Abstract

152,192. Wheatley, J., and Riddle, F. J. Sept. 24, 1919. Lifting-dogs.-A lifting-dog for manipulating ingots &c. has a pair of jaws e pivoted to slotted side frames c slidable on a bar a to which the upper arms of the jaws are connected by a pin k passing through the slotted frames. The jaws are disengaged from the load by lowering until the ingot raises the side frames sufficiently to engage a catch m which locks the jaws in the open position.
