Abstract: A flexible coupling for transmitting power and accommodating compound misalignment between shaft hub or tubular members. The coupling comprises an extended length of a given width of thin, resilient, high strength material provided with lengthwise corrugations and coiled freely on itself with meshing corrugations to a given radial thickness to constitute a hollow, laminated flexible element having annular, axially spaced corrugations extending between integrally flanged end portions for attachment to coaxial transmission members. The element is self-sealing and can be used to transmit fluid pressure between tubular interconnected members.

Abstract: The flexible mechanical coupling herein shown comprises a drive member, flange and internally notched barrel in rigid relationship. The flange is a part of a helically formed coil-like torsion spring. An externally toothed sleeve is in concentric relationship to the barrel with its teeth in loose engagement with the notches. The driven element and the sleeve and the end of the torsion spring remote from the flanged end are secured in rigid relationship. The reservoir within the barrel is filled with viscous damping fluid.

Abstract: An improved drive for use as between the engine and the clutch or transmission of a motorcycle and as between the clutch or transmission and the drive wheel. Instead of a metallic chain, a toothed timing belt of flexible or synthetic fabric material is used. The belt teeth of the pulleys on the shaft of the engine, on the shaft of the clutch or transmission and on the shaft of the rear wheel are machined to have a shape and configuration to adapt them to receive the teeth on the timing belt. The same type of belt is used between the engine and the clutch or transmission and between the clutch or transmission and the rear wheel. In the preferred form of the invention a sleeve housing is provided with peripheral teeth and of a shape to fit back over the clutch or transmission.

Abstract: A sealing device for a control lever extending through an opening in an element. Of an opening-surrounding sealing member, which is tightly secured to the control lever, a portion is by one end of a spring pressed into contact with an opening-surrounding guide groove in the element. The other end of the spring is connected to the device to be influenced by the control lever, thus allowing relative motion between the element and said device.

Abstract: A permanently sealed gear coupling for connecting a pair of substantially coaxially aligned rotatable shafts comprising a hub connected to each of the rotatable shafts, each of the hubs including outwardly extending spur gear teeth projecting from a portion of the outer surface thereof; a sleeve surrounding and radially spaced from each of the hubs, the sleeve having inwardly extending spur gear teeth in meshing engagement with the outwardly extending gear teeth on each hub; and permanently mounted sealing rings for retaining lubricant in spaces between the hubs and the sleeve for lubricating the meshing gear teeth.

Abstract: Herein disclosed is an elastic coupling using rubber or an elastomer as an elastic element. The elastic coupling includes an inner metal ring having its radially outer surface radially curvilinearly convexed, an outer metal ring having its radially inner surface radially curvilinearly convexed, and an elastomer ring interposed between the inner and outer metal rings and having its radially inner and outer surfaces correspoindingly radially cirvilinearly concaved as to be fitably secured, respectively, to the outer surface of the inner metal ring and to the inner surface of the outer metal ring. Thus, the modulus of shearing strain of the surface portions of the elastomer ring at the side is smaller than that of an inside portion of the same so as to eliminate any pretension of the surfaces of the elastomer ring.

Abstract: A pushbutton system for a car radio receiver, comprising pairs of selector drive rods alternately engaged by a common button. A pawl drives a sequencing catch. The pivot point of the pawl is shifted when re-setting a drive rod so that sequencing is inhibited. The pivot point is restored to normal only upon full depression of the button.

Abstract: A resilient drive comprises rotary driving and driven members interconnected by a resilient coupling. The coupling comprises a pair of coil springs and a plurality of spherical balls abutting the springs in circumferentially disposed relationship therewith. A pressurized fluid, such as oil, is continuously communicated to the coupling to aid in the damping function thereof.

Abstract: Axial retention of the drive shaft is provided in a fluid pressure device of the type including an internally-toothed member, an externally-toothed member disposed eccentrically therein for relative orbital and rotational movement, and a drive shaft extending into a central bore defined by the externally-toothed member. The drive shaft has male splines and the externally-toothed member has female splines in the central bore, engaging the male splines. The front face of the externally-toothed member has a recess including a stop surface generally perpendicular to the axis of the device and the drive shaft has a shoulder extending radially outward and engaging the stop surface to limit the axial movement of the drive shaft into the central bore. Wear is minimized because the mating stop surface and shoulder are rotating at the same speed and, preferably, the shoulder "nutates" with respect to the stop surface.

