WELL-DRILLING MACHINE.

Application filed June 22, 1918.

To all whom it may concern:

Be it known that we, l/VILLIAM L. DAYTON and JOHN M. SCOTT, both citizens of the United States of America, residing at Fort lVorth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Well-Drilling Machines, of which the following is a specification.

Our invention relates to well drilling machines, construction and mine hoisting machines, freight and passenger elevators, and various machines using derricks and cranes, and the object is to provide improvements and attachments which are relatively simple in construction and operation and which is provided with certain swinging gravityactuated devices by which the and expense and to provide improvements by which the machine is greatly increased in efficiency. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this appli cation.

set forth will further 5, 6, 7, and 8.

The machine is mounted on a wheeled truck, being supported thereon by the side beams 1 and 2.

. For drilling, a master wheel 12 is rigidly mounted on a shaft 13 which is journaled in the uprights 14 which are rigid with the frame members 1 and 3 and 2 and 4. Means are provided for driving the wheel 12. The wheel 12 is provided with internal gear teeth. or cogs 15. A power shaft 16 is journaled in uprights 6 and 8 and provided with a power pulley 17 rigid therewith. A balance wheel 18 is mounted on the other end of the shaft 16. A pinion 19 is rigid with shaft 16 for transmitting the power from this shaft. The pinion 19 meshes with and drives a cog wheel 20 which is rigid with a shaft 21. The shaft 21 carries a pinion 22 rigid therewith. The pinion 22 meshes with and drives the internal gear wheel 15 for elevating the drill 23. The master wheel 12 is a cog wheel and meshes with and drives a pinion 24. The pinion 24 is rigid with a shaft 25 and drives this shaft when the pinion 24 is in mesh with the master wheel 12. The shaft 25 carries a. spool 26 rigid therewith for winding the cable 27 which brace the uprights has one end attachedto wheel or spool 26 and the other end attached to the drill 23. The cable 27 runs from the spool 26 under a shaft 28 which is provided with an antifriction roller 29. The cable 27 then runs over an idler 30 and then down under an idler 31 and then up over an idler 32 and then down to the drill 23. This describes the course of the cable and the means for operating the same for elevating the drill.

When the drill has been mounted in the manner described, it is actuated by the following described mechanism. The pinion 24 is thrown out of mesh with the cog wheel 12 by a hand lever 33 which is provided with a. fulcrum 34 pivoted in a bearing member 35 which is attached to the crossbar 9. The bearing member 35 has notches 36 in the upper edge and a spring-actuated dog 37 carried by the lever 33 engages one of the notches 36 to hold the lever33 in position. A link bar 38 is pivotally connected to the lever 33 by a pivot bolt 39 which projects through the bearing member 35 and the bearing member 35 has a. curved slot 40 for the movement of the pivot bolt 39. The

link bar 38 ispivotally connected to a bellcrank lever 41 which is fulcrumed on a bar 42 and which engages the shaft for throwing the pinion 24 in and out of mesh with the cog wheel 12. The dog 37 when in one notch 36, will cause the levers to hold the wheel 24 in mesh with the cog wheel 12, and when in the other notch 36, will cause the levers 33 and 41 to hold the wheel 24 out of mesh with the wheel 12. The upright 14 has an elongated bearing opening to permit adjustment of the shaft 25. At the required time the wheel 24 is thrown out of mesh with the wheel 12 so that the drill can be actuated.

The roller 30 is carried by a swinging link 43 and this link is carried by a walking beam 44 which is fulcrumed in uprights 45 which are attached to the beams 1, 3, 2, and 4. The walking beam 44 carries a cam arm 46 rigid therewith. A crank 47 is rigid with shaft 13 and carries an antifriction roller 48. The cam arm 46 is attached to the walking beam 44 by arms 49. WVhen the shaft 13 is driven by the wheel 12, the crank 47 with its roller 48 will engage the cam arm 46 and So rock the beam 44 which will by means of the link 43 and roller 30 lift the drill 23 and let the drill fall at regular intervals.

A swinging weight 50 is used to coiiperate with the driving mechanism for actuating the drill. The weight 50 is pivotally connected to the walking beam 44 by means of a bar 51 which has a lug pivotally connected to arms 53 which are attached to the beam 44. A bellcrank lever 54 is fulcrumed on the beam 44 and pivotally connected to the link 43 and a. rod 55 is pivotally connected to the lever 54 and the bar 51 above its pivotal connection with the beam 44. In operation, the crank 47 will engage the cam arm 46 and thus bear the end of the walking beam 44 downwardly at that end. Thiswill raise the link bar 43 and thus elevate the drill. \V'hile this operation is going on, the drill will be pulling on the lever 54 and the lever 54 will pull on the rod 55 and this rod will pull on the bar 51 and tend to raise the weight 50 and does raise this weight so that the weight 50 will be elevated by the weight of the drill. The weight 50 will thus cooperate with the cam operated end of the walking beam to aid in raising the working end of the beam which action will elevate the drill. As the weight is gradually raised the leverage will be increased and the work accomplished by the weight will be correspondingly increased. As the bar 51 is appreaching a position to be in line with the beam 44, the leverage is being automatically increased and this increase infieverage tends to balance the weight or loa of the drill. The driving mechanism can be operated with much less power than would be required without the weight. When the roller 48 passes far enough it will release the cam arm 46, the work end of the beam 44 will drop downwardly and the weight 50 will also drop so that the work end of the beam 44 will drop more freely. This lets the drill fall to do its work.

