Axle weight load indicator device
First Claim
1. An axle weight load indicator device for detecting a pre-set load limit on a motor vehicle axle with the capability of eliminating false signals during movement of the motor vehicle, said device comprising:
- (a) a permanent stop mounted on the axle to prevent further movement when contacted;
(b) a housing positioned on the motor vehicle to be in operable association with the permanent stop, said housing having an electrical switch associated therewith and a retractable probe, wherein the probe when used to detect the pre-set load limit extends from the housing a sufficient distance to contact the stop if the load limit has been exceeded and cause the electrical switch to complete an electrical circuit, yet said probe when not used retracts at least partially into the housing to ensure against false readings; and
(c) alarm means connected to the electrical switch to signal when a pre-set load limit has been exceeded.

Abstract
An axle weight load indicator device for mounting on a motor vehicle to detect when a pre-set axle weight has been exceeded. The device includes an electrical switch, an axle-mounted permanent stop and a retractable probe mounted in a housing which is operably associated with the electrical switch and permanent stop. When not in use, the probe is retracted into the housing to ensure that false signals are not emitted during movement of the motor vehicle. When operable, the probe is positioned to make contact with the permanent stop when a pre-set load limit has been exceeded. Continued loading causes activation of the electrical switch. The electrical switch trips an alarm to warn of the excess load.
