iippiieation inea May 1, i928; semi No. s741318.

This invention relatesto material lhandling structuresof that character wherein the material to be handled is discharged automatically shifting .the spout to Va dis. charge position when the vbucket,enters thev pit and automatically closing or raising lthe spout to a cut-,ofi7 positionv when the,bucket is hoisted from the pit.

The general object is to provide a spo-ut formed ina plurality of sections, certain of the sections being pivote'd and normally hel-d in a raised position, .and provide`r means actuated by the descent of the vbucket into the pit to shift the pivotedsections of the spout in av downwardly 'inclined 'position whereby the material shall be discharged into the upper end ofthe bucket, the spout being so constructed vas toV prevent the discharge of material until .the bucket has been fully lowered. e 'f A further object is to provide means actuated by the bucket itself when it is lifted from the pit acting tov positively lift the spout and shift the sections to a cut-off posi-tion.` y

` X `still fu-rtherobj-ect is to provider means normally supporting the `sect-ions vof the.

spout i-n a raised position, which means is Y adapted to be engaged by jirollers on the sides `of the lbucket and shifted downward by the descent of `the bucket into its fully lowered position in the pit, which lmeans is n provided with jaw-s with which the rollers onthe bucket lare adapted to engage, causing the positive and certain actuation ofthe spout-supporting means when the bucket lowered into the pit or rises therefrom, these` aws being so constructed as to prevent any possible jamming of therollers between the',l

guide rails of the pit upon which the rollers move, said aws doing away with the neces* sity of careful fitting ofthe various parts,`

Other objects haveto .do withthe details Vof construction and arrangement of parts VVas will appear more fully hereinafter.

`My 'invention is illustrated in the accompanying drawings, wherein Figure 1 is a vertical ing lowered;

y `Figure 2 is a like view to Figure 1, the

spout being raised;I

- Figure Sis a like view vto Figure l lbut Y showing the several sectionsy of the spoutv in Figure lis af detail view of sectional view. through a hopper showing my improved spout and bucket in elevation, the spout bethe outei end I of one oft-he liftingarins, the upper end of the lifting being broken away;

Figure 5 is alike yview to `vFigure 3 but showin-g the spout .in its fully raised and 'cut-off position; i'

Figure 6 is a sectionon theL line 6-6 of Figure; Y Figure 7 is a ysection on theline 7 7 of Figure 3;" v. e i Y Figure 8 is a front elevation of the cut-.off section. y

Referring to these drawings, l0 designates the hopper into which material, such 'as' coal, is discharged from railway cars. This hop-y per is `provided with the upwardly and for# wardly inclined front wall ll, though I do vnot wish lto be limi-ted to an upwardly inclined vfront wal-l,` having thereon .guides 12 anda gate 13, this gate being shown asbeing ladjustable byl means of a screw-threaded rod 14 which adjustably engaged with the gater andwliich is rotifitableby a crank or other suitabley means. This `rod `is supported in' collars carried abracket l5.

f.sectionthat is, .being provided with a bot tomand two sides but being open aty the top; The 'chiite' at its outer end is reinforced by a .transversefbar lShaving depending legs 19 riveted tothe walls Aof the chute. Mounted upon the inside walls l.ofthe chute inem;

adjacent l'the 'upper forward corner of the chute vand, disposed between the bearings QQ and vthe lower rear corner of the chute and `upon the outside faces Vthereof .are the end bearingsgQl for `theoperating. arms. Extending from the ybearings 2l are shafts 22 c'lisposed on each side of the chute 1.7

are the castings 23. 'llhese castings are arcuate on their lower faces and carry the inter- 'niedate spout section 24. The upper and inner corners of the castings 23 are formed to provide bearings 25a upon which these castings rock and the lower forward corner or each casting 23 is `formed with a bearing` 25 toi' the passage of a transversely extending stub shaft 26 constituting a pivot upon which the spout 27 is mounted. This spout 27 is also Ushaped in cross section and is reinforced at its rear margin by a lol-shaped bar 28, the legs ot this bar having openings 29 through which the shaft 26 passes. Thus .it will be seen that the spout 27 is pivoted to the section 23 and this in turn is pivoted to the section 17, the section 23 being pivoted at its upper rear corner to the section l7, while the spout is pivote-,d at its lower rear corner to the section 23. Y

lt will be seen that the intern'iediate section 24 with the spout section 27 forms, when the intermediate section and the spout section turn to the position shown in Figure 2, a cut-oil, the intermediate section 24 acting` to bridge the gap between the lower end ot the spout section 27 and the 'l'orwai'd end of the chute section 17 when the spout section 27 is f turned in the position shown in Figure 2.

Disposed on each side of the spout sections i7, 23 and 27 are the operating arms 30.

