Having described the details of constrnction of my improved grlndlng wheel, the
necessity for using a hollow shaft feed,
which isat EllltlYDGS objectionable and particularlyso in connection with grinding or ironing operations where the grinding mate rial, it raised above the shaft bearings, sooner or later works into the bearings with destructive effect.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but what I claim is 1. In a grinding machine, ashaft, a wheel head rigidly secured thereto, and a plurality of concentric grinding rings secured to said head and provided with upwardly and rearwardly inclined pockets across the inner facesof said rings. V 2. A grinding wheel having a plurality of separately formed, concentric grinding rings detachably secured to its lower face and each ring having a series of V-shaped upwardly and rearwardly inclined grooves formed across its inner face. 7 i
3. A grinding wheel having a hub p01 tion formed with an opening therethrough designed to receivea shaft, and having a plurality of helical, downwardly-converging feed passages communicating with said tapered end portion and a grinding wheel rigidly seated thereon, the hub portion of said wlieelhaving a plurality of helical feeding passages, the inner faces of which are closed by said shaft and said passages being inwardly and downwardly directed toward the center of said wheel.
A, grinding machine comprising a shaf t and a grinding wheelrigidly attacheditherc to, theshaft engaging portion of said wheel having feeding passages formed therein adjacent said shaft; grinding rings mounted on the lowerface of said wheel each, provided with upwardly and rearwardly inclined pockets onthe inner face thereof, and said feeding passages being in communication with said rings.
6. A grinding machine comprising a shaft and a grinding wheel rigidly attached thereto, the shaft engaging portion of said wheel having a plurality of helical feeding passages formed therein open at their inner sides and said passagesbeing separated by ribs in said portion providing a tapered seat for said shaft; grinding rings mounted on the lower face of saidwheel, each provided with upwardly and rearwardly inclined pockets on the inner face thereof, and said feeding passages being in communication with said rings. M
7. In a grinding n'iachineya shaft having atapered end portion, agrindingwheel having a hub, said hub having a plurality of helical feeding passages formed therein open at their inner sides, said passages being separated by ribs in said huh providing a tapered seat for said shaft, said ribs heingnarrowed down to thin edges at their upper ends.
In testimony whereof I have hereunto aflixedlnysignature. a
