Abstract: A portable dock of sectional construction in which adjoining dock sections may be connected together by a pivot arrangement which allows the attachment of one dock section to the other without entry into the water over which the dock assembly is to extend. The pivot arrangement supports the dock section being added for pivotal movement from a prior installed dock section to a horizontal position extending in cantilevered relationship to the prior installed dock section. The pivot arrangement includes supporting surfaces which limit the extent of pivotal movement of one dock section relative to the other and also act to support the added dock section in cantilevered relationship.
Abstract: A visor assembly incorporating a visor having a built-in lighted vanity mirror which is illuminated in one embodiment by movement of a mirror cover and in another embodiment by movement of the visor from a storage position to an operative position. The lighting system serves to illuminate an object such as an observer or a map with a light intensity that can be varied manually.
Abstract: A carburetor and fuel feed device for small internal combustion engines incorporating a pumping section which receives fuel from a supply and delivers the required amounts for the range of operation between high and low speed operation with any excess being returned to the source of supply. A control device is employed which permits deceleration from high to low speed operation without flooding by instantaneously preventing the supply of fuel for high speed operation in response to movement of the throttle valve to an idle or low speed position.
Abstract: A wheel and grease cap combination in which a plastic covered portion on a vehicle wheel is provided with a radially inwardly facing annular groove positioned adjacent to an opening in the wheel for receiving the grease cap and radially inwardly of the bolt circle for receiving bolts to attach the wheel to the axle hub. The groove receives a plurality of attaching means formed on the grease cap which deflect radially inwardly upon attachment and detachment of the grease cap. The attaching portions firmly engage the bottom of the groove to prevent both axial and rotational displacement of the grease cap relative to the wheel.
Abstract: A carburetor has a choke control device that acts in connection with a thermoplastic control to permit the carburetor choke valve to be closed during starting but provides a controlled gradual opening of the choke valve after starting. The device includes a self-cleaning purge feature for continual cleaning of the device. A simple one way choke valve device and precision by-pass give exact control of the choke opening. A back pressure valve is provided to prevent back fire damage to the unit.
Abstract: A wheel trim assembly for an automotive vehicle wheel in which a retaining member is adapted to support either a decorative wheel cover or wheel ring and is provided with retaining devices so disposed on the retaining member that when the trim assembly is attached to the wheel of the vehicle, portions of the retaining devices are disposed at an angle to the tire supporting flange of the wheel so that both axial and rotational displacement of the trim assembly relative to the wheel are prevented.
Abstract: A wheel trim assembly in which retaining devices are circumferentially spaced to engage and grip an annular lip portion at the outer circumference of a vehicle wheel and in which each of the retaining devices has a pair of circumferentially spaced wheel engaging portions which may flex independently of each other to accommodate variations in both the wheel and the wheel trim assembly.
