3ERNHARD POST AND ROBERT GOEIRING, OF MEYERSVILLE, TEXAS
GRINDING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 624,086, dated May 2, 1899
Application filed Tune 18,1898. Serial No. 683,803. (No model.)To all whom t tay con-cern'.
Be it known that we, BERNHARD POST and
ROBERT GOEHRING, citizens of the United
States, residing at Meyersville, in the county
5 of De Witt and State of Texas, have invented
certain new and useful Improvements in
Grinding-Machines; and we do declare the fol-
lowing to be a full, clear, and exact descrip-
tion of the invention, such as will enable oth-
io ers skilled in the art to which it appertains to
make and use the same, reference being had
to the accompanying drawings, and to the let-
tersof reference marked thereon, which form
a part of this specification.
15 This invention relates to grinding - ma-
chines, and is particularly directed to im-
provements in the class of machines employed
for crushing corn and the like, the object of
the invention being to combine in a simply-
20 constructed and efficient machine mechan-
ism for cutting or dividing the corn and mech-
anism for further reducing it by a crushing
or grinding operation. The invention also
has for its object the provision of means
25 whereby the said mechanisms may be easily
and quickly adjusted to suit varying condi-
tions.
The invention consists of the construction
and relative arrangement of the several parts
30 of the machine, all of which will be found
fully and clearly disclosed in the following de-
tailed description, which is to be read in con-
nection with the accompanying drawings, in
which-
35 Figure 1 is a side elevation of our improved
grinding-machine. Fig. 2 is a top plan view,
the casing being removed; and Fig. 3 is a ver-
tical sectional view taken on line 3 3 of Fig.
2 and showing in full and dotted lines ad-
40 justed positions of certain of the parts.
Referring to the said drawings by letter, A
denotes the frame of the machine, the same
consisting of side bars a a, end bars a' a2, sup-
porting legs or standards a2 ai, and lower side
45 bars a4 a4. On the side bars a a are boxes b b,
in which is journaled the operating-shaft c,
carrying a drive-pulley c' and a fly-wheel c2.
Rigidly mounted on the shaft between its
bearings is a revolving cutter D, consisting of
5o cylindrical sections d d, between which are
knives d' d', triangular in form and so dis-
posed as to be brought successively into op-eration, the points to this end being arranged
in spiral alinement.
E denotes a hopper - plate secured at its 55
outer end to a casing-section F, slidably sup-
ported on the side bars a a, said plate extend-
ing downwardly from the section at an angle
to afford a base e, and thence upwardly at an
angle and in the path of the knives d' c', and 6o
finally rearwardly, as at e' In the hopper-
plate are slots el e2, which extend through the
base and through the inclined side and af-
ford openings through which the knives are
successively brought and also outlets for the 65
cut corn. To regulate the cut of the knives,
the hopper-plate is capable of adjustment to
or from the cutter, the means employed con-
sisting of a lever g, pivoted on the end bar a'
and having connection through a rod g',passed 70
through a slot in said bar, with the casing-sec-
tion F, by which arrangement movement of
the lever is communicated to the casing-sec-
tion and hopper-plate, certain adjusted posi-
tions of these parts being shown in full and dot- 75
ted lines in Fig. 3 To maintain such adjust-
ment, there is provided in the path of the
outer end of the lever a rack-bar g2, the teeth
of which are engaged by a projection g3 on
the lever, disengagement being accomplished 8o
by raising the latter, as will be understood.
II denotes a casing which is removably
placed on the top of the frame to afford a
housing for the cutter, and in the upper side
of the casing is a hopper-shaped opening h, 85
the walls of which form a continuation of the
hopper-plate E.
Below the cutter is a grinding or crushing
roll I. This roll is rigidly mounted on a
shaft 3, journaled in boxes b' b' on the lower 90
side bars a4 a4, and motion is given to the
roll through a gear-wheel 3', carried by the
shaft}?, which meshes with a gear-wheel c3on
the shaft c The roll is provided on its pe-
riphery with spirally-arranged corrugations 95
or plates z 2, which are brought to an edge
and operate to further reduce the corn as it
comes from the cutter.
K is a plate which cooperates with the roll
in the grinding or crushing operation, the ioo
plate at that portion k adjacent to the roll
being semicircular in cross-section and serv-
ing to bring the corn into close contact with
the latter, to be acted upon by the grinding
