no'rAR-Y DRILL.

Application filed October 21, 1922. Serial No. 596,114.

This invention relates to new and useful improvements in a rotary drill.

One object of the invention is to provide a drill adapted for use in drilling wells, particularly deep wells, and wherein thedrill bit is rotated through the reciprocating movements of an actuating, or driving member. I

Another object of the invention is to providea drill which may be operated through a cable, by means of the ordinary cable tool drilling rig. A further feature of the invention resides in the provision of a drilling device of the character described which may be readily pulled from or let down into the bore as a unit, and which is of simple construction and may be cheaply and easily manufactured and which will be very eifective in use. XVith the above and other objects in View the invention has particular relation to oer-J tain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings,

wherein Figure 1 shows a fragmentary vertical sectional view of the drill.

Figure 2 shows a fragmentary side elevation. i

Figure 3 shows a transverse sectional view taken on the line 33 of Figure 2 and,

Figure 4 shows a transverse sectional View taken on the line 14 of Figure 1.

In the drawings, the numeral 1 designates the drill bit. which may be of any desired construction and form. This bit is attached to thelower end of the tubing 2 whose lower end is outwardly threaded to receive the collar 3, andwhose upper end carries a stufiing box 4. Intermediate the ends'of said tubing there is formed an annular integral rib 5, and within the tubing there is screwed an elongated nut 6 having internal coarse threads- Fitted through the stufiing box 4 there. is an actuating rod 7 whose lower end is provided with coarse threads which intermesh with the threads of the nut 6, The upper end of this rod is preferably square in cross section and is fitted loosely through a correspondingly shaped hole in the nut 8 which is screwed into the barrel 9, and bolted to the rod 7 on opposite sides of the nut 8 are the

collars

10, 10. The barrel 9 is preferably formed of two sections screwed together, as shown in Figure 1, and the lower end of the lower section has an inwardly turned annular flange 11 which closely surrounds the tubing 2, and interposed between this fiange and-the collar 3 there is a coil spring 12. The upper section of the barrel 9 is provided with a plurality of radiating blades as 13 which work through corresponding slots in the barrel. For convenience in construction this upper section may be cut into lengthwise seg-' ments which are held together at their upper and lower endsby means of the cap screws 1{1,-14. The inner edges of the blades 13 are fastened to yokes 15. Each yoke has end bearings which work on the inwardly extending

bolts

16, 16. These bolts are thread--- rod 7 is such that as said rod is elevated and lowered it will impart rotary motion to the nut 6 and the tubing 2, and this motion will 7 be imparted to the bit 1. Said tube and bit are of considerable weight so that as the bit rotates back and forth it will remain on the bottom of the bore and will disintegrate the formation. The blades 13 will hold the barrel against rotation by engaging with the well casing 20, or the other walls of the well bore, but their corners being rounded off they will permit an up and down reciprocating motion of said barrel; v I

When the barrel is dropped it will strike against the resilient seat 12 thus minimizing the shock and preventing the breakage of parts. When it is desired to withdraw the bit from the bore the cable 19 may be pulled upwardly and the flange 11 engages against the collar 5 so that the entire apparatus may be withdrawn from the bore as a unit.

What I claim is:'-

1. A well drilling apparatus including a drill bit, a tubular stem to the lower end of which the bit is attached, a stuffing box carried by said stem, a nut within the stem provided with internal coarse threads, an actuating rod working through said stufling box and threaded through said nut, a reciprocable barrel to which the rod is attached and means for reciprocating the barrel in a well bore, and a yieldable cushion interposed between the barrel and stem.

2. A drilling apparatus including a drill bit, a tubular stem to the lower end of which the'bit'is attached, a nut within the stem provided with internal coarse threads, an actuating rod threaded through said nut, a reciprocable barrel formed of lengthwise sections, end caps securing said sections together, a resilient seat carried by the stem provided to receive the downward stroke of the barrel and yieldingly mounted radiating blades carried by the barrel and passing, through the wall thereofadapted to engage with the walls of the well bore.

3. A well drilling apparatus including a drill bit, a tubular stem to the lower end of I .which the bit is attached, a bearing carried by the stem, an actuating rod working through said bearing, said stem and rod carrying intermeshing coarse threads, a reciprocable barrel to which the rod is attached, means for reciprocating the barrel in the well bore and means preventing the independent rotation of said rod relative to said barrel.

4. A well drilling apparatus including a drill bit, a tubular stem to the lower end of which the bit is attached, a bearing carried by said stem, an actuating rod working through said bearing within said stem, said rod and stem being provided with coarse intermeshing threadsfa reciprocable barrel to which the rod is attached, means for reciprocating the barrel in the well bore, means for preventing the independent rotation of said rod relative to the barrel and means for anchoring the barrel against rotation relative the walls of said bore.

In testimony whereof I have signed my name to this specification.
