Rotary To Gyratory Patents (Class 74/86)
  • Patent number: 4757722
    Abstract: A mechanism is disclosed for transforming reciprocating/rotating motion in which the reciprocating member is continuously rotated unidirectionally so as to perform 360 degrees of rotation over the course of each cycle of reciprocity, into any number of simultaneous arcuate motions intersecting at predetermined angles. This mechanism comprises a ball rotatably mounted by a supporting element and centered on a line which is perpendicular to the path of excursion of the reciprocating member at the midpoint of the excursion, which line coincides with the axis of rotation of the reciprocating member at the midpoint position, and a linkage(s) provided to transfer the motions of the reciprocating/rotating member(s) to the ball. Points on the surface of the ball are thereby made to exhibit an infinite number of arcs which intersect a common point at an infinite number of angles.

  • Patent number: 4715733
    Abstract: A thrust bearing for use between two parallel plates in relative orbital motion. The bearing includes a plurality of rollers disposed between the plates. Each roller comprises two opposing cones joined at their base with one cone in rolling line contact with one plate and the other cone in rolling line contact with the other plate. As one plate orbits relative to the other, each rolling line contact sweeps a circular area on its respective plate.

  • Patent number: 4561346
    Abstract: A device is disclosed for oscillating and vibrating a deep pan so that the contents in the pan are thoroughly and evenly cooked without the chef's continual attention. The device is moved back-and-forth via a lever arm connected to a rotating disc. The lever arm is connected to the disc by a lost-motion connection, in the first embodiment of the invention. In the second embodiment, the plate supporting the frying pan is moved back-and-forth via a crank arm pivotally connected to the disc, while the other end of the crank arm is pivotally connected to a connecting link, which is attached to the underside of the support plate. Rollers mount the support plate for movement, and may allow for compound movement of the support plate when casters are used. The compound motion is generated by mounting the rotating disc in a plane offset from the horizontal and allowing sufficient play to the rollers mounting the support plate.

  • Patent number: 4555183
    Abstract: A laboratory mixer includes a test tube supporting cup means that translates in a circular path at high speed without rotating thereby creating an effective vortex in the materials in the test tube. A motor is mounted in the apparatus housing and supports a cylindrical metal block. The cylinder includes a circular cavity having a center located away from the axis of rotation of the motor and the cylinder itself. A pair of bearings located in the cavity support one end of a shaft that carries the test tube holding cup. The cup is allowed to translate in a circular path but is prevented from rotating by a restraining means that includes a restraining arm rotatably attached to the housing and a side arm connecting the restraining arm to the cup supporting shaft. The user rests the heel of his hand on a pressure sensitive touch plate while placing the closed end of the test tube in the cup. Pressure from the hand causes the touch plate to close a switch and automatically turn the mixer motor on.

  • Patent number: 4440004
    Abstract: A vertical axis flow through type clothes washing machine with a basket driving transmission which imparts a wobble action to the basket during wash and conventional rotational motion during spin operations. The transmission supports the basket such that when the input drive shaft rotates in its wash direction, the central basket axis is canted relative to the substantially vertical axis of rotation of the drive shaft. As the shaft rotates, the central basket axis describes an inverted cone thereby imparting the wobble action to the basket which is prevented from rotating about its own axis. When the drive shaft rotates in the opposite direction for spin, the central axis of the basket is substantially coaligned with the vertical axis of rotation of the input drive shaft, and the basket is rotated about its own axis for centrifugal extraction of liquid from the clothes in the basket.

    Abstract: A thrust bearing/coupling component for use in scroll-type apparatus which may be a compressor, expander, fluid pump or vacuum pump. The resulting apparatus is particularly suited for use as auxiliary equipment in automotive power systems. The component of this invention comprises rotating or oscillating load carrying members, preferably ball bearings, confined within facing indentations cut in the orbiting scroll member end plate surface and an associated surface in a member stationary with respect to the orbiting scroll member. The thrust bearing/coupling component couples the stationary and orbiting scroll members in a predetermined angular relationship and it may be used to carry either expansive or compressive axial loads on the scroll members to achieve efficient radial sealing of the moving scroll fluid pockets while controlling surface wearing so that the scroll apparatus may be operated for an extended period of time without servicing.

  • Patent number: 4254861
    Abstract: An elongated conveying device suitable for connecting spaced work stations, for example, receives a flow of objects such as component parts at an appropriate entrance. The objects are placed on a pair of spaced stationary rails from which the objects are lifted, carried forward and then returned to the stationary rails by a pair of movable rails which is rotated in a circular-shaped cycle. With each cycle of the movable rails, the objects are stepped from the entrance to an exit located some distance away. Because the rate of object input may vary from the rate of part discharge, the conveying device may include holding stations adjacent to the exit allowing the objects to accumulate in a damage resistant manner until removed from the conveying device.

  • Patent number: 4158845
    Abstract: A low-cost mechanical pointing and tracking platform that does not use gimbals and to which a sensor may be attached for use in searching an area for a target located at some unknown point. This is achieved with the use of a shaft, mounted intermediate its ends in a ball and socket joint and carrying at its forward end a platform for mounting a sensor. The other end of the shaft passes through a radial slot in a first rotatable member and extends into a spiral groove in a second rotatable member coaxial with the first. By manipulating the rotation of the two members, the sensor can be made to scan a circular, conical, spiral, linear or any other fixed or programmed complex pattern, can locate a target at any point in a two-dimensional field of view and can be made to track a target once it is detected.

Either the moving member or the stationary member is constrained in that it has only two degrees of freedom to rotate. Any moving point on the moving member can be made to perform useful work while it moves in a more complex pattern. A representative embodiment will convert a one-dimensional, sliding motion or a circular motion into a three-dimensional motion, the moving end of the moving member having attached thereto a spray-paint nozzle, which sprays paint in a three-dimensional pattern.

  • Patent number: 4061315
    Abstract: A platform or tray for holding laboratory containers such as test tubes is driven in orbital motion by an eccentric drive mechanism housed in a cabinet. First and second pairs of tracks are mounted respectively beneath the tray and to the top of the cabinet. An intermediate plate holds four disc-shaped, low-friction bearing elements, each coupled to and guided by an upper and a lower track to maintain said tray in the same disposition during its orbital motion. An electronic circuit controls orbital speed in a continuous manner over the operating range, even at low speeds. The system operates in either a continuous mode or timed mode under control of a switch. The motor which drives the platform also drives a dc motor, the terminal voltage of which is displayed as a signal representing the speed of operation. Both the speed and the time (in timed mode of operation) may be controlled by the operator. A vibration-free mounting system is used to secure the main motor and drive train within the cabinet.
