COMBINATION DRILLING-RIG. i
Specification of Letters Patent.
Patented Feb. 1, 1916.
Application led May 19, 1915. Serial No. 29,128.
T 0 all 'whom t may concern Be it known that I, Rosoos W. SrErHENs, a citizen of the United States, reslding at Los Angeles, in the county of Los Angeles `and State of California, have invented a new and useful Combination Drilling-Rig, of which the following is a specification.
This invention relates to combination drilling rigs employed in the operations of standard and rotary drilling and a principal object of this invention is to facilitate to the maximum the constructionof wells and at the s ame time minimize the cost incident to said construction.
The advantages of this invention over other combination drilling rigs now in use in the oil fields are better understood when it is-borne in mind that, in the construetion of a well, the various operations of standard and rotary drilling, lowering and raising of the tools, and lowering and raising of the casing and drill pipe are not performed in any fiXed systematic order but are performed in anorder that is dependent upon the varying conditions arising from time to time from the start to the finish of the construction of the well. For instance, as an example, it is noted that the drilling of -a well is often facilitated by employing standard tools for working through some earth strata and by employing rotary tools `for working through other earth strata. v From the foregoing it is clear that 1n or-4 der'to minimize the time and cost of construction of wells it is of advantage to make provision for quick substitution of-one oper-4 ation for another, for maximum simplicity of construction and operation and for reliability of operation. This invention is designed to effect the foregoing.
This present invention differentiates from my prior invention of drilling rig patented to'me'August 11, 1914, No. 1,106,900, in
that in said patent the construction was such as to necessitate the'use of gripping jaws to aid in driving the rotary table in order to dispense with the use vof bevel gears employed for turning the turntable previous to said prior invention, whereas in this present invention I am enabled to dis-- pense with the gripping jaws and also with the bevel gears generally employed.
Itis 'understood that the rotary drilling table has to operate atrelatively low speed and requires a powerful turning force to rotate it, suchV force being considerably be- Awithout the noise and expense incident to the use of bevel gears and without the expense incident to the use of cable grips, that the table, bull wheel, draw works, walkingbeam-operating crank arm and sand reel can all be operated from a single engine and that the standard rig now in use in the oil fields may beutilized by merely adding thereto, I have provided a special construction including wire line transmission to the rotary table and have so arranged the various parts that said wire line transmission is effective to transmit the maximum amount of power from the engine to the turntable. The accompanying drawings illustrate the mvention Figure 1 is a plan view of the invention,
`a portion of the derrick and platform being broken away for clearness of illustration. Fig. 2 is a side elevation of Fig. 1.
There is provided a suitably constructed frame 1 having at one end a platform 2 and a derrick 3 which is partly broken away in the drawings to contract the views. The platform end of the frame 1 is provided with posts 4 which rotatably support a bull wheel 5 for the cable, not shown, used in raising and lowering the drilling tools, said bull wheel having a grooved band wheel 6 driven by an endless Wire line 7 that is rove around a grooved band wheel 8 on a crank shaft. 9.
The crank shaft 9 is journaled in bearings 10 mounted on standards 11 of the `frame 1, and said crank shaft is provided at one end with a crank arm 12 designed to be connected to the usual walking beam, not shown, for reciprocating'the standard drilling tools. The crank shaft 9 is provided with a -second band wheel 13 turned by a wire line 14, which is rove around a grooved sheave 15 adapted to be thrown into and sheave 21 to the band wheel 24, and the other lead of-said wire line passes in a straight line from the sheave 21 to an idler 26 mounted on an upright 27 of the frame 1, and said other lead passes diagonally relative to the long axis of the frame from said idler to the band wheel 24, said idler thus bending one lead of the wire line to one side of the frame. One strand of the wire line 23 is rove around a tightening idler 28, which is mounted on a standard 29 of the frame 1.
The crank shaft 9 is provided' with a sprocket wheel 30 driving a sprocket chainv 31 which engages a sprocket wheel 32 mounted on a shaft 33 of the draw works designatedin general -by the character 34,`said draw works having the customary high and low speed gearing 35, 36. The band wheel 13 is the frlction wheel 37 of a sand reel 38, said friction wheel 37 being adapted to be thrown into and out of engagement with the band wheel 13 by operation of the arm 39 inthe usual manner.
