The Springfield Gas Engine
The engines of the Springfield Gas Engine Company are of the four-cycle compression type, adapted to the use of illuminating gas, natural gas, producer gas, gasoline gas, and gasoline fluid by injection.
The inlet and exhaust valves are of the poppet type, actuated by cams on a cross shaft over the cylinder head, the cross shaft being driven by a longitudinal shaft and two pairs of bevel gears.
The cams Nos. 18 and 19 on the cross shaft (Fig. 93) operate the inlet and exhaust valves by depression against internal pressure, the valves being also held to their seats by springs.
The governor is of the horizontal, centrifugal type, running free on the end of the cross shaft and driven by a small belt from the main shaft. Fig. 93 shows an end view of the engine as fitted for gas. An air valve No. 8 and the gas valve No. 35 are on a vertical spindle, which is operated by a cam, rotating with the cross shaft and controlled in its longitudinal motion by the governor, making an off-and-on charge. The portion of air charge is fixed by the set of the air valve, and the proportion of the gas charge is regulated by adjustment of the gas valve, which is set by raising or lowering the gas-inlet pipe No. 6 in the mixer No. 10 by means of the set-screws No. 7.
For the use of gasoline a small supply pump, driven from a cam on the longitudinal shaft, supplies the fluid to the injection plunger with an overflow to return the surplus to the gasoline tank. |
