The Backus Gas Engine
The engines of the Backus Water Motor Company are built in the horizontal and vertical styles, as illustrated in Figs. 123 and 124. The horizontal engines are built in fifteen sizes, from 5 to 60 B. H. P. They are of the four-cycle compression type, with the principal exhaust ports in the side of the cylinder opened by the piston at the end of the impulse stroke. They have also a supplementary exhaust valve in the cylinder head, with its exhaust passage connecting with the main exhaust. The exhaust push-rod is operated by an eccentric on the reducing-gear shaft, and carries a pendulum governor pivoted in the square box seen in the illustrations of the horizontal engines (Figs. 122 and 123). The push-blade of the governor is pivoted in the same box as the pendulum, with one end loosely locked in an Y-extension of the pendulum. The adjustment can be made while the engine is running, by a small screw seen in the front side of the small box, which compresses a spiral spring against a lug extending upward from the pendulum socket. The concave piston and cylinder head are used in the Backus engines for the greatest volume in the combustion chamber with the least wall surface. |
