Antiseptic machine, England, 1879
Anthony Bell, a surgeon based in Newcastle, patented the design for his device in 1879. The machine was used to make the surrounding air antiseptic. The hammer tapped the base of a small container of medicated powder, rather like an upside down salt shaker. The powder was sprinkled into the path of a fan in the tinned cylinder at the back of the machine. Air from the fan was propelled through a piece of gauze sprayed with carbolic acid. The medicated powder and the carbolic acid combined to rid the air of germs.
