Refer-ring to the cirawing,,it will'bejnoted jthet I my invention, inv its illustratiueiform, .is incorp'ojg vratedei'n ia,drilling mechanism of thehamnie'r actuated type; the iforwardmor'tion ot which is v i 7 indicated at The invention may; however,

a chuck housing 6 held in assembled relation with the other parts of the motor by usualside rods 1, coiledsprings 8 and nuts 9.. Within the chuck housing 5,.is rotatably mounted a chuck sleeve l connected, as by clutch teeth at its forward end, to a'driver member [2 having usual lugs which are enagageable' with lugs l4 formed on the shank o fthe drilling tool 4 for driving the latter. The rear portion of the drillingtool is slidably supported in a usual manner within a chuck bushing I5 suitably securedto'the chuck sleeve I0, and the r'earend of the drilling tool projects beyond the chuck bushing torec'eive blows delivered thereto by a striking bar Hi of a hammer piston. Formed on the striking barpassage 22, and a conduit 23 extending. longitudinally through the striking bar l6 to aspace attherear end of the drilling'tooldeliversair under pressure from any suitablesource to the passage 2 2 which conductsrthe air to the bottom A suitable bit 54 is carried at thebottom of the drill rod. The drilling tool support or drill rod 4 and the bit 54 evidently cooperate or unite to form a drilling tool.
Supported by the drill rod at a point spaced from its forward end isthe improved hole cleansing device, generally designated '24. The hole cleansing device comprises a circular disk25 havinga diameter slightly lessthan that of the hole .sothat it will not wedge in the'hole during the drilling. of the latter and'yet large enough so that the clearance around its vperiphe ry,,will
V be sufiiciently small to prevent the; escape of substantial quantities of fluid from the bottom of the'hole past thedisk; The disk is looselysup ported by the drill rod in a manner to prevent it from moving longitudinally of the latter but at the same time to permit free rotative movement between the rod and the disk. In this case the support for the disk is provided at the junction of two rod sections 26 and 21 threadedly connected together, as at 28, and. includes a shoulder 29 formed ,on the'section 26 and a shoulder 30 ,formed on the upper end of the section 21, these shoulders having between them" an annular groove 3| for receiving the annular portion. of
the disk surrounding an opening 32 through which thefforward end of the rod section 26 extends. The groove 3l is of such width when the rod sections 26 and 21V are in full threaded engagement, as to provide a loose j fltforthe disk 25. A small clearance 33 is provided between the wall of the opening 32 in the disk and the. periphery of thejrod section 26 to permit relative transverse movement between the disk and drill rod; Formed in the disk'is apassage 314 communicatingatbne end with a port 35 opening through the upper surface of the .disk,
iandopening. at its other end into a passage 36 .extending through the disk. as shown in Fig. 2. A flexible conduit or tube 38 is connected in communication with theport 35 by a connecting of any suitable devices not shown. Threaded into the end of the passage 34 opening into the passage 36 is a nozzle 40 which extends upwardly a 'short distance into the passage 36 and discharges along the aXisxoi the latter. A flexible tube 42 is connected by a connecting element 43' to the passage 36 at the, upper side of the disk.
The crosssectional areaof the passage in the tube 42 is madelarge enough to enablethe ready discharge of the cuttings along with the air 'enterin the hole through the passage 22 and the air; delivered through the nozzle 40, but small enough to maintain a velocity of flow which will ensure the cuttings .being carried along in the flowing column of air. If other flow augmenting meansthan the nozzle 40 were used, e. g., a
vacuum producing arrangement connected to the discharge end of the'conduit 42, a modification in the flow area of this conduit might be if desired, a plate 46 maybe placed onthe surface, and be providedwith openings 41,48 and 49 through which the drillrod and the tubes 38 and 42, respectively, may extend. The openings48 and-49 are so located as to hold the tubes 38 and 42irom frictionalengagement'with the Walls of the hole,-andjthe'upperjedges ofv the holes are rounded at 51 and 52 to reduce wearing of the tubes.
As thepiston' of the hammer motoris' recipro cated tofdeliver impact 'blowsto the end of the drillingtool through the striking bar, l,5,;th e'motor is moved alongjthe feed cylinders 3' tobring. the
but as the hole deepens difficulty would;be. en-
countered in a hole of substantial size were'it not.
7 hole largely int'erruptsthe escape of fluid through "the bore of the hole; sothat anadequate discharge rate throughthe passage 42 may be se'-. r cured. As previously-noted, the cuttings are di-' rected to this passage, by the concave lower side 44 of the plate, and the nozzle discharging into the conduit 42 increasessubstantially the velocity of flow throughthe'latter, 'As previously note, additional turbulence oi the airwithin the space below the'partition'inember might be pro- ,vided for the purpose of maintaining the" rock dust and cuttingsin; suspension byproviding an auxiliary 'jet opening" downwardly through the member 25 from'the conduit 35. ]It will bebbserved that the'materiaicarried by the air flow- '7 ing through the conduit 42 to the surface is'not only more efiectually and positively discharged due to themuch higher velocityof thestr'eam of fluid flowing through this conduit;"but also the cuttings may be discharged at any desired P int. j f
