed wheel, which is fixed or attached
round the circumference of the upper edge of the distributor pan or
basin. A pipe or launder is fixed above the top or near the bottom of
the water wheel to conduct the water and ore to be dressed, which
passes through the pipe, falls into the buckets of the water wheel,
and sets the apparatus in motion, namely, the water wheel, revolving
by the weight of the ore. and water causes the pinion on the same
shaft to work into the geared wheel on the upper edge of the circum-
ference of the distributor, thereby causing the distributor to revolve
freely round the vertical shaft forming its axis. Attached to the
sides of the perforated distributor are horizontal arms, which arms
have suspended from them brushers which act upon the water and ore

page_text: on the surface of the buddle. The water and ore fall from the buckets
of the water wheel into the perforated distributor pan or basin, thence
escape through the perforations or holes down the surface of the buddle,
and are treated by the brushers.
It will be obvious that the speed of dressing by the use of this buddle
is regulated by the supply or quantity under treatment.
In order that the nature and action of this Invention may be more
readily seen and understood, we have hereunto attached Drawings,
illustrating so much of an apparatus constructed according to our
Invention as will enable any ordinary mechanical engineer to carry the
same into practical effect. Like letters marked on the Drawings are
used to denote similar parts throughout the various Figures.
Figure 1 is a sectional elevation of a buddle constructed according to
our Invention; Figure 2 is an outside elevation of the same; Figure 3
is a plan of the same; and Figure 4 is a sectional elevation of a modi-
fication of the same.
A, buddle head, to which is attached B, vertical shaft, which carries
and forms axis to C, perforated distributor pan; D, frame attached to
top of vertical shaft B, and carrying E, horizontal shaft, upon which is
fitted F, water wheel, revolving partially within the distributor pan C;
G, pinion keyed on to shaft E, and gearing into H, toothed wheel on
upper circumference of distributor pan C; I, distributor arms; K, brushers
attached to same; L, pipe or launder; M, perforations or holes in
distributor pan C.
The ore and water to be dressed flows through the pipe or launder L,
thence into the buckets of the water wheel F, causing the same to
revolve, and thereby imparting rotary motion to the distributor pan Ċ by
means of the pinion G. The ore and water are emptied from the
buckets of the water wheel F into the distributor pan C, which as it
revolves distributes the ore and water over the surface of the buddle A,
where it is acted upon by the brushers K.
Having now fully described and explained the nature and purposes of
our Invention, and how the same is to be carried into practical effect,
we wish it to be clearly understood that we do not confine ourselves to
the several proportions and relative dimensions of the various parts of
the apparatus, as shown, as it will be readily seen that the same may be

page_text: considerably varied without departing from our Invention; but what
we claim as the Invention secured to us by Letters Patent aforesaid
is, the construction, arrangement, and combination herein shown con-
stituting a wheel buddle, substantially in the manner and for the
purposes herein-before described, set forth, and illustrated.
In witness whereof, we, the said Richard Martyn, William Williams
Martyn, William Charles Trevena, and Thomas Henry Harry,
have hereunto set our hands and affixed our seals, this First day
of March, in the year of our Lord One thousand eight hundred
