• "The common central vessel from which the sparge-arms radiate is mounted in such a manner that it rotates automatically when a stream of water is admitted, so that a constant fine spray covers the whole tun when the sparger is in operation."
• "The mash-tun is also provided with a stirring apparatus (the _rakes_) so that the grist and liquor may be intimately mixed (D), and an automatic sprinkler, the _sparger_ (fig. 2, B, and fig. 3), which is employed in order to wash out the wort remaining in the grains."
• "After this, "taps are set" -- _i. e._ communication is established between the mash-tun and the vessel into which the wort runs -- and the sparger is started."
