A manually activated suction lifting device has a handle which rotates up to complete an active suction. The first stage of the suction is created by pushing firmly down on the convex top of the device. Upon creation of the final suction with the handle locked up, an alarm button is drawn into the housing, hiding an alarm ring. If the suction fails, then a vent tube transmits the lost vacuum to an alarm chamber, thereby allowing a spring to bias the alarm button outbound, exposing the alarm ring to a worker so he can grab the workpiece and prevent damage...


1. A suction device comprising: a base forming about a half sphere having a convex top adapted to fit the shape of a palm of a human hand so that the suction device can be pressed against a workpiece by the palm of a human hand,a suction cup connected to said base, the suction cup including a piston therein,a piston rod in said base and connected to the piston,a cam adjacent the base and pivotally connected at one end to said piston rod, so that when said cam is rotated in one direction, said piston rod moves said piston and increases the vacuum in said ...
