Application September 29, 1941, Serial No. 412,762 y 1o clams. (01.371110) Vf 'lhisinvention relates to improvements in con- Yeyer"loaders, i. e., apparatus .adapted while traveling to excavate earth beneath it andto con- VeyA the earth to a' loading point outside the vehicle. 3 f

objectjof thepresent inventionV is to provide apparatusadapted to excavate av large `amount of earth per kfot-)tof vehicle traveland to converge the excavated material from a wide area to a comparatively narrow conveyor for lifting the material-upwardand to one side for loading into another vehicle, for transportation;

` Among the objects of the present invention is the provision ofa conveyor of. great capacity arranged`V in"gasfsn1all a spacejaspossible, together withn'ovel means-forfloosening dirt vor'sirnilar material -and-direeting it to `the conveyer.

^,T.he=present invention is` designed to providea vehicle'which as it moves along loosens dirt over a large erosssectional area, sayior instance of the orderof-nine feet wide and one foot' deep. This material is then concentrated at the lower end of a` conveyor and thereafter elevated by the con-` veyer tora point overhanging one side of the vehicleM/here the material may be discharged into a dumpwagon-or the like traveling alongside the excavating vehicle. The purpose of the invention isll to sexcavate the dirt from the large` cross sec-l tional :ar'ea.;..and `transfer it quickly up the con-A veyerfto 4the Waiting vehicle so that a good-sizev loadtmaybe obtained with a comparatively short traveloffxthe two vehicles.' `The invention has beenedescr-ibed'fin connection with a trailer vehole1but:it:,vvillwbe understood that many of the i ieaturesrthereofwmght be applied to a self-propelledvehicle. L n I f rlnfthe embodiment shown in Figs. 1 to 4, a main framerlasupporting all of the parts is supported by Lwheel means on the axis I I which is located a little` to the .r-earof the center of the vehicle but in suoli-a position that= the load vbefore and -behind the axis II is infcomparatively good balance so that the entire ,devicemaybe plished ,backf wardor forward somewhat after the manner of a cart; thus giving good; maneuverability in either. forward `or reversegdirection.

'The supports forkthes'e ,pins` comprise the hollow posts/36 at the rearof '.the vehicle having lside plates "3l at their upperA ends providing the head pulley 43 and at its lower end is a tail pulley 44. Around these pulleys passes the usual endless conveyer belt supported by suitable idler rollers (not shown) along the entire length of the conveyer. At least one of they pulleys 43, 44 is adjustable longitudinally for tightening the conveyer belt. In the present instance the tail pulley 44 has its shaft 44a mounted in slots in the frame brackets a. At its upper end the conveyer is provided with a small discharge chute which aids in directing 4the discharged material into e, vehicle beneath the overhanging end of` the conveyer. Construction of this partial chute 'may be clearly understood fromy Figs. 1 and 4. It has one side wall only, which begins near the'upper end of the conveyer on that side thereof which is nearer the path of travel of the conveyer loader, and this "side wall then extends outwardly from the end of the conveyer and toward the center line of the conveyer extended. The bottom'plate of the chute is generally triangular in form, as clearly appears, having one side connected with the bottom edge ofthe above described side wall, having a second side extending across the head end of thev conveyer, and having its third side extending substantially parallel to the path of travel of the conveyor loader, as kclearly seen in Fig. 1. It results fromvthis construction that the earth discharged from the side of the conveyor which is nearer the path of width of blade 30 to a zone at the lower end of conveyer 3l. The blade 30 is preferably slightly curved as indicated best in Fig. 2 and the moldboard 42V is provided with the necessary warped surfaces to direct the loosened dirt upwardly at a fairly steep angle,4 say approximately 45 to the conveyer belt and with the necessary lateral movement at the points 42a. and 42b so that all of the dirt from the full width of the excavating blade converges to a relatively limited zone near the tail pulley of the conveyer. One of the ade vantages of thediagonal arrangement of the conveyer relative to the main frame is that it gives more available-area at the lower end of the conveyer crosswise of the main frame and positioned to receive the material from the blade 30 with the minimum of travel. At the same time the angle of vertical-inclination of the conveyer is fixed by the safe angle at which the dirt may be conveyed without rolling back'down the conveyer. Therefore the diagonal arrangement gives the shortest conveyer for achieving the desired maximum heightat the' head puiieyta whne keeping the vehicle. This arrangement is the best possible one for getting dirt excavated by a wide blade to the lower end of the conveyer with the minimum travel of the dirt over the moldboards.

Means is provided for raising and lowering the movable frame about the pivots 35 so. as to control the cutting blade 30. Obviously the moldboardand the conveyer move with the cutting blade .as the movable frame is oscillated. The means for controlling the elevation of the blade comprises a power cylinder and piston motor such as the hydraulic jack 46 having its cylinder pivotally mounted at 41 on a bracket connected with the drawbar I8 and having its piston rod 46a connected tothe crank arm 48 which is rigidly connected with the blade control yoke 49. This yoke comprises a crossbar in the form of a cylindrical tube 49a having rigidly connected to its opposite ends the arms 49h which are pivoted at 49e to brackets on the beam I6. The outer end of each arm 49h is connected by a lift link 50 with one of the vertical side plates 42e of the moldboard. r

Thus the operation of the jack 46 by means not shown will raise and lower Vthe blade 30 relative to the main frame of the trailer vehicle.

Drive means for the conveyeras well as pressure fluid for operation of jacks 21 and 46 may be provided on the trailer vehicle itself. In the present instance an internal combustion engine 5l is mounted on beams 52 which are lsupported between beams I3 and [4. This Vengine drives a shaft 53 which 'through bevel gearing 54 drives shaft 55 which in turn through gearing in housing 56 rotates the head pulley 43. The engine also drivesA a suitable compressor or pump to provide the pressure fluid Vfor the jacks 21 and 4B. The details of this construction form nopart of the present invention and therefore need not be further described.

The second modification shown in Figs. 5 and 6 was designed for the same purpose as the rst Vform but with the added advantage of shortening the travel of the dirt excavated toward the sides of the cutting blade to the conveyerA belt. Since the design 'of this second form is like that of the first form except as regards the moldboard means, similar parts have been given similar reference characters and'will notbe further described here. Y j

Substantially centrally Vof the front; end of the vehicle and directly in fron-t of the lowergend of the conveyer is la cutting vblade 51. This blade as shown isV approximately one-third the total width of the cutting blade means butneed not necessarily be limited to ,thatexactdimension A moldbo-ard 58 conducts the material cut by this blade directly to the lowerend of'the conveyer 3|. Two other blades 59 and60 areA located one f on eachside of the blade 51 and oiset therefrom in a fore and aft direction. Ashere shown these blades are rearwardly 'of blade 51 so as to cut down the necessary travel of the dirt along the moldboards 6| and (i2r respectively, which discharge on the conveyer 3l above the point where the dirt from vblade 51 drops onto the conveyer. Suitable warped surfaces'are provided at the points Bla and 62a` to give the necessary lateral movement of the dirt onto the. conveyer. Vertical side boards 6Ib and 62h connel the dirt on the` moldboards 'and serve as connecting points for the links 50. Preferably Aother vertical dividing boards 63 are provided .between moldboards 58, 6| and 62 so as to direct the dirt in three substantially parallel streams rearwardly for the first portion of its course.
