Abstract
A comb plate device for a passenger conveyor comprising a longitudinally extending mounting plate for mounting transversely of a conveyor, a comb plate pivotally mounted on the mounting plate about an axis parallel to the said mounting plate and fluid-sensing means to detect pivotal movement of the comb plate when in use on a conveyor.

A comb plate device for stopping a passenger conveyor upon detection of potentially damaging condition on the conveyor comprising a longitudinally extending mounting plate for mounting transversely of a conveyor, a comb plate pivotally mounted on the mounting plate about an axis parallel to the said mounting plate and fluid-sensing means to detect pivotal movement of the comb plate away from the conveyor when in use on a conveyor said fluid-sensing means comprising a detector positioned in a vacuum line to detect opening of an aperture in the fluid-sensing means on pivotal movement of the comb plate.
