Abstract:
1. A clamping device for use in association with a fluid collecting container having a vertically-extending wall with a top edge, and for securely mounting a float switch housing and micro switch in a variety of fixed locations relative to the wall, so that when fluid accumulating in the container exceeds a predetermined depth considered safe, the deployable end of a float body pivotally secured within the housing will be raised a sufficient amount to activate the micro switch and cause it to generate a shut-off signal that is then sent to the system providing fluid to the container to stop fluid production, said clamping device comprising: unitary structure having a clamping member connected via a bridge to two rail plates positioned in back-to-back orientation one to the other, said bridge having opposing ends and said clamping member depending from one of said opposing ends in perpendicular association with said bridge, said two rail plates depending from the other of said opposing ends of said bridge in a position where a portion of said bridge extends between said two rail plates; said clamping member having an inverted U-shaped configuration, an open-ended slot extending vertically through said inverted U-shaped configuration, and at least two threaded openings extending through the portion of said inverted U-shaped configuration remotely located from said bridge, said open-ended slot also having a closed top end, and said threaded openings also being configured and positioned for communication with said slot; each said rail plate having a vertically-extending channel with an open top end, said channel also having an open-front configuration facing away from the other one of said rail plates; and at least two fasteners each having threads configured for allowing secure engagement with a different one of said threaded openings associated with said clamping member, so that when said clamping member is positioned over the top edge of the vertically-extending wall of a fluid collecting container with said slot aligned with the top edge, and said bridge and said two rail plates are also placed into an orientation where they will be located within said fluid collecting container when said clamping member attains its desired position of use relative to the wall, and subsequently when said clamping member is lowered over the wall's top edge so that the top edge becomes inserted into said slot and lowering continues until the wall's top edge comes into contact with said closed top end of said slot and a portion of the wall below the top edge also becomes positioned within said slot, said at least two fasteners can each be advanced through a different one of said threaded openings in said clamping member until contact is made with a portion of the wall within said slot, with said at least two fasteners thereafter being tightened to fix said clamping member securely against the wall, and then if a float switch housing having a pivotally-deployable float body is placed in fixed association with said vertically-extending channel of one of said rail plates, the housing attains a parallel orientation to the wall that positions a lateral portion of the deployable end of the float body close to the wall, wherein even a small amount of fluid accumulating in the lowermost corner of the fluid collecting container when it is in a tilted orientation is able to cause upward deployment of the float body and generation of a shut-off signal to stop fluid production in the system responsible for providing fluid to the container.
