ROAD-DRAG.

Specification of Letters Patent.

Patented May 1, 1917.

Application filed November 27, 1916. Serial No. 133,608.

To all whom it may concern:

Be it known that I, NICOLAI J. BERGE, a citizen of the United States, and resident of Deerfield, county of Dane, and State of WViscousin, have invented certain new and useful Improvements in Road-Drags, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to an implement for leveling road beds, its object being to provide efiicient means for loosening the surface material of the road, for deflecting stones to the side of the road bed, and for scraping the remaining loosened material toward the center of the road bed.

The invention consists of a device such as hereinafter described and illustrated in the accompanying drawings, in which Figure 1 is a plan view of the drag,

Fig. 2 is a side view thereof,

Fig. 3 is a sectional view on the line 3-3 of Fig. 1, and

Fig. 4 is a detail front view.

The drag comprises a pair of bars, 10-11, each preferably formed of wood and faced at each side with metal plates 12-13, these bars being backwardly inclined from the axis of the device. It also comprises a pair of bars 1%15 rigidly attached to the outer ends of the first named bars and extending backwardly and inclined inwardly, such bars also being preferably of wood with metal facing. The inner ends of all of the bars are hinged to an axial rod 16 to permit a vertical fiexure.

The bars l011 are provided with downwardly projecting cutting teeth for loosening the surface material of the road bed. Such teeth 17 are preferably of the form shown in Figs. 3 and 1, each being provided with a pair of upstanding lugs 1819 for engaging the front and rear faces of the bar and apertured to receive a securing bolt 20. The teeth are brought down to a cutting edge 21 for facilitating their entry into the material to be loosened and preferably they are cut away at one side, as shown at.22, to provide a clearance for such small stones as Copies of it may be desirable to retain upon the road bed. The front faces of the bars 10-11 being smooth permit the larger stones to slide OH to the side of the road bed and the backward inclination of the bars insures this action.

The bars 1t15 are without teeth and serve to force the loosened material inwardly toward the center of the road bed, their inner faces being smooth to facilitate this movement, thereby restoring the road bed to its crowned form, the bottom faces of the rearward portions of the bars 1-15 inclining upwardly, as shown at 23, thus permitting some of the material to escape and giving the more even distribution of it to insure the proper crowning. The hinge members, 2125, by means of which the rearward ends of the bars 14.'-1.5 are attached to the rod 16, extend laterally from this rod a sufficient distance to space the rear ends of the scraper bars to provide a passage for the material which has been brought to the center, these hinge members being disposed at the top of the bars, thus allow ample clearance for the material.

For the purpose of attaching a team to the device it is provided with a pair of hounds 26-27, attached to the bars 1011, some distance from their inner ends and to a ring 28 with which the whifile tree 29 is connected.

The hinging of the drag and scraper bars to the rod 16 adapts the device for use on road beds having more or less crown surfaces and also facilitates the action of the device over road beds which are exceedingly rough and which must be gone over more than once.

I claim as my invention,

In a road drag, in combination, an axial member, a pair of backwardly inclined toothed bars and a pair of scraper bars extending from the outer ends of the toothed bars backwardly to the axial member, all of said bars being hinged for vertical flexure at their inner ends.
