ROAD-DRAG.

Specification of Letters Patent.

Application filed November 15, 1909. Serial No. 528,234.

The object of our invention is to produce a cheaply manufactured yet very rigid and economical road drag by means of which roads may be quickly reshaped. The accompanying drawings 1llustrate our invention.

Figure 1 is a perspective from the rear of the machine, and Fig. 2 a plan.

In the drawings, 10 and 11 indicate two diagonally arranged forward drags, which, except that one is right and the other left, are identical. i'Xrranged to the rear of the drags 10 and 11 is a rear drag 12. I

The drags-1O and 11 each comprise a pan of upper frame bars 13, 13 preferably formed of angle irons arranged to have two vertical legs and two horizontallegs projected toward each other. Secured to the upper faces of the two horizontal legs of bars 13, 13 is a bar or board 13'. Arranged transversely below the bars 13, 13, one in front of the other, are two angle-iron bars 1 1, 14 having rearwardly projecting substantially horizontal legs and substantially downwardly projecting vertical legs. Secured to the horizontal leg of each bar 14:,

near one end, is bracket- 15, and secured.

to the same leg near the-opposite end, is a lever 16. The brackets 15 are conveniently formed ofa single L-shaped strip of metal pivoted, at 17, on a horizontal axis to the depending leg or one of the bars 13. The levers 16 are preferably formed of. two Lshaped'strips, as clearly shown in Fig. 1,

v and are pivoted, at 18, upon horizontal pivots, to the depending leg of an adjacent bar 13, the pivots 18 alining with the pivots 17.

qLevers 16 are connected by a connecting link 19 so that they may be moved simultaneously and oneside or member of the lever 16, secured to the rear bar-1e, is extended upwardlyto form an operating handle 21 In order to stifi'n the pivots 18;"we" arrange between said pivots and alongside the vertical leg of the adjacent angle iro'n 13, a

adapt the structure for plate or bar 22, the levers 16 lying'between the vertical leg of the adjacent bar 13 and the bar 22. Secured between bar 22 and the vertical leg of the adjacent angle iron 13, is a segment adapted to be traversed by the handle 21 and engaged by a suitable detent 2+1 in order to hold levers 16 at any desired angle relative to the bars 1'3 and thus determine the angle which the vertical legs of the transverse angle irons 14 may occupy relative to vertical planes. 1

Removably secured, by bolts 25, to the substantially vertical legs of the cross irons 14, are scraper blades 26 and the line of con.- nection between each scraper blade and its bar 11 is substantially midway between the edges of the blade so that said blades may be readily reversed both facewise and endwise, thus bringinginto action any one of the four edges of the blade. By this arrangement it is possible, when the scrapin edge of any blade has become too dull, to merely reverse the blade (either facewise or endwise) and thus bring into play a substantially sharp edge without the necessity of re-sharpening the blade. This is an important improvement as it saves verv much time and labor. u

The inner bar 13 of each of the drags 10 and 11 is pivoted at 31 to a transverse draft bar 32-to which is secured a foot board 33, the ends of which are extended outward so as to rest loosely upon the outer ends of the boards 13.

justed bodily toward and from each other to operation on roads Secured to draft bar 32 two draft chains 3%. 34:

of different widths. are the rear ends of which extend forwardly to a draft ring 35w The outer angle irons 13 of the two drags 10 and 11 have draft chains 36, 36 attached to their forward ends their forward ends are connected by a clevis 37 and pin 38 with the draft ring 35, the arrangement: being such that the chains 36' may be readily lengthened or shortened and thus permit the drags 10 and 11 to swing about the connections 31 as-pivots and change the horizontal angle of the scraper blades relative to the roadway. 7
