COLLAPSIBLE ROTARY WELL DRILL.'
Application lcd January 9, 1922. Serial No, 528,046.
To all whom t may concern.'
Be it known that L FREDERICK A. VVIDMER, a citizen of the United States, residing at Corsicana, in the county of Navarro and State of Texas, have invented certain new and useful Improvements in Collapsiblc ,Rotary Well Drills, of which the following l is :i speciiication.
This invention relates to bits for well drilling and it pertains more particularly to a bit of this character designed for use in drilling wells by the rotary drill system.
In the rotary system of drilling wells the' well drilling bits are screwed onto the well casingor drill pipe which is' rotated and the bits cut through the rock or hard strata and when necessary to remove the bitsfor sharpening the drill pipe must be taken out of the well. To obviate this removal of the drill pipe I have devised a well drilling bit of collapsible form which may be locked to the end of thev drill pipe and so constructed and arranged that the bits can be detached or unlocked and removed from the drill pipe for' thepurpose of repairs or sharpening without removing the .drillpipe or casing. Further, the bits are constructed with as few parts as practically possible consist.- ent with strength, durability and practical use and manufacture. Y
The invention will bemore fully understood by reference to the following description, taken in connection with `the accompanying drawings, forming part hereof, in which- Figure l is an elevational view, partly 'in longitudinal section, of'a" portion of a -drill pipe embodying the invention and showing the improved collapsible bits in position therein. i
Figure 2'is an enlarged detail longitudinal sectional view of the drill pipe taken lower down and showing the connection of the drill bits and drill shank and lockingmeans with the bits in operative position.
Figure 3 is a cross-sectional view'taken on line 3 3 of Figure 2. l
Figure 1t is an elevational view of a tubular member or section of pipe scre'wedonto the plunger, with bail for attaching to a cabel for removing the bit, the pipe or tubue lar member in broken formation andA partly sectibned.
Figure 5 is is an elevational view of the lower end of the device, the bits removed.
improvements in .t1-ating in detail one of the bits,
Figure 6 is a, detail view in side elevation of one of the position. i
Figure 7 is a longitudinal sectional view of the devicewith illustrating the y bits for removal from the drill pipe.
Figure 8 is a partial longitudinal sectional view taken on the line 8-8 of Figure 2.
Figure 9v is a side elevationalviw, illusan Figure 10 is a cross-sectional view taken onthe line 10-10 of Figure 8.
Referring more in detail to .the drawings, l denotes the lower end of a drill pipe the in collapsed position,
inside diameter of which is enlarged shown in F ieures 2. 7 and 8 for the insertion of an end'member or nose 2 which is,
screwed therein. The nose 2 is hollowed down to point 3 as atei, see Figure 5, for allowing the bits to keys for locking the bits in part broken away and beyond which' it is slotted l be projected therethrough. The -nose is also slightly conical.
A bit shank 6 is hollowed at 7 downto a shoulder /8 upon which rests a spring 9 andv for the upper part,
is provided with ai nut 6al of the spring. The lower end of the shank 6 is slotted as lwill be seen by reference to 1 Figure 8 for'the drill bitsl0-10, and profor the locking keys.
viding alsoa recess l0a 11-11 one of which is shown in detail in Figure 6. These-keys'hav'e slots 112L and are supported by the pins 11b eachkey having two slot-s .with the keys overlapping each other as 'illustrated in Figure inner facesof these bits, likewise the nose 2, 'are provided with channels or ports 14 vfor thecirculation of' water through the 'drill pipe.
Figure 2 illustrates the bits in operative position and in Figure 7 the bits are shown in collapsed position The bits l0-l0 are arrangedto lie one y Within the shank 6 is a plunger 15 with a wedge-shaped end 16 by means of whichthe keys 1L-'1l are moved apart, the wedge passing betweenv the keys. 17 is a bushing closing the upper end of the tubular'shank G and centralizing the plunger therein.
Screw-threaded upon the upper'- end of the plunger 15 is a tubular member 17 which may be of several sections of pipe and which has a bail lS-by, means of vwhich the plunger, bits and shank are removed from the well.
In practical operation the Vnose 2 is screwed onto the lower end of the drill pipe section land the member 17', to which "is attached the plunger, and bit shanks 6--6, carryingthe bits lO-l0, are inserted into thepipel.
In normal position the keys 11.--11 are spaced apart as shown in Figure 7 with the end of the plunger therebetween. -weiglit ot the plunger and parts'will cause lthe wedgeshaped end 1G of the plunger to torce the keys downward until the shoul-v ders thereof, 16", have passed into the recess a, Vwhereupon the keyswill be forced further apart and the plunger will move upon and against the bits and torcethem outward into the position depicted in Figure 2. The object of the spring 9 Ais to provide' a cushion so that the plunger will'not yso Vin combination with the drill pipe, comprising a hgll'owed shank member to which the bits are removably attached, a plunger car- 'ried in the hollowed shank, a spring on the The' plunger, means for connecting the plunger to a cable, keyslbetween the plunger and bits vand so arranged that when the device is lowered into the well the plunger and shank will move thekeys downward and apart and cause them to vspread the bits into operative position and lock them therein.
2. Adrilling bit for rotary well boring in combination with the drill pipe, comprising a shank within the drill pipe to which the bits are removablyv secured, a 4plunger within the shank, keys actuated by the plunger and shank yand so arranged that when the plunger and shank are pushed downward the keys willbe shoved apart and against the bits to' move them into operative position and locked by said keys.
3. A collapsible bit for rotary well drilling in combination with the drill pipe, comprising a shank member, bits removably securedthereto, a plunger having means for connection with the well cable and recipro-I eating within the shank, drill-bits removably -attaehed to'the shank, a nose or end member secured to tlieend ot the drill pipe and through which the bits' project, slidable keys between the bits and plunger and a recess in the casing or drill pipe adjacent V the keys, said parts arranged so that the plunger and shank will collapse and extend the. bits and said keys will lock and release them, when the bits are lowered into and removed from the well.
In testimonywhereofl I have signed my name to this specification.
