Application filed April 18,

This invention is a novel berm or shoulder grading attachment for road-rollers, road vehicles, tractors, and the like and the principal object thereof is to provide a novel berm or shoulder grading unit adapted to be mounted on and carried by the usual scarifier or other harrow frame pivotally or adjustably mounted usually at the rear end of such road-roller or the like, the blade of the grading unit extending to one side of the road-roller or other vehicle so as to engage the shoulder or berm of the roadway to grade or level the latter while the road-roller or other vehicle is moving along the hard concrete, asphalt or other finished surface of the road.

Another object is to provide an attachment carrying agrader blade which is adjustable so as to grade the berm or shoulder to any i '26 desired angle with the road, the blade'carrying at its outer end an adjustable supplemental grading plate; and the attachment having a guard plate between the blade and scarifier or harrow for preventing materials carried by the blade from moving inwardly into the path of travel of the vehicle.

Another object of the invention is to provide an attachment of the above character which will be readily attachable to or detachao able as a unit from the scarifier or other hinged frame of the road-roller or other vehicle, the entire attachment being raised and lowered by and with the scarifier or other hinged frame; and to provide an'attachment which will grade theshoulder or berm while the vehicle is traveling in a forward direction on the hard finished road surface, close to the edge of the road, causing the berm or shoulder to be graded true with the hard surface of the road. I

I will explain the invention with reference to the accompanying drawings which illustrates one practical embodiment thereof to enable others to adopt and use the same; and will summarize in theclaims the novel features of construction, and novel combination of parts, for which protection is desired.

In said drawings: i

1 is a rearelevation of a road roller showingmy novel shoulder attachment ap- 1930. Serial No. 445,396.

plied to the conventional scarifier, the attachment being lowered into operative position with respect to the road surface.

Fig. 2 is a top plan view of the scarifier and attachment.

Fig. 3 is a section on the line 33, Fig. 2.

The road roller, tractor, or other vehicle is provided with wheeled frame pivotally or adjustably mounted at the rear end of the vehicle, which frame as shown consists of a scarilier of conventional form, having a plurality of parallel arms A mounted on a horizontally disposed shaft Bjournaled atthe rear end of the vehicle, said arms each engaging a cross bar C whereby all of the arms A will be raised and lowered simultaneously by the usual pneumatic cylinder D mounted on the vehicle, through pi ton rod E and yoke F. Bar C is provided with. wheels G at its opposite ends for limiting the downward move-- ment of the scarifier frame, and for limiting the normal cutting depth of the usual teeth or tynes (not shown) which are carried at the ends of the arms A.

The usual tynes or teeth (not shown) which form the digging or hai row tools of the scarifier are normally held in place by means of clamp plates bolted to the ends of the arms frictionally maintaining the teeth in adjusted position. As the above parts are well known they need no further description or illustration herein.

In using my attachment, the clamp plates for the tynes or teeth are preferably removed and an H-beam 2 or other rigid structural beam, is bolted or otherwise removably secured by means of brackets 1 to the ends of the pairs of arms A at opposite ends of the scarifier, the H-beam 2 being disposed substantially horizontally, and extending to one side of the road-roller and forming a cantilever support for the shoulder grading blade. he forward faces of brackets l are preferably beveled as indicated at la in Fig. 3 so as to maintain the web of the H-beam in substantially horizontal position (as shown in Fig. 3) when arms A are in lowered position with the scarifier wheels G resting upon the hard surface H of the road. The brackets 1 are preferably castings secured to the ends H when the scarifier is in lowered position,

of the scarified arms A by means of bolts 11) passing through the same bolt holes in arms A which normally receive the clamp plates which hold the scarifier teeth in place on arms, but brackets 1 may be made in any desired manner and secured to the scarifier arms A or other parts of the scarifier frame in any desired manner.

In front of the cantilever beam 2 at the side of the vehicle is a grader blade 3, attached to beam 2 by means of substantially L-shaped brackets 42 as shown in Figs. 2 and 3, the blade 3 being preferably slightly concave as shown and projecting beyond the outer end of beam 2. The brackets at are preferably riveted to blade 3, and the horizontal legs of the bracketsrest upon the top of the beam 2 narily arranged so that the outer end of blade 3 is at a somewhat lower level than the inner end, which inner end should be just touching the hard concrete road surface as indicated in Fig. 3.

