| Number | Title | Issue Date |
| 6105447 | Eccentric crank with continuously adjustable throw The invention provides an eccentric wherein the amplitude of reciprocation, or throw, is continuously variable, during operation, from zero to a maximum. This represents an improvement over adjustable eccentric devices in the prior art insofar as the conv... | 08/22/2000 |
| 5090081 | Windshield wiper with variable arcuate pattern A windshield wiper includes a first pin connected to a drive mechanism, a primary lever supported by the first pin, a second pin mounted to the primary pin, a wiper arm fixedly mounted to the second pin, the primary lever being rotated about the second pi... | 02/25/1992 |
| 4914981 | Intermediate transmission for converting a rotation into the reciprocation of a roller in inking and/or damping units of offset printing presses An intermediate transmission with a variable input-to-output phase relationship for converting rotary motion to reciprocal motion includes a drive shaft having a main portion and an eccentric crank pin, an externally toothed ring with a plurality of circu... | 04/10/1990 |
| 4682532 | Variable-stroke constant-compression-ratio reversible radial pump A variable-stroke, constant-compression, reversible radial pump, the stroke of which may be infinitely adjusted by means of a variable-throw eccentric from a normal-cycle maximum through zero to a reverse-cycle maximum, and the compression of which is mai... | 07/28/1987 |
| 4558266 | Workpiece transfer apparatus A workpiece transfer bar is reciprocated by a rack driven by a pinion which is driven by a servomotor through an eccentric arm. A computer is used to set rates of acceleration and deceleration, a maximum speed, etc. in accordance with the origin of the tr... | 12/10/1985 |
| 4538336 | Method of providing infinitely adjustable eccentric motion from a rotary motion This invention is a method and apparatus for quickly and infinitely adjusting the degree of eccentricity of a rotating member wherein a first rotating member is provided with interlocking means to a second member carrying means to rotate at an adjustable ... | 09/03/1985 |
| 4485693 | Eccentric-operated vibrating apparatus A vibrating apparatus e.g. for shaking the forming wire of a paper machine, comprising a body (1) and a drive shaft (2) rotatably mounted in the body. The drive shaft supports an eccentric bushing (3) displaceable along but nonrotatably fixed to said driv... | 12/04/1984 |
| 4311065 | Paper tape punch assembly The drive mechanism for a paper tape punch and reader assembly utilizes tape drive assemblies which move the paper tape in response to the application of continuous periodic motion and control signals. The periodic motion serves to oscillate a rocker plat... | 01/19/1982 |
| 4261228 | Stroke adjustment for reciprocating mechanism A stroke adjustment for reciprocating mechanisms which includes an external adjusting wheel to vary internally the longitudinal position of a carrier through an interconnected shaft and gear. A butterfly arm is pivotally connected to the power shaft and i... | 04/14/1981 |
| 4249424 | Variable throw eccentric The invention achieves a method and a device for providing infinitely variable adjustment to the throw of an eccentric from zero to a maximum while the eccentric is permitted to continuously travel in angular motion. This is achieved by two juxtaposed and... | 02/10/1981 |
| 4138904 | Link drive mechanism for mechanical presses A link drive mechanism for vertically moving the slide of a mechanical press comprises a power driven eccentric unit carried by a horizontal shaft arranged substantially vertically above the connecting means for the slide and having first and second adjac... | 02/13/1979 |
| 4022082 | Driving apparatus for oscillation of a mold within a continuous casting machine The present invention relates to a driving apparatus for oscillation of a mold within a continuous casting machine and includes an eccentric shaft, having an eccentric shaft portion, rotatably mounted upon a frame, and an eccentric sleeve mounted upon the... | 05/10/1977 |
