ABSTRACT:
When using cable tool water well drilling machinery, referred to as a spudder, during drilling operations, the simultaneous operation of this water well drilling accessory is undertaken periodically, to drive water well casing pipe sections down below ground level. The basic component of this accessory, in a selective number of components, is a reciprocally guided hammer-head-ram integrally formed with both an axially aligned cylindrical chamber having a bottom entry to pass down over the top of the uppermost water well casing pipe section and slidably continue on down to surround a top portion of this pipe section, and another in line axially aligned cylindrical chamber having a bottom entry that will not pass over the top of the uppermost water well casing pipe section, but will allow passing of a drill bit and an overall drill string, other debris removing cylindrical units, such as a bailer, and their respective supporting and operating cables; and also there is an axially aligned impact transferring shoulder structure located where these two in line axially aligned cylindrical chambers meet one another, and this basic component is selectably joined with others: an interconnecting subassembly; a supporting and operating cable subassembly, inclusive of a cable path changing mechanism; and power source to operate the supporting and operating cable subassembly inclusive of operating the cable path changing mechanism, which in turn causes the up and down movements of the reciprocally guided hammer-head-ram, which then is driving water well casing pipe sections.
