APPARATUS FOR HANDLING LOOSE MATERIAL.

Specification of Letters Patent. Application filed ma 10, 1909.

Patented July 4, 1911. Serial No. 495,131.

To all whom it may concern:

lie it lnlown that I, ROBERT A. OGLE, a citizen of the United States, residing at Chicago, in the county of Cool; and State of illinois, have invented a new and useful lnun'ovement in Apparatus for Handling Loose Material, of which the following is a specification.

lily invention relates to improvement in apparatus for handling loose material and, more particularly, to apparatus intended for use in transferring coal, or the like, from a hopper at one level to a bin above the hopper; and my object is to providean apparatus of the character referred to which shall be simple 0t COHStl'UCtlUD, durable and positive in operation, and, in general, particularly adapted to perform the functions of apparatus of this character to thebest advantage.

Referring to the accompanying drawings--Figure l'is'a View in elevation of apparatus constructed in accordance with invention, portioh'sof the apparatus being shown in sectional*elevation to better disclose details, the view being broken to better illustrate the apparatus. Fig. 2 is a vertical sectional elevation taken through the hopper and loader-mechanisn proper at one side of the hopper. Fig. 5 is a view showing one of the two similar loading mechanisms in front cle'vatio1'1. the po. 'tion of the loader being that reprewntcd o'l' theoneshown on the right-hand side of Fig. l; and Fig. a View similar to l ig. 1 showing"; a modification ol' the loadcr-mechunisnifand its operat. ing means.

I have devised my invention For use, more particularly in Ll(..\ttl'l1 ft7:l from a hopper into which it is discharged,lroni cars on a tract: to lJlllr-f above the tract: l roin which it in v be removed )(fllOtlllftlll t or I otherwise, as required. such as for ihstancc to load tenders oi locomotives, and,in its 'n' etcrred l generally stated, the use (it two loader-incchanisnis adapted to alternately discharge material received from the homiers into hoistirig-buckets operating in opposite directions to elevate the material in predetermined amounts to the bins,

thougjhit will be urnlcrstood, as hereinafter set forth, that certain features otthe invention are not limited in their use to apparatus employing a plurality of buckets.

Referring particularly to Figs. 1 to 3, inclusive, a pair of pits usually employed in apparatus of this kirl is represented at 5,

these pits being located. underground, and

adjacent side walls thereof being illustrated at 6. Located above and between these pits is a hopper 7, which is usually placed underground and into which loaded with the material to be hoisted, discharge. The bottom of the pit 7 is formed of two downwardly converging sections 10 and two upwardly converging sections 11. The lower end-portions of the sections 10 are provided with openings 11 which form discharge-openings at opposite sides of the hopper for the material periodically withdrawn therefrom in a manner hereinafter described, these dischargdopenings preferably being flanked by plates 12 having curved outer edges as represei'ited at 13. Located below each of the discharge-openings 11 is an inclined chute 14. formed of a bottom-plate 15, having a. curved section 16 at its upper end which is connected with the lower edge of the adjacent section 11 of the hopper 7, the bottom plate being supported upon a series oi timbers 17 connected with the wall (3 at their upper ends and SUPPOl'lZCd on timbers 18 toward their lower ends, this plate being preferably limltcd to these timbers as indicated at lt); side-members 20 spaced apart a distance slightly greater than the width of the discharge openings 11 and extending upwardly to within a short distance ot the lower edge of the adjacent section ll; and a curved front-plate 21 carried by the walls 90 and spanning the space between them, the forward portions of the plates 20 terminatingin extensions 22, which latter form. with the lo\.er end-portion ot the plate 1.5, the open discharge-end ot the chute. ,l ach of the open-topped chutes 14 thus provided at opposite sides of the hop per 7 below the outlets 11 thereof, partially houses a measuring receptacle 23. which is cylindrical in form as represented, and formed (it ends fld'ot'disk-shape and a shell, or wall, 25, the upper half of the shell being cut away. as clearly represented in Fig. 2. The receptacles thus provided are pivotally the cars (not shown) insuring the. desired rigidity of the receptacles, Iprefer tobrace each pair of heads by a rod 29 connected at its opposite ends with its respective heads, as illustrated. Inthe operation of the apparatus, the receptacles 23 serve, at their open upper sides, to receive the material from the hopper 7 and at the proper time be rotated u on their journals to cause their open si es to be moved into registration with the outlet-ends of the chutes 14 for effecting the discharge of their contents into a receptacle hereinafter described, the curved walls 25 of the receptacles, when thus operated, servingto be moved across the outlets 11*, and thus prevent flow of material from the bin through these. discharge-openings while the receptacles are discharging. A pair of holstlng buckets for periodically recelvlng material from" the bin 7 through the medium of the receptacles 23, are represented at 30 and 31 as operating in guides 32 and 33,

