Among his latest inventions is the Adjustable Dual Bit Drilling Machine. This hand-held automatic drilling machine features an expandable locating collet or locating pin, along with a pair of adjustably mounted drill bits that allow for simultaneous drilling of spaced-apart openings in a workpiece. The machine is equipped with a rotary drive motor for the drill bits, a first drive assembly for activating the expandable collet, and a second drive assembly for advancing the drill bits into the workpiece. An adjustable dashpot controls the force applied to the drill bits, thereby regulating the feed rate. Additionally, a bi-stable control valve initiates the drilling cycle and sequentially activates the drive assemblies, while a full depth sensor manages the control valve's state.
Another notable invention is the Peck Feed Drilling Machine, which incorporates a pneumatically operated vane motor and peck feed components. This machine drives a conventional drill bit through a speed-reducing gear train. The peck feed assembly consists of multi-state shuttle valves that work in conjunction with a drilling feed piston, a peck piston, and a clutch assembly to incrementally advance and fully retract the drill bit for peck drilling. The design also includes a dashpot for adjusting the feed rate, a second dashpot for slowing the drill bit during breakthrough, and a threaded mechanism for depth adjustment.
