Timothy E. Florian has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A wrench has a roller motion transmission mechanism that changes reciprocating motion of a driving member to unidirectional rotational motion of a driven member. The wrench has a head with a cylindrical inside wall surrounding a body with a plurality of ramps inclined toward the cylindrical inside wall. A wedging member comprising a cylindrical roller engages each ramp and the cylindrical inside wall of the head. A cage anchored to the body retains the wedging members in contiguous locations relative to the ramps and the cylindrical inside wall of the head. Retainers connected to the cage bias all of the wedging members into engagement with the ramps and the cylindrical inside wall of the head.

Abstract: A wrench has a roller motion transmission mechanism that changes reciprocating motion of a driving member to unidirectional rotational motion of a driven member. The wrench as a head with an inside cylindrical wall surrounding a body with a plurality of protrusions. Each protrusion has a ramp inclined toward the cylindrical wall. A wedging member comprising a cylindrical roller engages each ramp and inside cylindrical wall of the head. A cage anchored to the protrusions retains the wedging members in engagement with the ramps and the inside cylindrical wall of the head.
