(01. 143-43) This invention relates to portable saws, and more particularly to a portable saw for cutting into desired lengths logs to be used for pulp wood or ties or the like. The object of the present invention is to pro vide an improved portable saw of the type indi cated, peculiarly adapted to being maneuvered on the rough ground and in the underbrush com monly encountered where the logging operations 2 members I 2-I2 is an internal combustion en gine I4, the pulley I5 of which is connected as by the double belt It‘ ‘with the pulley ‘I’ mounted on the saw shaft 6. A fuel tank I 8 for the engine Hi can be conveniently mounted upon the upper side of the handles I adjacent the engine. Legs I'I-I ‘I can ,be also provided on the handles I so that when not in use the saw will be supported by tl|1e ground contacting wheel I0 and the two are in progress, so that it can be readily posi 10 legs ‘I. tioned with respect to the fallen logs to cut same In operation it will be apparent that by grasp at desired points without the necessity of moving ing the rear end of handles I —I the entire device the logs either to level the same or change their can be manipulated like a wheelbarrow on the one position on the ground. _ ground contacting wheel I0 and approached at Further objects will appear in the course of 15 any angle to a fallen log regardless of the rough the following detailed description. ness of the ground.
