DRILLING arranar'trsj I To 'all whom fit maycofnt'em: v

Be it known that I, JAMES KAMMERDINB, a citizen 'of the United States of-America,

residing at Fullerton, county of Orange, State of California, have invented a certain -new 'and useful` Drilling Apparatus; and I do hereby declarethe following 'to be Ia ful-l,

clear, vand exact description of the invention,

suchy as will lenable others skilled itu the 'art to' which it appertains to make `and use the same.`

This invention relates to drilling 'a'.pf'para-` tus, vand it may be said'to consist inthe pro- Speciication ofLetters Patent. fPaten-ted Feb, 16, 1915, applic-anun mea annees, 191,4. semina. atasco.

on the line 3-3 of Fig. 1 and showing the cable operatively connected with the drilling mechanism; Fig. 4 is a broken enlarged sectional view of .the drilling apparatus,

showing the; :cable operatively4 disconnected .from..the1drilling mechanism; and Fig. 5

isacross-se'ctional,view taken onA lthe linel vision of the novel -and advantageous fea; j

tures and in *the novel and improved-construction, arrangement, and combination of parts and devices as will be apparentfrom the description and claims which "follow hereinafter.

One'obje'ct 'of the invention is VLto' providea novel and improved percussive drillingapparatus in which the stem vof the Adrill bit is hollow and passes through a stuilin'g box at the lower end of the casing; whereby the drilling operation may be 'expedited by the use 'of iiuid under pressure, and the drill bit may be of such size as to 4make a hole suiiiciently largery than the casing to permit of the casing being let down 'as the hole is deepened without the'necess'ity of bailinior l l i l sageway 20 which is in vcommunication with reaming'the hole.v

Another object of the inventioni's to prov vid'e 'a novel 'and improved means whereby the rope 'or cable may be easily and' quickly operatively connected?` with or .disconnected 'from ldrilling mechanism without raising the drilling mechanism from thelower part Y'of the casing` Further objects of the invention are to specified which is simple in construction,

. economical t'c manufacture, install; and

maintaineasy and convenient to' use, and effect-ive in action. Other objects and the advantages of the invention will heA app-arent from 'careful consideration ofthefollowing description .taken on the line2-2 of Fig. 1; Fig. 3 is an enlarged longitudinal sectional view takenprovide drilling apparatus of vthej nature'v erated bythe usual or Thecasingl'() is provided with a stufling box 11 ior the likeaft-'its lower lend vand it is provided with ashoulder 12 lat a suitable distance' above its .lower end. The shoulder '12 is `preferably provided by means of the lower :end -'of the fscction, 13' of the casing which section i'S of .smaller diameter mthan the' lower section 14 of the casing and is vconnected to the section 14 by means vof the I union 1,5.

The drilling mechanism preferably C011-, Y

sists ofthe bar 16 having' its lower end screwed into the upper end vof the 3ars 17,'

andy the stem 1'8 which passes sli'dably through the stuiiin'g' box 11 and, which has its upper enddetachably connected tothe lower end of the jars 17 and has detachably mounted on itsdowerend the bit 19 which latter ispreferably greater in widthl than l are, the sections 13 or 14, or the union 15',

in diameter. ,The stem has thereon a shoulder .-23 andqitis provided with a' pasthe. passageway 21;and thebranch passage; ways 22 in the bitf19. A T'tting 24is pro-4 vided ;at the upper end -of the'caising 10, and to the T-ittin'g 24 isconnected a plpe 25 leading'to a' suitable source--not 'shown-'of water under pressure. 26 preferably has thereon a sliding 'rod 27 whichpasses through the stuffing box 28 on the T-litt-ing 24. The cable 26 may be opany `approved means not shown. v Y

vThe improved means 'for operatlvely connecting "or disconnecting the cable- 26 and the," drilling mechanism will now be de:

Scribed. A mandrel 29 provided with a j shoulder 30 has `its upper fend suitably se.

