Image Description:
The 8-inch electric bench grinder shown in the accompanying illustration, which is a recent product of the Black & Decker Mfg. Co., Towson Heights, Baltimore, Md., is driven by a ¾-horsepower motor of the universal type, similar to that supplied in portable electric drills manufactured by this company. The motor operates on either alternating or direct current. The grinding wheels are set well away from the motor casing and arranged to overhang the bench. This construction makes it possible to grind long pieces and odd shapes, and also enables the grinding wheels to be worn down to the clamping washers. The motor is air-cooled, the intake for the air being located 12 inches from the grinding wheels, a sufficient distance to eliminate the danger of grit being drawn into the machine. Grease is used as a lubricant throughout. This machine is supplied with one coarse and one fine grinding wheel, 8 inches in diameter and ¾ inch in width. Wheel guards, adjustable tool-rests, and an electric cable are also furnished as regular equipment.
