Murdock Injector, Patent Model

Description:

This injector was submitted to the U.S. Patent Office with the application for the patent issued to Horace B. Murdock, of Detroit, Michigan, November 11, 1890, no. 440183; assigned to the American Injector Co.

This is a double injector having two force tubes arranged in parallel order and operated with a single actuating shaft. The overflow valves as well as the steam valves of the two sets of tubes are operated by the same shaft so that the steam valve of the first set opens in advance of the steam valve of the second set and the overflow valve of the first set closes in advance of the second set. The stems of all conical plug valves are extended outside of the injector shell and are provided with slotted ends by which they may be turned with a suitable tool to grind upon the valve seats.
