Definitions

  • This invention relates to electric cable couplers for railway vehicles. Arrangements whereby such couplers are connected with railway draft couplers are well-known,
  • the electric cable coupler is so applied to the draft coupler that when the latter is disengaged from a mating coupler said cable coupler is maintained in a fixed relation to said draft coupler whereby the correct contacting of two cable couplings during engagement of the corresponding draft couplings is insured, said cable couplers, when coupling has been effected, being movable as a unit within sufficient limits with respect to the connected draft couplings so that displacements of the latter relative to each other during a trip do not impair the connection of the electric cable couplers.
  • Fig. 1 is a horizontal section through a head of an electric cable coupling, showing also the head of a draft coupling arranged beneath said cable coupling.
  • Fig. 2 is a vertical longitudinal section through the lateral guides of two engaged electric cable couplers.
  • Fig. 3 is a front elevation of a coupler headof the electric cable coupler
  • Fig. 4 is a front elevation of a coupler head showing a modified form of the invention.
  • a draft coupler heads which in the embodiment here disclosed are of the well known central bufier type.
  • Into these guide sleeves project correspondingly shaped projections or lugs 0 of the coupling heads (Z of the electric cable coupling. These projections are tapered forwardly in the same sense as the guide sleeves Z).
  • the backward end surfaces of the projections 0 are so formed that they permit a pivotal movement of the projections viz. a tilting about an imaginary horizontal axis lying in the plane of these end surfaces together with a simultaneous rectilinear longitudinal displacement in. the guide sleeves I) provided that the couplings a are in coupling engagement; and accordingly the projections 0 are pushed back out of the reduced or tapered part of the guide sleeves b by means of the contacting of the annular surfaces of the cable coupling heads (Z, the springs c acting upon the cable coupling heads (Z being compressed by this movement.
  • the resiliently slidable contact pins f are arranged in the insulation 2' of the coupling heads (Z.
  • the upper and lower edges of the front surface of the cable coupling are provided with projecting ribs h.
  • the contacts are under the influence of springs 70.
  • the sum of the forces exerted by the springs is smaller than the force of the spring 0 so that the coupling heads (Z are not separated by the force of the springs 70.
  • a draft coupler an electric cable coupler, means for projecting said cable coupler forwardly with respect to said draft coupler, and cooperating means on said couplers for guiding said cable coupler to projected position and providing for relative angular displacement between said cable coupler and said draft coupler when the latter is engaged with an opposing coupler.
  • a draft coupler an electric cable coupler, cooperating means between said couplers for holding the cable coupler in a definite relation to the draft coupler when the latter is disengaged from an opposing coupler, and means on said couplers for maintaining the cable coupler operatively united to an opposing cable coupler but angularly shiftable with respect to the draft coupler when the latter is engaged with an opposing draft coupler.
  • a draft coupler In combination, a draft coupler, an electric cable coupler, and means comprising interengaging )rojections on said draft and cable couplers or holding said cable coupler in a given position on said draft coupler, and responsive to engagement of said couplers with opposing draft and cable couplers respectively for providing for angular displacement of the cable couplers with respect to the draft couplers.
  • a draft coupler and an electric cable coupler means whereby the cable coupler is held in fixed relation to said draft coupler when the latter is disengaged form an opposing coupler, and means whereby said cable coupler is freed for pivotal movement with respect to said draft coupler when the latter is engaged with an opposing coupler.
  • a draft coupler In combination, a draft coupler, an electric cable coupler, cooperating projecttions on said couplers respectively, said projections having portions precluding pivotal movement of the cable coupler with respect to the draft coupler and other ortions providing bearings for tilting of the, cable coupler with respect to the draft coupler when the first mentioned portions are out of action.
  • a draft coupler an electric cable coupler, one of said couplers having a projection of truncated formation, a sleeve element on the other coupling having a truncated portion adapted to receive said projection for preventing rotation of the electric cable coupling, said sleeve element having a portion thereof providing for pivotal movement of said cable coupler when the latter is displaced longitudinally of said draft coupler.
  • a draft coupling an electric cable coupling, a projection of trancated formation on one of said couplings, a sleeve member having a truncated inner portion adapted to receive said projection, said sleeve member being on the other of said couplings and having a portion cooperating with said projection to provide for pivotal movements of the electric cable coupler when the latter is displaced longitudinally of the draft coupling, the periphery of said projection cooperating with said sleeve member to completely close the latter.
  • a draft coupler an electric cable coupler, and means precluding pivotal movement of said cable coupler with respect to said draft coupler when the latter is disengaged from an opposing coupler but permitting relative longitudinal movement between said cable coupler and said draft coupler, said means providing for relative pivotal movement between said cable coupler and said draft coupler in response to relative longitudinal movement therebetween.
  • a draft coupler comprising a sleeve member and a projection cooperating therewith for maintaining the cable coupler in a given position on the draft coupler and for providing for angular displacement of the cable coupler with respect to the draft coupler when the latter is engaged with an opposing coupler.