Abstract: This invention relates to a vernier drive mechanism, in which a vernier shaft always being subjected to the elasticity of a coil spring is put into a hollow part of a main shaft in a freely rotatable manner, a housing is put outside the main shaft also in the freely rotatable manner, a part having a hexagonal section or a shape causing the similar effect is made at the center of the main shaft, holes open to the hollow part of the main shaft are made on the three planes placed radially at the same angle of the six peripheral planes, balls are put into the holes and are made to contact with a small diameter part of the vernier shaft and the inner surface of the housing by the elasticity of the spring so as to rotate planetarily by the rotation of the vernier shaft and to turn the main shaft at a speed slower than that of the vernier shaft.

Abstract: A support assembly of the vertical rotor comprises a drive shaft connected with the rotor shaft by means of an elastic support which provides the rotor with self-centring in the course of its rotation.This support is formed by two groups of elastic components viz., radial and axial ones, interconnected by a rigid component and having independent flexibility coefficients in the appropriate directions.

Abstract: A centrifugal pump assembly for use in nuclear reactor plants has a vertical motor shaft, a vertical pump shaft which is coaxial with and is located below and spaced apart from the motor shaft, an intermediate shaft which is coaxial with and is located between the pump shaft and motor shaft, a flexible coupling between the lower end of the motor shaft and the upper end of the intermediate shaft, and a rigid coupling between the upper end of the pump shaft and the lower end of the intermediate shaft. The intermediate shaft is rotatable in radial and/or axial bearings which are installed in a stationary housing, and the intermediate shaft is movable axially of the housing between a lower end position in which the rigid coupling is engaged and a raised position in which the rigid coupling is disengaged and the bearings and/or seals for the pump shaft are accessible.

Abstract: A clutch construction comprising inner and outer relatively rotatable members, and a flexible friction band interposed between said members. A plurality of separate elements are interposed circumferentially between the band and the inner member in abutting engagement with one another and otherwise being independent of each other. Force applying means is provided and is operable in response to rotation of one of said members to act on said elements and urge them radially outwardly and circumferentially to maintain said elements in abutting engagement not withstanding said radially outward movement thereof. After engagement, and upon overrunning by the other member or upon reduction in the speed of rotation of the one member, disengaging means on the one member acts on the band to disengage the drive.

Abstract: Upon pushbutton depression, a face in the key slot of a button slide forcibly engages the T lug extending from a tuner slide, thereby translating the tuner slide. Coupled to the tuner slide is a memory cam the angular position of which is presettable, corresponding to a desired receiver tuning. The cam is forced to engagement with a tuning mechanism which senses the angular position of the cam and tunes the receiver accordingly. The face is predeterminedly curved, and the vertical height of the slot so dimensioned, to decouple vertical deflections of the button slide from the tuner slide, thus minimizing deviations of the cam from its preselected position. When mounted in a chassis, the chassis is provided with a guide detail which further minimizes vertical deflection of the tuner slide.

Abstract: A reproduction machine having a document scanning system has an improved recycling clutch for operating the system. The clutch has a rotatable input plate and a rotatable output plate. An annular pawl plate pivotally mounted on the input plate has a driving surface which is biased into engagement with a pin on the output plate. A rotatable timing element driven by the input plate periodically contacts a cam surface on the outer periphery of the pawl plate to disengage the driving surface from the pin to effect release of the clutch at intervals greater than a revolution of the input plate. The cam surface maintains the disengagement of the driving surface from the output plate for a sufficient length of time to permit rotation of the latter in the reverse direction greater than one revolution via a biasing spring.

Means are provided for setting of the locator to a desired position. An actuator is operable either to move the reference to store a set position of the locator or to move the locator to take up a pre-set position stored by the reference.

Abstract: A friction clutch for a power driven element such as a rotary blade in which the element is seated on a drive shaft having a flange and an adjacent thread having an associated nut. Adjacent the driven element is a washer assembly which includes a rubber washer and a Bellville washer having its concave side faced toward the rubber washer so as to develop frictional clutching force between the shaft and the power driven element as the nut is tightened, the concavity of the Bellville washer serving to confine the rubber washer against radial expansion and the rubber washer, by its confinement, serving to prevent collapse of the Bellville washer upon severe tightening of the nut.

Abstract: A constant velocity universal joint for transmitting motion between two shafts which are intended to be run at an angle. An even number of spindles preferably equal to, or greater than, four are mounted on a hub member fixed to one of the shafts. Rollers with part-spherical outer rolling surfaces are slidably and rotatably mounted on the spindles and cooperate with corresponding opposed pairs of grooves formed in a cup member fixed to the other shaft. The angle formed between the longitudinal axis of one of the spindles with the axis of its respective shaft being equal to the angle formed between the longitudinal axis of its corresponding pair of opposed grooves and the axis of the latter's respective shaft. This angle between 15.degree. and 45.degree. may differ from one spindle and its pair of opposed grooves to another such unit.
