For afull' understanding of the invention.

and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a top plan view of my improved road machine. Fig. 2 is a side elevation thereof. Fi 3 is a longitudinal sectional view on the line of Fig. 1. transverse sectional view on the line 44 of Fig. 1. Fig. 5 is a detail side elevation, partly broken away, of a portion ofthe extensible front beam of the frame work.

Fig. 6 is a detail transverse sectionon the line 6-6 of Fig. 5. .Fig. 7 is anenlarged detail sectional view hereinafter specifically referred to. Fig; 8 is a top plan view of the Fig. 9 1s a detail view Figs. 10 and 11 are the worm gear,

of one end of a bolster.. detail top and front views of and Fig. 12 is a detail view of one of the wagon or vehicle and the operating frame-' work and actuating parts carried'by the said vehicle.

The vehicle includes travellng wheels 1,

' rear and front axles 2 and 3, and reaches 4 of which there are two shown, spaced from each other and which are connected at their rear ends to the rear axle 2 and at their front ends to the bolster 5. Said bolster is provided with upwardly and outwardly projecting elevated ends 6, which extend over. the front wheels and give sufficient clearance to smoothing or otherwise working h pinion 10, the latter meshing with a toothed I shall hereinafter Fig. 4isa the latter in turning. A platform 7 is supported by the pair of reaches 4, reaches extending therethrough, as indicated by dotted lines in Figs. 1 and 3, and the 0 erator or driver stands on this platform an I manipulates the different actuating elements ofthe apparatus. projects upwardl which is provider and wheel 9 and from the platform and at its lower end with a steering segment 11 secured to the front axle 3 at opposite sides of the fifth wheel. 12 desi nates a detent wheel which is fast on the ower end of the rod 8 and which-is designed-to be engaged by a foot operated detent 13.

The frame work which is supported by the vehicle. above described, and which is adapted.v to be elevated or suspended therefrom when not, operating, and be let down into en agement with the road when operat ing,'inc udes a front cross formed in three sections. To the intermediate or main section 15, the draft tongue 16 tensible sections that are slidingly connected to the main section by means ofcoupling sleeves 18. Each of the extensible side sections 17 of the front cross-beam is provided with a rack 19, and pinions 20 are journaled in the main section and. mesh with said racks. Ratchets 1 are secured on the shafts of the respective inions 20 and are adapted to be engaged by double pawls 22 carried by levers 23 Hence it will "be seen that by manipulating either of the two hand levers 23 or both of them, either one or both of the sections 17 may be extended .laterally or retracted. The frame work also includes longitudinal beams 24 which are secured, preferably by inwardly extending angular ortions to the ends of the extensible sections '17 of the front cross beam. 1 These longitudinal beams 24 converge towards their rear ends as shown and are connected by hinges 25 to the rear crossbeam 26. Both beams 24 and the rear .cross beam 26 are provided with inwardly extendin cuttin or scraping edges 27 as clearly il ustrate in the drawings. The longitudinal 24ecrry near their front ends, and l abl at the angle of their main portions with gtheir inwardly extending firont portions, 110

is secured. 17 designates the two side or exfulcrumed on said shaft.-

These shafts- 60 manipulating the hand -lever--it-ismanifest that the movable arm 50 may be raised or lowered so as todisengage the worm from scraping blades 28 that are secured thereto in'its operation. nected to themain sections 15'of the front] cross beam, and converge towards theirrcar by standards 29 and that are preferably provided with returned front edges 30extending around the front edge of th e"scrap" ing or cutting portions 27 of said longitudinal Theseslidingbeams, as best seen in Fig-12 v I scrapers are sharp and are provided for "the purpose of cutting against road hanks and-for the further purpose of steadying the machine Coupling irons 3ia1f e conends, such ends beingconnectedtogether,preferably as an integral structure, and being 5- mounted to slide vertically in a slotted guide frame 32 preferably supported on the bolster and having its ends connected to the upper and lower ends of the kingbolt. Chains 33 are connected at their lower ends in ,anys'uitable way to the respective longitudinal beams 24 near the front ends of the latter and the said chains extend upwardly through slots 34 in laterally movable slides 35. The upper ends of the respective chains are adapted to wind over grooved sheaves 36 fast on the are ournaled in bearings 38'on the slides 35,

and the said bearings [maybe formed by turning. the ends pf-sa-i'd slides upwardlya as shown, or in any desired manner. "The I hand wheels 39.

The worm' gears 45 are preferably held relatively stawaste tionary as the shafts 37 are carried inand out on the slides, and the means for holding said Worm gears stationary comprises in the ,present'inst'ance a pair of rollers carried on a fork 45? secured to the stationary arm'49 of the bracket 48.

The lrea chesf4 are provided at their rear ends with arches56. I A chain ,57" is secured atiits lower-end to the rear cross beam '26, and the upper end of the chain is adapted to.

wind around a grooved sheave 51 on the longitudinally extendingv shaft 58. This shaft isprovided at its front endwitha hand a wheelin'eonvenient reach'of the operator, so

that it may be rotated, and it is journaled in bearings supported upon cross bars secured at their ends to the arched portions of the reaches. 61 desi ratchet adapted to hold t e said shaft at the requisite adjustment. A slotted guide 62 projects upwardly from the rear axle 2 and a guide arm 63 projects upwardly and rear wardly from the rear cross beam 26' and projects into the slot of'th e'guide 62-so as to properly maintain the rear cross beam when it is being raised or lowered 64 designates-a pair of braces that are pivotally connectedat their front ends to the extensible, sections 17 of'the front cross beam 14, andt'hat are provided with hooks 65 at ates a pawl and i their. rear endS adapted to 'beentered into anyone of a serles of apertures 66 formed in the horizontally extending portionsof the longitudinal beams 24.- When the machine is being carried'from place to'place and is not in actual operation, it is evident that the entire framework may be sus ended in an elevated position from the ve practical operation, the frame work is lowered to the desired elevation so as toscrape and properly grade or otherwise ,work the road, as 1t is drawn forwardly along'the road by either a traction engine or.- other prime mover, .or a team of horses hitched to the tongue 16. -By mani ulatin the hand le-' vers 23 the framewor contracted laterally, the required distance,

In the I may. e extended or the braces 64 being'released-from the longitudinal beams of the frame work during t e operation of adjustment, and then engaging again in one of they openings in the said pitman. From the foregoing descri tion in connection with the accompanying rawings, it is evident that the slides will adjust themselves laterally, or they may be adjusted by hand, when the frame work is extended or contracted, and that either side or'bo'th sides of the framework maybe held at the proper operating depth or elevation along the road by actuating the worrpsiand worm gears, or

by'o'therwiserotating the shafts 37; Itv is also obvious thatthe rear end of the framework may be raised; oi lowered whenever desired- For' instance, it may be lowered for engagement with the groundso as to cut off arcane knobs or ridges, and drag dirt into low places for leveling the road, orthe said rear end may be elevated forthe purpose of allowing soil to escape from underneath the machine. As the machine is made in two parts, namely'the vehicle and the frame work, the former with its weight on the ground will hold the entire machine steady, and this result will also :be accomplished partly by the sliding scraping blades 28.