cured tothe lower end ofthe cable 26 and has its lower end portion adapted to fit into the converging upper'end portion of the h'ollow part 31 which latter is formed with longitudinal slots 32'land hasf-its lower end l suitablyattached 'to the upper end of the` bai` 16 of the drilling mechanism. -With the hollow kpart 31 is movably arranged a part 33 which has thereon a pin 35 extending laterally beyond the part 31 through the slots 32 and which is pressed upwardly by a spring 31 resting on the top end of the bar 16. Slips 36 resting on the top end of the part have one side thereofformed to lit against the converging upper end portion 37 of the part 3l and have the other side 38 thereof roughened to grip the lower end portion of the mandrel 29 when the spring 34 acts to move upwardly the part andthereby move the slips against the converging portion 37 of. the part 31, see Fig. 3.

ln drilling a hole 39 in the ground 4:0, fluid under pressure passes through the pipe 25, casing 10, and passageways 20, 21, and 22, and acts to soften the ground at the bottom of the hole and carry mud or loose dirt to the top and thence out of the hole. rlhe casing 10 may be raised, lowered, or held in adjusted position by the usual pipe lifting device or other suitable means, not shown. As the hole 39 is deepened sections of casing may be added at the top of the lhole by rst lowering the casing 10 to have the shoulder 12 engage the pin 35 and move downwardly the part l33 against the spring 34 so that the slips 36 can move downwardly out of engagement with the mandrel 29, see Fig. 4, and then unscrewing the if-fitting 24 and raising the cable 26 out of the casing 10 until the shoulder 30 engages the lower end of the stuiiing box 28 and lifts the T- litting out of the way, whereupon the additional sections may be connected to the top of the casing. The shoulder 23 engages with the upper end of the stuffing boX 11 when the cable 26 is operatively disconnected from the drilling mechanism. When sections are joined to the casing 10, the same may be lowered in the hole 39 and the fitting 24 may be screwed on the top thereof and the cable 26 may be let down to haveA the mandrel 29 enter the converging portion-37 of the part 31, whereuponV the casing 10 may be raised to raise the shoulder 12 out of engagement with p the pin 35 to allow the spring 34 to act to move the part 30 and thus cause the slips 36 to be crowded between the converging portion 37 and the mandrel 29 to grip the latter. l

The form of construction which has been particularly illustrated and described ad- `such changes and modifications as do not depart from the spirit and scope of the invention which is defined in the appended claims.

iaaasae ll claim:

1. lln combination in percussive drilling apparatus, a casing, a stuiing box at the lower end of the casing, a T-itting at the upper end of the casmg, a pipe on the T-fitting for conducting fluid underpressure, drilling mechanism including a stem passing slidably through the stuffing box and provided with a passageway, a bit on the lower end of the stem having passageways in communication with the rst mentioned passageway, said bit being greater in width than the diameter of the casing, and means for operating the drilling mechanism.

2. ln drilling apparatus, the combination of a casing, drilling mechanism disposed in` the casing and including a stem extending beyond the lower end of the casing, abit on the lower end of the stem, a shoulderv on the stem, means at the lower end of the casing for the shoulder to bear against to support the drilling mechanism, a cable, and means for operatively connecting said cable with' i cable adapted to it into the hollow part,

automatic means for moving the slips against said converging portion, and a pin engageable by said shoulder to render the automatic means inoperative.

4. The combination of a casing provided with a shoulder, drilling mechanism disposed in the casing, a hollow part thereon provided -with slots and with a converging portion, a spring-pressed part arranged in the hollow-part and having a pin thereon extending through said slots and adapted tobe engaged by said shoulder, a cable having a mandrel thereon adapted to it into the hollow part, and v slips disposed on the spring-pressed part and adapted to grip the mandrel when positioned adjacent to said converging portions.

lin testimony whereof, l have signed my name to this specification in the presence of two subscribing witnesses. at Los Angeles, county of Los Angeles, State of California, this 19th day of June A. D. 1914.
