Abstract: The improved motorized gearbox mechanism of the present invention includes a plurality of cam-actuated gear block assemblies, which transfer power from an integral rotor and stator assembly contained in a cam/rotor assembly, to a secondary or output gear element. Each gear block assembly includes a gear block having a surface that periodically interfaces with a secondary or output gear element. When energized, the stator assembly interacts with the rotor assembly inducing the cam/rotor assembly to rotate about its central axis, thereby driving the output gear element via the plurality of cam-actuated gear block assemblies. The motorized gearbox mechanism may be powered electrically, hydraulically, pneumatically or by steam, or any conventional power source that can be adapted to use an integral stator/rotor assembly configured in the cam assembly body to generate rotative power in the cam/rotor assembly.

Abstract: A continuously variable transmission (CVT) can include a rotary cam member defining an internal cam surface operably engaged with a cam follower assembly for generating a displacement waveform with a constant velocity portion. A ratio control assembly can restrain the cam follower assembly for reciprocal linear movement and can scale the reciprocal linear movement between at least 0% and 100%, inclusive, in response to an angular orientation of the ratio control assembly. An output assembly can convert the scaled reciprocal linear movement into rotary movement of an output shaft. A CVT method can include generating a periodic displacement waveform with a constant velocity portion, scaling the periodic displacement waveform between at least 0% and 100%, inclusive, with a ratio plate, where the scaling is in response to an angular orientation of the ratio plate, and converting the reciprocal linear movement into rotary output with a combiner.

Abstract: The invention relates to a gear transmission with a steplessly adjustable translation ratio for converting of rotary speeds and of torques of shafts. The uniform rotary motion of a drive shaft is transferred to a driven shaft with the aid of time staggered operating gear transmission units. The rotary motion is transformed by a cam transmission initially into a uniform translational motion and in the following this uniform translational motion is transformed into another, also uniform translational motion, with a speed depending on the translation ratio setting with a translation device. Finally this translational motion is transferred again into a uniform rotary motion by a further planar cam transmission and transferred to the driven shaft.

The various elements are also assembled in such a way as to form sealed variable volume chambers.

Abstract: A system for use in a press machine includes a drive assembly in the form of a pinion gear that selectively engages the flywheel to enable operative driving rotation of the pinion gear by the flywheel. A load system in the form of a hydraulic pump is arranged in operative driving relationship with the pinion gear.

Abstract: A worm-like drive mechanism has a plurality of axially-spaced eccentrics rotated by an input shaft located at right angles to an output shaft. A wheel mounted on the output shaft has a circumferential surface with periodic undulations. Oscillators in the form of rollers mounted on pins and captured in respective slots of a fixed carrier are reciprocated through contact with the external surfaces of the eccentrics to cause the undulated surfaces of the wheel to move, thereby driving the output shaft. Contact between the rollers and the eccentrics is achieved through the intermediary of bars which are reciprocated with the rollers.

Abstract: A mechanical transmission converts rotational motion of an input drive shaft to an alternating radially directed motion of a selected amplitude. The alternating motion imparts rotational movement to an output driven shaft through imposition of one-way clutches. The alternating radially directed motion is varied by means of a rotatable self-balancing cam assembly. The self-balancing cam assembly includes a working, radially offsettable cam component and a compensating counterbalance. The cam and counterbalance are interconnected by a plurality of eccentric orbital coupling elements which rotate with the input drive shaft and are selectively rotatable thereabout. These impart simultaneous radial movement to the cam and counterbalance as desired to maintain the transmission in a dynamically balanced condition over its full range of operation.

The slide has a cantilever spring arm which carries a pawl tooth at its end to engage successive teeth provided on the periphery of a switch operating cam drum or disc. A cantilever leaf spring is provided which bears against the slide to urge the pawl tooth into engagement with the cam disc or drum in the event the cantilever spring arm becomes permanently displaced toward the slide.

Abstract: A drive mechanism for imparting intermittent movement to an output member. The drive mechanism includes a rotatable input member which operates through a crank to move a beam with oscillatory or reciprocating movement. The beam is interconnected with a one-way overrunning clutch associated with the output member so that oscillatory movement of the beam is transmitted to the clutch. The clutch is designed such that rotation of the clutch in a first direction will cause the clutch to engage the output member to rotate the output member, while the clutch is freely rotatable with respect to the output member in a second direction. A resilient member, such as a compression spring, interconnects one end of the beam and the clutch and if the output member encounters an excessive load, oscillation of the beam in the first direction will compress the spring to provide overload protection for the drive. A second overrunning clutch can also be associated with the output member and is fixed against rotation.

Abstract: The present invention relates to a programmer control device comprising a rotary cam block capable of being driven in rotation step by step by an advancing cam actuating an oscillating pawl carrier.The control device possesses means of blocking and releasing the action of the pawl, comprising a blocking lever 50' interacting with means capable of rocking the said blocking lever between two angular positions during each to-and-fro movement of the advancing pawl. In the first position, a part 51' of the blocking lever is located in the path of a slope 55 of the pawl 21, so as to prevent the action of the latter. In the second position, the part 51' is not located in the path of the pawl 21, so as to permit the action of the latter.

Abstract: A sequential ratchet drive for an appliance timing cam is disclosed. The drive includes a pawl adapted to drive ratchet teeth located on the periphery of a main program cam in a step-by-step manner. The pawl is driven and guided by cams against and with the bias of springs in an initial tangential drive path in driving engagement with a ratchet tooth. The cams guide the pawl out of engagement with the driven tooth in a curvilinear retraction path with the bias of a first spring and against the bias of a second spring to a raised location and then the pawl is returned to its initial driving position by the bias of both springs. A portion of the path of travel of the pawl from its raised location to its initial position may be defined by a portion of a ratchet tooth so that the retraction path of the pawl may adapt itself to a variety of varying tooth spacings.

Abstract: A programmer comprising a cam unit which can be rotated manually in a first direction by a control shaft 23 able to occupy, under the action of a pawl device comprising a spring, any one of several equidistant stable angular stop positions spaced apart by the angular value of one step, before passing on each occasion through a limiting unstable intermediate angular position, after which this shaft is brought in a resilient manner by the pawl device towards the following stable angular stop position. A motor and drive transmission system are able, when controlled, to rotate the cam unit step by step in said first direction. The cam unit is connected to rotate with the control shaft, with an angular clearance less than the angle through which the shaft travels, between any one of its stable angular stop positions and the limiting unstable intermediate angular position which follows.
