ROAD-DRAG.

Specification of Letters Patent.

Patented'ripr. 21, 1914.

Application filed July 24, 1912. Serial No. 711,297.

17 0 all whom it may con cern Be it known that I, PERRY G. DOWELL, a

citizen of the United States, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Road-Drags, of which the following is a specification.

This invention relates to road drags, and has for one of its objects to provide a device of the above character which may be cheaply and durably constructed.

The drag forming the subject matter of the present invention, comprises a plurality of corrugated plates or sections which operate upon the ground for leveling the latter, and suitable means for connecting or securing the sections or plates together.

The invention further provides a scraper bar or member disposed in advance of the corrugated plates, said bar projecting downwardly below the operating surfaces of said corrugated plates.

With the above and other objects in view, reference is to be had to the following description and to the accompanying drawings wherein,

Figure 1 is a top plan view of a drag constructed in accordance with the present invention; Fig. 2 is a front elevation thereof; Fig. 3 is a side elevation of the drag; Fig. 1 is a detailed perspective view of one of the plates or sections of which the drag is constructed; Fig. 5 is a view of a drag comprised of curved plates not corrugated; and Fig. 6 is a similar view of a drag in which a single curved plate is employed in lieu of the several plates.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

A, road drag constructed in accordance with the present invention, comprises a plurality of plates or sections secured by spaced angle iron members and a scraper bar secured to the sections or plates by short angle iron members whereby said bar is rigidly fastened to the first plate, and disposed in advance thereof for leveling the ground, previous to the action of the plates on the latter. Further reinforcement of the structure is obtained by securing the clevis fastoning plates to the first section, and fastening the clevis through the clevis fastening plate and the scraper bar, as will be hereinafter disclosed.

The plates or sections 1 are of corrugated material, and the central portions thereof are bent or curved downwardly, as at 2, the edges of the plates lying in the same plane, and provided with apertures or openings 3, whereby he several plates may be secured to the angle iron frame members t in any desirable manner. By having the plates 1 corrugated, the operating surfaces 2 wiich operate upon the ground, not only are adapted to yield, but such corrugations stiffening the plates.

In advance of the first plate 1, is mounted the scraper bar 5, the latter being preferably rigidly secured to the first plate by the short angle iron extensions or splice bars 6 bolted or otherwise detachably fastened to the frame angle irons 4, and said plate 1. This scraper bar 5 is preferably constructed from angle iron, the lower or scraping edge 5 eX- tending below the plane of the operating surfaces 2 for cutting or scraping the ground into a crude level condition, previous to the final action on the ground by the operating surfaces 2.

The draft rigging employed in moving the drag, is fastened to the pair of clevises 7, supported by the scraper bar 5. A clevis fastening or mounting plate 8 1s fastened to the first plate 1, while its forward terminal is provided with an aperture adapted to register with a second opening in the scraper bar 5, through which the bolt may pass for fastening the clevis 7 to the drag. From the foregoing, it will be observed that any pull on the clevises 7, will not tend to strain or pull the scraper bar 5 from the sections at the point of the mounting of the clevises, since such action is prevented by the plates 8, which are rigidly fixed on the adjacent plate 1. I

A road drag constructed in accordance with the above description, requires simply a plurality of corrugated plates or sections,

and a plurality of angle iron members of plates or drag members Without corrugations. The plates in Fig. 5 are mounted in a manner similar to the plates in Fig. 1. In Fig. 6 the several plates 1 of Figs. 1 and 5 are replaced by a single plate 1 comprising several curved surfaces to operate upon the ground said plate being fastened at the upper curved portions 1 to the angle irons by rivets or other suitable means.

Having thus fully described my inven tion, What is claimed as new is:

In a drag the combination of a scraper bar of angle material having a pendent flange and a horizontal flange, splice bars spaced longitudinally of and connected to the horizontal flange and extending inwardly therefrom, a plate extending longitudinally of the scraper bar in the rear thereof and having a longitudinal edge di rected toward the scraper bar, said plate having a longitudinal depression intermediate its edges and having its edge portions fixed to the splice bars a series of similar plates arranged edge to edge at the rear of the first plate, and frame bars fixed to the splice bars and extending transversely of and being connected to the last named plates.

In testimony whereof I affix my signature in presence of two Witnesses.
