. To all whom it 'may concern:

Be it known that I, ROBERT A. OGLE, av

' /citizen oi" the United States, residing at Chicagohin the county oi' Cook and .State of` Iliinois, have invented a new and usefulA improvement in Loaders, ofj which the following is a speciilcation.

My invention relates more particularly to apparatus for elevating' coal iroin a hopper to a receptacle. to be loaded, as for instance a bin from which a supply of coal is furnished to a locomotive tender.

In cooling stations the hopper or chute for receiving the coal is preferably positioned below the level of the ground, that the tracks, on which the train from which the hopper is supplied, need not be elevated. The location of the hopper below the ground necessipermitting the lowering of a traveling bucket to a sufficient distance to allow coal discharged i'roin the hopper to fill the bucket. In t e construction hitherto provided the bucket was lled directly from the hopper, the coal being allowed to iow from the hopper into the bucket by operating a gatevalvev with which the hopper is equip ed. A serious disadvantage arisinl from t ese constructions is that the disc arge-end of the hopper and the bucket, when the latter was in position for filling at the bottom of the pit, werein darkness with the result that the operator in operating the valve of the hlper would often-not allow the coal to run ciently long to fill the bucket necessitat- V ing the rcloweringof the latter withloss of time, or the elevating of a short load; or on the other band would be allowed to run too long causing the bucket to run over and depositing coal in the pit with the result of necessitating the difficult work of removing the s )illed coal from the relatively deep pit. knot er great objection to constructions as hitherto provided is that 4in the use 'of the manually-o v erated valve used 'they are a )t to become c ogged by the coal with the resu t of causing the pit to fill and if the bucket is 'in the pit at the time, burying it.

My primary obfe'ct is to overcome the` objections to constructions oi this character as hitherto provided; and to roduce av construction whereby the coal will be discharged from the hopper iirst with a loader andthen into the bucket or other receptacle.

Referring to the accompanying drawings: Figurel is a view in elevation of coaling apas indicated at 22, to ena Patented @rime s, '1909.

paratus constructed in accordance with my invention, the storage-bin and pit-wall being shown in sectional elevation, this view illustrating the loader- )roper in its normal position, in which it fills, and the bucket in one of the iositions it assumes intermediate the ends o its travel. Fig. 2' isv a View like that of Fig. 1 showing the position the parts as suine when the bucket reaches its lowermost position in the pit and the loader is operated to discharge its contents into. the bucket.

. Fig. 3 is a view in front elevation of the apparatus of the preceding vfigures, the view representing the parts in the positions shown in Fig. 1. Fig. 4 is a view in sectional elevation of the loader and its aron mechanism; and Fig. 5, a section ta en at the of the arrow.

The lower discharge-end pol'tioii of a hopl per for coal or the like, is represented at 6,

this hop er being preferably arranged belowy lthe leve of a railway-track (not shown) to permit the coal, or otherrnaterial, to be dumped into the hopper directly from cars on the track. The hopper is so constructed as to afford as ace 7 immediately below the lower ends of tue conveying -l'oo'rsS and 9` with a cross-timber 1() extending entirely' across this s ace. This space 7, opens into the pit in w ich the bucket 1], hereinafter described, is operated. Located between the s ace 7 and the pit are vertical uprights 12 a jacent and secured to a wall 13 of the hopper `6. The bucket 11 for receiving coal line 5 on Fig. 1, and viewed in the direction tates the provision of a pit adjacent to it, for

from the hopper and elevatimlr it to the sur face to dump it into a rece taclle for. receiving it, has rollers 13L on its si es which operate in vertical guides 14 for guiding the'bucket in its movements, the bucket shown being of the ordinary form with an open top. The lower end-portion of the floor-section 9 is cut away to form an outlet linlwhich a chute- 'section 16 havin curved outer edges 'as indicated, aty 17 is ocated. p l

Loading lmechanism for receivin a predetermined aniountof coal is locate intermediate the outlet 1.6 and bucket. The loader is in the form of a semi-cylindrical receptacle 18 having a iiat bottom 19, sides 20 andan inclosing wall 21. The receptacle is pivoted at its opposite sides at points equidistant between its ends to the o osed `uprights 12, Eb e the receptacle to be rocked endwise. The wall 21 contains an Vopening 23 from side to side 'tiepw sition of the receptacle as represented Ain Fig. l registers with the outletl iti from the hopper and` in the position represented in Fig. is out of registration wit i it. 'l`he wall il also contains a discharge opening 24 and supported on the receptacle adjacent to this closes the receptacle has hlled und has been swung to discharge position, "the swinging olt the receptacle also operates to raise thc gate ISI. the slack in the fable H5 being sufficient io cause the gate to be raised to eoinplctelj. uncover the outlet 2li by ilutiine-tlie receptacle has swung to diwliarge position, thiI ell'ect ol' running` ih'l cable it". over the puliej.' ilo. as described, i' turing the gate. when it .starts to rise. to .suore twice as fastas the receptacle lb. and lhi` the Inte need not be constructed so as lo star! to rise until the receptacle has snuiuz to nithin u slioit distance of its lon'erinofa position. .\.s the receptacle swings. don'nn'ard at iis di`H outlet lo -cliarge-end the links 23S are caused to lili downward at their upper ends illus rausiugr at their inner ends on the rods 33 and united at their outer ends by a curved plate 1'34 which is so located and is of such a size as to ada )t it to completely close the opening .24 in tlhe receptacle-when the loader is in the position hereinafter described. The gate is connected to the lower end of arable 35 which extends over a pulley 3o and connects l trated in iig.

at its opposite end to a hook 37 on the 2 loader-wall 21, a weight 37 being secured to the cable between the hook 3f '1 and pulley-16.

