  • This invention relates to road building machines and, more particularly, to road building machines having an adjustable working width.
  • finishing machines changes in the working width of the machine can be effected by modification of the width of the trailing part of the machine which contains the working elements.
  • the drive means, propulsion means, material handling devices, and control means are combined in a basic vehicle of fixed width. The vehicle travels over the substrate upon which the trailing working elements lay the surfacing material.
  • two separate side frames are provided with running gear sets, the side frames being connected exclusively by detachable elements.
  • the running gear sets of the side frames run outside the area upon which material is to be laid, i.e., on the right and left-hand sides of the roadway.
  • a road building machine having side frames mounted on running gear sets and provided with openings through which the connecting, working, and extension elements project on each side.
  • the connecting and working elements extend between the side frames and are arranged to be of adjustable working width by means of the extension elements.
  • Guides are provided on the connecting, working, and extension elements so that the working width may be adjusted and these elements thereupon clamped in the adjusted position by releasable fastenings.
  • the working width of the machine is independent of the dimensional gradation of the extensions, and, when the working width is being changed, the load-bearing cooperation of the elements of the machine is not lost at any stage of the process. It is therefore not necessary to provide separate temporary supports for the connecting and working elements. All that has to be done is to attach the extensions to the ends of their associated connecting and working elements on the outside of the side frames'of the machine and then, after the releasable fastenings have been slackened off,
  • the working elements and their extensions, as well as the connecting elements and their extensions, conveniently have the same circumferential cross section. This ensures that the elements will all fit the available open cross sections of the openings in the side frames.
  • the guides extend collinearly along the working elements and their extensions and collinearly along the connecting elements and their extensions. Connecting flanges are provided in such a way that they do not interfere with the continuity of the guides. These features permit the road building machine to be very conveniently adjusted to a different working width.
  • the running gear sets on the side frames can be swiveled about vertical axes.
  • the side frames may be moved on their running gear sets, while the connecting elements and extensions remain stationary, until the desired width has been established.
  • FIG. 1 is a diagrammatic front elevational representation of a road finishing machine according to the preferred embodiment of this invention.
  • FIG. 2 is a sectional view taken along the line II II in FIG. 1.
  • FIG. 3 shows part of the machine of FIGS. 1 and 2 during the process of increasing its working width.
  • FIG. 4 shows the same part of the machine as FIG. 3 at a later stage during the process of increasing its working width.
  • FIG. 5 is a cross-sectional view of one form of the joint between the connecting element and its extension shown in FIGS. 3 and 4.
  • FIG. 6 is a side view of the joint between the connecting element and its extension shown in FIG. 5.
  • a road finishing machine comprising two side frames 1 and 2, each provided with running gear sets 3 and 3'.
  • Connecting elements 4 and working elements 5 extend between and through side frames 1 and 2. It will be understood that a plurality of connecting elements 4 as well as a plurality of working elements 5 will be provided in such a machine. However, for the sake of clarity, only one connecting element 4 is actually shown in the drawing, and the two working elements 5 shown in the drawings are indicated as being a compacting beam 6 and a screed hopper 7.
  • Side frames 1 and 2 are of symmetrical construction and contain openings 8 through which the ends of connecting and working elements 4 and 5 project. Openings 8, as well as connecting and working elements 4 and 5, are fitted with guides 9 and 10, which are described in more detail below.
  • Side frames 1 and 2 are provided with fastening or fixing elements which cooperate with connecting elements 4 and working elements 5. These fastening elements permit side frames 1 and 2 and connecting and working elements 4 and to be rigidly fixed at any working width of the road building machine.
  • extensions 11 are associated with connecting elements 4. Extensions 11 are designed to match connecting elements 4 and can be attached thereto in order to lengthen them. Similarly, extensions 12 are designed to match working elements 5 and can be attached thereto in order to lengthen them.
  • extensions 11 and 12 are first attached to the corresponding connecting elements 4 and working elements 5 either on one or both sidesof the machine, but outside of the side frames 1 and 2. This is done by means of flange joints. At this stage, it is not necessary to detach side frames 1 and 2 from connecting elements 4. Consequently, it is also unnecessary to provide temporary support for the parts of the machine located between side frames 1 and 2.
  • FIG. 4 shows the arrangement after side frame 1 has been moved to the required overall width. All that remains to be done is to tighten the fastening elements on side frames 1 and 2 to reestablish rigid connections between the side frames and extensions 1 1 and 12. A reduction of the working width of the machine can be accomplished in an analogous manner.
  • Extensions l1 and 12 for lengthening connecting elements 4 and working elements 5 are always attached to or detached from the ends of their associated connecting and working elements on the outer sides of side frames 1 and 2 of the machine. This is possible because the middle portion of the machine need not be temporarily supported. The time needed for adjusting the working width of the machine is thus substantially shortened by the proposed form of construction.
  • FIGS. 5 and 6 illustrate an example of one particular joint between a connecting element 4 and its extension 11.
  • the two elements 4 and 11 are of substantially the same diameter, the connecting element 4 being tubular with guides comprising projections extending along the length thereof and projecting radially therefrom. Projections 10 are received in cooperating grooves 9 in an opening 8 of side frame 1.
  • Alternative guides e.g., slideways, slots, and other conventional means, may be employed.
  • a fastening element 13 in the form of a clamping screw is shown schematically in the drawing.
  • eccentric clamping means are particularly suitable for the described purpose of establishing a loadbearing fastening between the side frames 1 and 2 and the connecting and working elements 4 and 5.
  • Flange-type joints 14 and 14 are provided for attaching an extension element 11 to a connecting element 4. Naturally, projections 10 must extend along the length of extension 11 (as indicated by 10' in FIG. 6). The guides 10 of the extensions 12 for the working elements 5 also extend along the length of those extensions.
  • a road building machine of adjustable working width comprising side frames mounted on running gear sets that may be swiveled about vertical axes between a position permitting forward movement of the road building machine on the running gear sets and an other position permitting lateral movement of the side frames on the running gear sets to adjust the working width of the road building machine; connecting and working elements for spanning the distance between the side frames and projecting outwardly through openings in the side frames on each side of the road building machine; extension elements for attachment to end portions of the connecting and working elements that project outwardly from the openings in the side frames; the openings and the connecting, working, and extension elements having guideways to facilitate lateral movement of the side frames along the connecting, working, and extension elements to adjust the working width of the road building machine; and fastening means for clamping the side frames and the connecting and working elements or their respective extension elements together when the working width of the road building machine has been adjusted to a desired working width.
  • a road building machine of adjustable working width as in claim 2 wherein the guideways of the connecting, working, and extension elements are formed on the outer peripheral surfaces of those elements with the guideways of the connecting elements and their respective extension elements collinearly extending along the length thereof and with the guideways of the working elements and their respective extension elements collinearly extending along the length thereof, and wherein end portions of the connecting, working, and extension elements are provided with connecting flanges by which the connecting elements and their respective extension elements may be attached together without interfering with the continuity of the guideways formed on the outer peripheral surfaces thereof and the working elements and their respective extension elements may be attached together without interfering with the continuity of the guideways formed on the outer peripheral surfaces thereof.
  • working elements and their respective extension elements may be attached together without interfering with the continuity of the guideways formed on the outer peripheral surfaces thereof.
