Mid-Century Modern American Duplex Commercial Coffee Grinder & Store Display



This commercial coffee grinder was made by the American Duplex Company of New York city in circa 1965 in the period Mid-Century Modern style. This is American Duplex's Grindmaster 500 model and is done in a bright yellow and contrasting black body panels and vibrant red labeling. This commercial coffee grinder doubles as a store display and was intended to advertise a bag of coffee beans in the lighted window on the front and for customers to grind the beans to a variety of grinds before taking them to the checkout counter with their groceries. This grinder has a flip up top which exposes the tin chute that the customer pours the beans into and then places the bag under the spout at the rear of the machine, and pushing the bag upwards activates the grinding mechanism. The bag sits on a sliding adjustable metal shelf depending on the weight of the product. The rear of the machine is decorated with various colorful labels and directions done in alternating red and white lettering and borders. The machine is rated for 115 volts, with 7 amps and 60 cycles.
