Description

3 forms a support for the wedge as clearly shown in Figs. 1 and 2 of the drawings. The lower section 2| of the body I2 is threaded at 26 to receive the coupling III by which the body is joined to the tubing section I I.
The means 22 joining or coupling the body sections 20 and 2I is preferably a threaded connecting means and in the case illustrated it involves an internally threaded sleeve portion 3D on one body section and a pin portion .3| on the other body section, which pin portion is threaded into the sleeve. In the preferred arrangement the sleeve 33 is in the nature of an enlargement on the upper end portion of the lower body section 2I `while the pin portion 3| is formed by merely threading the lower end portion of the body section 20.
The wedge I is a sleeve-like member surrounding and carried by the upper body section 2U 'and in a-ccordance with my invention the upper end portion of the wedge is bored at 35 to receive the upper end portion 35 of body section 20 occurring above the wedge seat 25. The wedge I5 is counterbored at 3l from its lower end to receive the seat portion 24 of body section 20. Between the bores 35 and 3'I there is a downwardly facing shoulder 38 which engages and rests upon the upper upwardly facing shoulder 25 on body section 20. The wedge I5 is yarranged in position on the body section 20 by being slid over the threaded end portion 23 vand when in place with the shoulders 25 and 38 in engagement the collar or coupling I3 is -applied to the threaded portion 23 to form a retainer holding the wedge in place on the body section 2B. Through this -construction the body section 20 is apart simple and inexpensive of manufacture and likewise the wedge I5 is a simple sleeve-like part simple of manufacture.
The exterior of the wedge I5 is provided with a plurality of downwardly and inwardly extending Wedge faces 39 on which the slips I6 are carried. In practice the number and arrangement of slip faces 39 may be Varied. However, ordinarily it is desirable to provide three slip faces equally spaced around the wedge as illustrated in Fig. 3 of the drawings.
Slips I5 may be simple, conventional gripping devices or slips such as are common to oil well tools in which case they have inner faces 40 slidably carried on the wedge faces 39 and they have outer gripping faces 4I that may be toothed or otherwise finished to have the desired gripping action. In the preferred form of the invention the slips are joined to and are guided on the wedge by means of dove-tailed guides 42 which extend lengthwise of the tool.
The hydraulic operating means I'I that I have provided includes, generally,`a cylindrical barrel 55 which surrounds and works over a substantial portion of the body I2, that is, over the lower end portion of the body section 20 and the upper end portion of body section 2l. A head 5I closes the upper end of barrel 5U and is slidably engaged on the lower end portion 52 of body section 28. A headV 53 closes the'lower end of the barrel 5U and is slidably carried on the body section 2 I. In `accordance with my construction the head 5I is fixed to or may be integral with the barrel 50 as shown in the drawings, whereas the head 53 is detachably connected to the barrel as by a threaded connection, with the result that in assembly'the head 5I is slid onto the lower end portion 52 of body section 2U whereupon Abody section 2I `is -coupled withbodysection .20 through tubing section II.
the connecting means 22 after which the head 53 is slid over the lower end of body section 2I `and is threaded to the barrel 50. An enlargement or' flange is provided on the body I2 between the'f heads 5I and 53, preferably on the sleeve '35 of means 22 to form piston part 60 which slidably ts the interior of barrel 55. In accordance with my invention a sealing means or ring 6I is carried by the head 5I to provide sealing engagement between the head 5I and portion 52 of body section 20 and packing, or a packing ring, 62 is carried by the piston 60 to seal between the piston 60 and the interior of the barrel 50, dividing the barrel into upper and lower chambers 63 and 164, respectively. l
The reaction spring I8 is a helical compression spring and is carried on the body portion 2| between'the piston 60 and the head 53 to normally, yieldingly urge the barrel 5E downwardly relative to the body. The downward movement of the barrel is stopped through engagement -of the head 53 with the upper end of the coupling i4 by which the body is co-upled to the In accordance with my invention one or more ports 'I0 are provided in the portion 52 of body section 2U preferably just above the means 22, whichy ports connect the interior of the body with the chamber 63 at the upper end of barrel 5I). Through the ports I0 fluid introduced into the tubing T or into the body of the anchor passes through the ports into the chamber 63 and when the pressure of such uid is sufficient the barrel 56 is forced upwardly relative to the body I?. against the action of the spring 65.
I provide coupling means between the barrel 55 and the slips preferably in the form of links 'I5 coupled to the barrel by pivot pins I5 and to the slips by pivot pins TI.
With the construction that I have provided the anchor secured to or in the tubing T, as shown in the drawings, is lowered into the casing C to the desired position, whereupon fluid pressure is established in the tubing sorthat fluid passes through the ports 'I3 and into the chamber 63 to force the barrel 50 upwardly. As the barrel is moved upwardly relative to the body I2 the slips are moved upwardly on the wedge I5 and through the tapered engagement between wedge and slips the slips are moved outwardly into gripping engagement with the casing. The wedge engagement of the slips with the casing provides a positive check against downward movement of the tubing and so long as a head of fluid is maintained in the tubing the slips are held up on the Wedge and in gripping engagement with the casing. Atr any time that it is necessary to withdraw the tubing it is merely necessary to pull it upwardly in order to lift or tend to lift the wedge out of the slips and thus release or relieve the gripping action of the slips so that the tubing can be moved up in the casing. During insertion of the anchor into the casing the spring I8 maintains the barrel in the down or retracted position.
rThrough the construction that I have provided the parts may be fitted and related so that the tubing T can be turned relative to the anchor if such action is desired. It will be apparent that the parts can be assembled so that the body section 25 can turn within the wedge i5 and the body section is free to turn within the barrel 50, with the result that the wedge I5 and slips may remain set while the tubing T is turned in either direction relative to the seat parts. So-long. as a head of fluid is maintained in the tubing the barrel 50 is urged upwardly relative to the body I2 or it may be considered that the body l2 is urged downwardly relative to the barrel to the end that whichever part or element is free to move or can be shifted does move relative to the other part with consequent gripping action, which serves to electively anchor the tubing in the casing.
Having described only a typical preferred form and application of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in the art and fall within the scope of the following claims.
