  • Patent number: 5636814
    Abstract: A clutch for an interior latch handle of a plug-type airplane door is described which decouples the handle from the latch-operating linkage so the handle will not be backdriven into the passenger space when the exterior latch handle is operated to open the door from outside the airplane. The clutch includes a probe mounted on the base of a handle mechanism assembly in line with the handle, and a pawl pivotally mounted in the handle and disposed to engage a lug splined to the handle shaft and torsionally coupled to the latch. When the handle is in its "home" or "closed" position, the probe engages a roller on the end of an arm connected to the pawl and rotates the pawl away from the lug so that the handle shaft will not backdrive the handle into the passenger space when the exterior latch handle is operated to unlatch the door. When the handle is moved away from the probe, the pawl engages the lug to establish two-way torsional coupling between the handle and the latch.

  • Patent number: 5478094
    Abstract: An in-line skate has a wheel mounted on a rocker arm so as to be pivotable toward and away from the main platform. The pivoting is restrained by a compression spring whose pre-load is adjustable with a screw arrangement. A fixed brake pad depends downwardly an adjustable distance from the main platform in the vicinity of the rocker arm mounted wheel. As the user tilts the platform the rocker arm and its associated wheel are pivoted toward the fixed brake pad. When the wheel contacts the brake pad, further tilting pressure arrests the wheel rotation and thus generates a frictional braking force between the wheel and the support surface.

  • Patent number: 5472220
    Abstract: The present invention includes a dolly with an upwardly extending edge about 3 to 5 inches high, that generally conforms to the size of a standard five gallon bucket. The purpose of the invention is to be able to push around whatever materials one is working with, without having to pick the bucket up to move it. The upwardly extending edge on the dolly prevents the bucket from tipping as it is being pushed or pulled. Also, additional wheels can be added to distribute the weight load more evenly, and the wheels can be raised or lowered to lower the center of gravity, to help avoid tipping of the bucket within the dolly. The dolly can be used by a person sealing a driveway with a five gallon pail bucket. Painters or spacklers can also benefit from the bucket dolly. Spacklers can stack pails on top of each other as they normally do so that they can reach into the uppermost pail and move their materials around without reaching down and getting down out of their elevated stilts or scaffolds.
