ABSTRACT:
An accelerometer has a single pendulum-type acceleration sensitive element, the movement of the pendulum moving a pointer through a gear arrangement such that scale graduations on a face of the instrument may be linear or of other character. Auxiliary pointers are provided so as to indicate the maximum positive and negative values of acceleration experienced by the instrument, maintaining always the highest magnitude reading attained. The recording auxiliary pointers are manually resettable from outside the instrument.