The clutches 16, 22 are operated by clutch rods 40, 41 respectively connected by crank arms 42 to transversely extending 'shafts 43l journaled in bearings 44 mounted on the frame 1, one end of said shafts being provided with operating levers v45, and the crank arms 42 are so arranged that when the operating levers A45 are turned in one direction, the clutches 16, 22 are thrown out of commission and that when the operating levers are moved in the opposite direction,
the clutches are thrown into commission.
' From the foregoing it is clear that in practical operation assuming that the engine 18 is running and that the operator desires to operate rotary drilling tools, he will throw the clutch 22 into commission to drive the wire line 23 and thereby turn therotary table and the drilling tools. 1f the operator desires to operate the standard drilling tools, he will throw the clutch 20 out of commission and the clutch -16 into commission to drive the wire line 14 and the crank 12 so as to reciprocate the drilling toolsin a manner well understood. When the operdraw works may be operated in either di-l ator desires to draw the casing or drill pipe,
he will do so in the usual manner through the agency of the draw works 34, which arev being driven by reason of the clutch 16 being 1n commission. If the operator wishes 'to raise or lower the tools, he will put. the
bull wheel into yoperation through the agency of the clutch 16, and will proceed in the usual manner to raise or lowerthe tools, it being understood that the bull wheel and rection by appropriate operation of the engine-reversing mechanism well understood rvided adjacent its' periphery with and therefore not necessary to be shown in the drawings.
. By the construction described above, I am enabled to eiiect the various operations'in the construction of a well by a single engine instead of employing two engines as heretofore, and have also otherwise simplified the drilling rig so as to minimize the liability of said rig getting out of order.
It is noted that the above described construction makes it possible to use but one hoist instead of twol and also makes it possible t0 drive the rotary table, crank shaft and bull wheel through the agency of reliable and comparatively yinexpensivel wire line transmission in lieu of unreliable rope belts, expensive sprocket wheels and chain, and expensive bevel gearing heretofore in use, thus minimizing the cost of construction -shaft and provided with a crank`v arm for connection to a walking beam to operate standard tools, two band wheels onsaid crank shaft, a rotary table between the bull.
wheel and crank shaft provided with a band wheel, a wire line rove around one of the sheaves and one of the band wheels, a second wire line rove around the second band wheel and bull wheel, a third wire line rove around the second sheave and around the band wheel of the rotary table, draw works between the crank shaft and rotary table, and driving connections between the draw works and crank shaft.
2. A combination drilling rig comprising a frame,a derrick at one end of the frame, a bull wheel mounted transversely on the frame at one side of the derrick, draw works fmountedftransversely ont' the frame atl-1anthe bull wheel andv draw works, a power shaft mounted transversely at the other end of the frame, an engine-to turn said power shaft, sheaves, means operative to throw either one of the sheaves into operative relation to the power shaft, a crank shaft mounted transversely on the' frame between the draw works andpower shaft, two wheels on the crank shaft, driving connect-ions at one side of the frame between one ofsaid wheels and the bull wheel, other driving connections at vsaid side of the frame between the secondy wheel and one of the sheaves, and a wire line at the other side of the frame rove around the other sheave and the rotary table.
3. A combination drilling rig comprising a frame, a power shaft mounted at one end of the frame, an engine to drive said power shaft, sheaves, means on the power shaft to throw the sheaves into and out of operation,
a bull wheel lmounted at the opposite end of said frame, a crank shaft mounted on the frame between the bull wheel and power shaft and provided with a crank arm for connection to a walking beam to operate standard tools, two band wheels on said =c1-ank shaft, a rotary table between the bull wheel and crank shaft provided with a band wheel, a wire line rove around one of the sheaves and around one of the band wheels, a second wire line rove around the second band wheel and bull wheel, a third wire line 'rove around the secondsheave and around the band wheel of the rotary table, an idler -rotatively mounted near one side of the frame, one lead of said third wire line pass'- ing in a straight line from its sheave to the band wheel of thel rotary table and the other lead of said third wire line passing in a straight line from its sheave to said idler and thence vdiagonally relative to the long axis of the frame lfromsaid idler tothe band wheel ofthe rotary table, draw works be@ tween the crankshaft and rotary table,v and driving connections between the draw works and crank shaft. v
In testimony whereof I have hereunto set, my hand at Los.l Angeles, California, this 18th day of May', 1915.
