Application filed December 4, 1911. Serial hie. 663,896.

Illinois, have invented a new and useful 1m" provenient in .Matonal-Handling Apparetus. of which the following is e. specification.

My invention relates, more particularly, to apparatus for transferring coal, or the like, from a hopper at one level to bin above the hopper; and my object, generally stated,

is to nnprore upon prior structures of this track from which it may he removed perv character, to the end of rendering them better adapted 01 performing their functions.v

Referring to the accol'npan iing drawings-Figure l is a broken view in elevation of apparatus constructed in accordance with my invention, portions of the structure therein shown being);- illustrated n section, one of the loader-def1ces for controlling the discharge of the 'niaterial" from the hopper l)0lIl 51Sll H\'ll in the position it assumes when in position for receiving a charge from the hopper, and the-other loader-device illustrated being shown in. the positionv it assumes when in position for discharging a.

measured quantity of material into its 00- operating elevating bucket. Fig. 2 is a broken view in vertical sectional elevation taken through the hopper and loader mechanism proper, showing the loader-mechanism in position for discharging into its cooperating bucket. Fig. 3 is a broken section taken at the line 3 on Fig. l and viewed in the direction of the arrow.- Fig. 4: is a view like Fig. 2, showingthe loader-mechanism in the position it assumes While being filled from the hopper.

I have devised my invention felines-more particularly, in elevating coal from a hopper into which it; is discher ed from citrs on a track, to e bin or bins above the level of theodically, or otherwise, as required, such as for instance to load tenders of locomotives, and in. its preferred form it involves, generally stated, the-employment cit two cooperat ng ioader-mechanisins adapted to alternately discharge material, received. froln the hoppers, into hoistii'ip; huchets operating in opposite directions to elevate tlieloatcrial in predetermined amounts to the bin or hide.

though it will be'understood from the following description that certain features of my invention iney be utilized in apparatus in. which but a single elevating buket is employed Referring particularly to Figs. 1 to 9 in elusive, a pair of pits, usually provided in apparatus of this kind, is represented at ll, these pits being located underground in the arrangement illustrated, adjacent side of which are represented at 12. Located above and between these pits is a. hopper 3 which is usually located beneath the ground,

and intowhich the cars not shown) loaded *ith thematerial to he hoisted, discluir .s. The bottom oft-he hopper 13 of 1S iorined two downwaRik -converging sections 1 4 and two upivardbJ-converging int rinediate sections 15. The lower end-portions of the :i tions let are provided with openings lo \vl' form discharge-openingrs at opposite of the hopper for the niaterial perioc ivitl'idrawn there'fron'i in a manner hereii'iafter described, these discl openings preferably being flanked by plates 17 having curved outer edges 18. liocatecl below and registering with each of the discharge-- openings 16 is airincli ned chute 1.9 having a bottom-plate 20 which is formed with a curved section 21 at its upper end at Which it connects with the hopper 13, the plate 20 resting on supports 22 in the pit and "secured thereto in any desired manner to be igid Walls ios ' 'ofa pair of segmental side plates 28 and a curved connecting plate 29 therefor, which latter forms the gate-proper, each gate being of a height substantially equal to the height of the discharge-opening 16 and describing, an arc of? substantially the same radius as the curved edges 18 of the plates 17. The gates 26 are fixed at their plates 28 on trunnions 3O pivoted on and extending through the side walls 24 of the respective chutes 19, the axes upon which these trunnions rotate being the centerof the arcs described by the curved surfaces 18 of the plates 17. The aprons 27 are formed of front plates 31 and rearwardlyextending plates 32 connected thereto, the plates 32 extending beyond. the chute walls 2d at opposite sides of the respective chutes 19, the aprons 27 being pivoted as indicated at 33 to the lower end of the adjacent bottom-plates 20 as re )resented in Fig. 4., whereby the aprons 2 may be swung upon their pivots 33 to 0 on or close the dischargeoutlets 25 of the c mtcs 19 as described, the.

plates 31, when the aprons 27 are in theposition illustrated of the one shown in Fig. L.

serving to prevent the discharge of material from the chutes i9, and when swung downwardly on their pivx ts 33 to the position illustrated in Fig. 2, serving to direct the material, discharged from the loaders, into buckets hereinafter described.

In the construction illustrated, it is intended that the movable aprons 27 be operated with their respective gates 26 "for causing the aprons 27 to be swung downwardly to open condition in the movement of their respective gates to a position in which they close the hopper-outlets 1(3, and be inovedto closed condition in the movement of their onoperating gates 26 to'a'position in which the hopper-outlets 16 are opened, and to effect the simultaneous operation ofthe aprons 27 and gates 26 as described, l-provide the following described mechanisms: Secured to the side-plates 28 of the gates 26 are bars 34 which are connected, through the medium of a rod 35, with the rear ends'of links 36, the forward ends of which links are pivotall connected with levers 37 between the on s of the latter by means of rods 38, the levers 37 being fixed on the outer ends of the trunnions 3O beyond the sides of the chutes 19. The aprons'27 are connected with their cooperating gates 26 through the medium of link-mechanisms located beyond the sides of the chutes 19 and aprons 27, and comprising, in their-preferred form, links 39 pivotally connected at with the upper ends ot' the bars 34 and carrying pins 40 in their lower ends, and links 41 pivotally connected at their lower ends as indicated at42 to the sides 32 of the movable aprons 27 at opposite sides thereof at a distance from the pivot 33 less than the distance from. the pivot 30 to the oint'35, and containing elongated slots 4:3 in their upper ends through which the pins 40 extend, and through the medium of which pins the-links 3 and 41 are pivotal! connected together by a slide connection. The

lower ends of the links 39 are shouldered as represented at. 44:, these shoulders fitting against stops, shown as cross-pins 45, carried by the links 41 when the links 39 and 11 are in alining position, as represented in Fig. 4.

