IMPROVEMENTS IN THE CONSTRUCTION OF MILLS FOR GRINDING
Year: 1884

page_text: I ALBERT FERDINAND LINK of 6 Union Court Chambers Union Court in the
City of London Merchant do hereby declare the nature of my Invention for
IMPROVEMENTS IN THE CONSTRUCTION OF MILLS FOR GRINDING, a communication
to me from abroad by Josef Karasek of Elbe, Kosteletz, Austria to be as
follows:-
The object of this invention is to provide an improved form of mill for grinding.
In carrying out my invention I arrange two cylindrical stones, the axles of
which are parallel or nearly so. The distance between the stones is regulated by
band wheels and screws which move the plummer blocks or bearings of one of the
stones whereby the grinding can be made either fine or coarse as desired. The axles
may be placed in a horizontal or vertical position and it will be sufficient for
the purpose to describe the horizontal arrangement in this Specification.
Above the stones I place a hopper in which the articles to be ground are placed
and through the lower part of which they fall to the stones. The descent of the
material from the hopper is regulated by a slide; upon which slide are placed two
slotted bars to which two pinions are fitted, and which are moved by a hand wheel-
A cylinder of small diameter is also fitted at the lower part of the hopper, which
distributes the material to be ground in an even and regular manner to the stones.
The whole of the apparatus mounted on a suitable frame with driving pulleys
and belts or other gear for actuating the several parts by hand or other power.
A wooden frame being sometimes used for crushing or grinding such materials as
require but little power and an iron frame being preferred for grinding corn or
barder materials.
Arrangements are made for readily shifting changing or renewing the cylindrical
stones by unscrewing the upper bearings of the plummer blocks and if necessary
altering their position.

I, ALBERT FERDINAND LINK, late of 6 but now of 8 Union Court Chambers,
Union Court, in the City of London, Merchant, do hereby declare the nature of my
said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF MILLS FOR GRINDING
a communication from abroad by Josef Karasek, of Elbe, Kosteletz, Austria, 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 this invention is to provide an improved form of mill for grinding.
In carrying out my invention I vary the construction according to the material
intended to be ground. Those mills which are intended for agricultural use, are
fitted to a wooden frame and driven by hand power or driving bands. But those
which are intended to grind corn are fitted to an iron frame and driven by belting.
In describing the first class of mill the second will be understood therefrom.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings.
I arrange and fit two cylindrical or other stones a b (shewn by dotted lines) the
axles ab of which are parallel, or nearly so. The distance between the stones is
regulated by hand wheels f screws e and springs g which regulate the position of
the plummer blocks or bearings c of one of the stones to or from the other stone in
the guides dd, whereby the grinding can be made either fine or coarse, as desired.
The axle b¹ is fitted to fixed blocks.
Above the stones I place a hopper h into which the articles to be ground are
placed, and through the lower part of which they fall to the stones. The descent
of the material from the hopper is regulated by a slide; upon which slide are
placed two slotted bars to which two pinions are fitted, at i which are regulated by
a hand wheel k. A cylinder of small diameter is also fitted at the lower part of
the hopper, on the axle of the wheel Z, which distributes the material to be ground
in an even and regular manner to the stones a and b.
The whole of the apparatus is mounted on a suitable frame d.
The driving pulley m, mounted on the axle m¹ may be driven by any convenient
motive power.
This pulley actuates, or this and other pullies on the same shaft,
actuate the pullies fitted to the stones a and b, driving them in opposite directions,
as shewn by the arrows. The ground material falls from the stones into the
receptacle n, from whence it flows out by the spout o.
The stones may be cylindrical, conical, or of other suitable forms.
In case of undue pressure arising from the accidental insertion of stones &c.
between the stones, the springs g yield to such pressure and prevent breakage.
The whole of the working parts are made to take to pieces for purposes of
shifting, changing or renewing the same, and adjusting their positions.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1-In the construction of mills for the purposes aforesaid, the use of cylindrical,
conical, or other stones for grinding or triturating granular farm produce or for
grinding corn, substantially as described and shewn on the drawing.

page_text: 2-In the construction of mills for the purposes aforesaid, the use of the
regulating screws e, hand wheels f, and springs g, in combination with the sliding
bearings c and guides d, substantially as and for the purposes described and shewn
on the drawing.
3-The general combination and arrangement of the several and respective
parts, together forming my improvements in the construction of mills for grinding,
substantially as described and shewn on the drawing.
