BARTON s. SNOW, OF BATAVIA, ILLINOIS, AssIGNOR To fr. W. sNOW CONSTRUCTION OO., or CHICAGO. ILLINOIS, A CORPORATION OF ILLINOIS.

IKEATER-IAL-EL-EVATING APPARATUS.

Application. filed March 31, 1922. Serial No. 548,365.

To all whom t may concern.'

Be it known that I, BARTON S. SNOW, a citizen of the United States, residing at Batavia, in the county of Kane and State o-f Illinois, have invented a new and useful Improvement in Material-Elevating Apparatus, of which the following is a specification.

My invention relates to appara-tus of the general type commonly used for elevating io material such as, for example, coal from a hopper into which the material is dumped 'from railway cars located on tracks above the hopper, into a storage bin above the tracks from which the material is permitted to discharge as, for example, into the tenders of locomotives, this type of apparatus comprising a` vertically-operating bucket, or skip, for elevating the material into the uppermost hopper and power-operated cable means for operating the bucket, connected with the bucket and with a counterweight for the bucket.

One of my objects is to provide improvements in apparatus of the type referred to whereby the bucket may be elevated substantially to dumping position at a relatively high speed and the desired deceleration of the bucket at the end of its elevating movement accomplished without undue expenditure of power; another object is to provide a. construction of apparatus whereby a shallower pit for receiving the bucket when in loading position, may be provided, than in the case of prior structures', thereby greatly reducing the expense ofvforming the pit and greatly reducing the danger of encountering wa-ter in digging the pit; Another object of my invention is to provide for the automatic filling of the bucket, elevating'it and dumping its contents into the uppermost hopper, and thereafter lowering the bucket and repeating the operation stated, all in anl automatic manner. Another object is to provide in conjunction with the lower hopper, a charge-receiving receptacle for the purpose of receiving the charge from the hopper. lifting this charge above the outlet of the hopper and dumping the charge into the bucket in lowered position and before the bucket, after it has been raised and dumped, has returned to lowered position, returned to a position vfor receiving the charge and again elevatedfor dumping the discharge into the bucket iii lowered position, these operations being automatic, and.

the cliarge-receiving receptacle being elevated by the action of the counterweight for the bucket as distinguished from separate hoisting mechanism requiring power. Another object is to provide an apparatus of tlie character above stated'which will be positive, simple and economical of operation and be -better suited for performing the functions 'for which it is provided.

Referring to the accompanying drawings: Figure l is a view in vertical elevation of a railway coaling station equipped with my improvements, certain of the parts shown being represented in elevation, this view showing the bucket in lowermost, loading, position and the parts associated therewith in the positions they assume in this position of the bucket. VFigure 2 is a view in end elevation of the structure shown in Fig. l, certain parts of the structure being shown in section, the apparatus being viewed from the right hand side of Fig. l. Figure 3 is an enlarged elevational view of the lower part of the structure shown in Figs. l and 2, with certain parts sectioned, this view showing, by full lines, the position occupiedl by the parts cooperating with the bucket when the bucket is rising but before it reaches dumping position, and by dotted lines the positions assumed by these parts when the bucket is in either loading or dumping position, the bucket being shown in loading position by dotted lines. This view is taken at the line 3-3 on Fig. l and viewed in the direction of the arrows. Figurel is a section taken at the line 4 4 on Fig. 3 and viewed in the'direotion of the arrows. Figure 5 is a section taken at the line 5-5 on Fig. 3 and vie-wed in the direction of the arrows.

Figure 6 is a sectional view of the lower' hopper, the charge-receiving receptacle, a gate device for the hopper, portions of the hopper and the charge-receiving receptacle being broken away; and Figure 7, a broken section taken at the line 77 on Fig. 6 and viewed iii the direction of the arrows.

