Abstract: A collapsible work horse has legs pivotally mounted to opposing surfaces of a support beam. The legs are secured in the extended position by a two-part locking arrangement. In one non-limiting embodiment of the invention, a first part of a locking arrangement is mounted to each of the first ends of the legs adjacent the pivot point of its respective leg, and a second part of the locking arrangement is mounted to the supporting member. When the legs are in the extended position, the first and second parts of the locking arrangement engage one another to securely fix the legs in the extended position. In another non-limiting embodiment of the invention, a plurality of work horses are assembled with a tool support and work piece supports to provide a work station. The tool support and work piece supports are designed to be fixable in a compact storage arrangement.

Abstract: A magnetically actuated proximity switch is provided with a double-pole double-throw contact arrangement. To substantially equalize the contact pressures between the two poles a movable armature, to which the movable contacts are firmly attached, is loosely pivoted to rotate about a transverse axis to open or close the contacts and to rock about a longitudinal axis to divide the available operating force between the two poles of the switch.

Abstract: A magnetically actuated proximity device or switch is provided with an armature formed as a shallow U that is pivoted at its center and arranged with the legs of the U directed toward the pole faces of a pair of permanent magnets. The particular shape increases the sensitivity of the device and the force available for operating contacts or other output devices in response to the diversion of flux from an end of the armature.
