Abstract
A mallet is described that has at least one cleft, in such a structure that the stress wave created during impact has longer travel way than the length of the mallet as measured along the impact line. This mallet induces longer-lasting and weaker stress wave(s) in the anvil as compared to a solid mallet having the same outer dimensions and more or less the same weight. The Cleft-Mallet increases the effectiveness of the strike, while decreasing the stresses in the anvil.
Claims21
A cleft-mallet comprising:
- at least three segments;
- and
- at least one cleft separating the segments.
A cleft-mallet comprising:
- an outer tube having a first longitudinal axis;
- an inner element arranged within the outer tube, the inner element having a second longitudinal axis;
- a radial element functionally connected between a first end of the outer tube and a first end of the inner element;
- a cleft separating the inner element, the outer tube, and the radial element from each other;
- and
- wherein at least a part of the outer tube is a longitudinal segment configured for linear stress waves and/or torsion stress waves;
- wherein at least a part of the element is a longitudinal segment configured for linear stress waves and/or torsion stress waves;
- and
- wherein at least a part of the radial element is a radial segment configured for shear stress waves.