The apparatus shown comprises a pit structure which extends below the level at which the tracks, represented at 11, and on which the cars containing the material to be elevated are run, extend, thispit containing a hopper l2 open at its upper end and across which the tracks 1l extend, this hopper being provided for receiving the material from the carst Rising from the ground adioo jacent the pit 10 is frame superstructure 13 on which is mounted a hopper 14 shown as provided at its outlet 15 with spout and valve mechanism represented at 16 for controlling the dow of material trom the hopper 14 into the receptacle to be charged therewith, as for example a tender which will be located on the track 17. The hopper 14 and the control mechanism therefore may be ot any suitable construction, and as this part of the apparatus is of common construction, detail description thereoi is unnecessary. The framework 13 at the side of the hopper 14 opposite that at which the device 13 entends projects upwardly above the hopper which latter communicates with an inlet chute 13, and provides the support and guiding means tor a vertically movable bucket, or skip, represented at 19 and provided tor the purpose of elevating material from the hopper 12 to a position in which it discharges into the bin 14 through the inlet chute 18. The last-referred-to portion of the framework 13 is provided at opposite sides of the chute 18 with pairs ot vertical bars 2O spaced apa-rt to provide guides for the bucket 19. The bucket 19 is ot' a construction commonly provided in apparatus ot this general type, this bucket being provided with a bail 22 pivotally connected at its lower end with the underside or" the bucket. The bail shown is formed of the upper cross-bars 23, the lower cross-bar 24 which extends beneath the bucket 19 and with which the bucket is pivotally connected, and side bars 25 connected with the end portions ot the cross-bars and 24, these cross-bars at their extremities being provided with rollers 2G and 27 which extend into the vertical guideways 20, 'for guidance. The bucket, as shown, is of such construction that it is overbalanced tending to tilt on the cross-bar 24 of the bail, to the lett in Fig. 1 when in loaded condition. rlhe bucket is provided at opposite sides with laterallyextending rollers 23 which bear, under the tilting action of the bucket, against the adjacent vertical guide surfaces 29 ot guide bars 30 carried by the framework 13, the upper extremities oi these guide bars being curved toward the hopper 14, as represented at 31, and terminating' in the sulostantially7 horizontal portions 32, whereby when the bucket 19 is elevated to its extreme upper position, it will automatically tilt to the lett in Fig. 1 at its pivotal connection with the bail 22 and discharge its contents into the chute 13, and in the lowering of the bucket will be automatically rocked to upright condition.

The cable which controls the vertical movement oft the bucket 19 is represented at 33, ythis cable being connected at one end with the upper end ot the bail as represented at 34. The cable extends upwardly from the bail and around a supporting sheave 35 journaled on the framework 13, and thence extends downwardly to a drum 36 upon which it is' wound, the drum 36 being a hoisting drum operated from any suitable source of power, as from the engine represented at 37. rlhe cable 33 thence passes over a pulley 33 journaled on the framework 13 and thence around pulleys 39 and 40 constituting a block-and-tackle, the pulley 40 being journaled on the framework 13 and the pulley journaled in the upwardly-extending spaced arms 41 of the counterweight 42, the end ot the cable 33 opposite the end connected with the bucket 19, as stated, being connected with the framework 13 as represented at 43. The counterweight 42 is vertically movable, it being guided in this movement in any suitable way, as for ef;- ample by means oi" the T bars 432L supported on the framework 13 at opposite edges ot the counterweight and extending at portions there-ot into vertical grooves 44 contained in opposite edges ot the counterweight 42.

1t will be understood from the foregoing description that the arrangement ot the bucket, counterweight and the cable mechanism coiinecting these parts, is such that the coui'iterweight required for producing the counterweighting function, viz, to substantially counterweight the bucket plus one-haltl Jl L A( J .Ll L ine weight or the inatei ial which constitutes charge tor the bucket, is very much greater than in those cases, `as is the common practice, where the counterweight is so connected with the bucket, through the cable mecha-- nism` that. it travels at the same speed as the bucket, the purpose of providing a relatively heavy counterweight being hereinafter eX- plained.

