WELL-BUCKET. 7

Specification of Letters Patent. Patented July 11, 1911',

Application filed October 17, 1910. Serial No. 587,577.

To all whom it may concern:

Be it known that I, PERRY THOMAS, a citizen of the United States, residing at Silverton, in the county of Briscoe and State of Texas, have invented certain new and useful Improvements in Well-Buckets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in buckets, and more particularly to that class most commonly known as well buckets.

An object of this invention is to provide a device of this class provided with a valve of such construction that when the same is lowered into the well fluid will be admitted therein, and when the same is withdrawn the said fluid will be retained against spilling.

Another object of this invention is the provision of a bucket comprising a cylindrical shaped casing, provided with oppositely tapered ends, one of which is provided with a valve, the same, when the bucket is lowered into the well, adapted to contact with the bottom thereof and admit fluid into the bucket, the said valve closing as the bucket is removed from the well by the pressure of the fluid thereon and retaining the same against removal from the said bucket.

A further object of this invention is to improve and simplify devices of this character, rendering them simple in construction, comparatively cheap to manufacture, reliable and eflicient in use and readily operated.

IVith the above and other objects in view this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more particularly described, claimed and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved bucket, and Fig. 2 is a vertical sectional view therethrough, taken on the line a-a of Fig. 1.

Referring to the drawings by characters of reference, the numeral 1 designates generally my improved bucket, comprising a substantially cylindrical member 2, provided at its ends with oppositely tapered extensions 3 and 4:, the upper end of which carries a ring 5, to which any suitable suspending means may be attached. The opposite tapered end of the bucket has secured thereto a cylindrical sleeve 6, provided at its upper end with a horizontal flange 7 adapted to contact with the inner face of the tapered end 4 and serve to reinforce the same. An apertured plate 8 is riveted, or otherwise secured, to this flange 7, together with a valve seat of any desired flexible material for the reception of a valve 9, reinforced, as at 10. by a suitable metal plate, and provided upon its lower face with a valve stem 11, comprising a substantially inverted U-shaped 'member 12, the opposite sides of which areconnected by a suitable brace 13. In order to prevent the total displacement of the valve from the valve seat, a pin 14: connects the opposite sides of the cylindrical sleeve 6 and passes through the opposite legs of the U-shaped valve stem.

From the foregoing disclosure it will be manifest that as the bucket is lowered into the well, the valve stem, which extends below the lowest extremity of the bucket, will obviously contact with the bottom ofthe well, raising the same and permitting the fluid to enter the receptacle, and as the receptacle is withdrawn from the well the pressure of the fluid contained within the said bucket will force the valve against the seat and retain the fluid therein.

Having thus fully described this invention, what I claim as new and desire to secure by Letters Patent is:

1. A well bucket such as described comprising a tubular member having oppositely tapered ends, suspending means secured to one end thereof, a sleeve located in the opposite end of the said bucket, a flange upon the said sleeve engaging the end of the bucket, a reinforced valve seat secured to the flange, a

valve engaging the said seat, and means for operating the valve and retaining the same against total displacement from the bucket.

2. In a well bucket such as described the combination with a tubular member having oppositely tapered ends, supporting means secured to one end thereof, a sleeve located in the opposite end of the said bucket, a flange upon the said sleeve engaging the end of the bucket, a valve seat supported by the flange, a valve engaging the said seat,

provided With a substantially U-shapecl stem In testimony whereof I affix my signature adapted to operate vertically Within the in presence of tWo Witnesses.

sleeve and unseat the valve by its contact 7 with the bottom of a Well, or the like, and PERRR THOMAS means for limiting the movement of the valve, substantially as and for the purpose set forth.

Witnesses:
