Application led October 86, 1925. Serial lo. 84,851.

This invention relates to new and useful imrovements in a whip stock.

ne object of the invention is to provide Va whip stock formed of sections hinged to-v gether.

In drilling wells it often becomes necessary to side track, that is to cut through the side of the casing in the bore and continue on down in a new hole. In order to do this it is common practice to drop a whip stock down into the bore, which forms a deflecting guide for a milling cutter used to cut laterally through the casing.

The type of whip stock commonly used consists of a cylindrical body whose upper end is beveled off on a long taper, said tapering end forming a wedge like deflector for the milling cutter which lateraly against the casing to be perforated, and as said cutter is rotated and moves downwardly it will cut a long vertical hole through the casing through which the drilling tool may work in the formation of a new bore.

In case the casing is crooked it often ha pens that the upper beveled end of the'ort'inary whip stock will stand out from the casing and will not give room enough for the cutter to wedge in between it and the casing. The whip stock herein described is formed of sections hinged together so that the upper end thereof may lie back closely alongslde the casing irrespective of the contour of said casing in the bore. f

With the above and other ob'ects in view this invention has particular relation to certain 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 l shows a fragmentary side View of the whip stock as located in a casing.

Figure 2 sho-ws a side view of the lower end of the whip stock located in the casing.

Figure 3 shows a fragmentary front elevation of the whip stock, and

Figure 4 shows a cross sectional View taken on the line 4-4 of Figure 3.

In the drawings the numeral 1 designates a casing set in a well bore. Sometimes the bottom of the boreVis obstructed by the droppip of a bit, or tool, therein, or otherwise so t at drilling in the old bore cannot be continued and an opening must be cut through rest on the bottom of the bore.

forces said cutter.

closely against t e the side of the casing and drilling continued through said opening and anew bore thereby contlnued on down. In order to side track as above explained, a whip stock is dropped down into the casing and a milling cutter employed to so perforate the casing. As shown the whip stock includes a cylindrical body 2 whose lower end may be arpened, as at 3, formin a guide and this lower end will wedge in te upper end of a lower reduced section, as 4, of the casing, or The upper end of the whip stock is beveled one way on a long taper forming a slopin face as 5.

Th1s face may be provide with an upwardly inclined recess 6 to receive a hook on the lower end of a cable by means of which the whip stock is let down into the casing. Ordinarily the back side of the whip stock, op ite the face 5, will lie casing wall, particularl if the casing is straight. If the casing 1s crooked it often happens that the up er end of a one piece whip stock will stand away from the casing wall so that the milling tool 7 will ride on the said upper end. In the present form the upper end of the whip stock is hinged to the main bod the axls of the hinge 8 bein substantial y parallel with the planel of t e face 5. This hinge will permit said upper end to lie back closely against the casing wall irrespective of the course of the casing.

What I claim is 1. A whip stock having a beveled upper end hinged to the main body thereof.

2. A whip stock formed of a plurality of sections hinged together.

3. A whip stock having a bod upper'end is beveled'on one side an jointed.

4. A whip stock formed of an upper section and a. lower section, said sections being jointed to ether, the'u per section havin a face inc ined to the lbngitudinal axis o the whip stock. i

5. A whip stock formed with a lower cywhose lindrical section and an upper section hinged 'to the lower section the u per end of the whip stock being beveled orming a lateral face inclined to thelongitudinal axis of the whip stock. l

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