Application October 2,

3 Claims.

This invention relates to novel assembling and anchoring or retaining means for adequately and effectively joining the base portion of a conventional pump stand to a well casing.

There has been a long felt need for the provision of practicable sanitary and, fluid-tight means to permit the flared bell-end of a pump stand to be fitted telescopically down over the upper protruding end of a well casing and to accomplish this result without the use of threads, while at the same time providing the requisite retaining connection. After due deliberation on the State regulations and requirements, I have perfected an assemblage of features, which, I believe, accomplish the desired results in an aptly fitted and reliable manner. I 1

In reducing the principles of the present inventive conception to actual practice, I have found it expedient and practicable to utilize a simple and inexpensive flanged collar and associated details, wherein the collar is secured by set screws to the upper end of the well casing and bolted to the flange of the stand and so designed as to provide a channel or receptacle for an asphaltum filler.

Other features and advantages will become more readily apparent from the following description and drawings.

In the accompanying drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure 1 is an elevational view showing a fragment of the upper end portion of the well casing, illustrating the lower portion'of the stand, and special assembling and joining means between these parts constituting the novelty of the present invention.

Figure 2 is an enlarged central vertical sectional view detailing the selection and coordination of features more satisfactorily.

Figure 3 is a top plan view of the flanged attaching or jointing collar constituting the essential features of the invention.

Figures 4, 5, 6, and '7 are detail elevational views of an eccentrically apertured adapter washer to facilitate bolting the flanged collar to the flanged stand base.

Figure 8 is a fragmentary view screw arrangement.

Reference is conveniently had first to Figures 1 and 2. Here the well casing, which is conventional, is denoted by the numeral I0, and in pracshowing the set tice theupper end thereof is preferably beveled.

to permit it to fit telescopically into the flared or bell-shaped base portion ll of the conventional pump stand l2. The bell-end is provided with an 1936, Serial N01 103,793

(Cl. 285 -l34) outstanding annular flange l3 having existing bolt holes therein such as are ordinarily employed in fastening the stand on a platform, (not shown) In accordance with the present invention, the standsimply rests firmly down on the beveled upper end of the well casing, as illustrated to. advantagein Figure 2. The connection is made through the instrumentality of the improved coupling and retaining means.

The latter means comprises an annular collar [4 having a thickened annular portion IE to accommodate-the radial set screws 16 (see Figure 8) which bear against the adjacent end portion of the well casing. At the lower end of the collar is an inturned relatively short flange H which is in effect a ledge. In fact, this flange I1 cooperates with the inner periphery of the collar in spacing said portion of. the collar from the well casingto provide a substantially V-shaped pocket to accom modate the filler, that is, the plastic filler I 8. The

feature I8 provides the desired expansion joint. At the upper end the collar is provided with a relatively wide outstanding circular flange l9. This is provided with relatively large openings or holes to accommodate the fastening bolts 20. It will be noted that the holes are tapered and are adapted to accommodate composition adapter plugs 2|. The plugs maybe of rubber, lead, or othersuitable material. A simple type is shown in Figures 4 and 5, and this is provided with an eccentric bolt hole 22 which can be turned around in an orbital path so as to accommodate the stem of the clamping bolt 20. In practice the bolt holes existing in the flange l3 vary, and for this reason it is generally necessary to have these adjustable eccentrically apertured plugs 2| to permit the bolt hole to be placed properly to insure the desired clamping action. In addition to using the plugs and bolts, I find it expedient and practical to also use metal binding or clamping-washer 23 of a diameter greater-than the plug accommodation holes. This is-advantageous in forming a fluid: tight: joint. The fluid-tight joint is, however, completed by the disposition between the flange 13 and flange [9 of a gasket 24. I J r In Figures 6 and 7, different type adapter plugs are illustrated. For example, the tapered plug 25 in Figure 6 is formed with an eccentric bolt hole 26 and provided with an integral abutment flange 21 which takes the place of the separate washer 23 shown in the assembly in Figure 2. 1 In Figure 8 the plug .28 is providedwith a washer-forming flange 29 and an eccentric screwthreaded stud 30 such as may project up through the bolt hole in the flange I3 to accommodate a on the well casing.

This pump stand is constructed to meet the requirements of the Wisconsin Well Drillers Sanitary Code. When connected'in full accordance with the instructions given herein, it will make a water-tight joint between the well casing and." hand pump without the use of a thread on the well casing or pipe.

The drawings clearly show how the connection is made. The well casing must extend at least .6 inches above the platform (not shown) to allow it to go up into the pump base so that the pump will sit directly upon the casing. Thestand requires 2% inches and at least 1 or 2 inches should be allowed between the bottom of the stand and platform. This is to prevent frost heaving of the platform interfering with the pump stand. In pouring concrete-for a pump platform, it is very important to allow a space of about 1- inches or 2 inches between the well casing and the concrete. This space is to be filled with mulsi fied asphaltum or roofing cement; this material is pliable and will give when the frost heaves the platform in winter, thus preventing any pull on the well casing. Much damage has been done to drilled wells by surface water seeping into the well because the mistake has been made of cementing up tight against the casing. Or worse still, when the cement has been poured flush with the pump stand much damage may result. In the spring, when the frost leaves the ground, you may find a pulled well casing, with the platform being held off the ground; a broken joint in the well casing, or the pump stand stripped from the casing leaving a funnel in the concrete the shape of the stand to allow water to gather and drain into the well.

Instructions for installing: Y

1. Be sure that the stand goes over the well casing, as the diameter may vary a little and may not be perfectly round;

2. Place gasket on top of stand. a

3. Set pump on top of casing in the exact desired position.

4. Bring up stand against the pump, put in bolts and draw up so that the two parts'come up close together with gasket'between them (donot draw too tight).

5. Plumb'the position of the pump, and hold in position by securely tightening the four inch set screws in the stand.

6. Remove the pump and gasket from the stand, and caulk the space as shown 'in the drawings with the materials mentioned. If roofing cement is used, a thin coating should be applied to the top of the stand before the gasket is laid.

7. Lower the drop-pipe and connect the pump to it. Apply a thin coating of roofing cement to the top side of the gasket inside of the pumpbase circle as pump bases are not always true. Then connect the pump to the stand with the four bolts, being sure to draw up tightly all bolts and set screws. This will'make a water-tight and vermin-proof joint.

It is thought that the I description taken in connection with the drawings will enable a clear understanding of the invention to be had. Therefore, a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown and described, it is to be understood that minor changes coming within the field of invention claimed may be resorted to if desired.
