Double strike
the six-link swivel chain is the so-called Stephenson chain
green: four-link chain; red: two punch; hatched: three-hinged links
The term two-stroke on the one hand in the truss -Statik, on the other hand, in the transmission -hand technique:
In a framework, the two members of a three-part field or compartment , the third member of which is formed by the subsoil, another mostly solid component or a frame , form the two-tier.
The expansion of an inevitable coupling gear with a two-stroke (two articulated links) results in a likewise inevitable, higher-link coupling gear. In this way, for example, the four-link swivel joint chain is turned into the six-link chain (see figure opposite). "Depending on whether the two shock at the opposite links of the four-bar chain or to the adjacent links is connected, the two 6-membered rotary joint chains are formed with adjacent three articulated members ( Watt's chain ) and having opposed three articulated members ( Stephenson'sche chain ) ." If the two-stroke connected outside or inside the four-link chain is insignificant. "The structures of these so-called alternating forms are identical."
