OF NUREMIBERG, GERMANY.
ROTATING DISK FOR METAL-DIVIDING MACHINES.
Specification of Letters Patent.
Patented Oct. 1, 1912.
Application filed July 5, 1911. Serial No. 636,942. Y
To all whom it may concern:
Be it known that I, HANS HEYNAU, of Nuremberg, Bavaria, Germany, have invented an Improvement in Rotating Disks for Metal-Dividing Machines, of which the following description, in connection with the accompanying drawing, is a specification.
The invention relates to rotating disks for metal-dividing-machines.
Attempts have already been made to employ rapidly rotating smooth metallic disks to divide metal, but the heat produced by the extreme rapidity of revolution of the sweat fast in the work beresult could be accomdisadvantage attendin disks was that the edge, heated, turned over upon itself, so that the desired effect was also not attained. The present invention 'avoids these disadvantages by thickening or broadening the edge of the disk in any suitable manner. The disk does not then bend in cutting nor does it sweat into the work.
In the drawings, Figure l is an end view of a machine showing the application of my invention thereto. Fig. 2 is a side view thereof. Fig. 3 is an enlarged sectional view of one form of my invention. Fig. 4 is an edge elevation of the modified form of the invention. Fig. 5 is a sectional view of the form shown in Fig. 4.
Figs. 1 and 2 show the manner in which the disk is disposed in a machine. The disk Z) is of ordinary sheet-iron, the edge being thickened in any manner as shown in Figs. 3 to 5, the whole being mounted on the shaft -d and the latter rotated rapidly by means of the pulley he operation of the appliance is extremely simple. The material to be sepaand advanced toward the disk -5- which is rotated at a circumferential speed of about seventy meters (two hundred and thirty feet) a second. The friction. produced occasions such a heat as to cause the material to glow at the point of contact, so that it is partly consumed and partly pressed aside by the advance of the disk. As the edge of the disk is broader and thicker than the more central parts, the disk is continually surrounded by air and so far cooled by this means that it does not sweat fast in the work fore the desired plished. Another the use of smooth upon becoming or bend over at the edge.
Fig. 3 shows a form of construction b in which only the edge of the disk is broadened, while inthe construction b shown in Figs. 4 and 5, the broadening of the edge bodied a disk havin a transversely flat cylindrical face and sharp cutting edges p jecting laterally therefrom. It will also be clear that the sharp edges, in the specific form shown, are contiguous with the flat cylindrical face and are on a line therewith.
I claim 1. A metal cutting disk comprising abody portion having a transversely continuously fiat cylindrical face and sharp cutting edges projecting laterally therefrom, substantially as described.
2. A metal cutting disk comprising a body portion having a transversely continuously flat cylindrical face and sharp cuttin irregular edges projecting laterally therefiom, substantially as described.
3. A metal cutting disk comprising a body substantially as described.
4. A metal cutting disk comprising a body portion having flat parallel sides and a transversely, continuously fiat cylind rical peripheral face, said disk having sharp cutting edges projecting laterally of the body portion and parallel with the axis of said disk and not extending radially outwardly from said cylindricaliface, substantially as described.
5. A metal cutting disk comprising a body portion having a peripheral face which is cylindrical and transversely fiat continu ously about the disk, said disk having sharp cutting edges projecting laterally of the body portion and parallel with the axis of the disk and not extending radially outwardly from said face, substantially as described.
In testimony whereof I in presence of two witnesses.
