Title: Innovations by Gary R. Sprague
Introduction
Gary R. Sprague is an accomplished inventor based in Rock Hill, SC (US). He has made significant contributions to the field of pneumatic brake actuators, holding 2 patents that showcase his innovative designs and engineering expertise.
Latest Patents
One of his latest patents is titled "Brake actuator and method of forming the same." This invention features an improved diaphragm-type pneumatic brake actuator that includes a flange case, a cover, and a flexible diaphragm. The diaphragm extends between the flange case and the cover, forming both a lower and an upper pneumatic chamber. A piston assembly is integrated into the cover, allowing for the movement of a spring between compressed and decompressed positions. Additionally, a spring guide is positioned between the cover and the piston assembly in the upper chamber to prevent corrosion by avoiding direct contact between the spring and the cover.
Another notable patent is simply titled "Brake actuator." This invention enhances the diaphragm-type pneumatic brake actuator by ensuring that the diaphragm is releasably secured to the piston. This design minimizes wear on the flexible diaphragm and improves the overall performance of the brake actuator. The diaphragm features a rib or lip that engages with the piston, creating a mechanical interlock that prevents spacing and frictional wear during actuation.
