ROAD MACHINE, 1

Application filed July 23, 1931. serial No. 552,715.

The present invention relates to new and useful improvements in road machines and has for its primary object to provide, in a manner as hereinafter set forth, a device of 1 this character embodying a novel construction, combination and arrangement of parts through the medium of which a shoulder may be formed adjacent a highway and a bank which may be adjacent said highway may be simultaneously graded or sloped.

Another important object of the invention is to provide a road machine of the aforementioned type embodying a novel construction and arrangement whereby the endless scrap- 1 er unit constituting an essential portion of the invention may beexpeditiously' adjusted as desired for sloping the bank at any desired inclination and for forming the shoulder as desired. j 7 Other objects of the invention are to provide a road machine of the character described which will be simple in construction, strong, durable, elficient and reliable in operation and which may be manufactured at 2.5 low cost.

All of the foregoing and still further-objects and advantagesof the invention will become apparent from a study of the following specification, taken in connection with T3 the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views,

and wherein j Figure 1 is a view in rear elevation of a i 1 portion of the machine.

Figure 1 is a vlew in rear elevation showing the portion of the'machine which is omitted from Figure 1 Figure 2 is a view in top plan of the road machine. 7

Figure 3 is a detail view showing the position of one of the scraper blades.

Figure dis a view partially in bottom plan and partially in section showing the means for adjusting'the endless scraper.

Figure 5 is a view in elevation showing the means for adjusting the endless scraper. Referring now to the drawings in detail, it will be seen that the reference numerall if? designates a cab which is mounted for rota "connected to the members 14: and ofthe tion on the supporting wheels or the equivalent 2 by a turn table 3. A chassis 4 is disposed between'the cab 1 and theturn table 3.

The reference numeral 5 designates an intergial combustion engine located within the ca 1.

Mounted for swinging movement in a vertical plane on one end of the frame l is a boom 6 including side portions or bars, said boom havin the downward extension 7 at its inner en The boom 6 is raised or lowered through the medium of a cable 8 having one end anchored, as at 9, said cable being trained over pulleys l0 and 11 and being windable on a drum12 which is operatively connected to the engine 5 for actuation thereby. As clearly seen, the pulley 10 is mounted on the free end portion of the boom 6 and the pulley 11 is mounted on the cab 1.

The boom 6 operatively supports an endless scraper designated generally by the ref erence numeral 13, said scraper 13 including a pair of comparatively short inn-er side members 14 hingedly' mounted between the lower end portions of the extension 7 of the II boom 6 and a pair of comparatively long outer side members'15. pivotally connected .to the members 14. Sprockets 16 are provided in pairs between the membersl l and 15 of the endless scraper 13 and said sprockets are operatively engaged with the lower flights of the endless chains 17. Diagonally disposed scraperblades 18 are mounted on the chains 17 for engagement with the ground. The leading end of the blades 18 may be toothed to facilitate cutting through theground when the machine is in operation. As clearly'seen in Figure 1 of the drawings, the upper end of theendless scraper 13 is slidably supported on the boom 6, I as indicated at 19. i i

A substantially inverted 'U-shaped bracket 20 extends between the side members'or bars constituting the boom 6 and extending between the side portions of saidbracket is a bar 21. A screw shaft 22 is operable through the bar 21"and thebracket 20 and has its lower end rotatably. connected to" a yoke 23. The lower end of the yoke 23 is pivotally endless scraper 13 at the hinged joint of said members. A worm gear 24 is threadedly mounted on the screw shaft 22 between the bracket 20 and the bar 21. Bearings 25 are provided on the bracket 20 and journaled in said bearings is a worm 26 which is operatively engaged with the worm gear 24. A telescopic sectional shaft 27 has one end connected with the worm 26 by a universal joint 28 and mounted on the other end of the shaft 27 and located within the cab 1 is an actuating wheel 29. By actuating the worm gear 24 in a manner to raise or lower the yoke 23, the angle between the members 14 and 15 of the endless scraper 13 may be varied as desired'for forming the shoulder and for sloping the bank at any desired inclination. The reference numeral 30 designates a substantially inverted U-shaped bracket mounted on the boom 6 at the inn-er or hinged end of said boom. A screw shaft 31 is operable through the bracket 30 and has rotatably connected to its lower end a oke similar to the yoke 23 which, in turn, 1s connected at its lower end to the inner ends of the members 14. The innermost pair of the sprockets 16 are fixed on a shaft which extends through vertical slots 32 provided therefor in the depending portions 7 of the boom 6. A worm gear 33 is operatively mounted on the screw shaft 31 and, when actuated, constitutes means for raising and lowering the inner end of the endless scraper 13. A sectional telescopic shaft 34 has one end connected by a universal joint similar to the joint 28 to a worm similar to the worm 26 which is operatively engaged with the worm gear 33. Fixed on the other end of the shaft 34 within the cab 1 is an actuating hand wheel 35. Extending downwardly and inwardly from the inner end portions of the members 14 of the endless scraper 13 is a pair of arms 36 which support an inclined chute 37 It will be noted that the inner end portions of the members 14 extend upwardly at a slight angle sufiicient to raise the scraper blades 18 in a manner to clear the lower end of the chute 37. An endless conveyor 38 is supported by any suitable means as at 39, on the frame 4, said endless conveyor extending forwardly and upwardly and having its lower end portion disposed transversely beneath the upper or discharge end of the chute 37 to receive the material from said chute. The conveyor 38 is mounted for vertical swinging movement and is adjustable through the medium of a cable 40 trained over suitable pulleys 41 and operatively connected with the upper end of the conveyor, said cable 40 being windable also on the drum 12. The conveyor 38 constitutes means for loading the material into a vehicle located forwardly of the machine.

The reference numeral 42 designates a. vertically disposed shaft mounted on the depending extension 7 of the boom 6 and having splined on its lower portion a beveled gear fixed on one of the projecting end portions of the shaft which drives the chains 17. A shaft 44 is mounted on the frame 4 and has one end operatively connected to the shaft 42 by suitable gears designated generally at 45. The other end of the shaft 44 is operatively connected to the transmission of the engine 5 by a suitable shaft and gear connection designated generally by the reference numeral 46. The endless conveyor 38 is operatively connected with an intermediate portion of the shaft 44 through the medium of a chain and sprocket connection designated generally by the reference numeral 47. A plate 48 is mounted closely adjacent the rear side of the endless scraper 13 to prevent dirt from spilling over the graded slope or shoulder.

When the machine is in use, the diagonally disposed blades 18 travel beneath the sprocket wheels 16 and scrape the dirt from the slope and shoulder adjacent the highway over the chute 37 and deposit the same on to the endless conveyor 38 which carries the material forwardly and upwardly and deposits said same in a vehicle located beneath the discharge end of the conveyor. By operating the

hand wheels

29 and 35 the inclination of the shoulder and the slope may be regulated as desired and, as before stated, the entire endless scraper may be swung upwardly or downwardly through the medium of the cable 8 connected to the boom 6. An important feature of the invention resides in the construction and arrangement whereby the angle of the endless scraper may be varied as desired to form the shoulder or the slope at any inclination which may be desired.

It is believed that the many advantages of a road .machine constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and de scribed, it is to be understood that changes in the details of construction and in the combi nation and arrangement of partsmay be resorted to which will fall within the scope of the invention as claimed.
