This form of English engine was taken up by the Dickson Mfg. Co. of Scranton, Penn., and put on the American market in 1885. It is of the type using a separate compression cylinder, and firing every revolution. This cylinder is located axially or on a line with the power cylinder, the two pistons being rigidly connected and serves as a pump to force in the charge for the succeeding impulse. It is said, however, that this charge driving out ahead of it the products of combustion of the preceding explosion lost part of its strength at the same time, and that disappointment was experienced over a higher rate of gas consumption than the Otto or similar makes, or than was expected. This was a chief reason for the later dropping of it by the American makers. Otherwise, a sample engine on exhibition in Philadelphia seemed to the writer peculiarly attractive from its neat appearance and smooth and quiet operation. A novel governor was a feature, regulating by skipping charges, like the Otto; its work has been criticized. No cams or gears were used. A slide valve and tube ignition were used. It was catalogued in both vertical and horizontal form, in sizes from 1 to I0 H. P. In Stevens Institute tests the 2 H. P. Nom. developed, at I80 revolutions, 3 Brake H. P., with a consumption of 31.26 cubic feet, which on this small size was certainly satisfactory work. In England its general record has been materially better. A well-known gas firm, handling it in numerous other and better forms, have there made it one of the prominent engines. |
