Abstract:
1. A device useful for drilling holes in the earth comprising: a) a horizontal frame member having a first end portion and a second end portion; b) a vertically inclined tubing casing having a first end portion, an open second end portion, a length dimension, and a hollow interior portion, wherein said first end portion of said vertically inclined tubing casing is attached to the second end portion of said horizontal frame member, said vertically inclined tubing casing further comprising a hole disposed through it along its length, said hole having an axis, wherein the axis of said hole is substantially perpendicular to the length dimension of said vertically inclined tubing casing; c) a vertically inclined brace portion having a first end portion, a second end portion and a length dimension, wherein said first end portion of said vertically inclined brace is attached to said horizontal frame member at a location between said first end portion of said horizontal frame member and said second end portion of said horizontal frame member, such that the length dimension of said vertically inclined brace portion and the length dimension of said vertically-inclined tubing casing are substantially parallel to one another; d) an adjustable height support having a first end portion, a second end portion, a length dimension, and a length dimension axis, wherein said first end portion of said height support and at least a portion of the length of said height support is slidably disposed within said vertically inclined tubing casing, said height support further comprising a plurality of holes disposed through it along its length, said holes each having an axis, wherein the axis of said holes are substantially perpendicular to the length dimension of said height support; e) a two-axis hinge which is hingedly connected to said second end portion of said height support, said two-axis hinge having a degree of freedom which enables its rotational movement about said length dimension axis of said height support; f) a substantially linear vertical guide outer member having a first end portion, an open second end portion, and a length dimension, wherein said first end portion of said vertical guide outer member is pivotally connected to said height support by means of said two-axis hinge such that said vertical guide outer member is given a sufficient degree of freedom to rotate rendering its second end portion capable of striking out an arc which intersects said adjustable height support at a point along the length of said height support; g) a hydraulic ram having a hydraulic oil inlet, a hydraulic oil outlet, a length dimension, a first end portion disposed at the end of its stationary portion, and a second end portion disposed at the end of its moveable portion, wherein said hydraulic ram is attached to said vertical guide outer member such that said length dimension of said hydraulic ram and the length dimension of said vertical guide outer member are substantially parallel to one another; h) a substantially linear vertical guide inner member having a first end portion, a second end portion and a length dimension, wherein at least a portion of said first end portion of said vertical guide inner member is slidably disposed within said vertical guide outer member i) a drilling head attached to said second end portion of said hydraulic ram and said second end portion of said vertical guide inner member; j) an engine, wherein said engine is mounted to at least one of said horizontal frame member, said vertically inclined tube casing, or said vertically inclined brace portion; k) a hydraulic pump in effective mechanical contact with said engine such that said engine supplies motive power to said pump; l) a hydraulic oil reservoir; and m) means for providing hydraulic fluid under pressure from said hydraulic pump to said hydraulic ram.
