To all whom t may concern; 'It f Be it knOWn'thatIQJOHNW. BRANNAN',l a citizen of the vUnited States, residingzat Grand'lfsland, inthe' countyof Hall and State of Nebraska, have invented fcertain new and use-ful 'Improvementsffin' Road Drag or Grading Machines7 of vvhiohpthe following is a specification, reference being had to the accompanying'dravvings. f l* It is the purpose'of he present invention to provide a machine of this character in-` volving mean'sfornotronly loosening up the" ling the object tor fill the roller with fluid,

places and the ruts, but also for eliminatingthem, vgradingthe road and rolling, 15

leveling and'iiattening'the same; l i

' 'Anotherfpurpose consists in theprovision i of fa i hollow roller.' following the grading andleveling'means of the machin@ .for not only flattening the road, but also forpack-- ing the earth, to insurea solidy bed, -it' be.

the object being 'to permitthe dirt graded from one'place or'another` to be dropped in 'lower places, thereby ,uniformlyl grading thebed- L E -v i 5 A" still furtherl purpose i. consists in" a l barrow `device -including yteethffor looseni ing up the high place's'in the roads, infcorniV bination with means for raising theharrovving device, forfuniformlyr controlling the action of the same.

` 4Connected to the forward angle iron or bar- 'by means of hinges '23. 'are metalli-C straps '211 preferably of steel, which arein turn connected tofa harrow bar 25, upon which h'arrow vteeth 26 are mounted. A

is/connected, eitherby bolts,*rivets drthe like 34. If'bolts'are usedf for connecting the blade to the bar 32, th'enitis obvious that'the road grading-blade `may be easilyI and quick-y y detached, for renewal, or for repairs. It will-be noted that the bar 32 and, its blade are disposed on an in'cline transversely of the frame, so as lto deflect the dirt 'andthe like to one side of thermazchine, a's they vtravels over the road bed.

Securedvupon the'angle iron or bar 32 as at 39 is a footpedal 4:0, upon which foot pressure by the operator may be applied, to facilitate cutting the hard spots and high places of the'road bed. In kother words should one side of the roadbed have hard portions or vhigh places which yare Vnot touched, or only partial-ly so, the harrow teeth, then the operator may apply pressure upon thevleft hand side of the road grading blade, to insurecutting awaythe hard portions and insure leveling thesurface of the road. l
