A wobble drive mechanism for a translationally moving structural part includes a wobble rod which is moved by way of a crank drive mechanism. The wobble rod includes a spherical section at one end thereof that is seated in a bearing bush of a crank. At its opposite end, the wobble rod includes a second spherical section that is seated in a stationary structural part. A third spherical section is positioned between the two ends of the wobble rod and is seated in the translationally moving structu...

A rotary-to-linear motion converter comprising a frame having a roll axis, and a pitch axis passing through a common point. The axes are mutually orthogonal. The common point is positioned between an input end and an output end. An input shaft rotates on the roll axis and has an offset drive cam on its interior end. The offset drive cam has a central point positioned at the frame common point. A rocker housing has a pitch axis and a yaw axis. The pitch axis and yaw axis are mutually orthogonal a...

The wobble plate engine mechanism includes a cylinder block and mainshaft; a drive hub obliquely mounted for rotation with the mainshaft; a wobble plate rotatable around the hub; cylinders spaced around the mainshaft; and a piston moveable in each cylinder and couple to arms of the wobble plate. Piston and arm couplings comprises a cross-head reciprocable in a piston bore and a gudgeon pin moveable end-wise in a cross-head bore; the cross-head bore and ends of the pin defining cavities so lubric...

The invention is a volumetric piston chamber machine wherein the crankpin is relieved of the inertia force and wherein a seat is constructed in a single piece adapted to act as a female part with the crank being a male part. As a result, the force distribution throughout this volumetric piston chamber engine is more uniformly distributed and offers the advantage of a smaller engine in the overall axial direction eliminating the harmful transverse stresses.

A barrel mechanism comprises, with a casing, a rotatable shaft mounted in two bearings supported respectively by two ends of the casing perpendicular to the axis of the shaft, and to which is fixed a plate oblique with respect to the axis, a barrel bearing on the oblique plate, centred about an axis, intersecting the axis of the shaft, on an inclined cylindrical bearing on the shaft and perpendicular to the plate, and a means locking the barrel against rotation, wherein the two ends of the casin...

The invention relates to a driving mechanism for a reciprocating engine, comprising a casing, a drive shaft which is rotatably mounted in said casing and a transmission means for power transmission from at least one reciprocating piston to said drive shaft.

A wobble device is provided including a circular platform, a structure for pivoting the platform to achieve a wobbling movement, a shaft transverse to and positioned in a center of the platform, a moveable carriage rotatably attached through an arm to the shaft, a roller structure for moving the carriage on an upper surface of the platform, and a support frame below the platform. A forcing structure attached to a plurality of extension members downwardly directs the platform tilting an end of th...

Translation/rotation conversion apparatus includes a rotatable follower shaft having an oval follower slant mounted thereon at an oblique angle with respect thereto. A rotatable drive shaft is disposed parallel to the follower shaft and has an oval drive slant mounted on it at the same oblique angle with respect to it that the follower slant makes with respect to the follower shaft. Planar faces of the two slants are engaged together in flat overlapping relationship. At least one shaft, preferab...

A variable stroke piston engine in which power developed by piston reciprocation is transmitted to a cylindrical nutating member journaled on its exterior to a rotatable support connected to a second shaft concentric with the first shaft, the nutating member having an internal surface in frictional engagement with a pair of oppositely convergent cone-like members keyed for rotation with the first shaft. The nutating member is disposed on an axis inclined with respect to the axis of the first sha...

An expansible chamber energy conversion machine, such as an internal combustion engine, in which one or more reciprocating pistons drivably revolve a nutating member about an output torque delivery shaft in a manner to enable variation in piston stroke distance. The nutating member forms part of a variable speed ratio transmission and is adjustably supported on an axis inclined to the output shaft by an eccentric sleeve rotatable with respect to a support rotatable on the shaft axis. Piston reci...
