EDWARD M. GRTOIT. F SANDSTONE, MINNESOTA.

ROAD DRAG.

Application filed February 7, 1822.

To all whom it may concern:

Be it known that l, EDWARD M. OnToN, a citizen of the United States, residing at Sandstone, in the county of Pine and State 6 of Minnesota, have invented certain new and useful Improvements in Road Drags, of which the following is a specification.

This invention relates to road drags, and the main object is to provide a simple, ef-

10 ficient and practical drag particularly adaptable for use in connection with common types of road scrapers and other road machinery. Further objects will be disclosed in the course of the following specification and are illustrated in the accompanying drawing, wherein:

Fig. 1 is a top or plan view of a device embodying my invention.

Fig. 2 is a detail sectional view on the so line 2-2 in Fig. 1.

Fig. 3 is an enlarged fractional detail, as seen when looking in the direction of the arrow A in Fig. 1.

Referring to the drawing by reference characters, B designates a road scraper blade of any common and well known con struction, secured by beams C to tl'lBmZtClllDG or vehicle (not shown) carrying it. Pivotally secured as at D to the beams C is a pair of rearwardly extending angle-iron beams E to the front ends of which is secured an angle iron drag beam F. A secondary pair of longitudinal beams G are pivotally secured to thebeams E, as at H, and have a cross beam I (similar to F) secured at their rear ends. The vertical flanges of the beams G and E engage one against the other, as shown in Fig. 1, and the vertical flanges of the beams F and I extend downward from the front edges of their horizontal flanges.

Spacing blocks J are interposed between the rear ends of the beams G E and their respective cross beams l and F, the object being to permit said latter beams to ride over rough roads in such a manner that either may fall in relatively higher or lower position than the other (see Fi 2). At the rear ends of each of the beams I and F is provided a rigid prong K, which, as the dirt works to the outer ends of said beams, pass through said dirt with a tendency to remove rocks or other lumpy obstacles therefrom, and push them farther out to the side of the road.

serial No. 534,761.

In the event that the angle of the scraper blade is adjusted to suit changing road conditions it will be obvious that the angle of the beams f, F to the road will be correspondingly changed as the beams E and G are always retained in parallel positions and the bolts which connect said beams to the long cross beams I, F act as pivots.

It is further understood that suitable modifications may be made in the design and structural features of this device, provided, however that such modifications come within the spirit and scope of the appended claims.

Having now therefore fully shown and described my invention, what I claim to be new and desire to protect by Letters Patent is:

1. A road drag consisting of a primary pair of parallel longitudinally arranged draft beams pivotally secured at their front end to a means for drawing the drag and having a cross beam at their rear-ends, a secondary pair of draft beams pivotally secured to the first mentioned pair of draft beams, and having a second cross beam arranged at their rear ends.

2. A road drag consisting of a primary pair of parallel longitudinally arranged draft beams pivotally secured at their front end to a means for drawing the drag and having a cross beam at their rear ends, a secondary pair of draft beams pivotally secured to the first mentioned pair of draft beams, and having a second cross beam arranged at their rear ends, said primary and secondary draft beams having vertical flanges engageable against each other.

3. In a road drag, a primary pair of draft beams, a secondary pair of draft beams pivotally secured thereto, cross beams secured to said draft beams, and spacers interposed between the cross beams and the draft beams.

l. In a road drag, a primary pair of angle iron draft beams, a secondary pair of angle iron draft beams arranged parallel with but extending rearward of the primary beams, said primary and secondary beams having vertical flanges pivotally secured together, and cross beams secured to and in angular relation with respect to the draft beams.

In testimony whereof I affix my signature.

EDWARD M. ORTON.
