CLAMP FOR GRINDING WHEEL. MONARCH CLAMPS FOR GRINDING WHEELS. The emery and corundum wheels which are made by eitherthe vitrified process, semi-vitrified or silicate process, and theelastic process, by the Monarch Emery & Corundum Wheel Com-pany of Camden, N. J., are furnished in a great variety of shapesfor use with the different makes and classes of grinding ma-chines on the market. The two types of clamps illustrated weremade especially for use with certain lines of grinding machinesto replace the old method of cementing and yet not change theconstruction of the machine. They hold the wheels firmly andeliminate the annoyance caused by the loosening of wheels ce-mented on the spindle. The clamp shown in Fig. i is used with a 24 x 2J4 in. wheelfor the Sellers No. 1 tool grinder. The clamp consists of threeparts. That portion which is recessed to fit the end of thespindle is held securely in place by a nut. The grinding wheelis slipped over this portion of the clamp
