ROAD-DRAG.

Specification of Letters Patent.

Patented Jan. 19, 1909'.

Application filed May 11, 1908: Serial No. 432,110:

To all whom it may concern:

Be it known that I, VILLIAM A. TRAVER, of Weedsport, in the county of Cayuga, in the State of' New York, have invented new andusefulImprovements in Road-Drags, of which the following, taken in connection with the accompanying drawings, is a full, clear, and eX-act description.

This invention relates to certain improvements in road'l drags and is equally useful in leveling up and padding race tracks and also in making new roads and crowning or truing up old roads.

My main object isto produce a practically all steel, comparatively light yet highly efficientf and durable road scraper'which may be manufactured at a comparatively small costi and? in which the scraper blades are interchangeable andr reversible'k to permit the use of either edge next to the ground when 'one edge becomesl worn or otherwise impaired Another object is to provide the normal top side ofthedragor scraper with suitable shoes or runnersproject-ing beyond the plane ofthe longitudinal edges of the scraper bladesso that the entire machine may be inverted and easily drawn longitudinally along the ground or pavement over rail road? tracks and other obstacles with but little resistance.

A1 further object is to provide the dragy with opposite parallel scraper blades spacedv some distance apart and curved longitudinally forming opposite concavo-convex scrapers, either sidel of which may be presented inY advance of the other to throw the dirt from the centerof theroad outward or from the sides inward.

A still further object` is to connect the opposite ends ofr4 either side'of the drag by a chain or similar draft devicer to which a draft hookor similar connection may be attached` at' any point either centrally when it is desired to level race tracks andsimilar courses or near one endfof the other whenfit is desired to bring the maximum draft or power near suchend? asin making gutters or crowning the road bed.

@ther objects and useswill be brought out inthe followingvv description.

In the drawings-Figure l is-a top plan ofaroad drag embodyingthe various features off my invention' showing the 'draft' device attached to theconcaveside Figs. 2 and 3 are enlarged sectional views taken respectively on lines 2 2 and 3 3', Fi s 1. Fig. et 1s a side'elevation of one end o the drag 1n an inverted position showlng the runners in contact' with the ground. Fig. 5y 1s a detail elevationl of the draft hook andlink of the draft chain embraced thereby- This drag comprises essentially a steel frame composed of opposite parallel side piecesy -l-, opposite parallel endf pieces -f2-, corner braces --3ed and.I steel scraper blades ll-.

The side pieces -1- preferably consist off steel anglel bars of' similar length curved angle bars parallel with each other and' of a1 length substantially the distance between the side bars-4*, with their lower flanges dis posed in ai horizontal position projecting t'oward each other and their upper fianges projecting from the outer edges thereof The braces 3'- are alsoformed of steel and are secured to thc'top/` faces of the bars land under sidesoff' thelbars2- by suitable fastening means as rivets or bolts -5--, said braces being locatedfat the inner'corners or junctions of the side/bars with the end bars as best seen in Fig: l.

The opposite ends of the side bars rest upon and are secured'to the-top faces-of the adjacent portions of the braces--3 which are, therefore, interposed between said side and end bars and serve to reinforced and stiften the frame against any strains to which it may be subjected, theV end bars -2- being located a short distance inwardly from the ends ofE the side bars.-

The blades -lare secured'to the outer sides of the side bars-L- by suitableJ fastoning means as bolts -G- and are'ofA sub-y stantially the same length and' curvature as said' side bars' but of greater vertical depth so as to extend some distances above and beneath the side bars to whichthey are securedv as best shown lnFigs. 2 and 3, said blades being also made of steel capable of withstanding the strains to which they are subjected. These blades are removable andI interchangeable and invertible so -that when one edge becomesworn they -may be removed and inverted and interchanged from side to side and the other edges presented to the ground without disturbing the connections between the side and end bars of the main supporting frame.

It is now clear that one of the working sides of the drag is concave or curved inwardly and horizontally from end to end while the opposite working side is curved or convexed and parallel with the concave side thus permitting either side to be used according to the work required, each side being equipped with a pair of attaching elements as eyes -7- for the attachment ofV a draft chain -8- shown in Fig. 1 as connected to the concave side of the drag..

