(a) A fixed guard enclosing front and sides of platen with stock feeding slots too narrow to allow insertion of operator's fingers, or

(b) An interlocking gate guard connected with the operating mechanism in such a way that it will automatically protect the front and sides of platen during the power stroke, ensuring that the operator's hand cannot be caught by the platen, or

(c) A starting device which requires the simultaneous action of both hands of the employee or employees when two or more employees are operating the press, or

(d) A sliding or revolving table or other feeding device which does not require the operator's hands to be placed under the platen, or
