Abstract: A variable-ratio transmission device. A first translational member is pivotally intercoupled to a first rotational member by at least one connecting arm. The connecting arm has a first portion pivotally connected to the first translational member at a first pivot point, and a second portion pivotally and adjustably connected to the first rotational member at a first radial attachment point removed from the center of rotation of the first rotational member. The first radial attachment point and the center of rotation thereby define a first attachment radius. The location of the first radial attachment point with respect to the first rotational member is variable to thereby increase and decrease the first attachment radius, which in turn modifies a ratio of movement between the first rotational member and the first translational member.

Abstract: A variable stroke crankshaft assembly includes a drive shaft surrounded by a sleeve. A crankshaft is disposed inside the drive shaft with the longitudinal axis of the crankshaft offset from the longitudinal axis of the drive shaft. A gear projecting outwardly from the crankshaft through a window in a drive shaft engages angled gear teeth on the inner surface of the sleeve allowing sliding movement of the sleeve relative to the drive shaft to rotate the crankshaft. A crankpin is attached to the crankshaft but offset from the rotational axis of the crankshaft. Rotational movement of the crankshaft with respect to the drive shaft thus pivots the crankpin with respect to the rotational axis of the drive shaft creating a crank stroke that may be varied by sliding the sleeve back and forth.

Abstract: A multi-piece crankshaft having a main shaft with two ends adapted to rotate about its axis. A crankpin also has two ends and an axis parallel to but radially spaced from the axis of the main shaft. At least one counterweight extends between one end of the shaft and one end of the crankpin and this counterweight is formed by casting a liquid metal around the ends of the main shaft and crankpin in a molding chamber.

Abstract: A crankshaft being integrated with stemmed, inertia-forced lobes that increase engine and motor efficiency, in which a respective lobe extends and branches out to a single traversal side of crankshaft integration, and thus being right-angular to its integration. Essentially, the lobe is a structurally-curved limb having respective curvature about the traversal axis of crankshaft rotation. Hence, the ensuing inertia from the lobes actually rotate. in the same direction and in parallel with the crankshaft, and thus retaining at least 99% of lobe force, to significantly increase engine and motor output power. By contrast, conventional lobes retain only 50% of inertial force. Furthermore, if the lobes' outer extended, weighted portions are “loaded” with very heavy material, such as lead, then the power output becomes proportionally greater. A description with illustrations of a simple experiment demonstrates the “Coriolis effect” to affirm the extraordinary operation of this crankshaft.

Abstract: A crankshaft assembly for an internal combustion engine having a one-piece elongated shaft adapted to rotate about a longitudinal axis. The shaft includes a radially offset portion between the ends of the shaft, and this radially offset portion is spaced axially inwardly from each end of the shaft. An elongated connecting rod having a one-piece annular bearing support at one end is secured to the shaft so that the annular bearing support is positioned around the shaft offset portion. A first counterweight is secured to the shaft adjacent one end of the shaft offset portion while a second counterweight is secured to the shaft adjacent the other end of the shaft offset portion. In an alternate embodiment, the crankshaft, crankpin and one counterweight are formed as a casting. A one-piece connecting rod is then slid onto the crankpin and a second counterweight is molded to the crankshaft on the side of the crankpin opposite from the cast counterweight.

Abstract: A multi-piece crankshaft having a shaft with two ends, an axis and adapted to rotate about its axis. A crankpin also has two ends and an axis parallel to but spaced radially outwardly from the shaft axis. The crankpin optionally has at least one indentation. A plate has two spaced openings such that one end of the shaft is positioned in one of the plate openings while the other end of the shaft is positioned in the other plate opening. At least one counterweight extends between said one end of the shaft and said one end of the crankpin, and this counterweight is formed by casting a liquid metal around the ends of the shaft and the crankpin as well as around the plate. The liquid metal fills the at least one indentation and, upon hardening, locks the counterweight to the crankpin and shaft and encases the plate.
