We have developedour own Eve's rocker. Basically this is a baby's cot which rocks to and fro, covering an angle of 70 in so doing. It has12 respiratorycycles per minute. For those who are interestedin the mechanicalside, it is driven by a one-third brake horsepowerinotor giving 1425 revolutions per minute, which is reduced by suitable gearing to 12 revolutions per minute. From this gearing a wheel with an eccentricallyattachedarm rocks the cot to and fro.
