CONVEYER APPARATUS.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed March 28, 1908. Serial No. 423,945.

To all 'whom it may concern:

Be it known that we, HENRY B. SAUEE- MAN and JOHN A. SAUERMAN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Conveyer Apparatus, of which the following is a specification.

The use for which our invention is more particularly adapted is that of elevating material such as coal, crushed stone, gravel, sand or other materials, from a receiving bin or boot to a storage bin and our primary object is to provide a simple construction of apparatus capable of performing the transferring operation quickly and positively.

Referring to the accompanying drawings- Figure 1 is a view in elevation of a receiving-boot, a storage-bin and elevating apparatus therefor constructed in accordance with our invention, the boot being shown inV section. In this figure the position of the bucket as it rests upon the material to be elevated is represented in full lines, and a position it assumes intermediate its lling and dumping is represented in dotted lines. Fig. 2 is an enlarged view in elevation of the bucket and its operating mechanism shown in Fig. 1. Fig. 3 is a view like that of Fig. 1 showing the bucket in the dumping position; and Fig. 4 is a view in elevation of a bucket showing another way of mounting it on its guides and another means for turning the bucket, this construction constituting a modification of that shown in the preceding figures.

In the construction illustrated in the drawings areceiving-boot is represented at 5. This boot, as shown, is divided into a receivingchamber 6 and a chute 7, by a depending wall 8 reaching short of the bottom of the boot to render the chamber 6 constantly open to the chute 7. The chamber 6 has a rounded portion 9 for the purpose hereinafter explained, and the chute 7 has an inclined bottom 10 for directing materialdumped into the chute from cars (not shown) which run upon tracks 11, into the chamber 6. The boot is located at one side of a storage-bin 12, on the wall 13 of which is a chute 14 communieating with its interior for receiving material elevated from the boot by bucket mechanism hereinafter described.

rIhe frame of the elevating apparatus com- 55 prises uprights 15 forming a rectangular structure surmounted at its up er end by a platform 16, with two opposed beams 17 extending longitudinally of the uprights 15 from the platform 16 to the bottom of the boot. The beams 17 are provided with opposed channels 13 which open toward each other as represented and form guide-ways for a purpose hereinafter explained.

The elevating bucket which is represented at 19 is of general scoop-shape with its opposite sides 20 having straight converging edgeportions 21 and 22 and a rounded portion 23, between which sides the inclosing wall 24 for joining the sides together extends. The wall thus presents a rounded portion 25 and two converging straight portions 26 and 27, one of which is cut away as represented in the drawings to afford an opening 23 and an open penetrating edge 29 for engaging width the material to be scooped in a manner hereinafter described. The bucket is pivote d at itsl sides to the lower ends of links disposed on opposite sides of the bucket and carrying at their lower ends rollers 31 which are confined in the guide-channels 18 to be movable up and down therein. The upper ends of the links 30 form bearings in which is j ournaled a shaft 32 carrying rollers 33 on its opposed ends slidably confined in the channels 18 above the rollers 31, the shaft being also provided intermediate its ends with a fixed drum 34. Chains 35 and 36 are secured at their 'upper ends to the shaft 32 on opposite sides of the drum 34 and normally extend about the rounded portion 25 of the bucket to their points of connection therewith at lugs 37 on the inner surfaces of its sides 20. A hauling cable 33 is connected with the drum 34 and is wound upon it as represented in Fig. 2 when the bucket is in its normal position as hereinafter explained, this cable extending upward to a sheave 39 over which it passes to the point of its connection with a power device (not shown) for operating it. A holding cable 40 connects at its extensions 41 with the upper ends of the links 3() as indicated at 42 and extends upward to a drum 43, upon which it is wound, fixed on a shaft 44 jo'urnaled in bearings 45 on the platform 16. The shaft also carries a drum 46 upon which is wound a cable 47 to the free end of which a counterweight 48 is connected for a purpose hereinafter explained. Fixed to the drum 43 is a larger drum 49 over which an ordinary fixed belt extends in. a Well knowniwayv for arrest ing the movement of the shaft 44 When the treadle 50 is depressed.

The normali position of the parts ofthe apparatus is that illustrated in Fig. 1'. in

Which the bucket rests at its open portion upon the bed Aof material, such as. coal X, to be scooped, the cable 38 is Wound upon the drum 34, the Weight 48 is in raised position', and the shaft 44 is freely rotated.

