Electric timing bench and control box for the same

摘要

An automatic, accurate and inexpensive timing bench, able to be purchased and used by any amateur. The bench consists of a conventional chronograph wristwatch (2) and a control box (1) provided with a housing (12) for the chronograph and a transparent cover (17). The box (1) further includes input ports, for receiving electric signals originating from timing cells, and electromagnets (51, 52) for automatically pressing the push buttons (8, 9) of the chronograph as a function of said input signals. As a result of auxiliary electric ports on each box, several of these boxes can be coupled in cascade to form a more complex timing bench.
