Abstract: Socket and ratchet wrench combinations having systems for positively locking the socket to the ratchet wrench are disclosed. The disclosed sockets have at least one circumferential axially aligned annular groove extending about their exterior surface with one or more openings in the side of the groove(s) for receiving sections on the ratchet wrench which cooperate with the socket's groove(s) to positively lock the socket to the wrench.

Abstract: Socket-type wrenches using a magnetic ratchet/clutch-type apparatus are disclosed. The apparatus preferably employs several pawls, as well as a ratchet-type wheel for engaging the pawls. The apparatus also utilizes the wrench's body which defines a chamber in which the wheel is received for rotation relative to the wrench body. The chamber also defines pockets for positioning the pawls adjacent the wheel to facilitate their movement between a drive position and a release position. In the drive position, at least one pawl is sandwiched between the wheel and a wall of the pocket to prevent the wrench body and the wheel from rotating relative to each other which enables a drive stroke to be made with the wrench. In the release position, the pawl is disengaged from the wheel which permits one to make a return stroke with the wrench. The apparatus further includes a ring magnet mounted on at least one side of the wheel for magnetically attracting the pawls to facilitate their movement into the drive position.

Abstract: Drive apparatus and method for converting linear motion to rotary motion and vice versa are disclosed. The drive apparatus includes a rack having a plurality of spaced first engagement members arranged single file in a first path and a sprocket having a plurality of spaced second engagement members arranged single file in a second path. The rack's engagement members engage the sprocket's engagement members to rotatingly drive the sprocket when the rack is driven and drive the rack when the sprocket is driven. In addition, either the rack's engagement members or the sprocket's engagement members have outer surfaces which are defined by a member selected from the group consisting of cylindrical bearings and reduced friction material. To operate the apparatus to drive a sprocket, a downstroke is made with the rack to move it as far as it can be moved in a first predetermined direction which rotates the sprocket in a desired clockwise or counter-clockwise direction.

Abstract: Drive apparatus and method for converting linear motion to rotary motion to rotatingly drive the driveshaft of a motor vehicle are disclosed. The drive apparatus includes a sprocket rigidly connected to a shaft and axially aligned thereabout. In addition, a moveable ratch for moving between first and second drive positions and having opposing first and second linear sprocket engaging drive segments is provided. The first linear drive segment of the moveable ratch engages the sprocket when the ratch is in its first drive position and the second linear drive segment engages the sprocket when the ratch is in its second drive position.

Abstract: A drive apparatus and method for continuously transmitting power to an axle to rotatingly drive the axle are disclosed. The drive apparatus includes a flexible ratch such as a flexible chain, belt, or cable, and cooperating first and second ratch engaging members for alternatively engaging the flexible ratch to continuously drive an axle. To operate the apparatus, one moves the first and second ratch engaging members in a first direction which causes the first ratch engaging member to engage and drive the flexible ratch which rotatingly drives the axle. One then reverses the ratch engaging members' direction of movement which causes the simultaneous releasing and engaging of the ratch by the first and second ratch engaging members, respectively, which continuously drives the axle.
