Abstract: A soap press for compressing soap pieces and forming a bar therefrom. The press comprises a press chamber which is secured in fixed relation to a shaft. The chamber receives the soap pieces and is formed by sides and removable top and bottom plates. The edges of the top plate are closely circumscribed during operation by the sides of the chamber. The top plate is movable within the chamber in a direction parallel to the walls thereof. The bottom plate is removably secured across the bottom of the chamber. The press further comprises means to apply pressure to the top plate of the chamber, which consists of an eccentric cam rotatable about an axis. The cam during operation bears against a portion of the top plate and as it rotates about its axis forces the top plate into the press chamber to a predetermined distance, to apply appropriate pressure to soap pieces within the chamber.
