    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.

    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. A bore extends into the rear end of the handle between the flanges and a spring is disposed in the bottom of the bore and urges a plunger against the front edge of the rib. The rib includes a plurality of recesses in which the plunger may be frictionally held.
