New Automatic Cut-Off Engine
We present on this page an engraving of a new style of automatic cut-off engine adapted to the uses of those who desire moderate powers, economy and uniformity of speed. The first noticeable feature about this engine is that it is self-contained. The form of the bed is such as to give the utmost strength and stiffness. The crank-shaft is of bent steel, thus giving a large bearing surface to the connecting-rod, and applying the power just where it is needed, that is, between the load. It has two balance wheels, perfectly balanced.
The automatic cut-off regulator is attached to the crank-shaft, and takes hold of the valve-rod directly, thus avoiding all complicated rocker-arms. The valve is a Hat balanced valve, which, it is claimed will not become leaky from use.
The cut-off acts instantaneously and controls the engine at the desired speed whatever may be the load, or pressure of steam, and, it is claimed, the variation from an extreme light load to the capacity of the engine will not exceed two per cent.
So far as workmanship and choice of materials are concerned, there seems to be nothing omitted. It is claimed that these engines are as simple as the ordinary throttling valve engine, and require as little care, at the same time the cost of fuel being less.
The manufacturers are Armington & Sims, Lawrence, Mass., and the selling agents Hill, Clarke & Co., Boston, Mass. |
