“Voracious Mouth,” or “Voracious,” or “Mouthy” as I usually refer to it, is the second in the series that started with “Impatient Hand.” It utilizes the same 30mm anti-tank rounds, this time as teeth.
Voracious Mouth has three overlapping mechanisms which combine to give it a complicated motion that comes close to a kind of “ordered randomness.” The first motion is an oscillating, “massaging fingers” motion of the individual teeth, which is accomplished with a large multi-lobe cam which is co-axial with the main open/close joint of the mouth. The second motion is the main open/close movement, which is accomplished with a rotary-to-linear-oscillating mechanism and actuated from below by way of connecting arms. And the third is a pneumatically powered, sudden SLAM, from full open to full shut. This happens once every eight cycles of the main open/close. Because Mouthy is intended for a gallery setting, or even someone’s home, and compressed air cannot reasonably be expect to be available in these settings, Mouthy features a compressor and full pneumatic system on-board. The entire sculpture is powered by one regular wall-socket power plug.
