Whitman’s Confectionery Machine
Whitman’s machine for manufacturing confectionery used a steam-filled box surrounding the body to heat the pre-molded batch which was to be poured into multiple vessels located on the top. The underside had funnel-shaped apertures where different types of molds could be attached to cast the confectionery. A lever controlled a sliding gate underneath to control several streams of material simultaneously.
