UNITED STATES PATENTOFFICE. 1
ROBERT H.'I-IAWKINS, OF CROCKER, ISSOURI? ROAD-MACHINE To all whom it may concern:
of Missouri, have invented certain new'and and useful liiiprovements in Road-Machines; and I do hereby declai'e'the following to be a full, clear and exact description of the inventiomsueh as \\'lll enable others skilled in the art to which it appertains to make and use the same. i v
This invention relates to road machines,- and the principal object is to provide amachine of this character for use in grading and recrowningr the surfaces of roads in a novel and efficient manner.
Another object of the invention is to provide a road machine embodying a pair of rotary scrapers for scraping the dirt froin the sides of the road toward the center,-s0 thatlthe rollers which follow immediately in rear of the scraper can roll the dirt down into the wagon and horse tracks as Well as any rats that may be present.
g'VVith these and other objects in view as will appear as the description proceeds, the
- invention comprises the various novel features of construction, combination and'ar-z rangement of parts as will be fully described hereinafter and afterward $10801 lically claimed.
In the drawin s Figure 1. represents a'plan View of the road machine. 1
Fig. 2 represents a side elevation thereof.
Fig. 3 represents a transverse sectional- View through a portionfof one of the rotary scrapers, and
Fig. 4; represents a fragmentary detail perspective view of the connection of the llltLlIl frame with the front running gear.
in order that the construction and. operation of thej-invention maybe readily 0010- prehended by those which the invention relates,
main. frame and 2 the rear and comparalively wide part," said latter .part' having connected thereto by suitable hanger straps i, a plurality of concrete rollers 4 and 5, each of which has its opposite ends bound with a reinforcing metallic band 6 .to pre- Specification of Letters Patent.

vent the edges from crumbling or breaking while in use.
1 An arch frame 7 is mounted transversely of the main frame immediately in'advance of the rear portion and .is connected to and braced to the wider portion 2 of the main frame by suitable braces 8, 9 are concrete ground-packing rollers having their 0 posite ends provided with metallic rein orcing bands 10, each of said rollers being fixed ends of the arch frame I A bevel gear 12 is fixed on each shaft 11 and meshes with a naled in a bearing 15 attached to theunder side of a platform 16 mounted on the part 1 of the main frame. l I
A rotaryscraper 17' is mountedon each I sideof the front. portion of the main frame and extends forwardly and outwardly at an angle thereto, as clearly shown in Fig. I. ,Said scrapers have their axes in a substantially horizontal plane, and the axis of said scrapers diverge forwardly or are oblique to the longitudinal axis ofthe machine. Each oflthese rotary scrapers comprises a shaft 18 on which is fixed a non-circular,
By reference to Fig. 3, it will be notedthat each so aper. arm is substantially semicircle l lar for the rumor portion of its length, wh le the remaining POI'tiOII thGIIGOf is pro-'f vided witha rebent hooked endQl adapted to normal] -,ei igage and scrape the surface of tie ground. With thefspring scraper arms constructed in this manner," they will, while'rotating, effectively scrape the surface of the road and throw the dirt in'toward the. center thereof without the liability o'f'the hooked ends 21 digging-into the ground. 'Ihesescraper arms are detaclion a shaft 11 joiirnaled in suitable bearings carried by the main frame and the opposite ably connected to the sides of the non-cirf cular hat by bolts 22, so that iii-the eventone of, them should become unfitffori se, it
can -be readily replaced by another one.
. The outer fend'of each shaft 18.is pro videdwith a supportingjwheel 23 while the inner end isic'on'nected to'the stub'shaft 14 by a'universal joint 24. 25 is a stay rod. connecting the outer end of each shaft 18 t0 the main frame." i I These rotary ;-scrapers just described are adapted to be raised and lowered. through 70 bevel gear 13 fixed on a stub shaft 14 jourthe medium of suitable lever mechanism lever 32, arranged adjacent the drivers seat- 83, is connected to each bell crank 31. The ratchet levers connected to each pair of levers 26 and 27 are arranged on opposite sides of the drivers seat, so that one may be grasped by the right hand and one by the left hand to raise the opposite ends of the desired rotary scraper. This raising and lowering of the rotary scraper will be permitted through the universal joint 24.
The front part of the main frame is connected to the bolster 34 of-the front running gear by a kingpin 35. 36 is a coupling member secured to the front end of the main frame and projecting through a slot 37' in the bolster 34 to receive the king pin 35. 38 is a suitable brace attached to the king pin between its head and the bolster 34 and to the main frame by being extended downwardly beneath the hounds 39.
By the use of a machine of this character, it will be noted that the rotary scrapers will scrape the dirt from the opposite sides of the lOiTCl in toward the center thereof, so that the rollers following immediately will roll thescrape'd dirt down into the horse and Wagon tracks as well as any ruts that may be present. \Vith the arrangement of the rollers as shown, it will be noted that the rollers '9 follow in the .wagon tracks or ruts, the rollers 5 in the horse tracks and the rollers 4 along the opposite sides of the road. By making the rollerscomparatively short and individually supporting thcinfronrthe main frame, provision is made for rollersto v adjust themselvcs'to the crown of the road.
From the foregoing description, taken in connection with the accompanying drawings, it is to be understood that while I have described the principle of operation of the invention, together with the device which I consider to be the best embodiment thereof, I desire to have it understood that such changes in construction. and arrangement of parts may be made when desired as are within the scope of the appended claims.
Having thus described my invention, what I claim as new is 1. A road machine comprising a plurality of rollers disposed in different transverse positions, a frame mounted on said rollers. rotary scrapers at opposite sides of the main frame in front of said rollers and having their axcs arranged obliquely relatively to the longitudinal axis of the frame, an operative connection between each scraper and a corresponding roller at the same side of the frame including a universal joint, and individual means for supporting each scraper for adjustment from the frame.
2. In a road machine, a transverse-ground packing roller, a frame mounted on said roller, a scraper carried for rotation and ad ustment by said frame and arranged with its axis horizontal and oblique to the longitudinal axis of said frame, said scraper beingloeated forwardly of said roller to ,operate on the ground in front of said roller,
- at ana'ngle thereto, each scraper enibo ying a shaft, resilient'spring scraper arms attached to said shaft. means for driving each shaft from the adjacent roller, universal means interposed between said'Ydriving means and scraper shaft, and means for raising and lowering said scraper shaft.
4. In a road machine of the character-described, the combination with a rotary scraper shaft, of a plurality of resilient spring scraper arms, each arm composed of a piece of fiat s ring steel substantially semicrrcularfor t e greater part of its length and rebent to form a hook for the remainder of its length for engagement with the sur face of the ground.
5. In a oad machine, a set of transverse rollers to roll on'and pack tlie'ground, a frame mounted on said rollers, rotary scrapers in front of said rollers and having their axes in a substantial horizontal plane and diverging forwardly obliquely relatively to the longitudinal axis of $21K frame,
said scrapers having ground-engaging arms,
to operate on the ground in front of said rollers. means for supporting said scrapers for vertical adjustment fronr the frame, means for driving said scrapers from said rollers having universal joints with the rear one" of the scrapers, and means for supporting the forward ends of the scrapers from the ground. Y
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
