2 Claims. (Cl. 166-19) This invention relates to a sand bailing device sanded or mudded up, the bailer isconnected to and is particularly, though not exclusively, the sand line and lowered into the well, the bailer adapted for cleaning the sand and mud from the being empty as in Figure l with piston l8 at the bottom of oil and water wells. bottom of bailer body 6, valve 9 closed against Another important object of the invention is valve seat Hand with packing rings IS on piston to provide a deep well bailer which loads autol8 and stuifing boxes l6 and H all in operative matically at the bottom of the well, and also unsealing position the bailer cylinder body 5 havloads itself when brought to the top of the well. ing been filled with air at atmospheric pressure Another object of the invention is to provide at the surface. The bailer continues downwardly 10 a simple yet effective means by Which the slush until the bottom is reached, whereupon by the 10 at the bottom of a deep well can be forced into submerging of the shoe Ill in the mud at this time a container and when brought to the top the the descent of the bailer body ceases, and the pressure which has been accumulated and locked weight of the stem 1 with the slack of the sand in the bailer while at the bottom of the well can line pushes the foot valve 9 open.

It is noted that in loading the bailer, and not the'foot. the bailer can be raised and lowered in a sloshing 25 Other objects and advantages of the invention or stirring-up motion without looking the valve will become apparent from the following dethrough the actuation of trigger l5, even though scription taken in connection with the accomeach time the bailer is raised the valve 9 contacts panying drawing in which Figure 1 is a vertical the seat H until the body container 6 is filled cross-section of the bailer when empty and ready and piston it having moved to the top of body 6 to load.

While only one form of this invention has been In operation, when the drilled well has become shown and described herein, it will be understood 55 that various modifications and changes may be resorted to without departing from the spirit of the invention or the scope of the following claims.

What is claimed is:

1. A hydrostatic pressure bailer, comprising a barrel having a closed head at one end forming a collar, a valve controlling the other end of the barrel and opening outwardly, a valve stem in said barrel and attached to said valve, -a floating means within said barrel slidably mounted upon the valve stem, said stem being connected at its lower end to said valve and extending slidably through and snugly engaging in said collar, suspending means on the upper end of said stem, the above mentioned floating means snugly engaging the inner walls of the barrel and separating the barrel into lower or intake chamber and closed upper or air chamber, said floating means being movable to vary the volumes of said chambers, caused by the necessity of equalizing the charging pressures in the said chambers when loading and unloading the bailer.

2. A pressure operated bailer having an inlet and outlet opening at its lower end with a downwardly facing valve seat in said opening, means for lowering said bailer into the well and pulling it out comprising a rod extending slidably through the bailer and attached at its lower end to a valve seating on said valve seat from below, a floating member slidably mounted on said valve rod within the bailer and closely contacting the inner wall of the same, dividing the bailer into upper air and lower charge chambers, of varying capacities, the upper end of the bailer being closed by a head member forming a collar in which said valve rod is slidably mounted, a latch mechanism on the upper surface of said collar, said latch mechanism comprising an element for engaging a shoulder on said rod when the valve is in closed position, a latch actuating mechanism
