BAILER.

SPEGFICA-TION forming part of Letters Patent N o. 680,163, dated August 6, 1901.

I Application filed April 25, 1901. Seria-l No. 57,456. (No model.)

To @ZZ whom, it may concern:

Be it known that I, KENNETH MooRING, a citizen of the United States, residing at Rockland, in the county of Washington and State of Ohio, have invented new and useful Improvements in Bailers, of which thefollowing is a specification.

This invention relates to certain new and useful improvements in bailers for removing fluid, mud, or debris from wells, and is particularly adapted for use in connection with the drilling of oilwells.

The invention aims to construct a bailer not only adapted for removing water or other matters from a well, but also is particularly adapted for supplying water to the bottom of the well, which is very essential when the rock caves or falls in.

The inventionfurther aims to provide new v and novel means for keeping the valves unseated when it is desired to discharge the water from the bailerwhen the latter is at the bottom of the well and when elevating the bailer after the discharge of the water.

The invention further aims to construct a` bai-ler'so that it is not necessary to invert the same to discharge the contents therefrom which have been bailed from'the well.

The invention further aims to construct a bailer which shall be extremely simple in construction, strong, durable, ei'cientinits operation, and comparatively inexpensive' to manufacture; and to this end it consists of the novel'combination and arrangement of parts hereinafter morespecifically described, illustrated in the accompanying drawings,

and particularlyw pointed out'in the claims lthe clutching mechanism retaining the'valves in an openposition.l

Referring to the drawings by reference-numerals, the cylinder of the bailer is formed of an upper and lower section l 2, respectively, ot' any preferred length. The sections abut against one another and are connected together by means of the cylindricalband 3, engaging the inner face of the sections and secured thereto by means of the rivets or other fastening means 4. The band 3 not only connects the sections of the bailer-cylinder together, but also forms a stop forlimiting the upward movement of the sliding valve, to be hereinafter described. The lower end of the section 2 of the bailer has secured therein the shouldered collar `5. The latter is cut away on its outer face to form the shoulder or ridge 6, upon which is seated thelower end of the section 2, the latter being secured by means of the rivets 6 to the upper portion of the collar 5, which projects into the section 2. This upwardly-projecting portion of the collar 5 forms a stop for limiting the downward movement of the slide-valve 7.

The slide-valve 7 is arranged within the lower section of the bailer between the band 3' and collar 4 and is adapted to close the openings 8, formed in the lower section 2. The slide-valve 7 consists vof a hollow cylin-Y drical collar, with its outer diameter substantially the same as the inner diameter of the lower section 2. At the lower end of the inner face of the valve 7 an inwardly-projecting annular iiange 8 is formed integral therewith. The lower face of the flange 8' forms a lvalve-seat for'the lower choke-valve 9 and its upper face a seat for the upper choke-valve 10.

The reference-numeral 1l denotes an elongated valve-stem having the lower portion thereof screw-threaded to receive the chokevalves 9 l0, the-former adapted to close the opening through the flange of the slide-valve for forming a closure for the bottom of the cylinder., The choke-valve 9 is retained in position by means of the jam-nut 12, mounted Aon the'lower end of the valve-stem 1l and engaging the valve 9. and l0 are arranged upon the stem 11 sothat the flange S will be interposed between them. By this arrangement the choke-valve lO will carry the slide-valve downwardly and the choke-valve 9 will elevate the slide-valve 7 The choke-valves 9 l IOO when the valve-stem 1l is raised or lowered mwhen the bailer is lowered or elevated with in the well.

The reference-numeral 12 denotes a bail secured to the upper section l and through which extends the valve-stem ll. The latter is provided with a stop-nut 13, adapted to engage the bail 12', and further provided at its upper end with a link 14, to which is connected the sand-line for raising and elevating the bailer. The link 14 is swivelly secured to the stem l1.

Connected to the upper end of the stem 11 between the nut 13 and link 14 is a clutch mechanism for retaining the slide-valve 7 and choke valve 9 in an open position. The clutch mechanism consists of a casing 15, having each of its sides slitted. The portions between the slits in the sides are bent to form the ears 16 17, through which extends the fastening-bolt 18. The ears 16 17 are bent in such a manner that they are adapted to project over the stem l1 and are adjustably secured to the latter by means of the bolt 18,

The referencenun1erall9 denotes a springpressed clutching-arm, which is pivotally connected at one end to the casing 15 by means of the pin 20, and the upper end of said arm engages the coiled tension-spring 21, arranged in the upper end of the casing 15. The lower end of the said arm is formed into a beak or hook 22, which is adapted to engage the bail 12 and prevent the elevation of the valve-stem l1, thereby retaining the slide-valve 7 and choke-valve 9 opened when desired. The clutching mechanism is adjustably secured to the stem ll, so that the same can be elevated when desired, so that the beak or hook 22 will not engage the bail 11 and prevent the closing of the valves 7 and 9.

The operation of the device is as follows: Assuming that the same is to be used as a bailer and the clutching mechanism is adjusted so that the same will not engage the bail on the upper section, the bailer is loW- ered within the well,the cylinder sliding downwardly`on the valve-stem, thereby closing` the opening in the lower section of the cylinder, owing to the slide-valve engaging the band or stop 3. At the same time the chokevalve 9 will close the opening through the flange 8. When the bailer reaches the bottom of the well, the valve-stem will be lowered, lowering the slide-valve 7 and choke-` valve 9, permitting the water or other sediment to enter through the opening 8 and the opening through the flange. When the bailer is raised from the well, the stem 1l will be elevated, first closing the opening 8 by means of the slide-valve 7 and the opening through the flange 8 by means of the choke-valve 9. When the bailer is at the top of the well and it is desired to remove the contents thereof,

the bailer is set upon the ground or other desix-able place. The stem l1 will fall by gravity, lowering the slide and choke valves, and permit the contents to be discharged. When it is desired to lower water into the well by means of the bailer, the clutching device is arrangedupon the valve-stem so that the beak or hook will be above the bail; but when the stem is lowered the beak or hook will ride over the bail andengage the lower face thereof, such action being caused by the spring 21, the clutching-arm, with its beak or hook, being operated in the manner above when the bailer is at the bottom of the Well. When the bailer with the water is lowered in the well, owing to the fall of the cylinder or the elevation of the valve-stem, the opening 8 and opening through the ange 8 will be closed by the slide and choke'valves 7 9, re-

s pectivel y. When the bailer has reached the bottom of the well, the beak or hook of the clutching-arm, owing to the lowering of the stem 11, will ride over the bail and engage the same, preventing the closing of the openings by the slide and choke valves 7 9. This prevents the hailing out of the water supplied or other sediment when the bailer is elevated.

It is thought the many advantages of my improved bailer can be readily understood from 4the foregoing description, taken in connection with the accompanying drawings, and it will be noted that minor changes may be made in the details of construction without departing from 4the general spirit oi' my invention.

Having lthus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
