Hydraulic hose lines between an inner rail and an adjacent outer rail of a lift truck mast are reeved within a hollow chain guideway. Opposite ends of the chain are fixed to vertical channels; one channel is mounted to the outer rail and the other, to a center support of the inner rail, with the lowermost portion of the chain looped between the channels. The distance between the chain portions seated in each channel provides an unobstructed operator viewing window. Elevating the inner rail causes the chain to progressively separate from the outer rail channel and engage the inner rail channel while lowering of the inner rail causes the chain to separate from the inner rail channel and engage the outer rail channel.

A dual axis carriage assembly for industrial control handles includes a base yoke fixed to a support surface and a moveable yoke to which the control handle is attached. Each yoke includes a pair of coaxial spaced bearing surfaces and journal portions of one shaft of a cross shaft assembly are received in the bearing surfaces of the moveable yoke while journal portions of the other shaft are received in the bearing surfaces of the base yoke. A torsion coil spring is carried on each shaft with the spring having a pair of parallel arms which straddle the sides of a flange projecting from the yoke within which the corresponding shaft is received. A dog, fixed to the end of each shaft includes an axial leg which is positioned between the spring arms. Rotation of each shaft relative to its yoke results in displacement of one spring arm so that the spring returns the shaft to a null position. The dog also includes two radial legs which engage the yoke flange to provide rotation limit stops. An angular displacement transducer and includes a body fixed to each yoke and a stem which is received in an axial bore of the corresponding shaft to generate a signal representative of angular displacement of each shaft with respect to a reference position.

A method for handling conventional stacks of baked goods trays for the baking industry. A platen is moved underneath side-by-side stacks of trays. The platen supports the underside of the stacks of trays and prevents lateral movement of the bottom of the stacks by guiding the platen into channels that exist in the bottom of the trays. The platen is attached to an upright which is tiltable and which extends along one side of the baked goods trays when on the platen to support the stacks along their vertical height. Tilting of the upright causes the platen to lift and the trays to tilt against the upright where they are supported underneath and along the side and thus can be moved and handled. By utilizing the split platen and the tall tiltable upright with a motorized vehicle, an economical and efficient method of handing baked goods tray stacks is possible, eliminating significant manual labor and risk of worker injury.
