  • Patent number: 5035174
    Abstract: Improved apparatus for extracting juice is disclosed. The apparatus disclosed provide a novel safety switch arranged such that the apparatus may be operated only when fully closed, thereby precluding injury to the operator or damage due to objects being placed in the path of the downwardly descending squeezer. In a preferred embodiment the juice extraction cycle is carried out automatically by means of limit switches, once the safety switch enables the motor. Embodiments are disclosed wherein the limit switches which govern the extraction cycle operate by determining the amount of pressure placed on an object, the level of pressure being adjustable, thus allowing the complete and efficient squeezing of objects of different sizes and firmness. Also disclosed are embodiments incorporating a feeder tube and actuation device whereby the juice extraction apparatus is automatically fed.
