THOMAS A. BURKELLOW, OF WASHINGTON, PENNSYLVANIA.

OIL-WELL BAILER.

SPECIFICATION forming part of Letters Patent No. 400,896, dated April 9, 1889.

Application tiled July 24, 1888. Serial No. 280,904. (No model.) l

To all whom, it may concern:

Be it known that I, THOMAS A. BUEKELLow, a citizen of the United States, residing at IVashington, in the county of lVashington and State of Pennsylvania, have invented new and useful Improvements in Oil-Tell Bailers, of which the following is a specification.

My invention relates to an improvement in bailers for oil-wells; and it consists in the construction and arrangement of parts hereinafter described, and pointed outin the claim.

The object of my invention is to provide a bailer for oil-wells, or wells of small diameter, which will effectively stand the shocks and constant wear caused by its contacting with the sides of the well. I attain this object by the construction illustrated in the accompanying drawings, wherein like letters of reference indicate corresponding parts in the several views, and in which*- Figure l is a perspective view of my improved bailer, and Fig. 2 is a vertical section of the same.

In the drawings, A represents t-he sides of a cylindrical bucket or bailer, which is composed of aseries of sections of metal, B, B B2, and B3. edge braced and secured to a thick outer me tallic hoop or band, C. The lower edges of the sections B', B2, and B3 are inserted, respectively, in the upper end of the preceding section, their edges being overlapped and rigidly secured together by rivets or otherwise. The upper edge of the upper section, B2, has a brace, hoop, or band rigidly secured thereon. This hoop C is of a thickness corresponding to the thickness of the hoop O, and forms a shield or guard, as well as a brace, for the upper edge ofthe bailer.

D is the bail or handle, which is extended down on each side of the bailer and on the inside thereof, at which point it is rigidly secured, thus bringing the bail below the plane of the sides of the bailer.

To successfully brace the sidesA and couple or firmly unite the several sections, and also to guard the side and protruding edges of the sections, I place a series of vertically-extending braces or guards, E, E', and E2, on the sides of the bailer. These brace-guards are constructed of narrow strips of hard metal, of a thickness equal to that of the hoops C and C', and are riveted on said bailer. The guards E and E are placed a short distance apart,

The lower section, B, has its lower their lower ends abutting against the ring or hoop C, and their upper ends being carried up beyond the upper edge of the lower section a distance sufficient to admit of their being rigidly secured to the section B. The upper ends of guards E are carried up beyond the lower edge of the section B2, and are there riveted to said section, thus making a direct connection between the sections B, B', and B2. The brace-guards E2, which unite the sections B2 and B2, are placed so as to extend from a point 'near the bottom of the section B2 up to the bottom of the section B3, at which points they are secured. The upper edges of the guards E, E', and E2 are beveled, and also the lower end of the guard E2. This is to preventtheir direct contact with obstructions. By this arrangement it will be seen that as the bailer is lowered in the well its sides will be protected from the sharp edges of projecting rock, and also from the constant Contact of the sides of the well.

By placing a multiplicity of guards on the bottom section this portion is made more secure, and the wear coincident with this portion is in a measure entirely overcome.

It is evident that many minor changes in the construction and arrangement of my device can be made and substituted for those shown and described without in the least departing from the nature and principle of my invention.

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

The bailer herein described, consisting of the cylindrical metallic sections B, B", B2, and B2, fitting, respectively, in each other, the edges of the lower sections overlapping those of the upper sections, the thick metallic hoops C and C on the top and bottom edges of the bailer, andthe series of vertically-arranged guards E, E', and E2, of a thickness equal to the thickness of the hoops, their upper ends being beveled and projecting beyond the overlapping edges of the sections, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.
