Year: 1857

page_text: LETTERS PATENT to John Holley Swan, Engineer, 16, Royal Exchange
Square, Glasgow, in the County of Lanark, for the Invention of
"IMPROVED MACHINERY AND STEAM ENGINE FOR CRUSHING QUARTZ AND OTHER
HARD SUBSTANCES, AND FOR AMALGAMATING."
Sealed the 5th January 1858, and dated the 9th July 1857.
PROVISIONAL SPECIFICATION left by the said John Tolley Swan at the
Office of the Commissioners of Patents, with his Petition, on the 9th
July 1857.
I, JOHN HOLLEY SWAN, Engineer, 16, Royal Exchange Square, Glasgow,
in the County of Lanark, do hereby declare the nature of the said Invention
for "IMPROVED MACHINERY AND STEAM ENGINE FOR CRUSHING QUARTZ AND OTHER
HARD SUBSTANCES, AND FOR AMALGAMATING," to be as follows, and consists in
arranging and using two or more pairs of rollers acting in concert, and covered
with rods of steel, iron, or other suitable metal, so that the faces may be easily
renewed. The material to be crushed is received and partially crushed by the
upper rollers, and afterwards passes between and is further crushed by the
lower rollers, whence it passes by a pipe into the pan of the amalgamator,
which is made of the shape shown in the annexed Drawing A. To prevent
rapid wear I chill or barden the bottom. The outline of the
increased or diminished according to the size of rollers used.
pan may be

I use a boiler, having the peculiarly formed bottom shown in the annexed
Drawing, which form is particularly suitable for burning wood, as it gives
great length of fire bars. When coal is burned the bars may be shortened.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Holley Swan in the Great Seal Patent Office on the
9th January 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HOLLEY SWAN; Engineer, 16, Royal Exchange Square, Glasgow, in the County
of Lanark, send greeting.
WHEREAS ller most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of July, in the year of our Lord Ono
thousand eight hundred and fifty-soven, in the twenty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, tho
said John Holley Swan, ler special licenco that I, the said John Holloy Swan,
my executors, administrators, and assigns, or such others as I, the said John
Holley Swan, 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 "IMPROVED MACHINERY AND STEAM
ENGINE FOR CRUSHING QUARTZ AND OTHER HARD SUBSTANCES, AND FOR ANALGA-
MATING, upon the condition (amongst others) that I, the said John Holley
Swan, my executors or administrators, by an instrument 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 John Holley Swan, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the annexed Drawings, Fig. 1, Sheet 1,
showing an arrangement of two or more pairs of rollers A, A, A, A, acting in
concert for crushing, the clothing of these rollers being seperate rods or bars

page_text: of steel, iron, or other suitable metal, as at B, B, so that the faces may bo
easily renewed.
The material to be crushed is received by the upper set of rollers and
thereby crushed to a certain extent. Passing from them it is received and
further crushed by the rollers below, and passed from them to where it may
be required. As many sets of rollers may be used as the case demands.
The amalgamator I prefer to make of the form shown Fig. 2, Sheet 1, and
more especially with regard to the outline of the bottom of the pan on the
inside, and the water passages, c, c, c, c, c. This outline will be increased or
diminished according to the size of the rollers used. The bottom of the pan
is chilled or hardened.
The steam engine I also prefer to construct of the form shown Sheet 2,
more especially as regards the boiler, as being more suited for wood as fuel,
by giving an extra large fire space, as at D, D; and I place the fire bars
either within this space so for the engine to be used on its wheels, or I
place the fire bars on a framing of iron, or on a building, as may be most
suitable, placing the engine thereon.
In witness whereof, I, the said John Holley Swan, have hereunto set my
band and seal, this Fifth day of January, in the year of our Lord
1858.
JOHN HOLLEY SWAN. (L.S.)
