  • Her ETakaza FOOT FOR COMPACTING ROLLER This invention is concerned with the problem of compacting loose material such as earth, sand and dumped refuse and trash, by means of heavy roller equipped machines.
  • One of the attributes of a good compactor foot is a selfcleaning shape so that despite the relatively close spacing of the feet on the roller required to assure that the weight of the compacting machine will be borne by the feet and not the surface of the roller from which they protrude, the material being compacted does not become lodged between the feet and any such material which does tend to adhere to the roller is easily cleared therefrom by stationary cleaning fingers that project between axially adjacent feet.
  • a good compactor foot also should have a tapered shape with a decreasing cross section towards the tip so that it sinks relatively deeply into the material when the density thereof is low, enabling the roller to effect rather rapid preliminary densification, and then as the density of the material increases, it sinks in less and less deeply. Accordingly at each successive pass the foot presents a smaller surface area to the material to insure that in the final few passes the material will be subjected to the highest possible compacting force per unit area obtainable with a given machine with the result that the maximum possible compaction is achieved in a relatively short time.
  • Another very important requirement of a good compactor foot is that it leave the material being compacted without disturbing the already compacted material. Not only does this capability assure against objectionable shearing of the compacted material, but it also gives 'the foot the desired selfcleaning characteristics, with the result that less power is needed to propel the machine across the ground.
  • the present invention provides a compactor foot that satisfies all of the aforesaid requirements.
  • the invention is premised upon the recognition that the tendency for material to lodge between the feet of a footed roller can be substantially overcome by so shaping the feet that the included angle between all surfaces of adjacent feet is greater than the angle of friction of the material when it is in motion and the combination of this principle with a recognition of the advantages of involute curves as applied to the shape of a roller foot.
  • FIG. 1 is a perspective view of a portion of a compactor roller that is provided with feet embodying the principles of this invention
  • FIG. 2 is an end view of a portion of the roller illustrating several of the feet thereon in side elevation and depicting the manner in which the feet enter and leave the ground or other material being compacted;
  • FIG. 3 is a sectional view through FIG. 2 on theplane of the line 3-3 to illustrate the profile of the feet as viewed from either edge thereof;
  • FIGS. 4 and 5 are, respectively, a side view and a plan view, both on an enlarged scale illustrating how curved lines that are substantially involutes generated from a base circle having a radius substantially no larger than that of the roller surface are employed to govern or produce the fore and aft shaft of the feet in that embodiment of the invention shown in FIGS. 1-4;
  • FIG. 6 is a side view, on a smaller scale, of a foot like that shown in FlG. 4 but having an end surface of slightly modified shape;
  • FIGS. 7, 8, and 9 are respectively a side view, an edge view and a plan view of a foot which embodies the advantageous features of this invention but is especially well adapted for sanitary land fill usage wherein trash and rubbish and all forms of loose material must be broken up;
  • FIG. 10 is a diagrammatic view illustrating the manner in which the fore and aft shape of the foot is derived.
  • each roller comprises a cylinder or drum mounted on one of the rubber tired wheels 7 of the compacting machine, all four of which are usually power driven to afford traction for the vehicle.
  • the feet 6 are arranged in several ranks that extend circum-.
  • the roller ferentially around the roller and in several rows that extend parallel to the roller axis.
  • the feet in each row are in axially offset relation to the feet in the adjacent rows, and the spacing between circumferentially adjacent feet is less than the circumferential width of a foot.
  • Each foot has a longitudinal axis 9 which coincides with a radial to the roller axis as indicated in FIG. 4.
  • the axis 9 also coincides with and defines the intersection of two planes of symmetry of the foot.
  • One of these planes, designated by the line 10 in FIG. 5, is normal to the roller axis and the other, designated by the line 11 in FIG. 5 contains the roller axis.
  • the shape of the base portion of the foot that is, the portion of the foot which is nearest to the cylindrical surface of the roller proper, for any material that sticks to this portion of the foot tends to pick up additional material by adhesion and thus start a build-up.
  • the base portion of the foot of this invention is substantially elliptical in cross section, on any plane normal to the longitudinal axis 9, as best seen in FIG. 5.
