ABSTRACT:
This invention relates to a work hook device which is particularly constructed for supporting castings as they are conveyed through a blast cleaning machine. The work hook device includes a suitable support which is of an inverted keystone cross section and which has mounted thereon one or more hooks, each of the hooks including a hanger portion and a hook portion, and the hanger portion having an opening therethrough for receiving the support, and an upper portion of the opening being of a tapered configuration for interlocking engagement with the support. The construction is such that each hook may be mounted on its associated support in a desired angular relation as opposed to being vertically disposed and so locked in that position so as to rigidly engage a workpiece to be cleaned. Normally a pair of hooks will cooperate with one another to carry a relatively large casting. Each support may be carried by a rotatable shaft so as to rotate the casting during the blast cleaning operation.
