This invention relates to road graders and more particularly so-called ba sloping machines, in which the main or road scrap,- ing blade of the machine is equipped at one end with a vertically, angularly adjustable bank slopin blade capable of cutting ditch walls or ot er surfaces at an/angle to the mary object of `the invention is to provide such a device in which the angle of the sloper blademay be, changed not only from the operators station at the rear of the machine but while the machine Iis either moving or standing still.

\The invention consists in mechanism capable of carrying out the foregoing and other objects; which can be easily and comparatively cheaply made; which is highly eilicient and otherwise satisfactory in operation and is not readily liable to get out of order.

More particularly, the invention consists in detailed mechanism by vwhich the sloper blade can be positioned with 'reference to a given position of the main blade to cut an upwardly inclined surface or a downwardly inclined surface, and more particularly in l mechanism by which each adjustment of the main blade angularly in` a vertical plane or angularly in a horizontal plane or vertically or transversely ofthe machine may be used to effect to a 'greater or less extent desired adjustment of the bank sloper blade.

Theinvention further consists in numerous features and details of construction which will be hereafter more fully set forth in the specification and claims.

Referring to the drawings in which like numerals designate the same partsthroughout the several views:

' Figure 1 is a side elevation of the machine illustrating this invention in its preferred form`,'the bank sloper blade being in a posivtion to cuta vertically inclined earth surface.

Figure 2 is a plan, detail view on" the line 2-2 of Figure 1; f 'p i Figure 3 is a plan viewvof'the mechanism of Fig. 1.

Figure 4 is a front view of the machine shown in Figures 1 and 3 with the blade operating to bank slope the upwardly inclined wall of a ditch.

Figure 5 is a changed position view of the mechanism of Figure 4 showin the bank sloper blade adjusted to cut a gownwardly inclined surface, specifically theu per end of the surface on which the rig t' hand wheel of Figure 4 rests.

The mechanism of this invention is applied to a conventional form of grader .including rear wheels 10, front wheels 12,connecting arched frame 14, equipped at the rear with an operators station or platform 16, .the whole drawn over the ground by Asultablepower not shown attached to a drawntongue 18. v

TheA wheels l0 are conventionally, laterally shiftable cross-wise ofthe machine asV shown in dotted lines 20, Figures 4 and 5, and each wheel 10 and 12 is conventionally, laterally tiltable in avertical plane as clearly shown in Figures 4and 5.

Conventionally pivoted at 22 on the front axle mechanism 24 of the machine and below the vframe 14 is a horizontally swinging frame 26-28-30 Whose rear end is conventionally attached through the link mechanism 32 to a horizontally disposed chain l34 passing over sprocket wheels 36 at, opposite sides of the machine, one of which is conventionally operable through a vertically disposed shaft 38 and hand wheel 40 located conveniently to the operators station 16.

By I properly manipulating handwheel 40, i

vthe operator can in conventional manner move chain 34 crosswise of the machine to swing the frame 26-28-30 about pivot 22 crosswise of the machine in a horizontal plane and thereby laterally vary the position of the main road working blade 42.

' This blade 42 is rigidly secured through depending bracket arms 44 to a horizontally rotatable, conventional wheel 46 journaled on' a part 48 of frame 26-28-30. -This wheel 46 is provided on its rear circumference with a segmental worm gear 50 engaged by a conventional worm not shown, located on shaft 52 back .of bevel gear 54 appearing in Figure 1. This latter gear meshes with another bevel gear 56 driven .through a universal joint 58 by a shaft 60 equip ed at its ing wheel 62 in the proper'direction operate the gearing mechanism described to rotate wheel 46 in either direction as desired to change the angular, horizontal. positlon of main blade 42. The universal ]oint 58 permits this operation of the blade 42 1n all horizontal, lateral positions orf the frame 26-.-28-30.

On each side of frame 26-28-30 1s a horizontal pin or shaft 64 to .which is plvotally attached an upwardly extending connecting rod 66. The upper end of each of these rods is pivotally connected to an 1ndependent bell crank lever 68 pivotally supported at 70 on a suitable brac et 72 extending upwardly from the frame 14. The opposite arm ofl bell crank 68 1s pivotally connected at 74 to adownwardly inclined rod or rack 76 having at its lower` end a rack 78 traversed by a pinion 80 operatable throuh gearing 82-84 by a hand wheel 86. s clearly shown in the drawings there is one such hand wheel at each side of the machine adjacent to the operators station 16 and, obviously, by manipulating said hand wheel 86, the operator at the station can raise or lower a selected one or both of the sides of the frame 26-`30, thereby raising or lowering as desired either end of the main blade 42. The pivotal connections 64 heretofore referred to are conventionally such as to permit this adjustment in all lateral positions of the frame 26-30.

