This invention relates generally to a device for removing risers or the like from metal castings. The device generally includes a frame on which there is mounted a power actuated means for fracturing and separating the riser from the casting and a retaining and locating means which serves to locate and retain the power actuated means in a position in which it is operative to strike the riser and separate it from the casting.

DETAILED DESCRIPTION In accordance with the present invention, there is provided a riser removal device for castings which overcomes the inefficient and hazardous method of riser removal encountered heretofore.
This is accomplished generally by transferring an increasing force from a hydraulic cylinder to the riser.
A locating means is also mounted on the frame and is constructed so as to fit or seat on a convenient structural element of the casting so as to position the actuating means for application of a fracturing force to sever or break the riser from the casting.
