Charles Stahlberg's patent of Sept. 22, 1885 describes the basic process used to make United Clock Co., Western Clock Mfg. Co., Western Clock Co. and Westclox clocks. To make a wheel and pinion assembly, steel pinion and pivot wires and the brass wheel were held together in a jig while a molten lead alloy was poured in. Then the lead alloy solidified, holding the steel and brass parts firmly in place.
Andrew Neureuther's patent of October 28, 1902 is for a wheel and pinion assembly used by Western Clock Company and Westclox. It is an improvement on Stahlberg's 1885 patent. To make a wheel and pinion assembly, steel pinion and pivot wires and the brass wheel were held together in a jig while a molten lead alloy was poured in. Then the lead alloy solidified, holding the steel and brass parts firmly in place.
