WELL-CURB Specification of Letters Patent.

Patented March 3, 1908.

Application filed August 30. 1907. Serial No. 390.843

T all whom it may concern:

Be it known that I, JAMES F. SYZE, citizen of the United States, residing at Yorktown Heights, in the county of WVestchester and State of New York, have invented certain -new and useful Improvements in Well- Curbs, of which the following is a specification. a

1 The present invention appertains to the sinking of wells, being designed most especially to minimize the danger from caving in, and also to facilitate the work when sinking a well in soft, sandy, or loamy earth and when constructing cess-pools or like underground work requiring a wall or lining.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in. which:

Figure 1 is a perspective View of a well embodying the invention. Fig.2 is a vertical central sectional view of a well embodying the invention. Fig. 3 is a detailed per spective view of the base. Fig. 4 is a detailed perspective view of a curb section.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The invention consists of a sectional curb and a sectional base the latter being preferably constructed of metal whereas the curb sections are preferably formed of cement or like material usually employed in the formation of artificial building blocks. The curb is preferably round in horizontal section and comprises a series of courses, each course being composed of secti0ns,'and having an interlocking tongue and groove joint to prevent displacement of the courses and the sections of one" course being arranged to break joint with the sections of the adjacent course so as toform a substantial structure in which each of the sections or elements are bonded or tied.

The base is slightly larger in diameter than the diameter of the curb so as to prevent binding of the curb and admit of the same settling as the well is deepened in the sinking thereof. A rim 1. projects upward from the outer edge of the base and receives the lowermost section of the curb so as to prevent lateral displacement thereof. A rim 2 is constitutes a shoe. The outer edge of the base flares from top to bottom and forms an edge 3 which acts as a cutter to remove projecting portions after the base has been undermined sufficiently to cause the combined weight of the base and the curb resting thereon to descend. The base may consist of any number of sections 4 and the end portions of the sections are widened as indicated at 5, and apertured as at 6, to receive .bolts or like fastenings 7 for securing the sections when assembled. Clips 8 overlap the joints formed between the sections 4 and have openings in their end portions to register with the openings 6 so as to receive the bolt or fastening 7. The space between the outer edges of the clips 8 and the inner edge-of the rim 1 corresponds approximately to the thickness of the curb sections to admit of the same resting squarely upon the base. In arranging the sections the elements of the base and curb are disposed so as to break joint thereby equalizing and distributing the load and strain upon all parts.

The curb sections 9 are of like formation and are interchangeable so as to be employed in any course, the sections of a course unitedly forming a circle. A tongue 10 is provided at one edge of each section 9 and a groove 11 is formed at the opposite edge so that when the courses are formed the tongue and groove match and form an interlocking joint to retain the courses and the sections in proper position. The sections 9 may be formed of cement or other material generally employed in the manufacture of artificial building blocks, and are molded or pressed into the'required shape and when set or'thoroughly hardened are used in the manner well understood in the formation of underground structures, such as the sinking of shafts, wells, or the like. A recess 12 is formed in the inner side or wall of each sec tion and constitutes a foot rest which facilitates ingress and egress from the well or shaft.

The invention is particularly advantageous in the sinking of wells, shafts, or the like in the ground which is, soft or composed of strata of sand, gravel, loam or the like which naturally tends to cave in unless supported when excavating therein. In accordance with this invention the base is placed in position and theseveral sections connected so as to form in effect a substantial structure pendent from the outer edge of the base and 1 after which a number of sections of curb are course, and after the same has been sufficientlyundermined it will descend by its own welght and the superimposed weight of the first course. The second course is now placed upon the first course and the excavation continued until the base again descends with the two courses resting thereon. Successive courses are placed in position and successive excavations made, the base and portion of curb resting thereon lowering at each operation. After the well or shaft has been sunk to the desired depth the bolts or fastenings 7 are removed and the clips 8 and sections 4 of the base removed to be again employed in other work.

The curb may be of any diameter or outline in horizontal section and is lowered at intervals by excavating theearth beneath the base to a depth corresponding approximately to the height of a course of the curb section. The curb protects the workman from danger and supports loose earth caving in as the well or shaft deepens. The curb besides protecting the workmen forms a lining.

' for the lodgment of reptiles or other foreign matter which tend to foul water used for domestic purposes. The recesses 12 present foot holds which-enable a person to climb into or out of the well or shaft and avoid the necessity for the use of a ladder or projecting parts which would tend to catch foreign objects or form ledges for growths. The earth removed from beneath the base in the sinking of the well is adapted to be discharged through the base and curb by means of a bucket or pail as will be readily understood.

Having thus described the invention, what is claimed as new is:

1. The means for use in connection with the sinking of the well, shaft or the like comprising the combination of the curb and the supporting base therefor, said base being of sectional formation and having upper and lower rims at its outer edge, the end portions of the sections being widened and apertured, and clips overlapping the joints from between the sections and. fastenings comiecting the clips to the sections. 7

2. The means for use in connection with the sinking of a well shaft or the like, comprising the combination of a curb and a supporting base therefor, the latter having its outer edge downwardly flared and terminals ing in a cutting edge and having a vertical rim embracing the lower end of the curb said base being formed of sections whose end portions are widened and vertically aperturwl clips overlapping the joints between sections and having their outer edges adapted to touch the inner side of the lower end of the curb and. fastenings connecting said clips to the sections. 7

3. The herein described means for use in connection with the sinking of a well, shaft, or the-like thesame consisting of a curb eon1- prising courses each. course consisting of sections, the sections of one course arranged to break joint with the sections of the adj aeenl portions, the several curb sections being of like formation and having a tongue at one edge and a matching groove at the opposite edge and a base, the latter having a vertical rim to embrace the lower end of the curb and composed of like sections whose end. portions are widened and apertured, the outer edge portion of the base being downwardly flared and terminating in a cutting edge, clips overlapping the joints from between the sections of the base and having the space between. their outer edges and the inner edge of the vertical rim of a size to receive the lower edge of the curb, and fastenings connecting the clips with the sections of the base.

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