A good strainer protects your equipment ana pipelines. Maintenance men said "give us a strainer with a blow-off cap that comes out easils and makes up tight; a screen that can be put back in place without a lot of Addliog around". The easy-io-remove Yorway cap meets these requirements, it has straight (not tapered) thread, machined face and spark-plug-type gasket. Permits easy removal for cleaning. Insures proper screen alignment when replaced in body. Screen itself is of high grade woven monel wire, or perforated if desired. Body of strainer is iron or steel, cad* mium-plated for protection against cor* rosion and for better appearance. Available in six sixes, Vi" to 2", for Eressures to 600 lbs. Reasonably priced. lundreds of thousands in use. Stocked and sold by ISO Mill Supply Houses. See your dealer or write for Bulletin S-201. YARNAU-WARING COMPANY 100 Mermaid Avo. Philadelphia 18, Po.

Table II U a typical selection nkfcl In some Instances alternate belt ^c'l lions- are listed, indicating that eUba makes a satisfactory drive. Bat one the other gives the most economical drive, and it is often necessary to ctl culate and price each drive, and coq. pare them before the proper choice it made. The table footnote is a guide to the belt section that results in the most economical drive for a particularapplication. Larger diameter abeam sometimes permit fewer belts on the drive. This not only reflects e saving <m both the original set and replacements,' but actually lowers initial cost of tbs complete drive. Part of tbe saving i effected* in the lower price of the sheaves. Because of machining costs it is almost always truo that sheaves of slightly larger diameter but with fever grooves for a given drive are town h price then sheaves of slightly smaller diameter but with more grooves. Multiple Bolts. If multiple belts lie used, o slight increase In diometer of sheaves is often enough to increase (he horsepower-transmitting capacity of tbo ' drive to the point where fewer belts'do a eatisfeciory fob. For instance, D sec-, tion belts on a 13.0-in. sheave driven by an 1150-rpm motor have a rating of 15.3 bp each. Used on e 14.0-m. sheave, they have a rating of 17.9 bp each, nr 2.6 hp more for each belt On the first drive eight belts hive s total rating of 122 hp, while on the sec ond drive only seven belts have a total of -125 hp. Second drive not only has s greoter total horsepower-transmitting capacity but is actually lower la price than the first. So it would be more economical as. well as a beuercngi* neered drive. Similarly, on certain drives, a fewer number of larger belts on Urgcr-diso* eter sheaves often have equal or greater horsepower-transmitting capac ity than a greater number of smaller bells on amaller-dkuneter sheavesWhere this is possible, the drive with the larger belt section Is often prefer able from an engineering standpoint, and almost always lower in first ***** It is this principle of selection ths* ^ used in the pro-engineered or preoO' lected drive sections in V-belt catalogs Slock drives for normal applications o all kinds ore wholly, or portly * e lated, and only those listed that *rfl from an engineering angle as *eu lowest )n first cost and roalntensn^ This assures the most economical lor an application without the 'f** ity of a customer having to it himself.
