Pow is or portable illk'li fli' of 60-. indicated in ign g-fllt'li'ili vim power nmyf' i: t moms of my How? shafts as 31, FF; vidgd with 00 Also unit idiy index 13m delivery endmeshing with bevel gear on shaft 9 of said drum 7. For taking up slack in belt 6 drum 8 may be mounted in slidable boxes 16, 17,

and idle drum 18 adjacent to drum 7 is preferably su plied under the lower run of said belt for t e support thereof. The rear end of said unit is supported on swivel casters as 21, mounted in frame 25 and the delivery end of said unit is provided with sockets 26, 27 for thereceptign of-removable wheeled supports as 10, 11.. The rear or receiving end of said unit is provided with seat 19 and latches as 23 for the reception and retention of a hopper as 24. Also the delivery end of said unit is provided With means such as sockets 28, 28 for the reception of thehinge members of swinging guides or wings 34, 35. All the features of the conveyor unit which have just been described are common to all conveyor units in my improved apparatus.

The following parts and devices are used only on the first unit 5. To wit, hopper 24 for the initial reception of the coal from hoisting bucket or elevator; the receivin r lip 240 of this hopper may pro'ect outwar ly from the bunker porthole 1f esi'redor delivery of coal thereto may be made through an auxiliary hop er not shown. Removably secured to side p ates 12, 13 is cross bar 29 on which are 'sup orted blades 36' preferably alternately ong and short and which blades serve as a screen for separating the larger lumps of coal from the general mass passln along on belt 6. Said blades are incline upwardly from their receiving ends and said receiving ends, of at least a'portion of said blades lie in close proximit tobelt 6 so as to readily receive. thereon suc lumps of coal as are conveyed thereto. The central blade of blades 36 preferably extends upwardly and forwardly beyond. the upper ends of the other blades 36' and said other blades are shorter and shorter at their upper ends as they near side plates 12, 13 whereby any lumps passing upwardly thereover will be discharged sidewlse from said blades. Under the upper or d ischa rge ends of said blades 36 ,are secured plates 37 inclined downwardly from under the center blade and 0X- tending over and beyond side )lates 12,13

whereby luln. s discharged by rails 36 willi'be deflected an discharged sidewise outside ofsaid conveye'r. It is obvious that rails or blades may be substituted for dates 37 with equal efficiency. Also mounted on side plates 12, 13 is shaft 38 on which are fixed lifters or spiders 39 for assisting said lumps onto blades 36 and forcing them upwardly there over. Shaft 38 may be provided. With sprocket 40 thereon and to which powermay'fj be communicated by means of chain 41 ' plates 12, 13 are swinging guides or wings 34,;-

35 respectively, for deflecting the coal from belt 6 onto the next succeeding belt. Said 7 are hinged vertically to the line of travel of the working face of belt 6 and the hinges 44, 45 thereof are provided with springs as 55 for urging the depending portions of said Wings outwardly for en agement' with side plates-120, 136 respectively. Saidwings 34, 35 are also efficient to maintain the receiving portion of conveyor 50-111 receiving position under the delivery end of conveyer 5. The only part that usedoh the last unit as 50, that is not common to all. the conveyer units, is forward wheeled carriage 46 and which carriage lS'TGD'lOVBblY attached to said unit 50 by means of sockets 26, 27 thereon. Said carriage 46 is provided with as: r

47 pivoted at 48 therein for engagement with rotary shovel 20. v

Diectar ing medns.-Reierring now more particular y to Figs. 5, 6 and 7 the discharge element of my improved apparatus, ind-i cated in a generalwayby 26 (Fig. i), comprises-a horizontal shaft 60 mounted insultable bearings 61, 62 reinovahl attachedto frame 63 by lock pins 64, 64.1 ester is com- .municated from flexible shaft 32 through bevel gear'fifi shaft 60. Fixedto shaft 66 arstvro disks thereon'to hovel gear 6660p 1 1 66, 66between which are plvotally mounted.

a plurality of shovel blades 6'7, 67 .""Said blades are pivoted on pins as 68,, 6S and'are I normally held against stops 69,69 on disk 1::

66, 66 by means of pull springs '56, 70 all: re: speetively. Said yieldabie mounting of b ades. 67, 67 is proyided so that whensaid blades strike lumps or other obstructions or encounter an overload they may yield bar-l:- wardly relative to their direction of travel and thus tern o'raril relieve themselves while springs 70 being thus put under in creased tension will promptly restore said blades to their normalposztiens. Also it will be observed, see dotted: position of blade at 6 70 Fig. 6, that said. f with. a so pivoted relative to shaft 60 .tha't.v shown and described their-enter edges as 60-7 are lifted away from pan-71 therebyafiording 1 additional relief from-undue strain botlrto as they yield as the individual blades and to the shovel as a.

whole and to' the driving mechanism therefor: If desired said blades 67, 6'7 inay be pivoted by their inner edges directly to 60 and spring sustained all within the scope of my 5 pan 71 having sidesiYQ-fiQ upstanding therefrom. Said pan is red to cross plate 76 of frame 63. The-reaia'ard end 73 (Fig. 1) of said pan 71 is flared out into a receiving portion. Frame 63 isprovided with a pivot ear 7 4 for engagementwith link 47 of carriage 46 so thatwhen rota-ryshovel'20 is swiveled in the horizontal plane; said portion 73 will always he in receiving POSllSlOIl under the delivery end of conveyer50. Carriage 63 may it be rovided' With'easters 7 5, 75 to facilitate sair horizon'flal-s t'itfdling and its general movement. -5

For directing-the discharge of shovel 20, I have supplied one'or more shii'table deflectors as 77, 78 pivotally mounted concentrio with shaft 60, by means of arms as 7 9, 80 on sleeve (510, 620 inreaching frombearings 61, 62a peotively. Said deflectors ay be provid with sides as 83, 84 and ma bo secured inwany desired position by means of clamps as 81 operatod'by levers as 82. By means of my improved"arrangement including fixed pan 71 and shiftable deflectors 77, 78 the stream of material delivered by blades 67, 67 may be directed in the vertical plane from a forward direction slightly above the.

horizontal, see arrow S30 fiptof'arear- Ward horizontal direchmm'jsee agri jow 840 Fig. 5. v i

with the frontedge of deflector 77 raised to the positionindicated by dotted lines at770, deflector 75S'is maintained, in an idle position as shown in said Fig. 6. When it-is desired to discharge rearwardly deflector 78 is moved into operative position for eoaction with deflector 77 and pan 71, as shown for instance indfig. 5. By withdrawing lock ins 64, 64 theErotary portion of shovel 20 an the deflectors therefor may be removed from 5 frame 3 and pan 71, to facilitate handling and the introduction to and removal from the bunker.
