Abstract
A clamping device for clamping an object to a structure, the device including a lever arm pivotally mounted relative to the structure, at least one member for urging one end portion of the arm in a direction to pivot the other end portion into engagement with the object, and an actuator supported by the housing and adapted to engage the one end portion of the arm to pivot the other end portion out of the engagement. The device is utilized to clamp a screen to a bed of a separator.
Claims31
A clamping device for clamping an object to a structure, the device comprising a lever arm pivotally mounted relative to the structure, two springs extending to either side of the arm and connected to one end portion of the arm to apply a spring force to the one end portion in a direction to pivot the other end portion into engagement with the object, and an actuator supported by the housing and adapted to engage the one end portion of the arm to pivot the other end portion out of the engagement.
A separator comprising a bed comprising at least one wall;
- a screen supported in the bed;
- and a device for clamping the screen to the bed, the device comprising a lever arm pivotally mounted relative to the wall, two springs extending to either side of the arm and connected to one end portion of the arm to apply a spring force to the one end portion in a direction to pivot the other end portion into engagement with the screen, and an actuator supported by the housing and adapted to engage the one end portion of the arm to pivot the other end portion out of the engagement.
A separator comprising a bed comprising at least one wall;
- a screen supported in the bed;
- and a device for clamping the screen to the bed, the device comprising a lever arm pivotally mounted relative to the wall, two springs extending to either side of the arm and connected to the one end portion of the arm to apply a spring force to the latter end portion to urge the one end portion of the arm in a direction to pivot the other end portion of the arm into clamping engagement with the screen;
- and an actuator supported by the housing and adapted to engage the one end portion of the arm to pivot the other end portion out of the clamping engagement.
A clamping device for clamping an object to a structure, the device comprising a lever arm pivotally mounted relative to the structure, two compression springs extending to either side of the arm and connected to the one end portion of the arm to apply a spring force to the latter end portion to urge the other end portion of the arm into clamping engagement with the object, and an actuator supported by the housing and adapted to engage the one end portion of the arm to pivot the other end portion out of the clamping engagement.
A separator comprising a bed comprising at least one wall having an opening;
- a screen unit supported in the bed and extending within the wall;
- an arm extending through the opening in the wall and pivotally mounted relative to the wall, the arm having one end portion extending within the wall and adjacent the screen unit, and another end portion located outside of the wall;
- force-applying apparatus for applying a predetermined force to the other end portion in a direction to pivot the arm so that the one end portion engages the screen unit with a force proportional to the predetermined force;
- and an actuator adapted to selectively apply a force to the other end portion in excess of the predetermined force to pivot the arm so that the one end portion moves out of the engagement.
A method of clamping a screen relative to a bed in a separator, the method comprising providing an arm extending through an opening in a wall of the separator;
- pivotally mounting the arm relative to the wall;
- the arm having one end portion disposed adjacent the screen within the wall, and another end portion located outside of the wall;
- applying a predetermined force to the other end portion in a direction to pivot the arm so that the one end portion engages the screen with a force in proportional to the predetermined force;
- and selectively applying a force to the other end portion in excess of the predetermined force to pivot the arm so that the one end portion moves out of the engagement.