  • the major axis of the ellipse coincides with the plane 10 that is normal to the roller axis and lies on the longitudinal axis of the foot;
  • the minor axis of the ellipse coincides with the plate 11 that lies on or contains both the longitudinal axis of the foot and the roller axis.
  • the dimensions of the foot on the plane of the major axis of the ellipse are between two and three times the dimensions thereof on the plane of the minor axis of the ellipse.
  • the height of the foot should be at least one-half the maximum width of the foot at the base thereof where it is affixed to the roller.
  • Each foot tapers radially outwardly of the roller towards its longitudinal axis 9, with all opposite surfaces thereof converging towards one another. Even at the junction of the foot with theroller, the surfaces of the foot are tapered. Furthermore, along the height of the foot, the taper is increasingly greater.
  • the shape of the foot is such that every plane through the foot that is normal to the roller axis defines at its intersection with the foot surface a pair of opposite curved lines that are substantially involutes generated from a circle lying on the plate and concentric with the roller, which circle has a radius less than or at least not greater than that of the roller.
  • a number of these curved lines or involutes" are depicted in FIG. 4 where they are designated a, b, c, d and e, and their corresponding planes depicted in FIG. 5 are identified pa, pb, pc, pd and pe.
  • the curved surface-defining lines a, b, c, etc. should be true involutes generated from the base circle but, in practice, they maybe uniform radius curves which closely approximate true involutes. This is done to facilitate the making of the pattern for the feet.
  • the radius of the base circle determines the angle between the leading and trailing surfaces of the foot, on all planes intersecting the foot and normal to the roller axis, and the respective radials from the roller axis that lie on said planes and pass through the junctions of the foot surface with the surface of the roller. Hence, the determination of that radius begins with identification of the minimum acceptable angle between those foot surfaces and said radials. That angle is governed by the coefficient of friction between the foot surface and the material to be compacted.
  • the coefficient of friction between an average foot surface and earth, sand, gravel and the like ranges between 0.25 and 0.36; and, for extreme conditions, it can be taken conservatively as 0.40.
  • the angle whose tangent is 0.40 (and which angle will be identified hereinafter as the friction angle") is 21 48. Accordingly, the aforesaid angle between the surfaces of the feet and the radials passing through the intersections of those surfaces with the roller surface'should not be less than I05 54', which is one-half the friction angle.
  • 0-F is a radial from the center of the roller which, at point P, passes through the intersection of the cylindrical surface of the roller with the surface of the foot, which may be its extreme leading or trailing edge surface or the intersection with the surface of the foot of any plane normal to the roller axis and passing through the foot.
  • a tangent to the foot surface must be at an angle E to 1 the radial 0-F of at least 10 54, which as already noted is one-half the aforesaid friction angle. That tangent is designated by A-B.
  • the required radius of the base circle can also be obtained by trigonometry from the relationship:
  • the spacing of the feet on the roller also has a bearing upon the shape of the feet.
  • the spacing of the feet In order to assure effective compaction for a wide range of materials, the spacing of the feet must be proportioned to the size of the feet and the diameter of the drum. Under no circumstances, however, should the spacing between the feet be such-that the included angle between their nearest surfaces is less than the aforesaid friction angle. As long as this requirement is met, the material will not tend to stick to the feet.
  • the leading and trailing surfaces of the feet that is, those surfaces thereof which are at the ends of the ellipse, should be relatively blunt. But such blunt leading and trailing surfaces have been found to require the outer portions 12 of the sides of the feet to be slabbed off, as shown in FIG. 4 especially where the feet are arranged side-by-side.
  • the feet are hollow, especially if they are relatively large, as for instance twelve inches wide and eight inches high.
  • the outer ends of the feet are then formed by V-shaped pads 13 which are welded as at 14 to the feet.
  • the pads to the feet both have adjacent edge portions thereof chamfered to define weld pockets or channels which are filled by the welds 14.
  • the bottom edge of the base of the foot which fits against the cylindrical surface of the roller has its outer margin chamfered at intervals to receive the welds 15 by which the foot is secured to the roller.
