Definitions

  • My invention has for its object a cableway provided with a sloping carrying rope for the transportation of tree trunks and the like.
  • the carrying rope of said cableway that is tensioned between 9. high point and a loading point on a road or a railway track carries a traveller that is designed in a manner such that a tree trunk or the like load may be raised through the traction cable of the cableway up to said traveller and, as soon as the load has reached its uppermost position, the traveller is set free and may be drawn upwardly through the same traction cable over the carrying rope or else it may be allowed to sink on the latter down to the loading station.
  • an automatic control in the traveller according to which the load is raised or transported towards the loading station, the automatic operation being controlled through the traction cable.
  • This allows a considerable reduction in the time involved and in the labor required.
  • a special positioning apparatus over the carrying rope into the desired position and said positioning apparatus has to be clamped to the carrying rope through the agency of a special retaining cable.
  • the present new cableway requires, on the contrary, no positioning apparatus and no auxiliary retaining cable and is consequently much simpler.
  • Fig. 1 illustrates the traveller in side view.
  • Fig. 2 is a cross section through said traveller carriage through line II--II of Fig. 1.
  • Fig. 3 is a side view of the traveller with its cradle in its tilted position.
  • Fig. 4 is a view of a modification of the centrifugal weight, forming part of the control means.
  • Fig. 5 is a cross section on enlarged scale taken on line V-V of Fig. 1.
  • the carrying rope I is secured at its lower end in the immedaite vicinity of the loading station in order to allow the transfer of the load onto a truck or onto a railway car.
  • the other end of the carrying rope is anchored in ground for instance on the mountain side in a manner such 1950, Serial No. 152,306 February 28, 1949 that said rope may be directed obliquely downwardly towards the loading station.
  • the carrying rope may advantageously be tensioned over a gorge or deep valley that is not within easy reach and out of which tree trunks for instance are removed and easily and rapidly transported to the loading station. It is also possible for instance to provide for the transportation of ore or the like mineral products from the mountains down to the point at which they are to be worked.
  • the traveller 2 is adapted to run along the carrying rope through the agency of its four wheels 3; these wheels 3 are preferably vertically adjustable so that it is possible to move them inv accordance with the curve assumed by the suspended rope and consequently to distribute uniformly the load over the four wheels.
  • These four wheels 3 are mounted inside a carrier member 4 made of sheet iron folded into the shape of a hook.
  • the two carrier members 4 and 5 are outwardly folded along their lower edges and open after the manner of a hopper at 33 on the side facing the loading station.
  • a cradle 1 is rockably secured between said carrier members 4 and 5.
  • Said cradle is constituted by two cradle plates 8 the upper edges of which are folded at right angles so as to form running surfaces for rollers 20 to be described hereinafter.
  • Carrier studs 9 are welded transversally to said cradle plates 8.
  • Said studs 9 are pivotally carried in the reinforcements l 6 welded to the carrier members or plates 4 and 5.
  • To the front free ends of the carrier studs 9 are secured through the agency of screws two sectors II to which may be adjustably secured centrifugal masses !2. These sectors l I form thus centrifugal masses and their object is to throw the cradle 1 from the position illustrated in Fig. 1 into the position illustrated in Fig. 3.
  • the cradle l is bent at this point in a manner such that it may easily move over said stops.
  • the cradle l is provided with a stop [3 at its free end projecting beyond the actual traveller.
  • the cradle is also provided at its other end with a pin l5 that is connected to the connecting rod I! which is pivotally secured to the brake lever I8 through an adjustable point of its length.
  • the brake lever I6 is pivotally secured to both carrier members 4 and 5 through the agency of the pin 18.
  • the brake shoe I9 is pivotally secured to the brake lever [B and its wedging action is adapted to clamp the traveller through said brake shoe to the carrying rope I for it to be held securely in the position considered.
  • the load carrier is associated with a support 2
  • the two rollers 20 are secured to either side of said support through the agency of a pivot.
  • is revolubly-carriedaroller 23 for the traction cable 24, adapted tde lide the; said traction cable.
  • To the catch 22 is pivotally secured a control rod 25 that is prov-idedat-its lower end with a control ring; 26'. reinforcedqbymeans of a semi-circular conical member 21; The; support '2!
  • the two carrier catches 2.3.- are connected through asspring that: is not illustrated andgthat urges the two catches 29 away fromone another-,- that: is, into-the rela: tive; positionillustrated-in Fig; 2.
  • thecarryingropel In the position illustrated in Fig. 1 for a traveller, thecarryingropel is braked and'inthis position, theload-"carrying means are held fast throughengagementblthe catch 22 with the stop 13 on-thecradle in a position-for which the TOHETSn-ZD- on said means are arrangedatthe outer-end of -thecradle-l
  • the traction cable 24 draws the whole load-carrying means together with the rollers 20 over the cradle 1 towards the inner position thereof inside the traveller.
  • the carrier catches 29 are urged towards one another at themoment the load carrying means enter inside the traveller, said inward movement of the catches 29 being controlled througl'rthe. lower parts 33 of the carrier members: 4 and15 that are bent into the shape of a hopper. The tips of the carrier catches 29 are thus urgedinto engagement with the underside of the. weight 30- that is thus held fast by said catches.
  • the winch may now draw upwardly the traveller throughthe traction cable 24 alongthe carrying-rope I together with the load or else it may allow the' traveller and load to-sink towards the loading" station.
  • the load carrier remainsin-its inner ter-- minal position insidethe traveller while the'brakei9-rernains in itsreleased position and the trac-- tion cable 2t may be drawn in again through' the winch and said cable may thus bring thetraveller along'the-ca-rrying rope I into exact vertical registerover the tree'trunk-that is to be transported.
  • the carrier catchers 29' are urged away from one another as byspring means, not shown; so as to release the weight 30.
  • the catch 22 snaps into position'behind the stop l3 on the cradle and holds the load carrying means fast in their outer terminal position with reference to the cradle 1, while the connecting rod l1 urges upwardly the brake lever l6 and therethrough also the cable braking -shoe l9,- whereby the traveller is clamped to the carrying rope I.
  • the load controlling-winch is now allowedito let the traction cable 24 move down- -.wardly with the carrier ring- 3
  • the operator of the load controlling winch may be called by telephone so that he may be told of the moments at which he is to allow the winch to unwind and at which he is to stop it or else communication is obtained with him through optic signals.
  • a marking provided on the traction cable allows the operator to be aware of the state of operation.
  • a ropeway executed in the manner disclosed is of advantage in service inasmuch as it allows a considerable economy in time, labor and expense and provides for the easy transportation of tree trunks out of gorges and isolated valleys, the access towhich is otherwise very difficult.
  • the service of this ropeway is a very simple one and the traveller is of a simple execution and operates in a very reliable manner.
  • a traveler for transportation of tree trunks and like loads over a sloping high-line comprising, in combination, a frame, means in said frame for travel over the high-line, a cradle pivotally mounted inside said frame to assume two tilted positions facing the lower and the upper nd of the sloping high-line respectively, an auxiliary carriage adapted to run over said cradle, a traction cable for hoisting the load and hauling the traveler, a hoisting block secured to the free end of said traction cable, means on said auxiliary carriage for guiding said traction cable, a brake structure to engage the high-line, lever means operatively connecting said brake structure with the cradle and adapted to provide operativeness and release of said brake structure respectively according to the tilted position assumed by the cradle, means for locking the carriage to the front end of the cradle facing the lower end of the high-line, means whereby the hoisting block when brought by the traction cable into proximity with the carriage releases said locking means, the continuation
