HYDRAULIC DRILL AND BE AMER.
Specification of Letters Patent.-
Patented Aug. 6, 1907.
Application filed June 5.1906. Serial No. 320,350.
To all whom it may concern: 4
Be it known that I,HERMAN Bnnnnns'onnin'r, a citizen of the United States, residingv at Anaheim, in the county 01 Orange and State of California, have invented new and useful Improvements in Hydraulic Drills and Reamers, of which the following is a specifi cation.
My invention relates to drilling or reaming toos for oil or other Wells and an object thereof is to provide a tool that may be used with a rotary drilling rig. I
Afurther object is to construct a tool that can'be locked within the casing and carried thereby and which may be readily put in or withdrawn therefrom. H I accomplish these objects by means of the device described herein and illustrated in the accompanying drawings forming a part of this specification in which:
Figure 1.- is a central vertical. section of my im- 2.-is a plan vicwof the shank, Fig. 3. is a section taken on line 33 of Fig. 1 looking-in the direction indicated by the arrows. Fig. 4. is a section taken on line 4-4 of Fig. looking in the'direction of the arin form and has a central and preferably cylindrical opening 13' which extends downwardly and is enlarged a portion of the way to form a shoulder 14 for the coiled spring 15 to bear against. This spring is for the purpose of supporting a slip rod 16 and i's'threaded on its upper end to receive a nut 17 against which the outer end of the spring bears. Near the lower end of the rod 16 is a key 18 which projects on either side and w hen in their operative position are prevented from becoming disengaged from the mandrel 12 and the key 18 by the lower portion of the extension shoe 25. The
upper portion of the slots 22-are .preferably dove-tailed Fig. 7." is a perspective view of a Fig. 9- is a cross section illustrating-the method with the sides of the mandrel.
' as at 23 for the reception of the tapered tongued look ing wedges 24. These wedges'ar'e for the purpose of them into their cutting or drilling position.
The upper portion of the shank of the tool and the mandrel are provided with oppositely disposed grooves 28 which in this instance are shown as segmental, by means of which the water may be introduced into the bottom of the well to free it of the detritus'which is forced up ardly between the outside of the casing and the well.
The operation of 'the device is as follows: When it is desired to begin the operation of drilling the cutting bits are pulled downwardly by means of hooks placed in'the holes 29 which are located in the lower part of thebits until the diameter of the bits equals the inside diameter of the casing. A pin 30 is then inserted in the aperture 31 of the mandrel 12, passing through the aperture 31 in the slip rod 16 thus holding the bits 20 in a closed position until they have been inserted in the casing 27. The tapered wedges 22 that work upwardly and downwardly in the tapered grooves in the mandrel rest on top of the cutting bits and follow them downwardly until the outside faces are flush The tool is then lowered into the casing and the .pin 30 which was inserted .in the apertures 31 and 31 of the sliprod and mandrel is then withdrawn so that the cutting bits will assume their cutting or drilling position. The tool is then lowered further into the casing until the tapered wedges 24 rest in the'grooves 26 in the extension shoe. The casing is then rotated in the direction of the arrow in Fig. 6, the tapered locking Wedges Wedging in the grooves inthe extension shoe and locking it firmly thereto. When it is desired for any purpose to withdraw the tool from the well; the casing is rotated Having described my invention what I claiin as new and desire to secure by Letters Patent is:
1. A -drilling-tool comprising ahollow extension shoe having a plurality of cam groovesfon the inner face thereof; a hollow mandrel having longitudinal tapered grooves in the lower end thereof for the reception of the cutting.
bits; cutting bits slidingly mounted in said last grooves;
I and means secured to the mandrel adapted to enter the drel'adapted to enter the grooves in the shoe whereby they I grooves ln the shoe whereby the, mandrel may be locked within the extension shoe. l
2. A drilling tool comprising a hollow extensionshoe having a plurality of calm grooves on the'inner face thereof; a hollow-mandrel having longitudinal tapered grooves in the lower end thereof for the reception of the cutting .bits; cutting blts slidingly mounted in said last grooves;
means secured within said mandrel to control the movement of the cutting bits; and means secured'to the'manmandrel may be locked within the extension shoe.
A drilling tool comprising a hollow extension shoe having a plurality of inclined cam grooves: 'on the inner face thereofi; a ho llow mandrel having longitudinal ta peredgrooves in the lower. end thereof for the reception of'the cutting bits; cutting bits slidingly mounted in said last grooves; spring'controlied means secured within said mandrel adapted to control the movement of the cutting.
bits; and meanssccured to the mandrel adapted to enter the grooves of the extension shoe, whereby the mandrel may be locked within'the extension shoe.
4. A drilling tool comprising a hollow extension shoe having a plurality of inclined cam grooves on the inner face thereof; a hollow mandrel having longitudinally ta .pered grooves in the lower end thereof cutting bits slidingly mounted in said Inst grooves; locking' means slidingly secured in the upper end ofsaid longitudinal grooves and adapted to enter the cam grooves of the extension shoe whereby the mandrel may be locked within the shoe; and-spring controlled means secured within said mandrel adapted to control the movement of the cutting bits and locking means.
o 5. A drilling tool comprising a hollow eitension shoe having 'a plurality of inclined cam grooves on the inner face thereof; a hollow mandrel having oppositely disposed longitudinally tapered grooves in the lower end thereof; cutting bits slidingly mounted in said last grooves; locking means slldingly secured in the upper end of said longitudinul grooves and adopted to. enter the cam grooves ofthe extension'shoe whereby the mandrel may be locked within the shoe; and spring controlled means secured
