Sol-Mn, Long Application April 5, 1939, Serial No.' 266,108 6 Claims. (01. lac-la) 19 for the purpose of releasing the load of cement,
or the like, within the bailer.
Another object of my invention is to provide a novel bottom valve dump bailer, in which the releasing valve or gate is actuated by a longi-. tudinal movement of the bailer within the well.
Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description, and the appended claims. 1
80 In the drawing- Figure 1 is a longitudinal, sectional view of my bailer in closed position.
Figure 2 is a fragmentary, longitudinal-sectional view oi; my bailer in open position.
8 Figure 3 is a sectional view taken on line 3-3 oi Figure 2,
Figure 4 is a plan view of the bottom valve or gate.
Referring more particularly to" the drawing.
the bailer I is mounted on the lowerend of pipe or'tubing 2. The bailer I consists of a tubular housing 8 of considerable length, and is adapted to retain a quantity of material, such as cement.
The bottom of the housing is closed by a valve or a gate 4, which is hingedly mounted on one side, as
shown at 5. by a spring finger 6, which is fixedly attached to the outside of the housing 3, and is preferably counter-sunk into the housing so that the outer surface of the spring finger is flush with the outside of the housing. A lug I on the lower I2 is fixedly attached to. the lower collar I0 but the upper end of this spring is free to move inwardly and outwardly as tension is applied to the springs. A spring catch I3 is fixedly atis tached at its lower end to the outside of the The valve is held in closed position housing 3, the upper end 01 this spring catch normally flexing outwardly to enter a slot II in the collar 9, and thus hold the collars and the springs against downward movement. When the bailer reaches the-lower casing For bore of the well I5, the spring fingers II,- I2 will be compressed, since the lower part of an oil well is always or lesser diameter than the upper part of the well. a While running into the bored hole or casing, 10 the upper collar 9 engages the coupling I6, thus limiting the upward movement of the collar and spring finger assembly. When the smaller diameter in the well is reached, the spring I2, and particularly the upper portion thereof, will be pressed inwardly and will enter the slot I4. The operator now pulls the pipe and thelbailer upwardly, and due to the frictional resistance of the springs I I, I2, the collars 9, ID will remain stationary, and the housing a will be pulled upwardly through these collars. The upper end of the spring II willpress-the upper end of the spring catch it inwardly, thus permitting the collar 9 to pass the spring I3 and continue to move downwardly. Further upward movement 95 of the housing I will cause the collar Ill to'engage the spring finger I, as shown in Figure 2, thereby disengaging the spring finger from the eye 0 and permitting the valve or gate 4 to swing downwardly, thereby releasing the- .load or 80 cement, or the-like, in the bailer. The bailer. is now returned to the surface, is again loaded, and the operation is repeated, if necessary.
Having described my invention, 1 claim:
1. Abottom dumping bailer comprising a tubular housing, a ate pivotally mounted on the lower and oi the housing and adapted to close the same, a spring finger engageable with the gate to hold the same in closed position, a pair of spaced collars slidably mounted on the housing, a plu- 40 rality oi spring arms attached .to and connecting the collars, the lowermost collar being adapted and arranged to engage the spring finger and release said finger item the gate, whereby said gate is released.
2. A bottom dumping bailer comprising a tubular housing, a gate pivotally mounted on the lower end of the housing and adapted to close the same, a spring finger enga eable with the gate to hold the same in closed position, a pair oi Iiiv spaced collars slidably mounted on the housing,
a plurality oi spring arms attached to and connecting the collars, the lowermost collar being adapted and arranged to engage the spring finger and release said finger i'rom the gate, wherell by said gate is released, a spring catch mounted on the housing and adapted to engage one 01 said collars, one end of one of said spring arms being free and adapted to engage and release said spring catch when said spring arms are compressed.
spring fingers being free at the upper end and engageable with the spring catch to release the same when the spring arms are compressed, the lowermost collar engaging the spring finger to release the same on relative longitudinal movemerit of the collar and housing.
4. A bottom dumping bailer comprising a tubular housing, a gate pivotally mounted on the bottom end of the housingand adapted to close the same, a spring finger fixedly attached at one end to the housing, the free end of said spring finger engaging the gate to hold the same in closed position, a pair of spaced collars slidably mounted on the housing, a plurality of spring arms attached to and connecting the collars, the lowermost collar being adapted and arranged to engage the spring finger and release said finger from the gate, whereby said gate is released to swing into open position.
5. A bottom dumping bailer comprising a tubular housing, a gate pivotally mounted on the bottom end of the housing and adapted to close the same, a spring finger fixedly attached at one end to the housing, the free end of said spring finger engaging the gate to hold the same in closed position, a pair of spaced collars slidably mounted on the housing, a plurality of spring arms attached toan'd connecting the collars, the lowermost collar being adapted .and arranged to engage the spring finger and release said finger from the gate, whereby said gate is released to swing into open position, a spring catch engageable with one of said collars, one end of one of said spring arms being free and adapted to engage and release said spring catch when said spring arms are compressed.
-6. A bottom dumping bailer comprising a housing, a pair of spaced collars slidably mounted on the housing, springs connecting the collars, said springs being adapted and arranged to bear against the bore or casing of a well, a gate pivotally mounted on the lower end of the housing, latch means engaging the gate, a spring catch engaging one of said collars, one end of one of said springs being free and adapted to engage and release said spring catch when the springs are compressed, one of said collars engaging said latch means on relative longitudinal movement of the collar and housing to disengage the latch means and release the gate.
