Penberthy Injector was incorporated in 1886 to manufacture an improved steam injector, a device which feeds water into steam boilers, invented by Wm Penberthy. After a boiler explosion, which killed 26 workers and destroyed their factory on the northwest corner of Abbott Street and 7th Street in 1901, they bought 5½ acres on Greenwood, Holden, and the Grand Trunk RR, and built a new factory. They made injectors of different types for boilers, ejectors, valves, lubricating devices, gasoline and oil guages, carburetors, re-atomizers, flowmeters, etc. During World War I, the Penberthy Co manufactured carburetors for tanks and ordinance materials of various kinds, and for this work received a citation from the U.S. Government. A second plant was opened on Goldsmith Avenue for the manufacture of steel parts.
