Latest Patents

Although David John McCullough currently holds no patents, his latest innovations include two notable designs for explosively actuated tools. The first design features a tool that is mountable to the end of a pole-like handle, allowing for remote manipulation and actuation. This tool is designed to drive a fastener into a substrate by pushing the forward end of a barrel against the substrate, which loads and releases a firing mechanism to fire the charge. A safety lock device is incorporated to prevent accidental firing unless the tool is oriented in a vertical or near-vertical position.

The second design focuses on the firing mechanism of an explosively actuated tool. It includes a cocking rod and sear that work together to entrain the firing pin, which can be released by rotating the sear. This mechanism is subject to axial and rotational bias from a coil spring, ensuring reliable operation during use.
