Definitions

  • This invention relates to a road roller having two front rollers arranged one behind the other, and two driving rollers arranged side by side at the rear ofthe road rolling machine.
  • the said front rollers are both turnable, so that each roller obtains a rolling movement.
  • the rear roller of the front rollers is so arranged as not to be displaced in a horizontal direction, that ,is to say, in the longitudinal direction of the roa rolling machine.
  • the foremost roller of the front rollers is steered by means of two bars driving a wheel fixed at the vertical shaft of said foremost roller, said bars being driven by means of a corresponding wheel, both of said wheels being connected by means of a strip that is turnably connected with two equi-positioned points, one at each wheel, while the connection of said strip with the foremost roller enables a longitudinal displacement of the strip, and moreover at such distance from the center of said foremost wheel that the distance is greater than the distance ofthe equi-positioned point of the other or rear wheelwith respect. to the center of said last mentioned wheel; said strip having a groove or slot guiding a pin connected to the vertical turning shaft of the rear rollerof the front rollers by means of an arm.
  • Figure 1 shows schematically a side view of the frame of a road rolling machine according to the invention.
  • Figure 2 shows a plan view of same.
  • Figure 3 shows also a plan view in which both steering front rollers are placed in a turned position while Patent expires November 30, 1965 '1 Claim. (01 94- 50)
  • Figure;4 shows a,longitudinal sectionof the rolling machine.
  • Figure Si a view in vertical section, taken on li ne 5 5, of Figure 1 looking in the direction of the arrows.

  • a ground roller 3 is mounted to rotate onthe axle 3a, which is supported by the e-shaped bracket 3b, swivelled at [3 to the horizontal plate 3d. carried bythe parallel side bars la and lb of themain frame.
  • a second ground roller 5 is mounted to rotate on the axle 5a, which issupported on the U-shaped bracket 57), swivelled to the horizontal plate 50,
  • Circular bearings 3m and 5m are interposed between bracket 3band plate 3d,

  • the wheel (5a is engaged by .adrlve chain or cable 9a, which also engages the sprocket or drive gear 9b, carried by the shaft 90, on which the hand wheel 9 is mounted.
  • the rotary motion ofthe sprocket or drive gear 9b will betransferred by the chain 9a to. the wheel l5a.
  • This will produce a longitudinal shifting motion on the parallel bars i2 and I M, and a longitudinal shifting motion on the intermediate bar 14, which will cause the wheel l3a to turn in the same direction that the wheel I5a is caused to turn. This will result in the turning of the bracket 3b and the roller 3 in a corresponding direction.
  • the intermediate bar 14 occupies the position shown in Figure 2, with the rollers 3 and 5 disposed in parallel relation to each other and at right angles to the main frame.
  • the wheel 15a is turned either to the right or to the left; the intermediatebar M will be displaced laterally from its normal central position, and this will cause the bar M to swing the pin 19 in an arc concentric to the axis 5d of the bracket 5?) of the roller 5, and thereby turn .the,
  • roller 5 in the same direction of turning produced on the roller 3, which may-be-non-parallel to the latter.
  • a horizontal shaft [6 is"mountedtto rotate on the main frame I, and is equipped on' its outer end with a hand wheel and inwardly thereof with a bevel gear Ilia, and; near the remaining end with a bevel gear I611.
  • the bevel It will be seen, therefore, that my invention provides means for increasing or reducing the spacing between the rollers 3 and 5, and of rotating both rollers from right-angular pressure positions, and of raising and lowering the wheels -4 and larelative to thegmain frame,
