Application June 4, 1943, Serial No. 489,613 1 Claim. (Cl. 74—604) 1 The present invention relates to an internal combustion engine or other mechanism including a piston and crankshaft, and especially to a novel means and‘method of balancing an engine of the 2 embodiment disclosed in the ‘drawing; the single cylinder internal combustion engine I is shown as provided with a crank case 2 mounted upon a base 3 and having a cylinder 4 provided with cir single cylinder type for most effectively counter cumferential cooling or radiating. ?ns 5 exposed acting or eliminating the vibrations incident to to the atmosphere. A piston 6 is adapted to re the operation of such an engine. , ciprocate within the, cylinder 4 and it in turn Among the objects of the present invention is reciprocates a connecting rod 1 having its upper to provide an internal combustion ‘engine‘of the end connected to the piston by means of a wrist single cylinder type in which the tortional and 10 pin 8, and its lower sleeved end 8 split and encom other vibrations incident to the reciprocation and passing a crank pin l0 carrying at its opposite operation of the piston and connecting parts is ends the spaced eccentric weights H and l 2.

The invention further comprehends providing vertically upward as in Figure 4 or in a position concentric weights such as ?y wheels 24, 24 on the sections of the crank shaft and a weight or Having thus disclosed my invention, I claim: In an internal combustion engine comprising ?y wheel 25 on a section of auxiliary shaft keyed to and rotating in opposite directions with their a single upright cylinder, a piston reciprocable in said cylinder, and a horizontally disposed 180° therefrom, they balance the piston 6. This effectively prevents or counteracts the usual vi brations incident to the operation of a single cylinder engine. respective shafts.
