Concrete Slab Rebar Hole Dowling Cart
The present invention is a rebar hole doweling cart that pivotally holds an electric hammer drill near the ground to tap a hole and place the bit in a set aimed direction, and grips engages the ground to produce a manually-generated leveraged pushing force to drill rebar or dowel holes into a slab of concrete to construct or repair sidewalks, driveways, roadways, curbs, floors and the like. The cart has a frame, wheels, an elongated handle, a nose plate and a drill mounting assembly. The wheels position the cart and drill in front of the concrete slab. The elongated, upwardly extending handle is manually pushed or stroked forward to rotate the nose plate into gripping engagement with the ground and advance the drill bit forward. The drill mounting assembly simultaneously counter-rotates during the stroke to maintain the drill bit in its set aimed direction as the bit advances into the slab to form the hole.
