S. FRANK WVELOH, OF MOUNT PLEASANT, IOWA, ASSIGNOR TO THE TEST- ERN WVHEEL SCRAPER COMPANY, OF SAME PLACE.

ROAD-WORKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 323,002, dated July 28, 1885.

Application filed MitlK'll .7, i885. (N'o model.)

To all whom it may concern.-

Be it known that I, S. FRANK WELoH, of Mount Pleasant, in the county of Henry and State of Iowa, have invented certain new and useful Improvements in Road-W'orking Machines; and I do hereby declare the'following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in road-working machines, the object of the same being to provide improved means for conveying earth from the sides of the road to the center, leveling rough places, cleaning out old ditches, or filling ditches,'and other work of a like character; and with thcse ends in view my invention cousists in a scraper-blade pivotally secured to a supporting-frame in 2Q horizontal angular adjustment, the support ing-frame being secured to crank-axles in tilting adjustment.

My invention further consists in a scraperblade mounted upon wheels and provided with a colter-guide to prevent slu'ing, loosening the earth, 8m.

My invention further consists in certain features of construction and combinations of parts, as will be hereinafter described, and

pointed out in the claims.

In the accompanying drawings, Figure 1 is a view of the machine in perspective. Fig. 2 is a view in side elevation, one of the wheels being removed. Fig. 3 is a plan View, the

3 5 drivers seat being removed. Fig. 4 is an enlarged view of the scraper, showing the colter attachment; and Fig. 5 is an enlarged View of a portion of the scraper-blade and circle, showing the manner of attaching the blade.

A is the main axle, or more properly a bar connecting two stubaxles, a. The tongue T is secured to the bar A, and extends rearwardly therefrom for the attachment of the scraper-blade, as will appear further on. The stub-axles a are cranked, their inner ends being jo'urnaled to the bar A in suitable bearings I), and their outer ends carrying the supporting-wheels W. Operating-levers L are secured to the inner ends of the crank-axles a, and are provided with springactuated dogs d,which engage toothed sector-bars R,se-

cured on the bar A or on the bearings b, attached to the bars A. A spring-standard, X, carrying the drivers seat S, is secured to the bar A between the operating-levers L in such a position that the handles are within convenient reach of the driver when seated. Two hounds, h, are secured to the under side of the bar A, one on each side of the tongue, and diverge from each other as they extend rearwardly. A circle or are of a circle, 0, preferably the latter, is attached to the tongue and to the ends of the hounds h, thereby bracing the tongue and at the same time securing the circle or are rigidly in position.

B is the scraper-blade, and it consists preferably of a curved metal sheet of suitable thickness provided with a steel edge. The blade is re-enforced by a number of ribs, K, bolted to its rear face. One of the ribs K is located at the center of the blade, and is provided with rearwardly extending perforated lugs 1', through which one branch of a U-shaped bolt, D, passes. The ends of the bolt D are secured to the rear portion of the tongue T, and thus secure the scraper-blade thereto in a horizontally swinging adjustment. Two of the ribs K are located a distance apart equal to the diameter of the circle or are 0, and terminate at their upper ends in fiat heads 1], 8c which extend beyond the edges of the circle, and are provided with bolt-holes just outside of the edges of said circle. A short bar, M, provided with corresponding perforations, is located on the upper side of the circle, and the heads E and bars M are drawn in snug contact with the circle by threaded bolts m, provided with draw-nuts m.

By means of the fastenings the scraperblade is locked in any desired horizontal anguc lar adjustment.

Other forms of fastening than that shown might be conveniently employeda clip, for

example, or yoke and thumb-nuts; hence I do.

not wish to restrict myself to the particular form shown.

A V-shaped frame, f, is secured to the rear faces of the two end ribs, K, in the ends of which frame an axle-rod, n, is secured. A rolling colter, H, is secured on a sleeve, is, which latter is mounted on the axle-rod n. The colter is 10- cated 011 the outer end of the sleeve k, and

rod or, to cause the colter to cut deeper or.

shallower and change its angular adjustment with reference to the scraper-blade when the angle of the latter is changed relatively to the line of draft. The framef is braced by a diagonal rod, 9. 1

The colter and colter supporting frame above described are located in the rear of the scraper-blade; but in many instances it may be found desirable to locate them in advance of the cutting end of thescraper for the purpose of cutting and loosening the earth, to give the scraper'blade a better hold and to lessen the draft by loosening the earth, and at the same time prevent the sluing of the blade as before. A hanger-strap, J, is bolted to the under side of the tongue for the purpose of lowering the draft sufficiently to take all neckdraft of the tongue T, and a foot-rest, P, is at tached in convenient position to the tongue.

By means of the operating-levers L the crankaxles a are rotated, and the scraper blade thereby tilted to the right or left, elevated or depressed, as may be desired, and by means of the circle or are C, the pivotal support D, and the devices for locking the blade to the circle the blade may be swung to work right or left handed, set at any angle desired to the line of draft or at right angles thereto, while the colter H prevents the sluing of the blade and cuts a guide line for the second passage of the scraper in cases where it is used to excavate, and adds very little to the drag.

It is evident that slight changes may be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the construction herein set forth; but,

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. -In a road-working machine, a scraper blade pivotally secured to a supporting-frame in horizontal angular adjustment, and adapted to be vertically adjusted by means of rocking axles, substantially as set forth.

2. The combination, with a scraper-blade secured to a supporting-frame in horizontal angular adjustment, of a pairof crank-axles secured to the supporting-wheels, and means for rocking the axles and thereby tilting and vertically adjusting the scraper-blade, substantially as set forth.

3. The combination, with a bar having axles j ournaled to each end and supporting-wheels mounted on the axles, of the tongue secured to the said bar, the scraper-blade pivotally secured to the tongue, the circle or are secured to the tongue and bar, and means for locking the scraper-blade to the circle or are in horizontal angular adjustment, substantially as set forth.

4. In a road-working machine, the combination, with a supporting-frame, of a scraperblade pivotally secured to the supportingframe by a U-shaped bolt, one of the legs of said bolt acting as a brace to support the lower end of the other leg, substantially as set forth.

5. The combination, with a vertically-adjustable supporting-frame and a scraperbladc secured thereto in horizontal angular adjustment, of a colter journaled in bearings secured to the scraper, substantially as set forth.

6. The combination, with a scraper secured to a supporting-frame in horizontal angular adjustment, of a rolling colter secured to the scraper-blade in horizontal angular adjustment, substantially as set forth.

In testimony whereof'I have signed this specification in the presence of two subscribing witnesses.
