WHEEL DRESSER Filed April 1930 Inventor: George F. Taylor Mai/2270M His Attorney.
Patented Apr. 18, 1933 UNITED STATES vrn'rau'r OFFICE GEORGE I. TAYIrOB, OI SCHENECIADY, NEW YORK, .ASSIGNOB '10 GENERAL ELEGTRIG A CORPORATION OF NEW YORK WHEEL DBHSER.
Application fled April 1, 2380. Serial No. 440,837.
The present invention relates to tools adapted to be employed in surfacing or dressing abrasive grinding wheels. The surfacesof such wheels, after usage, are usually very rough and enerally have alternate circum ferential ri ges and depressions which render it difficult to provide a suitable cutting ed e on tools with such wheels unless the roug ened surfaces are removed.
It is one of the ob'ects of the present invention to provide an improved wheel dresser and method for ,making the same. i
The novel features which I believe to be characteristic of the present invention are set forth with particularity in the appended claims. The invention itself however will best be understood from reference to the following specification when considered in connection with the accompanying drawin in which Fig. 1 is a perspective view of a w eel dresser embodyin the features of the present invention; Fig. 2 1s a perspective view of the surfacing wheels disclosed in Fig. 1; Fig. 3 is a perspective view partly in section of a modified form of surfacing wheel; while Fig. 4 is a perspective view disclosing the method of assembling a -modified form of surfacing wheel.
Referring to the drawing, I have indicated at 1 a wheel dresser provided with oppositely disposed bearings 2 and 3 in which a shaft 4: is rotatably mounted. A series of discs 5 are mounted loosely on shaft t as indicated in Fig. 2. Discs 5 are made oi steel or other suitable material and are provided on their peripheries with a series of spaced slots 7 within which are mounted cemented tungsten carbideinserts 8. The inserts 8 are ground so as to fit closely within slots 7 and then copper brazed thereto, providing the finished wheels disclosed in Figs. 1 and 2.
If desired. I may employ a wheel dresser,
composed of a plurality of wheels 9 of the character disclosed in Fig. 3. In this figure, the cemented carbide inserts consist of relatively short cylindrical pieces 10 which are copper brazed in holes or slots in the wheel 9. the cemented carbide extending in a radial wheel 9.
direction well beyond the periphery of the which substantially In Fig. 4, 1 have disclosed a further modification of my invention in which theouter I ends of the cylindrical cemented carbide particles 11 do not extend beyond the periphery of the wheel dresser. In this case, the wheel as v comprises a pair of outer discs 12 and 13 and an inner centrally-disposed-disc 14 provided with radial corrugations. Each of discs 12, 13 and 14 is provided with a central 0 ening 15 to accommodate shaft 4. I In menu acturno tions of the corrugated discand thereby provides a pair of opposite, substantially flat surfaces to which discs 12 and 13 are applied. we The assembled discs are then heated in a hydrogen atmosphere in a suitable brazing furnace and the, cemented tungsten carbide brazed to the central corrugated disc and to the outer discs 12 and 13. At the same time discs 12 and 13 are copper brazed to the central disc 14:.
The hard metal composition employed inv my improved wheel dresser is cemented tungsten carbide, such as disclosed in Schrtiter Patents #1,5'l9,615 and #1,721,d16. This material generally consists mainly of tungsten carbide or the like but may contain Bil .up to 20% of a hinder or cementing medium such as cobalt. The cemented carbide is very as hard and although somewhat brittle provides an efiicient and relatively inexpensive wheel dresser when mounted in the manner shown and described.
It is immaterial whether the pieces ofcemented tungsten carbide project be and the periphery of the wheeler not. ere the pieces do not roject beyond the periphery of the wheel, t e supporting portion of. the wheel at its periphery wears away rapidly so that the cemented tungsten carbide ieces thus roject beyond the rim of the whee What I claim as new and desire to secure by Letters Patent of the United States, is:
radially corrugated plate having a substantially smooth outer periphery, cemented carbide pieces mounted in the corrugations on both sides of said plate and at the outer edge thereof and rigidly secured thereto, the outer ends of said cemented carbide pieces being flush with the outer periphery of said cor:- rugated plates.
2. A wheel dresser com rising a circular, V radially corrugated plate aving a substantially smooth outer periphery, cemented cart bide pieces mounted in the corrugations on both sides of said plate and at the outer edge thereof and rigidly secured thereto, the outer ends of said-cemented carbide pieces being flush with the outer peripher of said corrugated plate, and retaining p ates secured to opposite sides of said corrugated plate.
In witness whereof, I have hereunto set my hand this 31st dav of March, 1930.
. GEORGE E. TAYLOR.
