Abstract

A drilling apparatus designed used to drill multiple holes in the bottom surface of an overhead surface. The drilling apparatus includes a lower frame member and an upper frame member longitudinally aligned thereover. The lower frame member includes two vertical uprights perpendicularly aligned and attached to a lower base mounted on caster wheels. A cable attached to a winch selectively lowers and raises the upper frame member over the lower frame member. Attached to the upper end of the upper frame member is a perpendicularly aligned horizontal support member. Mounted on the support member are two or more drill brackets that hold inverted drill motors each with a drill bit at a fixed location and at a fixed angle. At least one drill bracket includes a horizontal alignment flange surface that is used as an alignment surface for a laser placed on the support surface and aimed upward to the precise hole location on the overhead surface.

Dependent claims

A drilling apparatus of drilling holes on a raised elevated surface that is located at different heights above a flat support surface, the apparatus comprises:

a. a length adjustable frame that includes a lower frame member and an upper frame member, said lower frame member includes a plurality of wheels that enable said lower frame member to be rolled over a flat support surface, the upper frame member includes an upper end;
b. a support member attached and transversely aligned to the upper end of the upper frame member;
c. at least two drill brackets adjustably attached to the support member, each drill bracket configured to hold a drill in an upward extended position on the support member, at t least one of the brackets includes an outward extending flange surface that is vertically aligned under a center axis of a drill attached to the drill connected to the bracket;
d. an upward extending electric drill attached to each drill bracket;
and,
e. a means for longitudinally extending or retracting the upper frame member from the lower frame member.
