ALEXANDER BOYNTON, OF SAN ANTONIO, TEXAS.'

BAILER.

Application `:filed May 8, 1922. Serial No. 559,361.

To all whom t may concern:

Be it known that l, ALEXANDER BorN'roN, a citizen of the United States, and resident of San Antonio, in the county of Bexar and State of Texas,` have invented certain new and useful improvements in Bailers, of which the following, is a speciiication.

This invention relates to bailers especially adapted for removing such material as mud, slush and muddy water from oil and water wells.

Briefly stated, an important object of this invention is to provide a well bailer havingD a plurality of material discharge openings in the sides thereof with greater area than the cross sectional area of the bailer so that the material may be readily and conveniently discharged.

Further the invention aims to provide a bailer having simple meansy whereby the openings in the inner andouter sleeves mayr be aligned for the purpose of discharging the contents.

Also the invention forming the subject matter of this application is provided with oppositely arranged longitudinally extending openings, one of which may be employed as an inlet means for a stream of Asteam or water and the other openingl employed as an outlet for the melted mud, hot water and steam., thereby preventing the hot water and. steam from returning onto the hands of the operator., as is the case with the bailers now in general use,

A further object is to provide ya bailer having simple means whereby heavy and stiff mud may be thrust out through one side of the bailer by means of a suitable tool,`in serted from opposite side so that the mud above may drop into position between the openings and be subsequently thrust out in same manner.

The invention forming the subject matter of this application also aims to provide a bailer having means whereby the downward thrust of the same may be employed as a means for forcing the mud or other material into the bailer.

A further object is to provide a bailer in which the partscannot be accidentally disconnected when lowered in a well and which is extremelysimple and reliable in use.

Other objects and advantages of the invention will be apparent during the course of the followingf description.

ln the accompanying drawing, forming;

a part of this application and in which like numerals are employed to designate like parts throughout the same,

Figure l is a perspective of the bailer and a discharge member.

Figure 2 is a vertical section through the same.

Figure 3 is side elevation of the bailer.

F igure l is a section talren on line 4-*4 of Figure 2.

ln the drawing` wherein for the purpose of illustration is shown a preferred embodiment of the invention the numeral designates an outer sleeve having its forward portion interiorly screw threaded as indicated at 91 for engagement with the rear portion of bailer bottom 92. This bottom is, as illustrated in Figure 2 formed with an internal annular shoulder 93 upon which an annular valve seat 91lis mounted. las further illustrated in Figure 2, a flap valve 95 is pivoted as indicated at 96 to the top of the valve sea-t and when mud is introduced into the bailer the valve is elevated. However. the flap valve 95 serves as a positive and reliable means for preventing; the escape of mud through the lower end of the bailer. Yt will be observed that the valve seat and the valve do not substantially decrease the cross sectional area of the inlet portion of the bailer and consequently little resistance is offered to the admission of mud inte the bailer. Further, the forward portion of the bailer'bot tom. is formed with lil-shaped recesses 9i which provide a large inlet means at the lower end of the bailer and churn and mii; the mud.

ln carrying' out the invention an inner sleeve 98 is arranged within the outer sleeve and is limited in its rotation with relation to the outer sleeve by means of a pin or set screw 99 which operates in an arcuate transversely extending slot 100 in the outer sleeve.

In practical operation outer sleeve 90 will rotate upon inner sleeve 98 by turning` upon threads 91.

yThe `slight longitudinal movement of the sleeve 98 when one sleeve is rotated on the other is permitted bythe fact that the set screw 99 is freely received in the slot 100.'

The pin 99 not only serves as a means for limiting' the rotation of one sleeve with relation to the other but also serves as a means for preventing longitudinal movement of one sleeve with relation to 'the other. in carrying out .invention the lower portion of the inner sleeve v96 is exteriorly screwthreaded for engagement with the intermediate portion of the bailer bottom which as illustrated in Figure 2 is formed with screw threads 102; The bailer bottom 92 cannot become accidentally disconnected from the outer sleeve as there are approXimately 16 threadsl to the inch at the connection 91 while there are 8 threads to the inch at the connection 102. This would cause a binding between the parts as the result of any independent rotation ot the bailer bottom, which binding would prevent the loss or disconnection of the bailer bottom 92. It inner sleeve should become broken from bottom at threads 91 the bottom would not be lost but would be lifted out of well by pin 99, which thus becomes a fishing tool' in case oi a disconnected bottom.

