e i4 of Figql. Fig. 5 is'a, verticalthe scoop in side elevation 'andthe the mainframe of'jthe machine super ported on wheels a,- B an arm supporting ame mounted thereon embracing in its construction or associated with a horizon-' tally rotative turn-table; O a vertically swinging arm mounted. on ,the supporting frame; D a rotary scoop device carried by the free end of-the arm, and E a motor, likewise carried by the arm, for operating the scoop device.

F designates a conveyer belt supported on the arm for carrying material delivered thereto by the scoop device to the receiving end of a second conveyer belt G which di rects the material from the machine. As herein shown, said conveyer belt G extends beneath the machine and conveys the .ma, terial delivered thereto by the belt F to a point in rear of the machine. 7

Referring to the construction of the main frame, A A designate parallel side members,

thereof. Said side members, -as herein shown, assuming the form of I-beams arranged with their web portions in parallel vertical planes, and the transverse connecting members comprise tie-rods a extending through openings in the web portions of said I-beams and are surrounded by spacing tubes c which maintain the side members the proper distance apart. Said tie-rods are threaded at their ends and are provided with nuts a which serve ,to clamp the side members A, against said spacing tubes. In

addition to said tie-rods other transverse members A A A and A having the form of I-beams, span the side members and are arranged. with their bottom flanges resting upon and secured to the top flanges of said side members. Said cross-members A A A and A also serve as su orts for other parts of the machine and main frame are fixer to axles a which are journaled in boxes a bolted to the bottom .flanges ofethe I-beam frame members A Said wheels may rest and roll on track rails or may be constructed to roll directly on, the

ground, whereby the machine may be easily moved from place to place. 1 The arm supporting frame B comprises parallel vertical, laterally separatedplates B having the form of -1'.be ams,' which rise from and are secured to a horizontal plate; B which latter rests upon a platfOrn B l supported on the transversefmembers A main frame (Figs. 1- and 2). flhe' be hereinafter described. v The sup orting wheels a of theand A A transverse connecting members horizontal plate B and platform B constitute parts of a horizontally rotative turn table. For this purpose the slate B is provided with a central vertica pivot stud b which extends downwardly into and has rotative engagement with a vertical bearing sleeve 6 made integral with said platform.

The particular form of scoop bearing arm herein shown comprises a latticed girder, it embracing two laterally separated flat plates C C (Figs. 3 and 7) connected by transverse bars C C and reinforced at their upper and lower margins by angle bars 0 c. The arm is supported at a point near its rear end upon a horizontal shaft C fixed to the side members of said arm in any suitable manner and has hearing at its ends in pillow blocks 5 mounted upon the side plates of the arm supporting frame.

The pivot stud b of the turn table constitutes the vertical axis about which the scoop bearing arm swings horizontally, and the horizontal shaft C constitutes the axis about which said arm swings vertically. Thus the said arm is capable of movement through a wide vertical and horizontal range to present the scoop device at widely divergent angles to the pile or mass from which the material is being removed.

The scoop device herein shown rotates about an axis transverse to the arm C and comprises a plurality of symmetrically disposed scoops which are brought successively by rotation thereof into scooping contact with the pile or mass of the material being removed, each scoop being filled at one point in its rotation and dumping the contents thereof on the conveyor belt at another point in its rotation. Said scoop device is made as follows: D designates a cylinder or drum fixed to a shaft (Z which is journaled in bearing members (I d carried by the end of the scoop bearing arm C. To the periphery of said drum are ixed a plurality of plates or vanes (Z which extend outward therefrom in a direction tangential to a cylinder of slightly less radius than the drum. The outer margins of said blades are bent forward, with respect to the direction in which the scoop device rotates, to constitute the advance or cutting blades d of the scoops, the plates d constituting the bottoms of the scoops. D D designate laterally separated plates which are fixed to the ends of the drum and to the end margins of the $000 bottoms, and said plates constitute the sire walls of the scoops or buckets. marginally recessed in their parts adjacent to the cutting blades of the scoops, so as to give clearance to the cutting blades and thus facilitate the o )eration of the scoop in removing material from a pile or mass.v

The motor E, which may conveniently be an electric motor, is supported upon a shelf or bracket E which is fixed to the rear end Said side Wall plates are of the arm C. Its motor shaft is connected with and rotates a shaft 6, which latter carries at its outer end a worm E which meshes with a worm gear E fixed on a transverse shaft 6 which is journaled in the side plates C of the arm C. To one end of said shaft e is fixed a beveled gear e Which,meshes with a beveled gear (3 fixed to the rear end of a longitudinal shaft E journaled in bearing members fixed to the outer face of the adjacent side member of the arm. C. To the forward end of said longitudinal shaft E is fixed a beveled gear 6 which meshes with a beveled gear d on the adjacent end of the scoop shaft d. The gear connections described between the motor and scoop device are maintained in operative relation in all positions of the arm and the proportions of the gears are such as to constitute a speed reducing gear mechanism by which .the scoop device may be rotated at a suitably low speed.

