JAY HUGHES, OF ATKINSON, NEBRASKA.

i Roan-seamen.

To all mama may concern Be it known that I, JAY HUGHns, a citizen of. the UnitediStates, residing at Atkinson,

' in the county of Holt andSt-ate of Nebraska,

s more fullydescribed, illustrated have invented certain newand useful Im provements in Road-Scrapers, of. which the followingiis a specification. YThis invention relates to 1 road scrapers, and the primary object of the invention is the provision ofaroad scraper which has a plurality of rotary cutting disks positioned forwardly of the scraping blades, for jefli ciently preparing the surface of ahighway, Another object of this invention is the provision of a road scraper which has traction wheels adj ustably supported upon the forward end thereof, so that the scraper body'may beelevatedwhen desired. a 4 f1 With the foregoing andotherobjects in view, this invention consistsin suchiiove'l features of construction, combination, and arrangement of parts as will behereinafter companying drawings, and claimed,

drawings, wherein like characters designate like or corresponding parts throughout the several views, and in which v n I Figure 1 is a top plan view of the im proved road scraper, l

mg. 2 is a side elevation or eats,

scraper,

, Fig. 3 is a rear elevation of the improved scraper, v y

, Fig. 4 is a fragmentary bottoml plan of the road scraper, p

Fig. 5 is a detail viewofth'e scraping blade, and W Fig. 6 is across sectional view on the-line 66 of Fig. 5. 7

Referring more particularly to the drawings, 1 and 2 designate sections of which the road scraperis composed, which sections are, connected by flexible members 3. The sections 1 and 2 are parallelograms, having their ends disposed obliquely to their sides,

as is clearly shownin Fig. 1 of the drawings, and they have a plurality ofbraces 4 secured tothe inner walls of their sides and extending diagonally across the corners thereof, for securely bracing and strengthening the frames 1 and 2. Theframes 1 and 2 have longitudinally extending strips 5 mounted upon their upper edges, which strips form base supports for bearings .6.

Shafts 7 arejournaled intliebearings and they have. drums 8 mounted thereupon, which drums are adapted for [rotation by the angled'ends of the shaft, which "form crank handles. Flexible members 9am se- 'cured'to the drums "8, and to eyelets10, i

which eyelets are formed upon the substantiallytriangular shapedframe 11, and yare formed at the apex of one angle of the triangle. The triangular frames 11 are "con? nected to bearings l 12, which bearings are formed upon the upper ends of brackets 14, and are'secured in; any suitable manner to "blocks '15, which blocks are pivotally mounted in the forward end of the parallelogrammatical shaped frames 1 and 2. q

The blocks 15have armsic securedthereto, which arms have their' vlower terminal ends bifurcated to'form axle supporting arms 17. Supporting wheels 18fa're mounted within thebifurcatedend's of the arms 16, and the supporting wheels 18' areproQ vided for light bearing engagement with scraper is traveling when the flexible meme here 9 are wound about the drums 8, sofas toraise the forward end of the frames land 2 to permit trash or otherundesirable fma- .terial to fall out of the frame, should the same become clogged therein.

The rear ends 20 of theframes 1 and 2 are of decreased height with respect to the sides of the frame, asis clearly shownjin Fig. 3 of theidrawings. The frames 1 and 2 have bearingbrackets 21 mounted upon the under surface of the longitudinally extending plates 5, and also bearing brackets 22 secured to the inner surfacesof the sides of the frame, a short distance rearwardly of the blocks 15, and the bearing brackets 21and 22 have journaled therein shafts 24. The

shafts have mounted thereupon a plurality of harrowing or cutting disks 23. The shafts 24: are positioned horizontally and obliquely of the lin of travel of the frames 1 and 2,

as is clearly shown in Fig. 4 of the draw-f ings, and they are also positioned for opposite angled extension to the oblique ends of the frames. v i

, The braces 25 which are positioned toward the center of the frames 1 and 2, have plates 26 secured thereto, which plates ex-' tend across the frame parallel with the oblique or angled ends of the frames, and the plates 26 have scraping blades 27 de tachably secured thereto, which scrapes blades have their lower terminal cutting edges curved outwardly, as is shown at 28 in Fig. 6 of the dravving ;s.-v 1
