To all whom it may concern.-

Be it known that I, AUGUST Lunwre EMIL BERGERT, a subject of the German Emperor,

residing at Johannesburg, Transvaal, have invented certain new and useful Improvements in Means for Distributing Mine Residues and for other Similar Purposes, of which the following is a specification.

This invention relates to means for distributing mine residues or to apparatus designed for conveying to and dumping or depositing such residues upon a mine-dump or depositing-site. 'Apparatus constructed in accord ance with the invention may also be employed for conveying to and depositing or distributing over a limited area any kind of granular, pulverulent, or fragmentary substances or materials.

The invention has reference more particularly to that kind of apparatus in which a boom or jib which supports an endless conveyer-belt is mounted upon and carried by a carriage or wheeled frame which is arranged to traverse a track or rails laid upon the dump or depositing-site and along which track it may be advanced to cause the delivery end of the belt to overhang the top or face of the dump as the latter is filled up or extended. At. or about the center of its length this boom in'previously-proposed constructions has been supported on a carriage which is arranged to traverse a radial track carried by the wheeled carriage or vehicle traversing the main track to enable the boom to be swung into position to deposit the material at either side of the main track. In constructing an apparatus in accordance with the present invention this boom or jib is at its rear extremity pivotally supported in 'a frame, so that it may move in a vertical plane about its pivotal connection with said frame, said frame being pivotally supported in such manner as to allow the boom to swing in a horizontal plane or to either side of the main The boom at or in proximity to its I forward end has pivotally attached to 1t a.

track.

trestle or support which serves for supporting the boom after it has been brought into the desired position for dumping. For the purpose of raising or lowering the boom an arrangement is provided comprising a bridle or frame pivotally attached to the front end of the boom, which bridle or frame carries a suitable arrangement of pulleys carried by a structure erected up on the carriage or wheeled frame, the rope being'wound round the drum of a winch which serves for hauling it in or paying it out to raise or lower the boom as required.

A motor of any suitable construction is mounted upon the boom and serves for driving the conveyer-belt. The material is received from a main feedbelt, which may be driven by means of a suitable motor mounted upon the wheeled frame or carriage which delivers the material into a hopper communieating with a chute which conducts it onto the receiving end of the conveyer-belt. This chute is attached in a suitable manner to the frame, which pivotally supports the boom, so that as the boom, and with it the frame, is moved to either side of the track the chute is at the same time moved so that it is maintained in such a position in relation to the belt as to cause the material to be delivered onto the belt and in the direction of motion of the latter. Guide-plates may be provided running parallel with the edges of the conveyer-belt for some distance in advance of the lower end of the chute, so as to guide the material onto the belt as it leaves the chute. These guidelates are at one end pivotally attached to t .e lower end of the chute and at the other end are pivotally attached to brackets or supports which at their other ends are pivotally connected to the sides of the boom. This allows the guide-plates to move in consonance with the vertical movement of the boom when it is raised or lowered.

' To facilitate the detailed description of my nvention, 1 append two sheets of explanatory drawings, which are marked with figures corresponding to the following description:

Figure 1 represents the apparatus in side elevation. Fig. 2 represents it in plan with the upper carriage and parts carried thereby removed. Fig. 3 is a view of the frame detached, in which the rear end of the boom is pivotally supported. Fig. 4 is an end elevation of the upper carriage or the front posts 21 and the members connecting the same, the front inclined or overhanging members 43, and the parts carried by the latter. Fig. 5 is an end. elevation of the upper carriage or rear posts 21 and the members connecting the same, this figure standing 011 end. Fig. 6 is a plan of certain members of the upper frame, showing the bracket 56 fixed thereto and carrying the collar-bearing for the frame 49. Fig. 7 is a plan of a portion of the upper frame, showing the main feed-belt, hopper, and a portion of the gearing for drivin the belt. Fig. 8 is a transverse section 0' the boom, showing the trestle for supporting the forward end of the boom, drawn to an enlarged scale; and Fig. 9 is a plan of the pulleys for the rope which serves for raising or lowering the boom.

The carriage or wheeled frame 1, upon which the apparatus is mounted and transported, is adapted to traverse a track or line of rails laid upon the surface of the dump or depositing-site, (represented at 2.) This carriage comprises at each side two parallel U or channel irons 3 4, between which are located wheels 5, upon which the carriage traverses the rails or track. The sides or longitudinal channel-irons 3 4 are connected at the back or at their rear ends by the two parallel channel-irons 6 7, which are riveted or otherwise suitably fixed to said longitudinal members 3 4.

