  • La Point Assistant Examiner-Robert Saifer Attorney-Holman & Stern ABSTRACT A detachable gripping unit for the endless traction cable of amonocable aerial tramway in which a stationary jaw and two movable jaws are mounted in a common frame, with a hanger for a car being con- 3 Clains, 4 Drawing Figures DETACHABLE GRIPPING MEANS FOR MONOCABLE AERIAL TRAMWAYS BACKGROUND OF THE INVENTION ecuted, secured and checked by means requiring special appliances. It is essential that the gripping means can travel over all supporting sheaves or pulleys free from pushes and also pass the various hold-downsheaves or pulleys free from shocks in the line. Also, it is quite important to be able to ascertain the pressure of the closed grip at the time a car or gondola is left in the station.
  • the present invention is directed tov detachable gripping means for the traction cable of a monocable aerial tramway which comprises a frame, a stationary jaw in the frame, a hanger for a car secured to the stationary jaw, two independent jaws mounted in the frame in parallelism and movable toward and away from the stationary jaw to grip and release the cable respectively, independent spring means in the frame for each movable jaw urgingsaid movable jaws towards the stationary jaw, a lever operably related with each spring means, means pivotally connecting each lever to the frame, and a roller for each lever cooperable with a guide rail in a station to move each lever about its pivotal connection against the action of the spring means to move each movable jaw away from the stationary jaw to enable entry of the cable, the arrangement being such that if one movable jaw and its related spring means is rendered ineffective, the other movable jaw and its related spring means is effective to grip and release the cable, respectively.
  • the invention further includes means for testing or checking each gripping assemblage to detennine if the assemblage has the required pressure while the car leaves the station and to stop the main drive if the pressure is insufficient.
  • each gripping assemblage of an entering car to rest open in the station so that the same car can leave the station without the usual labor to release the clamp against the spring pressure.
  • FIG. 1 is a view partly in side elevation and partly in cross section of a detachable gripping assemblage embodying the present invention.
  • FIG. 2- is a plan view of the assemblage illustrated in FIG. 1.
  • FIG. 3 is an elevational view partly in cross section of means for testing or checking each gripping assemblage
  • FIG. 4 is a view partly in side elevation and partly in cross section of means enabling the opened gripping assemblage to be arrested and later closed with essential pressure labor.
  • the gripping assemblage includes a closed frame 2 which is equipped with two pairs of diammetrically opposed wheels 1 which are adapted to ride on tracks 15 into a station.
  • An endless traction cable or rope 4 is adapted to be gripped and released by a gripping mechanism denoted generally G.
  • the gripping mechanism G includes a fluid jaw or clamp 5 mounted in the frame 2 and two movable jaws or clamps 6which, when in the position illustrated in FIG. 1, coact with the stationary jaw 5 to grip the cable 4.
  • a hanger 3 for a chair, gondola or the like (not shown) is suitably secured to the stationary jaw 5.
  • spring means 9 is associated with each jaw 6.
  • the spring means 9 is guided by a rod 7 secured at one end to the jaw 6 with the opposite end passing through an aperturein the end of the frame 2 provided with a bearing 9.
  • the outer end of the rod 7 is provided with a U-shaped fitting 11 and a bolt 8 pivotally connects one end of a pilot'lever 10 to the fitting 11.
  • Each pilot lever 10 is pivotally connected to the frame 2 as indicated at 12.
  • the upper end of the lever 10 supports a roller 13 which travels along a guide rail 14 of channelsection located within a station.
  • a roller 23 is located at the lower part of the frame 2.
  • the testing or checking device includes a balance beam 18 provided with a spring 18' at one side of pivot point 18" and a pattern 17 on the other side of the pivot point.
  • the pattern 17 is adapted to pass through an elongated slit or slot 16 provided in the guide rail 14 and if the pressure of the spring means 9 is sufficient, the pattern 17 will be lifted by a passing roller 13 and the checked car can travel out of the station.
  • FIG. 4 there is illustrated means to prevent the opened grip assemblage to be reclosed during the drive in the station thereby resulting in substantial savings in labor for the following coupling sequence.
  • the problem involved is to block the spring pressure while uncoupling during the entrance of the car into aside the lever 21- by means of a spring 24 connected to the lever 21 and the frame 2.
  • I v j The invention further comprehends a double disposicable speed or carcapacity.
  • a detachable gripping assemblage for a monocable aerial tramway comprising a frame, a stationary jaw in the frame, a hanger for a car secured to the stationaryjaw, two independent jaws mounted in the frame in spaced apart parallel relationship, said independent jaws being opposite the stationary jaw'and movable tionof the gripping assemblage in each car for greater 'fective to grip andrelease the cable.
  • the gripping assemblage as claim in'claim l including means for testing the pressure of the jaws during the departure of each car from the station, such means including a balance beam pivotally mounted intemiediate the ends thereof, said balance beam includ-,
  • spring means biasing the beamvon one side of the pivotal mountingiand a pattern on the beam on the other side of the pivotal mounting passing through the, 2 guide rail operable to hold the roller of each lever in' turn away from the guide rail if the pressure of the spring means is insufficient and switching means for the main drive of the traction cable being actuated to arrest such drive when one of the rollers is in the tion.
  • the detachable gripping assemblage as claimed in latter posiclaim 1 including means for: arresting the movable jaws rectilinearly toward and away from thevstationary jawto grip and release the cable respectively, a rod secured at one end to each movable jaw and each other end passing through an aperture in the frame, a spring means surrounding each rod with one end bearing against each movable jaw and the other end against the frame for urging the movable jaws towards the stationary jaw, a lever pivotally connected to the other end of each rod, means pivotally connecting each lever to the in their position awayvfrom the stationary jaws includ-.
