The arcs are operatedin multiple, hut a separate manage panel should be utilised foreach. The use of a separate control panel makes eachoperator completely independent of the other.

Kansas City,Mo., has recently placed on the market place an air strainer forlocomotive air compressors which is created of malleable ironwith either Ij-in. or 2-in. fittings, and weighs 82 lbs. ^ tf °Taa^^ Section of the Locomotive Air Pump Strainer This strainer could be applied to the intake of the air com-pressor in either the horizontal or vertical position. It con-sists of a six-in. by four-in. cylinder, filled with oil-soakedcurled hair, by means of which the air should pass just before it reaches

strainer Applied to the Air Pump the cylinder. This cleans the air of foreign matter just before itpasses to the compressor. The strainer is offered with ahood that overlaps the outer wall of the cylinder for a single inch. so that the air is drawn in from the below side of the hoodand not directly into the strainer. This construction pre-vents rain or snow from acquiring into the strainer and finallyworking into the cylinder. It also prevents the possibilityof squirting oil into the compressor, a practice that is be-coming too widespread with the enginemen. The curled hairbeing soaked with oil will stop the strainer from freezingin cold climate. HACK SAW MACHINE A new hack saw machine has Ijeen placed on the marketby the L. S. Starrett Business, Athol, >Iass., which includesa quantity of intriguing features. It is the initial machine tobe put on the industry b- this compan)-, and was developedbecause of its connection in the metal cutting industrieswhere its hack saw blades are utilized. There are fou

THE Cost OF COMPRESSED AIR Technique OF SECURING STEAM GAGES BY W. S. WHITFORDChicago & North Western, Milw The illustration shows a steam gage bracket to which has beenapplied a simple attachment for holding the gage in positionwithout the use of bolts or machine screws.

By disconnecting the union the gage may possibly be removed. BY THOMAS F. CRAWFORD Twenty years ago when pneumatic tools have been in their infancythe installation of an air compressor did not demand the care-ful study which is now essential, since the great savingin time effected by tlie substitution of air tools for hand toolsovershadowed all other costs.
