Other objects of the invention will appear hereinafter, the novel features and combinations being pointed out in the claims hereto appended.

Fig. 11 is a view taken on the line 11-11 of Fig. 8, looking in the direction of the arrows.
Referring now to the drawings in detail, particularly Fig. 1, a truck frame 5 is mounted on wheels 6 which are adapted to travel on rails 7 of a mine track. The truck frame 5 is provided with longitudinal passageways or recesses 8 to receive the coupling bars 9 and 10, respectively, pivoted at their inner ends at 11 and 12 to the central portion of the truck frame 5. As shown in Fig. 2, the truck frame 5 may be made comparatively heavy so as to enable the wheels 6 to have suficient traction on the rails to stay on the track. The truck frame 5 may be pivoted 85 at 13 and 14 to the axles 15 and 16, respectively. Springs may also be provided, as shown at 17 and 18 in Fig. 2.
Extending upwardly from the lateral central portions of the truck frame 5 are vertical side plates 19 and 20, at the upper ends of which are located longitudinal guides 21 and 22. Between the central portion of one truck frame and the central portion of the next adjacent truck frame is connected a trough having spaced-apart side walls 23 and 24, the ends of which are provided with vertical strips 25 and 26 which extend upwardly into the guides 21 and 22, as shown in Fig. 3.
The bottom of the trough is extended from the central portion of one truck frame 5 to the central portion of the next adjacent truck frame. The bottom 27 of the trough having the walls 23 and 24, has its ends pivoted at 28 and 29 to the truck frame 5. While the coupling bars 9 and 10 are pivoted at their ends to the same bolts that the ends of the bottom 27 are pivoted. it should be noted that the pulling strain between the trucks is taken by the coupling bars 9 and 10,- because the ends of the coupling bars 110 fit closely on the pivot bolts 11 and 12, while the ends of the bottom 27 have a loose fit, as shown in Fig. 1. This enables the trough to have an endwise movement relatively to the truck frame 5, thereby relieving the trough from pulling strain between the trucks.
Referring to Fig. 3, it will be seen that the ends of the bottom 2'? of the trough having the walls 23 and 24 are provided with edges 30, and 32, 32' which extend angularly from the pivots 28 and 29 toward the ends of the truck that are adjacent each other. The adjacent ends of the bottoms of the troughs are therefore provided with angular faces between them so that the train of troughs may move laterally in both directions relatively to the trucks. This arrangement enables the train of wheel-mounted troughs to move around curves in the mine track. For instance, if the train is hauled by a locomotive onto an angular switch-track the ends shown at 30 and 31 in Fig. 3 are free to approach the ends 32 and 33, respectively, while the guides 21, 22 at the sides of the truck frames co-operate with the pivots 28, 29, 34 and 35 to hold the troughs in the desired relation to the truck frames. Meanwhile the blocks of coal are carried in continuous series extending along the train of trough sections. If desired, the ends of the bottoms of the troughs may be beveled at their edges 30, 30' and 32, 32 so as to facilitate the movement of the troughs on their pivots by scraping up from the floor of the truck frame any small particles of coal which may have become lodged thereon.
The train of flexibly-connected troughs, as above stated, may be hauled along the mine track by a locomotive or some other means suitable for the purpose. The flexible connections on the upright axes between the train units readily permit the cars to pass around curves, or onto and off from switch tracks. Furthermore, if there are any irregularities on the tracks, tending to cause the train units to sway sidewise, the sides of the trough will bend to permit this. The troughs are made preferably of sufliciently thin plates of steel so as to be strong enough to handle the coal and at the same time have sufiicient flexibility to permit lateral swaying of the cars without undue strain on the trucks and the connections thereto.
In Fig. 4 is illustrated the form of the troughs at the ends of the train. The end troughs 36 are merely shorter in length, but are otherwise constructed and arranged as above described in connection with Figs. 1 to 3, inclusive. The train of troughs may be open at it ends, but where the train is transported up grade in the mine, removable vertical end gates 37 should be provided. These may be added by sliding them down along the vertical guideways 38 and 39. In order to hold the short troughs 36 in fixed relation to the frame 40, set screws 41 and 42 are mounted in position in the sides of the frame so to be engaged by the vertical angle iron strips 43 and 44 which are secured to the sides of the end trough 36.