Between the inner end of the blade 3 and the adjacent scarifier wheel G is a longitudinally disposed plate 5, of substantially rectangular shape, having its rear end flanged as at 54 (Fig. 2) and riveted to the forward face of beam 2, and having its forward end braced by means of a bracket 56 secured to the forward end of the adjacent scarifier arm A whereby the plate 5 will be raised or lowered with the scarifier frame and beam 2. The function of the plate 5 is to prevent dirt which is collected and carried along by and with blade 3 from passing inwardly beyond the plate 5 and depositing upon the concrete road H, the lower edge of plate 5 lying in the plane of the lower edge of the blade 3 and preferably substantially tangent to the lower run of the scarifier wheels G, as clearly indicated in Fig. 3.

In event any dirt should pass between the guard plate 5 and the inner end of the scraper blade 3 the same will be thrown back off of the hard concrete road H by a supplemental plate 7 sloping rearwardly and outwardly and secured to the rear face of beam 2, the same projecting outwardly beyond the plane of the plate 5 as indicated in Fig. 2, and the lower edge of plate carrying a flexible member 7a (Fig. 3) of rubber or woven belt which contacts with the road surfaces H and S when the attachment is in operative position.

For supporting the outer end of the beam 2, I provide a flexible cable or member 8 having its upper end secured to the frame of the road roller and its lower end passing through an eye 9a at the upper end of a cli 9 secured to the rear face of beam 2 adjacent its outer end. By adjusting the tension on the cable 8 the outer end of beam 2 may be braced to maintain the blade 3 rigidly in operative position. The horizontal axis of blade 3 however is preferably normally at slight angle to the horizontal axis of beam 2 as indicated in Fig. 7.

At the outer end of blade 3 beyond the end of beam 2 is an auxiliary blade 10 pivoted at its approximate center as at 10a upon the blade 3 and maintained in adjusted angular position with respect to blade 3 by means of bolt 10b,a suitable bracket 100 being also provided adjacent the upper end of the blade 10 for the purpose of stiffening the plate 10 on the blade 3 when in adjusted position.

The entire attachment may be readily connected as a unit to any standard or conventional scarifier by merely removing the scarifier tynes 0r teeth and their clamping plates and bolting the beveled faces of brackets 1 directly to the ends of the scarifier arms A. When so connected the attachment will obviously be raised and lowered by and with the scarifier. When in use the scarifier may be lowered until the wheels G of the scarifier roll upon the concrete or other hard surface H and the blade 3 adjusted to the proper angularity so'that as the vehicle is moved along the concrete road H adjacent the edge thereof the soft shoulder or berm S will be properly cut or graded and the surplus dirt or earth carried along in front of blade 3. By adjusting plate 10 the outer edge of the berm can be given any desired rangu larity to form a gutter or the like, or the plate 10 may be entirely removed.

The cantilever arrangement of the beam 2 with its reinforcing cable 8 forms a rigid structure, and no'extraneous attachments are required to mount the attachment on a roadroller, tractor, or other vehicle carrying a scarifier or other pivoted frame. Any. dirt which should pass between the guard blade 5 and the inner end of blade 3 will be caught by the supplemental plate 7 and thrown back off the concrete H and re-deposited upon the graded shoulder S.

When it is desired to elevate the attachment for purposes of turning the vehicle or for transporting same for operation at a different location it is only necessary to raise the scarifier by the usual pneumatic cylinder D, and all parts of the attachment will be raised above the ground lever. Furthermore when it is desired to dump the material carried by the blade, the frame and blade may be readily raised by the power cylinder above the material carried by the blade, leaving the material behind. Such operation will not affect the relative adjustment of the blade and frame, and is an important feature of my invention. As the road roller travels along the concrete or hard surface H of the road the shoulder or berm S will be left true with the concrete.

I do not limit my invention to the exact form shown in the drawings for obviously changes may be made therein within the scope of the claims.
