Abstract: An impact tool (A) is disclosed which includes an arrangement of angularly disposed shanks which provide a mechanical advantage to the impact force. A first shank (10) provides a grip (12) held generally orthogonal by hand (14) of the user. A second shank (16) extends generally in a straight line to the arm (24) when the grip is held in the hand, and a third shank (18) extends from the second shank (16) at an angle and terminating in an impact head (20). The device thrusts generally forward with the arm and shoulder during impact with little or no wrist movement as encountered in the sense of a conventional handle. Control is afforded by the angle arrangement of the handle as well as increased force.
Abstract: A hammer having an improved head assembly. The hammer head assembly has a head portion, a shank portion, and a claw portion. The head portion has a front face having a triangular configuration. The head portion also has a horizontally oriented top wall and two side walls that converge downwardly toward their bottom ends where they meet. The center of the front face of the head portion lies on an axis that is perpendicular to the longitudinal axis of the handle and they intersect at the center of gravity of the hammer head assembly. The top end of the shank portion is flat so that the hammer can free stand on the surface. There is a rounded indentation between the shank portion and the claw portion so that it may be rested upon a block or cats paw for extra leverage. A T-shaped slot may be formed in the top end of the handle and it may have a related magnet for detachably capturing the head of a nail therein for hammering purposes.

Abstract: The magazine hammer has a hammer head (1) and a hammer shaft (2) running transversely to the latter. A guide channel (3) for guiding nails (4) from a nail magazine (5) runs in the longitudinal direction of the hammer shaft (2). The guide channel (3), in its end facing the hammer head (1), forms a deflection channel (7) for swinging round the nails (4) fed individually in their longitudinal direction. For this purpose, the deflection channel (7), on its lower side or its side remote from the hammer head (1), is provided with a passage slot (11) for the nail shank so that, in this area, a nail (4) fed individually in its longitudinal direction can swing about its nail head as a rotational axis into the desired setting position at the hammer head (1).
Abstract: Striking tools, heads and handles for such tools, and methods of manufacturing them. A tool head according to this invention employs a flange which extends from each side of the head between the forward and rear portions of the head. The portion of the head within the periphery of each flange is generally concave and narrows to form a web extending longitudinally in the striking direction to connect the forward and rear portions. The web may include at least one opening communicating between the two concave surfaces. The flanges increase the cross-sectional area and moment of inertia of the head relative to the striking direction and relative to the handle axis. The resulting head enjoys greater strength and resistance to translational forces, bending moments, deformation and potential failure. Portions of the handle extending through the opening in the head and thereby about portions of the head reduce the possibility that the head will leave the handle as the tool is being swung.