To operate the apparatus,l assuming it to be in normal position, the .cable 38 isV drawn' vupon thus causing it to= unwind from the drum 34- and in so doing rotate the' shaft 32 With the result of. causing the chains 35 and 36 to Wind upon thc'latter. By Winding the chains on the shaft as described, the bucket is caused to be turned in the direction indicated by the arrow in: Fig.v 1, the penetrating edge 29 of the bucket engaging with the material X and sinking. deeper and deeper into it as the' turning of the bucket continues. By the time the bucket has been turned to the inverted position as represented by dotted lines in Fig. 1, it will have penetrate'dl the material' sufficiently far to scoop up a full load, whereupon' the bucket may be raised to the desi-red height for dumping it by continuing to draw on the cable 38: As thebucket is raised by the cab-le 38, the cable 40 is caused to Wind up ony the drum 43 by the action of the weight 48 in unwinding the cable 47 from the drum 461,. the Weight being preferably heavy enough to prevent any slack being produced in the holding cable 40v during' the buck-et elevating operation, but too light toi raise the bucket andl theV parts movable' With it.

The dumping of the bucket is effected by depressing. the treadleV 50 to apply the` brake to the sha-ft and thus hold the cable' 40 against movement, and thereupon slacking the hauling cable' 38', with the result of permitting thev bucket to turn by gravity onits journals to the dumping position illustrated in Fig. 3. The bucket may then be lowered and caused: to returnv to its normal position by slacking both cables 38 and 40, the bucket by reason of its pivotal connection toE one side' of the center of gravity as represented in Fig. 3', causing it to automatically swing. to a' position in which it will lie upon the material as represented in Fig. 4.

It is manifest that when the cable 38 is slackened and the bucket turns on its j'ou'rnals, as described, to normal position the chains 35 and 36 Will unwind? from the shaft 32 and the cable 38 will Windi upon: the drum 34, and thus the cabler 38 and chains are automatically returned' to normalpositions in which they are' ready to be' again operated for scooping up another load in a man-ner hereinbefore described.

The combination of the boot With the rounded portion 9 and! the' scoopguided in its up' andi doWni movements, and constructed and arranged to be turned to inverted position- While in engagement With the material vin the boot is very desirable, as the scoop acting, at its penetrating edge against the curved bottom of the boot by successive operationsmay be caused to scoop up from the boot all the material dumped into it.

Furthermore, by provi-ding the construction as set forth no valves or gate between the chute and chamber 6 are required.

In the construction represented* in Fig. 4, the links 30,` shaft 32' and drum 3'4 are omitted, the bucketV 19? being journaled directly tov shafts 512, each carrying a roller52 movable the guideeway's 18. The chains 35 and 36 are also'- omitted, though thisis not necessary in this construction, and in their place a baill 53 formed of two arms 54 and a cross-bar 55, is substituted?. The bail ispivoted at the" endsof its arms 54 to stub-shafts 56 extending beyond the bucket-sides 18 to cause the bail to extend preferably from a point at one side ofthe center of gravity of the bucket to the opposite` side thereof and beyond the curved portionv 25 of the bucket, lugs 57 being. provided on the bucket-sides for engaging' with the upper edges of the arms 54,.for a purposeI hereinafter explained. When the shaft 32 and' drumi 34 are omitted, the haul-ing line 38l as attachedl directly' to the bail15'3 andthe holding-line 4'() is secured to the stub-shafts 511, orifthe drunr 34 only is omitted?,l the holdingfline 40 may be secured tof the shaft 32...

rlfhe operation of the' construction illus trate'd in Fig.v 4 is as follows; The bucket 19 is turned! to'A invert it While in engagement with the material X to be elevated, by pulling'on the line 38, which causes the arms 54 te engage With the'lu'gs` 57 and with the leverage thus obtained turn the bucket. The bucket israisedi tothe desired height by continuing: thev pull the cable 38, the bucket being guided in`l its upward. movement by the rollers 52. To dump the bucket the cable 40 isheldfast and the line 38is slackenedrtol permit the bucket to-be turned' by gravity'to the dumpingl position, as in the case of the construction oftlre preceding iigures. y

It is manifest that in place of the chains 35 and 36 of the constructionillustrated Fig. 1, a bail and' engaging lugs such as those rep'- resented'- at 532 and:` 517 in Fig.` 4 may be used?, and that in: the construction illustrated in Fig. 4 the' chains 35 and 3 6 as shown inv Fig. 1, may be usedplace ofthe bail 531.

It will? be notedf that by empl'oying'a guide such as that represented at 128 forguidfing'the bucket in its travel from the point from which the material ifs sco'opedup.` tothe place of discharge, the diire'etionyof movement of the bucket is positive', and thusthis character et construction presents vgreat advantages Where it is desi-red that material: be taken from a fixed location such as from the receiving-boot and discharged at another fixed location as, for example, the chute leading into the storage-bin.
