Abstract
The can crusher herein is a pedal, and optionally arm powered, safe, can folding crusher which is vertically hopper fed. An optional flywheel stores mechanical energy during periods of non-maximum power demand to enable the crushing process to proceed with an even application of power. The form of the can folding crusher is that of an exercise bicycle having a horizontal ram which engages cans in a first stroke to prepare the can to be creased into a folded relationship, and in a second stroke in which the folding crushing occurs. The exit chamber is barely the diameter of an adult finger, and is designed to have a length which prohibits both adult and child fingers and hands from reaching any point near the crushing chamber. The feed hopper is adjustable for a variety of lengths of cans, and the seat is adjustable to accommodate a wide variety of human power providers.