Cooperating with the hopper 12, the outlet ot which is represented at 45, is mechanism for receiving a charge from this hopper, elevating the charge and there-after dumping it into the bucket 19 when the laitter is in the position shown in Fig. 1',y a description or this mechanism being as follows: The mechanism referred to comprises the charge-receiving receptacle 46 shown as provided at opposite sides with rollers at which this receptacle is rollingly supported upon inclined guideways 48 between which the receptacle 46 is locate-d. The upper end of the receptacle 46 is open and presents the inclined portion 49 which is spaced from. and arranged substantially parallel with.r the adjacent inclined wall 5() of the hopper 12 and in which wall the outlet 45 is located. the lower end oi the inclined portion 49 being formed with a cover plate 51 having` an outwardly-turned lip 52 which extends closely adjacent the lower edges of the wall of v'the outlet 45. The lower end ot the receptacle 46 is provided with a trough-shaped apron formed ot the side walls 54 located,

llo

at opposite sides of the receptacle 46, and a front connecting plate 55, this apron being located at the outlet 57 of the receptacle 46 and serving to control the discharge from the la-tter of the material charged into it. The apron 53 is pivotally supported on the receptacle 46 as indicated at 58 and in the full line position shown in Fig. 3 maintains thel outlet of the receptacle in closed condition, the apron being prefer-ably so weighted that the force exerted against it by the material in the receptacle 46 will not swing it to open condition. The apron 53 is also provided with an arm 59 which, in the full line position of the apron 53 in Fig. 3, extends substantially horizontally in a direction toward the bucket 19. The receptacle 46 is 1 connected by means of pivoting links 6G, with the lower ends of cables 61 which pass over pulleys 62 journaled on the frame of the structure, the other depending ends of the-se cables being connected with the ends of a cross-bar 63 guidingly confined at its ends in upright guides 64 stationarily secured in the pit 10. The parts of the structure just described are so constructed and arranged that when the receptacle 46 is in lowerinost position, the posit-ion shown by full lines in Fig. 3, the cross-bar 63 occupies the full line position shown in Fig. 3, in which it extends into the path of movement of the counterweight 42 in moving downwardly, the counterweight 42 being of such weight that as it descends in contact with the cross-bar 63 it will draw the receptacle 46 vupwardly along the inclined guideway 48 to the dotted position represented in Fig. 3 in which position the receptacle 46 becomes automatically locked, by the interlocking of latches 65 pivoted on the framework of rthe apparatus, with keepers 66 connected with the opposite sides of the receptacle 46, the latches 65 normally extending into the path of movement of the keepers 66 and being automatically operable, to permit these latches fto interlock with the keepers upon moving the receptacle 46 to the position just referred to. The latch devices 65 cooperate with trip levers 67 pivoted on the frame of the apparatus and superposing at ends thereof ythe adjacent ends of the latches 65, their other ends extending' into the path of movement of the adjacent upper corners of the bucket 19 whereby the bucket in ascending operates the latches 65 to a position in which 'they ydisengage from the keepers 66.

The receptacle 46, constructed, as hereinbefore described, operates in its movement from full line position in Fig. 3 to the dotted line' position represented therein, to cut through the material at the outlet 45, and in order th'atthis outlet shall be closed except whenV the .receptacle 46 is being charged with m'ateriahlprovidei a slide valve, represented at 68, Ythis valve having a plate-like portion 69 located below the outlet 45l and paralleling the latter and provided at opposite edges with brackets 70 carrying rollers 71 which rollingly engage the lower ilanges 72 of channel bars 73 secured to the hopper 12 to extend at opposite sides of the outlet 45, as more clearly represented in Fig. 7. rThe valve 69 is shown as reenforced at its lower edge by an angle bar 74, and above this bar is provided with Aan angle-shapedv stop-bar 75. The valve 68 is connected at opposite edges thereof, as indicated at-76, with the lower-ends of'cables 77 which extend @ver pulleys 78 and 7 9 journaled on the wall portion 50 of the hopper 12, the lower ends of these cables being connected with a weight 8O of such weight that it will positively draw the valve 68 upwardly, causing it to follow the movement of the receptacle 46 in traveling up the guideway 48, to a position. where this valve completely vcloses the outlet 45.

