The arrangements hitherto employed for.

dumping slag or other materials which are dumped into mounds by means of a cable way consisted essentially in the cables for carrying the cars being drawn across the place where the respective material was to be dumped, so that such material could be dumped up to a given height, determined by the position of the cables, by the cars running on these cables being automatically emptied. In consequence of the very high and therefore very expensive tower structures which would be required for large dump-mounds, which may sometimes run up to several hundred meters in helght, this method cannot be used for large dump-mounds, and dumping bridges have: Thls latter artherefore been employed. rangement conslsts of a bridge secured 1n an inclmed position to the tower, this br1dge having an overhanging end, on which the rail-track for the suspension cars is provided. By discharging the cars at the overhanging end a mound may be dumped up to the maximum height possible; the bridge is then lengthened by a short piece, and the mound is dumped still higher. By repeatedly extending the bridge the size of the dump-mound may be increased to any height. It. is, however, obvious, that such a bridge will require a very large and costly structure.

The present invention refers to an arrangement, which will allow of dumping slags to any height, without any costly and extensive structures and bridges being required; this purpose is obtained by employing cables as tracks for the cableway-cars, the position of said cable-tracks being adjustable according to the increasing height of the mound, a comparatively small tower being used for supporting such cable, which tower is arranged to travel on the already dumped material and preferably moves on tracks by means of wheels.

In the accompanying drawing Figure 1 is a total view of a cableway fitted with this arrangement, while Figs. 2-6 show various constructional forms of the traveling structure in elevatlon and plan. Figs. 7 and 8 show a constructional form of the mechanism serving to move the traveling structure.

The cables a are anchored at b in known manner, as shown in Fig. 1, and held taut by tension-weights at c.

The essential feature of the new arrangement is the structure (Z serving to support T the cables a along the side of the mound and which is arranged to travel either on a stationary structure 6 (Fig. 1) or on a mound f, which may have been previously dumped in any manner. are supported on structure d in known manner by runners 9 may be either directed to the center of the structure, as shown in Fig. 3 in plan view, or carried on without de- The cables a which flection over the runners g, as shown in Figs. i

4: and 5. With the former arrangement the cableway-cars h (Fig. 2) are transferred from the one cable a to the rails 2' and conducted in known manner by means of the sheave] serving to guide the hauling rope l 70 and the cars, to the other cable a and then down again to their point of starting.

In the arrangement shown in Figs. 5 and 6 the suspension cars it run over the structure (Z and down the other side of the mound and are here transferred in a reversing station arranged in known manner at Z), to the other cable a, and then conveyed back again to their point of starting. The arrangement according to Figs. 4 and 5 may also be employed on single cableways, in which the cable serves both for supporting the cars and as hauling rope. In such instance a number of rolls arranged behind each other will have to be provided in place of the runners for supporting the cables.

The traveling structure d is provided with an extension at its front end, projecting beyond the front wheels or the edge of the V mound, at the end of which extension the cars are automatically discharged. For the purpose of supporting the structure rails we may be provided, which are suitably laid on wooden cross-pieces or the like and may also be supported by specially provided sleepers.

The structure 61 may be secured in any suitable manner on rails m, say by blocks 0 screwed to the rails and bearing against the wheels.

For preventing the rails m or their sleepers n from slipping down, a bracket-like contrivance 7), preferably made of wood may be provided at their upper ends, which are therefore made to project beyond the summit of the mound f, this contrivance resting against the opposite slope of the mound and being afterward left covered up in the latter.

The operation in dumping the mound is the following. In its initial position the structure d rests against a mound f previously dumped by suitable means, or if there is no such mound available, on a special structure or brick-pier e erected for the purpose. After the material has been dumped up to the height shown by dotted lines in Figs. 2, 4 and 6, the track m is ex-- tended, and the structure (Z is moved on to the freshly dumped mound, whereupon dumping may be continued. By repeating these operations several times, the mound may be increased to any degree. To lengthen the track, a plurality of sections of rails m and the sleepers n may be used, which are free at the lower end of the track at the rear of structure (Z. If, after a given height has been reached it should appear desirable to extend the mound in a horizontal direction, it will be only necessary to modify the front end of the structure (Z, as shown in Fig. 6, for which purpose provision may be made in constructing the structure (Z. The cables at will then have to be supported in the manner usual in cableways at the point where the inclined direction passes into a horizontal direction. The arrangement may also be employed, when an existing mound of a certain height is to be extended in a horizontal direction.

For advancing the structure (Z any suitable contrivance may be employed, such as pulley-tackle, rack and pinion gear or the like. A suitable arrangementis shown in Figs. 7 and 8. On the structure (Z are fitted one or several chainor cable drums g, the chains or cables 1* of which are secured to a cross-beam s fitted between the rails m or their sleepers a. If the drum 9* is turned by means of crank handles or motor power the cables or chains 1' are wound around the drums 9, whereby the structure will be advanced. If the structure (Z is provided ac cording to Figs. 2 and 3 with a sheave Z for the hauling rope 7c, the structure (Z may also be advanced by the mechanical means serving this purpose being actuated by the sheave Z rotated by the hauling cable 7:, the said sheave being coupled by suitable means in a disengageable manner to the other me chanical parts.

I claim:

1. Mechanism for forming a spoil heap, mound or bank, comprising in combination, cables extending across the point on which the mound is to be formed, movable structure on the side of said mound adjacent the summit thereof for supporting the cables, a set of rails for said structure, means securing said structure to said rails, and a downwardly extending bracket for said structure, substantially as described.

2. Mechanism for forming a spoil heap, mound or bank, comprising in combination, cables extending across the point on which the mound is to be formed, a movable structure resting alongside the mound adjacent the summit thereof for supporting the cables, a set of rails for said structure, means to secure the rails to said structure, and a downwardly extending bracket for said structure embracing the summit and extending downwardly with respect thereto on that side opposite the side on which said structure is disposed, substantially as described.

3. Mechanism for forming a spoil heap, mound or bank, comprising in combination, cables extending across the point on which the mound is to be formed, a movable structure on the side of said mound adjacent the summit thereof for supporting the cables, at set of rails for said structure, means to secure the structure to said rails, a downwardly extending bracket embracing and extending over the summit of said mound, drums arranged on said structure, a crossbeam secured to chains wound on said drums, and means for rotating said drums.

4t. Mechanism for forming a spoil heap, mound or bank, comprising in combination, cables extending across the point on which the mound is to be formed, a movable structure resting in an inclined position on said mound adjacent the summit thereof for supporting the cables, a set of rails for said structure, means to secure the structure to said rails, a downwardly extending bracket fixed to said rails and embracing the summit, chain or cable drums arranged on said structure, a cross-beam with chains secured thereto and wound 011 said drums, substantially as described.

In testimony whereof I hereto affix my signature in presence of two witnesses.
