roller I, however, instead of being driven by
a belt, may be driven by a pinion in the place
of the driver a, the pinion engaging cogs on
the wheel S, as indicated in Fig. 2.
b is a pitman connected to the outer face of
the wheel S at one end, and at the other to a
horizontal lever, c, extending across the ma-
chine, and centrally pivoted to the frame A.
d is a vertical lever turning on spindles ex-
tending from its central part, and having suit-
able bearings. e is a horizontal lever pivoted
at one end to the frame A at a point above
the spindle or supporting-bar of the lever d,
and laterally from the said lever, as repre-
sented in Fig. 7. The upper end of the lever
d passes freely through the lever e; and to
prevent the lever e from tending to twist the
lever d when the lever e is moved back and
forth, I make the opening in the latter broader
at one end than at the other, and make a V-
shaped projection in the narrow end of the
opening, and a vertical groove, also V-shaped,
in that side of the lever d which is next to
the said projection, as is clearly shownin Fig.
8. f is a connecting- arm connecting the
lower end of the lever d to the bar M, the said
arm being jointed or pivoted to the parts con-
nected by it. g is an angular or T-shaped le-
ver or double bell-crank pivoted to a cross-
bar, t, and having pins or studs i i extending
freely into openings or holes in the slide D D.
j j' are connecting-arms connecting the lever
c to the levers e and g, respectively.
The wheel S should be rotated in the dircc-
tion indicated by the arrow, and the earth fed
into the chute B. The inclination of this
chute is such that the earth will find its way
to the teeth arranged in the chute. The ro-
tary movement of the driver S imparts a lat-
erally-sliding movement to the slides D D,
which move reversely or in opposite directions,
owing to the action of the lever g, which re.
ceives a vibrating motion from the joint action
of the pitman b, lever c, and connecting-arm
j'. The earth is thus broken up or pulverized
sufficiently to pass between the teeth in the
chute and to fall upon the shelf G. The earth
in falling upon the shelf G is subject to the
action of the roller I and the teeth H H, and
its larger lumps are reduced. The reverse
movement of the slides D D not only breaks
up the earth, but thoroughly mixes it, so that
by the time it falls into the sieve L it is well
ground and mixed. It is also still further
mixed in the sieve, for the latter, owing to its
connection with the lever d, is moved back
and forth, the said lever receiving its motion
through the pitman b, lever c, connecting-arm
j, and lever e. The earth which passes through
the sieve falls upon the endless apron N, and
is by it carried to and dumped into the re-
ceiver P. From the receiver P the earth is
raised to the chute 11 by means of the eleva-
tor-buckets, and from this chute it may be
passed to any suitable place for use.
This machine will be found to be especially
useful in connection with brick-machines. Itfrequently happens that clay and earth suit
able for making brick differ sufficiently in
different places to impair the operation of a
machine in one place, or while working on
material from one locality, when the same
machine, working at a different place, or on
material from a different place, would give en-
tire satisfaction. In such cases the machine
which I have now described will prepare the
clay or earth for a brick-machine in such a
manner as to render the action of the latter
machine uniformly satisfactory, although the
character of the material operated upon may
vary.
Letters Patent of the United States of
America No. 206,247 were issued to L. B.
Kennedy the 23d day of July, A. D. 1878, for
improvements in brick-machines, and in using
that machine in connection with the one here-
in particularly described the earth is deposited
from the chute R1 upon the revolving table in
the former machine, which operates in the
manner described in the said Letters Patent,
and with the advantageous results already set
forth.
Having thus described my invention, what.
I claim as new, and desire to secure by Let-
ters Patent, is-
1. The combination, substantially as de-
scribed, in a machine for grinding and mixing
earth, of the hopper or downwardly-inclined
.feedway or chute B, having therein the up-
wardly-projecting teeth C C, and the reversely
and laterally movable slides D D, provided on
their lower faces with the teeth E L, extend-
ing downward between the teeth C 0, for the
purposes set forth.
2. The combination, in a machine for grind-
iug and mixing earth, of the feedway or chute
B, the curved shelf 0, arranged at the lower
end of the said feedway, the corrugated roller
I, arranged over the said shelf, the fixed teeth
C and H, and the laterally-movable teeth E
E, for the purposes set forth.
3. The combination, substantially as de-
scribed, in a machine for grinding and mixing
earth, of the chute B, the fixed teeth C C, the
movable teeth E E, and the sliding sieve L,
all arranged substantially as specified with
relation to each other, for the purposes set
forth.
4. The combination, substantially as de-
scribed, in a machine for grinding and mixing
earth, of the chute B, the fixed teeth C C, the
movable teeth E 1, the sliding sieve L, and
the endless apron N, all arranged substantially
as specified with relation to each other, for the
purposes set forth.
5. The combination, substantially as de-
scribed, in a machine for grinding and mixing
earth, of the chute B, the fixed teeth O C, the
movable teeth E E, the sliding sieve L, the
endless apron N, the receiver P, and the ele-
vator Q, all arranged substantially as de-
scribed with relation to each other, for the pur-
poses set forth.
6. The combination, in a machine for grind-