These arms at their rear ends are pivoted to the castings 2l and project beyond the forword end ot the spout 27. lach arm consists of a channel-iron having` a bearing bracket 3l attached to its rear end by which it is pivoted to the corresponding` casting- 2l.-

Riveted or otherwise attached to the middle ot' each arm 30 is a plate 32, this plate being` 'approximately triangular in form above the correspending!)a arm. `lxtending around the spout 27 is a yoke consisting of an upper cross beam shown as T-shaped in cross section, a low fr channel iron e4, and two pairs of channel irons 35 operatively engaged with the upper and lower beams 33 and 34. The channel irons of each pair are spaced apart, as shown in Figure 6.

rlhe arms with the plates 32 are disposed against the outside channel irons 35, the,

plates being riveted to these channel irons, and pivot members 3G extending' through suitable bearings in the irons 35 and in the arin 30 and engaging' with the vspout 27. 'lhus the yoke 37 formed ot the members 33, 34 and 35 is rigidly engaged with the operating` arms 30 and disposed at right angles thereto, and these operatingarms in turn pivotally engage with the bucket, the yoke. being ol such character as to give an abundance ot support to the pivots 36 upon which the spout 27 is mounted.

rlhis yoke 37 at its upper end supports a sheave 33 over which a cable 39 passes, this cable passing upward and over suitable sheaves 40 attached to a sheave support 4l, and the cable then extending down over a guidingsheave 42 to-a weight 43 which is of sutlieient weiolit to counterbalance the vsnout Y za l 7 the operating arms 30 and the yoke.

To the outer ends oli' the arms 30 are attached the spaced plates 44. These plates extend outward of the corresponding arm 30 and are riveted thereto so to form part tlineof, and between the lower projecting ends of the plates 44 is pivoted the lower jaw 45. The plates 44 are estenoed upward above the channel iron arm 30 and then ton wardly extended and these forwardly extending lugs 46 have pivoted between them the upper jaw 47 which confronts thejaw 45. This upper aw has a tail or extension 43 which extends upward and inward and through which passes the stop screw 49 adapted to bear against a separator 50 mounted between the plates 44. This will permit the jaw 47 to swing downwardly and `in- 'wardly but prevents. itV swinging upward, as

clearly shown in Figure 4. Disposed within the pit A opposite the lower portion ot' the hopper and opposite the H spout are the upwardly and laterally inclined rails 5l. rlhe bucket- 52 (which bucket is :tully described and illustrated in my pending application forv patent, Serial #275,477 liled ,r

on the .fifth day of May, 1923) is provided on its sides lwith the outwardly projecting rollers 53. The bucket is sup-v ported by a sheave 54 and cable 55: The

`bucket isopen at its top upon one side, as

at 56, and it is into this open portion oit the top of the bucket that the spout 27 discharges when the bucket and theV spout are both lowered. to the proper position.

1When the bucket is lowered into'the pit, therollers will strike the downwardly inclined rails 51 and then as the bucket lowers the rollers'will bear against the lower portions et the pivoted jaws 47, forcing; the lower portions inward vand permitting 'the rollers 'to move downward upon the rails 5l until they strike the lower jaws These lower Jaws 45 can swing outward to a position against the rails so that there is no posa L 4.

sible chance lor the rollers to escapepaslJ tl e lower jaws 45 and the rollers must ei age these lowerl jaws so that as the bucketconlinues to lower, these rollers bearing,` ar the lower gaws 45 will 'force the opel ngi' arnis downward. ri'Chis, through the pivots 36, will act to turn the sectioi'is 27 and 23 downward trom the position shown in ll`igure 2 to a position where the cut-ol^l section and the spout section 27 are both in align lll() lll) Vhen the bucket is yfilled and vis drawn upward, the yrollers 53 `inoye up therails 52 andV in doing so kstrike the iaws rllliese jaws cannot turn inward because 05E -the stop screws on the jaws and .hence therollers must under these circumstances liftthe arms 30 from the position shown' in Figure l to that shown in Figure 2. This turns the spout section 27 upon its pivot 26 and turns the cut-off section 23 upon its pivot 22 until the spout 'has arrived at the position` shown in Figure 2. At this time-fthe arms 30 have moved up so high that the rollers 53 can escape from the jaws 47 a-nd thek bucket moves upward, leaving the spout in its raised position whe-re it remains untilv the` bucket is again lowered. lhen thespout is lifted,

f the cut-eif'sectien and the inclination of the spout 27 prevent all discharge of coal or other material until the spout Vis again lowered.

Itwill he seen whereby ,the bucket is emptied form the subject-matter of separate .applications for patentstiled of even date herewith.

Vfhile have illustrated a structure ofv ythis character which vhas 'been found to Vbe particularly etlieetive Vand in which .the details have all been designed it'o securefthe end desired, l do not wish to be limi-ted to these details as it is obvious thft theyy rmight be varied in many ways without departing from the spirit of the invention. 1
