page_text: LETTERS PATENT to George Henry Goodman, of 53, Penrose Street,
Walworth, in the Parish of Saint Mary Newington, in the County
of Surrey, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
BREAKING STONE AND OTHER MATERIAL FOR ROAD MAKING, CONCRETE, AND
OTHER PURPOSES; ALSO FOR CRUSHING AND REDUCING EMERY, MINERALS, AND
ORES, AND EVERY DESCRIPTION OF HARD AND BRITTLE MATERIAL; ALSO FOR
CRUSHING AND TRITURATING QUARTZ, AND FOR AMALGAMATING OR EXTRACTING
GOLD THEREFROM."
Sealed the 6th February 1872, and dated the 10th August 1871.
PROVISIONAL SPECIFICATION left by the said George Henry Good-
man at the Office of the Commissioners of Patents, with his
Petition, on the 10th August 1871.
I, GEORGE HENRY GOODMAN, of 53, Penrose Street, Walworth, in the
Parish of Saint Mary Newington, in the County of Surrey, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINERY
FOR BREAKING STONES AND OTHER MATERIAL FOR ROAD MAKING, CONCRETE, AND
OTHER PURPOSES; ALSO FOR CRUSHING AND REDUCING EMERY, MINERALS, AND
ORES, AND EVERY DESCRIPTION OF HARD AND BRITTLE MATERIAL; ALSO FOR
CRUSHING AND TRITURATING QUARTZ, AND FOR AMALGAMATING OR EXTRACTING GOLD
THEREPROM," to be as follows:-
This Invention consists essentially of a club-headed squeezer mounted
loosely on an eccentric, which eccentric when made (by any suitable

page_text: means to rotate) gives to the said squeezer a peculiar crushing and
grinding action; the squeezer is also made to contain one or two acting
faces, the faces being curved and serrated crossways at an angle of
about 45° (forty-five) degrees. The aforesaid eccentric receives its
bearings in an iron frame of great strength in which the squeezer is
also made to act upon the material to be reduced, forming also a
fulcrum for the squeezer to exert its active force, and is made to contain
a fixed block or face or faces made similar to the active faces already
described in the squeezer, being curved and serrated and in contra-
distinction when placed opposite to the acting faces, thus reducing the
material between the fixed and acting faces.
Attached to the squeezer is an arm, the extreme end of which is made
to move loosely in or over a stay bar or any suitable contrivance for con-
venience having for its object to give or to secure a steady action to the
acting faces, the crushed material falling from between the acting and
fixed faces falls into and travels over a sieve made to vibrate, the coarse
material being discharged into and is ground or triturated into powder
between circular horizontal surface plates similar to disc mills in common
use, varying only in the construction of the acting faces, which novelty
comprises a means for reducing gold quartz to very fine powder, and
further facilitates the amalgamation or extraction of gold therefrom.
My improvements consisting of moveable furrows and the introduction
of chambers formed in the bottom surface plate; these chambers are
filled with quicksilver, over which the ground quartz passes, accom-
panied with a constant supply of water, the quicksilver absorbing the
gold, while the tailings is thrown off and passes by means of brushes
over a circular plate, also containing quicksilver, and is finally
discharged into a sluice.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Henry Goodman in the Great Seal Patent 30
Office on the 10th February 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HENRY GOODMAN, of 53, Penrose Street, in the Parish of Saint Mary
Newington, Walworth, in the County of Surrey, send greeting.

Goodman, 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 "IMPROVEMENTS IN MACHINERY FOR BREAKING STONE AND OTHER
MATERIAL FOR ROAD MAKING, CONCRETE, AND OTHER PURPOSES; ALSO FOR
CRUSHING AND REDUCING EMERY, MINERALS, AND ORES, AND EVERY DESCRIPTION
OF HARD AND BRITTLE MATERIAL; ALSO FOR CRUSHING AND TRITURATING QUARTZ,
AND FOR AMALGAMATING OR EXTRACTING GOLD THEREFROM," upon the condition
(amongst others) that I, the said George Henry Goodman, my executors
or administrators, by an instrument in writing under my, or their, or
one of their hands and scals, 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 Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Henry Goodman, 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 Drawings here-
unto annexed, and to the figures and letters marked thereon, that is
to say:-
My Invention consists essentially in certain arrangements of machinery
by which means ores, stones, and chemicals can be effectually and
efficiently crushed and ground or pulverized, and at the same time gold
extracted from quartz, by the combination of a peculiar crushing or
chewing and grinding action, such objects being effected by the employ-
ment of a club-headed squeezer mounted loosely on an eccentric, and
by an arrangement of moveable furrows and quicksilver chambers in the
faces of the mill or triturator, together with an amalgamating dish.

