  • Patent number: 5857933
    Abstract: A phased chain and sprocket assembly is provided in which the pitch length of the chain is not matched to the pitch length of the sprocket. Specifically, the chain link pitch length is approximately twice the pitch length of the associated sprocket teeth. By providing two chains in side-by-side, but offset relation, a phased chain and sprocket assembly can be achieved without the need for circumferentially offset sprockets.
    Type: Grant

  • Patent number: 5779582
    Abstract: The chain guide of the present invention, which will be utilized on the tight side of the chain of an engine system, is designed to reduce the lateral motion of the chain. The chain guide is constructed with raised side rails that taper inward to the center. The slot which guides and controls the chain gradually narrows towards the center.

  • Patent number: 5720683
    Abstract: A mechanical tensioner having a piston biased by a spring in a protruding direction. A ratchet assembly includes a spring, a ratchet piston, and a pair of ratchets may also provide a no-return function. A plurality of belleville disc springs provides the force on the tensioner piston, the ratchet piston, or both.

  • Patent number: 5603482
    Abstract: A solenoid valve mechanism including a valve housing with a vent port and a pressure supply port, a ball valve in a valve seat in said housing controlling pressure distribution to a control pressure passage from the supply port, a solenoid armature adapted to activate the ball valve, and a spring valve seat that cushions the operation of the valve mechanism when it is activated. Other mechanisms for reducing vibrations and noise of a solenoid valve mechanism include Belleville springs, O-rings, coil springs, foam cushions, and the like. The valve mechanism can be either normally applied or normally vented.

  • Patent number: 5074004
    Abstract: An apparatus including a buoyant housing including a rotatable brush directed longitudinally through a forward opening of the housing, wherein the housing includes a sealed battery and motor for selective actuation of the brush. An angulated handle is directed forwardly and spaced above the housing and arranged at a relative acute angle to a top surface of the housing to permit an individual to direct the brush about a forward surface of a swimming pool apron. A modification of the instant invention includes a plurality of spaced buoyancy members mounted adjacent sides of the housing to permit adjustment of the housing relative to an associated water level within a swimming pool.
