Title: Innovations of Douglas R Dole
Introduction
Douglas R Dole, based in Whitehouse Station, NJ, has made significant contributions to the field of engineering and design through his inventive spirit. With an impressive portfolio of 204 patents, Dole's work primarily focuses on innovations in pipe grooving technologies.
Latest Patents
Among his latest patents are the "Cams for pipe grooving device" and the "Cam grooving machine." The first patent outlines a device designed to form circumferential grooves in pipe elements using multiple geared cam bodies mounted on a carriage. This system utilizes a fixed pinion that engages with the gears, allowing for smooth rotation and precise groove formation. The cam surfaces feature a region of increasing radius, with potential for a constant radius, ensuring accuracy in the groove's dimensions. In addition, the second cam surfaces assist in limiting the flare of the pipe element.
His "Cam grooving machine" patent describes a device for cold working pipe elements that incorporates multiple cams, each meshing with a pinion. This innovative design allows for the precise alignment of regions of reduced radius in each cam surface with gaps in their traction surfaces, ensuring efficient insertion and removal of pipe elements during the grooving process.
