to cut a conical cavity with the sides there-
of at an angle less than 45 degrees to the
axis of rotation of the frame, and the sur-
faces of the drums being eccentric with rela-
5 tion to their axis of rotation.
15. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame, a
plurality of inclined rotating drums carried
by the frame, bearings for the drums, lubri-
10 eating passages for the bearings extending
longitudinally of the drums and communi-
cating at the bottoms of the drums, and
means for forcing oil down through the
passage in one drum and up through the
15 passage in another.
16. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame,
a plurality of inclined rotating drums car-
ried by the frame, bearings for the drums,
20 lubricating passages' for the bearings ex-
tending longitudinally of the drums and
communicating at the bottoms of the drums,
a reservoir of oil above the drums, and
means for circulating oil from the reservoir
25 down through the passage in one drum and
up through the passage in another drum and
into the reservoir.
i. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame, a
30 plurality of inclined rotating drums carried
by the frame, bearings for the drums, lubri-
cating passages for the bearings extending
longitudinally of the drums and communi-
cating at the bottoms of the drums, a reser-
35 voir of oil above the drums, and means op-
erated by the rotation of the frame for forc-
ing oil from the reservoir down through the
passage in one drum and up through the pas-
sage in another drum and into the reservoir.
40 18. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame, a
plurality of inclined rotating drums carried
by the frame, bearings for the drums, lubri-
cating passages for the bearings extending
45 longitudinally of the drums and communi-
cating at the bottoms of the drums, a reser-
voir of oil above the drums, a pump operated
by the rotation of one of the drums, and
connections from the passages in the drums
50 to the reservoir and pump whereby oil is,
pumped from the reservoir down through
the passage in one drum, then up through
the passage in another drum and then back
into the reservoir.
55 19. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame, a
plurality of inclined rotating drums carried
by the frame, bearings for the drums, lubri-
cating passages for the bearings extending
60 longitudinally of the drum and communi-
cating at the bottoms of the drums, a reser-
voir of oil above the drums, a pump op-
erated by the rotation of one of the drums,
and connections from the passages in the
65 drums to the reservoir and pump wherebyoil is pumped from the reservoir down
through the passage in one drunk, then up
through the passage in another drum and
then back into the reservoir, a check valve
being provided for preventing a reverse flow 70
of oil.
20. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame, a
plurality of inclined rotating drums carried
by the frame, bearings for the drums, lubri- 75
eating passages for the bearings extending
longitudinally of the drums and communi-
cating at the bottoms of the drums, a reser-
voir of oil above the drums, an outlet pipe
extending from a point adjacent the upper 80
part of the reservoir to the upper end of
one of said passages through a drum, means
for circulating oil down such last passage
and up through the passage through another
drum and into the reservoir again, and a 85
water pipe leading into the oil reservoir
from the upper portion thereof and extend-
ing to a point adjacent the bottom thereof.
21. In combination in boring apparatus, a
rotatable framework and a plurality of ro- 90
tatable drums carried by the framework, the
said drums being provided with a plurality
of circumferential rows of flat cutter bars,
the flat faces of the cutters on one drum
being at substantial right angles to the flat 95
faces of the cutter bars on another drum.
22. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame-
work, a plurality of rotatable conical drums
carried thereby and provided with cutting 100
means at their surfaces, the angle of inclina-
tion of the surfaces of the members to the
vertical at the sides thereof remote from the
center line of the framework being less than
the angle of inclination of such surfaces to 105
the horizontal, and a drilling member car-
ried by the frame in advance of the drums
and adapted to drill a hole of less diameter
than that cut by the drums, the said drums
being also inclined laterally in the same cir- 110
cumferential direction to secure a screw ef-
fect tending to force the drilling member
into the -round.
23. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame, a 115
plurality of rotatable conical drums carried
thereby, and a drilling member with a cut-
tinM point carried by the frame in advance
of the drums and adapted to drill a hole of a
diameter less than that cut by the upper 120
ends of the drums and greater than that cut
by the lower ends of the drums.
24. In combination in apparatus for drill-
ing holes in the ground, a rotatable frame, a
plurality of rotatable drums carried thereby, 125
and a drilling member with a cutting point
carried by the frame in advance of the drums
and adapted to drill a hole of a diameter
less than that cut by the upper ends of the
drums and greater than that cut by the 130
