ABSTRACT:
Various forms of mounting devices for mounting workpiece gripper carrying spreader bars upon a boom of a transfer device are disclosed. The boom is formed within an undercut T slot which extends the length of the boom and slidably receives a retainer member. A base spans the slot and is clamped to the side of the boom by clamping screws threadably received in the retainer member so that the base and retainer can be fixedly clamped to the boom at any selected location longitudinally of the boom. A recessed clamp member cooperatively defines within a recess in the base the socket of a ball and socket joint. In one form of the device, the same clamping screws which clamp the base to the boom simultaneously clamp a spherical coupling member fixed to a spreader bar and received in the socket in a selected fixed angularly adjusted position between the clamp member and base. In another form of device one set of clamping screws clamps the base and retainer to the boom and a second set of clamping screws are engaged between the clamp member and base. The coupling member may take the form of an annular split ring resiliently clamped to the spreader bar or may take the form of a spherical enlargement formed on the spreader bar.
