Claims. (01. ass-27 This invention relates to deep-well pumps'and' moreparticularly to an improved means .forxsupportingithe upper end ofthe. well column. It is. common practice to supportv a well columnby providing itwithan annular flange at its upper. end and by bolting such flange. to the lower side of a base plate which supports a housing enclosing' a pump-driving motor or gearing through which a pump. shaft extending. downwardly through the columncan be connectedto a source of power. It is also common practice to connect the upper 'end-of'the wellcolumnto a discharge elbow which discharges horizontally,. and. frequently the discharge elbow is madeintegral with the base" plate. In a: construction such as that last described, when it is desired-to change thedirection in which the discharge elbow discharges, it is necesary to rotate about the axis of the column both the base plate and the column itself. In some instances, such an operation is rendered impossible or impractical because of the nature of the support upon which the base plate is mounted. Greater freedom for angular adjustment of the discharge elbow about the axis of-the pump column can be provided by making the'elbow independentof the base; but in su'ch an-arrangementtwo sealed joints are required, one between the base and the top of the'column and the other between the base and the elbow. Further, in such old constructions, the entire weight of the well column and the pump at its lower end is supported through the bolts by which the column-flange is secured to the base plate. Such bolts are stressed in tension, and may tend to work loose as a result of vibration.

It is the object of my invention to provide an improved mounting or support for the upper end of a well column. Another object of my invention is to provide a column-mounting in which the column will be supported otherwise than through parts stressed in tension. A further object of my invention is to provide a column mounting which will permit ready angular adjustment of a discharge elbow without the necessity for rotation of the entire column and the base from which it is supported.

In carrying out my invention, I employ a base plate through which there extends an opening large enough to pass the well column and the pump at its lower end; and on the upper end of the well column I provide a rigid flange of larger diameter than such opening so that the flange may rest on the upper surface of the base plate with the column extending downwardly through the opening and well casing. A discharge elbow a z is secured to the upper face of the column-flange through means which permit its attachment in any of various positions angularly spaced about the column-axis.

In the accompanying drawing illustrating my invention, the single view is aside elevation, in partial section, of a pump-head and. column mounting.

The construction illustrated in the drawing comprises a base plate In through which there extends anopening H large enough to pass the well-column l2 on the lower end ofwhich a pump (not shown) is mounted; The extreme upper end of the well-column i2 is provided with an outwardly projecting flange I3 large enough in horizontal dimensions to extend outwardly beyond the sides of the opening I l in the base plate. As shown, the-flange I3 is made as a separate element and is rigidly united with the upper end of the well-column l2 by welding, as indicated at Hi. If desired, the flange 13 may be provided with a pilot portion l5 which extends into the opening I l to locate the flange l3 and the well column horizontally in definite position with respect to the base plate It. Screws 16 extending through the flange l3 and into screw-threaded holes in the base plate It! serve to secure the flange and column to the base plate.

A discharge elbow I8 is mounted on the upper face of the flange l 3 with its inlet opening aligned with the column l2. As shown, the flange I3 is counterbored and the elbow i8 is provided with a shallow boss which is concentric with the inlet opening of the elbow and which, by entering the counterbore in the flange l3, insures alignment of the discharge elbow with the column I2. For the purpose of securing the discharge elbow in place on the flange 13 it is provided with a circumferential flange 20 having an annular series of equally spaced holes 2| adapted to receive studs 22 screw-threadedly mounted in and extending upwardly from the flange l3. Nuts 23 on the upper ends of the studs 22 clamp the flange 2E! firmly against the flange l3. A gasket 24 is seated in the base of the counterbore in the flange I3 to be compressed by the co-operating bosses on the elbow l8 as the nuts 23 are tightened.

In line with the column l2, the outer wall of the discharge elbow is provided with a packing gland 26 which rotatably receives a pump shaft 2! extending downwardly through the well column l2 to drive the pump at the lower end thereof. The projecting upper end of the shaft 21 is operatively connected to a driving means, such as an electric motor 28, enclosed and supported by a housing 29 which is in turn supported from the base plate l0. Conveniently, the lower end of the housing 29 is provided with an inwardly extending annular flange 3! which receives an upwardly projecting pilot 32 provided on the base plate l0 concentric with the well column. Screws 33 extending through equally spaced openings in the flange 3| and into the base plate 10 secure the housing 29 to the base plate.

The discharge opening of the elbow I8 is presented laterally for connection to a horizontal discharge plate 35 which extends through an opening 36 in the side of the housing 29.

It is to be noted that the flange l3, which is effectively integral with the well column l2, rests on the upper surface of the base plate H], whereby the weight of the column and the pump at its lower end is transferred directly to the base and is not transmitted through the screws l6 by which the flange I3 is secured to the base. As a result, no loosening of the screws [6 will permit the well column to drop in the well. The direction in which the elbow l8 discharges and the pipe 35 extends can be varied by removing the nuts 23 and screws 33 and rotating the discharge elbow and housing 29 about the axis of the well column. In this operation, the base plate l0 remains stationary and the flange I3 and well column remain attached to the base by the screws 16, so that it is unnecessary to rotate either the base plate or the well column in changing the direction in which the elbow l8 discharges.

I claim as my invention:

1. In a well-head, a horizontal base plate hav ing an opening extending through it, a well column extending through said opening, said column being provided at its top with an integral flange projecting outwardly beyond the sides of said opening to rest on the upper surface of said base plate and thereby support the weight of the column, said flange having a downwardly projecting pilot portion located in said opening, a discharge elbow having an inlet opening aligned with the well column and a laterally presented outlet opening, and means for securing said elbow in any of a plurality of positions angularly spaced about the axis of the well column.

2. In a well-head, a horizontal base plate having an opening extending through it, a well column extending through said opening, said column being provided at its top with an integral flange projecting outwardly beyond the sides of said opening to rest on the upper surface of said base plate and thereby support the weight of the column, a discharge elbow having an inlet opening aligned with the Well column and a laterally presented outlet opening, and means for securing said elbow in any of a plurality of positions angularly spaced about the axis of the well column.

3. The invention set forth in claim 2 with the addition that said elbow is provided with an annular flange above the flange on said column, said elbow flange being provided with an annular series of equally spaced openings, said elbowsecuring means comprising screws extending through said openings and into said column flange.

4. The invention set forth in claim 2 with the addition that said column flange is counterbored, said elbow being provided with a pilot received in the counterbored portion of said flange, and a compressible gasket between said pilot and the bottom of the counterbore.

5. In a well-head, a horizontal base plate having an opening extending through it, a well column extending through said opening, said column being provided at its top with an integral flange projecting outwardly beyond the sides of said opening to rest on the upper surface of said base plate and thereby support the weight of the column, and means for securing said flange to said base plate.