The front wheels 12 and the axle 24 therefor are conventionallyrotatablein a horizontal plane for steering the machine through a conventionally connected,late'rally extending shaft 88 conventionally operatable at the rear of the machine through manipulation of hand wheel 90 located at the operators station. j

Pivotally connected'to the forward end of the road-working blade 42 on ka suitably positioned, horizontally disposed pivot bolt 92 is a verticallyy tiltable bank sloper blade 94 selectively movable at the will of the operator between the upwardly inclined position of Figure 4 and the downwardly inclined position of Figure 5. Pivotally attached to thisbank sloper blade 94 at a convenient point near its outer or free swinging end on a pivot bolt 96' is a generally horizontally disposed rod 98 extending in general parallel to main blade 42 transversel of the frame 14 of the machine. Thls rod 98 is pivotally connected at 100 to a depending lock on a cross-head 102, rigdl secured to a reciprocal nonrotatable s aft 104 carried on depending brackets 106 and 107 on the under side of frame 14. ThisV shaft 104. is rendered nonhead 102 is provided with screw threads 112 traversed by the hub 114v of a bevel gear 116 llocated within a suitable housing 118 earried by bracket 107. Also in this *housingand meshing with ear 116 is another beveled gear 120 on as ort shaft 122 terminating in a universal joint 124. .Connected to this universal joint 124.5is` an inclined shaft 126 extendin to therear of the machine and equippe at the operators station 16 with a manuall manipulatable crank handle 128. It is o vious that the operator can by turningcrank handle 128 so move the gearing mechanism in housing 118 as to cause shaft 104 to travel horizontally crosswise of the machine and thus ull or push, as the case may be, rod 98 to orcibly raise or lower the outer end of bank sloper blade 94, thereby changing its angular, vertical position.

' In order to enable bank sloper blade 94 to withstand the strain upon, its outer end occasioned by doing the work required of the mechanism of this invention, a multiplicity-in the particular case here illustrated two- chain hook holes 130 and 132 are provided adjacent to the outer end of the blade 94 each of these holes being selectively engageable by the hook 134 of a chain 136, detachably, ad'ustably connectable to the front ortion o the grader mechanism.

In t e particular case here illustrated, two

brackets v138 and 140 are provided on the front frame of the machine. The lower bracket 138 extends, as shown in Figure 1, a substantial distance forward of bracket 140. Bracket 138 is provided with an end notch 142 and bracket 140 is provided with a corresponding end notch 144 in which the chain 1.36 may be lockingly inserted. By properly combining the chain 136 at its inner end with these brackets and at its outer ends with the holes 130 and 132 in the end of bank sloper blade 94, all desired conditions of chain support required by the blade to work as shown in Figure 4 or as shown in F igure' 5 may be obtained.

There is suicientplay in the universal joint 124, the connection 100 and the connection 96 ,so that blade 94 may be adjusted as desired and described in all the adjusted positions heretofore described of main blade 42.

From the foregoing, it will be seen that assuming blade 42 is'in fixed position, the operator can by manipulating handle 128 raise and lower the outer end of blade 94' to change the vertical, angular position of blade 94; thatl by'detaching the outer end of rod 98 from the blade S34-96, and by properly adjusting the chain 136, the blade larly in a horizontal plane' or angularly in' a vertical plane or up and down without 'angular adjustment or laterally of the machlne.

All the last described adjustments effected through the lchange in position of blade 42 can be made from the operator s station with the machine in motion. It 1s apparent that the operator has all posslble desired adjustments of the bladel under hls control while the machine is in motlon. 'I he only adjustments in the entire machine which require manual manipulation when the machine is at rest are the adjustment of the chain 136 and the disconnection of rod 98 from blade 94 when changing the blade from the'position of Figure 4 to that of Figure 5.

In the operation of the machine onthe road,A suggested by the draw1ngs, the. machine is first positioned as shown 1n F1gure 4-wherein the blade 42 cuts the ditch surface 146 and the blade 94 cuts the ditch surface 148, the two blades 94 and '42 operating to deliver the severed dirt `15O'into the position shown in Figure 5 on road surface 152. After ,the machine has completed the work just described, the machine is then sent along the road over surface'152 as illustrated in Figure 5 with the blade 94 lowered as shown in that figure to then scrape road surfaces 146 and 152 to thereby deliver lthe loose dirt olf at the right hand side 154 of road surface 152. j

In the complete operation of the device, the wheels 10 and 12 are, by conventional means not shown, tilted and wheels 10 are laterally shifted as the road conditions may require to-properly perform thel necessary work.

j The chain 136 at the. front of the ma- Y chine, supporting the front end of the sloper blade 1s, of course, a tension device and it will be so referred to in some of the claims. The sloper blade is, of course, ybroadly a supplemental blade and will be so referred to in some of the claims.
