Definitions

  • ABSTRACT A deflector for a cable transport system, wherein the cable is provided with a plurality of members each supporting a load, has a wheel rotatable about an upright axis and provided around its periphery with a plurality of ang ularly equispaced guides. Each such A guide is carried on one end of a short arm pivoted itself on the periphery of the wheel so that the guides can be pushed to the side by the load-carrying members as they pass.
  • the guides are :small synthetic-resin sheaves which are rotatable about respective axes on their respective arms.
  • the arms normally project radially inwardly of the wheel.
  • a cam is provided to array those guides in contact with the cable along the desired arc.
  • a plurality of pairs of notched jaws are provided which are opened by a cam as the cable comes between them and are then closed on this cable. In case an outrigger comes between these jaws they merely close on it. The jaws are opened again to permit the cable to leave the deflecting wheel.
  • Such an arrangement is quite complicated and liable to fail under heavy load.
  • the mechanism which opens and closes the jaws must be protected from the elements, necessitating a closed housing around each deflection tower.
  • each guide is a small synthetic-resin pulley or sheave rotatable on the other end of its respective arm about an axis parallel to the pivot axis for the one end of the arm,
  • each arm is provided with a projection engaging over a formation on the wheel so that the vertical and torsional forces applied to the arm are not all taken up by the pivot.
  • This projection can rest on an arcuate lip having a center of curvature coinciding with the arms pivot axis.
  • means is provided to displace the pivot axes of the arms so that in the region they engage the cablethey lie in an upright warped plane parallel to the curve that the cable is supposed to follow. This is accomplished by providing the pivot axes in eccentric bushings which are engaged by a relatively fixed cam so that these axis lie in a plane having the desired radius of curvature.
  • FIG. 1 is a top diagrammatic view of a system according to the present invention
  • FIG. IA is a view of the portion cated by arrow IA of FIG. 1;
  • FIG. 2 is a bottom view, in enlarged scale, of that porof the system indition of the system indicated by arrow II of FIG. 1;
  • FIG. 3 is a section taken along line III-Ill of FIG/2;
  • a cable transport system has a drive sheave 1 powered by a motor 21, an idler sheave 2 and a deflecting tower 3 :from which are suspended two wheels 4 and 4.
  • the latter wheel is a simple circumferentially grooved sheave and the former is described below.
  • Both wheels 4 and 4' are hung on shafts 9 from universal joints 22 and 22', respectively, which are spring loaded and allow limited rocking of these wheels.
  • a cable 7 is spanned over the wheels 1, 2, 4 and 4' and is provided with a plurality of laterally projecting outriggers 8 each suspending a respective load 23, here a two-man ski-lift chair.
  • the wheel 4 is on the inside of the bend in the path of the cable 7 and to that side of the cable 7 from which the outriggers 8 project.
  • the wheel 4 is generally circular and rotates about an upright axis A.
  • the periphery of this wheel 4 is provided with forty-eight angularly equispaced cable guides 6 in the form of small hyperboloidal sheaves made of a polyam'ide such as Nylon.
  • Each such guide 6 is rotatable about an axis A" defined by a pivotbolt 12 extending down from one end of a short arm whose other end is provided with an upwardly extending pivot bolt 11 defining an axis A.
  • the axes A, A and A" are parallel so that the arms 10 swing in planes orthogonal to these axes.
  • the bolt 11 is received in an elastic bushing in a hole 24 in the wheels periphery 5.
  • each arm 10 is formed with a short projecting tongue 13 which engages over a respective arcuate lip 14 formed on the wheel 4 inside of its outer periphery.
  • Each lip has a center of curvature at the respective axis A and a constant radius of curvature so that the tongue 13 engages over it and supports the arm 10 so long as this arm is directed generally inwardly.
  • the cable 7 is received in the peripheral groove of the sheave 6 and exerts, as shown in FIG.
  • a spring as shown schematically in FIGS. 3 and 4 at 28 is provided at each arm 10 to urge this arm into a position normally extending radially inwardly from the axis A.
  • FIG. 2 shows how as the cable 7 is displaced in the direction indicated by arrows D an outrigger comes into contact with a guide 6 and pushes it axially to the side. This allows the cable to seat itself securely on the guides 6 to either side of the outrigger 8 for most even application of force on the tower 3. As the outrigger leaves the arc of contact of the cable 7 with the wheel 4, it merelypulls out from between the guides, which then are returned to their radial positions by the springs 28. A cam 16 which is fixed on the shaft 9 and is not rotatable with the wheel 4 insures that these guides 6 are in this radial position as they come against the cable 7.
  • FIG. 6 shows an arrangement wherein the same reference numerals as used in FIGS. 1-5 are employed where structure is identical.
  • a plurality towers 3 are employed to deflect the cables 7 through bends having radii 17 of curvature which are much greater than the radii 18 of the respective deflecting wheels 4' shown in FIGS. 7 and 8.
  • each pin 11 is pivoted in an eccentric hole 29 in a bushing 19 which is rotatable within an enlarged hole 24' in the periphery 5 of the wheel 4.
  • Each such bolt 11 carries a metal collar which in the region of contact of the guides 6 with the cable 7 is engageable with a nonrotatable guide cam 21 whose edge has the same radius of curvature as the radius 17. In this manner the pins 11 are pulled toward the axis A so that the collars 20, which are advantageously rotatable on the pins by means of bearings, ride along the edge of the cam 21.
  • a wheel having a periphery and mounted on said support for rotation about said axis;
  • respective arms each having one end secured to a respective pivot and another end spaced from said respective pivot, said arms being swingable about said pivots;
  • each arm is provided with a projection and said wheel is formed with respective outwardly directed recesses receiving said projections.
  • each recess is circularly arcuate and has a center of curvature at the respective pivot axis, each projection overlying the respective recess.
  • deflector defined in claim 3, further comprising means for displacing said pivot axes on said wheel along a portion'of the periphery thereof to lie along an are having a center of curvature offset from the wheel axis.
  • said means for displacing includes a cam nonrotatable relative to said wheel and extending along said portion of said periphery, said cam being operatively engageable with said upwardly extending pivot pins of said arms.
  • said means for displacing further comprises respective bushings rotatable in said wheel and having an offset hole rotatably receiving a respective upwardly extending pin of a respective arm, whereby rotation of said bushings displaces the respective pivot axes relative to said upright axis.
  • each uping means for arraying said arms normally into a posiwardly directed pivot pin is provided with a guide collar tion extending radially inwardly from their respective engageable with said cam. V pivot axes.