which extend upwardly from the bottoms of the pits 5. It will be understood that these.

guides rise sutlieiently far to. permit the buckets to be raisedlto a height enabling them to be discharged into a receptacle, or

bin, (not shown), which may be located as far above the hopper 7 as is found desirable. In the construction illustrated, thebuckets 30 and 31 are intended to be operated si nulf taneously, but in opposit directions, and, in accordance with an arrangement'well known 'lI1 the art, are so-associa'red with hoisting mechanism (notshown) of any desired construction that when one of the buckets is at the bottom of the pit, the other is at the top of its respective guide. Fig. 1. is intended to represent the bucket 31 at the height of its upward travel, in which position, in practice it would be raised sufliciently far to permit it to be dumpedinto the bin. The receptacles 23 are designed to be automatically operated by the movements of the buckets, and to effect this, in the preferred construction, I fix on the stub-shafts 26 be yond. the heads 24: of the receptacles 23, sheaves 3ft and 35, about which sheaves 3 k a cable 36 is wound, this cable being connected at its opposite ends to an end of each of two cross-bars 37 normally resting against pairs of upright guides 38 paralleling the guides 32 and 33 to extendinto the path of downward movement of the buckets 31 and 32, this cable also extending over idlerpulleys 39 which may be located at any convenient point'in the apparatus. The sheaves 35 have cables 10 partially wound upon them and fixedly secured thereto, the free;

which the cable 36 connects.

end of the cables 10 being connected with the ends of the rods 37 opposite to those at The cable 36 is initially wound upon the sheaves 34 in a position to cause the cross-bar 37 cotiperating with the bucket 31 to. be in raised position, while the cross-bar 37 coiiperating with the bucket 30 is in its lowermost position, and the receptacle 23 cooperating with the bucket 31 tobe in normal filling position, and the receptacle 23 cotiperating with the bucket 30 to be in discharging position, all

as represented in Fig. 1.

Assuming the parts of the apparatus to be in the relative positions illustrated in Fig. 1, operation of the hoistinganechanism hereinbefore referred to for operating the buckets will cause the bucket 30 to ascend and the bucket 31 to descend. Lowering of the bucket 31 causes it to bear down against the bar 37 below it, with the result of drawing down the cable 36, thereby turning the receptacle 23, coiiperating with the bucket 31, upon its journals, the movement of the bucket 31 downward while in engagement with its cross-bar 37 being sufficiently great to cause the receptacle 23 to be rotated through an arc of about 120 degrees, thereby causing its open side to register with the cotiperating outlet 22 of the respective chute 14, and

