Claims.

This invention relates to new and useful improvements in road graders and the primary object of the present invention is to provide a road bank sloping attachment for, graders that will in no way harmfully effect the normal and intended use of a road grader.

Another important object of the present invention is to provide a, sloping attachment for road graders that will bring the dirt on a bank up and on top of a fill and which will leave the ditches free from loose dirt and which will also line up the shoulders in one operation.

Yet another object of the present invention is to provide a sloping attachment for road graders that willdirect the loose dirt on a bank on top of the fill so that the dirt so moved on top of the fill can be used for finishing the top of the y road.

A furtherobject'of the present invention is to provide a sloper attachment for graders or auto-patrols that includes a blade mounted at the rear of a grader, causing all the pull to come from the rear of the driving wheels of the grader, and thereby eliminating any side draft.

A still further aim of the present invention is to provide a bank sloper including a novel and improved means for mounting the sloper on a grader, so that the sloper may be quickly and readily applied to'or removed from a grader in a convenient manner to cooperate with the normal earth moving blade of the grader.

I Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in'which:

Figure 1 is a side elevational view of a well known type of grader and showing the present invention mounted therein;

Figure 2 is a plan View of Figure 1;

Figure 3 is a front elevation view of Figure l;

Figure 4 is an enlarged fragmentary view showing the means, in section, for attaching the invention to the left arm of a'grader;

Figure 5 is an enlarged detail view showing the manner in which the forward portion of the main connecting means is attached to the forward end of'a" grader;

Figure 6 is an enlarged detail view, partly in section, showing the manner in which the sloper blade is attached to a beam at the rear of the grader; s

Figure '7 is a view similar to Figure 1 but showing the invention in modified form; and,

- Figure 8 is a front elevational view of Figure 7.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l0 represents a conventional well known type of road grader having the usual earth moving blade l2 mounted beneath its forward portion and below a vertically swingable lift arm I4 which also forms a usual part of the grader. l l

The present invention does not attempt to claim the above well known structure but is merely an attachment therefor that will properly slope thebank of a road as the blade 12 is leveling a road or fill.

In order to accomplish the desired results, there is provided an elongated sloper blade 16 whose inner end supports a tube l8 in which a longitudinally extending bolt 20 is mounted. A ball member 22 is fixed to theouter end of the bolt 01' rod 20 and enters a ball seat or socket 24 in a block 26 thatis end portion 28 of a beam 30. The ball member 2?. is confined in the seat 24 for universal movement by a retaining ring 32 that is secured to the block 26. V V

The end of the beam 3il remote from the block is secured to the rear end of the grader by a pair of horizontal plates 34 and a vertical pin 36 to permit removal of the beam from the grader. An arm 38 projects laterally and forwardly from the beam 30 and is secured between upper and lower plates 40 at the rear of the grader. 7

An upper and lower pair of enlarged ears 42 are fixed by welding or the like to the outer end of the sloper blade I6. The eye end M of an upstanding arm 46 is held between the cars 42 by a vertical pivot 48 that extends through the ears 42 and the eye end 44. An inclined tube 59 is fixed. by welding or the like to the arm 465 and receives the rear end of a rear tubular member 52. The forward end of the member 52 is slidably mounted in a forward tubular member 54. The rear end of an elongated pitman or rod 64 is attached to the arm 46 by a ring 66 carried by the rear end of the pitman and which ring is slidable in an aperture in the arm 46. Another ring 68 at the forward end of the pitman engages a ring member 10 on a holding plate '52 that is welded or otherwise fixed to the blade l2.

Means is provided f0 connecting the member 54' tothe lift arm 14 of the grader. This means comprises a pair of elongated tubes 7 and 76 that are connected by a rod 18. The tube 16 is provided with a plurality of longitudinally spaced Welded to the depending.

openings 80 that will selectively register with a transverse opening 82 in the rod 18 and a bolt 84 extends through the opening 82 and a selected one of the openings 80 to adjust the rod 18 longitudinally within the tube 16. The uppermost end of the tube 14 is pivoted between a pair of cars 88 on the rear end of the member 54 by a pivot 90;

In practical use of' the invention, the blade 16 will extend downwardly and forwardly from the rear of the grader as shown in Figure 1 so that as the grader is moved forwardly loose dirt from the bank B will be moved to the road R. The location of the blade [6 at the rear of the grader and behind the driving wheels of the grader is quite important and aids in reducing side draft.

The blade it may be raised. su'flicientl'y by the arm M, to clear fences and the like obstructions and the inclination of theblade 16 may be varied by actuation of the arm l4 and through longitudinal adjustment members or tubes M and 16 relative to each other.

Attentionis now directed to Figures 7 and 8, wherein there is disclosed the present invention in modified form. In this embodiment, the auxiliary' blade I60, is attached to the rear of the tractor by the same means described in Figures 1-6 inclusive; The outer end of the blade Ilia is secured to the grader frame Hla by a framework 52a consisting of an elongated member 5411 whose inner end is pivoted as at 620. toan anchor plate 56w mounted on the grader lila. The framework 52a also includes bracing members 5811 that are welded together and to the member 52a.

The grader Hla; being; of conventional structure is provided with the usual blade lift arms A from which hanger rods Ba depend. One of these lift arms A is connected toears E' on the framework 520 by a telescoped connector 60a. The connector 60a is also secured to the grader by a pitman 62a.

Through the structure above described, the framework 52a and the outer end of the blade 16a may be selectively raised or lowered as the lift arms A of the grader are raised and lowered by the usual operating mechanism of the tractor.

The lower end of. an arm 46a is pivoted between a pair of cars 42a fixed on the outer end of the blade 16a. by a vertical pivot 48a and to the upper end of the arm 45w there is fixed a sleeve 5011; that embraces the member 54a. The arm 46a: is connected to the blade l2 of the grader by a rod 64a whose ends support: rings 66a. and. 68a. The ring 68a extends through an aperture in the arm. 46a

and the ring 68a; engages another ring 100, secured. to the blade 12a.
