ROAD-DRAG.

Specification of Letters Patent.

iatented Mar. 15, 1921;

To ZZ wlw/m t may concer/n:

Be it known that we, lViLLiiiii H. BAn'i'ELL and HENRY C. LonsoH, citizens of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented' certain new and useful Improvements in Road-Drags, of which the following is a specification.

This invention relates to newA and useful improvements in road drags, and the 'primary object of the invention is to provide a road drag' of this character, provided with iiieans whereby thel drag bars maybe capable of various adjustments as is obvious.

Another object of the invention is to provide a road drag of this character', formed `of oppositely disposed scraper sections, provided with reversible angularly adjustable drag bars, said sections being capable of various adjustments with respect to each other, either to scrape the dirt toward the center' of the road, or to either side thei'eof.

A further object of the invention is to provide a device of this character, which is easily and simply constructed, inexpensive to manufacture, and one which will be very eiiicient in operation.

lith these and numerous other objects in view, our invention consists of the novel features of construction, combination and arrangement of parts which will be herein referred to, and more particularly pointed out in the speciiication and claim.

In the accompanying drawings:

Figure 1 is a top plan View of theroad drag; j Y

Fig. 2 is an end elevation thereof;

Fig. 3 is a detail perspective view of one of the connecting means between the drag bars, and connecting rods; and

Fig. 4 are diagrammatic views of various positions in which the scraper sections may be placed.

In describing our invention, we shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views.

The drag` is formed of two scraper sections designated by the numerals 1V and 2, which are each formed of a plurality of parallel drag bars 3. The scraper section 1 has the parallel drag` bars 3 connected intermediate, the ends of the same by spaced parallel connecting rods 4, preferably formed of angle iron, and end connecting rods 5, which are bent, as clearly shown in Fig. 1 of the draw# ed to rock, when the rocking means are ap-' plied as will beV hereinafter more fully described. The opposite parallel connecting rods 4 are connected with the end connecting rods 5, by ycross connected link membersy 9 and 10. Y Y j .Y 'Y

Projecting upwardly between the spaced connecting rods 4, that are kcentrally disposed with respect to the scraper section 1, are arinsr11, having feet 12 on their lowerends secured to the angle Airon 6, said arms 11 extending above the arms 8, and having their upper ends connectedby a transversely extending bar 12. The bar 12 has its rear extremity connected to a pivoted lever V13 mounted on the tapered section, said lever being adapted to be locked in various adjusted positions by means of lan arcuate rack member 14, provided with a vplurality of apertures, adapted for alinement with an aperture througlitlie lever, a pin insertible Y therethrough to hold the lever in various adjusted positions. in position on the rear end `of the scraper section l, by projecting arms 15, as clearly shown in Fig. 2 of the drawings.

The scraper section 2 is substantially similar to the section 1, except that Vthe center connecting rods which are designated by the numeral 16 are curved to conform to the therewith are similar to the means employed on the sections 1, and additional descriptiony thereof andthe other parts of this scraper" The rack 14-is securedVVV curvature of the outer connectingrods 17 The lever and locking means associated with the power used to pull the drag and by varying the length of the chains the va rious adjustments suggested in Fig. f1 may be obtained, the link 18 maintaining the sections in properly spaced relation.

In operation, the drag bars 3 are normally disposed upright, as shown in Figs. l and 2 of the drawings, when it is desired to shift the same, the locking pin that locks theV lever to the rack 14 is removed, and the lever 13 swung `in either direction. This will rock the bars 3, as the same are connected by the bar 12, arms 11, and angle iron G to the dra@ bars.

llihen the desired adjustment has been made, the lever 13,is locked in position, by inserting the locking pin through the alining apertures, and the drag bars will be locked in various angular-ly adjusted positions. The connected rods 1l and 5,and 16 and 17 of the sections, are held rigid7 above the` swingable bars 3, and the draft'connections of the device are made to these trames.

From the above description taken in connection with the accompanying drawings, it is thought that a clear and comprehensive understanding of the construction, operation, and advantages of. our invention may be had, and while we have shown and .described the device as embodying a speciiic structure, we desire that it be understood that such changes may be made in said structure as do not depart from the spirit and scope of the invention as claimed.

Having fully described our invention what we claim as new, and desire to secure by Letters Patent is:

In a road drag, scraper sections, said sections comprisingA a plurality of parallel scraper bars, angle bars connected to the scraper bars, upstanding arms rigidly connected with the angle bars angularly bent connecting rods connecting the upper termi nals of said arms, relatively long arms connected medially with the angle bars, two of said angularly bent connecting rods being arranged on opposite sides of the relatively long arms, said sections being movable into alinement or various angular positions, an

adjustable spacing member connecting the inner angu'larly bent connecting rods in `proximity to the rear scraper bars, and flexible d .'a'ft members connected with the opposite terminals ot each, section for anglingor straightening the sections by the pull ot the draft animals.

In testimony whereof, we aiiix our signatures hereto.

WILLIAM Ifl. BARTELL. HENRY C. LOESCH.
