WE'LL-BUCKET.

SPECIFICATION forming part of Letters Patent No. 618,948, dated February 7, 1899.

Application filed June 24, 1897. Serial No. 642,201. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY NOIgSEY, a citizen of the United States, residing at Memphis,

1 known as cone-top buckets,which are used in connection with driven or pipe wells.

It has for its object to improve the structure of the body of the bucket, so that the same may be formed of a single piece of metal by corrugating the upper cone portion of the bucket. Heretofore buckets of this character have been formed by constructing the cone portion of a separate piece of metal and soldering or attaching the same to the cylindrical body of the bucket, in which construction the cost of manufacture was materially increased and the strength of the bucket at its upper end diminished.

In the accompanying drawings, Figure 1 shows a perspective of the well-bucket. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1, and Fig. 3 is a detail vertical section.

Like letters of reference indicate like parts throughout the several figures of the drawings.

The letter A designates the cylindrical body I of the bucket, which is formed of any suitable metal, preferably treated or coated, so as to be non-corrodible, and which at its upper portion is formed cone-shaped, as at A. Extending upwardly from the cone portion A is a bail A riveted or otherwise secured to the cone, to which bail will be attached the means for moving the bucket in the well. The cylindrical body portion A and the cone portion A are formed of a single piece of metal, the upper portion of which is corrugated, as shown at a in Fig. 1, so that when the sheet of metal is curved into a cylindrical form the upperportion thereof forms the coned top of the bucket. These corrugations a may be formed of equal depth throughout their length; but it is preferable to form the same of gradually-increasing depth toward the upper end of the bucket, so that the body of metal will be taken up and the diameter of the cone gradually decreased from its base to its apex. At the base of the cone there is a slight bead a, from which the corrugations extend upwardly. At opposite sides at the top of the cone a seat a is provided for the ends of the bail A in which seat the bail is secured. It will be seen that by using the corrugations of gradually-increasing depth the bucket may be formed of a blank of equal width at each end, as the corrugations will take up sufficient metal at the upper end of the blank to diminish its diameter when it is assembled cylindrically to form the bucket.

As is well-known, buckets of this character are formed of substantially the same diam eter as the well or pipe in which they move, and the coning at the top of the bucket is for preventing the buckets touching the joints in the piping or projections in the well and for diminishing the resistance of the water against the bucket when the same is raised through the body of the water. By forming the bucket and cone of a single piece of metal corrugated at its upper portion all danger of the cone becoming detached from the bucket is avoided, which difficulty has been found when the cone is formed of a separate piece of metal soldered or otherwise secured to the body of the bucket. The corrugation of the metal at the cone portion forms a series of Vertical ribs, which materially strengthen the upper portion of the bucket, so that the same will not be dented or forced inwardly by striking a joint or projection in the well, and also prevents collapsing of the cone portion by reason of the pressure, either longitudinally or laterally, of the corrugations in theuse of the bucket. The lifting strain upon the bucket is exerted entirely upon the strengthened cone portion, and thus the durability of the bucket is materially increased by reason of the corrugated integral cone portion, the cost of manufacture materially decreased, and the efliciencyof the bucket greatly improved.

Having described my invention and set forth its merits, what I claim as novel, and desire to secure by Letters Patent, is-

1. As a new article of manufacture, a wellbucket composed of a singleblank of metal corrugated at its upper portion to form a con-' site sides flattened surfaces, and a bail atical top to the bucket and provided with a tached at the flattened surfaces and embail rigidly attached to said corrugated porbraced upon three sides thereby at said upper tion and arranged within the corrugations portion.
