An elongated trough generally designated as 2?] is disposed lengthwise of the frame i5 and includes a bottom plate 2i having secured to the oppositelengthwise edgesthereof flanges 22, and the fiangesZZ haveextending right angularly and upwardly therefrom side walls 23. The side walls 23" terminate at their upper edges in outwardly projectingflanges 2d which are secured'by fasteningmean'sidto the upper angle members it; The bottom member 2| vof the trough 29 has fixed'to the opposite lengthwise edges thereof a pair cinch-metallic runners 26 which are secured to thebottom 2i by'iastenihg members 21.
A conveyor generally designated as 28 is movably disposed within the frame [5 and comprises a pair of endless chains 29 having their upper runs engaging over the runners 23. A plurality of transversely extending cleats 3B are securedbetween the. runs of'the chains 29 being secured to thechains 29-by means of triangular lugs M which are secured tospaced links of the chains 291 The'chain's 29" are trained over a pair of driving-sprockets 32 which are secured to a shaft 33 journalledin bearings fi l-carried by the frame 15 adjacent the rear of the frame. The chains 29'are also trained over idler sprockets 35 carried by an'idler'shaft'iifi' which is journalledin a pair ofa'djustable bearing blocks 37 carried by the for ward-end ofthe'frame' l 5; v .The shaft SS- has fi'xedthereto a relatively large s'prooket t about which a-chain 39 engages, and
the chain 3i engages about a relatively small sprocket' flfl' which is carried-by an intermediate or jack shaft dijournalled in bearings t2 carried by ythe frame it; theretbarelatively large pulley d3 about which more endlessbelts 4d engage; and thebelts 4 lengage= aboutfldriving pulleys 35 carried by a power shafted;- The shaft t3 is rotated by a power member" 4? which may be an electric motor or an internal combustion' engine The trough 2i! isformed between the ends thereof with an" opening es, and a grill or screening member 49*engagesbeneaththe opening .8" and isadapted toascreen out any loose material which Referring-to the drawings; the" nusar l5 designatesgenerally an elongated frame structur'e' 'which 'is form'e'cl of' -upp'eran'gle' members" i 6" is movedfalongthe bottom of the trough -2El 2 The sc-reen or grill'deis formed of a-plurality' of parallellengthwiseextending bars 50 which are securedto aloopedframe- 5i, and'therear The shaft ti has fixed and forward ends of the frame are secured to transversely extending bars 52 which are secured by fastening means 53 to the bottom 2| of the trough.
A mobile frame 55 is disposed below the frame l5 being provided with a pair of wheels 55, and the frame 54 is connected to the rear portion of the frame 85 by means of elongated links 55. The links 55 are pivotally connected between the frame i5 and the frame 55, the purpose for which will be hereinafter described.
A second pair of elongated links 5'! are pivotally connected at their inner ends to the frame 54 and are provided at their outer ends with rollers 53 which movably engage beneath the frame I5. The links 5'1 are adapted to be locked relative to the frame 5 1 so as to either extend or retract the frame i5 by means of a flexible member 59 which is trained over a pulley carried by the outer portions of the links 57!. The flexible member 59 is secured at one end to the sheave frame 5i and is then trained about an intermediate pulley 62 carried by the frame E5 forwardly of the pivotal connection of the links with the frame IS. The flexible member 59 is extended rearwardly and is wound about a winding drum 6-3 which is carried by a'shaft M- journalled across the frame 55.
A worm gear 55 is fixed to the shaft 54, and
the gear has meshing therewith a worm 65 which is slidable but non-rotatable on a shaft 6?. The shaft 51 is journalled at one side of the frame l5 lengthwise of this frame in bearings 58 and 59.
A spring Hi is disposed about the shaft 6? bearing at one end against one end of the worm 55 and bearing at its other or rear end against a collar H which is fixed on the shaft 61. The
shaft 5? is rotated by means of a bevel gear 12,
which is fixed on the shaft 4|, and gear i2 is adapted to mesh with a selected one of a pair of gears i3 and it. The gears 73 and '54 are fixed on the shaft 5'! being held in spaced apart relation by means of a sleeve 15 engaging about the shaft 61. A selected one of the gears 13 or 14- is moved into mesh with the gear i2 b means of a shifting fork is pivotally carried by a supporting bar Ti and engaging between a pair of collars 18 which are secured to the shaft 61. The shifting fork 15 includes an elongated lever [19 having a spring pressed pawl 85 which is adapted to engage in a notch 8! carried by an arcuate keeper bar 82. The dog or pawl 89 when engaged in the keeper notch 3! is adapted to hold the gears '53 and it in neutral or disengaged position with respect to gear 12.
In the use and operation of this elevator, the rear end of the elevator may be coupled to a tractor means by means of coupling or hitch members 83 which are carried by the rear end of the frame l5. When it is desired to use the elevator for raising grain or other material, the elevator is raised at one end by operating the power member 41 and shifting one of the gears on the shaft 62 to provide for rotation of winding drum 53 in a winding direction.
Winding of the flexible member 59 on drum 63 will pull the links 5? rearwardly and upwardly so as to thereby raise the forward end of the frame [5. When the elevator is disposed in the desired inclination, shaft 5? is declutched or uncoupled from shaft 3!. The material, which may be corn or other grain, is then discharged onto the lower end of the conveyor, and as the corn which is on the cob passes over the screen or 4 grill 49, the loose corn or other relatively small material will drop through the screen 49. The remaining material will be carried upwardly and discharged from the upper end of the conveyor 28. By providing the non-metallic or other runners 26 for the chains 29 on the upper runs of these chains, a substantial amount of noise is eliminated, and in addition the wear on the chains will be very materially reduced.
Where the material is relatively small such as small grain or the like, a plate may be disposed over the opening 48 in the trough bottom so that the small materialwill not drop through the opening 18.
'This elevator will provide a means whereby grain or other material may be elevated and discharged into an upper storage bin, and where electric power is not available, the power member 41 may be in the form of a small internal combustion engine.
