This invention relates to improvements in lawn-mowing machines, and consists, First, in the arrangement of the driving gear. For this purpose the inventor fixes on, or casts in a place with, the side frame of machines an internal toothed circle, which works a small pinion mounted on the crank pin of a crank mounted on and revolving with the main axle of the machine, which crank pinion is thrown out or into gear by a sliding clutch in the usual way. This crank and pinion again takes into a second pinion mounted loose on the main axle outside the framing. Of a piece with or fixed to this pinion is a larger spur wheel, which takes into an intermediate stud wheel, transmitting the motion to a pinion fixed on the axis of the revolving cutters. By this arrangement of the gearing a high speed is obtained in the cutter, with a simple and compact arrangement of the gearing. The Second part of the invention consists in the use of India-rubber, gutta-percha, leather, or any other suitable substance or composition, as a material for the formation of the toothed gearing or surface communicating the motion, which it transmits without noise.-Not proceeded with.
