AN impact recorder which registers the amplitude or the shocks encountered and the time at which they occur on any given journey, should prove of value to those operators who handle traffics that may be particularly susceptible to damage in transit. From the graph produced by the recorder, it should be possible to make a close check on the circumstance which brought about any damage which the goods may have suffered.

known as the Co-net. its dimen sions are 13 in. by 9i in. by 4 in. It is affixed to a vehicle under observation, the recording tape being loaded in a similar manner to a photographic film.
Immediately before the start of a journey the clock in the instrument is fully wound. The rate of travel of the tape is 1 in. per hour.
When an iinpact occurs the mobile mass in the recorder is displaced along guide rails in the direction of travel. Such displacement is registered by a trace left by a stylus on the tape. The graph so produced will serve as a complete record of the amplitude and the time of all shocks occurring during a period of 10 days.
