NATHANIEL S. MONROE, OF ARTHUR, ILLINOIS.

ROAD-WORKING MACHINE.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed March 12, 1914. Serial No. 824,161.

To all whom it may concern Be it known that I, NATHANIEL S. Monnon, a citizen of the United States, residing at Arthur, in the county of Douglas and State of Illinois, have invented certain new and useful Improvements in RoadJ/Vorking Machines, of which the following is a specification.

This invention relates to road leveling machines or devices of a type for which several patents have been granted to me, as, for instance, Patent No. 1,015,820, dated January 30, 1912, and which in their construction embody forwardly diverging and rearwardly converging scraper bars carried and supported by a wheeled frame and suitable adjusting means.

he present invention has for its object to provide simple, novel and efficient means whereby the material issuing between the rearward ends of the scraper bars will be smoothed and compacted in a thoroughly satisfactory manner. a

A further object of the invention is to provide smoothing and compacting means carried directly by or upon the scraper bars at the rear ends thereof so as to operate directly on the surfacing material issuing between the scraper bars.

A further object of the invention is to provide means of the character described connected with and carried by the scraper bars which will not interfere with the individual and independent adjustment, longitudinally, of said scraper bars.

A further object of the invention is to provide means of the character described which may be adjusted to exert a required degree of pressure on the surfacing material issuing between the scraper bars, the pressure being supplied, if desired, by the weight of the scraper bars.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,Figure 1 is a top plan view showing the rear ends of a pair of scraper bars and the smoothing and packing devices applied thereto in a simple and preferred form. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation showing a different adjustment of the smoothing and packing device. Fig. i is a top plan view, partly in section, illustrating a modified form of the invention. Fig. 5 is a side elevation of the same. Fig. 6 is a side elevation showing a different adjustment of the parts. Fig. 7 is a perspective detail of a portion of the device.

Corresponding parts in the several figures are denoted by like characters of reference.

In the form of the invention illustrated in Figs. 1, 2 and 3, the smoothing and packing member, here designated by 15, is shown as consisting of an angle bar, L-shaped in cross section, but it is desired to be understood that no limitation is made as regards the particular shape of said member. Said packing member is connected by hinges 16 with a supporting bar 17, also shown as consisting of an L-shaped angle bar, said supporting bar being connected by pivots 18 with the rear ends of the scraper bars 19 which have been shown as being equipped with lugs 20 at the rear ends thereof for the passage of the pivots. The supporting bar 17, it will be seen, also constitutes a spacing member whereby the scraper bars 19 are connected together and spaced apart at their rear ends without interfering with the independent longitudinal movement of said scraper bars and without interfering with the dirt issuing between said bars. The angle bar constituting the smoothing and packing member 15 carries an upwardly extending arm or lever 21 having notches 22 adapted to be engaged by a dog or pawl 23 which is connected with the bar or supporting member 17. The arm or lever 21 has a handle 24 whereby it may be manipulated to place it at various angles with respect to the supporting bar 18, the dog or pawl 23 being used to retain it and related parts in adjusted position. It will be readily seen that by depressing the lever 21 the rearward free edge of the smoothing and packing member will likewise be depressed, thereby causing it to exert a relatively heavy pressure upon the material rissuingabe'twe'en Qthe irearwand ends of the scraper bars 19. The adjustment may, if necessary, be suflicient to elevate the rearward ends of the scraper bars, 5 as clearly indicated in Fig. 3, causing the weight of said scraper bars to be exerted on the material issuing between their rearward "ends through the mediumof the smoothing and packing member 15. As thesexscraper bars are usually of large dimensions and of jheavy weight, *it'will be readily seen that this device may :be utilized extremelyeffec- I tivelytosmobth and pack the *road material and-to leave-the road in a*finely-finished l 5 1- condition.

'T'he purposes of 1. this invention m'ay be attained'in various ways besides thatwhich has -just been shown i described,- and for Rpurposes of illustration I reafer tM Figs; 4

% 2O-to .7, inclusive, by=referenceito which it will be seenthat the smoothing and pa'cking memberg h'ere designated by is connected by flexible connections, such as links 25, with the rearwardends of the scraper bars 19. Adjusting 'levers 26 are fulcrumedon the side faces of the-scraper'bars neari 'the 1-rear=1ends of the =latter,:lsaidllrlevers having wrearwardly extending '-.'arms- 27 engaging .vkeepers 28" on= the I smoothingi and epacking 30*-:mem=ber '15. 'l he levers may be secured at various? adjustments by Y means iof fastening amembers, 'such-as bolts 29 for the'xpas'sa-ge' of *which each scraper bar: is provided wi'thi a series=ofi apertures i 30.
