Messrs. Tatum & Bowen, of this City, the agents here, have supplied the above fine engraving of an automatic engine, made at the Erie City Iron Works, that may in sense be called a condensation of modern features in engines of its class. Familiarity with steam engines at this day renders it almost unnecessary to write descriptions of them, when they are properly engraved and the view taken from a good position. This remark applies in the present case and our readers can follow out almost every detail.
The governor, it may be observed, does not have an eccentric with a radial movement, but a pin and cross slide which keeps the lead almost uniform on both strokes. The overhang eccentric which originated, so far as we know, with so good an authority as Mr. Chas. T. Porter, has some obvious advantages, especially when a piston or other balanced valve relieves the gearing of much strain. The slight elasticity produced by the rocking frame is not an undesirable feature at high speeds.
It has been a very interesting study for some years past to follow the evolution of high-speed engines. It has been a work of observation and experiment, because the enormous strains, when computed, furnished little clue to the mechanical means of resisting them.
The engines shown above are made from 8 to 15 inches bore, are steam jacketed and good examples of modern high speed design. |
