ROAD GRADER AND DRAG.

Specification of Letters Patent. 7

Patented Dec. 20, 1910.

Application filed February 24, 1910. Serial No. 545,683.

To all-whom it may concern:

Be it known that we, THOMAS I. SwAs- ERTY and ARTHUR L. Lown, citizensof the United States, residing at Fontana, in the county of Miami and State of Kansas, have invented certain new and useful Improvements in Road Graders and Drags, of which the following is a specification.

Our invention relates to road working machines and particularly to that type of road Working machine which is dragged over the surface of the road and which acts to level and grade the same, the obj eet of my invention being to provide a grader and drag of this character in which the scraping beam may be set to any desired inclination with the line of draft, and wherein the line of draft shall always come opposite to the longitudinal axis of the scraper so that the same will drag evenly.

A further object is to provide means whereby the scraper as a whole, including the scraping beam may be raised at one or both ends, as desired, so as to give an inclination to the scraping beam or lift it entirely from the surface of the road.

A further object is to provide a very simple scraper of this type, easily constructed, cheaply made, not liable to get out of order, and which has been found to be thoroughly effective in practice.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which Figure 1 is a perspective view of our improved drag and scraper in operation. Fig. 2 is a plan view thereof showing the scraperbeam in an angularly adjusted position. Figs. 3 and A are front views of our scraper showing the scraper-beam at various inclinations. Fig. 5 is an entire view showing the scraper-beam as elevated at both ends above the road.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

Referring to these drawings the numeral 2 designates the scraper-beam which extends transversely of the apparatus and is provided on the lower portion of its front face with an outwardly and downwardly turned scraping blade 3. The scraper-beam is pivoted to opposed rearwardly extending parallel side-beams 4. WVhile we do not wish to limit ourselves to any specific manner of connecting the scraper-beam with the sidebeams, a very simple and effective construction is that shown in the drawing wherein the inside face of the scraper-beam is pro-- vided with the two rearwardly extending U-shaped clips 5 which receive the forward ends of the side-beams A, and through which pass the pintles 6.

The rear ends of the side-beams 4 are provided with sharp edged runners 7 which preferably may be made of metal and attached to the outer faces of the side-beams l. The side-beams are slightly less in depth than the scraper-beam 2, and hence the under faces of the side-beams will not con tact with the earth, but the side-beams will be normally supported upon the runners 7 Connecting the beams 4:, are the parallel links 8 which are pivoted at their extremities to the beams 4. It will thus be seen that the beams may be turned from a position at right angles with the scraper-beam 2 to an acute angle therewith.

In order to hold the scraper-beam in any desired angular relation to the beams 45, and therefore to the line of draft we provide the scraper-beam 2 with the rearwardly projecting arm 9. This arm 9 may be formed in any manner, and is rigidly attached to the inside face of the scraper-beam as by means of a dowel 10 which projects into a mortise in the scraper-beam. The forward end of the arm 9 is widened so as to give it a good bearing upon the scraper-beam. The rearward end of the arm 9 is reduced to form a handle whereby the angular direction of the scraper-beam may be changed if desired. 7

In order to hold the scraper-beam in any desired angular relation with the side-beams we form the arm 9 with a plurality of longitudinally extending holes 11 and provide a series of holes 12 111 the rearmost link 8, the holes in the arm 9 and the link 8 being so relatively arranged that when the scraper-beam is turned to any desired angle with the side-beams 4, one of the holes 12 will come into register with one of the holes 11 in the arm 9. A pin, bolt, or other suitable fastening device is passed down through the holes 11 and 12, and when so fastened,

the side-beams are held in rigid relation to the scraper-beam.

A flexible draft connection 13 is attached at one end to the rear end of that one of the side-beams 4 which is opposite to the arm 9. 'l he connection then passes diagonally across the scraper and through a hole 14 in the scraper-beam adjacent to the end of the arm 9. The flexible connection passes through an opening 16 at its other extremity and is then attached to the scraper-beam or formed so that it cannot pull through the opening.

A shackle 15 is provided upon the flexible connection at such position that when the side-beams 4 are at right angles to the scraper-beam 2, the shackle will be exactly opposite the center of the scraper. VVhitlletrees 17 may be of course attached to the shackle, whereby the scraper may be dragged over the ground.

In order to raise either one or both ends of the scraper from the ground, we provide the lifting levers 18 which are pivoted to the side-pieces or beams 4: at their forward ends. The rounded ends of these levers when turned into a vertical position project below the side-pieces 4t, so that the scraper is then supported upon the runners 7, and upon the curved, or rounded ends of the levers 18, the scraper being of course elevated somewhat above the ground, depending upon the elevation of the levers 18. It will be observed that when one of these levers is turned to an angular relation to its sidebeam 4, and the other is parallel to the side beam, the scraper will be raised on one side and the scraper blade will therefore be inclined, as shown in Figs. 3 to 5.

Any suitable means may be provided for holding the levers 18 in their adjusted po sition, but we have shown arcuate toothed racks 20, the levers 18- being each provided with hand operating devices for engaging said racks. It is therefore noted that by reason of the fact that the flexible connection 13 passes freely through the opening 1 1 and is attached at its end to the rear end of one of the side-beams a, and the shackle 15 will always be exactly opposite to the middle line of the scraper, or in line with the line of the draft. lVhen the scraper is brought to the position shown in Fig. 2 with the scraper-beam inclined to the line of draft, the draft animals will have precisely the same relative position in regard to the scraper as they have when the scraper was so adjusted that the scraper-beam is transverse, or at right angles to the line of draft.

The operation of our invention is obvious from what has gone before. A scraper of this character may be used either as a drag for leveling roads and cutting down hummocks and ruts, or a scraper for grading the surface of the road, and for forcing the dirt to one side of the road. By reason of the levers 18 and their ability to adjust the level of the scraper, the scraping device may be used for giving the proper inclination to the crown of a read.

It will be seen that our invention comprehends only very simple elements, msily manufactured, easily repaired, and of such relatively simple and heavy construction that itwill not be easily broken or damaged.

Having thus described the invention what is claimed as new is 1. A drag and scraper including a scraper-beam, a rearwardly extending sidepiece pivoted to the scraper-beam, means for adjusting the angular relation of the scraper-beam and the sidebeam, and a flexible connection attached at one end to the rear end of the side-beam then passing freely through the scraper-beam and attached at its other end to the end of the scraperbeam.

2.