8 represents gusset-plates which serve for connecting the transverse channel-iron 7 at its extremities to the channel-irons 4. The two transverse channel-irons 6 7 are connected by the latticed or diagonal angleirons 9. At the center of the transverse members 6 7 is riveted a plate 10, which pro jects for some distance beyond the member 7, as shown in Fig. 2. The plate 10 is stiffened by means of the channel-irons 11, located beneath it at the edges and between the transverse members 6 7. These channelirons 11 also serve for connecting said mem bers 6 7. Toward the forward end the longitudinal members 3 4 are connected by the two other parallel channel-irons 12 13 and gusset-plates 14, these transverse channelirons 12 13 being also connected by the latticed or diagonal angle-irons 15. At the center of the transverse members 12 13 is riveted a plate 16, which extends in both directions beyond the two members 12 13. The forward ends of the longitudinal members 3 '4 are connected by plates 17, which are shaped as shown in Fig. 2. To these plates 17 are riveted the diagonal angle-irons 18, which at their other ends are riveted to the under side of the plate 16. Between the channel- irons 7 and 13 are provided the diagonal angleirons 19, which are riveted to the gussetplates 8 and to the plates 10, 14, and'16, car ried by the two transverse latticed girders 6, 7, 12, and 13. 20 represents two parallel angle or U irons located at the center or midway between the sides and riveted at their ends to the plates 10 and 16.

The above described members form a rigid under carriage for the wheeled vehicle. On this undercarriage are erected four vertical posts 21, (see Figs. 1, 4, and 5,) each consisting of two parallelU or channel irons. These posts are connected to the longitudinal members 3 4 of the under carriage by means of plates 22. In Fig. 5 I illustrate the members connecting the two rear posts 21. As shown, they consist of two transverse U- irons 23, one at the top and one at the bottom of the posts and fixed thereto by means of plates 24. At the center of these .two transverse U-irons 23 are riveted two plates 24, and to the plates 24 are riveted diagonal and vertical angle-iron stays 25 26, re spectively, which brace together the transverse connections 23 between the two rear posts and form a rigid frame. The two front posts 21 are, as shown in Fig. 4, connected at the bottom by means of the angle-irons 27 and at the top by the two channel-irons 28, which are arranged between the posts and the channel-iron 29, placed at the back of the posts. These several transverse members are connected to the posts 21 by the plates 30. The two parallel channel-irons 28 are connected by the latticed angle-irons 31. At the center of the angle-iron 27 and at the center of the bottom U-iron 28 are riveted plates 32, to which plates are connected the diagonal angle-irons 33, which latter at their other ends are riveted to the gusset-plates 30. 34 represents two parallel and vertical angle-irons riveted to the plates 32. These several parts form a rigid frame transversely of the under carriage between the two front posts 21.

The posts 21 at each side of the carriage are connected at the top longitudinally of the under carriage by means of two parallel channel-irons 35, which, as shown in Fig. 1, are riveted to the gusset-plates 36, which gusset-plates 36 are also riveted to the posts 21.

37 38 are intermediate channel-irons connected to'the channel-irons 23 29 by means of the gusset-plates 39.

40 represents diagonal angle-irons riveted to the gusset- plates 39 and 36 The three channel-irons 38 are extended for some distance in a forward direction beyond the channel-iron 29 for a purpose to be hereinafter explained. (See Fig. 1.) The several channel- irons 35, 37, and 38 and diagonal angle-irons 40 rigidly connect the vertical transverse frames between the posts. The ends of the frame are also connected by the channel-irons 41, which form bracingstruts for the vertical posts. These channel-irons 41 at their upper ends are riveted to a gusset-plate 42, riveted to the channelirons 35 (see Fig. 1) midway between the posts 21, the channel-irons 41 being at their other ends riveted to the gusset-plates 22,

connecting the posts 21 to the under carriage.

The structure comprising the posts 21 and their connections above described form a rigid frame for carrying certain parts of the apparatus hereinafter described. This part of the carriage is hereinafter designated the .upper carriage.

On the upper carriage is erected a superstructure consisting of two front members 43 and two rear members 44, the two front.

members each of which, as shown in Fig. 4, consists of two parallel channel-irons. These two front members 43 are at their lower ends riveted to the gusset-plates 36, which connect them to the posts 21 and longitudinal channel-irons 35. They are inclined toward each other and meet at the top and are also inclined in a forward direction, .so that they overhang the rear end of theboom, as shown in Figs 1 and 4. They are connected by means of a curved plate 45. The two rear members 44 each consists of a channel-iron riveted to the channel-irons 43 at the upper ends and at their lower ends riveted to the gusset-plates 36 and longitudinal channelirons 35.

