Abstract
A mechanical grab consisting essentially of a frame within which round-bottomed scoops with straight-walled sides can be rotated about an axis in such a manner that, when the grab shuts, the mutually facing walls of the scoops are upwardly movable in overlapping relationship while the relative speed with which each of the scoops rotates about its axis is different.
Claims6
A mechanical grab consisting essentially of a frame, pivoting means mounted on said frame, two round-bottomed scoops with straight-walled sides pivotable on said pivoting means in such a manner that, when pivoting from an open position to a carrying position a pair of corresponding walls of the scoops in a separating position move together in overlapping relationship and then separate again, a pulley fixed to each scoop, one of said pulleys being smaller in diameter than the other so that the relative speed with which each of the scoops pivots is different.