In Fig. 5 is shown a roller bearing which may be used for the wheels 6 shown in Fig. 1. This roller bearing construction comprises end plates 45 and 46, secured to the reduced extension 4'? of the axle l5. Spaced-apart wheel bearings 48 and 49 are mounted on the ends of the extension 47. Frusto- conical cages 50 and 51 carry rollers 52 and 53, which rollers are frusto-conical in shape. These rollers are adapted to engage beveled bearing surfaces 54, 54' and 55, 55 on the interior of the wheel 6, the larger ends of the rollers fitting against annular bearings at 48 and 49. Circular gaskets 56 and 57 are mounted in circular recesses at the sides of the wheel 6 in position to seal the peripheral portions of the plates 45 and so from the interior of the wheel 6. All of the parts within the wheel are secured to the axle 15 by means of the bolt 58. In this manner the wheel 6 may be comparatively small and still be provided with the roller bearings shown. In fact the wheel, aside from the bearings, is composed of merely a rim. It should be understood that the end plates 45 and 46, together with the bearings 48 and so, are fixed to the axle 15 and remain stationary. The gaskets 56 and 57 co-operate with the plates 45 and 46 to retain lubricating material in the chamber 6 in which the ball bearings travel and also preclude dirt or foreign material from getting into said chambar from the exterior.
It should be particularly noted that not only is the track bearing surface chilled or hardened, as indicated at 59, but the interior roller bearing surfaces of the wheel rim are also chilled or hardened, as indicated at so and 60' for the roller bearings, is integral throughout. Therefore, by hardening the race-ways for the rollers, the wheel 6 may be made smaller than when additional mechanism to form such race-ways must be placed within the wheel.
As previously mentioned, the mine cars are particularly adapted for use in connection with extensible conveyor and loading mechanism, and this use is illustrated in Figs. 8 to 11, inclusive, but more fully set forth in co-pending application, Serial No. 619,588 granted July 31, 1928, as Patent No. 1,678,821. The extensible conveyor and loading mechanism illustrated in Figs. 8 to 11, inclusive, has been selected from one of the 1 forms of such mechanism originally shown in the above-identified co-pending application. This extensible conveyor and loading mechanism when in use is connected to a mining machine in such a manner as to extend around the corner of a coal pillar into an entry at right angles to the path of the mining machine. The dislodged column of coal is broken into blocks and directed onto the oonveyer and loading mechanism by which it is transported to the train of flexibly connected mine cars and deposited Within the troughs for transportation over the track system of the mine.
Referring now in detail to the extensible conveyer and loading mechanism illustrated in Figs.
8 to 11, inclusive, 62 is a flexible traveling belt for the reception of dislodged blocks of coal A. This belt 62 is adapted to lie on and slide along the mine floor and carry the blocks of coal into the curved chute 63 so as to impinge against the 1 vertical arcuate wall 6% thereof as shown in Fig. 8. The belt 52 ispreferably composed of steel, and is thin, flexible, hard and durable.
The belt 62 extends rearwardly to the winding mechanism 65, which may be operated whenever desired to convey some of the blocks of dislodged coal onto the loading apparatus.
The adjacent sectional columns of coal B have extending under them a conveyer comprising a plurality of spaced-apart wire ropes or cables 66 1 which are paid out fron a winding mechanism, (not shown). An additional rope may be attached at 6'7 to the vertical extension 68. The purpose of this rope will be more particularly referred to in a later part of the description. 1
It will be seen that the ropes 66 extend to a winding mechanism 69 mounted on the base plate 70. This base plate may be suitably anchored by roof jacks 70 and 70 During the operation of the mining machine the ropes are paid out but at such time the winding mechanism 69 is not operated except to maintain the ropes 66 taut; in this respect the operation of the winding mechanism 69 is similar to that of the winding mechanism 65, in keeping the ropes and belt conveyer taut and keeping the blocks of coal in alinement in readiness to be loaded into the train of mine cars, after the mining operation has been completed.
From the chute 63 the blocks of coal are delivered upon a belt 73, which in turn is paid out from a winding mechanism 74. Attached to the free end of the belt 73 is a cross-piece 75 to which a hook is adapted to be connected as at 76, the hook in turn being connected to the free end of a rope 77. The rope 77 is directed around pulleys 78 and 79 to the winding mechanism 80, mounted on the base plate 70. The direction pulleys 73 and 79 are pivoted on a frame 32, which may be held in fixed position by means of a roof jack 82'. When the blocks of coal have been loaded upon the mine cars by the belt 73, the belt is retracted from under the blocks by the winding mechanism 74 after the hook on the free end of the rope 77 is detached from the cross-piece 75.
When the operations are being carried on so that the blocks of coal will have to be moved upwardly along a steep grade, additions will have to be made as follows: From the frame 83 extends a belt or rope 84 to a winding mechanism 85 mounted on the frame 86. The belt or rope 84 passes along the inner surface of one arcuate wall of the chute 63. In a similar manner, the rope or belt 87 extends to the winding mechanism 88 along the inner surface of the opposite arcuate wall of the chute. When the blocks of coal are being loaded the winding devices 85 and 88 are operated simultaneously with the winding devices 65 and 69 to move the coal around the curved chute and up grade onto the belt 73 and into the train of troughs above described.
