Abstract
Abstract Apparatus for drilling horizontal holes includes a frame for holding a drill, and the frame is supported by a single wheel adjacent to the drill and dual wheels at the opposite end of the frame from the drill. A cable system is utilized for moving the drill inwardly toward the work and outwardly away from the work by a single operator. A single operator can also move the frame as required at the work site. Multiple drills may also be secured to the frame, so that a plurality of holes may be drilled substantially simultaneously.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
186 words
Horizontal drilling apparatus comprising, in combination: frame means for supporting a drill, including a first frame member, a second frame member movable relative to the first frame member to vary the length of the frame means; a single wheel secured to the frame means and movable relative to the frame means vertically upwardly and downwardly; a pair of wheels secured to the frame means remote from the single wheel and movable relative to the frame means vertically upwardly and downwardly; drill means, including a drill disposed beneath the frame means, movable on the frame means for drilling beneath the single wheel; thrust means secured to the frmae means adjacent to the pair of wheels for providing longitudinal stability while the drill means is drilling, including a bracket, and a wheel secured to the bracket and rotatable in the horizontal plane; and winch means secured to the frame means, including first winch means connected to the drill means for moving the drill for drilling beneath the single wheel, and second winch means connected to the drill means for withdrawing the drill from drilling beneath the single wheel.
Claim 2
Dependent Claim
186 words
