A GRINDING-MILL WITH TWOFOLD SIMULTANEOUS ROLLER-MOVEMENT
Year: 1884

page_text: I, MAX HEDICKE, of 3 Adelaide Place, London Bridge, London EC in the
county of Middlesex, Merchant, do hereby declare the nature of said Invention
for A GRINDING-MILL WITH TWOFOLD SIMULTANEOUS ROLLER-MOVEMENT to be as
follows:-
This invention relates to the construction of a Mill as represented in attached
Drawing, and has for its purpose not only to crush malt through the revolving
action of the rollers, but to triturate it by means of another linear movement of
the rollers, and by thus better preserving the husks, to be the cause of effecting a
better dissolution of the grist.
The linear movement of the rollers consists in an oscillation, preferably of one
roller in the pair, parallel to its long axis, and is preferably effected by an obliquely
ridged wheel, working between two small conical fixed rolls, and being fixed to the
roller. The periphery of this wheel represents in its one half a rising and in its
other half a falling spiral line..
While during one half of the rotation the rising part pushes the roller to the
right, the falling part pushes it during the other half equally to the left, the roller
thus sliding during each complete rotation once forward and once backward..
The novelty of the invention consists in the oscillating movement of the rollers
during rotation, and in the employment of the described ridged wheel for the
purpose of effecting such oscillation.

page_text: COMPLETE SPECIFICATION.
I, MAX HEDICKE, of 3 Adelaide Place, London Bridge, London E.C., in the
county of Middlesex, Merchant, do hereby declare the nature of my invention
for A GRINDING-MILL and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to the construction of a mill, and has for its purpose not
only to crush malt through the revolving action of the rollers, but to grind it also
by means of a linear movement of the same, and by thus better preserving the
husks, to be the cause of effecting a better dissolution of the grist.
In order that my invention may be more fully understood I hereto annex a sheet
of drawings illustrative thereof.
Figure 1. is an end-view of the mill.
Figure 2. is a longitudinal vertical section of the same.
Figure 3. is a front-view of the mill, showing that side where the roller lies, to
which a ridged wheel is fixed, which works between two conical rolls.
Figure 4. is a horizontal section of the mill. .
"
The linear movement of the rollers consists in an oscillation of one roller in the
pair, parallel to its long axis, and is effected by an obliquely ridged wheel b., fixed
to that roller, and working between two small conical fixed rolls a. a.-The.
periphery of this wheel represents in its one half a rising and in its other half a
falling spiral line. While during one half of the rotation the rising part pushes
the roller to the right, the falling part pushes during the other half equally to the
left, the roller-thus sliding during each complete rotation once forward and once.
backward.
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
"The oscillating movement of the roller during rotation through the employment
of an obliquely-ridged wheel in combination with fixed rolls, between which the
ridged wheel works, substantially as herein before described."
