Definitions

  • a coupling device is attached to the end of an air or steam line of a railway vehicle for coupling the line to a corresponding line on a railway vehicle equipped with either a manually operated box coupler or an automatic central buffer coupler.
  • the device comprises a cylindrical coupler head with a tubular line connection being attached at an angle to one end thereof and the other end having a scalable opening for connection to a line opening.
  • a pair of diametrically opposed arms project radially outwardly from the coupler head with the ends of the arms having abutment surfaces which are engageable with openings in the wall surrounding an automatic central line couplet.
  • One arm has a stop for supporting a protection flap in its open position and the other arm has a downwardly extending extension which rests upon a edge of a wall opening to position the coupling device.
  • the device also has radial closure guides which are spaced and shaped to correspond with the closure guides on a manual line coupler and are positionable between the guide flanges partially surrounding a line opening on an automatic coupler.
  • the present invention relates to a coupler device for air lines on a railway vehicle, more particularly, to such a device which is adapted to connect a line to a railway vehicle equipped with either an automatic central buffer coupler or a manually operated box coupler.
  • the Austrian patent application A ll 334-67 discloses an arrangement for connecting the line of a railway vehicle provided with a hook coupler to a molded element that in turn is coupled to the automatic line coupler by means of a sleeve air coupler of conventional structure. According to this disclosure the railway vehicle then requires only a single shut off valve and hose line for each end of the vehicle and for each pipe line. If the vehicle is to be coupled to a vehicle having an automatic line coupler the pipe line can be connected by means of a shaped or molded element.
  • the line coupling is carried out after disconnecting the sleeve air coupler between the hose line and the shaped element by the connection of the sleeve air coupler of the hose line with that of the vehicle to be coupled.
  • every coupling operation may require several separate coupling steps depending upon the coupling equiptment of the vehicle being coupled.
  • the location of the shaped element introduces difficulties where the coupling must be carried out with a vehicle equipped with a sleeve air coupler since in such a situation the shaped element is free.
  • the present invention which essentially comprises a connector for coupling lines between railway vehicles.
  • the automatic line coupler is mounted in an air coupling passage and the line opening is at substantially the same level as the coupler.
  • the device comprises a substantially cylindrical coupler head having one end attached to an air line and its other end having an opening with means being disposed around said opening for sealingly connecting said opening to another line opening.
  • the body opening is substantially perpendicular to the axis of the coupler head.
  • First and second diametrically opposed arms project radially outwardly from the coupler head and the ends of the arms are engageable with wall openings in the coupling passage when the device is coupled thereto.
  • the ends of the arms engage surfaces adjacent the wall openings with these surfaces facing away from the coupling device.
  • the surfaces are at substantially Other objects and advantages of the present invention will be apparent upon reference to the accompanying description when taken in conjunction with the following drawings, which are exemplary, wherein;
  • FIG. 1 is a top plan view of the coupling device coupling a pipe line to an automatic line coupler according to the present invention.
  • FIG. 2 is a rear elevational view of the coupling device shown in FIG. 1.
  • a tubular hose connection 1 which leads from a pipe to be coupled (not illustrated in the drawings) is attached to a rear wall 3 of a cylindrical coupler head or body 2.
  • the connection 1 is inclined with respect to the longitudinal axis 4 of the coupler head 2.
  • a tubular coupling mouth piece 5 is slidably mounted on the other or front end of the coupler head 2 so as to be displaceable in the axial direction and projects outwardly from the head 2.
  • a sealing ring 6 is carried within the mouth piece 5 and is sealingly engageable with a line opening of an automatic central line coupler. The sealing ring 6 surrounds this line opening.
  • the cylindrical coupler head 2 has mounted thereon diametrically opposed radially projecting arms 7 and 8 which extend laterally as may be seen in FIG. 2.
  • the arm 7 is provided with a shoulder 9 at its outer end and on the central portion of arm 7 on the side turned toward the opening there is a projecting stop 10 having an outwardly disposed lateral surface 1 l.
  • the arm 8 is bent obliquely in the forward direction with respect to the coupler head 2 and is provided with a shoulder at its outer end which forms an abutment surface 12 which is substantially parallel to the longitudinal axis 4 of the coupler head 2. Adjacent to the abutment surface 12 the arm 8 is provided with a rearwardly directed abutment surface 13 which extends to the extreme end of the arm and is disposed obliquely in the forward-outward direction with respect to the line opening on coupler head 2.
  • the front face of arm 8 adjacent the outer end thereof is provided with a surface 14 which is inclined obliquely rearwardly and outwardly again with respect to the line opening on coupler head 2.
  • the coupler head 2 is also provided with diametrically opposed radial closure guides 15 and 16 which are positioned forwardly of the arms 7 and 8 in a direction toward the opening of coupler head 2 and also project radially in the forward direction.
  • the radial closure guides correspond to the radial closure guides of a manually operated coupler both with respect to their structure and their position.
  • An automatic central buffer coupling having an automatic central line coupler is illustrated in dot-dash lines with only those components being shown which are necessary for the description of the structure and operation of the coupling device disclosed therein.
  • the automatic line coupler is provided with a coupling pipe 17 whose line opening is connected tightly to the tubular element 5 of coupler head 2 by the sealing ring 6.
  • Adjacent and partially surrounding line opening of line 17 are guide flanges 18 which project outwardly beyond the line opening and are constructed and arranged in the conventional manner.
