Patent number: 8757510Abstract: The invention relates to a rail fastening on a tie having fastening screws and loop-shaped tension clamps in which the track width can be adjusted horizontally in a stepless manner using wedge elements, the rail being arranged on a ribbed plate, the ribs of which run at an angle to the rail and a wedge that can be moved in the longitudinal direction of the rail being arranged between rail foot and the ribs. The wedge is preferably guided on the support. This makes possible effective horizontal lateral displacement of the rail or modification of the track with the use of simple and inexpensive plastic parts.Type: GrantFiled: June 15, 2009Date of Patent: June 24, 2014Assignee: Wirthwein AGInventors: Udo Wirthwein, Joachim Süss

Patent number: 7922102Abstract: The invention relates to a rail support point for a rail-guided vehicle for anchoring in a wooden tie, including a plate as a support for the rail, which plate is anchored on both sides of the rail by means of fastening bolts that pass through the plate, the plate having on its bottom side collars that surround the fastening bolts and that engage in correspondingly shaped depressions in the wooden tie, the plate being configured as a ribbed plate having raised ribs that are arranged lateral to the rail foot and that guide the latter and being made of plastic, and the collar being embodied as a slitted ring. Also disclosed is a rail fastening using the rail support.Type: GrantFiled: June 10, 2009Date of Patent: April 12, 2011Assignee: Wirthwein AGInventors: Udo Wirthwein, Joachim Süss

Patent number: 7234647Abstract: The invention relates to a damping means for damping acoustic vibrations on rails. This damping means is, in particular, a body made of plastics and ferrous materials. The damping means is characterized by a chamber filling body, which consists of a thermoplastic and of metal constituents finely dispersed therein and is produced by extrusion or injection molding, whereby the density of the body is >2.4 g/cm3.Type: GrantFiled: April 7, 2003Date of Patent: June 26, 2007Assignee: Wirthwein AGInventors: Udo Wirthwein, Otto Kaulbersch, Dirk Vorderbrück

Publication number: 20050103062Abstract: A washing machine includes parts that are mounted in a manner that permits them to oscillate, particularly washing machine tubs, on which ballast bodies are fixed. The ballast body is approximately shaped like a ring or ring segment with a selectable cross-sectional thickness and comprises, on at least one circular are, a number of recesses and/or openings whose surfaces on points of contact are complementary to corresponding outer contours of fixing elements on the part. The ballast body is preferably made of plastic and ferrous material, which is shaped by injection molding a thermoplastic material, which contains significant proportions of filling material consisting of hematite and./or magnetite, in order to form a ballast body having a density >2.4 g/cm3.Type: ApplicationFiled: April 3, 2003Publication date: May 19, 2005Inventors: Udo Wirthwein, Otto Kaulbersch, Ute Kreuziger

Patent number: 6288331Abstract: A cable duct formed by cable troughs, an elevator cable duct and corresponding covers. The elevator cable duct has props and supports arranged thereon which extend in the longitudinal direction of the cable duct as well as plastic troughs which can be aligned next to each other, thereby forming a cable duct. The troughs have recesses on the outside which can be reversed-drawn above the support, where the troughs can be locked in positive fit or by frictional engagement. The recesses are deep enough to enable the support to lie inside the sleeve of the troughs when the troughs are mounted. The support is insulated from the outside by aprons. A longitudinally displaceable cover, which can be fixed to the trough, is located on top of the trough.Type: GrantFiled: July 14, 1999Date of Patent: September 11, 2001Assignee: Udo WirthweinInventors: Udo Wirthwein, Otto Kaulbersch, Jürgen Michel

Patent number: 5758821Abstract: A system for elastically fastening rails mounted on underlying cross ties. The foot of the rail is clamped by elastically fastening metallic rail spikes anchored in the cross tie. The rail spikes have a shaft portion and a head portion eccentrically arranged thereon, as well as a plastic element arranged in an electrically insulating manner. This fastening system also has a component linkable to the spike for impressing a permanent bending moment on the shaft portion in all stress phases and for permanently clamping the rail spike. This type of fastening system is suitable both for wooden and concrete cross ties. This system may also include a dowel to anchor the rail spike within the cross tie. This invention also impresses a permanent bending stress on the shaft of the rail foot, so that the rail spike extraction forces can be set at a higher level than is normally obtained.Type: GrantFiled: April 25, 1995Date of Patent: June 2, 1998Inventors: Udo Wirthwein, Wilfried Bonewitz

Patent number: 4907740Abstract: A device for attaching a rail to a bearing element (tie) (3) and comprising an elastic intermediate plate (34) and on top of this a rigid pressure distribution plate (35) which is arranged between the base (2) of the rail (1) and the tie (3); guide plates (10, 11) are attached to the tie (3) to provide lateral guidance of the base of the rail (2) and clamps (38) act on the base of the rail (2) and clamp the rail (1) to the tie (3). The elastic intermediate plate (34) projecting on both sides beneath the base (2) of the rail (1) extends on each side into a recess (16, 17) formed by the guide plate (10, 11). As a result, the elastic intermediate plate (34) can provide adequate resistance to the horizontal forces so that tilting of the rail is prevented. At the same time, the major forces of the clamps (38) are transmitted via the guide plates (10, 11) directly to the tie (3) so that non-uniform compression of the elastic intermediate plate (34) cannot occur during assembly and thus rail cant errors are avoided.Type: GrantFiled: June 20, 1988Date of Patent: March 13, 1990Assignee: Vossloh-Werke GmbHInventors: Gunter Oberweiler, Johann W. Spies, Udo Wirthwein, Friedhelm Weber