In the arrangement shown stops 81 are pro-A vided on the guide members 73 in position to be engaged by the lower-most ones of the brackets 70. J

A description of the operationof the ap'- Vparatus is as follows: Assuming the parts of the apparatus to be in a position in which the charge-receiving receptacle 46is in lowermost position, as represented in Fig. 3, in which position it is in communication with the outlet ofthe hopper 12 and thus receives a charge of material therefrom, the apron 53 of the receptacle 46 being in the full line position represented in Fig. 3, the bucket 19 in the position of the receptacle 46, as stated, will be ascending and will extend above the dotted position of the receptacle 46 in Fig. 3. As the bucket 19- continues its upward movement toward dumping position, the bucket upon reaching the upper end of the guide-bar 30, automatically dumping the charge previously introduced therein, into `ing the movement of the receptacle 46 and serving to close the outlet 45. Following the dumping of the contents of the bucket 19 into the vchute 18, the bucket descends and the counterweight 42 rises, the receptacle 46 remaining in elevated position. AsLk the bucket 19 nears the limit of its descent, it strikes the arm 59 of the apron 153, with the result of rotating the apron to the detted position represented in Fig. 3, in which position the apron overlaps the adjacent upper edge of the bucket 19 and serves as a chute through which the material discharges trom the receptacle 46 into the bucket 19 as shown by dotted lines in Fig. 3. lWhen the bucket 19 is operated to hoist it to dumping position, the bucket, by engaging with the apron 53 as stated lirst swings the latter in counter-clockwise direction in Fig. 3 to a position in which it is overbalanced on its pivot 58, whereupon the apron assumes the tull line position relative to the receptacle 4e as shown by full lines in Fig. 3 in which the outlet of the receptacle is closed. es the bucket 19 continues upwardly its upper edge engages the levers 5'? with the result oi rocking the catches in clockwise direction Fig. 3 to a position in which they disengage from the keepers 66, whereupon the receptacle 46 is tree to run down the inclined support 48 to the full line position. represented lin Fig. 3. Any suitable means tor stepping the receptacle 46 in {the lowered position stated may be provided, as fior example the stop blocks 82 shown as secured to the inclined support 48 in a position to be engaged by the lowermost set ot rollers 47.

1t will be understood trom the foregoing that the movement o the receptacle 4S from lower, filling, position to upper, discharging, position is eiiected by the torce exerted by the counterweight 42 in lowering, it being possible, by providing the block-andtackle mechanism hereinbefore described, to provide this counterweiglit of suifiqicient weight to actuate the receptacle 46 as stated, without erzerting an undue amount of lifting force on the bucket 19, it being desirable that the counter-weight 42 substantially counterbalance only the weight oi the bucket and one-halt the load carried by the bucket.

Furthermore the provision of the receptacle 46 movable from a lower filling, to a higher discharging, position, is ot advantage as the pit into which the bucket lowers may be very much more shallow than where a chute for delivering materia :trom the hopper 12 to the bucket, and not having the bodily movement as stated ot the receptacle 46, is provided.

rllhe apparatus provided in accordance with my invention is not only oit comparatively simple construction and positive in operation, but is automatically operable in the various ways stated, with the expenditure of the minimum power.

The arrangement or' the various parts is such, as shown, that the counterweight 42 does not engage the cross-bar 63 until the bucket nears the point at which it discharges, and as the weight presented. by the charged receptacle is relatively great, the

bucket is automatically slowed down before it reaches the discharge position.. Thus the bucket may be raised at relatively high speed and the `speed of its movement is automatically reduced to the desired degree before it reaches dumping position. Furthermore the counterweiglit being compounded as explained, by the block and tackle, it moves relatively slowly, while the bucket moves rapidly, and thus it acts upon the charging receptacle, to raise the latter, at a slow and positive speed.

li/"illiile l have illustrated and described a particular' construction embodying my iiivention, l do not wish to be understood as intending to limit it thereto as the saine may be variously modiiied and altered without departing 'from the spirit ot invention.
