Title: The Innovations of Charles P. Coughlin
Introduction
Charles P. Coughlin is a notable inventor based in Chelsea, NY (US). He holds a total of 4 patents that showcase his contributions to engineering and technology. His work primarily focuses on advancements in bearing constructions and test probes.
Latest Patents
One of Coughlin's latest patents is the Linear Compensating Bearing. This invention features a bearing construction that interposes coils of one or more coil springs between bearing surfaces. In one embodiment, a bearing coil spring is wrapped around a shaft several times. The bearing coil spring may be freely mounted on a more substantial race coil retainer centered on the shaft. In another embodiment, toroidal coil springs separated by disc races extend circularly about the shaft. In linear bearing construction, the bearing coils are in planes parallel to the line of shaft movement. Other embodiments involve disengageable shafts with complementary centering end-faces that accommodate misalignment through the yieldable action of the bearing spring coils. Additionally, shafts and housings may have non-circular cross-sections, enabling interference fit and positional control.
Another significant patent is the Coaxial Probe. This coaxial test probe employs a flexible inner conductor that buckles upon the application of an axial load and is housed within a conductive outer sheath. The inner probe includes an insulating spacer that forms a recess applied to the protruding end of the inner conductor, allowing buckling to occur within the recess. A plurality of adjacent probes are mounted on a test fixture at opposing angles to facilitate automatic interrogation of closely spaced contact pads.