Next referring to the mechanism shown for actuating the arm to swing it vertically about its horizontal axis, said parts are made as follows: H designates a worm gear segment which is fixed to one end of the horizontal pivot shaft C and depends therefrom. Said gear segment meshes with a horizontal worm H located below the level of the arm C and carried by a rotative shaft h which is journaled in bearing members h bolted to and rising from the horizontal plate B of the turn table. To the end of said worm shaft h is fixed a hand wheel 71 through the medium of which a worm is rotated and imparts through the gear segment H, vertical movement to said scoop carrying arm. I

' The mechanism shown for horizontally swinging the scoop bearing arm about its vertical axis is made as follows: I designates a beveled gearsegment that is bolted or otherwise fixed to the upper face of the upper member of the turn table. Meshing with said segment is a beveled pinion 1' carried by the forward end of a horizontally arranged, longitudinally extending shaft 1 which is journaled in bearing members i i rising from and su ported on the transverse members A A o the main wheeled frame. --The bearing member 2' is formed to provide also a bearing for a short vertical shaft I which carries at its lower end a beveled pinion i meshing with a beveled pinion if on the adjacent end of said horizontal shaft I. The vertical shaft I is provided at its upper end 120 with a hand wheel I by means of which the parts areoperated to effect the horizontal adjustment'of the scoop bearing arm. Y

The conveyer belt F which receives the material from the scoop device and deposits 125 the same upon. the conveyer belt G is trained about rollers F W, (Figs. 1 and 2) the shafts or trunnions of which are rotatively mounted in bearing members f f fixed to the side plates of the scoop bearing arm. The said conveyer belt F is thus carried-- by the sco'dp bearing arIn and beneath the same, and is maintained in the angular relation with re' .spect tosaid arm and scoop device in all posi- .-t1ons of the arm. The rearmost roller F constitutes the driving roller of said conveyer belt and is conveniently driven from the gear mechanism which connects the motor E with wthe'scoo'p device- The means for driving said conveyer belt F as herein shown is made as follows: F designates a shaft which is rotatively mounted in a bearing member f fixed to one side of the scoop bearing arm,

and is provided at its lower end with a gear f 'carried-bythe adjacent end of the shaft or trunnion of the roller beveled gearf which meshes with a beveled The upper end-of said shaft F carries a beveled gear f which meshes with a beveled gear f 8 carried by the adjacent end of the shaft e of the worm gear e t Plates F attached to the side members of the arm by bolts f are located at the sides of the conve er belt F to prevent the material falling off of said belt.

The forward end of the conveyer belt F "is located as closely to the scoop device as conditions will permit, as best shown in Fi s. 1,5 andb. The scoop device rotates-in t e direction indicated by the arrows in said last mentioned figures, and the construction of the scoop device is such that the contents of each scoop or bucket, as the said scoop turns rearwardly over the axis of rotation of said device, fallsupon the reverse side of the bottom of the scoop next in advance thereofand is guided by sald rearwardly inclined bottom to the receiving end. of the conveyer belt F. The bottom of each scoop and the-parts of the side plates D at the ends thereof thus constitute,in effect, a chutethrough which the material dumped from a scoopnext in rear thereof is directed to the conveyer belt thereby insuring a completedelivery of said contents to theconveyer.

The conveyer belt G which receives the material from the conveyer F andconveys said material away from the machine is herein shown as mounted between'the side members of the, wheeled frame A and is trained about front and rear rollers G G the shafts or trunnions of which-are rotatively mounted in bearing members 9 9 attached to the side members-of said frame. The upper lap of the conveyer belt Gis supportedat intervals -by idler rollers; G? which are rotatively mounted, as herein shown, on the spacing. tubes 0, of the transverse connecting mem ,bers of the wheeled frame. Said'rollers, as herein shown, have hearing at their ends only on said spacing tubes, as bestshown in Fig. 3,

the central parts of the rollers being free from contact with thespacin tubes. To thisend the rollersare provide flitl'theil' ends with hollow plugs gtwhich fit tightly in the end of the rollers and are formedywith bearingopenings of-a diameter to rotate frecly onftl'ie spacin tubes" The lower lap of the con-v veyer elt G is. likewise sup orted at intervals upon rollers 6 G two 0 which are journaled upon the axles ofthe wheels a and another or intermediate one of which is journaled in bearing members 9 fastened to the bottom flan es'of the side frame members A Horizontal ars Gr are arran ed longitudinally at the s'ides of theu per up of the conveyer belt to prevent the oose material from falling off the same, as best shown; in Fig.2,

and said bars are attached to the side members of the frame by. means of brackets g. The conveyer belt G isconvemently driven by a motor J,'which may be anelectric motor,

and which is mounted on the rear end 01' the machine frame, as shown in Fig. 1.. Said motor is operatively connected with the rear or, driving roller G of the conveyer belt G by means of a shaft 1' which carries at its up er end a beveled gear which meshes wit a beveled gear j on the motor shaft. The

shaftj carries at its lower end a beveled gear 7'? w llchmes'hes with a beveled gear 9" fixed to the shaft of the rear or driving roller of the conveyer belt. i

The loose material is delivered from the conveyer belt F to the lower'conveyer belt G through a hopper K supported on he-forwardend 0 the frame above said lower belt, said frame being extended a distanccfrom the turn-table to provide a support for said hop-- per. The hopper is provl the worm gear E or entirely over the hopper,

a guard L is providedin rear of said up er conveyer which extendsacross the space e- 'tween the side members of the scoop carry-- ing arm and is attached at its margins to said side members Said guard is carried down- .wardly to the level of the upper end of'the hopper, and the lowerportion'l of the guard may be made flexible. Atransverse conveyer M may bearranged beneath'the conveyer-G to receiveth'e material from the'latter conveyer and convey it laterally froin the machine. Said transverse conveyenma if desired, be arranged in front ofgthe machine frame to receive the material" directly from the conveyer F through the hopper-K:

It will be observed that3the'ii "o'sitioh of the motor on the scoopcarryingiarm is "sueh'with respect to the horizontal pivo-tlof said arm as to tend to counterbalance "the fre'endt bf the scribed may arm andsthe scoo carried thereby thus enabling said arm to be raised with the. exertion of comparatively little power.

The details of construction herein debe considerably varied Without departing 0111 the spirit of the invention and I do not wish to be limited to such de tails except as hereinafter made. the subject of specific claims.
