Line funding with combined wire rope.

Patented in the German Empire on December 14, 1880.

The system of mechanical line conveying represented by the accompanying drawings has for the purpose:

1. Machine conveyance in sections of multiple curved and broken shape and moderate increase respectively. I also like to alternate between horizontal and ascending ones and to facilitate falling parts of the route,

2. Safe, automatic switching on and off of individual wagons at any point.

On the drawings is:

Fig. Ι a horizontal section through any broken route with various branches of the tracks,

Fig. 2 shows the length profile of the same route,

3 and 4 the detail of a trolley,

5 shows the profile of the combined hoisting rope to be used,

6 and 7 side and front view of the fork of the trolley,

Figs. 8 and 9: Basic outline and longitudinal section of part of the routes.

The whole arrangement is based on the fact that not one rope is led through the entire length of the conveyor, but as many endless ropes are used as there are corners or bends in the route. In doing so, of course, smaller curvatures, etc., are regulated by re-cutting. At each turn there is a vertical shaft A, Fig. 1 and 2, 8 and 9, which usually carries two pulleys ί S _1. The first of these waves A ₁ is set in motion (preferably also by cable transmission) from the machine M, FIG. 1. The endless rope for the next conveyor section lies on the second pulley S _{1 of} this shaft and at the same time transfers the movement to the pulley s of the shaft A ₁₁ , on whose second pulley S ₁ the rope for the second section is again, etc. The guide of the rope is indicated on Fig. 1 and 2 by a dash-dotted line (- · · - · · -). If the conveyor line forks or if one or more conveyor lines operated in the same way with mechanical conveyance branch off, as many sheaves are to be attached to the respective shaft at the fork, intersection or deviation point as there are individual sections of the line. So are z. B. at A ± three sheaves are necessary.

The railway tracks are placed so, that in each of the two tracks a few meters before the corner, or bend a highest point mm _n Fig. 2, place, from which the trolley voluntarily descending, passed the curvature. To the end is the position. of the sheaves and the guiding of the rope such that it releases the carriage at points m Tn ₁ and catches the carriage again at points η n _t , where the train reaches the normal level again and transports it on in a horizontal or slightly inclined route up to the next height point m. This guidance of the rope is clearly shown in FIGS. 8 and 9 and will be explained in more detail below. The rope itself is made up of three weak, easily flexible ropes,

Claims (1)

which three ropes together have sufficient strength for all possible loads own. At distances from 0, _S om to ι m, these three ropes, as can be seen in FIGS. 5, 8 and 9, are connected by clamps or brackets cc made of flat iron. The latter protrude on both sides by about 30 mm over the ropes and thus form a point of application that grips the fork g attached to the trolley, FIGS. 3 and 4, into which the rope is easily inserted. This fork has the shape shown in FIGS. 6 and 7. If the carriage running off the inclined plane has a greater speed in the conveying direction indicated by the arrow than the rope, a damaging substance could arise when it is caught by a clamp c of the conveying rope. The shape of the fork, which is bevelled from p to q, has the effect, since with the slightly inclined position of the hoisting rope, only the top end of the fork comes into contact with a clamp, in this case the rope dodges upwards while the carriage moves at the same time is delayed appropriately. Once the correct ratio has been achieved, a bracket grips firmly at 0 and cannot be torn loose even by small vibrations of the rope. The pressure rollers RR ₁ and the guide rollers aa _t and bb _r are used to keep the rope in such a position that it automatically grabs the carriages in the right way and releases it and regularly wraps itself around the pulley ί S ₁ simple, ordinary pulleys are set up and have only one cable groove and a small width, so that each such pressure pulley only holds the middle of the three combined cables and allows the fork of the trolley to pass freely and without contact. The guide rollers α a _f and b O ₁ are set up similarly to those customary in other cable cars and are provided with triple grooves, corresponding to the three combined ropes. The pressure rollers RR ₁ and guide rollers ί S ₁ are either made entirely of wood or, if they are made of iron, to be lined with wood or similar materials that do not attack the ropes. The pulleys s S _{1 also} receive on their circumference depressions dd, in which the brackets cc lay, whereby the rope held on the pulley or. is taken by the same. For greater performance and for safety, teeth can also be attached to the pulley, which the brackets cc attack. It is therefore necessary that the distance between the brackets cc be an aliquot part of the circumference of the pulley. If there is a noticeable lengthening of the rope or if the sheave is worn, the latter must be enlarged by nailing wood or leather. All these rolls and disks are stored in lumbered lines in the carpentry; In undeveloped or masonry stretches, wooden lines or iron fasteners must be attached. If the shafts AA are far from each other in any stretch which is straight for a longer length and the carriages follow each other in somewhat larger spaces, then both pressure rollers R at the corresponding height and guide rollers in the bottom of the route are switched on. The operation of the promotion is then as follows: The trolley coming from a side stretch or from the conveyor pan is pushed into the relevant route at a speed corresponding to the speed of the rope so that it can be grasped by the clamps of the rope, which operation is facilitated by a suitable gradient of the tracks. The rope now takes it with it up to the elevation point m or m _f before the next turn, where it slides out of the fork due to the action of the guide rollers b or b _t. In the meantime the wagon has reached the inclined plane m η or m _t U ₁ , which it runs down freely and is then gripped by some clamp of the next rope section and transported on again. The activation and release of the car must therefore either take place at a point at which the route has a bend, thus also a cable shaft AA ₁ with the entire pressure roller and guide roller apparatus, then the inclined planes etc., is present, or else, if you want to make a turn in the straight stretch, the necessary equipment must be attached with the omission of the cable shaft A. Patenτ claim: The arrangement of the individual, the straight track pieces respective endless ropes made of three adjacent, in gleichmäfsigen distances with the associated in Fig. Parentheses shown 5 wire ropes which extend to the corners and bends of the conveyor path to horizontal, dd with the recesses Fig. 9, and gear sheaves provided with teeth and thus, in addition to their function as conveyor ropes, also effect the transmission of motion from one sheave shaft to the other.