'l he raising of the gate-valve 31 periniis the coal to freely dump from the receptacle 1S into the bucket 11, which thus hlled. is raised in any suitable manner. .1s thtl biuket 11 rises a roller '16 thereon engages with the and . tilts the receptacle 1H. backward toward its rl`lie normal position yof the receptacle 1S is j that illustrate( in Fig. l in which it extends l hopper, its gate 31 closed, andthe apron 2:) withdrawn, by reason'et its connection at its t rod 26 with the links 3S fastened to the opposite ends of a rod 39 journaled in brackets i 40 on the uprights 12, levers 11 being secured to the inks 38 and carrying adjustable f weights 42, whereby the tendency of the weights is to tilt the rods 3S upward and withdraw the apron.

bucket 11, this function beingaccomplished normal position, the opening being so located, as described, as to cause coal to begin to llow into the receptacle. 1S as soon as it. has been moved a slight distance, the coal thus falling upon the bottom of the receptacle to the left of the. center of gravity in r ig.

; 2, causing the receptacle to quickly complete its movement to 'normal position in which it rents at its rear end on the cross-beam il). T he swinging of the receptacle to normal po sition causes the gate 31 to close, the weight IS7 merely being heavy enough to cause the ln the uorinal position 'of the receptacle 18 as .described the coal with the bucket. 11. Y iacle to normal position also causes the liu automatically by two rods 43 pivoted near their upper ends to the sides of the receptacle 1S and at their lower ends connected with a cross-bar 44 which is caused to extend into the path of the bucket 11 by confinement between the meinbers of the bucket-guides 14. Thus as the bucket nears the limit of its descent it en gages with the bar 44, drawing down the rods 43, and thereby tilting the receptacle to i the position illustrated in Fig. 2. i the receptacle swings on its pivots, the coal discharged into it while in normal position, llows toward its outer end and the reniainiiig unfilled. space in the. receptacle is Ylilled by the continued flow of coal 1n. to it so long' as the outlet 16 remains open. By the time the slack in the cable 35 to extend between ilul pulley 3b and the hook 37a, and thus the cable 35 is prevented from becoming tangled The tilting of the recep- XS 3S to beA rocked to the position indicated in Fig'. 1, thereby moving the apron 25 to a pt sition in which it does not extend into the path of the bucket 11. The provision of the weight 42 serves to assist in turning the receptacle from its dum ing position to norinal, filling position an also aids in overcoming the great weight. on the outer end of the receptatle when turning te dumping position,

To avoid )ossible damage tothe loadermechanism should it extend in .discharging position when the bucket is moving donn-- ward, l slot the sides of the apron, as indicated at 47, and thus the apron will be caused to yield downwardly atI its outer end when so engaged by the bucket and the latter ina)- move to its lowermost position without doing anv daina'e. 1

, n lo avoid the leakage of coal, espeeialiythe lift) iineparticles or smalllumps thereof from the and the outlet 16 falls 'upon the lip and passes into the receptacle 18.

By thus provmmg the loader intermediate the hopper and bucket, it is impossible 'to open the bin to cause it to discharge its con--z tents into lthe pit, as described of previous constructions; and it is also impossible to overload or' underload a bucket.

inventionisthat of enabling the buckets to be rapidly filled, vas the operator is not'called upon to use. hi-s discretion in filling the buckets as in the manner described of prior construction, the operation of my improved mechanism being entirely automatic. 'Furthermore as the loader receives a predetermined amount of coal, its discharge 24 may be made considerably larger than the outlet of hop ercould practically be in constructions as liitherto provided, and thus the bucket may be loaded very quickly.

By cci'istructing apparatus of the'character set forth in accor ance with my invention, thi.,` material to be transferred resting normali)y inthe loader after filling, is caused to shift in the loader as soon as the latter begins to tilt and roduces a movement of the material throng the bin-outlet during the operation of moving the loader from normal t-o vdumping position, and thus the portion 21 of the receptacle, acting as an undercut gate, readily moves through the iowing material, thereby avoiding danger of obstruction to the movement of the Iioaderby lodgment-of the material betweenthc portion 21 and the bin-outlet.

W'liile 1 have illustrated and described my invention as applied to a coaling station, I do not intend to limit it to its use in this connection but desire to protect itin its a plication to .any system to which it may lfie applicable involving ythe transferring of mai terial from a hopper, bin, or the like, to con-v veyer rece tacles.

While means for controlli-ng Vthe supply to the loader as a part of the latter, namely its'wall 21, l'. do not wish to-be understood as limiting,- my invention to `such means as so far as cerfl tain ofv its features are concerned, any other means for controlling the supply to the loader may be employed. l
