VThis invention relates `to material'gathering mechanisms and more particularly to devices for loosening and gathering material to be handled bya loading machine.

One object oii the invention is to provide an improved loading mechanism for gathering loose material and vdelivering it to al in'ine car or the like. Another object of the inven# tion is to provide improved gatheringmecha? nism for* a loading machine. further object of the invention istofprovide animproved gathering mechanism ...which may operate in one relative positioning of itsparts to'loosenmaterial to be gathered, and in anotherrelative positioning of its partsto move the material to be gathered, towards and onto a conveyor. A still further object of the im vention is to provide gathering mechanism which is s o constructedand arranged that in theperformance ofeitherof'thestated Vfunctions its actuating and controlling mechanisms shallinterfere to a minimum/ degree with `the carrying ,on of the "operations, Other and morespecic objects y.ofthe invention will become apparent :in the course of the Vfollowing description ,and-:will be more the `front end of the partially inf vplan and partiallyiii-section,- of one sideof the gathering mechanism.v Y ,-1 Fig. 5 is a vviewsimilar to'F-ig. 1, showing the parts indifferent positions.

Y Y clutch 36, having'suitable controlmeans 37, is provided to coniiect'the shaft 1.6 to a sleeve 38Q A pinion 39 on sleeve 38 meshes withA a gear 40 coaxial with the shaftv27 land arranged to rotate a sprocket 41 ywhich is connected by a chain 42 with a transverse f shaft 43 jouinaled in forwardly extending portions 44 of the body of the loading machine. This shaft carries pinions 45 which engage-arcuate'racks 46 secured tothe arms 1l and 12 and thereby enables raising and lowering of the outer ends of thesefarms and .of thefgathering mechanism carried byV them.

As indicated' in Fig.` 4, the arms 11l and 12 [are hollow. Theyare connected together for simultaneous movement by V`a 'transverse 4 v brace member 50." Asthe construction of the arms' is the same, the arin- 12 onlyiwillbe described in'detail'; At its front end is rotatably mounted altransversely'extending shaft 5l carrying at the outside of the arm a crank' lplate 52. 'lhisplate vcarries a'crank pin 53. The shaft V51 within the' arm carries f a sprocket 54'which is connected by a chain 55 with a vsprocket A56 rotatably supported on 4a p shaft 57 nearer the pivot of the arm. A

sprocket 57 a is secured'tosprocket 56 and is actuated by the chain 571?, which the sprocket 278 oii theshaft 27 drives.v Each of the crank pins 53 carries .andimlparts movementcto support ,fmember- 58.

,Members 58 at their front ends" support ai transversely extending shaft'59, to which is suitably secured, as by welding, .abiiilt-up blade Y member 60 providedl with Vreplaceable teeth 61. Theshaft) is journaledin bear-vr ings 62' and-at one end, -pthatadjacent the arm 112,1it carries a sprocket 63 which con.- trols in part, with associated pai-ts, to be described, tlie nature `of 'thevr orb-ital `movement of the blade 60 and teeth 61 when the crank pin "53 moves the support members 58.

'stead of downwardly. .Y From what .has..been.ist`ated, the mode of to form parallel guide Surfaces which cooperate with a block 65 pivotally mounted upon an extension ofthe shaft member 5.7. It will be apparent that as the crank pins 53 rotate, the supports'58 Vwillmove longitudinally and thattheir rearward ends will be slidaby guided by the guide members 65. Accordingly,

the blade member 60 will be inovedin a closed orbit. v c i '1 0 modify the orbit of the blade member or digging device and make it appropriate, respectively, for breaking down standing coal .and for moving the coal yonto the shovel,

mechanism is provided cooperating with the sprocket 63 to impart to the shaft 59 anjoscil latin'g. movement yas well as an orbital move* ment. f Pivotally` connected 'co'aXially with the shaft 57 is a'swinging arm`70 having'- a latchmechanism 7lat its rear end'. This latch mechanism is adapted'to secure the arm V7.() in diierent angular relations to the arm 12 anda segmentdevice 72 with suitable l 'with-a chaindevicemade upof aplurality of roller lchain sections 8O and 81frespectively l cooperating witht'heI sprocket-63 and 78', and turn-buckle devices 82 and Y83 which connect the' exible Vportions Lof; the chain. The sprockets 63y and 78 l provide v'moment arms.

It will be evident, referring -to Fig. 5, thatv as the' arm 7 YO-isl swung from the fulll line posiL tion (theu'pperposition) toi the dotted line position ,-(low'erfposition),the arm v7G will be lswungV from'-4 a positionl in "the-1 fourth quadrant'clockwise to a position inthe firstA quad# Y rant (and accordingly the ,sprocket 78 Ewill move, through Vthe flexible connection 80, v81, '82, 83, the sprocket 631in aclockwise direction and so cause-the blade (30 and digging fingersilsto project sharply forwardlypinoperation willv belreadily;funderstood. Asfsuming that its-is desired to.y gather vmaterial onto the shovel, the sprockets28will bero'- tated in a counterclockwise'direction viewed fromtheyleftsidezof.the machine, land ac cordingly the crank discs52will'rotate in: aV

' counteiclockwise direction and cause thesup-v porting 'members 58139. move upwardly, forwardly, downwardly, rearwardly, andl again upwardly at their outer ends Aand accordin g1 ly-'the digging elementsIY 60,1' 61 will traverse Y -in a counterclockwise direction an .iorbityinl which theyrwil'l enter,fandfthen movetoward FTI the right, in Figs. 1 and: 5, the material which is to bemoved onto the shovel. Now it Will be observed that since, during this operation of parts, the arms are in the upper or full line position of Fig. 5, the blade GO and tooth elements 6l Will, in their lowest position, be substantially perpendicular to the bottom, and since thepinion 7 8 Will receive an oscil` lating movement as the support members 5S move forward, down, etc., through their orbits, it fill be clear that ,the digging elements Will pivot rearwardly during the retractive movement of the supports While tending to pivot forwardly during the for# Ward movements of the supports and thereby provide ay very desirable lioeing action.

Now, if the arm 70 is moved to the dotted line position, this Will cause the sprocket 79V to be moved a very substantial distance clockwise and then, With a reversal of the direction of rotation of the crank disc 52 and crank pin 53 produced by movement of the clutch member 29 into engagement with the gear element 3l, the digger devices will be caused to traverse their orbit in such a manner that there will be a tendency to dig` into a standing tace and shovel the material over the top of the digger teeth 61 and blade 60 and downward onto the shovel.

From the foregoing description it Will be evident that l have provided an improved mechanism for controlling the orbit-al movement of a digger device in which there is a complete elimination of all connections With the digger element except adjacent the extremity of the shaft which supports this element. Accordingly there are no links or the like to interfere with either the digging or the breaking-down operations and the entire u'idti'i of the digging mechanism is unobstructed. By providing points 90 as indicated upon the ends of the arms ll and l2 it is possible to secure a ramming action in addition to the digging act-ion which has been described.

While there is in this application specifi cally described one form which this invention may assume in practice, it will be understood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodied in various other forms Without departing from its spirit or the scope ofthe appended claims.
