Abstract: This invention relates to a portable, wheeled cooler apparatus having a (1) cooler chest assembly; (2) support wheel assembly on which the cooler chest assembly is mounted; and (3) a combination handle and lock assembly connected to the cooler chest assembly to act as a lock in an enclosed condition and as a handle in a transport condition. The cooler chest assembly includes a support container member with a removable enclosure lid member mounted thereon. The support wheel assembly is operable in an upright condition of the cooler chest assembly to restrict lateral movement thereof as having support wheel members out of contact with a support surface. The cooler chest assembly is pivotal rearwardly out of contact with the support surface for ease of movement on the wheel members.

Abstract: A screwdriver or the like has a shank adapted to hold any one of a number of double ended bits together with a handle for the shank having storage slots for those bits not being held in place by the shank. A split ring, rotatable on the stem of the handle, holds the stored bits against displacement until the ring is rotated to place the space between the ends of the ring into alignment with a selected slot.
