PROVISIONAL SPECIFICATION.
Improved Apparatus or Machinery for Crushing, Grinding, and
Washing Metal Ores, Metal Dross and Ashes, Shop Sweepings,
Gold Quartz, and other Mineral Substances Requiring Separation,
also applicable as a Mortar Mill, and for Crushing and Grinding
Bones, Slag, and other suitable materials.
I, BENJAMIN MILLER of 3 Alexander Street, Park Lane, Leeds, Metal Refiner
and Smelter, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide improved apparatus or machinery for
crushing grinding, and washing, at one process by the "wet system," with self
delivery motion, metal ores metal dross and ashes, shop sweepings gold quartz, and
other mineral substances requiring separation; the said improved apparatus or
machinery being also applicable as a mortar mill, and for crushing and grinding
bones, slag, and other suitable substances.
In carrying out my invention I employ a fixed pan which consists of a channel or
chamber into which the material is placed. Travelling within the said channel or
chamber are two or more rollers or heavy runners which are secured upon shafts
pivotted or bolted to brackets so as to allow of the said rollers or heavy runners
"giving" when meeting with a sudden and unusually hard resistance in the
material.
The said brackets are carried upon or fixed to a vertical shaft working within a
bush at its lower end, and supported at or towards its top end by suitable means,
and at an intermediate position, having a spur wheel gearing with a pinion carried
upon a stud fixed to another bracket or arm. The said pinion also gears with
another pinion upon a shaft passing through the said bracket or arm having a series
of blades arranged so as to form a scraper to travel within the said channel or
chamber of the fixed pan. There may be one or more of such scrapers, and if
preferred, constructed like a screw or spiral, or any other suitable shape. The
vertical shaft aforesaid receives its motion from pulleys upon a driving shaft
journaled or fixed in bearings upon the frame of the mill, and by means of the
gearing the motion of the rollers or heavy runners and scrapers is speeded in the
required manner.
Instead of using spur wheels as before mentioned I may use bevel ones.

COMPLETE SPECIFICATION.
Improved Apparatus or Machinery for Orushing, Grinding, and
Washing Metal Ores, Metal Dross and Ashes, Shop Sweepings,
Gold Quartz, and other Mineral Substances Requiring Separation,
also applicable as a Mortar Mill, and for Crushing and Grinding
Bones, Slag, and other suitable materials.
I, BENJAMIN MILLER, of 3 Alexander Street, Park Lane, Leeds, Metal Refiner
and Smelter, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The object of my invention is to provide improved apparatus or machinery for

page_text: crushing, grinding, and washing, at one process by the "wet system" with self-
delivery motion, metal ores, metal dross and ashes, shop sweepings, gold quartz, and
other mineral substances requiring separation; the said improved apparatus or
machinery being also applicable as a mortar mill, and for crushing and grinding
bones, slag, and other suitable substances.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a side elevation of my improved apparatus or machinery.
Fig. 2, is a plan of my improved apparatus or machinery as shown in Fig. 1.
Fig. 3, is a plan of modification of my improved apparatus or machinery.
In carrying out my invention I employ a fixed pan which consists of a channel,
chamber, or circular trough A, into which the material is placed. Travelling
within the said channel, chamber, or trough are two or more rollers. or heavy
runners B, which are secured or fast upon shafts C, pivotted or bolted to brackets D,
so as to allow of the said rollers or heavy runners "giving," when meeting with a
sudden and unusually hard resistance in the material.
The said brackets D are carried upon or fixed to a vertical shaft E working
within a bush F at its lower end, and supported at or towards its top end, by a
crosshead or beam G, and at an intermediate position. having a fixed spur
wheel H gearing with a pinion J carried upon a stud L fixed to another bracket
or arm M.
The said pinion J also gears with another pinion N upon a shaft O passing
through the said bracket or arm M and having a series of blades P arranged so
as to form a scraper or stirrer to travel within the said channel, chamber, or trough
of the fixed pan A. There may be one or more of such scrapers or stirrers, and,
if preferred, constructed like a screw or spiral, or any other suitable shape. The
vertical shaft E aforesaid receives its motion from pulleys R upon a driving shaft S
(having fly-wheel S¹) journaled or fixed in bearings I upon the frame U of the
mill, and by means of the gearing the motion of the rollers or heavy runners and
scrapers is speeded in the required manner.
Instead of using spur wheels as before mentioned I may use bevel ones. V is a
bevel wheel upon shaft S gearing with wheel W upon the vertical shaft E, and by
means of which the vertical shaft E receives its motion.
For washing purposes, water is run into the channel, chamber, or circular
trough A, by means of pipe, and an opening R¹ is fitted with a tap for running off
the water when required.
A pipe R', having a canvas bag attached is also provided for catching what are
known as "tailings" or small particles of metal which are washed out of the pan A
by the over-flow water.
Further, a delivery arrangement is provided consisting in a pivotted plate R*
worked by handle R against the outlet R in the pan A by which means the said
outlet can be closed or opened as required.
Fig. 3.
In this modification the stirrers consist of barrels or cylinders X fitted with
prongs Y.
The rollers or heavy runners B are loose upon the shafts C and free to revolve
thereon. The barrels or cylinders X are supported by arms Z and Z' (with
brasses) and secured to the shafts C in the manner shown. Upon one end of the
said barrels are fixed chain-wheels Z over which are chains Z passing to similar
chain-wheels upon the shafts C, and keyed to or fastened to the rollers or heavy
runners B.
On the revolving of the rolls or heavy runners B motion is imparted to the stirrers
by means of the chain mechanism. Z₁ is a scraper connected with the shaft E for
bringing the material into the path of the rolls or heavy runners.
This arrange-
ment of the stirrers may be used either separately or in combination with the
arrangement of stirrers shown and described in Figs. 1 and 2.

page_text: My said improved apparatus or machinery (minus the rolls or heavy runners) is
also applicable for diamond washing.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
1. In apparatus or machinery for the purposes set-forth, the combination of a
pan consisting of a channel, chamber, or circular trough, with two or more rollers
or heavy runners, working therein, in the manner and for the purposes set-forth.
"
2. In apparatus or machinery for the purposes set-forth, the pivotting of the
rollers or heavy runners (working within the pan) whereby they are free to "give"
when meeting with a sudden and unusually hard resistance in the material, substau-
tially as shown and described.
3. In apparatus or machinery for the purposes set-forth, the combination with a
pan having two or more rollers or heavy runners working therein, of two or more
stirrers or scrapers also working within the said pan, and consisting of a series of
blades P upon a shaft O driven by suitable gearing from a vertical shaft, substan-
tially as shown and described with reference to Figs. 1 and 2 of the drawings
annexed.
4. In apparatus or machinery for the purposes set-forth, the combination with a
pan having two or more rollers or heavy runners working therein, of two or more
stirrers consisting of prongs Y upon barrels or cylinders X driven by chains Z³
and chain-wheels Z' from the rollers or heavy runners B, substantially as shown
and described with reference to Fig. 3 of the drawings annexed.
