  • Publication number: 20020008130
    Abstract: A fish tape has a galvanized wire core wrapped by a twin-ribbon stainless steel sheath. The fish tape is flexible enough to be convenient to handle and store in a coil while still being stiff enough to fish through a conduit. A driver may be used to push or pull the fish tape. The driver has a housing with drive and pressure rollers therein for engaging the fish tape. The drive and pressure rollers each have curved and flat grooves for engaging a fish tape. The drive roller is driven by first and second right angle gears from a drive shaft which is connectable to the chuck of a hand drill. The drive shaft is arranged to be parallel to the fish tape. The driver housing has a slot for receiving the fish tape by moving the tape perpendicular to the length of the tape. A retainer is movable to open and close the housing slot.

  • Patent number: 6148482
    Abstract: A grip for a tool handle or other surface intended for gripping by a user, may be provided by a durable, expanded elastomeric material. Formation of the grip, and installation thereof on a handle may be effected to provide pre-loading of a normal force against the handle, requiring substantially less normal force by a user on order effect frictional engagement of a handle by the grip. The grip may also be formed to provide micro-pressure along ridges impressed into the hand of the user alternating with cavities in a surface of the grip for receiving intrusions of the hand. Thus, mechanical engagement, rather than strictly frictional engagement may be effected. Grips made in accordance with the invention have been demonstrated to provide sufficient engagement with a hand and a tool handle to permit a user to apply the maximum physical force available from the user.
