D. Stevens, of Leon, N, . Y., has taken measures to secure a patent for an improvement in the mode of gearing reciprocating motion—no belts, pullies, or wheels of any kind are used in the arrangement invented by Mr. S., he simply uses the double toggle joint motion, and carries it past its toggle or moving centre, so as to obtain two strokes ot a cross beam, or an entire revolution of a crank for each single stroke of a motor attached to the toggle joint; by this method a most effectual and simple gearing may be constructed.
