ROAD-DRAG.

Application filed July 31, 1915.

To all whom it may concern:

Be it known that I, HILDOR ERIoKsoN, a citizen of the United States, residing at Palmer, in the county of Pocahontas and State of Iowa, have invented a new and useful Road-Drag, of which the following is a specification.

This invention relates to an improvement in road drags, and the object is to provide a frame having a plurality of blades extend ing outwardly from'the sides thereof, and means for adjusting the blades to change the angle of the blades to suit the conditions in the working of the road.

A further object is in the provision of gutter or ditch cleaners for the purpose of cleaning the ditches at the same time that the road is being scraped.

A still further object is in the provision of means for conveying the drag from one locality to another by means of wheels or rollers, which are connected to the drag and normally held at an elevation, sothat. they will not interfere with the drag blades when they are to be used, but which are capable of being lowered for elevating the blades when it is desired to remove the drag from one destination to another without the blades coming in contact with the road surface.

-The invention consists of certain novel features of construction and combinations of parts, which will be hereinafter described and pointed out in the claims.

It will be evident that many slight changes may be made in the form and arrangement of the several parts to be described, without departing from the spirit and scope of the invention, and hence I do not wish to be limited to the exact construction herein set forth.

In the accompanying drawings,-Figure 1 is a top plan view of the invention, the dotted lines indicating the position assumed by the blades in crowning the road. Fig. 2 is a view in end elevation. Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 1. Fig. 1 is a sectional view on the line H of Fig. 1. Fig. 5 is a detail view partly in section of the clip and pulley of the draft beam, illustrating the manner of passing the chain around the pulley.

Serial No. 43,011.

The frame of the drag, which is preferably made rectangular, consists of longitudmal channel or I beams A which are connected together by cross-bars 1-1 and diagonal bars 2. Thecross bars 1, beams and the diagonal bars 2, afford a strong and rigid frame. Pivotally connected to the lower surfaces of the beams A are the inner terminals ofthe transverse or channel bars 3. These bars are preferably made U- shaped, the smooth surface projecting toward the forward end of the machine, and the right-angular flanges 4 extending rearwardly. The upper fianges 4 of the channel bars 3 are connected to the beams A by means of bolts 5 and nuts 6. Mounted on the bars 3, and near their outer terminals,

are longitudinal channel beams B. The beams B are connected to the upper flanges of the transverse bars 3 by means of bolts 7 and nuts 8. Braces 9 are connected to the lower flanges 1 of the bars 3 by bolts 10 and nuts 1.1. The upper terminals of the braces 9 are connected to the undersides of the beams A and B by means of bolts 12 and nuts 13. These braces strengthen the transverse bars 3 along their lower edges where the greatest strain is imparted to the bars.

Connected to the front face of each bar 3 is a blade 14, by means of bolts 15 and nuts 16. The blades 14: project below the lower terminals of the bars 3. Mounted centrally on each bar A is a vertical shaft 17. The shaft passes'through an upper flange 18 of the bar A, and has its lower terminal reduced to fit into an opening 19 in the lower flange 20 of the bar. A washer 21 is mounted upon the shaft beneath the upper flange 18, and a pin 22 passes through the shaft beneath the washer for fastening the shaft to the beam.

Mounted upon the shaft 17 andabove the flange 18 of the beam A, is a sprocket wheel 23 which is fixed to and rotatable with the shaft 17 Connected to the outer terminals of each beam B is 'a chain 24, which chain passes around the sprocket wheel 23 of the shaft 17 Upon the rotation of the shafts 17 the chains 24. will be caused to travel in one direction or another for shifting the transverse bars 3 at an angle to the beams A. Longitudinal plates are mounted upon bars 1 connected to the beams A. A ratchet wheel 27 is fixed to each shaft 17 and located above the plates 25. A foot pedal 28 is fulcrumed on the plates 25, and a terminal of each foot pedal .28 is adapted to engage the teeth of the ratchet wheels 27 for holding the shafts 17 against rotation, whereby the transverse bars 3 may be held at right angles to the beams A, or at any angle in a horizontal plane which the occas1on may demand.

The two shafts 17 and chains 24 permit the bars 3 on each side of the frame to be maintained at the same angle with respect to the frame or beams A, or one set of bars may be held at a different angle from the other set, or the bars on the opposite side of the frame. Connected near each end of the beams A and B are bell crank levers 29. Journaled in the lower terminals of the bell crank levers are rollers or wheels 30. A link 31 is connected to the levers 29 of each beam. A hand lever 32 is pivotally connected to each beam A and B, projects upwardly from the frame, as shown in Figs. 2 and 3, for ready access and is pivotally connected to the link 31 of each beam by a pin 33. A toothed segment 34 is connected to each beam, and the teeth of the segment are engaged by pawls 35 which are connected to the hand grip 36 of the lever by links 37. Upon the actuation of the levers 32 the wheels 30 can be moved to a position for raising the blades 14 above the I road surface, or the wheels can be moved to a position so that the blades will be moved into engagement with the road surface and the wheels above the road surface. WVhen the wheels are brought into engagement with the road surface the drag can be moved from one locality to another, across bridges and the like.

W hen it is desired to cross a bridge which may be of narrow construction, the bars 3 can be swung or shifted at such an angle with respect to the beams .A, for instance, that indicated by dotted lines in Fig. 1, so that the drag can be conducted across the bridge without the necessity of disconnecting any of the parts of the drag.

Hinged to the outer surfaces, and near the lower terminals of the beams B, are bars 38 which are provided with blades 39, These bars 38 and blades 39 are constructed and connected together in the same manner as the bars 3. A chain 40 is connected to an eye 41, at the outer terminal of each bar 38, and a hook 42 on the other terminal of the chain is adapted to engage an eye 43 on the bar of the beam B for affording rigidity to the bar 38 during the scraping operation. The bars 38 are intended to scrape or clean the gutters or ditches along the sides of the road, and the angle of these bars can be changed by simply passing the hook 42 through the eye 43 and causing the hook to engage a link of the chain or the eye 41. Nhenthe hooks 42 are passed through the eye 4:3 and engage the eyes 41, the bars 38 will be swung practically to their limit of movement toward the beams B.

A draft beam 45 is provided with clips 46 at its outer terminals, and journaled in the clips are pulleys 47. Chains 48 are connected to the beams A and B and each chain passes around a pulley 47. This flexible connection between the drag and the draft beam permits the drag frame or beams A to always be maintained in the line of draft, whereas the bars 3 and 38 may be at an angle to the line of draft. The connection of the bars 3 with the beams A and B is such that the bars may be swung or shifted to an angle with respect to the beams without changing the parallelism of the beams A and B. The beams B may be moved closer to the beams A, but they will always be maintained in a parallel relation, and the bars 3 will always be maintained parallel to each other. The chains or flexible connections 24 permit the bars on either side I of the frame to be shifted at an angle with respect to the frame, regardless of the angle of the other set of bars located on the opposite side of the frame.

From the foregoing it will be seen that I have provided a drag which can be constructed and assembled at a small cost, and which is simple in its operation. The scraper blades can. be arranged at any angle to suit the requirements in the formation of the road surface. When the road is to be crowned the bars 3 and the plates 14 are swung at an angle, other than a right angle, with respect to the beams A.
