The Hartig Gas Engine
The engines of the Hartig Standard Gas Engine Company are all made in the vertical style for gas or gasoline vapor, from a carburetor that gives a saturated air-vapor mixture, which is not explosive until a further admixture of air in the mixing-chamber of the engine completes its explosive quality. The engines are of the four-cycle compression type; ignition by hot porcelain tube or electric spark, and time igniter for the hot tube. The valves are of the poppet type. The exhaust valve is operated from a reducing-spur gear by crank p1n, rod, and lever. The governor is of the centrifugal lever type, connected to a cam sleeve that has a circular motion by the movement of the balls, and a longitudinal motion by a spiral slot in the sleeve moving over a fixed pin in the main shaft. By this means the longitudinal movement of the sleeve rides the push-rod roller of the gas valve on to or off the cam, in such a way as to graduate the gas charges to meet the speed emergency.
The adjustment of the governor is made by spiral springs holding the balls in the position for normal speed.
The inlet-valve stem carries a double disc. The lower one is proportionally small for the gas passage, while the air is drawn in between the discs, the upper and larger valve discharging the mixture into the explosion chamber.
Fig. 126 illustrates the power engine, which is made in several sizes, from ½ to 8 B. H. P.
Fig. 127 represents the pumping attachment operated from spur gear, all fixed complete on one base.
These engines as observed run on a consumption of from 18 cubic feet of gas in the larger sizes to 20 cubic feet in the smallest size per horse-power per hour. The pumping engines are of a capacity to force water to the highest city buildings. |
