SHOULDER-FINISHING ATTACHMENT EOR ROAD MAGHIIT ES.

Application filed April 27, 1927. Serial No. 186,950.

This invention is a novel improvement in shoulder finishing attachments for road machines and the principal-object thereof is to provide a main and auxiliary outboard shoulder finishing attachment for tractors, road rollers, and the like whereby the earth adjacent the margins of concrete or other hard surfaced roads will be graded, trimmed, or finished to the desired width and angle 1 with respect to the hard surface of the road,

when the tractor or roller provided with my attachment is drawn or driven over the hard road. The usual standardconcrete or other hard surface highway must, by law,

be provided with a belt or strip of earth outside the limits of the hard surface of the road, which belt or strip must be leveled off,

either horizontally or sloping downwardly, from the outer margins of the concrete.

Another object of the invention is to provide a shoulder finishing attachment for road machines which can be readily attached to or detached from the tractor or road-roller without altering the structure of the tractor or roller.

A further object of the invention is to provide an auxiliary outboard grader blade disposed in advance of the main outboard grader blade, and sloping in the opposite direction for pushing the earth into the usual cavities adjacent the side margins of the concrete or like roadway, the main outboard grader blade grading the earth thus pushed up by the auxiliary blade and leveling same flush with the surface of the concrete; the two blades being supported entirely by the vehicle frame so that the shoulder of earth will maintain a fixed angularity with respect to the hard surface of the road.

Other minor objects of the invention will be hereinafter set forth.

I 'will explain the invention with reference to the accompanying drawing which illustrates one practical embodiment thereof to enable others familiar with the art to adopt and use the same; and will summarize in the claims the novel features of construction, and novel combinations of parts, for which protection is desired.

In said drawings:

Fig. 1 is a top plan view of a road ma- A above and slightly chine equipped with my shoulder finishing attachmen Fig. 2 is a side elevation thereof.

Fig. 3 is an enlarged section on the line 33, Fig. 2.

The attachment is illustrated in connection with a road roller of the three wheel type, such as shown in Letters Patent No. 60 1,607,227, the roller consisting of opposite Slde frames A, connected at their front ends by a trunnion head B in which the yoke of the front roller C is journaled, the rear end of the side frames .A being supported by axle D carrying the rear wheels E at its ends exterior to the side frames. Side frames A extend in rearof the axle D and usually carry an operators latform F. A motor G ]S usually mounted upon the side frames in front of the rear axle D. The above type of roller is well known and needsno particular description herein. The type of road machine however 1s immaterial and m attachment may be used in connection with any other type of roller, tractor or road machine.

As shown in the drawings, my attachment COIIlfPIlSBS a transversely disposed beam 1, pre erably a channel bar, mountedupon the rear ends of the side frames A and rojectmg on one side beyond the rear w ieel E, said beam 1 being detachably connected to the side frames with the flat side of the channel bar disposed towards the front. Disposed parallel with the side frames A exterior to the adjacent rear wheel E is a longitudinal beam 2, preferably a channel bar having its rear end detachably connected to the transverse beam 1, and its forward end supported by a trunnion ring 3 carried by a bracket 3 mounted upon the upper face of said beam 2, said trunnion ring 3 engaga ing a collar 4 which projects beyond and is mounted upon the end of the axle D. Collar 4 is provided with a circumferential shoulder 4 intermediate its length, the portion of the collar 4 exterior to shoulder 4 being adapted to receivering 3; and a plate 4" is removably bolted or otherwise connected to the outer end of collar 4 whereby trunnion ring 3 will be rotatably secured upon collar 4 between the shoulder 4" and the plate 4";

I The forward end 2 of beam 2 extends beyond the trunnion 3, and is inclined outwardly and forwardly at an angle of approximately 45 as shown in Fig. 1 and terminating at a point substantially oppositethe front portion of wheel E. I

Upon the beam 2 is a bracket 2 having a perforation through which extends an adjustable hook rod 2 which engages an eye bolt 5 on the upper inner end of the main scraper blade 5. Blade 5 preferably comprises a slightly curved plate having an angle bar 5 disposed along its upper edge, the eye-bolt 5 being passed through a perforation in the horizontal flange of bar 5". Blade 5 slopes outwardly and rearwardly at an angle of approximately 45 as shown in Fig. 1 and passes under the outer end' of the beam 1. An eye bolt 5 in the bar 5 at the outer end of blade 5 engages a hook rod 1 extending through perforations in the outer end of beam 1, said rod 1 having a nut on its upper end whereby the height of the outer end of blade 5*with respect to the ground may be adjusted.

The outer end of blade 5 is provided with an adjustable extension plate 6 which is bolted at its lower end as at 6 to the blade 5 and has a series of perforations 6 in its upper end adapted to register with a perforation in the upper end of blade 5 for the reception of a bolt whereby the angularity of the-extension 6 with respect to blade 5 may be adjusted.

From the above it will be seen that the blade 5 with extension 6 is pivotall suspended by the eye bolts 5 and 5? an hook rods 2, 1, and hence may be readily adjusted vertically by merely adjusting the said hook rods.

In order to hold the blade 5 in vertical position for operation when the machine is moving forward, I provide so-called blade ushers 7 and 8, comprising straps rigidly but removably connected with the beams 1 and 2 respectively, said beams extending outwardly and forwardly to meet the top of the blade 5, and outer ends of blade pushers 7 and 8 being curved to conform with the curvature of blade 5 but being disconnected therefrom. By the above construction when the machine is moving forward, the pushers 7' and 8 will maintain the blade 5 in vertical scraping position, but when the machine is moving backwards the blade 5 may hinge forwardly away from the curved outer ends of blade pushers 7 and 8 if an obstruction is encountered by the blade.

On the out-turned forward end 2 of beam 2 is a similarly auxiliary blade 9 which is suspended by eye bolts 9 which engage adjustable hook rods 2 which pass through perforations in the beam 2, and a blade pusher, 10 is removably connected to the underside of beam 2 between the hook rods and slopes forwardly and downwardly to meet the upper end of blade 9, the outer end of pusher 10 being curved to conform with the curvature of blade 9 whereby, as the machine is moving in a forward direction blade 9 will be held in rigid position but may hinge forwardly if the machine is moved in the opposite direction.

As above stated, the short blade 9 is inclined in the opposite direction from and is disposed in advance of the main blade 5, and as the machine is moving forwardl auxiliary blade 9 will scrape earth into t ie usual cavity or recess at the margin of the hard concrete road, and the main blade 5, following blade 9, will then level the filled-in earth flush with the surface of the concrete if blade 5 is adjusted to the proper height. The attachnient may readil be connected or disconnected as a unit 1:0m the road machine by merely removing beam 1 and the trunnion 3; and the parts of the attachment may be further disassembled for convenience in storing or shipping. The attachment requires no alteration of the machine except the addition of collar 4 to the end of axle D.

I do not consider my attachment limited to use only with road rollers of the ty e herein described. Obviously same ma e used with any other type of road machine. Also I do not consider my invention limited to the I exact details shown in the drawing for obviously changes may be made therein within the scope of the claims.
