"
My improved machinery or apparatus for breaking, grinding or pulverizing
stones or other materials has for its characteristic feature levers jointed upon pins
or axes which are fixed to a sleeve having cheeks or washers; this sleeve is itself
fixed to a metal shaft to which rotary motion is imparted; the levers are fitted' at
their ends with movable rollers of steel or other hard metal; these rollers by
reason of their mobility, the manner in which they are fixed and the rotation of the
sleeve are drawn into a circular movement against the inside of a surrounding
case; they turn upon their axes and crush the material which is thrown by the
levers against the case.
II_
7. An apparatus embodying my improvements is composed of the case. above
mentioned which is secured to a suitable frame by bolts; its ends are formed to
receive, bearings for a steel shaft carrying the sleeve on which the jointed levers
are fixed by pins or bolts; the outer ends of these levers carry the rollers which
are free to rotate on their axes.

The material to be operated upon is introduced into the case at the sides or top
and is thrown by the rotating levers against the inside of the case, it is met by the
rollers which crush and reduce it to the degree of fineness which is determined by
the arrangement of the outlet for the reduced material; there may be an outlet at
one or both sides of the apparatus; or if the material is required to be reduced to
an impalpable state the outlet should be at the upper part of the casing.

ALMONDS, BARKS, PHARMACEUTIC PRODUCTIONS AND OTHER MATERIALS"
My improved machinery or apparatus for breaking, grinding or pulverizing
stones or other materials has for its characteristic feature levers jointed upon pins
or axes which are fixed to a sleeve having cheeks or washers; this sleeve is itself
fixed to a metal shaft to which rotary motion is imparted; the levers are fitted at
their ends with movable rollers of steel or other hard metal; these rollers by
reason of their mobility, the manner in which they are fixed and the rotation of
the sleeve are drawn into a circular movement against the inside of a surrounding
case; they turn upon their axes and crush the material which is thrown by the
levers against the case.
The annexed drawings represent a machine or apparatus constructed in
accordance with my invention. Figure 1 is a transverse section and Figure 2 a
longitudinal section. The apparatus is composed of the metal case a which is
secured to a suitable frame b b by bolts; its ends are formed to receive bearings cc
for a steel shaft d carrying the sleeve e on which the jointed levers fff are fixed
by pins or bolts; the outer ends of these levers carry the rollers g g which are free
to rotate on their axes h.
The material to be operated upon is introduced into the case at the sides or top
and is thrown by the rotating levers against the inside of the case; it is met by
the rollers which crush and reduce it to the degree of fineness which is determined
by the outlet for the reduced material; there may be an outlet at one or both sides
of the apparatus; or if the material is required to be reduced to an impalpable
state the outlet should be at the upper part of the casing.
Having now described the nature of my said invention and in what manner the
same is to be performed I declare that I claim :-
Constructing machinery or apparatus for breaking, grinding or pulverizing
stones, ores, cements and other materials, with jointed levers carrying movable
rollers and combined with other parts substantially as hereinbefore described and
represented in the annexed drawings.
