RICHARD A. BITRNETT, F WILMINGTON, NoRTH cARoLmA I vROAD-S150OTI-IING MACHINE Application filed September 21, 1927, Serial No. 221,025.

My invention relates to a road smoothing machine, and a method and means of im- Y parting a smooth surface to all bitulithic,

asphalt or similar pavements.

An object of my'invention is to provide a roadsmoothing machine which will shave off the high places in a road and willdeposit the shaved-0E material in they low places in the road and will smooth the surface of the 0 roadway.

-Some of the objects of my invention hav ing been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings in which I j 'Figure 1 is a perspective View of my road smoothing machine;

Figure 2 is a plan view of a slight modification of my machine;

Figure 3 is a sectional view taken along the line 33 in Figure 2.

Figure 4 is an enlarged detailed view of the means for raising the machine when it is desired to turn the same.

Referring more particularly to the drawings the numeral 1 indicates the runners of my machine, on which there is adapted to be secured additional runner members 7.

Running from one of the members 1 to the other member 1 is a cross piece 2, whichis disposed at the front end of the machine and at the rear end of the machine there is r the cross member 3 which is adapted to be placed in an inclined position for purposes of smoothing the road. 'Disposed rearwardly of cross member 2 is the angularly disposed member 5, andrearwardly. of this mem her 5 is another angularly disposed member '6, both of these members being at approXimately sixty-five degrees with relation to the longitudinally disposed runners 1. All of these cross members have secured to their front surfaces the steel blades 8. These steel blades 8 have vertically disposed slots 9 therein, and penetrating these slots and the 7 slots 20 in the crossmembers are the bolts 21 having the nuts 22-.thereon, and byreason of this arrangement the'verticalposition of the blades 8 maybe adjusted with relation to the cross members. Secured to the cross members are the upwardly and forwardly projecting members 23 through which the bolts 24 are adapted tobe inserted, said bolts having the'nuts 1O thereon. These bolts are secured in the lugs 24* on the steel blades 8 5.5 and after the nuts 22 have been loosened, the blades 8 maybe adjusted by means of the nut 10 and the bolt 24'. The cross-members are secured to the runners by means of the members 25. The 'memb'ers12 are secured to Q the top portions of therunners 1 on which 'wheelsmay be placedwh'en it'is desired to transport thermachine from place to place when not in use for-road smoothing purposes.

Securedto the cross-member 5 is a steel plate26, and penetrating this steel plate 26 is the screw member '11 which has mounted on the lower end thereof, tho-member 27, the purpose of this mechanism being that when such screw member is placed in the position shown in Figure 4, that the machine will be raised from the pavement-so that it may be turned easily. Secured to this steel plate 26 and, projecting rearwardly thereof-and being secured to the rear portion of the memhers I are the brace members 4.

' A hole 13 is cut in the rearmost portionof thefirst named angularlydisposed blade 8 and a hole is also cut through the cross member 5 in order to allow surplus material to-fall through this hole to be engaged by the blade secured on the cross member 6.

I In the-Figure 2 I'have shownin addition to they structure described in Figure 1, mem

"here 30, 31, 32 and 33, which are placed on top of the runners, 1 for the purpose-of strengthening the structure and. also for carrylng weights such as sand bags in order to glve the best working results, and in this modificatiom'the rear end of. steel plate 26 9 is 's'ecured on top of. the member 31, 0therw1se,the structureis the same as the structure shown in Figure 1 with the exception thatthe cross member 3 has the steel blade 34 secured thereon in the same manner as the steel blades 8 are secured to the other members. In using my machine I find it best to use thesame during the summer months when the bitulithic, asphalt or similar pavement is in soft condition, and when such is the case, the blades will scrape ofi the high places in the road, the front blade which is mounted on the cross member 2 being set at a higher elevation than the succeeding blade, that the shaved-off portions will strike the blade on the cross member 5 which will deposit the shaved-ofiportion in the low places inthe road and any surplus material will fall through the hole 13 and be caught by the blade on the cross member 6, and the 7 cross member 3,--being setat 'an inclined position, will smooth and polish the surface of the road and have a tendency to pack the deposited material in the lowplaces.

I have found that best results can be obtained byapplying to the pavement to be treated I a coating of asphalt with other material and then applying acoating-of gravel orsimil-armaterial, This coating'of asphalt will soften the surface of the road and will also act as-a binderforthe gravel and shavedofi portions which is deposited in the low places in the road. The shaved-off portions and the gravel and the asphalt will be mixed with each otherthorough-ly by the action of the blades on the cross members 5 and '6 V and the large gravel and shaved-off portion Will be deposited in the deeper holes in the road and the smallerportion Wl-llrbB deposited in the shallower'holesin the roadway.

In the drawings and specification I have set forth apreferred embodiment of my invention, and although specific terms are employed, they are used'in a generic and descripill-VG sense only and not for purposes of limiwhen, but the scope of the invention being set forth-in the appended claim.

I' claim:

In a road smoothing machine, comprising longitudinally disposed members; steel runners secured on the bottom of said'members, a front'cross-beam extending from one runner to the other, a rear cross-beam extending from one runner to the other, an angularly disposed cross-beam in the rear of the first cross-beam, a second angularly disposed cro's's-beamdisposed in the rear of the first angularly disposed cross-beam, steeloutting blades secured onthe cross-beams, vertically disposed slots in the cross-beams, vertically disposed slots in the steel-blades, bolts penetrating theslots' to adj ustably hold'the blades with relation to the cross-beams, lugs secured on the upper surface of the crossbeams, boltssecured'to the blades and pene-' tratin-g-the lugs'and a nut on thetop of each of the lugs threadably engaging the bolts. In testimony whereof I affix mysignature. RICHARD A. BURNETT.
