Guides' or Ways6fa`rra1iged 'ing =rails 7 being shownl @fthe-purpose; cThe carrier preferably compri-ses' ai: frani vmade up ofp'ar'ts 9*?, 9",-'etci,=and 'With' suitable' supportingwheels''i oritheir equivalent.y 'In *order to hereafter` more clearly 'explain vthe -system,=' I .havefadesigft -nated one-'iframe or. carriage as 9 fandlthe' other 'as 9', similarly for.. other similar parts: As-shown the' carriage-'is provll'ede guides* 12"' corresponding toE thelgii'i-d-esft ythe shaft 5 and arranged sothat'theyA ill is over 'the'isliaft Eachv frameialso latches 15. may be provided With resilientmembers 18 .arranged to normally retain the same in operative position. In the preferred construction the bucket is hoisted to the top of the shaft or to the higher level by means of a cable 24 Which also laterallydraws thel bucket and carriage when the bucket reaches 2G the top of the shaft. The cable 24 is secured tol the-bail 23 of the bucket and to a drum 25 driven by a suitable motor or, engine26 -or the equivalent, suitable pulleys 19 and 20 carried by the frame at points 25 21 and 22 and a pulley 27 carried by the structure beingy preferably provided to guide the same. the bottom of the shaft by means of a cable 50 orits equivalent which may be secured S0 directly to the drum 25 and controlled by therv'ersal of the drum or which may be arranged in a manner explained hereafter. Any suitable means may be employed to control the discharge of material from the bin 5 tothe bucket 8 a chute 28 provided with a shield 29 being shown for the purpose, the construction being such that when the bucket descends it pulls down the chute 2S discharging a bucketful into the bucket 4o the shield preventing more than a bucketful from :being discharged from the bin. Hoisting the bucket raises the chute 28 to be again filled the same remaining closed until the bucket again descends. As the drum 25 isrotated drawing cable 24 the bucket is hoisted until it reaches the position substantially as shown in Fig. 3 (this figure showing the carriage having started on its lateral movement). Thile over the shaft and until the bucket is entirely hoisted the carriageis held against movement by a suitable locking memberl 30 engaging the notch of the lcoperating locking part 31. Locking member 30 is pivotally secured to the frame 55,-as'at1533andyisfoprated by a'rod 34 pivotj ally securedlA thereto at 35, which rodl is .operated by thelever 36 provided With an extended end 39. The lever 36 is pivotally secured to the frame at 37 and to the `rod 34 at 38. A resilient member 341 is also pro- 'vided and arranged to resiliently retain the parts in operative position. When `the vbucket is raised until the bail 23raises the end 39, the catch 30 will be disengaged from 654 the notch of part 31. thereby releasing the The bucketmay be returned ,to'

carrier so that continued drawing of the cable 24 drawsthe carriage along the tracks 7. Any equivalent arrangement for locking the carriage over the shaft When the bucket is down maybe provided. The carrier is also provided With a suitablelever or lock 40 secured thereto as at 41 which is provided with a notch 42 adapted to engage the edge 421 of the bucket While carried laterally by the carriage' the arm 40 being re- 75 tained out of operative position by means of a stopV 32 carried by the structure when the carrier is over the' shaft.

To open the bucket at the desired time so that it lWill discharge its contents, I prelerably provide What'may be termed trips 44 carried by the structure and arranged to engage the latches on each side of the `bucket so that they will release the bottom and permit the same to drop. As shown the 3 5 trips are preferably secured to the structure as at 45 and provided with suitable stops 47. Normally the trip 44 is held against its stop bymeans of a weight 49 or its equivalent'arranged on the extended arm A48, a 9- roller 46 may also be arranged as shown if desired. -As the carriage 9 moves over the' shaft the trips 44 arranged Where desired engage the hooks 15 substantially as shown by the dotted lines (Fig. 3) releasing the 95 bucket bottom, the trip swinging about the center 45 on the return of the bucket permitting the hooks to pass. To close the bucket I'preferably provide a member 52 arranged Wherever desired, as shown substantially near the elevator shafhwhich will force the bottom up in position where it will again be engaged by the hooks 15. As shown the member 52' is pivotally carried by the structure as at 53, the same being provided with a stop 54, and. suitable means such as a Weight 521 for drawingthe same back into position. vA Wheel 55 may also be provided if desired. Any equivalent arrangement of bucket and controlling or operating mechanism for the bucket may be provided. Before the carrier or carriage 9 reaches the. v end of itstravel toward the shaft, the lever or bucket lock40 engages the stop 32 releasing the bucket so that the same is supported in the carriage bythe cable 24. When the carriage reaches the end of its travel the bucket descends, the carnage being locked in position over the shaft. It might be noted that during the hoisting of the 120 bucketA as well as during its'lateral movement ythe same is carried or supported by the carriage.

In the preferred construction I use two buckets and arrange the same so that as one bucket is hoisted the other Will be retrieved to the loading point, that is they work alternately. Referring to the diagrammatic view, Fig. 4,- 8 and 81 represent the two buckets andv 9 and 91 the 'two frames. The 13C noie cable 24 `secured to bucket 8 passes over the pulleys i9 and 2G, over pulley Q7 to the drum Q Where it may be given a number of turns` varound the drum and then extends over pulleys 271,201 and 19I being secured to bucket 5G and 'being provided where desired. ,As

is obvious thisl construction forms vsubstantially an endless cable made up of the cable "24 and cable 50.l As the bucket 8 is-drawn up by means of the cable 2e vthe hucketS1 y and the carriage 91 are drawn towardl the loading' point. Vhen the bucket 8 reaches riage is drawn along'the tracks until `the other bucket reaches the bottom of the shaft, the trips etal. foroperat-iiig the bucket being of course arranged in the travel of the carriage at the pointlvvhere it is `desired to discharge the load. It might lbe vnoted that 4the tracks over the shaft are slightly inclined in the preferred construction. `Then the carriage reaches the inclination'the tendency l is for the Weight of the car to'always carry it to the endof its travel. f f A Any suitable arrangement may be ein ployed'to control' the operation of the drum 25 orto're'verse the same when a bucket reaches the bottom of the shaft, a simple arrangement being shown diagrammatically in Figs. 1,2 and 4c, in Which the motor 26 driving the drum 25 is controlled by a suit-` able switch Soperated by a plurality of levers 59 and'tl1 or their equivalent arranged -in the path of the carriages. -These levers are suitably connected by means of cables 650-601 `or theirv equivalent -to the switch S, 'suitable pulleys 6l being provided if required. Operating the switch changes the polarity of the motor* thereby reversing the drum. Any equivalent arrangementmay be provided. as mentioned the arrangement' is suchthat the drum Will be 'autobottm-of the shaft andreceives its load.,

There may be any number yof storage bins andV of course it is obvious that the trips and binsmay be so arranged vthatone bucket Will be discharged in one bin While the other bucket may be discharged in any other bin.

Having thus described myv invention it is obvious that various immaterial modilicaltions may be-'made in the arrangement, construction and combination of parts shown and described or that the same maybe used Wherever it may be found applicable Without departing from the spirit of my invenL tion, hence I do not Wish to be understood as limiting myself to the exact construction, arrangement and combination of parts shown or described or uses mentioned.
