Description

Figure 54. Richter mounting with messenger and pump brake for slowing reversing action. With the earlier models used by Doflein, the mounting would flop overtoo quickly and jar the mercury column sufficiently to cause its separation. To slow down the reversing motion, a piston pump mechanism was installed on themounting. This mounting was employed by Doflein off the coast of Japan in 1904.