  • the radial closure guides 15 and 16 grip between the guide flanges 18.
  • the coupler head 2 is centered with respect to the automatic line coupler by a suitable shaping of the edge zones of the closure guides 15 and 16.
  • the automatic central line coupler is positioned in an air coupler duct 19 of the central buffer coupling.
  • the flap 22 is spring biased into the closed position to cover the line opening of pipe 17.
  • the outer end of arm 7 extends into wall opening 2
  • the shoulder 9 is positioned a distance s from the wall 20.
  • the protection flap 22 is shown in its pivoted-out position which it occupies when the device is coupled to the automatic line coupler. 1n the out position the edge of the flap 22 is supported on the lateral surface 11 of abutment 10 on the arm 7.
  • the flap 22 holds the coupler head 2 in a position which is determined by the abutment of surface 12 on the arm 8 on a lateral boundary surface 24 of an opening 25 in a side wall 26 which defines the air coupling duct or passage 19 on the other side.
  • the outer end of arm 8 extends beyond the side wall 26 and its abutment surface 13 rests upon a surface 27 adjacent the opening 25.
  • the coupler head 2 is shifted laterally toward the side wall 20.
  • the protection flap 22 will also be shifted laterally under the action of the stop 10 moving against the spring force of the flap until the shoulder 9 abuts the outer surface of the side wall 20.
  • the arm 8 can be disengaged from the wall opening 25 and moved outwardly past side wall 24 in a direction toward the left as viewed in FIG. 1.
  • the entire connector line coupling device can then be removed from the automatic line coupler or from the central buffer coupling.
  • the coupling device in the coupling operation, is moved toward the automatic line coupler at an angle from the side of the side wall 26.
  • the stop 10 will engage the edge of the protection flap 22 and will move this flap away to uncover the line opening of coupling pipe 17.
  • the outer end of arm 7 is then inserted into the wall opening 21 and the arm 8 with its forward surface 14 is pressed against the side wall 26. Because of the oblique arrangement of the surface 14 the coupling device will be shifted in the direction toward side wall 20 until the outer end of arm 8 can pass beyond the boundary surface 24 and enter into the wall opening 25. After slightly shifting the coupling device toward side wall 26 under the force of the spring acting upon flap 22 the coupling device assumes the position illustrated in FIG. 1.
  • the arm 8 may be provided with a vertically downwardly projecting extension 28 positioned close to and in front of the abutment surface 12.
  • the extension 28 will rest on a lower edge 29 of the opening 25 when the coupler device is coupled to an automatic central line coupler as shown in the drawings.
  • the coupler head 2 with its sealing ring 6 is pressed on the line opening of the air coupler and subsequently pivoted so that the radial closure guides and 16 will lockingly engage the corresponding closure guides on the air coupler.
  • the coupling operation is carried out in the same manner as in the case of two ordinary or conventional sleeve or manually operated air couplers.
  • Two coupler heads 2 of two connector line couplings can also be equipped together by means of the closure guides 15 and 16.
  • the closure guides 16 of the two coupler heads function in the same manner as the closure guides of two sleeve air couplers and are mutually interconnected.
  • the automatic central line coupler may also be provided with structure for coupling two additional lines. This is customary for automatic central line couplers and central buffer couplings are presently employed.
  • the coupling lines in the automatic line coupler are positioned vertically above each other.
  • the coupler head 2 as described above is particularly suited for coupling to the line 17 which is positioned at the central level of an automatic line coupler. However, if the coupler head 2 is to be coupled to a line 31 positioned below the central line it may be necessary to modify the position of the closure guide 16.
  • One such modification may comprise mounting the closure guide 16 rigidly to arm 8 in a position displaced with respect to the arm 8 by approximately 118 degrees and to support the closure guide 16 and arm 8 jointly on the coupler head 2 so that both elements are pivotable about the longitudinal axis 4.
  • the closure guide 16 can be then rotated into a position covering closure guide 15 in which it does not obstruct any coupling operation with respect to an automatic line coupler.
  • the arm 8 will project from coupler head 2 diametrically with respect to the arm '1.
  • the closure guide 16 will be pivoted back to its original position and the arm 8 will then be rotated about the axis 4 toward the arm 7.
  • This has the advantage that when coupled the arms 7 and 8 will project from coupler head 2 only in an approximately single direction so that the prescribed relationships can be readily observed because of the small requirement of space of the coupler device when it is coupled. This is particularly true with respect for the ground clearance of the vehicle which is not decreased since in this arrangement the coupling devices no longer have an arm or extension projecting vertically downwardly.
  • the present invention has disclosed a coupling device for connecting lines to a railway vehicle equipped with either of different line couplers.
  • the coupler device may also be connected to a similar coupling device.
  • the present coupler device has only a minimum number of parts which must be positioned together to complete a coupling operation. All of the components necessary for the coupling operation are carried by the coupling device and it is not necessary to store or to insert any additional elements when the coupler device is to be coupler. Further, no additional coupling operations must be performed during or prior to the actual coupling procedure.
  • the construction of the coupling device including the angular connection of a line to the coupling device provides for an automatic uncoupling should excessive tension forces be exerted on coupled lines in the event the railway vehicles should become uncoupled.
  • the present invention also provides for coupling two or more lines to a railway vehicle equipped with an automatic line coupler having a plurality of lines or to a conventional manually operated air coupler.
  • said abutment surface extending obliquely outwardly and forwardly with respect to said opening.