The object in employing a chain as a draft connection is to enable the draft hook as -9- to be attached at any point between the ends of the chain according to the work which it may be desired to perform, said draft hook being adapted to detachably embrace any one of the links as shown in Fig. 5. For example, when it is desired to level up race tracks or any similar plain course, the draft hook -9- may be attached to the center of the draft chain -8- and the chain attached to either the concave or convex side of the drag or if it is desired to plow a furrow for forming a gutter and to throw. the dirt toward the center of the road bed, the chains may be attached to the concave side of the drag and the draft hook attached to the chain near the side where it is desired to plow the furrow as shown in Fig. 1. On the other hand if it is desired to throw the dirt from the center of the road toward the sides the chain may be attached to the opposite or convex side of the drag in an obvious manner.

In order that the entire drag may be drawn over railroad tracks and other obstructions without meeting undue resistance, I provide the normal top of the frame with a series of in this instance four runners or shoes -lO- which are made in the form of steel straps arched upwardly at the center and secured at their ends directly to the braces -3- and outer sides of the cross bars Q- The central portions of these shoes or runners normally project some distance beyond the top of the scraper plate -tand when it is desired to transport the entire device from one locality to another, said device is inverted bringing the shoes in contact with the ground whereupon the chains may be attached to the eyes -7- at either end. of the drag to permit said drag to be drawn endwise upon the shoes in which case, theV lower edges of the scraper blades run clear of the ground as clearly shown in Fig. 4.

In order that the driver may ride upon the drag and to provide suitable means for supporting weights, I provide the drag with a foot or runner board or plank 11P- running lengthwise of the frame and secured at its ends substantially midway between the ends of the cross bars Q by suitable fastening means as bolts -12-. Y

The operation of this device will be clearly understood upon reference to the foregoing description taken in connection with the drawings, and it is evident that it has a wide range of uses not mentioned, particularly in filling ruts by reason of the ycur`ved form of blade which when drawn along the road bed at any'suitable angle throws the dirt from the sides inwardly and slowly toward the center where such accumulated dirt is distributed into and fills the ruts.

What I claim is:

l. In a drag of the class described, a frame composed of opposite lengthwise side bars and cross bars secured thereto and holding said side barsa xed distance apart, and scraper blades removably secured to said lengthwise bars, said scraperblades projecting vertically beyond the lower and upper sides of the frame. a

2. In a drag of the class described,'a frame composed of opposite lengthwise side .bars and cross bars secured thereto and holding said side bars a fixed distance apart, and scraper blades removably secured to said lengthwise bars, said scraper blades beingL removable and invertible upon the framewhereby either of their longitudinal edges may be brought n xt to the ground.

3. In a drag of the class described, a frame composed of opposite lengthwise side bars and cross bars secured thereto and holding said side bars a fixed distance apart, and scraper blades removably secured to said lengthwise bars, and runner shoes secured to the frame and normally projecting above the upper edges of the scraper blades whereby when the drag is inverted, it rests upon the runner shoes.

4. A drag comprising parallel concavoconvex side bars andtransverse cross bars rigidly secured to the side bars, and concavoconvex scraper blades secured to the side bars. 1 Y

5. A drag comprising parallel concavoconvex side bars and transverse cross bars rigidly secured to the side bars, and concavoconvex scraper blades secured to the side convex scraper blades secured to the sidel bars, a chain attached to one of the side bars near its ends, and a draft hook adjustable along the chain.

7. A drag comprising parallel concavoconvex side bars and transverse cross barsv rigidly secured to the side bars, and concavoconvex scraper blades secured to the side bars, and runner shoes secured to the normal upper side ofthe frame and projecting above the plane of the upper edges of said blades whereby the inversion of the drag brings the runners into contact with the vground to hold the blades clear thereof.

8. A drag comprising parallel opposite concavo-convex side bars spaced apart, cross bars connecting and rigidly secured to the side bars, concave-convex scraper blades secured to the side bars, runner braces rigidly secured to the junctions of the side and cross bars, runner shoes secured to said braces and to the cross bars, a foot plank secured to the cross bars, a draft chain secured to one of the side bars near its ends, and a draft hook adjustably connected to the chain intermediate its ends.

In Witness whereof I have hereunto set my hand this 6th day of May 1908.
