ABSTRACT:
A manually manipulatable device for adjusting the position of a workpiece supported on a machine having relatively movable parts operated by electrically controlled, selectively energizable and deenergizable driving means comprises an elongate arm having a workpiece engageable fork at one end and a support at its other end for manipulation by an operator. The support preferably is pistol-shaped having a grip at one end and a barrel at its other end. The support includes two normally open, manually closable electrical switches in circuit with the machine's driving means to effect energization of the latter under the control of the workpiece manipulating device, but only when both of the switches are closed. The switches are spaced apart from one another a distance greater than that which can be spanned by the fingers of one hand of the operator, thereby preventing closing of both switches unless the operator's hands are on the support. The workpiece engageable fork and the support are spaced apart a distance sufficient to ensure that, when the fork engages the workpiece, the support is spaced from the machine a distance sufficient to ensure that the machine operator's hands are outside the machine.
