Sept. 21, 1948. J. J. SANTIAGO BAILER UNLOADING RACK Filed Sept. 4, 1945 J4ME5 J SANWA 6O 1 N VEN TOR ATTORNEY v Patented Sept. 21, 1948 ago, has Ange es, 'dalit, assi -.t-o .Grant -il;='l;ool; Company; Los 1 .acorporatiomof California an l er al t lbpplication septernber 4, I-MS'QS-eriaI-NO;14355 i k This invention has for its general object to facilitate the discharge-pr dumping of fluid charges .from well bailers, in the: operation of which the charge is taken into a bailer lowered to the bottom of the well, and is dumped by manipulation of the bailer' parts after-"removal to the ground surface. More particularly-the invention relates stOfiZ. novel: bailer support nor ,qcradle :adaptecl ltowreloeive or support a type of bailer; havinggpajrts :relsativelyiir ovable to dump the charge, thevfuncgtion ofthe supporter cradlenbein to hold one .such bailenpart against movement duringathe fluid dumping manipulation of-the otherrpart.

, dis illustrative, the invention .will be described with reference to a crad1e;type..support-adapted to receive a bailer of the type and construction shown in my co-pending application Ser. No. 540,782, filed June 17, 1944, on Hydrostatic bailer, now abandoned. That type of bailer comprises a combination of parts or sections, one of Which is rotatable relative to the other to dump the charge through an opening in the side of the bailer. One particular object of the invention is to adapt the supporting cradle for engagement with one of the bailer sections to hold the latter against rotation during rotative movement of the other section in the charge dumping operation.

In accordance with the invention, I have provided a bailer support which most desirably has the form of a cradle capable of supporting the bailer in an upright position, but preferably at a suitable inclination. Incorporated in the cradle structure is a holding means for restraining rotation of the engaging portion of the bailer. In the hereinafter described specific form adapted for cooperation with the type of bailer disclosed in my said co-pending application, such holding means may consist of a simple shoulder arrangement engageable against flattened surfaces on the bailer to arrest rotation, and adapted also to vertically support the bailer.

The various features and objects of the invention, as well as the details of a typical and preferred form, will be understood to better advantage from the following description of the accom panying drawing, in which:

Fig. 1 is a perspective view showing the bailer support;

Fig. 2 is a fragmentary sectional view illustrating a typical form of bailer inserted in the support; and

Fig. 3 is a cross-section on line 33 of Fig. 2.

Referring first to Fig. 1, the support, generally indicated at l0, may have any suitable base or means for attachment to the derrick floor for ,e lolaan (01. 166-19) thenurnose ofase uring the support in:n1a e.,.As

illustrativegthe structure .-is shown to cor -prise aobase all .having; holes .12 .tor t e :reception of anchor screws t-or .bolts. Extending vertically .abovethe .base-isga suitable cradle support, show-n typically as a pipe column! 3 ofsuificient. height to accommodate the lowerportion ofthe supported bailer above .thefloor *or base. .A cradle .l4,--ope,n at one side;:as illustrated, is mounted on the columnAl preferably in an inclinedposition so that whenreceived in the cradle, the bailer, generally indicated at I 5 about the angular position illustrated. The eradlegcontains a pair. of-spaced oppositely positioned lugslfi, see Fig 3, presenting upwardly facing shoulders I! upon which the bailer body is rested as will now be described.

The bailer I5 may be of any suitable type and construction comprising a pair of relatively rotatable sections, one of which is receivable between and held against rotation by the lugs I6, while the second section is rotatable to dump the fluid charge. Typically, the bailer is shown to comprise a pair of tubular sections is and IS, the former of which comprises a pipe section 20 forming the charge-receiving chamber, and a sub 2| having 2. depending tubular extension 22 containing a dump opening 23. A frangible disc 24, received within extension 22, is seated upwardly against the sub-contained shoulder 25.

The outer bailer body section I 9 comprises a tube 2 6 threaded at 21 on the sub so as to be relatively rotatable, and containing an opening 28 into registration with which opening 23 is brought by relative rotation of the described inner body section 18, as by turning tool inserted within the recess 29. Opposite side surfaces of the lower portion of tube 26 are flattened at 30 for reception between the cradle lugs l6 and to form downwardly facing shoulders 3| which, as illustrated in Fig. 2, rest upon the cradle lug shoulder ll 1.

The bailer contains a tubular mandrel 32 carrying a combination dis-c breaker and ball check cage 33 containing the valve 34. The bottom tubular portion 35 of the mandrel may carry the usual ring, not shown, or have other details of construction immaterial to the present invention.

The bailer is operated in the usual manner by lowering it in the well until the lower portion 35 of the mandrel bottoms in the hole and continued downward movement, of the bailer body (with its sections 18 and I9 positioned as in Fig. 2) impacts and breaks the disc 26 against the mandrel head 33. The well fluid and said charge then is taken up through the mandrel in Fig. 2, eposes at past the valve 34 into chamber 36, the valve thereafter seating to retain the charge. The bailer then is removed from the well and placed in the cradle I4 as shown in Fig. 2, with the opening 28 at the open side of the cradle. It will be understood that the mandrel 32 may be dropped within the body to any location below its disc breaking position to permit access of the fluid in chamber 36 to the inner opening 23. By then rotating the inner body section 18, the outer section 19 being held against rotation between the cradle (lugs I6, opening 23 is brought into registnation with opening 29 to permit complete out flow of the charge from chamber 36. During the described fluid dumping operation, the bailer may be held against displacement out of the cradle by a pin 38 carried on chain 39 and inserted through opening 40 in the sides of the cradle.

I claim:

1. Apparatus for use in dumping a fluid charge from a well bailer having parts relatively rotatable to dump the charge, a floor-supported standard, a vertically inclined continuously open side [cradle carried by said standard and adapted to receive and support the bailer in inclined position, and means forming within the cradle an open end recess adapted to receive and hold one of said bailer parts against movement relative to the other part, said means also presenting upwardly facing shoulders upon which the bailer is rested.

2. Apparatus for use in dumping a fluid charge from :a well bailer having parts relatively rotatable to dump the charge, comprising a continution, means forming within the cradle an open end recess adapted to receive and hold one of said bailer parts against movement relative to the other part, said means also presenting upvwardly facing shoulders upon which the bailer is rested, and a bailer retaining pin insertible across the cradle through the sides thereof.