A brake mechanism is provided to regulate the speed of the machine. A brake wheel 56 is mounted on shaft 13 and a strap brake 57 is passed around the wheel 56 and attached to an upright bar 58 which is attached to the beams 1 and 3. The other end of the strap 57 is attached to a brake lever 59 which is fulcrumed on the upright 58. The lever 59 extends back to the work end of the machine for the convenience of the operator and is retained in place by a bracket 60. The lever 59 is held in the elevated inoperative position by a spiral spring 61. The brake is operated by hearing down on the end 62 of the lever. hen it is released, the spring 61 replaces the lever to inoperative position. When the machine is drilling the spool 26 is locked against revolving by the Worm pinion 72 hereinafter described.

hen the beam 44 is not to be used in drilling, it is locked rigid in a horizontal position by an arch lock 63 which is pivotally mounted on the beams 3 and 4. This stop or look is actuated by a lever 64 which is fulcrumed on the inside of the upright 5 and pivotally connected to a link bar 65 which is pivotally connected to ar crank 66 which is rigid with the lock 63. The stop can be operated by using the lever 64. The crank 47 is loosely mounted on the shaft 13 and is locked thereto by clutch members 65 and 66. Simultaneously with the locking of the beam 44 against movement the crank '47 is released from shaft 13 by shifting the clutch member 66 out of mesh with clutch member 65. This is done by a bell-crank lever 67 which is fulcrumed on a bracket 68. One arm of the lever 67 engages a collar 69 which is integral with the clutch member 66 and the other arm of this lever is connected to the crank 66 by a link bar 70. The clutch members are held normally in mesh with each other by a spring 71. When the beam 44 is locked against movement and the clutch members 66 and 67 are disconnected the machine is used for bailing the well or for placing or replacing casing or for other purposes.

The length of the stroke of the drill is varied by varying the length of the cable 27. Means are provided for winding the cable 27 more or less on the spool 14. The pinion 24 is thrown out of mesh with cog wheel 12 by lever 33, as above described. At the same time the pinion 24 is thrown out of mesh with cog wheel 12, the pinion 24 is thrown in mesh with a worm wheel 72 which is provided with a shaft 73. By means of the pinion 24, worm wheel 72, shaft 73, and a crank 74 for shaft 73, the spool 26 can be revolved in either direction for making the cable 27 throw more or less to vary the stroke of the drill, and for feeding. the cable to the drill as the drill goes deeper.

When the machine is not being used for actuating the drill, the speed of the wheel 12 and shaft 18may' be driven much faster. A cog wheel 75 is rigid with the wheel 12. The pinion 22 which, when the machine is drilling, engages the internal cog wheel 15, may be shifted to engage the cog wheel 75 which is much smaller in diameter than the internal gear wheel 15. This will increase the speed of the shaft 13 without increasing the speed of the shaft 21. The shifting of the pinion 22 is accomplished by a lever bearing 76 which is fulcrumed on a bracket 77 and which engages the hub of pinion 22 loosely. The lever bearing 76 is actuated by a link bar 78 which is pivotally connected thereto and pivotally connected to an upstanding crank 7 9 which is rigid with a rocker shaft 80'. The-shaft 80 is actuated by a link bar 81 which is pivotally connected to an upstanding crank 83" which is rigid with shaft 80 and pivotally connected to a lever 8-2 which is aduplicate inconstruction of the lever 33, shown in Fig. 5, and has similar equipment. The lever 82 can be thus used to shift the pinion 22 into mesh with internal gear wheel 15 or into mesh with the pinion 75 for changing speed and for reversmg purposes.

The machine is provided with a spool or drum 8 1 which is journaled in bearings 85 and 86. The spool 8i is driven by a pinion 87 which is adapted to be thrown in mesh with cog wheel 12. The bearing 86 has an elongated bearing opening for the spool shaft 89 and a link bar 90 is pivotally connected to the shaft 89 and pivotally connected to a lever 91 which is fulcrumed on the upright 7. The lever 91 may be used to throw the pinion 87 in mesh with the wheel 12 for bailing the well. The lever 91 will hold the shaft 89 in whatever position that may be required.

The variation shown in Fig. 6 consists in substituting a friction drive for the pinion 2'2 and cooperating gearing. A friction pinion 92 is provided and an internal friction wheel 93 takes the place of gear wheel 15 and a friction pinion 9st takes the place of the pinion 75.

The variation shown in Fig. 7 consists in using wrist pins 95 instead of the crank 47 on shaft 13. The wristpins may be carried by the master wheel. The cam arm 16 with the attaching arms 49 is attached to the walking beam 44 and the devices operate in the same manner, asthe arm 16 and crank 17 with the rollers 48.

Various other changes in the construction,

proportion, and arrangement of the several parts may be made without departing from our invention.
