Application mew-Mama 27, was, eager No. 91,883 1 i Renewed March 1928 This invention relates to machine or im plement for operating on roads, and partieu.- larly toa road drag orscraper- Assisnwell known, the highways are -now :regularly Worked by operativesso as to be kept in proper condition. ;As the road-deteriorates and becomes damaged by 1 the Weather, holes or rats are often forlned'stherein, dirt is Washed away from one place and piled :up in another. Itis desirable; therefore, to have a machine or' dragwvhieh can readily be 'manipulated so as to bBllSGdQtO fill up holes: or rats and :to either deposit material at r one place or remove thewsame; It 'is an obj ect: of this invention, therefore, to provide a road drag or scraperjhaving co-operating pairs of blades, theblades: of said pairs being inclined Jataan angle to each angle bars; The members 6 are connected subshantially midway of their lengths by a a pair of members 7 illustrated as angle bars, havingtheirveiticalflanges incontact. ,The

:members 5 and theforward members 7have extending therebetween a pair of parallel bars 8 also illustrated as angle bars, which -m'embers' 8 :are bolted or riveted to themeln- J .bers 5 and 7. Another pair of parallelbars 9 also extend from the forward member '7 itothemembe-r 5, being shown asanglebars i and toward the 1 center of the machine, thus 5 forming pairs of forwardlyconverging bars. A pair o'i' parallel angle bars :lOalso extend from the rear nember 7 to the rear member ,5 and another pair ofba rs 11 shown-as angle 1 bars extend from the rearmembers 7 to'thefflfi Ohl1B1,t0getl1CI' with meanslrfor swinging said blades about"horizontal axes. :3 r g It is a further object of'the invention .to provide a "road drag or serfaper" having a frame, a pair=0f blades at the-foiiwardlpon tion thereof, diverging; outwardly and forwardlyand-alsohaVin-g"a pair of blades at the rear portion diirerging 1 outwardly *i fand rearwardly, all ofasaid blades having means for swinging the same about 1 horizontal axes rear members 5, beingflbolted to said meni-f bers and the bars 10 and 11 11161111611331 nvardlyland towardthe'center of the frame,

Referring to the drawings, a road, drag or scraper is, shown: comprising; frame: having horizontal andparall'el ,f'ro'ntwandzrear members 5 1 connected eat their ends -by ithe parallel 'side menibers 6. =While "the? members 15-; and 6 may "be made. of' any desired material, in the embodimentroi the invention illustrated they are shown as made, from curedzto 'said bars. The levers 17 haverhan. .dle's at their upper ends and a" pawl grip han'dle 19is pivoted to each of said levers connected by :a link 20 to a pavvl21 guided in-a=,lu,g ?17 on the-leve'rs17 and adapted' 'to seat in the notches18 of the segment 18 @tvveen the handles 19 andlever 17 tending tohold the pawl 21 in engaged position. @lt

a springQQ- preferably being disposed be-ilo a side hitch to the device. as when will be noted that the blades 15 at the forward portionof the frame have their inner ends spaced and said blades diverge forwardly and outwardly, one of said blades, as

llustrated that shown at'the right of Fig.

1, has an extension portion 2 1 bolted thereto which extend past the inner edge of the other forward blade 15, said extensionblade being readily removable and held in place by headed and nutted bolts. The rear blades 15 a-sxshown, diverge outwardly and rearwa-rdly and one of said blades has its inner end extending past the inner-end of the adjacent blade and curved somewhat around the latter. A seat 25 is carried on an upwardly extending bar 23 secured to the forward member 7 substantially at the center thereof.

The forward member 5 has spaced eyebolts 26 secured therein, between which extends a chain 27 having its ends secured in said eye-bolts. The chain 27 is of the ordinary straight link type and a loop member 28 is provided through which the chain passes, said member 28 having a ring 28* at one end and an elongated loop portion 28 with parallel sides at its other end, the plane of the portion 28 being; substantially at right angles to that of the ring 28 In operation the device will be hitched by means of member 28 to suitable traction means such as horses or a tractor, and drawn along with the blades 15 in contact with the surface of the road. It will be noted that member 28 can be disposed at different points alongthe chain 27, the lower portion 28 -of member 28 engaging in the angle between adjacent links and thus exerting a pull on the chain. The chain can thus either be pulled from the center or from some lateral point. It is often desirable to con-- nect the chains at some lateral point to give I operating on the side of av sloping road.

If it is desirable to move considerable dirt with the forward blades 15. they will be thus carry the dirt from the sides of the road 7 and other portions inwardly. This dirt will pass out between the inner ends of the bolts and will be distributed "as desired bythe rear blades 15. If a long: rut is to be filled up, the rear blades 15 can be disposed with their top edges directed forwardly and the dirt delivered by the front blades will thus be disposed in a rather long ridge. If it is desired to distribute the dirt more evenly. the blades 15 can be brought to a more nearly vertical position. The amount of dirt taken from the road by the forward blades can thus be nicely determined by adjustment of said blades by their levers 17.

If it is desired to move dirt to the sides of the road from the center of the road, the forward blades 15 will be swung with their top edges directed forwardly and will .move vervlittle dirt. The rear blades can then be setin vertical or rearwardly inclined positio1ra11d will thus move the dirt from the center of the road to the edges. By inclining both sets of blades rearwardly and using the extension blade 24. an uneven road can be nicely leveled, as both sets of blades move thereover. As the rear blades are supposed to move all of the dirt and not let any pass between their inner edges. one of the blades extends around the end of the other,--th'us forming a continuous dirt engaging surface. The blades can be quickly adjusted by the operator and with the varlous ad ustments a. very universal dragand road scraper is provided, and one which can "be used to take care of all operations which are necessary on the road.

It may be further noted that when the'extension 24 is used the blades 15 at the left and front of the device. and the blade 15 at the right and rear of the device can be It will also'be hoted thatthe device can be used with'one of the forward blades or one of the rearward. blades inclined backward so astohave little effect, and the blade either at the front'or rearheld in vertical position so that onlythe blades or blade at one side of the machine has a scraping or drag effect. The device is thus capable of many uses, and as stated above can take care of all necessary operations on the road surface.

From the above description it is seen that applicant has provided a very simple and efficient road drag and scraper and one having great utility for the use. intended.

It will. of course, be understood that various changes maybe made in-the form. details, arrangement and proportions of the parts, without departing from the scope of applicants invention, which. generally stated, consists in a device capable of-carrying outtheobjects above set forth, in the novel parts and combinations of parts disclosed and definedinthe appended claims.

What is claimed is: j

1. A road drag or scraper having in eo1nbination. a frame. a pair'of blades diverging forwardly toward their outer ends and separated in overlapping relation at their inner ends, means forrswmging sa1d blades about in the rear of said first mentioned blade and means for swinging said latter blades about horizontal axes and for holding said blades in various positions. i

2. The structure set forth in claim 1, and one of said latter blades having an extension at its inner end projecting past the inner end of the other blade of said bar.
