ROAD-WORKING MACHINE.

- Specification of Letters Patent.

Patented April .28, 1908.

Application filed llay 3, 1907. Serial No. 371,704.1.

To all whom it may concern:

Be it known that I, WILLIAM B. BROTH- Ens, a citizen of the United States, residing at lllio olis, in the county of Sangamon and State of Illinois, have invented new and useful Improvements in Road-Working Machines, of which the following is a specificatlon.

This invention relates to a road working machine and more particularly to a scraper for grading new or old roads.

The invention has for one of its objects to improvel and simplify the construction and operation of an apparatus of this character so as to be comparatively easy and inexpensive to manufacture and thoroughly reliable and efficient in use.

Afurther object of the invention is the provision of a road scraper in which the blade or blades can be readily adjusted torthrow the sand, mud or other material of the road to thel right or left, there being means for changing the set of the blade or blades.

Another object is the employment of a pair of parallel blades connected with a platforn'i extending between them, which together with the blades, can be adjusted to anydcsired angle to the line of travel for permit ting the material to be thrownrtoward the center of the road from the right or left, the blades being provided with devices for independently adjusting them.

Nith these objects in view and others as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which will be more Jfully described hereinafter' and set forth with particularity in the claims appended hereto.

in the accompanying drawing which illustrates one of the embodiments ofthe invention,. the iigure isa perspective view of the improved road working machine.

Referring to the drawing, 1 designates a Hat 1 latform extending the full width of the machine and secured thereto is a central beam 2. Extending arallel with the platform and under the lgeam 2 are Scrapers 3 which may be in the form of beams of iron or wood like the parts' 1 and 2 and provided with removable olades 4 extending the full width of the machine. The ends of the Scrapers 3 are connected by links 5 with the ends of the, platform 1, there bei provided clips or similar fasteners 6 bolte or otherwise secured to the platform 1 and thus bracing the Scrapers on the platform. The Scrapers are suspended adjacent their centers on inde endent levers 8 fulcrumed, at 9, respective y on the front and rear end of the center beam 2, there being toothed sectors 10 on the beam and latches 11 cooperating therewith, whereby the sera-pers can be set at any desired angle in respect to the vertical plane. The pivots 9 are horizontal so that by actuating the levers S, the( blades can be inclined forward or rearward as desired. On the platform 1 is arranged a driver-s seat 12 from which the levers 8 are within convenient reach of the driver so that he can adjust the Scrapers with facility.

The apparatus is provided with a tongue 13 disposed directly in lin `with the central beam 2 and hingedly conirbted at 14 with the center of the front scraper and attached to the tongue or pole '13 is a double-tree 15 wherebythe machine can be drawn by horses Extending from the doubletree is a brace.

rod 16 that is bowed and has its ends 17 hingedly connected with the terminal portions of the front scraper 3. The middle portion ofthe brace rod is provided with'a series of apertures 18 arranged in the arc of acircle and in any one of these apertures is engaged a p in 19 that extends vertically through the tongue 13, there beine' a late 20 under the tongue for receiving t e` ottoni end of the pin and between which and the under surface of the tongue the flattened apertured ortion 21 of the brace rod is slidably he d. As shown in the present instance, the pin passes through the central aperture so that the Scrapers are held at right angle to the direction of travel of the machine. the pin and svi/inging the tongue in any of the other apertures, the Scrapers will assume a position inclined to the direction of travel of the machine so that the surface material of the road can be thrown to the right or left, as

' desired.

From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and of the method of o era-tion will be readily apparent to those s rilled in the art to which the invention appertains, and while I have described' the principles of operation of the in- By removing vention/together with theapparatus which I i now consider 'to be the best embodiment thereof, I desire to' have it understood that ,the center of the the a paratus shown is merely illustrative and tlat various chan es may be made when desired as are Within t e scope of the claims.

Having thus described the invention, what -I claim as new is:

` tween the ends of the elements and platform arranged to permit the elements totilt, a tongue ieiribly connected ywith* the front ele ment, a bowed bar connected with the ends of the 'front eler'nent and extendinr forwardly therefrom, and means for connecting' the tongue with the bar.

2. ln a roed working machine, the combination of. a traine, parallel surface Working elements, levers fulcrumed on the frame to swing in e Vertical plane on horizontal pivots and rigidly connected with the elements et the front thereof for tilting the same, and

c means for bracing; the ends oi the elements on the frame, a draft member flexibly con-- nected with the front element, a bowed rod a l l esame connected With the front element and eX- tending forwardly therefrom and connected with the tongue.

3. In a road Working machine, the combination of a latform, a cross beam at the middle thereo surface working elements erranged in Jfront and behind the platform, ad-

justing levers mounted on the bearn'and connected with the elements for tilting the same, `links between the ends oi' theplatforrn and elements, and to which the links are connected, a draft device connected entirelyT with the front elenient.

Li., In e road Workin@ machine7 the combination of a trame, surlaace working elements thereon, means for tilting the elements independently and holdinv them in adjusted position, a tendue lexib y connected at its rear end to the ijront element, and connecting l means between the tongue and the extremities of the front element.

In testimony whereof, l aflixniy signature in presence of two witnesses.
