WELL-DRILLING APPARATUS.

Application filed. November 29, 1915.

To all whom it may concern:

Be it known that I, ALLEN G. German, a citizen of the United States residing at Crookston, in the county of Folk and State of Minnesota, have invented certain new and useful Improvements inWell-Drilling Apparatus, of which the following is a specification. i

The present invention relates to well boring or drilling apparatus, and is especially designed with a view to providing what I term a complete combined jetting and solid tool machine. To this end it has been my aim to so arrange the several instrumentalities required for boring wells by either the jetting or solid tool processes in such a compact and cooperative manner as to facilitate the accomplishment of the result irrespective of which process is found best to employ.

It is to be understood that the essence of the invention lies in the detail features by means of which the drill or bucket ropes are operated or controlled and "the stroke of the member for actuating the drill rope and the boring tools connected thereto may be regulated.

For a full understanding of the present invention, reference is to be had to the following description and the accompanylng drawings, in which:

Figure 1 is a side elevation of an apparatus forming the embodiment of my invention. Fig. 2 is a top plan view of said device. Fig. 3 is a longitudinal sectional view on the line 3-3 of Fig. 2. Fig. 4 is a transverse sectional view on the line 49-4 of Fig. 2. Fig. 5 is adetail elevation of the brake control for the drill rope winding drum. Fig; 6 is a longitudinal sectional view on the line 66 of Fig. 2. Fig. 7 is an enlarged sectional view of the cam member for operating the oscillating beam. Fig. 8 is a vertical sectional view on the line 8-8 of Fig. 3. Fig. 9 is a vertical sectional view on the line 9--9 of Fig. 1.

Throughout the following detail description and on the several. figures of the drawings, similar parts are referred to by like reference characters.

Referring to the drawing and specifically describing this'apparatus, the numeral 1 designates a frame'of suitable material supported upon the ground wheels 2 and having at its forward portion an auxiliary frame 3. At the forward end of the ma- Specification of Letters Patent.

chine is arranged the stub derrick 4 upon which the main derrick 5 is pivotally mounted as at 6. r The derrick as in customary structures of this character is designed to be held in vertical position normally by locking means such as the catch 7, when the drilling operation is being performed. Under other conditions, however, such as removal of the apparatus from place to place,

passes around a sprocket 13 loosely mounted upon the driving shaft 14 arranged transversely of the frame 1 at an intermediate portion thereof. The chain 12, furthermore, passes beneath an idler or tightening wheel 15 carried by a transversely arranged shaft 16 mounted upon the rear extremity of the auxiliary frame 3 in rear of the winding drum 9.

The driving shaft 14 has mounted thereupon a large fly wheel or belt pulley 17 which is operatively connected by the belt 18 to the engine shaft 19 of the engine 20. Said engine may be of any desired type but in the illustration is an internal combustion engine of suflicient power for carrying out the functions of this invention. One of the advantages of the apparatus is that the power of the engine may be comparatively small and yet perform the service adequately.

The drill rope 10, it will be understood, is of sufficient length to'enable it to reach to the bottom of the well which is to be bored and said rope passes from the drum around the guide sheave 21 carried at an interme- .diate point of the shaft 16 just in rear of the winding drum 9, the. rope passing then around a sheave 22 carried by a block 23 adjustably mounted upon the forward portion of the actuating member of beam 24. The forward end of said beam is slotted longitudinally, as indicated at 25 to permit the positioning or adjustment of the block 23 toward or from the forward extremity of this. -Mai i Willb b a h 19" 1 scription proceeds, that the adjustment of this block, whereby the rope is operatively connected to the beam to enable drilling movement to be imparted to the drill rope 10, will control the length of stroke of the tool connected to the extremity of said rope. The beam 24 is pivoted slightly to one side of its center upon the axis 26 and its rear extremity lies adjacent to one side of the driving pulley 17 hereinbefore mentioned.

to perform their drilling function. During the drillingoperation, it will be understood that the drill ,ro'pe drum 9 will be held from movement by means Which will be described more clearly hereinafter. One of the particularly advantageous features of my construction is the disposition of the guide sheave 21 in spaced relation to the beam '24 for the purpose of relievingthe beam of side stress during winding of the rope upon the drum andvery materially reducing the friction upon said beam which is usually .presentwhere such guide sheave is connected to the beam itself in the conventional drilling structures.

