Be it known that I, FRANKE;T$;- a-0iti zen of the United States, residing at" Indianapolis, in the county ofLMarion and State of thereof, the-invention having reference particularly to adjustable'drags of the abovementioned character. V

Objects of the inventionareto provide a relatively light weight strong drag adapted to be constructed at inoderate'expensd'and to provide a drag of sim 1e constructionthat may be adjusted'leadl y so -asto -o erat'e equally-well on either hard "or relative y soft roads-surfaced either with. earth or w ith" gravelw a The invention consists an improved drag=comprising an angle iiron frame, scrapingblades of improved.- construction, connected iii a novelmanner to the frame so, as

.to be adjustable relatively thereto, and imroved adjustin and controlling mechanism or the blades, t invention consisting fur? ther in the parts and combinations and'ar f a body part of the lever m", the atter be ng prorangement's of parts as herein terparticw larly described and defined in 31c appended v Referring to the drawings Figure 1 isaperspective view-of the improved drag ;'Fig.'- 2,

A pair of 3 arms t and t are rigidly secured on the tops of the flanges j and 3 respectively, and'the tops of the arinsl are connected by a coupling rod if, the arms being connected to the beam 6 by pivots v and 2).

thus described the invention, what as new is.

- 1;. Aroad drag including a frame-comprising? two end beams, two main'beams be- '35 tween the. end-beams,- an angle brace attached to the forward. end portion of one of theend beams and to the rear end portion of one of the main beams, an angle brace attached to the forward end portion of the other one'ofthe end'beams and to the rear end portion of the other one of the main beams, and a platform extending across the tops of the main beams and secured to the end beams, with a plurality of blades connected to the beams;

2. A road drag including a frame comprising two end beams and two main beams between the end beams, each end beam having a plurality ofv arms pivoted thereto, a pinrality of blades each attached to a plurality of the arms, an' arm pivoted to the two-main ver and pivoted also to the arm that is piv-l ote'd to the main beams, a curved latch bar beams and attached to one of the blades, a lever pivoted to. the two main beams and attached to another one of the blades, a coupling rod pivoted at one end thereof to the leattached to the two main beams, and a latch mounted on the lever to engage the latch bar.

8. Aroad drag including two end beams having each an angle brace attached thereto osition,,being designed toiengage'eith'er lin flatwise'between th'e ver and said arms extending up beyond the beams, a plurality of blades one of which is attached to a plurality of the arms and an- "other one of which is attached to the lever and also to a plurality of the arms, a coupling rod pivoted to the lever and also to the arm that is pivoted to the two main beams, said rod bein arranged in a plane above the main beams, a coupling rod connected to an arm "of one of the blades and also to an arm' of another one of the blades above the plane ofthe beams, a coupling rod connected to an-. other. arm of one of the blades'and also to an: other arm of another one of the blades above the plane of the beams, and a draft chain connected with the two end beams.

4. In a road drag, the combination of a frame comprising a plurality of main beams, a plurality of end beams that are longer than the main beams, an angle brace attached to the forward end of one of the end beams and to the rear end of one of" the main beams, an angle brace attached to the forward end of the other end beam, and to the rear end of the other main beam, and a platform extending across the middle portions of the plurality of beams and secured thereto, with draftlinks connected to the forward ends of the end beams near the angle braces, and blades connected with the beams.

5. In a road drag, the combination. of a plurality of end beams having each a draft rod connected thereto, a chain connected to the draft rods, a each a flange at the top thereof and each flange having a plurality of arms secured thereto, one of the flanges having a lever secured thereto that has a latch thereon, a plurality of main beams, a pivot connecting the lever to the main'beams, pivots connecting one of the arms to the main beams, pivots connecting the remaining arms to the end beams, coupling rods connecting one of the arms with the lever, coupling rods connecting the remaining arms of one blade with the arms of another blade, and a latch bar secured to the main beams to be engaged by the latch.
