Improved Baker's patent mangle; having three rollers, two of which revolve with the linen rolled upon them under the heavily-loaded box, while a third is being prepared with other linen to replace the first and continue the process.
Improved patent box churn. The top or cover has perforations for admitting atmospheric air, and the beater is of the form found by experience to be best calculated for agitating the cream, and forcing the air through it, so as to improve the quality and increase the quantity of butter.