Referring particularly to Fig. 5 of the drawing, the numeral 30 designates the head of the winding drum 9 opposite to the head 11 and this head is utilized as a combined head and brake element for controlling the rotation of the drum 9. At one end a brake strap or band 31 is connected at 32 to the frame 3 and at its other end is connected to an intermediate point of the dog 33 pivotally mounted upon the main frame 1 at 34. A lever 35 is connected to the dog 33 by the link 36 and said dog 33 is designed to cooperate with a ratchet wheel 37 attached to one side of the head 30. Under normal conditions therefore, as when the drill rope is being actuated by the beam 24 the dog 33 holds the drum 9 from movement by engage ment with the ratchet 37, but when it is desired to lowerfthe drilling tools into the well, the lever 35 is moved rearwardly thereby disengaging the dog and bringing the brake strap 31 into coaction with the head 30 so that the descent of the tool is very easily controlled. Movement of the lever 35 intoan intermediate position obviously will enable the free rotation of the drum in either direction according to whether it is actuated by the engine or by reason of the gravitation ot the tool, as the. case may be.

hen it is desired to withdraw the tools from the well the clutch member 38 mounted upon the driving shaft 14 is engaged with the sprocket 13 suitably formed for this purpose by means of the lever 39 extending to the rear extremity of the frame 1 and connected to said clutch member 38 by the bell crank 40. The driving shaft 14 through the belt 12 will cause rotation to be imparted to the winding drum 9 and the rope will thereupon be wound upon said drum. The drum, furthermore, is susceptible of being manually operated by means of a crank 41 attached to one end thereof as shown in Fig. 2 of the drawings.

Another of the special features of my apparatus is the control of the actuation of the rocker beam 24 by stop means which limits its rocking movement. For this purpose I provide upon the frame 3 an adjustable stop member 42 with which the end of the beam 24 is adapted to impinge when released by the cam 27 on the belt pulley 17. The stop means is adjustable by a handwheel 43 so as to project downwardly a greater or less degree and, therefore, limit the pivotal swinging movement of the beam accordingly. The end of the beam is preferably provided with a cushion 44 of any desired type.

As hereinbefore premised, the apparatus is designed to be used as a jetting machine, and, therefore, I provide at one side of the frame, the pump 45 having diametrically opposed plungers 46, 47. From this pump the jetting conduits 48 lead to thewell which is being drilled and the operation of the pump is carried out by means of the connection of the guide rods 48 to said plungers for simultaneous movement in opposite directions and through the pitman rod 49 to the crank wheel 50 loosely mounted on one end of the driving shaft 14. As shown in Fig. 9, the crank rod is adjustably connected to the crank wheel 50 so as to adequately control the operation of the pump as found necessary, and this connection is a detachable one so that when it is not desired to utilize the jetting instrumentalities, the pitman 49 may be disconnected from the crank wheel, as when utilizing solid tool implements. To connect the pump mechanism for operation, the clutch member 51 is engaged with the crank wheel 50 by the lever 52.

The wheel 50 is a combined sprocket and crank wheel and carries a chain 53 which passes around a sprocket 54 loosely mounted upon the shaft 55 journaled in the braces 56 at the forward portion of the drilling apparatus. On this shaft 55 is mounted a bucket rope drum 57 adapted to be actuated from the engine and the driving shaft 14 by clutching the sprocket 54 with said drum through the instrumentality of the lever 58 rnounted upon the forward portion of the drilling apparatus. The bucket rope drum 57 has wound thereupon the bucket rope 59 which passes over a sheave 60 upon the upper end of the derrick 5 adjacent to a corresponding sheave 61 over which thedrill rope 10 passes.

It follows from the foregoing description that when not utilized as a jetting machine and using the solid tools and slush bucket in the customary manner the pitman rod 459 of the pump mechanism is disconnected from the crank wheel 50 and the clutch member 51 is engaged as well as the clutch connection operated by the lever 58 to run the bucket rope drum 57 for drawing the slush from the well. At the end of the driving shaft 14 is mounted a half spool or winding drum 62 and this may be utilized for withdrawing the tools when the jetting instru mentalities are employed, a rope running from the tools being connected to this spool in the manner well known to those skilled in the art to which the invention refers, during driving of the driving shaft by the engine.

It will be apparent from the foregoing description that the present apparatus is de signed to facilitate the operation of drilling wells either by one or the other of the processes hereinbefore mentioned and it will be understood that slight changes in the arrangement and construction, of parts may readily be made without departing from the spirit of the invention and within the scope of the appended claims.

Having thus described the invention, what is claimed is:

1. In a well drilling apparatus of the class described, the combination of a frame, a

'revoluble means for adjusting said drill rope, a beam carried by said frame and pivoted intermediate its length for vertical swinging movement, means connectlng said rope to the beam at one end thereof, revoing action to the rope aforesaid, and a manually operable stop mounted on the frame above the end of the beam carrying the rope connecting means for controlling movement of the said end at will.

2. In a well drilling apparatus of the class described, the combination of a frame, a drill rope, an oscillating member mounted on said frame and to which the rope is connected, adjustable stop means on the frame for controlling the stroke of said oscillating member, and operating means for adjusting the stop means whereby to regulate the stroke at will.
