Patent number: 5431424Abstract: A fifth wheel slip plate is described, in which plastic inserts are used in the plastic slip plate instead of metal skip plates, and in which a composite plastic material is used for outer lateral portions of the slip plate. The plastic of the insert, preferably nylon, is substantially harder than the plastic of the slip plate, which is preferably ultra high molecular weight polyethylene. The harder plastic insert therefore does not compress as much as the slip plate, and therefore absorbs the primary impact during the coupling operation. The composite material outer portions absorb much of the impact damage, without the undesirable friction which metal would produce, and they are relatively simple to replace, without need to replace the whole slip plate.Type: GrantFiled: April 7, 1994Date of Patent: July 11, 1995Inventor: J. Bruce Colwell

Patent number: 4752081Abstract: A low-friction plastic covering on the fifth wheel bearing plate of a tractor is protected from damage during tractor/trailer coupling by a pair of elongated metal "skip" plates. Such plates are preferably rectangular in shape and are positioned in the interior region of the plastic covering, one on each side of a tapered slot adapted to receive the kingpin of a trailer's fifth wheel tongue attachment. The size, shape and position of such skip plates minimize wear on the trailer's bolster plate, and minimize any tendency for tearing of the plastic covering during tractor/trailer coupling and normal use of the tractor-trailer. Preferably, the skip plates are welded to the tractor's fifth wheel bearing plate through counterbored slots in the plastic covering, whereby the skip plates additionally function as retainers for attaching the plastic covering to the underlying bearing plate.Type: GrantFiled: August 31, 1987Date of Patent: June 21, 1988Inventors: Donald G.