When the coal is being moved up-grade. it is also desirable to add a belt 89 and extend the same from the winding mechanism 90 over the top of the coal so as to cooperate with the belt 73 below the coal and thus move the latter upgrade into the train on which the coal is to be loaded. For this purpose the frame 82 is provided with two pairs of pulleys. The pulleys 78 and 79 are locatedin position to direct the rope 77, whereas the pulleys 91 and 91 are in position to direct the rope 92. Both of the ropes 77 and 92 are operated by the winding mechanism and these ropes are connected, respectively, at 76 and 93 to the belts 73 and 89. When the winding mechanism 80 is operated the belts 73 and 89 are pulled forwardly simultaneously while being paid out by their respective winding devices 74 and 90.
In order to more efiectively hold the coal in the train of troughs after the belts 73 and 89 have been uncoupled from their respective ropes 77 and 92 and retracted from the train by their respecting winding mechanism 74 and 90, longitudinal lateral pressure devices shown at 94 and 95 may be employed. By referring to Figs. 6, 7, and 10, it will be seen that these pressure devices may be in the form of plates 94 and 95 extending almost to the center of the truck, or the longitudinal center line thereof, and also extending almost the full length of one of the trough units. These plates 94 and 95 may be connected to angles including the vertical strips or bars 96 and 97, on both sides of the train, (see Fig. 6), which are adapted to slide vertically along the guides 98 and 99. The upper ends of vertical bars 96 and 97 are rigidly secured to the friction plate 94 on one side of the train and the bars 96 and 97 on the opposite side of the train are ecured to the plate 95. The lower ends of the bars 96 and 97 are connected at 96' and 97 to a leaf spring 100, which is in turn mounted on the knee plate 101 so as to exert a downward pull on the friction plate 94. The same arrangement is provided for the plate 95 on the opposite side.
The ends of the plates 94 and 95 are curved upwardly so that the coal may be moved under the plates with the upward lifting action against the downward pressure exerted by the leaf springs 100 on opposite sides of the train. The tension of the leaf springs may be adjusted by raising or lowering the knee plates 101 which support the springs on opposite sides of the troughs. To raise or lower these plates 101, the nuts 101 are removed from the bolt ends and the bolts then inserted through upper or lower sets of the openings 101 Adjustable stops are shown at 102 and 103 to limit the downward movement or lower position of the plates 94 and 95. By means of the adjustable stops 102 and 103, the plates 94 and 95 may be adjusted to a higher initial position than the position shown in Fig. 6. In this manner the initial height of the friction plates 94 and 95 may be adjusted in accordance with the thickness of the blocks of coal. The adjustments of the stops 102 and 103 are made by providing a series of vertically spaced openings 102' and 103' in the trough sides and with the stops secured by bolts 102 and 103 engaging in selective ones of said openings. The bolts may be transferred into different ones of the openings so as to raise or lower the stops as desired.
As shown in Fig. 7, manually operated releasing devices 104 and 105 may be provided at the sides of the trucks in position to engage the laterally extending flanges 106 and 107 to lift the friction plates 94 and 95 oif the blocks of coal in the train of troughs when it is desired to unload the coal from the train. These releasing devices 104 and 105 comprise manually operated crank handles 104' and 105' which rotate the curved lifting arms 104 and 105 against the under side of the flanges 106 and 107 and continued rotation of the cranks will lift the plates 94 and 95 to the desired elevation. The crank handles 104' and 105' are connected to the lifting arms 104 and 105 through the medium of worm gears housed as at 104 and 105 and mounted on the crank handle shafts 104 and 105 These worm gears mesh with pinions on the shafts 104 and 105 and the arms 104 and 105 are mounted on these shafts.
The mechanism of the manually operated releasing devices may be supported upon the end of standards 104 and 105 which in turn may be conveniently mounted from the trough sides or on the truck frame.
The use of worm gearing in the manually operated releasing devices 104 and 105 enables these devices to hold the plates 94 and 95 elevated above the coal without the aid of other holding means since the worm will not rotate in a reverse direction in response to the tension of the spring 100. The cranks will therefore have to be rotated in reverse to lower the plates.
These releasing devices 104 and 105 also serve the purpose of relieving the adjustable stops 102 and 103 of the tension of the spring 100 so that the stops may be easily transferred from one of the openings 102 and 103 to another.
