<p>An adjustable fulcrum hammer (20, 100) with a handle (22, 102) having a grip (24, 106) at one end, a head (26, 104) fixed about the other end, a fulcrum rod (32, 112) extending into the hollow interior of the handle through a bore (34) in the head, and elastomeric member (36, 152) on the end of the rod remote from the head for contacting a fulcrum surface, a set screw (40) extending the handle between its ends for locking the fulcrum rod in any desired position and a spring (46) mounted within the handle for urging the rod outward. In another embodiement of the present invention, a locking mechanism (124) is integrally provided by cooperating threads (126, 127) which disengage and allow for reciprocable movement when the fulcrum member is rotated a quarter-turn.</p> |
