McClave Ad in Manufacturers Record | MCCLAVE AD IN MANUFACTURERS RECORD - William McClave was issued 80 patents by the US and foreign patent offices. His first patent for the oil wick lamp was clearly his least successful. The last 79 patents pertained to grates, stokers and blowers for furnaces and boilers. This ad in the August 18, 1921 issue of the Manufacturers Record, some 56 years after he received his first patent, shows his success in the combustion systems business. | Original Image |
