or webs each with a lower outturned base flange and an upper outturned tread fiange. The latter flange has heretofore been disposed at right angles to the web flange. Consequently when a surfacing implement or tool is employed in forming the crown of the road, it runs upon the oute'r edge of the tread fiange. The result is that the road surface is defined by the outer edges of the tread fianges of the opposite forms with a resultant excessive thickness.
The object of the present invention is to overcome this objection by so forming the tread fiange that the inner edges of the form are the starting points for the roadway surface. Nhen it is considered that many miles of roadway are produced,the resultant saving in material is important. And besides, a better upper corner is produced.
In the accompanying drawings:
Figure 1 is a sectional perspective view of portions of a roadway formed with the. completed road bed therein,
Figure 2 is a detail sectional view on an enlarged scale showing the improved structure in full lines and the original structure in dotted lines in order to indicate the resultant benefits of the former.
The form members are generally designated by the reference numeral 3, and each consists of a vertical wall or web et, with an outstanding base flange 5 and an outstanding tread or guide flange 6 that may be reenforced by a downturned rib 7. It will be understood that these may be made in sections, and connected by any suitable means, as for example, those disclosed in my above mentioned patents. The tread or guide flange 6 of each meniher, instead of being at right angles, has an outward and downward inclination, preferably at substantially the angle of the surface of the crown of the roadway to be constructed, as llustrated in full lines in Figure 2. In other words, the upper surface 8 of the guide or tread fiange 6 is substantially a continuation of the upper surface 9 of the concrete or other roadway. It will thus be evident that when a surfacing tool or implement is moved along opposite guide fianges 6 the surface 9 of the roadway will be at the level of the inner edges of the fianges 6, or in other words, constitute continuations of the upper surfaces thereof, whereas with the forner Construction, as indicated in dotted lines in Figure 2, when the upper face 8' is at right angles to the body 4, the concrete surface 9 starts at the outer edge of the fiange, and an increase in the thickness of the road bed is thus produced, which makes a decided increase in the amount of material used, particularly on long stretches. Besides it leaves outstanding flanges overhanging and extending beyond the body of the road bed.
F rom the foregoing, it is thought that the constructlon, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of Construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
hat I claim is:
1. A form for crowned concrete roadways and the like comprising spaced concrete confining side walls, having oppositely outstanding guide or track flanges along their upper edges, the said fianges of the two side walls having their upper faces inclning outwardly and downwardly to correspond substantially to the erowned surface of the roadway. i
2. A form rail having an upper ,beveled fiange.
3. A form rail having a tread fiange sloping from the rail web.
4. A form rail having a Web and an upper fiange, with said flange so formed as to pro vide a single line of wheel contact directly above the web.
In testimony whereof, I affix my signature.
FRANCIS o. HELTZEL.
