page_text: the said Invention for "IMPROVEMENTS IN AMALGAMATING MACHINES, a com-
munication to us from abroad by Samuel Francis Clouser, of New York,
in the State of New York, of the United States of America," to be as
follows:-
This Invention relates to that class of amalgamating machines which
have the pan heated by steam or other means, and are fitted with
rotating arms carrying mullers or grinders, and consists :—
In providing the muller or grinder, which consists of a crossed iron
frame, with cast-iron shoes formed cone shaped and ploughshare shaped.
The said shoes are so attached to the muller or grinder as to be laterally
adjustable, and are caused to cover every part of the bottom of the pan
during the revolution of the said muller or grinder, thus effectually
ensuring amalgamation.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said John
Henry Wiggins and Samuel Leonard Tilley Carvell in the Great

from time to time and at all times thereafter during the term therein

page_text: 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 AMALGA-
MATING MACHINES," a communication to them from abroad by Samuel
Francis Clouser, of New York, in the State of New York, of the United
States of America upon the condition (amongst others) that we, the said
John Henry Wiggins and Samuel Leonard Tilley Carvell, our executors
or administrators, by an instrument in writing under our, or their, or
one of our or 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 on or before the Eighth day of December 1875.
NOW KNOW YE, that we, the said John Henry Wiggins and Samuel
Leonard Tilley Carvell, do hereby declare the nature of our said Inven-
tion, 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 accompanying Sheet of Drawings, and to the figures
and letters marked thereon, that is to say :-
This Invention relates to that class of amalgamating machines which
have the pan heated by steam or other means, and are fitted with
rotating arms carrying mullers or grinders, and consists:-
In providing the muller or grinder, which consists of a crossed iron
frame, with cast-iron shoes formed cone shaped and ploughshare shaped.
The said shoes are so attached to the mullers or grinders as to be laterally
adjustable, and are caused to cover every part of the bottom of the pan
during the revolution of the said muller or grinder, thus effectually
ensuring amalgamation.
Fig. 1 is a sectional elevation of our improved amalgamating machine;
and Fig. 2, a plan view of the under side of the muller or grinder.
a is the pan which contains the precious metals or other material to
be operated upon, provided with the steam jacket 6 for heating the same;
c, driving shaft giving motion to the upright shaft d through the bevel
wheels e. The upright shaft d carries the muller or grinder by means
of the yoke or bow f; g, screw for adjusting the height of the muller

page_text: or grinder; h, shoes attached to the cross arms i by means of the dove-
tailed grooves j, thus allowing of adjustment of the said shoes laterally.
The said shoes are of cast iron, and are made cone shaped and plough.
share shaped, as shown, so that when the muller or grinder revolves the
substance or material being amalgamated is driven in a current towards
the centre of the pan; 7 are openings through which the treated material
can be run off.
Having now particularized the nature of our said Invention, so that
others will be enabled to carry out the same, we claim, the improve-
ments in amalgamating machines herein described and illustrated.
In witness whereof, I, the said John Henry Wiggins, have here-
unto set my hand and seal, the Twenty-sixth day of November,
in the year of our Lord One thousand eight hundred and seventy-
five
In the presence of
