Sealed the 2nd February 1866, and dated the 13th October 1865.
PROVISIONAL SPECIFICATION left by the said William Halse Gatty
Jones at the Office of the Commissioners of Patents, with his Petition,
on the 13th October 1865.
I, WILLIAM HALSE GATTY JONES, of Crosby Square, in the City of
London, Solicitor, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY EMPLOYED FOR CRUSHING, AMALGAMATING, AND
WASHING GOLD QUARTZ AND OTHER MINERALS OR MATTERS CONTAINING GOLD OR
OTHER METAL," to be as follows:-
This Invention has for its object improvements in machinery employed
in crushing, amalgamating, and washing gold quartz and other minerals or
matters containing gold or other metal. For those purposes a cylinder is
employed, supported in such manner that it may be caused to revolve freely,
and this is most conveniently done by supporting such cylinder on wheels
or rollers, but it may be otherwise supported. At one end of this cylinder
is an opening through which the end of a shoot or trough enters, and by

page_text: which the broken quartz or mineral or matter is conducted into the interior
of the cylinder. The other end of the cylinder is formed with a central
opening, through which the crushed and separated matters pass away into
another cylinder of somewhat smaller diameter than the principal cylinder,
to which it is fixed concentrically. The outer end of this smaller cylinder
has an opening out of it somewhat larger than the opening above mentioned
in the end of the,principal cylinder. Within the large or principal cylinder
is another heavy cylinder, which is open at both of its ends, and it is
perforated with holes in order that the broken and crushed materials may
pass through such perforations. This inner cylinder is somewhat shorter
than the interior of the larger or principal cylinder, so that as the larger
cylinder is caused to revolve the interior cylinder is also caused to revolve;
but as the inner heavy cylinder is free; it at all times remains pressing on
the part of the outer or principal cylinder which for the time is at the lowest
position; hence the material to be crushed will be pressed between the
inner surface of the principal cylinder and the outer surface of the smaller
heavy cylinder. Mercury when used is placed in the principal cylinder,
so as to come so far up towards the central outlet in the end of the princi-
pal cylinder that when the refuse floats on the mercury such refuse may
fall out or pass out into the smaller cylinder, and this may be facilitated
by a current of water, and should any heavy matter escape it will be
returned back by the smaller cylinder fixed to the end of the larger
cylinder. In some cases only water is used, and in other cases the
machine is used without mercury or water.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Halse Gatty Jones in the Great Seal Patent
Office on the 12th April 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HALSE GATTY JONES, of Crosby Square, in the City of London, Solicitor,
'send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of October, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto ime, the said William Halse Gatty Jones, Her special licence that I, the
said Williain Halse Gatty Jones, ny executors, administrators, and assigns, or

page_text: such others as I, the said William Halse Gatty Jones, my executors, adminis-
trators, 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 King-
dom of Great Britain and Ireland, the Channel Islands,, and Isle of Man,
an Invention for "IMPROVEMENTS IN MACHINERY EMPLOYED FOR CRUSHING, AMAL-
GAMATING, AND WASHING GOLD QUARTZ AND OTHER MINERALS OR MATTERS
CONTAINING GOLD OR OTHER METAL," a communication to me from abroad
by the Inventor, James Hart, of the City of Melbourne, in the Colony of
Victoria, Engineer, upon the condition (amongst others) that I, the said
William Halse Gatty Jones, my executors or administrators, by an instru-
ment 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 William Halse Gatty Jones, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say:-
This Invention has for its object improvements in machinery employed
in crushing, amalgamating, and washing gold. quartz and other minerals or
matters containing gold or other metal. For these purposes a cylinder is
employed, 'supported in such manner that it may be caused to revolve.
freely, and this is most conveniently done by supporting such cylinder on,
wheels. or rollers, but it may be otherwise supported. At one end of this
cylinder is an opening through which the end of a shoot or trough enters,
and by which the broken quartz or mineral or matter is conducted into
the interior of the cylinder. The other end of the cylinder is formed with
a central opening, through which the crushed and separated matters pass
away into another cylinder of somewhat smaller diameter than the principal
cylinder, to which it is fixed concentrically.. The outer end of this smaller
cylinder has an opening out of it somewhat larger than the opening above
mentioned in the end of the principal cylinder. Within the large or prin-
cipal cylinder is another heavy cylinder, which is open at both of its ends,
and it is perforated with holes in order that the broken and crushed
materials may pass through such perforations. This inner cylinder is some-
what shorter than the interior of the larger or principal cylinder, so that as
the larger cylinder is caused to. revolve the interior cylinder is also caused

