Definitions

  • the invention relates to cable-drawn wagons on funicuing device, which bottom is held in raised position as long as pressure is exerted on the cable, but in case of breakage of cable is lowered by automatic engagement of the braking device.
  • the purpose of the invention is to provide a braking device for such a wagon which is simple, strong, effective and reliable in operation.
  • the device according to the invention consists essentially of a vertical housing fitted to the lower side of the bottom, and a rail clamp suspended in the housing.
  • the bolt is at its ends passed through vertical slots in the housing wall, in such manner that a limited relative movement is made possible between the housing and the rail clamp.
  • the rail clamp is provided with means which by the lowering of the housing and the rail clamp will rest against the rail top and stop the descending movement of the clamp, in such manner that the jaws of the clamp, by the continued descent of the lower edges of the housing, will be firmly clamped to the rail head.
  • the housing is provided with a bolt located between the clamp jaws which, by the raising of the housing, will cause the jaws to fall apart before they are raised by the continued lifting of the housing.
  • the said means may, for example, take the form of knobs or shoulders, turned inwards, on the clamp jaws, located at a suitable height above the lower ends of the jaws.
  • the means consist of plate-shaped members which are journalled above on the upper edge which car ries the clamp jaws, in such manner that the plates are located between these and the inner wall of the housing.
  • Fig. 1 is a vertical projection of the braking device according to the invention in raised, inactive position over a rail shown in section.
  • Fig. 2 shows in a similar way the device in braking position, partly in section, and
  • Fig. 3 is a side elevation, forming part of Fig. 2, with the housing partly cut away and partly in section.
  • Fig. 4 is a side elevation view of one end of a conventional cable-drawn car with the platform in the lowered position and with a braking device according to the present invention mounted thereon;
  • Fig. 5 is an end elevation view of the cable-drawn car of Fig. 4.
  • Figs. l-3 1 denotes a housing which is fastened at its upper end to the lower side of the raisable and lowerable bottom of the car, as seen in Figs. 4 and 5.
  • 2 denotes two clamp jaws which at their upper ends are pivotably journalled on a horizontal bolt 3, which is vertically journalled in longitudinal excisions 5 on opposite walls of the housing 1.
  • the housing 1 is mounted on the under side of a frame 18 of a cable-drawn car, being braced in position by brace 19.
  • the car which is conventional, is supported on wheels 10 which are rotatably mounted in supportmembers 11.1
  • the support members are rotatably mounted on the under side of frame 18 by pivots 13 so that on rotation of the support members 11, the frame 18 is raised or lowered relative to the wheels 10.
  • Rigidly secured to the support members 11 are arms 14 which have pivoted to their free ends 15 cable anchors 16 which in turn have cables 17 attached thereto. When tension is exerted on the cables 17, either to pull the car up an inclined rail or to restrain its descent along the rail, the arms 14 exert a rotational force on the support members 11 and cause the car frame 18 to be raised.
  • each car will be fitted with two or more braking devices, suitably two, which will act on its rail.
  • a braking device for cable-drawn vehicles with a raisable and lowerable platform thereon comprising a housing extending in the direction of raising and lowering said platform and raisable and lowerable with the platform, a pair of plates slidably mounted in said housing, stop means on said housing engageable with said plates for limiting the sliding movement of said plates in said housing, said plates extending beyond'the end of said housing away from said platform when at one extreme of sliding movement, and a pair of rail clamping jaws pivotally mounted on said plates for movement around an axis perpendicular to the direction of raising and lowering, said rail clamping jaws extending out of said housing and having rail clamping heads thereon.