The arrai'igement of the parts described such as to cause the gates 26 to be open when the aprons 27 are in position for closing the chute-outlets 25, and in this position of the gates 26 and aprons 27 the axes upon which the trunnions 3O rotate are slightly out of line with the pivots 35 and 42, as represented in Fig. 4:, though it is Within my invention to so arrange the lever-mechanism that the trunnion axes and pivots 35and 42 will be in alinement.

It will be understood from the foregoing that when the hopper 13 contains material such coal, this material, when a loadermechanism is in the position illustrated in Fig. 4, Will flow into the chute 19,'the escape therefrom being prevented by itscooperating apron 27, and when the levers 37 are rocked downwardly, the gate 26 will be swung upwardly to shut off the flow of coal from the hopper, and the apron 27 sWung I downwardly to permit the charge in the chute 19 to discharge into a cooperating hoisting-bucket hereinafter described. Swinging the levers 37 upwardly to the position illustrated in Fig. 41- will cause the illustrated in Fig. 1, namely wherein the gate 18 withdrawn from registration with the chute 19.

Pairs of guides extending upwardly from the bottom of the pits 11 are represented at to, these guides, in practice, extending to a point closely adjacent to the receiving-bin or bins (not shown) and serving-as guides 'for hoistin buckets one of whichis illustrated at 17 for periodically receiving ma- 'terial from the hopper-bin 13 through the medium of a loader-mechanism described.

In the construction illustrated, the buckets.

4:7, operating in the guides 46, are intended gate 26 and apron 27 connected therewith to be sin'iultan-cously moved to the position end, to the left in Fig. 9 the bucket turning on the shaft 57 and finally seating on both of the supports 60 beneath it in an inclined position. as represented in Figs. 1 and 9, wherein it is projected at its upper openend a slight distance beneath the apron 27 cooperating therewith. In the operation of raising the bucket 47 from the position illustrated in Figs. 1 and 9, the bucket is first raised from the support 60 at the left-hand side of Fig. 9, the bucket. rotating on its shaft 57 until this bucket engages with the shaft 59, by this operation the bucket being withdrawn from a position in which it eX- tends under the apron cooperating therewith, and may be lifted Without disturbing the'position or' the loader-mechanism.

By the arrangement of the connection be; tween the ate and door abpve described'for the gates'26 and aprons27, it will be readily understood that when the levers 37 are swung downwardly from the positionillustrated in Fig. d to the position illustrated in Fig. 2,.the gate '26, in its initial upward 'movement, will move at. a much greater speed than the speedat which the apron 27 swings downwardly in the initial movement of the latter, and the apron 27' in its final downward movement will move at a greater speedthan the speed at which the cooperating gate 26 travels in its final clos--- mg movement and thus the gate '26 ischarge from said chute over the apron 27.,

The gate 26, lmwever, is caused to move through running coal when swung upwardly, as stated, by reason of the displaceinent oi the coal 1n the chute 19 caused by the lowering ol" the apron 27 in its initial movement, supplemented by the action of the gate 26, the gate-proper 29 of which by. being preferably spaced from the curved portion 21 ot' the chute-bottom. 20 operating as .1t swings upwardly to open to the coal in the chute 19 the space between the plate 29 and bottom 21, tl1us,in eliect, progressively enlarging the coal-filling space afforded in the chute 19 as the gate 26 swings upwardly, it being preferred that the chutesections 21 and the plates 29 be of such contour and so arranged that the spaces between these parts become gradually shallower troin front to rear when the gates 26 are in open condition as represented in Fig. l, in the construction illustrated this arrangement beinge'liected by forming the plates 21 and 29 of aroshape and arranging thein in non-concentric relatiomthe plates 29 being movable adjacent to the upper ends of the coiiperating plates 21 in close proximity thereto so as to prevent'lumps of coal 'from becoming wedged between the plates 21 and 29. In the act of swinging the gate 26' and movable apron 27 back'to the posi tion illustratdd inFig, 4, the apron 27 in its initial upward movement closes very rapmechanisms from the position illustrated in,

Fig. a, as the crank-connections between the gate 26 and the movable apron 27 and Comprising the bars 3 1 and links '39 and 41, are substantially ondead' center, and the force exerted by the coal lying uponthe plate 29 is sullicient to overcome the leverage exerted by the links 39 by reason of the pressure of coal against the plate 31.

In the movement of "the loader-mecha nisms to discharging position represented in Fig 2, lugs 27 on the sides ofthe aprons 27 are engaged by the links 41, causing the links 39 and 41 to swing forwardly and dis- 'e'hgage.the shouldered portions 44; of the links 39 'from the pins 45 as illustrated in Fig. 2, this feature of the construction being provided for the purpose of permitting -thelrprons 27 to swing upwardly without ,opgratihg their cooperating gates 26 should the apparatus become clogged in such a way astd cause the coiiperating buckets 4:7 to exert, in their upward movement, lifting action on the aprons 27, it being understood that the feature just referred to of theconstruction is provided for the purpose o'i' preventing damage of the apparatus or unin- 'tended discharge of coal through said chutes 19 in case theebuckets 47 in their upward movements exertylifting force on the aprons 27.

The construction illustrated in Fig. 10 shows a modification of the means for tilting the bucket l'r' toward the loader-mechanism when the arrangement of the hopper 13 and thereceiving-bin or bins to be sypplied therefrom occupy such positions, as they sometimes do in practice, as to render it. necessary that the buckets 4713c filled from the side opposite to that illustrated of the one on the right=band side in Figs. 1, 2

and 4. In the case of this modification, the.
