June 23.] THE NEW ZEALAND GAZETTE. 1605

Claims.—(1.) A deep-boring apparatus provided with water-jet supplied through the drill-rod, characterized by the fact that a valve, normally kept open by suitable means, closes when the water has reached a certain maximum speed, and again opens when the pressure produced by the blow of the water for driving the tool against the sole has created a rarefaction, whereupon a spring withdraws the piston, substantially as described. (2.) A constructional form of the arrangement claimed in claim 1 in which the admission-valve l is arranged within the piston (Fig. 1), while the water flows through the hollow piston-rod f to the sole, substantially as described and shown in the drawings. (3.) A constructional form of the arrangement claimed in claim 1, in which the piston d is solid and the valve i annular, so that the water-current admitted through the open valve passes between the cylinder c and a jacket or outer casing n to the sole, while when the valve is closed the suddenly arrested water is caused to pass through the annular valve i so as to strike on to the piston d (Fig. 2), substantially as described and shown in the drawings. (4.) A constructional form of the arrangement claimed in claim 1, in which the valve is made in the form of an elastic plate o (Fig. 3), or a sleeve p (Fig. 4), or an elastic ring, which in its unloaded condition is lightly separated from its seat, and is only pressed on to this latter by the force of the water-current, substantially as described with reference to the drawings. (5.) A constructional form of the arrangement claimed in claim 1, in which the exhaust pressure-water is conducted away by a pipe s (Fig. 5) arranged laterally above the boring-tool, said pipe being adapted to be closed by a valve i (Fig. 5), substantially as described and shown in the drawings, and for the purposes set forth. (6.) A constructional form of the arrangement claimed in claim 1, in which an elastic element is arranged between the striking water-column in the chamber c (Fig. 6) containing the valve and the rod d (Fig. 6) of the bearing-tool, substantially as described and shown in the drawings, and for the purposes set forth.

(3.) For the purpose indicated, a cylinder having tangential holes in its circumferential periphery, as set forth. (4.) In apparatus for the purpose described, a feed-hopper having an opening for the passage of seed, and a slide for adjusting the size of the said opening, as set forth. (5.) In apparatus for the purpose described, cylinders having holes in their circumferential peripheries and a shaft upon which the cylinders are mounted and the interior of which the said shaft fits, as set forth.
