WELL BORING AND DRILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 236,492, dated January 11, 1881.

Application filed June 1, 1880.

To all whom it may concern Be it known that I, OHARLEs HARMON, of the county of Seneca and State of Ohio, have invented certain new and useful Improvements in \Vell Boring and Drilling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference beinghad to the accompanying drawings, which form part of this specification.

My invention relates to well boring and drilling machines; audit consists in an adjustable walkingbeam, which, in combination with a cam, is adapted to increase or lessen the drop of the drill; also, by an arrangement of pulleys, whereby the drill itself is permitted to drop through a greater space than that through which the end of the walking-beam drops at the same time; also, in mechanism by which the drill is lowered as it cuts its way through the rock or earth; also, in an arrangement by which the feeding mechanism is disconnected and the drill permitted to drop until it reaches the bottom of the hole; also, in an improved mechanism by means of which the spool carrying the rope connected with the sand-pump is operated, and upon the same shaft the mechanism for raising the drill may be connected.

In the drawings, Figure 1 is a view, in elevation, of a well-boring machine constructed according to my invention, with certain parts of the frame broken away in order to show the interior of the mechanism. Fig. 2 is a plan view of the same. Fig. 3 is a detached view, showing the mechanism by means of which the drill is raised and lowered. Fig. 4 is a plan view of the main driving-shaft, showin g the pulleys and clutches operated thereon.

In the said drawings, A represents a frame adapted to receive and contain the operative parts of my device. B represents the main shaft, upon which is carried the main drivingwheel B and cam O, both of which are permanently keyed to the main shaft B. Power is communicated to the mechanism for operating the drill, raising and lowering it, 830., by the main driving-wheel B, through the pulley B upon the shaft D. The office of the cam O is to raise the end of the walking-beam E and (No model.)

permit it to drop at each revolution of the shaft. Upon one end of this walking-beam E is placed a small pulley, adapted to bear upon the cam 0. Upon the other end of this walkingbeam is a second pulley, under which the rope connecting the Windlass with the drill passes. This walking-beam is pivoted at or near its center, as shown at F. This pivot or fulcrum F is adapted to be raised or lowered by means of a screw passing through it, and operated by a crank, F, at the top of the frame. This adjustable feature of the fulcrum or pivot upon which the walking-beam turns 1 consider as an exceedingly important feature of my invention, as by its use the depth of the fall of the drill may be regulated. If the fulcrum is raised the drop of the drill will be less; if it is lowered this drop is thereby increased.

Upon the shaft D, I place a spool, G. Upon this spool is wound the rope or chain used in raising or lowering the sand-pump. WVhen not in use the shaft turns independently within it. When it is desired to operate this spool the clutch 9 upon its side (see Fig. 4) is engaged with its counterpart b. The pulley B is also hung loosely upon this shaft D. It receives its motion from the gear-wheel 13. Upon the other side of this pulley B is permanently attached a second clutch, b. This is adapted to en gage with the pin b which latter is driven through the center of the shaft. When the clutch b is engaged with the pin 11 it causes the shaft 1) to turn with the pulley B and carry with it the pulley D, which is permanently attached upon one end of the shaft. Upon the other end of this shaft D is permanently attached the pulley D adapted to engage with the gear-wheel D This large gearwheel, in turn, is permanently attached to the shaft H, upon whichis permanently attached the spool H. To operate this last pulley B with its clutch b and b, I attach the lever I. This lever is pivoted at any suitable point, but preferably to a cross-bar upon the top of the frame, and is attached to the pulley in any suitable manner. By manipulating this lever the spool operating the sand-pump may be set in motion and stopped; so, also, the device for raising the drill. Upon the spool H is wound the rope or chain used in supporting and 0p- ICO crating the drill. It is connected with the drill by passing over the pulley K, under the small pulley E at one end of the walkingbeam, from thence over the pulley K, and from thence to the drill.

The object of the use ofthe two pulleys K and K, in combination with the pulley E is to enable the drill L to be raised or lowered through a space equal to twice that through which the small pulley E traverses at the same time. Upon one side of the frame I attach the rod M. Upon one end of this rod is aworm-gear adapted to engage with a pinion, I). Upon its other end is a crank for operating the same. The office of this rod, with its crank and connection, is to permit the lowering of the drill without the use of other machinery and without stopping its operation. This is done simply by turning the crank, which, in turn, causes the worm-gear to engage the pinion D, which, being permanently attached to the shaft, turns the pinion D which, in turn, operates the large gear-wheel D upon the shaft II, to which is permanently attached the spool H, carrying the rope or chain used in raising and lowering the drill. To the same side of the frame is attached the rod N. This rod at one end is permanently attached to the spring N. This spring N is connected with the wormgear upon the rod M. \Vhen it is desired to lower the drill L faster than can be done by turning the crank M, the worm-gear is disconnected from the pinion D by pushing forward the rod II, which, in turn, operates the spring N, to which is connected the worm-gear. This loosens all braking mechanism between the spool II and the drill L, when the latter will drop by gravity. It can be arrested at any point by releasing the pressure upon the rod N, when the spring N will force the wormgear to engage with the pinion D.

Having thus described the construction of my invention, the operation is as follows: The machine being placed in position at the point desired for drilling the well, the drill L is lowered to place. Power is then applied to the shaft 13, when, at each revolution thereof, the cam O raises one end of the walkingbeam E, when the other end is lowered, carrying with it the pulley E As this is lowered it raises the drill L. If the fall of the drill L at each stroke is not sufficient it may be increased by lowering the walking-beam E by manipulating the screw in the fulcrum F by means of the crank I If, on the other hand, the fall is too great, it may be lessened by raising the fulcrum in the same manner. \Vhen it is desired to lower the drill a short distance, it is done by applying power to the crank M upon the rod M. When it is desired to raise the drill from the well for the purpose of clearing it out, the pinion 13 with its clutch b, is crowded toward the pinion D by means of the lever I, when the clutch Z) engages with the pin b This will set in motion the shaft D, which, through its gearing and a large gear-wheel, Dflwill turn the spool H and raise the drill. If it is now required to operate the sand-pump, the clutch b is engaged with its counterpart 9 upon the spool G. When the sand has been removed from the well, and it is desired again to operate the drill, it may instantly be lowered to the bottom of the shaft by hearing against the spring N, through the rod N, when the worm-gear upon the end of the shaft M becomes disengaged from the pinion I). This releases the spool H, and the drill L drops by gravity to the bottom of the well.

What I claim is- 1. In a well boring and drilling machine, the combination, with a walking-beam, of a Vertical screw-shaft provided with a verticallyadjustablc frame or block, to which the walking-beam is pivoted, substantially as set forth.

2. In a well boring and drilling machine, the combimition, with a vertically adjustable walking-beam, ot a cam arranged to engage with one end of said walking-beam and actuate the same, substantially as set forth.

3. In a well boring and drilling machine, mechanism for feeding the drill, consisting of an endless screw operating upon a pinion, the latter connected by suitable gearing with the spool, substantially as and for the purpose shown.

t. In a well boring and drilling machine, the pinion B provided with clutches, whereby power may be applied to operate the ropespool or the sand-spool, substantially as and for the purpose shown.

5.
