Workers and an olive oil press, San Fernando, Los Angeles, ca.1900

Photograph of workers and an olive oil press, San Fernando, Los Angeles, ca.1900. Two workers are working on the filtering process in the olive mill. The mill is directly behind the area the men are working at. Filter plates (screens?) are lifted by hydraulic or mechanical lifts to a position where the men can load the plates underneath the end of a funnel out of which the olive oil will flow. At the bottom of the filtering plates is an outlet where filtered olive oil is allowed to flow into a bucket.
