9、ional food products. This device also includes an endweigh or spring to permit slicing of product to within the lastone-quarter inch.3.1.3 gage platedevice that determines the thickness of anindividual slice of food product.3.1.4 gage plate adjustermanually operated device (usu-ally a dial or a leve
