Patent number: 5104040Abstract: Apparataus for butt joining hanging conveyor supports having a C-shaped rail section in which conveying hangers can travel back and forth along the rail section. The supports each have a hollow section above the rail section and trolley wires running along at least one vertical side of the supports. Connecting parts are disposed between ends of adjacent supports, the hollow section having at least one profiled section in the shape of a square standing on a point. A square tube connects the ends and bridges the connecting parts and are inserted into the profiled sections at the ends of adjacent supports. Tie rods connect the ends of the adjacent supoorts. At least one L-shaped angle iron is disposed on each of the top sides of the ends of adjacent supports. The angle irons are connected to one another via at least one screw bolt and act, on both vertical sides of the ends of adjacent supports, on the tie rods which connect the ends together.Type: GrantFiled: March 30, 1990Date of Patent: April 14, 1992Assignee: Wampfler GmbHInventors: Uwe Bormann, Dieter Goerner

Patent number: 5009168Abstract: A track expanding device is employed in a conveyorized transport system to spread apart adjacently disposed sections of track thereby tensioning an endless chain travelling with these track sections. The expanding device comprises a splice and an expander having a threaded member for engaging with the splice with each of the splice and the expander being connected to an associated one of the adjacently disposed track sections thereby tensioning the endless chain as the threaded member is rotated.Type: GrantFiled: July 19, 1990Date of Patent: April 23, 1991Assignee: Gerber Garment Technology, Inc.Inventor: Richard Kuchta

Patent number: 4580338Abstract: To position an electrical insulator, having first and second ends at which are first and second sideways-projecting lugs, so that a part of the insulator lies on the upper face of a rail flange, another part of the insulator lies between the rail flange and a neighboring upward projection, and the upward projection lies partly between the lugs, the insulator is held in an inclined position by gripping its upper end between two clamping parts and moved with a component of motion parallel to the rail until the lower lug catches on the upward projection. Continued movement of the clamping parts cannot be followed by the insulator, which changes its orientation and prises the clamping parts apart. They release it and the higher end of the insulator descends, possibly as a consequence of force exerted on it by a clip. The clamping parts may be mounted on a magazine containing rail clips.Type: GrantFiled: June 9, 1983Date of Patent: April 8, 1986Assignee: Pandrol LimitedInventor: Peter Badger

Patent number: 4289274Abstract: A rail length and rail joint is described which avoids the use of bolts, the rail length comprising basically a fastening element secured at each rail end to be joined, the element being provided with a through bore extending parallel to the longitudinal axis of the associated rail length and a projection located in a position in which it intersects the bore and being radially displaceable to a location in which it lies clear of the bore. The rail length may be provided at each end with such a fastening element, one constituting a male element and the other a female element, the rail joint incorporating abutting male and female elements and a necked connecting pin.Type: GrantFiled: February 1, 1979Date of Patent: September 15, 1981Assignee: Gyro Mining Transport LimitedInventors: Richard C.
