  • Patent number: 5720071
    Abstract: An implement for cleaning cooking grates. The cleaning implement has an elongated handle and a head including teeth. The teeth are adjustably secured to, and spaced laterally along, the head so as to fit in between the staves of a cooking grate. The teeth are laterally movable so as to be adjustable to a particular cooking grate. A preferred embodiment has a slot to provide for lateral movement of the teeth. One embodiment envisions use of tapered teeth for contacting the grate staves along a tapered region. One embodiment employs an ergonomic handle allowing for cleaning with only a horizontal back and forth motion.

  • Patent number: 4066285
    Abstract: An extruded aluminum channel is formed with a wide central T-shaped groove and narrower outer T-shaped grooves transversely spaced on opposite sides of the central groove. A resilient vinyl bumper insert is formed with T-shaped in section projections which interlock in the outer grooves of the channel thereby securing the bumper to the channel. End caps are formed with tapered tangs which tightly fit into the central groove of the channel thereby securely fitting the end caps to the opposite ends of the channel. The ends of the channel and the corresponding end caps may be either square or slanted. The tangs of the end caps are formed with holes for fasteners such as pop rivets which extend through the holes in the tangs and also through registering holes drilled in the channel to attach the trim strip to a motor vehicle.
