Latest Patents

One of Harm's latest patents, titled "Municipal Casting Frame and Method of Manufacturing Same," introduces a novel municipal casting frame equipped with cast nut retainers. This design allows the frame to operate effectively with or without a bolt-down cover. The frame features one or more bolt holes that are dimensioned for the easy passage of cover bolts. It also incorporates a cast nut retainer on its undersurface, designed to securely receive a nut. Notably, the retainer can accommodate a nut with protrusions enabling a snap-fit or through a wedging interaction with friction.

The innovative methodology outlined in this patent includes several critical steps: providing a core that matches the shape of the bolt hole and the cast nut retainer, casting the frame in a mold around this core, carefully removing the cast frame from the mold, and finally, extracting the core from the cast frame. This process also allows for convenient insertion of a nut into the retainer aligned with the bolt hole, enhancing efficiency in manufacturing.