it being understood, as hereinbefore described, that a portion ofthe curved wall 35 of the receptacle 23 by reason of the foregoing operation is carried into registration with the outletll of the bin 7 for cutting off the discharge of material therethrough while the receptacle is discharging. -The apron 41, which is formed of a bottom-plate 12 and side-plates4c3 secured thereto and disposed beyond the chute sides 20, is counter-weighted as represented at 44, and in its normal position extends a'crossthe lower' open end of the chute l t, as represented in Fig. 1, for maintaining the outlet 22 of the chute closed. As soon ascoal begins to flow from the receptacle 23-into the portion 22 of the chute 14, the force of the coal exerted against the bottom 41-2 of the apron causes the latter to be turned,v on it s' hinge to the position illustrated of the one 'shown on the lefthand side of Fig. 1, it being-understood that the parts of the apparatus are so arranged as illustrated as not-to cause any coal to flow from the receptacle 23 against the chute 41 until the bucket,ewith which it cooperates, has traveled sufliciently far into thepit to extend below the outer end of the apron, and thusall the coal flowingfrom the chute 14: is dischargedinto the bucket cooperating therewith. Thus, hen' the receptacle 23 is turned todischa'rg pcsition by lowering of the bucket 31 as described, the parts of the loadingmechanism and chute-device coiipcratii'ig with the bucket 31 will assume the position represented in Fig. 1 or the corresponding apparatus operating in conjunction with the bucket 30. As soon as the bucket 31 is filled, the hoistingll'lCCllillllSln is reversed and the bucket 31 rises in filled condition and the bucket 30 descends empty. As the bucket 31 rises, it causes the chute -11 cooperating therewith to be moved to the position illustrated in the right-hand side of Fig. 1, the receptacle 23 rcn'iaining in discharging position until the bucket 30 in its descent lowers the crossbar 3T cooperating therewith and turns the receptacle 23 for discharging its contents into the bucket 30, during which movement the receptacle 23 coo 'ierating with the. bucket 31 is turned to filling position as illustrated in l? 1. ceptacles 23, under th action of the buckets 30 and 31 operating in opposite directions are caused to be :uitomatimlly operated to receive coal from the bin 7' and discharge it tl'u'ough their cooperating chutes 1 L into their respective buckets, and that the only operation performed by the buckets, in their rising movement, with respect to the loadermechanisms, is that of throwing the aprons :l-l to closed position. The manifest advantage of thus operating the apparatus is that of reducing the danger of injury to it as derangement or interlocking of the loaderincc anism is avoided.

By providing the hinged aprons 41, which operate as gates for the chutes It, and the curved sections 16 of the plates 15, any dust or small particles of coal which unavoidably leak from the hopper walls of its outlets and the curved walls 25 of the receptacles 23, when the latter are rocked upon their journals, is retained in the chutes 14 and is not discharged therefrom, excepting through the aprons 4:1 when the buckets are below them, and thus no dust or small particles of coal is discharged into the pit.

As certain features of my invention are applicable to apparatus in which but a single loading-mcchanism is provided instead of two as illustrated of the preferred construction, I have shown such features of my invention illustrated in connection with a single loading-mechanisin operating automatically by the rise and descent of a bucket cooperat ng therewith. This constructionis in all particulars the same that illus tratcd of the single loading mechanism and its operating means in Figs. 1 to 3, with the exception that in this modification the cables 36 and 4:0.and sheaves 34: and 35 are omitted and the receptacle 23 is connected with the apron ll through the medium of links 45,

It will thus be seen that the re 7 between the -single-clnunbcred receptacle of one only of which is shown, ivoted toward their upper ends to the hea s 24 of the receptacle as indicated at 4:6, and at their lower ends to the sides &3 of the chute 41 as indicated at 47, these links being connected with the cross-bars 37 by cables 48 and at all times inclining with relation to the vertical plane. By this arrangen'ient the turning of the loader mechanism to discharg ng position is effected by the lowering of the crossbar 3'7 under the action of the descending bucket cooperating therewith, and its movement to filling position is effected by the arranging of its cooperating chute to closed position when operated by the ascending bucket. It will also be understood that where a plurality of loading-mechanisms are employed, each may be equipped, if desired, with mechanism for turning the receptacles to normal filling position by the ascent of its cooperating bucket.

While I have illustrated and described the preferred form of my invention as embodied in an apparatus the hopper of which has discharge-openings in its opposed Walls for drawing the coal from opposite sides of the hopper, it will be understood that the discharge-opening may be on the same side of the hopper and that the receptaclemechanisms for discharging the coal into the buckets may be located side by side where such an arrangement is desired, with out departing from the spirit of my invention.
