Belt Rait, Checking Machine—Bnb Vntw. Interesting information in a letter from a superintendent ofmotive power who is using spirally corrugated boiler tubesunder the very severe conditions imposed in connection withthe burning of lignite fuel in locomotives is presented in thefollowing quotations:. Machine. rail in place, having been sawed to length and gained for postsand braces. Belts for the angle knives, for the brace gains,run to the countershaft with a continuous pulley overhead ex-tending the full length of the machine, in order that anychange of angle, or shifting of the knives, may be accom-plished without removing the belts. This machine turnsout about 220 belt rails in ten hours. The other machine is a combination tenoning and checkingmachine for carlins. This machine is illustrated by a photo-graph only. It consists of an ordinary tenoning machine withthe additional shafts and knives shown in the photograph, driving pulley on the end of the cutter shaft is almost aball in form. In other words it is excessively crowned to ac-commodate widely different variations of angles to which theshaft may be set. This machine requires the carlins to beturned end for end. making two operations to finish thepiece. This might be
