  • Patent number: 8267819
    Abstract: A tensioner having a backstop device which allows free rotation of the pivot arm in a first direction but controls rotation of the pivot arm in a second, opposite direction. The backstop device permits a predetermined, limited amount of free rotation in the second direction and thereafter, employs a braking device to prevent rotation in the second direction if the torque that acts on the pivot art is less than a predetermined threshold.
    Type: Grant

  • Patent number: 7507172
    Abstract: A tensioner (10) features a backstop device (40) which allows free rotation of the pivot arm (20) in one direction but not the other. Reverse rotation is prevented by friction that is able to resist torque on the pivot arm (20) under ordinary operating conditions which otherwise could permit belt tooth-skip to occur. In disclosed embodiments, the backstop device (40) includes a stop sleeve (50) and a clamp holder (60) which are axially interlocked and are able to rotate relative to each other. A clutch spring (80) surrounds permits relative rotation between the stop sleeve (50) and the clamp holder (60) in one direction but not the other. A clamp (70) retained within the clamp holder (60) frictionally engages the pivot shaft. A viscous coupling may be used in place of the frictional clamp.

  • Patent number: 4098488
    Abstract: An automatic dispensing nozzle of the type for dispensing liquid such as gasoline, or the like, into a container and for automatically shutting off when the container is full. The assembly includes a housing having a fluid inlet and an outlet with the fluid passage extending therebetween and a valve disposed in the passage with a valve actuating stem extending exteriorly of the housing. A handle guard including a downwardly extending guide portion and a forwardly extending guard stem. A handle is pivotally supported at a front end adjacent the connection of the handle guard to the housing and extends to a rear end disposed adjacent the guide portion of the handle guard and engages the valve actuating stem for moving the valve actuating stem upon pivotal movement of the handle. The guide portion of the handle guard includes a forwardly extending rib and the rear end of the handle means is bifurcated to define flanges disposed on either side of the rib.
