Description: |
| "My invention consists of a chamber with certain branches in combination with an internal nozzle, the whole being constructed and arranged substantially as described hereafter, so as to form an injector of the most simple and inexpensive character, compared with the elaborate and costly instruments known as 'Giffard's inject.'" See patent 27,979 for Giffard's injector. The year after this (Millholland's) patent was issued, Millholland built what was at the time the world's largest locomotive engine, the Pennsylvania, which reportedly used his injector. According to Strickland L. Kneass in his 1898 book, "Practice and Theory of the Injector", "Millholland, of Reading, Pa., patented in 1862 an injector formed of non-adjustable tubes, depending upon the use of external valves for regulation; but this met with no success, and does not appear to have ever gained publicity." |
