A belt drive configured to cooperate with a drive mechanism is disclosed. The belt drive includes a drive belt pulley reciprocally coupled to the drive mechanism such that the drive mechanism reciprocally translates between a power stroke and a return stroke, a driven pulley reciprocally coupled to the drive belt pulley via a drive belt such that the drive belt include a plurality of asymmetrical drive teeth configured to cooperate with a plurality of asymmetrical driven teeth disposed on the driven pulley, and an engagement mechanism disposed substantially adjacent to the drive belt and the driven pulley such that the engagement mechanism is configured to cooperate with the drive belt during the power stroke, and the drive belt substantially disengages the driven pulley during the return stroke. |
