I, GEORGE HENRY GOODMAN, of No. 53, Penrose Street, in the Parish
of Saint Mary, Newington, in the County of Surry, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY FOR
CRUSHING, GRINDING, AND TRITURATING STONE, MINERALS, ORES, AND QUARTZ;
ALSO FOR WASHING AND SEPARATING METALS FROM ORES%; AND FOR WASHING,
SEPARATING, AND AMALGAMATING GOLD FROM QUARTZ," to be as follows:-
This Invention consists and has for its object in, one compound
machine a combined and efficient means to crush, grind, and triturate
stone, minerals, and ores; also to wash and separate metals from ores;
and to wash and amalgamate gold from quartz.
.
My Invention consists essentially of an horizontal ram, the head or
acting face being curved and serrated obliquely, not vertically. Hori-
zontally through the head end of the ram there is a hole or boss, through
which an eccentric passes loosely. The journals of the eccentric has its
bearings in the sides or cheeks of machine, and is put into motion by

page_text: suitable gear, giving a kind of rolling action to the ram, which at one
and the same time performs a distinct crushing and grinding action upon
the material being reduced, the ram giving and receeding to and from
the block or face of chilled iron stationery fixed at the head of the
machine opposite to the face of the ram; this block or face is also curved
and serrated obliquely, performing a cross grip, the serrations being in
contradistinction when placed face to face, the tail or back end of the
ram being made with a slot or fork, in which a sliding bearing is made
to work loosely; through this bearing a spindle passes (also loosely) and
the journals, stayed by bearings, securing equilibrium to the working of
the ram, the material falling through the bottom passes over a vibrating
sieve with an attached shoot for the purpose of conveying the material
to the amalgamating dish after having passed through the sieve, the
courser material being conveyed to the triturating mill, the triturating
mill being two horizontal discs. (I am aware that horizontal disc mills
are old) but I claim improvements in the construction of lands and
furrows for the production of fine grinding, and method of replacing
parts most exposed to wear; also a contrivance to admit courser
material into the discs, namely, two serrated conical rings made to be
movable; also improvements in the construction of movable furrows,
by which means, namely, the coarse material in being made to pass
through the mills is finally reduced to powder, and is thrown into the
amalgamating dish; this dish has two compartments similar to two dishes
placed one into another; the inner dish contains the triturating mill, the
outer dish containing amalgam or quicksilver, and which is at all times
kept overflowing with water. The pulverised matérial being con-
stantly ground into the amalgamating dish is kept constantly stirred
by means of an arm or router attached to the revolving disc, the mud
and shingle or tailings flowing off with the water (if preferred into a
sluice) thus forming a whole and efficient means in one combined
machine to crush, grind, pulverise, wash, and separate metals from ores,
and wash and amalgamate gold from quartz.
