BAILER DUMP.

Application filed May 12,

This invention relates to means used in carrying out drilling operations in the sinking of deep oil wells.

The principal object of the present invention is to produce an eliicient and ett'ectual means in the form of a combined bailer and dump with which liquid bailing and dumping operations may be optionally carried out.

Another object is the provision of a bailer dump having a device of simple construction associated with the valve dart which serves for carrying out liquid dumping operations, and which is detachable so that liquid bailing operations may be carried out.

With the foregoing and other objects in view the invention resides in the particular provision, relative arrangement. and construction of the parts hereinafter fully de scribed and illustrated.

The nature of the invention and its distinguishing features and advantages will appear when the following specification is read in connection with the accoi'npanying draw ing, in which Figure 1 is a sectional elevation of the bailer dump of the present invention being lowered in an open well hole.

Fig. 2 is a fragmentary sectional elevation, the valve dart being viewed from a point different from which it is viewed in Fig. 1.

Fig. 3 is a view similar to Fig. 1, but showing the valve dart held ofl of its seat by the device connected thereto.

Fig. 4.- is a transverse sectional view taken on the line 4-4 of Fig. 3.

Fig. 5 is a perspective view of the valve chart and holding device connected thereto.

In carrying out drilling operations in sinlc ing deep holes. it is necessary at times to bail out water or oil in the hole, and it is also necessary at times to deposit or dump quantities of water into the hole to facilitate the operation of the drilling. This bailing or dumping of liquid must be done when drilling operations are being carried out in an open hole in a manner to keep the walls dry and therefore from being); washed down, which would clog; up the hole and interfere with the sinking of diticrent tools in casings. and otherwise impede the work.

In accordance with the present invention an ordinary type of bailer. such as the one designated 10 is equipped with a holding: device 11. The device 11 is detachable and 1926. Serial N0. 108,626.

functions for converting an ordinary bailer to a dump for dun'iping liquids. The bailer 10 in the present instance includes a shell or bucket 12- having the usual bail 13, at the upper end and an annular member 14 at the lower end thereof attached to the shell 12 in any suitable manner, and having a seat 15. The bailer also includes a valve dart 16 of ordinary construction which coacts with the seat 15. The valve dart 16, in tact gravitates to the seat 15 on which it normally rests to hold a quantity of liquid placed in the shell 12. The member 17 of the valve dart 16 ertcnds below the member 14 a considerable distance. and is widened out to provide shoulders 18 which prevent the valve dart from being pushed all of the way in the end of the shell 12. In order to releasably maintain the valve dart oil? the seat with which it coacts so that a quantity of liquid .in the shell 19. may be dumped theretronr there is provided a means which will consist of portions of the member 14 and a device 19 which coacts with the portions of the member 14. The device 19 is carried by the member 17 of the dart and in the present instance the device 19 consists ot flexible members 20 each of which is similar in construction, and each of which is bent and formed to provide an attaching portion 21., a. bowed or arched portion 22. and a portion 23 which engages the member 17 when the flexible member 20 is in place to set up the proper amount of frictional contact. The members 20 are attached by virtue of the employment of a bolt or the like 24 which extends through the lower end of the member 17 and also through the portions 21 respectively of the member 20. In this way the members 20 are detachably supported on the valve dart itself. It will now be apparent that when it is desired to dump a quantity of liquid in the bottom of the open hole the bailer dump of the present invention is lowered into the hole until the lower end of the member 17 engages the bottom Upon the further lowering of the shell 1.2, and under its weight the member 14 will be brought in surrounding relationship with respect to the bowed portions 22 ot the members 20, and as a result frictional engagement of the portions 22 and portions of the member 14 will be set up. This condition is illustrated in Fig; 3 in which the valve dart is held ofi the seat 15. It will now be understood that when the shell 12 is elevated the dart will he carried with it. but in the position in which it is held ofii' the seat 15 so that all of the liquid may run out of the lower end of the shell 12. To convert the dump type of bailer to an ordinary bailer, it is only necessary to detach the members 20 as will he understood.

I claim:

In a hailer dump, a shelh a tubular member fitting within and secured to the lower extremity of said shell, said tubular member having a smooth inside said tubular member providing a seat, a valve dart having a depending extension with a hole in the lower end thereof, said alve dart adapted to rest on said seat when the valve dart is in its normal position to close the lower end of the shell, a pair of flexible members,

tional contact of the bowed portions with the inside ot' the tubular member, when the valve dart is moved upwardly with respect to the shell. to releasahly hold the valve dart otl' the seat, to open the lower end of the shell.