page_text: In order that my said Invention should be fully and essentially
described and carried into effect, I will proceed to describe the Drawing
hereunto annexed.
Fig. 1 is a longitudinal sectional clevation of the whole apparatus
combined, A being a club-headed squeezer mounted loosely on an
eccentric B, which eccentric is made to rotate by any suitable powerful
combination of mechanism, causing the said squeezer to operate upon
the material with a peculiar roundabout or rotary motion, whereby
distinctly crushing and grinding at one and the same time, also securing
a remedy against all danger from breakage, frequently caused by the
momentum of a sudden and direct giving and receding action of other
active faces now in use. The said eccentric receives its bearings in
an iron frame of great strength C, C, which also comprises a box in and
against which the squeezer exerts its active force, the squeezer being also
so constructed as to receive one or, if preferred, two active moveable
faces D, D, which may be readily understood by reference to Fig. 2.
These faces are also held in position by clips or by any other suitable
means, the face or faces being cast in hard chilled iron, and are also
curved and serrated obliquely, and act against a block or blocks, or
against a face or faces N, N, placed opposite to the said active face or
faces. These faces are also constructed and arranged to admit of being
regulated or placed in any required position; they are also curved and
serrated obliquely, the serrations crossing each other in opposite faces.
Attached to the squeezer is also a tail or arm E, the end of which is
furnished with means for a stay or guide bars, or any suitable stay
placed in any direction, or at any desired angle or point, the object
being to give any desired position, equilibrium, or stay to the squeezer.
Over the active and stationary faces is placed a hopper F, into which
the material to be reduced is thrown, and having been partly reduced
passes
into a sieve or shoot into the hopper of the mill or triturator G,
where the material is finally reduced to powder.
The novelty of the mill or triturator consists in the construction of
moveable furrows in the faces of the circular discs, in which instance
the lands and furrows are both wide. In these discs are made gaps of
considerable depth H, wherein I place duplicate pieces fixed tightly or
cemented, the object being to effect an equal long and lasting wear.
In the lands of these discs I construct deep chambers K; these
chambers are intended to be filled with quicksilver, the object being to

page_text: absorb or amalgamate gold from quartz while being ground, and con-
ducted between the discs to the amalgamating dish L, which dish is
also made to contain quicksilver, into and over which the crushed
quartz or tailings containing gold, which might have escaped the
chambers, is made to pass, being brushed and stirred with the quick-
silver by means of brushes or routers M, M, by which means the
precious metal is extracted and amalgamated with the aforesaid quick-
silver, while the tailings or crushed quartz, minus gold, is thrown off
into a sluice or cradle.
Having thus described the nature of my said Invention, and in what
manner the same is to be performed, I would have it understood that I
claim, improvements in machinery for breaking stone and other material
for road making, concrete, and other purposes; also for crushing and
reducing emery, minerals, and orcs, and every description of hard
and brittle material; also for crushing and triturating quartz, and for
amalgamating or extracting gold therefrom.
I also claim to be the author and constructor of the herein described
club-headed squeezer; its entire formation, arrangement, and manner
of working the same; also for the arrangement and construction of
moveable or duplicate furrows; and the idea and construction of quick-
silver chambers in the lands of the mills or triturators; and of the
amalgamating dish already described.
In witness whereof, I, the said George Henry Goodman, have
hereunto set my hand and seal, this Ninth day of February,
in the year of our Lord One thousand eight hundred and seventy-
two.
Witness,
GEORGE HENRY GOODMAN. (L.S.)
