ABSTRACT:
A diminishing arm toggle linkage has the work site within the toggle geometry and thereby provides exponential force enhancement. In preferred embodiments the mode of operation shifts on demand from a light-load-pivoting mode to a heavy-load-rolling element mode thereby easing operation and reducing friction and wear so as to provide prolonged durability and continuing dimensional accuracy. When the toggle linkage is embodied in a crimping tool an optional anti-reversing ratchet assembly prevents the tool from opening during use until a crimp is completed.
