THE NORRIS PETERS (20.. PHOTO-LITHQ, WASHING ION D. c
CUTTING-DISK FOB. METAL-CUTTING- MACHINES.
To all whom it may concern Be it known that I, HANS HEYNAU, of Nuremberg, Bavaria, Germany, I have invented an Improvement in or Relating to Cutting-Disks for l\.[etal-Cutting Machines,
of which the following description, in connection with the accompanying drawing, is a specification.
This invention relates to an improvement in that class of cutting disks for metal cutting machines where the rim of the disk is on its whole circumference continuously smooth and grooved as described in my specification Serial No. 771,455, filed June 3, 1.913.
The object of that inventionwas to reduce or entirely avoid the formation of the burs which heretofore appeared at the cutting point in the working-piece on both sides of the disk when grooveless disks were used. However, when parts are severed which subsequently are to be welded, or end pieces are removed which will be wasted, it is sufficient to make one side of the cut smooth, while 7 the formation of bur on the other side has no disturbing eifect. In View of these considerations the rim of the cutting disk is beveled to one side according to this invention.
Several constructions of disks according to this invention are illustrated in the accompanying drawing.
Figures 1 to 3 are sections and Fig. 4 an elevation. Fig. 1 shows a plain disk a, Fig. 2 a disk Z2 which is wedge shaped in section and is widest at its periphery, and l ziig. 3 a disk 0 with a beaded andthickened e ge.
Specification of Letters Patent.
Patented Mar. 2, 1915.
Application-filed January 15, 1914. Serial No. 812,301;
' The rim (1 of each disk slopes toward one side. One edge of the disk is thus made to project, and it penetrates first into the work to be cut, and always cuts deeper therein than the other edge. Thus during the cutting and feeding of the disk, the material in cut becomes incandescent, and in as far as it is'not burnt and forced forward, is pressed back by the sloping edge of the disk, and therefore appears at one side of the cut as a bur, while the other side of the cut is smooth and free from bur.
The new disk construction is simpler than that described inthe prior specification, and completely fulfils its object where cuts free from bur on one side only, are requircd.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
- 1. A high speed rotary cutting disk for.
severing metal, said disk being provided with an edge sloping in one direction only.
2. A high speed rotary cutting disk provided with an edge sloping in one direction only, said disk gradually increasing in thickness from the center toward the edge.
8. A high speed rotary cutting disk, provided with a strengthened peripheral edge inclined in one direction only.
In testimony whereof I affix my signature in presence of two witnesses.
