Title: **Marc Combette: Innovator in Powder-Actuated Tools**
Introduction
Marc Combette, an accomplished inventor based in Valence, France, has made significant contributions to the field of powder-actuated tools. With a portfolio of 12 patents, his innovations are centered on enhancing the efficiency and functionality of fastener-driving tools.
Latest Patents
Among his notable inventions are two groundbreaking patents. The first is a **Powder Actuated Piston Tool with Power Adjustment**, which introduces a mechanism for adjusting the power of a piston-type fastener driving tool. This design features a tube that is slidably positioned within the tool's barrel. The tube contains the driving piston and incorporates a radially inwardly extending flange at its breech end, which interfaces with an outwardly extending surface on the piston. The innovative means for axially moving the tube allows the distance from the flange to the firing chamber to be varied, enabling adjustments to the gas expansion chamber. This results in a customizable power level, allowing for greater control over the force exerted by the piston during operation.
The second patent is an **Offset Piston for Powder Actuated Tools**, which features a unique barrel assembly with two parallel, communicating bores. The design incorporates a piston with joined, offset portions, enabling one portion to slide in one bore while another portion operates in the other bore. This innovation allows for a more compact tool capable of setting long fasteners while ensuring continuous centering throughout the operation.