is at the lowest position; hence the material to be crushed will be pressed
between the inner surface of the principal cylinder and the outer surface
of the smaller heavy cylinder. Mercury when used is placed in the prin- .
cipal cylinder, so as to come so far up towards the central outlet in the end.
of the principal cylinder that when the refuse floats on the mercury such
refuse may fall out or pass out into the smaller cylinder, and this may be
facilitated by a current of water, and should any heavy matter escape it
will be returned back by the smaller cylinder fixed to the end of the
larger cylinder. In some cases only water is used, and in other cases the
machine is used without mercury or water.
Having thus stated the nature of the Invention, I will proceed more fully.
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a side elevation, Figure 2 shows a plan, Figure 3 shows
an end view, Figure 4 shows a longitudinal section, Figure 5 shows a
transverse section; and Figure 6 shows the end elevation opposite that'
represented in Figure 3.
A and B represent the ground flooring or standard and cross logs to
which the framework of the machine is fixed; C, C, show the four posts of
the framing, and D, D, the end or transverse timbers; T, T, are two iron
shafts supported in blocks S fitted to the corner posts; U, U, are four
rollers fitted on the shafts T, T, and which confine the outside cylinder K,
which is composed of iron or steel; G, G, are four blocks or bearings
>resting on the cross bearers B, and they are secured to them by the bolts
H; in these blocks or bearings the main shaft I works; J, J, are two
>wheels or rollers attached to and working on the main shaft I, on which the
outer cylinder K rests; R is a shoot or hopper supported by two uprights
E, E, as shown, by which the materials are fed into the machine; M is one
end of the outside cylinder K; and N is a short conical mouthpiece fixed
on the end M, into which the end of the shoot or hopper R is introduced,
and by which the quartz or other materials to be operated upon are con-
ducted into the machine; W is a tap hole or opening in the cylinder K,
through which it is cleaned out; X, X, are two belts round the outside
cylinder K, driven by the pulleys Y, Y, on a shaft Z, which is driven by a
steam engine or other motive power; P is a short cylinder fixed to the
other end O of the outside cylinder K. In the centre of the end of the

page_text: cylinder P is a conical lip Q. A quantity of mercury having been placed
inside the cylinder K, the quartz or other materials to be operated upon are
conducted through the shoot or hopper R, accompanied by a sufficient
stream of water, into the cylinder K, motion having been imparted to that
cylinder by means of the driving belts X, X, or it might be by other suit-
able gear. The quartz or other material to be operated upon so introduced
into it as above stated, coming between its interior surface and the exterior
surface of the inside cylinder L (which rolls or revolves inside the outer
cylinder), becomes finely crushed, and the particles when sufficiently
reduced, with the exception of the metallic substances therein (which
become amalgamated with the mercury and remain inside and at the lower
part of the cylinder), are carried out of the outer cylinder K by the current
of water into a suitable receptacle for further treatment if desired, the
heavier metallic matters, if any are carried over, remaining in the short
cylinder P. When desired the material to be operated upon can be
crushed without the use of mercury or water.
Having thus described the nature of the Invention, and the manner of
performing the same, I would have it understood that I do not confine
myself to the precise details so long as its character be maintained; but
what I claim is the combined arrangement of the cylinders K, L, and parts
O, P, Q, constructed and working substantially as herein described.
In witness whereof, I, the said William Halse Gatty Jones, have here-
unto set my hand and seal, this Fifth day of April, in the year of
our Lord One thousand eight hundred and sixty-six.