In summarizing the connecting means of the various parts oi the bailer, it will be seen that the bailer vbottom 92 has threaded connection with the inner and outer sleeves which prevent the bailer bottom 92 from being accidentally lost when in the well. The connection between the inner and outer sleeves and the bailer bottom co-operates with the pin 99 to absolutely prevent the loss of the outer section or the bailer bottom. Should the connection 102 be broken warning of the fact will be given by the hanging ofthe outer section 102 on the pin 99 whereupon the broken connection may be quickly remedied by merely cuttingA new threads on bottom of inner sleeve 98.

The inner and

outer sleeves

90 and 96 re` spectively are formed with elongated slots 105 and 106 respectively through which mud or other material may be quickly discharged. There are two of the openings 105 and two ot the openings 106 and these openings have a combined area greater than the cross sectional area ot the bailer so that when the openings are in registration the contents ot bailer may be quickly discharged. lf the mud is thick and will not l'low readily a steam pipe or hose may be introduced into one of the openings 'formed by the slots 105 and 106 for the purpose of melting the mud. In this case the steam hose is introduced through one of the openings and the mud tlows out through the other openings. 1t is thus seen that the steam will not return through the opening by which it enters. lll/'hen it is desired to bring the openings 105 and 106 into registration the lrnurled portions 108 may be manually gripped and the outer sleeve rotated whereupon the inner and outer openings will be brought into registration for allowing discharge of the mud.

The upper end of the outer sleeve 90 is formed with notches 161 which are engaged by a tool employed for rotating the sleeves.

It however, it is not desired to manually rotate the outer section, the bailer may be.

introduced into a cylindrical discharge member 110 having its upper end flared as indicated at 111 so that the bailer will be self guided into the cylinder.

The cylindrical discharge member 110 is provided with longitudinally extending` slots 114 adapted for registration with the slots 105 and 106. The bailer bottom 92 and the outer sleeve 90 are formed with aligned grooves 116 for the purpose of receiving a guide pin 117 carried by the cylindrical discharge member. Figure 3 illustrates that the groove 116 begins at the apex oit' one ot the V-shaped recesses 97 which incidentally serves as a means for guiding the pin 117 into the groove.

Figure 3 also illustrates that the outer sleeve 90 is provided with a spiral or curved groove 120 which communicates at its forward end with the rear end oit the groove 116 and said spiral groove 120 is adapted to slidably receive a second guide pin 122. Then the pin 122 is received within the spiral groove the outer sleeve is slightly rotated so that the foremost longitudinally extending groove 116 will be in a position to receive the pin 117.

In operation when the bailer is introduced into the cylindrical discharge member 110 the longitudinal groove 116 lirst receives the guide pin 122 and then the spiral groove 120 receives the guide pin 122 and` simultaneously with the entrance ofthe guide pin 122 into the spiral groove 120 the foremost pin 117 is received in the longitudinally extending grooves 116 whereby the parts are rotated so as to bring the slots 105 and 106 into registration.

In operation no time is lost in dumping as when the device is introduced into the cylindrical container 110 the openings in the inner and outer sleeves are automatically brought into registration whereupon the contents of bailer may be readily discharged. llVhen the apparatus is introduced into the well the thrust of the same is utilized as a means for forcing the mud or other material into the inlet end of the bottom 92 and consequently the bailer is rapidly filled.

In churning the bailer bottom 92 may be bumped against the bumper 125 carried by the lower portion of the cylindrical discharge member 110, the babbitt bumper 125 is mounted upon a bottom plate 126 torniL ing a part of the cylindrical discharge member.

In summarizing. it will be seen that the mud is introduced into the bailer at the lower end of the same and that it is discharged laterally of the bailer so that the discharge opening is not in any. way restricted when churning the bailer whereby the maximum area for the discharge of the material is provided for. i

It is to be understood that :teem elf the invention herewith shown and described is to be taken as a preferred example of the same and that such minor changes in arrangement and construction of parts may be made as Will remain Within the spirit of the invention and the scope of what is claimed.
