The object of myfinvention is to provide a road machine having blades made in sections and so constructed that theblades can be set to fit or cutan'ycrown or'c'urvature on 6 the road; to provide a road machine in which the blades can be usedas a cutting edge oras a drag; to provide a road machine which-has several blades all working independently of each other; to provide road machine ad i 10 justable to any width of road; to provide a roadm'achine which is portable and can be quickly dismantled so as to be transported from one section to another; to provide a road machine which has a hitching device at each end; and to provide a road machine which can be constructed of-either wood or metal and which is normally mounted on runners but which can be mounted on- Wheels. I attain-"theseandother objects ofi'ny invention by the mechanism illustrated in the accompanying drawings, in which,

of the several views, except that it is noted that each of the sections of thecutter blade as 11. V

Referring to theaccompanying drawings, I provide longitudinal side beams 'l' and 3,

anda longitudinal central beam 2 to which are bolted the cross beams 7 which have their reduced ends 10, as shown in Fig 6, mounted in the hollow metal housings 9; as shown in Figs. 7 and 8, these housings being suitably fastened to the beams by the angle plates 17. :15 provide suitable cross beams 4 as shown in 1g. 3. l V V i i H V The cross beams 7 are reinforced by the tapered reinforcing bars 8, as shown in Fig. 1. I provide diagonal cross strips 5 and short diagonal strips 6 forming a sort of lattice ends 'of'the members bolted, as by bolts 20, to the longitudinal "beams and permitting of a widening'or narrowing of the entire structure as desired by the substitution of longer or shortercross beams 7 and correspondingly I provide a series of three or more sets of spaced-blades 11 mounted on theunder side of the cross beams 7 and consisting of a series of, sectional blades '11, as illustrated in Figs. 2, 9,10 and11.On the under side ofthe lon- 1 gitudinal beams l and3, I providesuitable spaced runners 12, ofwhich thereare four on each beam, these runners preferably being provided with suitable metal shoes 13, asil 'I' also provide-reinblades 24, as illustrated in Figs. 17 and 18, bolted to plates 14, positioned diagonally to discharge earth laterally from the machine. But one pair of blades 24 are in operation adfa modified form f e nce blade angle;

a Like numerals designate like parts in each 7 jac-ent each cross beam, the; blades 24 being reversed according to the direction of travel of the machine, and arranged to slant rearwardly as shown to discharge loose material to the outside of the machine.

At each end of the machine, bolted to the respective

longitudinal beams

1, 2 and 3, I

rovide drag hooks 15 to which the chains 16 may be attached. The

longitudinal beams

1, 2 and 3 preferably are made in two sections as shown in Figs. 1 and 3 of the drawings; one of the sections of each beam having a reduced end 18, while the mating section has a reduced end 19, as shown in side elevation in Fig. 3, this portion of the beams being rein forced by the beam splices 25 which are secured to the beams by the bolts '20. Beams 1 and 3 are provided with the recesses 21 to receive the reduced ends. 10 of the cross, beams 7. The beams are also provided with the recesses or counter-sunk portions 22 to receive the diagonal plates 14.

It will be noted that the reinforcing bars 8 are provided with a plurality of apertures for bolts. and that likewise the metal housings 9 are provided with a multiplicity of apertures 28 whereby vertical adjustment of the beams 7 and of the scraper blades 11 carried by said beams is made convenient and practicable. It will also be noted that the scraper blades 11 are made in sections as shown in Figs. 9. 1.0 and 11. and they may be adjusted as to length of the entire scra er blade so as to adiust the machine not only to any crown or curvature of the road, but also to roads of different widths.

It will also be noted that as the machine is provided with drag hoo rs at each end.'it is not necessary to turn the machine around.

but that the tractive element-whether horses or tractor can be detached from one end and hitched to the other readily.

Heretofore. road machines in general have been provided with a single blade and if it misses it is necessary to drive back over a hole several. times to fill it. With this machine each of the series of three blades wil function to perform the work. The blades are adjusted to cut at successively deeper depths from forward to rear end of the machine. a

It will also be noted that the runners are spaced from each other. being arran ed alternately with the cross blades so that the dirt can pass out laterally from the machine, a ssisted by the diagonal clearance blades 24. The blades 11 are made in sections of two feet each, thus facilitating, adjustment to the curve and width-of the road. Many roads are only fourteen feet wide; some eighteen, and some twenty; and this diiference in width of roads is taken care of by the adjustability of the blades on my machine. The machine, as will be notedfrom the drawings, has all of its partsbolted together, so that it can be quickly disconnected for trans portation from one section of the country to another.

It is also within the contemplation of my invention to provide wheels 011 which the frame of the machine may be mounted, the wheels being aflixed to the frame so that they can be raised or detached.

It will also be noted that the blades can be used as acutting edge or as a drag. The machine can be constructed of wood or metal.

WVhat I claim is 1. In a road machine, the combination of longitudinal beams, a plurality of cross beams, hollow metal housings in which the ends of "the cross beams are mounted, said housings being adjustably fastened to the longitudinal beams to thereby permit of vertical adjustment of the cross beams.

2. In a road machine, the combination of longitudinal beams, a plurality of cross beams, hollow metal housings in which the ends of the cross beams are mounted, said housings being adjustably fastened to the longitudinal beams to thereby permit of ver tical adjustment of the cross beams, and

scraping blades fastened to the cross beams.

3. In a road machine, the combination of longitudinal beams, a plurality of cross beams, the cross beams having reduced ends, metal housings adjustably bolted to the longitudinal beams and to which the reduced ends of the cross beams are bolted to permit of vertical adjustment of the cross beams, sectional scraper blades mounted on the under side of the cross beams, and angle iron clearance blades mounted on the outer longitudinal beams to discharge material.

4. In a road machine, the combination of longitudinal beams, a plurality of cross beams securely fastened to the longitudinal beams, a series of scraper blade sections bolted to each of the cross beams each of the scraper blade sections having a series of spaced apertures for bolts to permit of adjusting the blades to the width of the road and to provide a plurality of spaced scraping elements for the machine, the cross beams being adjustably mounted relative to the longitudinal beams to permit of vertical adjustment of the entire set of scraper blades carried by each cross beam, and short runners mounted on the longitudinal beams and spaced between the scraper blades to permit of discharge of the material in the space between the runners.

anee blades mounted on the outer longitudinal beams to discharge material, and short runners mounted on the longitudinal beams and spaced'between the scraper blades to pernut of discharge of the material in the space between the runners.
