    Abstract: A tool for bending an elongated workpiece includes a shaft having a first shaft portion and a second shaft portion, and a coupling assembly coupling the first shaft portion and the second shaft portion. The coupling assembly has a locked configuration in which the coupling assembly inhibits movement of the first shaft portion relative to the second shaft portion and an unlocked configuration in which the coupling assembly permits movement of the first shaft portion relative to the second shaft portion. The tool also includes a shoe coupled to the second shaft portion. The shoe has a curved bottom portion and a hook configured to hold the workpiece against the curved bottom portion. The curved bottom portion is engageable with the workpiece to bend the workpiece.

    Abstract: A torque wrench including a head, a handle, a primary beam, a secondary beam, and a torque adjustment mechanism. The primary beam couples the head and the handle for co-rotation about the rotational axis and the primary beam includes a first end adjacent the head and a second end adjacent the handle. The secondary beam is coupled to the head for rotation with the head about the rotational axis and the secondary beam is movable relative to the primary beam and the handle. The torque adjustment mechanism adjusts a torque setting of the primary beam relative to the secondary beam. The torque adjustment mechanism includes a thumb adjustment wheel that a user rotates about a first axis to adjust the torque setting by moving the second end of the primary beam relative to the handle along a second axis offset from the first axis.

    Abstract: Various reusable respirator designs are shown. In one example, a reusable respirator includes an inhalation pathway with a conduit extending from the exterior of the respirator into the nose piece allowing users to receive air directly into an inner sealed zone around a user's nose and mouth. The inhalation pathway includes a vent opening such that the inhalation pathway also directs air into a facemask zone, between the nose piece and an outer seal reducing/preventing shield fogging during inhalation. In another example, the respirator includes cartridge attachment lobes each having a different size and shape. A filter cartridge assembly can only be aligned with the lobes in one orientation, creating a robust connection. In another example, a storage bin for a reusable respirator includes a one-way film placed underneath a plurality of perforations allowing gases and moisture to escape the bin while limiting the ingress of other gases or particles.
