The Nash Gas Engine
The Nash engines are built by the National Meter Company. They are of the vertical style, in nine sizes from 1/3 to 10 H. P. with single cylinders; and in ten sizes from 10 to 200 H. P. with double and quadruple cylinders. The smaller engines are of the two-cycle compression type, taking an impulse at every revolution in each cylinder, thus making the action of the double-cylinder engines equivalent to the action of a single-cylinder steam engine or an impulse at each half-revolution of a single crank.
The double-cylinder engine (Fig. 133), the single cylinder with double fly-wheel (Fig. 132), and the small single cylinder with one fly-wheel (Fig. 134) represent the general appearance of the engines of this company. They are all adapted for the use of illuminating gas, gasoline, natural or producer gas. Ignition is by hot tube or the electric spark, as desired.
The larger engines have poppet valves, and are of the four-cycle compression type, and are now made in one-, two-, and four-cylinder vertical style, with reducing-gear and cam shaft, which operates the inlet and exhaust valve by direct-acting push-rods with back springs. The inlet-valve push-rods have bracket arms with pivoted push-blades that regulate the gas charge by the governor through a rock shaft and levers, which trip the push-blade contact for each gas-inlet valve.
This class of two- and four-cylinder engines is built in many sizes, ranging up to 200 B.H.P., with multi-polar generators on the same base for electric lighting. Also combination pumping engines on a single base for deep wells; also combination engines and air compressors adapted to any required air pressure. |
