THE NATHAN MANUFACTURING COMPANY’S MONITOR INJECTOR.
Fig. 3.
One of the most successful and enduring injectors in use is the Monitor, the distinguishing feature of which is, that the injector is constructed with fixed nozzles, that insure great durability, combined with certainty of action. The Monitor injector is shown in section in [Fig. 3]. To start the injector, the middle cock is opened, which is the lifting-jet. When water appears at the overflow, the steam-valve is opened, and the lifting-jet closed. The work of the injector is regulated by the lazy-cock, which is the bottom handle. A movable valve, operated by an eccentric on the stem, is now employed as a lazy-cock; a common cock having been found troublesome during frosty weather. The combining-tube is attached to the line-check, and can be taken out with the check, which provides an easy means of effecting examination or repairs.