The boom, upon which is mounted the end less conveyer-belt 46, comprises the two parallel channel-irons 47. The rear end of this boom is supported upon a pivot 48, carried by a frame (see Fig. 3) in such manner that the boom can be raised or lowered about the pivot 48. This frame, as shown in Figs. 1 and 3, comprises four channel-irons 49, connected at the sides and ends by the gussetplates 50. (See Fig. 3.)

51 represents blocks fitted to the channelirons 49 for affording a bearing for the extremities of the pivot 48. Similar blocks 52 (see Fig. 3) are also fitted in the channel irons 47, forming the boom, for the samepurose. p The frame 49 is=co nstructed top and bot tom with a cylindrical projecting piece 53, about which the frame 49 may swing to permit the boom to be swung horizontally or to either side of the main track. The projection 53 at the bottom of the frame 49 fits a bearing 54, (see Fig. 1,) fixed on the plate 16 on the latticed girder 12 13, while the other pivot or projection 53 runs in a collar-bearing 55, carried at the forward end of a bracket 56. The bracket 56, which is riveted or otherwise securely fixed between the two channel-irons 28, consists of two curved plates shaped, as shown in Fig. 6, connected round the edges by curved angle-irons 56 The top pivot 53 of the frame 49 is extended and is fashioned into or constructed with a flange 57, to which is riveted the chute 58, which serves for directing the material onto the conveyer-belt 46. To the lower end of the chute 58 and arranged above and parallel with the edges of the belt 46 are hingedthe rear ends of guide-plates 58 which plates at their other ends are pivotally connected to brackets 58*, which brackets at their lower ends are pivotally attached to the sides of the boom 47.

The two parallel members 47, forming the boom, are connected transversely by the T- irons 59, to which are fixed the brackets or supports 60 for the belt idlers or rollers 61,

upon which the belt 46 runs. (See Fig. 3.) The belt-idlers 61 are arranged in groups at suitable distances apart, each group comprising the two inclined rollers and the horizontal roller at the rear of said inclined rollers. This arrangemnt of idlers 61, which forms no feature of my invention, causes the conveyer-belt to assume the trough or concave shape for receiving and conveying the material. The return-idlers 62 are carried by a spindle 63, which runs in brackets 64, carried by the lower flange of the channelirons 47 of the boom. (See Fig. 3.)

To the rear. end of the boom 47 are fixed bearings for a horizontal shaft 65, to which is. fixed the belt-pulley 66, round which the conveyer-belt 46 passes. at one side projects beyond its bearing and has fixed upon it a driving-pulley 67. (See Fig. 2.) A structure consisting of the vertical and horizontal channel-irons 68 is fixed to the boom and provides a platform or support for an electric or other suitable motor 69, which is employed for driving the conveyer belt 46. fixed a pulley 71. Another shaft 72, which runs in bearings provided for it in the boom 47, has fixed on one extremity a large pulley 73 and on the other extremity a small pulley 74. The small pulley 71 on the motor-shaft drives the large pulley 73 on the intermediate shaft 72 by means of the belt 75, andthe small pulley 74 011 the other end of the intermediate shaft 72 drives the pulley 67 on the end of the belt-pulley shaft 65 by means of a belt 76. (See Fig. 2.) The several pulleys are of such dimensions that the speed of the motor-shaft 7 0 is reduced. to impart a suitable speed to the conveyer-belt 46. The pulley 77, which is provided at the other and forward end of the boom for the conveyerbelt 46, is preferably constructed with adjustable bearings for taking up any undue sag or for adjusting the belt 46, as may be required. The bearingblocks 78 are adapted to be moved, by means of the screws 79, longitudinally of. the guides 80, riveted to the sides of the boom.

In proximity 'to the forward end of the boom is hinged or pivoted a trestle which serves for supporting the boom when it is conveying the material and so prevents the transmission of any strains to the ropes and means provided for raising and lowering the boom. This trestle consists of two channelirons 81 at the bottom, connected to angleirons 82 at the top by means of the channelirons 83. The upper ends of the two outside channelirons 83 project up the sides of the channelirons 47 of the boom and carry blocks 84, through holes in which passes the The spindle or axle 65 spindle 85. 86 designates nuts screwed on the outer extremities of the spindle for connecting the parts. In Fig. 1 the trestle is shown in the position into which it is' brought to support the forward end of the boom 47, and in Fig. 8 timbers 87 are shown supporting one end of the trestle when the surface upon which it is lowered is uneven, so as to maintain the boom horizontal and prevent any strain being placed on the frame 49 and on the pivot 48, supporting the boom in said frame.

