removing the products of such drilling by the combined use
of the described drill and annular-valved bucket, adapted to
engage and disengage the drill-rod as and when required.
(2.) The method of drilling and removing rock and earth,
consisting in (a) breaking the contents of the bore by a drop-
drill, (b) raising the cutter just clear of the broken material,
(c) lowering an annular-valved bucket removably and tem-
porarily attached to the drill-rod into the broken material,
(d) lifting the bucket by mechanism which at the commence-
ment of raising releases the attachment and enables the
bucket and contents to be lifted along the rod to the surface
without withdrawal of the rod, substantially as described.
(3.) In combination, a jumping-drill such as described, with
actuating mechanism and an annular-valved bucket, com-
prised of an outer cylinder and an inner cylinder connected
together by a bridge-piece at the top and with valves at the
bottom, and adapted to be moved up and down upon the
jumping-rod, having cam clutches fitted to grip the rod when
necessary, substantially as described and for the purposes set
forth. (4.) In appliances for jump-drilling, the described
tool having three stud cutters constructed, arranged, and re-
movably attached thereto, as and for the purposes set forth.
(5.) In appliances for jump-drilling, an outer cylinder and an
inner cylinder connected together by a bridge-piece at the
top and with valves at the bottom, and forming an annular-
valved bucket with pivoted cam clutches having vertical
grooves in their faces, the upper parts of such clutches being
connected by flexible connections to a rope whereby the
bucket may be moved up and down upon a round boring-rod,
and which cam clutches grip such rod when the bucket is
being filled, substantially as described and for the purposes
set forth. (6.) In combination with the appliances for jump-
drilling, a cylinder having a collar-shaped cutter at the
bottom and springs attached to the inside, and having their
free ends extending inwards and upwards, adapted to lift
stones or boulders, substantially as described. (7.) In ap-
pliances for jump-drilling, a conically inclined cylinder, with
cam clutches oscillating to and from the centre, adapted to
find and engage the shank of the tool, two chains attached to
projections at the bottoms of the clutches and connecting
them with the lifting-rope, substantially as described and for
the purposes set forth.
