1 Claim. 1
This invention relates to a road edger operable in association with the usual moldboard of a road grader so that the dirt or other material scraped up by the moldboard will be delivered only to a predetermined line such as the edge of a hard road surface where it will be diverted back onto an area following that traversed by the grader blade.
An object of the invention therefore is to provide an apparatus of the above mentioned type and one which is particularly useful in treating the berm of a road and preventing the development of a windrow adjacent the hard road surface or the throwing of dirt, gravel or the like from the berm onto said hard road surface.
Other objects of the invention will appear hereinafter, the novel features and combinations being set forth in the appended claim.
In the accompanying drawings,
Fig. 1 is a side elevational view of a road grader incorporating the features of my invention; and
Fig. 2 is a plan view, with many parts eliminated, showing the important relation of a grader blade and road edger.
Referring particularly to Fig. 1 of the drawings there is illustrated a substantially standard road grader including the main frame It, front steering wheels II, power driven traction rear wheels I2. The grader is provided with the usual drawbar I3 having standard adjusting means and carrying a circle I4 which through appropriate supporting arms is provided with a moldboard I5 which preferably may be slidably adjusted along its axis relative to its supporting mechanism.
In Fig. 2 of the drawings the grader is shown as working along the berm of a road adjacent a hard surface, the lower wheels as illustrated in Fig. 2 of the drawings being shown running on said hard surface. A grader blade I5 will scrape up the dirt or gravel on the berm, which dirt will flow at least in part over the trailing edge due to the moldboard I 5 being inclined to the line of draft of the vehicle which, of course, is along the longitudinal axis thereof.
The tendency under normal circumstances is for a windrow to form along the trailing edge of the moldboard I5 and sometimes this windrow is actually formed on the hard surface adjacent the berm. To the usual grader there is attached an edger I6 which includes an upright plate I! normally parallel with the line of draft of the vehicle which will be parallel with the side edge of the hard surface of the road. The edger plate I! preferably is normally positioned adjacent the hard surface so that the dirt which flows rearwardly from the trailing edge of the moldboard I5 will be diverted by said plate I! and thus not distributed on the hard surface of the road.
The plate I? is spaced slightly from the trailing edge or end of the moldboard 15 but is sufficiently close thereto to have an effect upon the flowing dirt. It is pivotally mounted intermediate its ends on a bar I8 which in turn is carried by brackets I9 attached to the circle I4. At its forward end the plate I7 is provided with a pivotally connecting adjusting bar 25 which is adjustably attached to the bar I8 so that the angle of the plate I? relative to the angle of the moldboard I 5 may be adjusted particularly in view of the fact that through the circle adjusting mechanism (not shown) the angle of the moldboard I5 may be adjusted relative to the line of draft.
Pivotally attached to the upright plate I! is a trailing extension plate or portion 2| which is adjustably connected by an adjustable bar 22 to a bar 23 attached to the rear of the circle mechanism Id. The extension or trailing plate 2i swings inwardly from its leading edge relative to the line of draft and tends to direct material flowing around the trailing edge of the moldboard I5 and stopped by the banking plate I! and scatter it over a path which has just been traversed by the moldboard I5.
It is thus evident that the edger IE cooperates with the moldboard I5 of a standard grader to insure a neat grading operation on the berm adjacent a hard road surface which will prevent the formation of a windrow and which will prevent dirt or gravel from the berm getting on the hard surface in any objectionable amount.
Obviously those skilled in the art may make various changes in the details and arrangement of parts without departing from the spirit and scope of the invention as defined by the claim hereto appended, and applicant therefore wishes not to be restricted to the precise construction herein disclosed.
Having thus described and shown an embodiment of the invention, what it is desired to secure by Letters Patent of the United States is:
R/oad grading apparatus including a grader frame, a rotatably adjustable circle carried by said frame and a mold-board adjustably carried by said circle, support means carried by said c rcle extending laterally thereof, an edger at one side of said circle and at one end of said moldboard including an upright front plate and an upright trailing plate, pivot means connecting 3 said trailing plate to said frontplate, and means adjustably connecting said plates to said circle, said means including a bracket on said front plate, pivot means interconnecting said bracket and said support means, a second bracket on said front plate positioned at one side of said first bracket, a connector member extending between said second bracket and said support means for adjusting said front plate upon said pivot means whereby when said moldboard is adjusted to 00- cupy any of various generally transverse positions said front plate may be positioned to extend substantially parallel to the direction of travel of the grading apparatus, a bracket on said trailing plate, and connector means extending between said bracket and said support means for adjusting the angle of said trailing plate with respect to said front plate.
