of Michigan anddAMns l). BnNnow; a citi- Zen of the nited States, and a resident of Aurora; in the county of Kane and State of Illinoisj have invented certain new and useful Improvements in Gracling-l/lachines; of which the following is a specification; reference being had to the accompanying drawings.

Qur invention relates to road or grading machines of the type comprising a wheeled iframe and a scraper mounted under` the frame and arranged to be swung laterally and also to be adjusted angularly to the line of draft. lt has for, its primaiy object to provide a road machine with dirigible rear wheels mounted so that they may be shifted laterally with reference to the inachine frame for the purposeoit` holding the scraper to its work when set in an angular position, and also 'for aiding in guiding the machine and varying the operating position of the scraper. Another object is to provide such a machine with means independent ot the machine trame for steering such dirigible wheels` Vte accomplish these objects as illustrated in the accompanying drawings and as hereinafter described. lNhat we regard as new is set forth in the claims.

ln the accompanying drawings;- N

VFigure 1 is a side elevation of the principal parts of a scraper embodying ourA invention, the wheels at the near side of the machine being omitted;

Fig. 2 is an enlarged detail, being v`a paitial horizontal section on line 2v2 of Fig. 5; Fig. 3 is a partial plan view of the rear portion of the machine traine showingl the rear axle and the parts associated therewith; y y

Fig. l is a rear elevation oit the parts shown in Fig. 3;

Fig. 5 is an enlarged detail; being a partial vertical cross-section on line 5-5 of Fig. 4; y i y Fig. 6 is an enlarged detail, being a partial vertical sectionionlineG-G of Fio..` 5;

-liig. 7 is a partial plan view showing a .different torni 'of locking device for locking the steering mechanism;`

Fig. is. a rear `elevation of the parts shown in Fig. '7;and f u Fig. 9 is a partial longitudinal section on line 9- 9 ofliig. 8. i

ln the embodiment of our invention illustrated in the drawings,l7 indicates the ma! chine frame which is supported upon front wheels 8 and rear wheels 9. 10 indicates the usual scraper supporting frame which carries a scraper blade 11. These partsy may be constructed and arranged in any approved way which will providefor angular adjustment ol the scraper blade and also for its being swung laterally; and raised and lowered. The` usual practice is to pivotally connect the forward end of the scraper supporting 'frame 10 to the machine frame so that it may be raised or lowered. or swung laterally, and to connect the scraperblade 11 with the scraper support` ing frame 10 by means of a turntable 12 which may be rotated to vary the angular position of the blade. Suitable devices are mounted on the machine Viframe T for effecting the several adjustments, and in the illustration we have shown a shaft 13 `provided with a hand wheel 1li for rotating the turntable 12,'and a transversely mounted rack `bar 15 and pinion 16 operated by a shaft' Patented N ov. 2; 1921); f

vention is concerned it is not essential that the devices shown for accomplishing the several adjustments or' the scraper blade be used, as any other suitable means for the purpose may be employed. y

23 indicates a platiormprovided at the rear end portion or the machine frame, as shown in Figs. 1 and 3. 211 indicates the; rear aXle of the machine, which-is preferlos ably composed of oppositely arranged chan` nel beams 25-26 connectedby top and bottom plates 27-2S, as shown in Fig. 5, and is provided at its ends With yolres or i'orirsV 29 adapted to receive vertically disposed pivots 56. Mountedupon these pivots; are

sleeves 3i which are connected with the aide at one side thereof, as shown in Fig. 2, and meshing with a pinion '85 mounted upon a vertically'arraiiged shaft having Y a hand Wheel 37 by Whichit may be rotated, Y