  • the pad 13 may have a shape such as shown in FIG. 6 wherein the outer surface thereof has substantial area and is curved and concentric to the roller axis to provide greater support and less surface disturbance with minimum penetration.
  • the modified embodiment of the invention illustrated in FIGS. 7, 8, and 9 is especially well adapted for sanitary land fill compaction in which it is necessary to cut and break up trash and rubbish'which may be strewn over the area to be compacted.
  • the feet 20 (FIGS. 7, 8 and 9) have relatively sharp leading and trailing edges 21 which result from having both curved side faces 22 of the feet continue uninterruptedly to the leading and trailing edges 21 of the feet.
  • the curvature of the side faces, as before, is such that all planes through the foot and normal to the roller axis are defined in part by opposite curved lines (a, b, 0, etc. in FIG.
  • I which are essentially involutes generated from a base circle the radius of which in this case is quite a bit smaller than that of the roller surface.
  • the involute lines of the leading half of the foot meet those of the trailing half on the transverse plane of symmetry designated by the line 11 in FIGS. 7 and 8 and as a result the opposite side faces of the foot have fairly well defined ridges 23 dividing the leading half of the side faces from the trailing half thereof.
  • the foot 20 is hollow, its top or outer end is an integral part of the foot rather than a separate welded-on pad; but again the outer surface is formed by two flat faces 24 I disposed at an obtuse angle to one another.
  • this invention provides a foot for a compacting roller that is highly efficient in compact ing loose material, has good cutting and crushing action on bulky material which might tend to form voids, and is substantially self-cleaning.
  • each foot having a longitudinal axis which is substantially radial to the drum axis, the foot being symmetrical to a pair of planes which lie on and intersect at said longitudinal axis, one of which planes lies on the axis of the drum and the other of which is normal to said drum axis;
  • each of the feet being tapered radi ally outwardly of the drum towards the longitudinal axis thereof so that all portions of the surface of any one foot are divergent to the surfaces of its adjacent feet, the angle between opposing surfaces of adjacent feet being at least as large as the angle of friction of material to be compacted by the roller;
  • each foot being so shaped as to be substantially elliptical on planes normal to the longitudinal axis of the foot, the major axis of the ellipse lying on said plane which is normal to the drum axis;
  • each foot being further so shaped that every plane through the foot and normal to the drum axis intersectsthe surface of the base portion of the foot on lines that are substantially uniform curves which closely approximate true'involutes generated from a base circle concentric with the roller and having a radius 2.
  • a compacting foot for a cylindrical soil compacting roller that has a predetermined radius, said foot having a longitudinal axis and being symmetrical to each of a first and a second plane that are perpendicular to one another and lie on said longitudinal axis, said foot being adapted for installation on the roller with a curved base surface on the foot matingly engaging the cylindrical surface of the roller and with said first plane normal to the roller axis and said second plane lying on the roller axis, said foot having a shape which is further' characterized by:
  • the base portion of the foot being of substantially elliptical cross section on planes that are perpendicular to both said first and said second plane, with the major axis of the ellipse coinciding with the first plane;
  • the compacting foot of claim 2 further characterized in that the outer end portion of the foot is formed by a pad which is initially separate from the foot but is welded thereto.
  • the compacting foot of claim 2 further characterized in that the outer end of the foot is defined by a pair of obtusely divergent flat surfaces which meet along a ridge that is parallel to the minor axis of the ellipse and that lies on said second plane of so that said ridge forms the outermost boundary of the foot.
  • the compacting foot of claim 6 further characterized in that the elliptical cross sectional shape of the foot is such that the ends of the ellipse are of small radius, so that the leading and trailing edges of the foot are relatively sharp.
  • the compacting foot of claim 2 further characterized in that on each of said planes through the foot, the angle between a radius of the roller that intersects its surface at the junction point of the surfaces of the foot and roller, and a line that passes through said junction point and is perpendicular to the radius of the curved line formed by the intersection of said plane through the foot with the foot surface, is .not less than one-half the friction angle of the material to be compacted.
