To all whom it may concern:

Be it known that I, SIMON LAKE, a citizen of the United States, at present residing at 23 Friedrich WVilhelmstrasse, Berlin, Germany, have invented a certain new and useful Improvement in Drills, ofwhich the following is a full, clear, and exact description.

This invention relates to an improvement in drills particularly adapted for use in prospecting purposes in water beds where it is necessary to penetrate the over burden or rocky bottoms of the bed of the water, but which may be used with equal facility in dry drilling on land for the same purpose.

The object of the invention is to provide a drill especially adapted for rapidly cutting through the over burden, or through rock itself, in quartz mining and for lifting the samples of material and delivering them to the surface where the nature of the solids may be tested by any of the well known processes.

A further object is to provide a device in which the point of the drill is given a revolve ing movement together, and simultaneously with a percussive movement, and in utilizing the same medium employed for revolving the cutting point to lift the gold or other metals together with the particles severed from the bed and delivering them upon the surface; means being provided for accelerating the upflow of water as well as means for furnishing a percussive movement to the drill and also additional means for supplying a medium under pressure to revolve the point and lift and deliver the gold and other materials to and upon the surface.

The invention comprises means for accomplishing the stated objects and others, all as hereinafter more particularly set forth and finally claimed.

In the accompanying drawings, illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1, is an elevation showing diagrammatically the arrangement of my improvement. Fig. 2, is a detail elevation of the upper end of the tubes having the operating cylinder in position and which is employed for imparting a percussive movement to the drill. Fig. 2;. a detail sectional elevation of the lower ends of the tubes. Fig. 4, is a similar view of the upper ends thereof. Fig. 5, is a detail view illustrating the operation of the slide valve for controlling the supply of the operating influence to the piston cylinder. Fig.

6, is a detail section on the line 66 of Fig. 3. Fig. 7, is a similar view on the line 77 of Fig. I 3. Fig. 8, is an end view of the cutting head. Fig. 9, is a detail section drawn on the line 99 of Fig. 3. Fig. 10, is a'similarview on the line 1010 of Fig. 3. Fig. 11, is a sectional perspective view of the sleeve employed for supporting the turbine. Fig. 12, is a similar view of the turbine. Fig. 13, is a similar view of the cutter head. Fig. 14, shows detail views in perspective of one of the movable cutting points. In the drawings A, designates a tube which terminates at its upper end in a head A, from which project vertically extending arms A connected by links A to the beam of acrane B, carried by a surface vessel B, and by which the tube and parts carried thereby are supported and suspended in a vertical position.

Operating through the tube A, and through a stuffing box A*, in the head, is a tube C, of somewhat smaller diameter than' the tube A, and extending the full length thereof and which provides an annular space D, extending throughout the length of the tubes. Connected to the upper end of the tube is an elbow' pipe C, towhich is connected a flexible pipe D, whose opposite end is connected to a suction pump D located upon the surface vessel and operated in any suitable manner. To the elbow is also connected a piston rod E, carried by a piston head E,

a vertical reciprocating movement to the tube and the cutter carried thereby, as will be explained later on.

The cylinder is provided with a steam chest E having an oscillating valve E, controlling the inlet and exhaust ports to and from the cylinder, the valve being operated by a valve rod E carried by the elbow C, .ad extending through a stul'ling box E", formed upon the steam chest.

The valve rod is provided with a double faced cam head E, upon its upper end, which alternately engages beveled projections e, and 6, extending from the valve. The operation of the valve will be best understood from the general description of the operation of the device.

A steam pipe K, is connected to the steam chest for supplying steam thereto and exfits the interior of the tube A, and extends nearly to the lower end thereof, the sections being connected by webs F formed integral with the sections. The section F, is somewhat shorter than the outer section F is increased in thickness at its lower end, and

' has an internal annular groove F in which H ofthe cutter end is connected to a force is revolubly held the upper flanged end of a turbine wheel or sleeve G, having angularly arranged blades G, at itsupper end and an externally threaded flange G at its lower end. Screwed to the flange G is a cutter head H, having diametrically arran ed recesses H, in each of which is pivotally held a tapering or wedge shaped cutter H all of which cutters are designed to swing. outwardly upon the downward movement of the cutter head to cut or bore a larger hole than and thus form a clearance space for the tube A. The lower faces of the cutter head between the recesses are beveled in opposite direction, as shown at H to provide a 'plu-' rality of cutting edges and the flange of the turbine G, is provided with a series of openings G which re 'ster with openings H and ead and the pivoted cutter points respectively, which permit of the escape of the water after acting upon the turme. To the head A, of the outer tube A, is connected'a flexible pipe I, whose opposite um I, also located upon the surfacevesse an operated in any suitable manner and by which water is forced down under pressure through the space D between the tubes to engage the turbine.

The cutter is formed at its upper end with I a spider frame J, supporting a short vertically projecting spindle J, upon which is mounted a propeller J ,-which acts with the cutter and accelerates the u flow of the water and material cut from t e water bed.

Having described the general construction of my device, the advantages and operation thereof will be best understood from the 'fol-' lowing description of the operation. Assuming the (piston is in the upper end of the cylinderan the tube C, and cutter or drill point proper, likewise elevated. Steam is admitted 1nto the steam chest from which it escapes through the upper inlet port a,

and acting upon the piston will drive it downwardly to the lower end of the cylinder and ,through the medium of the tube will force the cutters into contact with the surface beexpanded steam from the upper surface of the piston previously to the inlet of steam to the lower part of the cylinder which, acting upon the piston, will elevate the same and likewise the tube C, and the cutter, thus providing a reciprocating movement to. the tube and a percussive-action to cutter. Simultaneously with this operation the force and suction pumps are set in motion, and the former, which may be stated, is connected with a suitable supply, forces water down throu h the annular space or passage D, and forcib y projects it against the blades of the turbine, imparting a revolving movement thereto and likewise to the cutter, and after the water has acted upon the turbine it passes through the openings G H and H and is drawn up through the tube C, by the suction pump together with the particles cut from the surface operated upon, and delivered into any suitable receptacle provided therefor. The propeller J may be employed for agitating and accelerating the upflow of water and material, through the'pi e C. The ro peller as shown is operated fiy and simu ta-. neously with the movement of the cutter.

It will thus be seen, I provide an exceedingly simple and highly efficient device for accom lishing the pur ose stated, and it may be ad ed that suitable plants may be em- 4 ployed and used in connection'with the drill for separating the materials and testing the nature of the solids on board the same vessel Farrying the drill and operating means there- What I claim is:
