Abstract: A locking device for a tool, such as a ratchet wrench, having a jointed drive head which may be situated in a series of angular positions relative to a handle, and which has means for temporarily holding the drive head of the tool at a predetermined angle with respect to the handle. The tool includes a spring-biased locking element disposed in the handle and which may be either engaged with, withdrawn from, or disengaged from the drive head. In the engaged position, the tool drive head is locked in place by the locking element. In the withdrawn position, the locking element is withdrawn from the head, and held away from it by the user to permit continuous changes in the angular relationship between the handle and the drive head. Finally, in the third orientation, the locking element is withdraw from the head and secured in a temporary holding position, allowing continual changes in the angular relationship between the handle and the head without the need for the user to continually hold the locking element.

Abstract: An articulating adapter for use with a set of socket wrenches for connecting a socket to a socket drive. The adapter includes a first drive section having a square drive at one end and a skirt section at the other end. The skirt defines a cavity. There is a bias spring seated in the cavity and held in place by a pivot pin which extend across the mouth of the skirt section. The adapter includes a second drive section within the skirt of the first drive section. The second drive section has a square drive at one end and a substantially round base at opposite end. The round base is pivotally seated in the skirt cavity. The round base has a substantially oblong bore therethrough. The pivot pin extends through the bore to allow the second drive section to articulate approximately 360.degree. within the skirt. The pivot pin, however, drives the adapter by engaging the sides of the bore when rotated.

Abstract: A socket wrench and ratchet attachment, including a wrench housing, a wrench handle that threadedly engages within the housing, the housing having an opening therein, into which a socket wrench or ratchet may snugly insert, and be bound into position for usage, upon turning of the handle into an engaging position. The handle has a series of stepped down extensions, that matingly fit within a bore and counterbore formed within the wrench housing, to provide for there mating engagement, when locking a socket wrench or ratchet into a position of utility.

Abstract: An adjustable hand tool comprising an integral multi-sized socket tool, including a drive handle, and a multi-tiered drive mountable to said drive handle, said multi-tiered drives providing either a series of tiers of drives all extending concentrically from one end of the drive, or said drives being provided to either end of the tool, and capable of being shifted within the drive to provide for a drive of one dimension upon one of its ends, and a drive of a different dimension upon the opposite end, and said tiered drives being shiftable within the multi-tiered drive to provide for exposure at either end. The various drives may be of rounded shape, so as to function in a manner similar to a universal joint, while the handle is manipulated for turning of its drive, as when used for tightening or loosening a bolt. The ratchet portion of the drive may include locking means, so as to lock the ratchet head and socket relative to its handle, once adjusted into an operative position.
