Latest Patents

One of Clifton's latest patents is the Dual Durometer Twist-On Connector. This invention features a twist-on or wire-nut electrical connector that includes a rigid, electrically insulative upper body and a flexible, elastic, electrically insulative lower skirt. The design incorporates a coil spring within the body for gripping wires, allowing for the insertion of a larger number of wires or larger-sized wires into the connector. The flexible skirt deforms to fit more easily within crowded junction boxes or high-density wiring environments. Unlike prior art twist-on connectors, the lower skirt is directly attached to the open end of the polymeric body, enabling greater application of torque to the rigid body. The preferred embodiment utilizes polypropylene for the upper body and a styrenebutylene compound or an olefinic thermoplastic vulcanizate for the lower skirt, constructed through multicomponent injection molding.

Another significant patent is the Coated Abrasive Back-Up Pad with Metal Reinforcing Plate. This invention comprises a layer of resiliently compressible foam and a generally rigid fiber-reinforced polymeric backing plate. The design features a circular array of openings in the backing plate for attachment to a drive mechanism, along with a flexible adhesion layer fixed to the opposite surface of the foam layer. A metal reinforcing plate is included between the backing plate and the foam layer to prevent screws from breaking through during use. The adhesion layer is radiused around access holes to ensure consistent grinding pressure across the surface.
