Abstract : A grabber type cylindrical object recovery apparatus is provided wherein the grabber has a U-shaped frame which is curved substantially 180 deg. A pair of curved pads are provided wherein each pad is pivoted to a lower extremity of a respective leg of the U-shaped frame. The inside of the curves of the pads face inwardly with respect to the cylindrical object. In the releasing position a top portion of each pad extends slightly into an open area within the frame so as to be located for forcible engagement with a top portion of the cylindrical object and then pivotal movement for the grabbing position when the object is encompassed by the U-shaped frame. In the grabbing position the bottom portion of each pad extends the curve of the respective leg beyond the 180 deg of the frame so as to engage a bottom portion of the cylindrical object for retention purposes. A pair of locking devices is provided wherein each locking device is mounted to the frame for locking a respectively pad alternately in its releasing position or its grabbing position. The locking devices are responsive to the forcible engagement of the cylindrical object with the pads to change the locking devices from a locked released position of the pads to a locked grabbing position of the pads.
