ABSTRACT:
A printing press blanket gauge for measuring the thickness of blankets used in printing presses consisting of a casing containing measuring and indicating means such as a dial test indicator, the casing having projecting from it two pointed probe members capable of penetrating a printing blanket without damaging it and making electrical contact with a metal surface below the blanket, there being arranged between the pointed probe members a probing means connected to the dial test indicator and within the casing a source of electricity connected to the probe members through a lamp or other signalling means, the arrangement being such that when both the pointed probe members and the probing means are pressed against the surface of a printing blanket the pointed probe members pass through the blanket and are electrically connected externally of the casing through the metal surface beneath the blanket thus causing the lamp to illuminate and the dial test indicator to give a direct indication of the thickness of the blanket.
