lchc cylinders and 11 of each pair of cylinders reciprocate pistons 13, 14 connected by piston rods l5, 16 with yokes 17, 18, alike in construction, so that it suffices to describe but one in detail. Each yoke 17, 18 is provided with two parallel guideways 20, 21, in which are mounted to slide hearings 22, 23 engaged by the crank pins .24, 25 of cranks 26, 27 forming part of crank shafts 28 29 journaled in suitable bearings arranged on the main frame or base 12.
The crank shaft 28 isthe power-driven eiaft and provided at one end with a fly Wheel 7 and the crank shaft is a counterbalance shaft and is provided with a fly wheel 31 at the side of the engine opposite iihe one on which the lay Wheel is located, as will he readily understood by reference to Fig. 5"). The guirleways 20 and 21 of each yoke 17 and 18 extend transversely, that is, at a right angle to the axes of the shafts 261, 29. and the coniplcinentary cranks 26, 27 arc. so arranged one relatively to the other that the hearings 2;. 23 slide in opposite directions in their guideways 2,0 and 21.
'iho shal'ts and. 2 are connected with it islmdcrstood chat the cranks Q6 and likewise the cranks 27 are arranged at angles one relatively to the other on the corresponding crank shaft 28 or 529, so that the power of the explosive agent is transmitted in the shaft 28 in the proper sequence according to the number of cylinders of the engine. it is expressly understood that each yokc has two parallel guideways 20 and 21 in which reciprocate the bearings 22, 23 in opposite directions during the running of the engine. The crank movement shown and described is preferably inclosed in a double casing--l0 as indicated in Figs. 1 and 5.
The crank movement shown in Fig. 5 is the same asahove described but is shown applied to the piston rod of a piston 51 moonied to reciprocate in the cylinder 52 "of an internal combustion engine of the four-cycle hype.
formed of topand bottom plates 69, 61 enneonates gaging at their ends screw rods 62, 64: provided with nuts (34, 65, of which the nuts 6% engage the top of the plate while the nuts engage the bottom of the plate 61, the two plates (30 and 61 being held spaced apart by spacing sleeves 60, 67 through which extend the corresponding portions of niost plate 60 of the. guideway 20, and the two guideways 20 and 21 are held adjustable on the two rods 62, 63 to space the same the desired distance apart and to space the in dividual plates 60, 61 and "Z0, 71 apart to insure proper sliding movement of the bearings 22 and 23; When the engine is running the power developed in the cylinders 10 and 11 is transmitted by the pistons 13, let to the yokes 17, 18 which by their bearings 22, 23 engaging the pins 24:, 25 of the cranks 26, 27 cause a rotary motion of the shafts 28, 29, and as the latter are geared together and the bearings 22, 23 travel in opposite directions it is evident that the shafts 28 I) and 29 rotate in opposite directions. As the shafts carry fly wheels at their opposite ends a complete counterbalancing of the engine is had to insure an easy running of the engine.
Having thus described my invention, *1 claim as new and desire to secure by Letters Patent: I
