ings.

This nvention comprehends certain new and useful improvements" ii- .road making and repairing machines, and relates particu-v larly to scrapers of the wheeled type;

The invention has for its .primary; object afdurable and efiicientconstruction ofnmchine ofjthis character embodyinga novel and useful construction and arrangement of theparts of the blade elevating;and'-lower ing mechanism, and. a novel andUusefu-l con.

struction anda'rr'ange nent-of the p'arts're- -lating to the means for tilting the blade or V scoop to dump the same.

Afurther object of the III-VGHiZlOIILlS. a road scraping. machine in: which the operating levers are all arranged. within conven ent,

'ivhichisf fulof' iits' ends"; uni n crumed intermediate lower ends of the bars .19 are-connected to vertically disposed link rods 20, and the connected to tlie'outer arms 6 .nearthe fo"- ward ends of the latter, whereby it will be understood that when-the lever is manipulated and moved in a direction 'to press the arms 6 and 8 will be moved downwardly and th scoop 7 will be brought down to the downwardly upon the suspension bars 19,

ground and to its operative position, where it may be held by the' en agement of the 2 0 detent of the hand lever with the quadrant !18. Just as soon as the detent is released the springs 14 will be'permitted to 'act to again raise the scoop to its inoperative po sition. To assist in guiding the arts in these movementsand tofacilitate t e operation, substantially Uesha-ped brackets 21 are connected to the bars 19 and link rods 20 at their points of juncture, the side members 22 of said brackets extending outwvardly in a lateral direction and supporting rollers 23 which are adapted to roll along the outer faces of longitudinally spaced braces Q lthat form part of the main framework 1 and that extend forwardly and thence upwardly and inwardly where they are connected at theirupper ends to one of the longitudinal upper sills 25 of the framework, and the shaft-26 which carries these rollers is preferably formed at. its middle,

between said rollers,.with a block 27 through V which extends the rod 28.which .fastens the 'bracket 21 to the link rods and suspension bars,'tlie rod 28 passing between the braces 24 mentioned. The scoop 7 pivotally mounted at its'ends,]as at29, tothe forward ends of the outer arms'6whereby it may tilt about a transversely extending horizontal axis in order to dump its contents, preferably after it has been raised to its elevated and inoperative position, and to tilt and dump the scoop-it is in the present'embodiment of the invention, provided at an intermediate oint with an upwardly extending apertured ear 30; links 31 are pivotally on nected at one end to fthejsaid car on oppo-' site sides ofthe same;- and a hand lever 32 is pivotally connected at its lower end to the forward ends of said links, said lever being fulcrumed intermediate of its ends-on one of the. longitudinally extending sills or beams of the framework, and like the lever 16, being disposed in convenient proximity to the drivers seat 33. V The lever 32 is pros ed with a spring pressed detent designed into;- engagement with a toothed quadrant 4 nection with the accompanying drawings 3 lower ends of said-link rods arepivotally pul Preferably the lever 32 has its lower a-iiii' movable in a guide slot 35 formed in a b51 36 which is secured in the framework. a From the foregoing description in conthe operation of my improved road machine will be apparent. In the practical use of thema'c'hine, as it s drawn along the road the operator may easily move the scraper downto its operative position in contact with the ground byv U ling upward upon the forward or handle end of the lever "16, whereby the arms 6 ,and 8, will be swung downwardly onthe rear axle 4;,and the contra'etile'springs 14 so 7 stretched. When-the parts-have been ad- -justed to the required positions, the spring pressed detent of. thelex 15*is' engaged with a registering'notch or tooth of the quadrantlS. When it is desired to dump as the scoop, it is'preferably first raised to its inoperative position and the lever 32 is inanipulated. .As the operator pulls 'rear-l wardly upon the upper or handle end of the lever 32 it is obvious that, through the instrumentality of'the links 31, the scoop 7 will be tilted and its rear edge raised and front or blade edge lowered, whereby the soil and the like will. be discharged therefrom. a Y

\Vhile the accompanying drawings illustrate what I believe to be the preferredembodiment of my invention, it is to be understood that theinvention is not limited thereto, but thatv various changes may be made in the details of construction. without departing from 't-llQySOOPB-Of the invention. as defined in the appended claims.

What is claimed is; 3 r 1'. A machine of the character described, comprising a wheel supported framlework, including a rear axle, scoop supportin'g'arins pivotally mounted upon said axle, a trans? versely extending bar connected to said ried by said arms, contractile springs'connected at their'lower ends to said ba j'and 1 extending upwardly and rearwardly therefrom and connected at their upper ends to the framework, a hand lever mounted. on top of the framework,suspension bars connected to said lever and extendingout wardly and downwardly therefrom, and link rods connecting the lower ends of said suspension bars to the scoop supporting arms.

2. A machineof the character described, comprising a wheel supported frame, including a rearaxle, scoop supporting arms pivotally mounted at their rear ends on said axle and extending forwardly therefrom, a transverse brace bar connecting said arms together, contractile springs connected to said'bar and extending upwardly therefrom and connected at their upper ends tothe cally movable link rods connecting the lower ends of the suspension bars to said arms,

[l -shaped brackets connected to said suspens1on bars and link rods, rollers journaled in said brackets and movable upon the frame- .work in the upward and downward move ments of said link rods, and a scoop carried by said arms.

3. A machineof the character described,

1 comprising a wheel supported framework including a rear axle, scoop supporting arms pivotally mounted at their rear ends on said axle, and extending forwardly therefrom, a

' shafts -mounted in said brackets and provided intermediate of their ends with lugs, and rollers mounted on said shafts on opposite sides of said blocks and movable upon the framework, the connec' 'ons between the link rods and the brackets extending outwardly through said blocks and connected thereto, substantially as described.

4. A machine of the character described, comprising a wheel supported framework, including a rear axle, scoop supporting arms pivotally mounted at their lower, ends on said axle and extending forwardly therefrom, a scoop carried by said .arms, a hand lever mounted on top of the framework, suspension bars pivotally connected at one end of the lever and extending laterally and downwardly therefrom, link rods pivotally connecting the lower outer ends of said suspension bars to said arms, a support carried by said arms, brackets, shafts mounted in said brackets, rollers journaled on said shafts, the shafts being formed between said rollers with blocks, and connecting rods passing through the suspension bars and link rods and also through said blocks and connected to the latter, as and for the purpose set forth.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
