-Thisjinventlon relates to' new `and useful improvements drills and the primary object of the present invention is to provide a drillingapparatus including novel and improvedA means whereby thesame is particularly applicable for lateral drilling inthe sides ofV a drill hole.
Another importantobject of thepresent inventionfis toprovide a lateral drilling apparatus includingI novel andimprovedmeans for suspending thei'apparatus a selectedA predetermined and scaled-distance fromA the ground surface.
A further Aobject of the present invention is to provide a drilling apparatus for boring lateral openings into the walls of a drill hole including a housing having an arcuate integral extension at one end that is formed with an opening throug'hwhih auexible bit holdingvshaft is extendabley at right angles tothe longitudinal axis ofV` the drill hole.-
A still further aim of the present invention is to provide adrilling apparatus that is simple and practical in construction, strong and reliable in use, small andv compact in structure, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for'whichlthe same is intended. e
Other objects and'advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being hadto thehaccompanying drawings forming part hereof, wherein like numerals refer to like tion, and with parts thereof broken away and shown in section;
Figure 5 is an enlarged, fragmentary longitudinal vertical sectional view taken substantially on the plane of section line 5-5 of Figure 4; and,
Figure 6 is an enlarged, fragmentary longitudinal vertical sectional view taken substantially on the plane of section line 66 of Figure 1.
Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present UN-ITED STATES .PATENT orifice invention, the numeral nular retaining flange l2 that removably engages a supporting plate I4 which is secured to the retaining ilange I2 through the medium of Va plurality offasteners I6,- This supporting plate I4 is provided with an internally threaded socket.V or opening` I8 that receivably engages the/lower externally threaded end of a lower pipe section 2l). Integrally formed with the housing l0, is an arcuate lower extension 22 ha-ving lan opening 24 formed in its outer extremity 2E. vFixed by bolts or the like 28 to the outer extremity 26 of the ex,-
tensi-on 22, is a holding ring 3l! that forces a packing washer 32 against an annular shoulder 34 integrally formed with the inner surface of the extensionV 22 adjacent the opening 24.
Projecting outwardly from substantially diametrically opposite sides of the housing I0, isa` Vpair of rigid ears 35 that pivotally engage the lower terminals 38 and 40 of a pair of hanger or suspension arms 42 and Meach of which are preferably formed of a plurality of sectionswhich" are pivotally` jointed as at 45. These arms 'in-I. clude upper sections 46 and 48, one of which for] example 46 is provided with graduations orf a scale 50.
Holding or gripping members 52 andjS piv-V otally carried by the upper sections 46' rand V48 engage the upper open end 55 of an outer casing 58 that extends into the well opening or lril1' hole 60. 1
porting shaftthat extends downwardly through the lower pipe section20, the housing IB, and f outwardly through the opening 24 in the extension 22. The upper terminal 'l2 of the flexible shaft l0 extends into a socket member 'I4 having a crimped or tapered open end 16. A rivet or the like 18 extends through the socket member 'I4 and the upper terminal 'l2 of the ilexible shaft 10. Integrally formed with the socket member 14, is a reduced, externally threaded stud that receivably engages an internally threaded recess 82 provided in the lower end of a sectional driven shaft 84. It is noted that the driven shaft includes a group of sections each of which is formed with a socket or threaded recess 82 in their lower ends and reduced externally threaded upper end I0 representsA a housing( open at its upper end and provided withran an?V portions 86 whereby the sections when assembled will be of a desired length to extend above the ground surface 88. The uppermost of the driven shaft sections, which will be referred to by the numeral 90, is preferably square in cross section to engage a square central opening 92 in a driven pulley 94.
Fixed on the ground surface 88 above the well hole 60, isan elevated supporting table that rotatably supports a bearing or drum 96 which is,
suitably secured to the driven pulley 94. The
driven pulley 94 is connected by an endless belt.
98 to a suitable drive pulley (not shown) that is driven by a suitable motor (not shown).
In order to reduce the weight of the shaft 90 acting upon the bit carried by shaft '10, there is provided a braking and balancing mechanism that is connected to the shaft 90 to support the same but in such a manner as to permit rotation of the latter, such as a bearing |02 carried by the shaft 90 engaging a bearing |04 mounted on a detachable shaft |00 carried by the pivot beam |08.
Obviously, other suitable means could' be vemployed for supporting the weight or a considerable-portion of the Weight of theshaft 90, such asa cable attached tothe top of shaft 90`and through swivels and pulleys to the drum with a known'fand conventional brake on the cable. Byv such an arrangement the shaft 90 maybe raised and the-speed rotation thereof controlled. Since the presentinvention -does not attempt to claim such a` conventional and known method, this latest apparatus is not shown.
In View of the foregoing description taken in conjunction with the accompanyingdrawingsit is believed` that a clear understandingof the'devicevvill be quite apparent to those skilled in this art. deemed' unnecessary.
It is to be understood, however; that" even' though there is herein shown and described a' preferred embodiment ofthe invention the' sameA is` susceptible to certain changes fully-comprehended bythe spirit ofthe invention as herein described and the scope of the appended claims'.
Having described the invention, what is claimed cured at one endin the upper opening of said.
housing, said tubular member being received in said-casing, a driven shaft mounted for rotation in said tubular member, a flexible bit supporting shaft secured to said driven shaft, said flexible shaft being received in said housing and having arportion projecting outwardly through the lower A more detailed description is accordinglyV opening in said housing, means for rotating said driven shaft, a pair of arms pivoted to and rising from said housing, and gripping members on said arms receiving the upper edge of said casing for supporting said housing and said tubular member relative to said casing.
2. The combination of claim 1 wherein said housing includes an arcuate tubular extension disposed at right anglestoy the tubular member and receiving said flexible shaft, andmeans carried by said extension and surrounding said flexible shaft tending to prevent the entrance of dirt into the housing through said extension.
3. The combination of claim 2 wherein said means carried by said extension includes an internal shoulder on said extension, a holding ring secured to said extension and spaced parallel to said shoulder, and a packing washer interposed between said shoulder and said holding ring.
4. A drill comprising a casing extendable into a drillihole and. having upperandlower edges.. a
housing suspended below thenlower edgeiofjsaid-v casing, said housing havingr upper and. lower.
openingstherein at rightangles-to each other, an; elongated tubular member secured at-.one-endin` the upperopening in said;housng, saiditubu1ar member being receivedin said'casing, at driven shaft mounted for rotation insaid tubularmem-f ber, a flexible bit supporting;shaft secured to said: driven shaft, said flexible shaft being received in:A said housing and havingl al portion projecting outwardly through the lower opening inl said housing, means for rotating said drivenshaft; ai. pair of ears projectingl fromV diametricallyopposite sides of saic'l housing, a pair-ofV hangerl arms having lower ends pivoted to saidfears, andi gripping members atrthe upper endsof said armsV receiving the upper edge of said casing-for` supporting said housing and said tubularfmember-y relative to said casing.
