Dec. 8, 1931. c. H. LANE ET AL WHIP STOCK Filed Aug. 5, 1929 Patented Dec. 8, 1931 UNITED STATES PATENT OFF-ICE cnAnLEs :1. LANE AND cmins H. nuv notns, or nousro m rms WHIP sroex Application filed August 5, 1929. Serial m. ssasas. a

This inventionrelates to-new and useful imgrovements in a whip stock.

ne object of the invention is to provide a whip stock of the character described with novel means, operable by fluid pressure, and effective toanchor the whip stock. against downward movement in, and against rotative movement relative to, a pipe ina well bore in which the whip stock is located.

In drilling a well, a casing is often 'set in the well bore and it sometimes becomes necessary to perforate the side of the c'asin to form an opening through which the tool may pass in order to side track the lower end of the original bore. In the work of perforating the casing a whip stock is located in the casing having a sloping face-and -a milling tool is then let down into the casing and is forced by said sloping face against the side of the casing to be perforated and this milling tool eventually cuts through'and perforates said casing to provide an openin through which the drilling tool and the dr' stem driving the same, may work.

It has been a common practice to attach the whip stock to the upper end of a string of pipe of the desired length and then-to lower this assembly into the bore with said string of pipe resting on the bottom of thebore and serving to support the whip stock at the .de-

sired place in the casing. However when a whip stock is so set it is liable to turn or revolve about in the casing and thus seriously interfere with the work of milling through the casing. It is the prime object of this be readily located at any desired place in the casing and'then securely anchored against rotative movement in the casing.

With the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of trated in the accompanying drawings where- Figure 1 shows a side elevation of a whip stock anchored in a casing and shown partly in the casing, and.

Figure 2 shows a transverse sectional View g contour thus in, and the bottom of eachinvention to provide a whip stock that may which is given in this specification and illusforming a channel-13' which forms a part thereof taken on the line 2'-2 of Figure 1.

f Referring now more particularly to the to the upper end of the whip stock. Beneath the cylindrical body 1 thewhip stock is reduced forming a downwardly tapering mandrel 3 preferably triangular in cross sectional presenting the flat downwardly converging faces 4:. These faces havethe vertical dovetailed grooves or guides 5 there- 7 oove is formed with the upwardly pitched ratchet teeth as 6. Slidable on the faces fare the respective slip jaws 7 which have dovetailed tenon 8 which move in the corresponding grooves 5. These itenons have the downwardly pitched ratchet teeth 9 adapted to cooperate with and engage the corresponding teeth 6. a Attached to the lower end of the mandrel there is a c linder 10 in which there is a piston 11. (gonnecting rods 12 are provided 7 whose lower ends rest on the piston ll-and their upper ends may rest against, or be pivoted to, the corresponding slip jaws 7.7 These connecting rods work through upwardly diverging bearings provided in the cylinder 10 and in the lower end of the mandrel 3a1'1d may be made sectional if desired, so that they may be more readily inserted into said hearings, in assembling them. There is an axial channel 13 leading down through the whip stock proper'and through the'man- I drel and wall of the cylinder and whose lower end enters said cylinder beneath the piston.'

The cylinder 10, as shown, is screwed onto the reduced lower end of the mandrel 3 and these connected parts have annular. grooves which register, when'the parts are screwed together screwing the cylinder on the mandrel. Above said piston the cylinder hasan inlet port 14.

The upper end of the channel 13 is enlarged and provided with left hand threads 15.

In operation the whip stock may be assembled as shown and attached to the lower end of a drill stem or other string of pipe, said lower end of said string having left hand threads which are screwed into the upper end of the channel 13.

When the device is let down into the casing 16 in the bore to the desired place, fluid under pressure may then be forced down through said string and through the channel 13 into the cylinder 10 beneath the piston 11 and said piston will be thereby forced upwardly forcing the slip jaws 7 upwardly and outwardly along the faces 4 into engagement with the casing and the teeth 6, 9 will inter'engage to maintain said slip jaws in vsuch engaging position. It is tobe noted that two of said jaws have external circumferential teeth which will serve to engage the casing and anchor the whip stock against downward movement and another of said slip jaws has external vertical teeth which will engage the casing to holdthe whip stock against rotative movement.

When the whip stock is set the setting stem or string may be detached from it by turning said string to the right and then withdrawn and a milling tool attached to the lower end of an operating string may then be let down into the casing and rotated and said tool will be deflected by the face 2 against the opposing side of the casing toibe perforatedand said milling tool will thereby cut the re; quired opening through the side of the casing 16 through which drilling operatlons maybe thereafter carried on.

A preferred form of the invention has been disclosed inthe drawings and specifications by wa of illustration only-while the broad principle of the invention will be-de.

I fined by the appended claims. j
