WEIGHT FOR SINKING WELL CASINGS.

To aZZ whom t may concern.:

Be it known that I, WILLIAM H. CATER, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in l/Veights for Sink` ing Vell Casings, of which theV following is a specification.

In the sinking of well-casings and similar structures, it is desirable or necessary to weight the top, exposed end thereof to facili tate its downward travel. 1

AIn some instances, it is required that the weight shall be unevenly disposed or arranged on the casing, as for instance, when the latter exhibits a tendency to descend not exactly vertically.

Weights used for this purpose are ordinarily exposed to the weather and are not infre uently subjected to rough treatment.

y present invention aims to provide a new style and type of such weight which may be easily and quickly applied to the well-casing, whose position thereon may be varied or shifted with facility, which will not become damaged or injured in ordinary service, and which may be readily handled and brought to position for Isupport on the casing, etc.

For attainment of these and other desirable objects, I have provided the present desirable and preferred embodiment of the invention, illustrated in the accompanying drawing, forming a part of this specification, and throughout the several views of which like reference characters have been employed to designate the same parts.

Those skilled or trained in this art will have no diiiiculty in understanding the struc.- tural and functional advantages of the new weight from this illustration and from the following detailed description.

In the drawing referred to:

Figure 1 is a plan view of the top end of the well-casing or screen equipped with a plurality of the new style of weights; and

Figure 2 is a vertical section on the line 2-2 of Figure 1.

By reference t0 this drawing, it will be seen that the top or upper end section of the upright well-casing or screen being sunk or driven down into the earth is Supplied with the reference numeral 11.

casing 12, conveniently open at both ends, and partially lilled with a mixture 413 of comparatively small iron or other heavy members or particles embedded in cem-ent or concrete, whereby the loaded shell thus has substantial and adequate weight to perform its required function.

This encased, hardened mixture may conveniently or appropriately extend to the lower end of the shell as shown, but it terminates short of the upper end thereof leaving a suitable space or cavity.

In such filling, before it hardens or sets,

the headed stem or shank 14;v of an eye-bolt is embedded, the loop oreye 15`of such bolt projecting out of the iilling or charge and being located, however, within the shell in the space thereof at its upper end, all as is clearly shown, whereby the eye of the bolt is not likely to become damaged or injured.

One side-wall of the shell is internally reenforced by a plate 16 riveted thereto, the wall of the shell and such plate having registering holes or apertures `17.

These weights, which can be easily rolled around as required without injury to bring them to suitable position, because they have no projections vsubject to damage, may be lifted into place or into the correct loca-tion by any appropriate hoisting means applied to their eye-bolts.

Such weights are designed to be held or fastened around the top of the casing by hooks 18 taking or extending over the top margin of the casing and into the holes 17, as is fully presented in the drawings, the unfilled or vacant spaces in the tops of the weights receiving or accommodating the inwardly-protruding parts of these sustaining hooks.

If additional weights are required to be applied, they may be hooked on to the other weights already hung on the casing, in which case the cavities in the weights receive both ends of the fastening hooks.

In this way, any reasonable degree of downward pressure may be applied or imposed on the casing by merely attaching additional weights, all of which will be in substantially the same horizontal plane, so that they will not interfere with the descent of the easing,
