ROTARY DRILL Carl E. Casperson, Tulsa, kla.
as its object the provision of improved means for rotating a drill stem.
In accordance with the present invention, such a means can be made up of new, salvaged or discarded standard motor truck parts, thus making it an easy matter to replace the parts in case of breakdown or wear.
The invention, together with its objects and advantages, will be best understood from a study of the following description taken -in connection with the accompanying drawings, wherein:
Figure 1 is a View in side elevation illustrating the invention mounted on a truck.
Figure 2 is an enlarged detail sectional view through lthe mechanism for rotating the drill stem.
Figure 3 is a bottom plan view of a collar.
Figure 4 is a top plan View showing somewhat diagrammatically the mechanism for taking power from the transmission of the motor truck.
Figure 5 is an enlarged view partly in section and partly in elevation of the mechanism shown in Figure 4.
Figure 6 is a detail View taken substantially on the line 6 6 of Figure 4. d
My invention isespecially adapted for use with portable well drilling rigs adapted to be mounted on a truck to be easily transported from placev to place.
Thus, in the drawings it will be seen that 5 indicates generally a conventional motor truck, while the reference numeral 6 indicates generally a tower which is pivotally supported on the truck 5 as at through the medium of brackets 8. For supporting the tower 6 when the same is in the horizontal or dotted line position shown in Figure 1, which is the position the tower will occupy when the rig is being transported from place to place, there is suitably mounted at the forward end of the body of the truck a suitable rest 9.
The usual drill pipe or, as it is commonly known, Kelly pipe forming part of the drill mechanism is indicated by the reference numeral I0 and at its upper end is provided with the usual swivel I and the suspension cables I2 whereby the pipe I Il is connected to the usual hoisting and lowering cable I3. able pulleys I4 mounted in the upper end of the tower 6 and is windable on a suitable winch I5 (see Figure 5) suitably mounted in the box or body of the truck. The water or other cleaning uid which is used for flushing the drill bit i6 is fed to the Kelly rod I0 through the usual ilexible tubing or piping I'I connected in the usual The cable I3 is trained over suit- 1934, Serial No. 740,991
(Cl. Z55-19) manner with the pipe i0. A pump for pumping the water so used is also mounted in the body of the truck 5 and is indicated by the reference numeral i8.
The drill stem is indicated generally by the reference numeral i 9 and is connected to the lower end of the Kelly rod Iii in the usualmanner as indicated generally at 2li.
My improved mechanism for rotating the drill comprises a sectional housing 2| which, in the present instance, is made up of sections used in the construction of a diierential housing for motor vehicles. On the tubular part 2|a of the housing 2| is a. collar 22 provided internally with the shoulder 23 between which and the end of the part 2|a of the housing is a thrust bearing 2li that is also held in position through the medium of a. suitable bushing 25.
A somewhat similar collar 26 is provided on the tubular end 2lb of the housing or casing 2| and also is equipped with a shoulder 2l, thrust bearing 28 and bushing 29. Extending through the housing or casing 2| is a tube 30 onto the ends of which are screwed as at 3| and 32 the aforeumentioned collars 22 and 26. Welded or otherwise iixedly secured to the sleeve or tubing section 30 is a ring gear 33 that is, or may be nothing more or less than the driving gear such as, for example, is used in differentials for Ford motor trucks.
The gear case 2| is also provided with the usual pinion pilot bearing 34, pinion bearing and pinion bearing cup 36 supporting in the usual manner the driving pinion 3l that is in constant mesh with the ring gear 33.
I also make use of the usual drive shaft coupling 38, bearing nuts 39 and bearing sleeve 40.
The mechanism just described -is suitably mounted on the rear end of the truck 5 and is adapted to have passed through the sleeve 30 the Kellyrod I0 which, as will be understood, is of the usual cross sectional shape, namely, square.
For operatively connecting the sleeve 30 with the rod I0, there are provided a pair of complemental slips 4I that are accommodated in the bores of the collar 22 and the upper portion of the sleeve 30, the slips 4| having rounded or con- Vex outer surfaces and squared or substantially rectangular inner surfaces orgrooves 42 which accommodate the Kelly rod I0. Further, at the upper ends thereof the slips 4| are provided with lateral anges 43 that are accommodated in a groove M extending transversely of and provided in the upper end of the collar 2v2. Thus it will be seen that rotation of the sleeve will be transmitted to the rod I0 for rotating the drill parts I6 and I9, the part I9, or stem of the drill, being, as before stated, connected as at 20,' with the lower end of the Kelly rod I0. e
Further, in accordance with the present invention, the coupling 38 serves to operatively connect the pinion 31 with a shaft section 45 that is driven through the medium of chain and sprocket means 46 from a shaft 41, shafts 45 and 41 being suitably mounted on the truck. For placing the shaft 45 into and out of driving engagement with the shaftv 41 there is provided as a part of the chain and sprocket mechanism 46 a suitable clutch 48 that is operated by thedriller through the medium of a suitable control rod 49.
For driving the shaft 41 there is suitably associated with the transmission 50 of the truck apower take-off device 5I which is suitably connected as at 52 with the shaft 41.
For driving the pump I8 from the shaft 41 there is` provided a chain and sprocket mechanism 53 including a suitable clutch 54 operated through the medium of a control or operating rod 55. For driving the winch I5 from the shaft 41 there is provided suitable power transmitting mechanism including a chainl and sprocket mechanism 56 embodying as a part thereof a clutch 51 which is also equipped with a suitable control rod (not shown).
From the above it will be apparent that when the parts are in the position shown in Figure 1,
' power for operating the drill is taken through the medium of the mechanism just described from the transmission of the truck for driving the pinion 31 which, being in mesh with the ring gear 33,- rotates the sleeve 30 resulting in a' rotation of the drill rod I0 and the associated drill.
To insure lubrication of all moving parts of vthe device, the casing 2| will be fluid tight and will retain oil to a, suitable level. To this end i there is provided within the casing 2l an oil retaining tube 60 which is disposed concentric to the tube 3U and spaced relative thereto. The tube 60 is secured at one end in any suitable manf ner within the casing 2| in substantial alinement.
with the extension 2lb and extends inwardly to within a short distance of the flange 33 as shown in Figure 2. With the tube 60 so arranged in the casing, the casing or housing 2l may be lled with oil up to the top of the tube 6U which will create an `oil level sufficiently high to submerge the pinion 31 and the tooth-equipped part of the ring gear in oil, thus supplying sufficient lubrication to all parts-of the rotary drill except the 'caps 22 and 26.
What is claimed is:
1. In a drilling mechanism, a gear case, a sleeve rotatably mounted therein, gearing Within the case and operatively connected with the sleeve for driving the latter, a collar on one end of the sleeve havingy a circular bore, and also provided on one end with grooves at diametrically opposite sides of the bore, and a pair of complemental slips fitting in'the bore of the collar and 'having at one end lateral flanges engaging in the groove of the collar; said collar also having a skirt portion telescoping a fixed portion of said casing and a thrust bearing arranged within the confines of the skirt portion of the collar at one end of the fixed portion of said casing.
2. In amechanism of the character described, a casing, a tubular member extending through 4said casing having ends projecting beyond the at one end lateral flanges engaging in the grooves of said one collar, and an oil tube fixed within said casing concentric to said tubular member, said oil tube being fixed at one end within one end of said casing and terminating at its free end in spaced relation to the relatively opposite end of said casing.
