CARTER'S OSCILLATING ENGINE
The annexed engraving represents one of Carter's ten-horse power oscillating steam engines. The advantages claimed for this invention are as follows:— It has a plain slide valve, working on a three-ported seat, enclosed in a steam chest; consequently there are no working joints, so common in some kinds of oscillating engines, to wear loose and leak, and no set screws required to keep the cylinder in position. The valve movement is simple, compact and durable.
In the engraving, A is the steam chest, and B the valve stem, which runs through the right-angled arm, C, and is made adjustable thereon by means of two nuts on the top and bottom of the arm. In the link, D, there is a composition box, which is connected to the arm, C, with a pin. When the cylinder oscillates it causes this arm, C, to travel in the stationary link, D, giving a reciprocating movement to the valve. This movement, the inventor says, is remarkably quick, and the engine starts from very near the center easily, without lead. The steam is let in and out through the trunnions, as usual, which are both of the same size. These engines are in successful operation, and prove entirely satisfactory.
It was patented through the Scientific American Patent Agency on July 25, 1865, by Henry T. Carter, of Portland, Maine, to whom all orders and communications must be addressed.
