摘要： Method and apparatus for a safety lock assembly for a cam lock fitting mounted onto the outside of the cam lock fitting in close proximity to the cam levers to prevent complete separation of the male and the female portions of the fitting to prevent inadvertent pressurized discharge of dangerous materials. In one embodiment, this is accomplished by having slidable bosses upon which the cam levers are mounted which bosses are adapted to slide in response to movement of a safety handle so that the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. In a second embodiment, an earless cam disk moves on slotted, fixedly mounted bosses in response to movement of a safety handle similarly to the first embodiment.

摘要： A method and apparatus for an improved safety cam lock fitting having side by side double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on the inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space therein between. A lever latching mechanism may be used to prevent the cam levers from being inadvertently opened.

摘要： Method and apparatus for an improved camlock fitting having outer/inner cam lever which are restrained against unintended opening or rotation by a pivoting locking member which is pivotally mounted onto an axle disposed in a corresponding hole on the cam levers so that the pivoting locking member can be easily pivoted in the vertical plane relative to the cam arms. Each of the outer and inner arms has a pivoting locking member mounted on its underside in a protective housing. The camlock fitting may also have an air vent. Together this provides a safety lock assembly for the cam lock fitting so that when the cam lock fitting is pressurized unbeknownst to the operator and the operator attempts to open the cam lock fitting, the safety lock assembly will prevent operation or complete separation of the male and the female portions of the fitting to prevent inadvertent pressurized discharge of hazardous materials.
