Abstract: A latch apparatus for use with gates includes a latch bracket and a latch bar which removably engages and is locked to the latch bracket. The latch bracket includes a plurality of inclined slots which accept pins mounted on the latch bar and a catch member which is spring loaded to bear downward on the top portion of the latch bar when the latch bar is engaged in the latch bracket. To release the latch bar from the latch bracket, the catch member is swung away from the latch bar and the latch bar lifted so that the pins slide out of the slots in the latch bracket.

Abstract: An apparatus for detecting and indicating the motion of electric motors includes a voltage sensing module which can be connected to the power terminals of any known type of electric motor and a display module. In the primary embodiment of the invention the voltage sensing module senses the applied or self-generated voltages present between the motor windings, and when no voltage is present, the display module provides an output which may be an electrical signal, or a visual, tactile or audible display. The apparatus is inherently reliable and fail-safe. A failure of components within the apparatus causes a display module output indicative that the motor is running when in fact it is stationary.