For the purpose of raising and lowering the boom as may be requiredas,for example, when advancing it along the rails, so that the forward end of the boom overhangs the face of the dump 2I provide an arrangement consisting of two flat bars 88, (see Fig. 1,) one pivoted to the outside of each of the two channel-irons 47, forming the boom. These 'bars 88 are bent inward or inclined toward each other and at their other ends carry between them a pin or spindle on which is loosely mounted a pulley 89.

At the top of the superstructure and between the channel-irons 43 is secured a block 90, formed with a vertical hole, in which is located a pivoted bracket or rotatable arm 91. The arm 91 is formed at the top with a collar 92 and bifurcated or constructed with two arms 93, between which is arranged a spindle 94, on which is mounted a pulley or roller 95. (See Fig. 9.) The lower end of the arm 91 is curved in a forward direction, as seen in Fig. 1, and terminates in an eye 96. To this eye 96 is attached a wire or other suitable rope 97, which passesround the pulley 89 and then back over the front vertical pulley 95. To the top of the superstructure at the rear of the front pulley is fixed another block 98, which is constructed to provide bearings for spindles 99, on which are mounted the two horizontally-disposed guidingpulleys 100, between which the rope 97 passes after it leaves the front pulley 95. The block 98 is also constructed to provide bearings for another spindle, on which is mounted a back pulley 101, round which the ro e passes after it leaves the horizontal gui epulleys 100. The rope then passes over another pulley 102, carried by a bracket 103, fixed to the angleiron 44 or channel-irons 35. The rope then passes down and is wound round the drum or winding-surface of a winch 104, which is shown carried by a plate 105, attached to one of the back vertical posts 21 or the frame built upon and between them. By actuating the winch 104 the rope 97 may be hauled in or paid out to raise or lower the boom 47, as may be required, in a manner that will be well understood.

The main feed-belt, which serves for conducting the material to the distributing apparatus, is represented at 106. It passes round a pulley 107, which is fixed to and rotated by a spindle 108, which runs in bearings provided for it upon the forward exten: si,ons of the three channel-irons 38. (See Fig. 7.) On this spindle 108 is fixed a pulley 109. On the channel-irons 38 are provided the four bearings for another horizontallydisposed shaft or spindle 110. On this lat.- ter spindle 110 are fixed a small pulley 111 and a large pulley 112. The small pulley 111 drives the large pulley 109 on the feed-belt pulley-shaft 108 through the belt 113. At the back of the carriage and mounted upon the plate 10, fixed to the top of the under carriage is an electric or other suitable motor 114, (see Figs. 1 and 2,) on the shaft of which is fixed a pulley 115, which drives the large pulley 112 on the shaft 110 by means of the belt 116. By the means above described the main feed-belt 106 is carried by the traveling structure and driven by the motor 1 14, which is also carried thereby.

To the forward ends of the extensions of the channel-irons 38 is riveted or otherwise suitably fixed the hopper 117, (see Figs. 1 and 7,) arranged immediately beneath the bend of the main feed-belt pulley 107, so that as the material is conveyed along the belt 106 it is delivered or falls off the latter into said hopper. The hopper 117 communicates with the chute 58, which rotates with the frame 49 when the boom 47 is moved to either side of the main track, as previously described.

Instead of constructing the under carriage, the upper carriage, and the superstructure, the boom, and other parts of the apparatus of the particular section or sections described any other suitable section or sections can be employed in substitution therefor, or, if desired, certain parts of the apparatus may be built up or constructed of beams of wood or other suitable material.

The mode of manner of using the apparatus is obvious from the foregoing description. In Fig. 1 the boom 47 is represented in its central position-that is to say, midway between the rails forming the track for the wheeled vehicle or carriage 1. In this position the material being conveyed by the belt 46 is being thrown over the edge or down the face of the dump 2, so that, the dump is thereby being extended in the direction of the main track. When the dump has been filled up within the range of the boom in a forward direction, the boom is raised off the trestle by means of the winch 104 and rope 97, which raises the boom 47 vertically about its pivot 48 in the frame 49. It is then swung about the vertical pivots 53 of the frame 49 to one side of the track and lowered onto the trestle and the dumping continued until the dump at that side of the main track is filled up. The boom may be placed in one or more different positions at the side of the track so as to fill up the dump more completely. The boom is then raised and swung to the other side of the track and the dumping continued at that side in a similar manner. When the dump is filled up in all directions within the range of the boom, the wheeled vehicle or carriage is then advanced or moved forward up the dump along the main track until the boom again 0 verhangs the face of the dump and the dumping continued.