as shovininv Figs.V l and 2. The shait is suitably mounted upon the macliinetraine, preferably by .means of a bracket 38 shown in Figs-l and 2, and itj'Will-beapparent that by 'rotating the shaft 86the rack bar Stand with it the axle 2a Will be moved endivise or transverselyof the machine. is shown in Figa, the rear axle 24 is connected with the machine Vframe by clips or stirriips 39 Which hcldfitfup against the under side ot the niachine iframe 7, and preferably rollers i0 are provided between the machine :trame and the i'ipperside oi' the rear axle to reduce friction, as shown in Figs. 4; and 5. il indicates va longitudinally disposed roch-shaft Which is journaled ina suitable housing i2 mounted on the rear axle 24;, as shown in Figs. e and 6, beingpreferably connected With said axleby a bracket a3, shown in Fig. `5. Said rock-shaft is provided with an arm @A which is connected by a steering rod 45 with cross-connecting rod i6 which connects the tivo arms 33 at opposite sides oi2 the machineso that the tivorear Wheels are Vsteered in unison. vYFreierably the stef-rball and socli'et connections yat its ends, as shown in Fig. fi, but any other suitable connections may be employed. .lt Willbe apparent that by roclr- Y ing the rock-shaft il the arm le/i may be sivung laterally, thereby steering the rear Wheels through the rod 45. Li7"indicates a segmental rack rigidly connected with the armi so as to swing therewith and with tlie'rocl-'shatt Lil. Said racli; is engaged by a latch lever i8 vpivotally'mounted on aisiipporting bracket 49 rising from the housing 42, as shown in Figs. 5.and 6, and normally held infengaeeineiit with said rack` by'a spring 56, as shown in Fig. 5. `This latch serves to hold the rack i7 in the 'different Y positions to which it maybe adjusted', but by depressing the :forward end orp said latch lever theraclr i7 may be released, thereby permit' tingthe rock-shaft@ to be rocked. :By this construction the rear Wheels maybe set in `different positions'of angular adjustment so that` they will operate to hold the scraper litro ecting rearwardly Worin vi'heel 5l mounted iii the housing i2 and meshing with a Worm 52 carried by a :vertically disposed shaft 53 also journaled iii Vthe housing i2 as shown in F ig. 6. This shaft carries a hand Wheel 54, slioivnin Fig.. 'f-i ehm' --i i T .i 1d;

i, .iy unitn Lt may oe rotated. it siiou ae Vnoted that the devices tor steering the rear Y wheels and for locking such Wheels in position are all carried by the rear aXlev so that` vvhen said axle is adjiisted'endivise .they moveivith it, and the angular position of the rear Wheels is consequently not disturbed by the movement endivise of the rear axle.

rihese are important `features of our inven-` tion and are claimed broadly.

F or normally locking the rear axleagainst enclwise movement a locking bolt 55 is provided, ivhich is mounted to move vertically in the rear portion of the main trame and engages one of a number of holes provided in the upper plate V27 of the rear axle. as shown in F igf5. spring 56 serves to exert doivnivardy pressure on the bolt 55, and a foot lever 5,77' provides means for readily lifting thebolt 55 out otengageineiit with` thel rear axle when it is` desired to shift said axle eiidvvise. 'in Figs. 7, 8, and 9 is another form of locking device for locking the Wheels inthe different positionsftoWhicl'i L v l l f they may be august-ed. ln the construction shown in said figures .the cross-connecting rod-i6 carriesv a flocking plateV 58 provided with, VV'series ofA perforations, which plate extends between upper and lower plate59--60 secured to the underside oit the bracket l-B and arranged to iform a slotted frame, as best shoivnin Fig. 9.*V

i rlhe plates 59, 6C) are provided with aliiied perforations adapted to register with Vone or` another of the perforations in the plate 58."

so that, a bolt 61 passed hrough the pertorations in the plates 58, 59, 60 may serve to lock the plate 58 in'hxcdrelation to they bracket 43,`thereby holding-the cross-coin necting rod i6 against endivisev movement.

The bolt 61vis mounted to move vertically, being held by the plates 59, 6() and by a bracket 62 secured tov the' upper side otl theV housing 4:2, as best shown in Fig. V8. VThe .iolt is moved ,endvvise by oi'.I a 63 mounted on a pivot Get' carried by the ybracket 62, as' shown in F Vand coii-Y nected with the upper end oi? said bolt. Thus;

the lever 63 and theother'iiarts of the locking mechanism are' all ssorted :the

of the machine, as is thelcasevvitli figures. Y 4 Y l So far as We are aware', Yvve f are theftirst lever L aXle 2&and are independent ot their-aine,A l Y the'alt'ers Y ynative locking mechanism shown in the otheiginthe art to provide a road machine `having `an endivise movable rear axle with -dirigible rear Wheels carried i by such rear axle and provided with means independent of the machine frame for steering said Wheels; also to provide means `independent of the frame for locking the wheels in the different positions to `which they may `be adjusted. j The claims hereinafter made directed to these features are therefore intended to he generic. i
