l ROAD MACHINE.

Application filed April 7, 1927. Serial No. 181,742.v y

laterally, so that its bottom will assume a proper angular' position, corresponding to the desired crown of the road. chine is so constructed that` the road may be laid in a desired number of layers, of suitable thickness. When each layer is laid, it is suitably packed by a traction device, which also serves to propel the machine, and the deposited layer will be smooth and solid.

The distributing box and supporting so that an oil spraying mechanismy may be placed upon the machine, in the place occupied by the box.

The machine also preferably embodies ak scarifying mechanism, arranged in advance of the distributing box, and serving to cut up and level the road, to the desired eleva tion, prior to the placing of the layer of concrete or the like upon the same. j

The various parts of the machine areal] under control of the operator and the machine as a whole is convenient to manipulate.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the drawings, wherein for the purposey of illustration, is'shown a preferred embodiment of my invention,the numeral 10 designates a frame or chassis, embodying longitudinalbeams 11, preferably in the form of channel irons.

The forward end of the chassis is supported by the front wheels 12, having the usual steering mechanism 13, associated therewith, which is operated by a steeringy wheel 14;, arranged within a cab 15. Mounted upon the chassis inl advance of the cab 15 is an engine 16 of any well known or preferred type, driving through transmission gearing 17, of any well knownor preferred type. f

The rear end of the frame or chassis l0 is provided with depending brackets 18, rigidly attached thereto. These brackets are provided in their lower ends with journals for receiving a transverse axle 19, held therein against longitudinal displacement. In-

dependently rotatable upon this axle or shaft are large toothed wheels 20, having tubular hubs 21. the outer portions of the tubular hubs 21 are rocker arms 22, extending beyond the shaft 0r axle 19, forwardly and rearwardly, for substantially equal distances. These rocker arms are provided at their free ends with bearings 23, for receiving transverse shafts 24, upon which are independently rotatably mounted smaller toothed wheels 25, there being two pairs of these toothed wheels 25. Passing about the sets of j toothed wheels and 25 is a pair of'longitudinal sprocket-chains 26, provided upon their outer sides with continuous endless 4treads 27, which may be formed of flexible sheet Pivotally mounted upon f metal or other suitable material, and secured i lli) the tubular hubs 2l are spi'ocket wheels 28, engaged by sprocket-chains E29, extending forwardly, and engaging sprocket wheels 30, which are rigidly mounted upon separate jack shafts 31. These jack shafts lead to gearing 32, driven from the transmission gearing 17. The gearing 32 is preferably of such a construction that the jack shafts may be rotated at dill'erent speeds, and if desired one jack shaft may be driven in an opposite direction to the other jack shaft, whereby the endless treads may be driven at Vdifferent speeds, and in opposite directions, if desired. 'lhe gearing 32 may be in the 'form ot the ordinary dili'erential gearing, it desired.

Arranged near and at the rear of the front wheels 12 is a scarifying mechanism, enibodying a transverse shaft 33, upon which are rigidly mounted sharp disks 34. The ends of the shaft 33 are journaled within openings 34', formed in carriages These carriages are equipped at their sides with guide rollers 36, t0 engage the walls 37, formed by openings in depending brackets 3S, which are rigidly attached to the side beams 11 and depend therefrom. The carriages 35 are equipped with outwardly projecting lugs 89, having swiveled connections with vertically adjusting screws 4t), having screw-threaded engagement within bearings 41 and 42, rigidly secured to the brackets 38. The upper ends of these adjusting screws are provided with heads 43, so that they may be turned by means of a wrench or the like. lt is thus seen that the scarifying cylinder may have both ends adjusted vertically, for the same distance, or the opposite ends of the scaritying cylinder may be raised for dillerent distances, whereby the scariiying cylinder may assume a selected transverse angle. There is sul'ticient play between the lower ends of the adjusting screws 40 and the lugs 39 to permit ot this angular adj ustment.4

Arranged within the traine oi' chassis 10, directly behind the scariiying mechanism, is the distributing mechanism, embodying a distributing box 44. This distributing box is generally vertically arranged, and extends transversely of the frame, as its bottom is entirely open, and is preferably provided at its top with a flaring mouth or hopper 45.

Arranged forwardly of and near the distributing box 44 is a suitably still' transverse sheet or plate 46, the upper end of which extends bet-Ween the longitudinal beams 11, and is bolted or otherwise rigidly attached to a transverse beam 47, secured to the longitudinal beams l1. The plate 46 is extended laterally beneath the beams 11 and extends outwardly so that its ends are substantially flush with the outer surface of these beams. The late 46 has rigid connection with bracebrac ets 48, which are rigidly attached to the plate and to the lower sides of the beams 1l. In a similar manner, a transverse sheet or plate 49, which is suitably still', has its upper end reduced and extended between the beams 11, and this upper end is rigidly attached t0 a transverse beam lit), secured to the longitudinal beams ll. Beneath the beams ll, the vertical edgesl ol the plate 4l) project outwardly and are substantially llush with the outer surface of these beams, and the plate 4t) is rigidly attached to bracebrackets 51', which are also attached to the lower surface of the beams.

Preferably detachably rigidly secured to the front transverse plate 46 and the rear transver.-e plate 4t), are pairs ol vertical uprights 5l and 52, provided at their upper and lower ends with horizontal extensions all and 54. rlhe upper extensions and h4 have openings tor rotatably receiving smooth portions oi adjusting screws provided at their upper ends with socketdieads 56, whereby they may be turned by a suitable tool. The lower smooth ends of these screws .operate within recesses, formed in the tops of the lower extensions .3b and 54. Mounted upon the screw-threaded portions of the vertical adjusting screws 55 and having screw-threaded engagement therewith are blocks or carriages 5S, provided with headed studs 59, Jivoted within sockets 6U, which ai'e rigidly attached to the front and rear sides ol the distributing box. These sockets 6() have horizontally elongated openings or slots 55)', upon their outer walls to receive the shanlis of lhe studs :35). It is thus seen that the distributing box is adjustably supported near its four cornersl and that it may be shifted to the selected elevation willi its open bottoni horizontally ariaiigcd or it may be shifted to the selected position with its open bottom tilted laterally, for producing the proper crown for the road.

Rigidly and detachably secured to the lower ends oi the rear uprighls F2 are brackets 6l, carrying a roller 62. as shown. ln Figures 6 and T, is'shown a inodil'ied forni of scarilier, embodying a transverse frame 63, provided at its ends with arms 64, having heads 65. These heads have swiveled connections with the lower ends ofthe screws 40. Rigidly held within the frame 63, by bolts 66 or the like, are horizontal blades 6'?, the rear edges ot' which are stepped as shown.

The operation of the machine is as tollows:

The machine is driven forwardly along the road, at a slow speed, such as a mile and a half an hour. The scarifying mecha nism embodying the blades 34 engage the roadbed and cut or dig it up and level it oil'. The distributing box then passes over the roadbed thus treated and the material to bc applied to the roadbed, such as concrete or Sll lll)
