Application filed June 8, 1906. Serial No. 320,874.

To all whom it may concern:

Be it known that we, JOHN R. GRIFFITH and LESLIE G. GosrEn, citizens of the United States, residing at Independence, in the county of Montgomery and State of Kansas, have invented a new and useful Well-Drilling Machine, of which the following is a specification.

This invention relates to well drilling apparatus; and it has particular reference to that class of drilling machines which are mounted upon suitable running gear so as to be capable of being conveniently trans ported from one place to another.

One of the principal objects of the present inven tion is to provide a machine of novel and improved construction which may be used interchangeably for operating drilling mechanism through the medium of a walking beam, or by spudding mechanism, or whereby, when desired, a rotary drill may be operated; means being likewise provided for operating the sand pump, and likewise for hoisting or otherwise manipulating the well casing by means which are independent of the drilling mechanism, so that the drill rope does not require to be rethreaded or rearranged when the casing is to be manipulated.

Further objects of the invention are to simplify and improve the general construction and operation of the machine.

With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the invention may be made, when desired.

In the drawings, Figure 1 is a side elevation of a drilling machine constructed in accordance with the principles of the invention. Fig. 2 is a top plan view of the same. Fig. 3 is a vertical transverse sectional view taken on the plane indicated by the line 3-3 in Fig. 2 through the main shaft of the machine. Fig. 4 is a detail view, in elevation, of a portion of the main band wheel., Fig. 5 is a perspective view of the clutch betweeuthe main shaft and bull wheel, the members of the clutch being shown disassembled.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

The frame F of the improved machine is supported upon running gear including the front and hind wheels 1, 2. The main shaft 3, which is supported for rotation in suitable bearings upon the side members of the frame, carries the drum or reel 4 having at one end thebull wheel 5 and at the other end a flange G, the latter being bolted or otherwise suitably secured upon a collar '7 which is formed upon the body of the drum. The latter is provided at the opposite end with a collar 8 and with an annular loose ring or flange 9 between which the bull wheel 10 is secured, as by means of clamping bolts 1]. At the ends of the drum are recesses, as 12, affording seats for an lifricrion rollers 13 which are retained in position by means of collars 14.

One end of the drum 4 which extends beyond the bull wheel 10 has a clutch member 15 adapted to cooperate with a clutch member 16 formed upon a hub 17 that is keyed upon and in slidable engagement with the main shalt 3; said hub carrying also a sprocket wheel 18. The hub 17 has an annular groove 19 engaged by a shipping lever 20 which is under the control of the operator who, at will, may engage the clutch members 16 and 15 to thereby lock the drum 4- upon the shaft 3 for rotation with the latter.

The main shaft 3 carries at one end, which extends beyond one side of the frame, a belt wheel or band wheel 21. which is clamped between hub members or flanges 22 and 23 that are bolted together through the body of the band wheel, which latter is secured upon the shaft by means of a key or spline 24f engaging the hub members. The outer hub member 23 is made up of two segments connected with each other by transverse clamping bolts 25 whereby the key or spline 24 is clamped very securely in position. By loosening the bolts 25, the key or spline 24 may be withdrawn and the band wheel may then be removed from the main shaft; this being a matter of great convenience when a machine is tobe transported from one place to another, especially over rough or mountainous roads. "he opposite end of the main shaft 3 carries a crank 26 having a wrist pin 27 adapted to be connected by means of a pitman 28 with the walking beam 29 which is supported upon the Samson post 30, the latter being preferably com rosed of two beams converging upwardly in approximate A-shape, so to provide an extended bearing surface and thereby relieving the frame of the machine from ulniecessary strain.

A flexible brake band 3]. encircles the bull wheel; one end of said brake band being connected in the usual manner with a crank 32, which is connected by a link 33 with another crank 34. capable of being manipulated by a lever 35 at the front end of the machine, where it may be conveniently controlled by the operator.

A shaft 36 is supported in suitable bearings, parallel to the shaft 3, and is driven therefrom by the sprocket l8, link belt 41 and sprocket 40, said shaft 36 carrying a clutch member 37 which is splincd on the same, so as to be slidable thereon and rotatable therewith; said clutch member being controlled by the operator by means of a shipping lever 38. The clutch member is l which one end of the sand reel shaft is journaled, is

adapted for engagement with a drum 42 which is rotatable upon the shaft 36 and which carries at one end a brake wheel 43 clamped between the flanges 14 and 45 and encircled by a brake band 46, one end of which is connected with a crank 47 operable by a lever 48. The shaft 36 carries at one end a sprocket wheel 49 adapted to be connected by a link belt 50 with so-called rotary apparatus constituting a rotary drilling outfit at the well opening to which power may be in this manner transmitted, when desired. The shaft 36 carries at its opposite end a crank 51 having a wrist pin 52 upon which a spudding wheel 53 is mounted for rotation; the said spudding wheel being in alinement with a guide pulley 54 that is suitably supported upon the frame of the machine for the purpose of guiding the rope to the spudding wheel from the drum 4:, and preventing injury to the rope by frictional contact with the frame of the machine.

The drum 42 upon the shaft 36 is adapted to carry a flexible element'for raising and lowering the casing, which operation may thus be performed independently of the drill rope, which in practice is wound upon the drum 4. A separate drum and hoisting element for manipulating the casing is always a valuable acquisition either to a standard rig or a drilling machine, and it is an absolute necessity when a rotary drilling outfit; is used.

A shaft 55 supported for rotation in bearings in rear of the main shaft 3 carries the sand reel 56, and said shalt also carries a friction pulley 57 adapted for engagement with the band wheel 21 to be thereby driven. One of the bearings of the shaft 55 is in a lever 58, whereby the shaft may be slightly rocked, as required, to place the friction pulley 57 into or out of engagement with the face of the band wheel; the lever 58 being connected by a link rod 59 with an operating lever 60 at the front end of the machine.

The band wheel 2]. may be driven from any suitable source of power; when the machine is a large one, an independent motor will preferably be provided; if the machine, however, is not of great size, a motor, as M, may be supported upon the frame F; the main shaft (31 of such motor being provided with a pulley (32 adapted to be connected with the band wheel 21 by means of a driving belt or band.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. The main shaft 3 may be operated independently of the drum 4, but the latter may be locked securely upon the main shaft by means of the clutch upon the hub 17. Motion is transmitted from the hub 17 and the sprocket wheel 18 upon the latter to the sprocket wheel 40, which rotates the shaft 36. By placing the clutch 37 in engagement with the hub of the drum 42, motion is transmitted to the latter.

The entire mechanism of the improved machine is simple in construction and may be readily controlled by the operator who is stationed at the front end of the machine within convenient reach of the lovers whereby the parts of the mechanism are controlled.

The operating lever 58, which provides the bearing in preferably composed of two separate parts or members 58 spaced apart by one or more thin washer plates, as 59; the members 58 being connected together on opposite sides of the plates by bolts 60, one of which is an eye bolt that serves to form a connection with the link rod 55). lly this construction, wear of the sand reel shaft in its bearing may be compensated for by occasionally removing one of the washer plates, thus enabling the members 58 composed of the lever to be moved together so as to reduce the size of the aperture that constitutes the bearing for the sand reel shaft.
