CUT-OFF STEAM ENGINE.
The new cut-off steam engine (says a New York journal) invented by Knapp Brothers, and now manufactured by them, promises to be a most valuable improvement in the working of engines. Two of the engines are now at work in their shop on Patch street, and a-o well worth a visit. By the invention of tho Knapp Brothers double the power can be got from an engine. That is, one of their fourhorse power engines can be run to its full eapaoity by a two-horse power boiler. Their engine takes steam at eighty pounds pressure and does not exhaust until expanded down to twenty pounds. It thus has an average pressure of fifty pounds per inch on the piston the entire length of cylinder. So confident are the inventors that their engine will do double the work of another that they will forfeit it in case of its failure to do so.
