Patent number: 4881468Abstract: Described in a suspension conveyor system suitable for the use of conveyance units having two travelling rollers interconnected by an open yoke. The suspension conveyor system is universally applicable and capable of optimum adaptation to operating and space conditions in a given plant. To this purpose the system comprises changeover means selectively operable to tilt a conveyance unit to a left or right laterally suspended position or a center-suspended position to thereby permit for instance the radii of curved rail sections to be considerably shortened and particularly achieve a less complicated construction of required switches. In a preferred embodiment the switch is formed as an integral shaped member, so that the continuity of the rail circuit has not to be interrupted for guiding a conveyance unit onto selected branch rails.Type: GrantFiled: February 10, 1987Date of Patent: November 21, 1989Assignee: Veit GmbH & Co.Inventors: Josef Hafner, Werner Bergmeier, Rolf Schonenberger, Matthias Fischer

Patent number: 4870906Abstract: The invention relates to a dual track system for rail vehicles and magnetic vehicles. To enable this track system to be used in common by conventional wheel-and-track vehicles and magnetic vehicles, switches are needed by which both types of vehicle can be switched from a track on which only the one type of vehicle can run to a track which can be used by both types of vehicle. Furthermore, the switch must be suited for providing branches in a track on which both types of vehicles can operate. For the solution of this problem the invention provides a switch system which is essentially characterized by a flexible beam (6a) on which a likewise flexible track section (21) is mounted, which is intended for common use by rail vehicles and magnetic vehicles, and by an apparatus (31) for opening or closing a gap (30) between the beam and each such track (1a) to be traversed by the rail vehicles which permits the flexing of the beam.Type: GrantFiled: March 16, 1988Date of Patent: October 3, 1989Assignee: Thyssen Industrie AGInventors: Gottfried Schaffer, Gert Schwindt

Patent number: 4867071Abstract: An improved articulated connector or coupler in which the connection between the male connecting member and female connecting member via a king pin is provided with an elastomeric bushing housed in the male connecting member. The bushing has an outer metallic ring, and inner metallic ring, and a middle ring of elastomeric material, by which a coupling free of uncontrolled slack is achieved and by which all normal draft and buffing, as well as train-action and angling, forces, are damped and partially absorbed by the elastomeric ring. For excessive loads, in order to protect the elastomeric ring, over solid metal-to-metal stops are provided which shunt the force transmittal from the eleastomeric ring to metal stop-surfaces. The king pin is also frustro-conical in shape at the intermediate portion thereof passing through the bushing of the male connecting member, which bushing has a similarly-shaped frustro-conical passageway.Type: GrantFiled: April 13, 1988Date of Patent: September 19, 1989Assignee: National Castings, Inc.Inventor: Hans B.
