His machine accepted a coin and then dispensed holy water . When the coin was deposited, it fell upon a pan attached to a lever . The lever opened a valve which let some water flow out . The pan continued to tilt with the weight of the coin until it fell off, at which point a counterweight snapped the lever up and turned off the valve . </P>
