No. 20 HERO EMERY GRINDER
A practical tool grinder for carpenters, builders and all users of tools. The picture shows a chisel in position for grinding on the Universal sliding carriage. With this invention it is impossible to grind a tool imperfectly. A true square or any angle or bevel can be had instantly. Beside, with this method of grinding the tool is ground slightly concave, thereby dispensing with a great deal of running on the oilstone, which is a great saving of time as well as oilstones. For grinding cold chisels, punches and general work the Universal carriage is removed and the ordinary rest used. The machine is well made of best materials procurable. The spindle is 5/8 in. steel, with left hand thread for tightening the wheel between collars. A 6 x ¾ solid emery wheel is furnished. The frame is one solid casting, having holes for screws to secure to bench. Weight, complete for shipping, 18 pounds. The Hero No. 20 has been on the market for two years and is made by the Robertson Manufacturing Co., Buffalo, which has thousands of letters from users who speak in the highest terms, many stating the machine is worth fully double the price paid for it. In another column will be found this company's ad, with a special offer for a short time. This company is reliable and has built up a large trade on these machines.
