First Claim
1. Apparatus for indicating when the acceleration of a device in a selected direction exceeds a predetermined value, comprising, in combination:
- (a) a housing having a longitudinal axis;
(b) switch means mounted in the housing, including an electrically conductive acceleration responsive mass movable in a direction aligned with said longitudinal axis, and a plurality of electrical contacts disposed at one end of said switch means for bridging contact by said mass when moved to said one end;
(c) a light emitting diode mounted in said housing and visible from without said housing;
(d) a disabling switch mounted in said housing and operable from without said housing;
(e) a battery removably mounted within said housing;
(f) means connecting said battery, said switch means, said diode, and said disabling switch in a series circuit;
(g) a support bracket having a base surface and support legs extending from said surface;
(h) means carried by said legs for engaging sides of said housing in adjustable supporting relation about a pivotal axis orthogonal to said longitudinal axis;
(i) Velcro loop and hook means for removably fastening said base surface to a generally flat mounting portion of the device, with said pivotal axis generally horizontal and said directions in alignment;
(j) and means fixing the adjusted position of said housing about said pivotal axis to determine the acceleration required to move said mass into bridging engagement with said contacts.

Abstract
A device to be used in connection with an automotive vehicle for indicating rates of acceleration above pre-set thresholds so that the vehicle operator may change such rate in a fashion to reduce fuel consumption. The device includes a box-like housing containing a mercury switch having two electrodes located at a first end thereof and which are adapted to be bridged when the mercury mass moves under the influence of acceleration forces. These electrodes are connected in a series circuit with a source of electrical potential and an indicator means such that a signal is given when and if the vehicle is accelerated at a rate above an adjustable, pre-set level.
