Abstract: A stem shaft handle has a handle body and a gearless ratchet assembly having a threaded cylindrical drive head disposed within an inner cavity defined by the handle body. The threaded cylindrical drive head connects the gearless ratchet assembly to a chuck assembly having a cylindrical chuck body concentrically disposed within an outer sleeve. The cylindrical chuck body has an outer surface which closely aligns with the outer sleeve in a key-and-lock style geometric alignment. The outer surface of the cylindrical chuck body has at least one biasing locking protuberance, and the outer sleeve defines adjacent notches around at least one nodule geometrically configured to operatively engage the at least one biasing locking protuberance in a locking arrangement. Upon a rotation of the stem shaft handle relative to the outer sleeve, the outer sleeve impinges the biasing locking protuberance until the biasing locking protuberance snaps into the locking arrangement between.

Abstract: A stem shaft handle has a handle body and a geared ratchet assembly disposed within an inner cavity defined by the handle body. The threaded cylindrical drive head connects the geared ratchet assembly to a chuck assembly having a cylindrical chuck body concentrically disposed within an outer sleeve. The cylindrical chuck body has an outer surface which closely aligns with the outer sleeve in a key-and-lock style geometric alignment. The outer surface of the cylindrical chuck body has at least one biasing locking protuberance, and the outer sleeve defines adjacent notches around at least one nodule geometrically configured to operatively engage the at least one biasing locking protuberance in a locking arrangement. Upon a rotation of the stem shaft handle relative to the outer sleeve, the outer sleeve impinges the biasing locking protuberance until the biasing locking protuberance snaps into the locking arrangement.

Abstract: The present disclosure provides for a stem shaft handle adapted to grasp a stem shaft. The stem shaft handle includes a handle body and a chuck assembly removably connected to the handle body. The chuck assembly includes a cylindrical chuck body having an outer surface with at least one biasing locking protuberance disposed within an outer sleeve defining at least one nodule geometrically configured to fittingly engage the at least one biasing locking protuberance in a locking arrangement. In a preferred embodiment, the cylindrical chuck body has a concentrically disposed cylindrical plate which defines at least one nonconcentrically disposed aperture adapted to receive at least one nonconcentrically disposed retention member in a lock and key style geometric alignment and is removeably connected to the handle body. In other preferred embodiments the handle body defines an inner cavity having a geared ratchet assembly or a gearless ratchet assembly disposed therein.

Abstract: A device has a shaft adapted to be rotated. The device has a handle adapted to be operatively coupled to the shaft and adapted to be grasped by a user and twisted in a first rotational direction, turning the shaft. An assembly is provided between the shaft and the handle. The assembly has lower end, formed with an opening and jaws, coupling the assembly to the shaft. The assembly has an upper end attached to the handle. In this manner the assembly rotates with the handle. The assembly has a nut rotatable with respect to the upper end and the handle. A threaded interface is provided between the nut and the jaws. In this manner rotation of the nut with respect to the upper end and the handle will radially constrict and extend the jaws. Further in this manner the handle will coupling and uncouple with the shaft.

Abstract: Two similarly configured upper brackets are each formed of an inverted L-shaped fixed component above and an L-shaped adjustable component below. Each fixed component has a horizontal leg above and a vertical leg below. Each horizontal leg has laterally spaced vertical support holes. Each vertical leg has elevationally space adjustment holes. Each adjustable component has a horizontal leg below and a vertical leg above. Each vertical leg has laterally spaced horizontal support holes adjacent to the horizontal leg. Each vertical leg has elevationally spaced adjustment holes. Each leg is sized to allow the vertical leg of each adjustable component to slidably receive the vertical leg of an associated fixed component to align the holes in the legs selectively with adjustment elements extending through aligned holes. The horizontal leg of each adjustable component has an upper surface to provide an upper support surface for an air handler.
