ROLLING COLTER.
SPECIFICATION forming part of Letters Patent No. 250,249, dated November 29, 1881.- Application filed April 13, 1881. (No model.)
To all whom it may concern Be it known that I, DAVID W. HUGHES, of Hamilton, Butler county, Ohio, haveinvented certain new and useful Improvements in Rolling Uolters, of which the following is a specification.
This invention relates to the form of rolling colters, to the form of material used in their manufacture, and to the process of manufacture; and it consists in forming colter-di'sksin polygonal shape; in forming such polygonal colters of triangles attached to each other at the center rigidly; in forming such triangles from bars of metal having chamfered edges; in cutting the triangles from the bar in such manner as to leave complete polygons, and in details of central fastening, as herein set forth.
In the accompanying drawings, Figure 1 shows a bar of disk material and method of cutting out the triangles. Fig.2 shows similar bar out for triangles only. Fig. 3shows side ofcomplete colter with one flange removed. Fig. 4 shows method of doweling triangles to clamping-flange, and Fig. 5 is an edge view ofcomplete colter.
In Fig. 3 the colter-disk D is formed with polygonal sides M, having chamfered edges B. The sides Mbein g straight permit the operation of grinding, 850., to be carried on with a simplicity and cheapness of manipulation not attainable in any of the usual forms of colters which have circular or serrated peripheries, and the prominent angles thus formed are found to be a great advantage in the penetratiu goperation of the colter. The polygonal disk is made up of sections 0 in the form of triangles rigidly bound together at the center by being attached to or by one or more flanges, as shown.
I is a permanent flange on the usual hub, E. The triangles may, if desired, be riveted directly to this flange, and thus complete the structure; but in practice it is best to use the usual loose flange, K, and to clamp the triangles firmly between the two flanges.
In Fig. 3, F F F are bolts passing through flanges and colter-disk at the alternate points of juncture between triangles, as shown. All
of the triangles thus become acted upon by half their number of bolts, the bolts F not only clamping the parts, but also doweling all the triangles.
G G G are bolts passing through flanges and triangles, the triangles being alternate ones only, the intermediate triangles being held by dowels H H H, cast on the flange, as shown in Fig. 4. The number of such bolts is but half the number of triangles. This method of formiug the colter-disk is of course applicable to circular or serrated disks as well as polygonal ones.
In Fig. l, Ais abaror slab of metal, having both edges chamfered, as at B. Eq uilateral triangles 0 cut from this slab with their apexes opposed and joined, as clearly shown, furnish material for sectional colters, the cutting-edges of the sections being formed by the chamfered edges of the slab, and the portion of the slab left between the triangles forms a hexagonal colter-disk with two of its cutting-edges already chamfered. In Fig. 3 the sections are cut as shown, and all the material is utilized as triangles with ready formed chamfered edges. There is no waste of material in this process of manufacture.
It will at once be seen that, aside from the special advantages offered by a polygonal form generally, the hexagonal form yields peculiar advantages, as shown in Fig. 1, and that the process of manufacture involving a two-edged slab is applicable to all polygonal shapes.
Rolling colters constructed with arc-shaped knives or indentations and having propellingpointson theircuttiug-edgeshave been used and are not claimed by me; nordoI claim the mode of forming colters by attaching sections independent of each other to a central piece.
I claim as my invention-- 1. A rolling-colter having the form of a regularpolygon bounded by unbroken right lines.
2. A rolling colter having the form of a regular hexagon bounded by unbroken rightlines.
3. Arollingcolterformed of sections set with their contiguous edges abutting, and rigidly united to a central flange.
4. A rolling colter formed of separate sections united to central flanges by means of bolts in alternate sections and dowels in intermediate sections.
5. A-polygonal rolling colter-disk formed from a slab having a chamfered edge.
6. Ahexagonal rolling colter-disk formed from a slab having each edge chamfered.
7. Sectionsfor polygonal colters of triangular form with one angular side chamfered.
8. Sections for hexagonal colters in the form of equilateral triangles with one angular side chain fered.
9. Sections for polygonal rolling colters formed from a slab having a chamfered edge.
10. Sections for polygonal rolling colters formed from a slab having both edges chainfered.
11. Sections for hexagonal colters formed from a slab having both edges chamfered.
12. The process of forming colters which consists in preparing a slab with suitable edges, cutting sections from the edge of such slab, and uniting such sections firmly withv a central flange.
13. The process of forming colters which consists in preparing a slab with suitable edges, cutting hexagons from such slab in the manner shown and described, and uniting the sectional scrap resulting with a central flange to produce a polygonal disk.
