Patent number: 4660477Abstract: A work surface is mounted on a pair of brackets which are releasably mounted on and project outwardly in cantilevered relationship from a panel adjacent the opposite ends thereof. The work surface, in each end rail thereof, mounts a manually-actuated latching lever which is biased down into latching engagement with the respective bracket. The latching lever prevents the work surface from moving away from the panel and from being lifted upwardly adjacent its rear edge. The latching lever has the end thereof accessible from beneath the rear edge of the work surface so as to be manually moved upwardly to release the work surface from the bracket, whereupon the work surface can be slidably displaced outwardly away from the panel through a limited extent. When the work surface is manually slidably moved forwardly toward the panel, the latching lever automatically re-engages its respective bracket.Type: GrantFiled: August 17, 1984Date of Patent: April 28, 1987Assignee: Haworth, Inc.Inventors: Randall L. Kortering, Paul S. Gartland

Patent number: 4068577Abstract: A work supporting table has a carriage which extends beneath the bed of a press and a table top which extends over the bed. The carriage has wheels which rotate about eccentric spindles on the ends of the two axle shafts. Chains are wrapped around these shafts and forces are applied to the chains by an air cylinder mounted on the carriage. When the chains are drawn taut, the axles rotate such that the spindles move downwardly and cause the wheels to descend with respect to the carriage frame and thereby lift the table upwardly. The wheels when so disposed support the table with its table top slightly above the press bed. Conversely when the chains are released, the wheels move upwardly and the table top descends onto the press bed which supports it so that a force applied to a workpiece on the table top is resisted by the press bed.Type: GrantFiled: March 15, 1976Date of Patent: January 17, 1978Inventor: Patrick Joseph Murphy
