Patterson's patent "consists in combining with the ordinary rakes used to stir the mash, two or more hollow perforated steam arms which revolve in the tub and, receiving steam from a suitable boiler, diffuse it through the mash in so uniform a manner as to keep the mash at an even temperature during the whole operation, thus greatly facilitating the process of distilling, and increasing the yield of spirits from the grain." (Patent number 29,713)
