To all whom '21. 'n'zra z; concern:

luimvn that we, JAMES T. HAYNES lisusiu-rr Weiss, citizens of the lizuted Fit-Lites, residing at lieeues, in the county of lVoyne and State of .lllinois, have invented certain new and useful improvem-d-Grmlers; and we do hereby to foil wing to be 22, full, clear, and i u of the invention, such as iz rs'skilled in the art to which upiieiw .lllfs to umke and usev the some. ()ur iiveutiou relates to new and useful imprm'emenls in road. graders and our olieet is to provide means for loosening the surl:'- of the l4 21ll-\ftt and moving the some the center thereof.

object is to provide means for ie center to each side thereof.

ther object is to provide means or decreasing the depth to roudovsy is loosened "1 .1% of the 1. 3 at sectional view t5 seen on line 1 and Fig. l is o deta l elevation of the worm and gear employed for it winding drum used in connection our i prov d grader. llcferrii to the drmviugs in which similar reference numerals design ate corresponding parts throughout the several views, 1 in diczites the main frame, to the forward end of which is secured :1. cross head 2, to tlie'outer ends of which are p v iitolly secured beams 3 srid booms exlen g rcurwurdly from the :ross hood 3 and having pivotally secured to their rear ends, auxiliary frsunes -l. De pending from the frames l, are shanks 5, to the lower ends of which are rotatably secured cutting disks 6, which disks are adapted to engage the surface of the road-way and loosen the some, and, by setting said disks at the proper angle the soi so loosened will inclining the surface oftlie roadi which plates are adapted to move below'the beams 3 and are :idjustably secured to said beams by introducing pins 8 through the betlllb and, through openings 9 in the plates and, by providing a plurality of the openings in eech ofthe plates, the auxiliary frames may be set at various angles to the longitudinal plane of the frame 1 and, in order to provide a. slightly oval surface for the roadway, theshanks are slightly increased in length from the inner to the outer end of the auxiliary frames, this feature being best shown in Fig. v2 of the drawings. The rear ends of the beams 3 are suspended from a bury 1() by means of chains 11, the lower ends of said chains being secured to the beams, while the upper ends thereof are secured to rollers 12 onthe bar 10, said rollers being adopted to travel on the upper edge of the bar. The bar 10 extends laterally through standards 18 on the frame 1, said standards being provided with suitable slots 14, through which said bar oxtendsand, in order to support said bar and provide means for raising and lowering the auxiliary frames 4, a shaft 15 is extended vertically through a platform 16 carried by the frame 1 and is swivelly secured to the bar 10 at its longitudinal center and, by providing threads on the shaft 15 and extending the same throughzi threaded socket l? in the platform 16, the rotating of said shuft will raise and lower the ends of the beams 3 and the auxiliary frames carried thereby, a hand wheel 18 being secured to the upper end of tlie shaft, whereby the shaft may be readily operated and, by this means it will be seen that the disks may be elevated entirely outof engagement with the surface of the road-way, if desired.

The beams 3 are adapted to. be swung laterally away from the frame 1 to dispose the disks to the outer edge of the roadway or into the gutter and, inorder to hold the beams at varying distances from the frame 1, we provide any suitable form of cables or chains 19, the outer ends of which are secured to the beams 3, while the inner ends thereof are secured to a winding drum 20, so that by rotating said drum in one direction, the beams will be left free to swing away from the frames, but, when rotated in the opposite direction, the beams will be drawn towards the frame.

The upper end of the drum 20 is extended through the platform 16 and is provided with a gear 21, with which meshes a worm 22 on a shaft 23, said shaft being preferably inclined and the rear end thereof brou ht into juxtaposition to a seat 2e on the p atform 16, whereby the hand wheel 25, on the rear end f the shaft 23, may be readily reached by the operator. The forward end of the shaft 23 is rotatably mounted in a bearing 26, while the rear end thereof is similarlymounted in a standard 27 and, in order to prevent rotation of the drum, whereby the v cables will become loosened and the beams permitted to spread apart/a latch 28 is pivotally secured to the standard 27 and in position to engage a ratchet wheel 29 on the shaft 23.

- In order to pack the surface of the roadwa after the same has been loosened by the dis and moved to the highest part or center of the road-way, rollers 30 are provided,

which are preferably secured to the rear end of the frame 1 and the faces of said rollers are also preferably curved to conform to the curvature of the surface of the road-'wa and it will be clearly understood that whi e we have shown but two of the rollers, any number of the same may be placed in position in the rear of the disks.

The graderis adapted to be tpropelled in any suitable manner, but prefera ly by means of a traction engine or similar device and, when so propelled, the cross bar 2 is hitched to the engine and the grader caused to travel in the rear of the engine and, by suspendiru the disks from the beamsS, the gutters a longside the road-way may be reached by the disks and, at the" same time, retain the engine in the center of the road-way.

It will be further understood that where the surface of the road-wa is in a softened state, anysuitable form of lade may be employed for moving the soil to the center'of the roadway instead of the disks. It will likewise be seenthat the disks may be'reversed and used forditching purposes, the disks loosening the soil. and moving it to each side of the path of the grader and, when the grader is so used, the rollers are to be dispensed with.

It will thus be seen that we have provided a very efiicient and economical form of grader and one wherein the loosened soil from the outer edges of the road-waymay be readil moved to the center of theroad-way and toroughly packed and it will likewise be seen that the surface of the road-way will be gradually curved from the center to the I outer edges thereof. It w likewise be seen that the parts of the gra er can be quickly and'easlly operated to lift. the disks from enthe frame.
