Afterthe oil is taken from the barrel and is put into the tank it is undercomplete automatic control. Third Rail Insulator Frequent inquiries lor an insulator adapted for the third railsystem have resulted in the Ohio Brass Company, of Mansfield,Ohio, bringing out lor the market a device similar to the illus-tration shown herewith. This is of the same general character asmany of its predecessors, but presents several new features whichgive it originality; in fact, a patent has recently been allowed theOhio Brass Company upon it. This insulator consists of a malleable iron standard rigidlysecured to an insulating body of vitrified clay, or some similar. THIRD RAIL INSULATOR material, which is of the proper size and design to support thethird rail with safety, and also present sufficient surface leakage olthe current over its exterior. Upon this insulating body isfastened-a malleable iron cap casting which supports the thirdrail, and, by means of lugs on each side, holds it in alignmenthorizontally, but permits vertical play or motion to obviate thetrouble arising from the breaking of the insulators, which hasoccurred in the past, from the rail being secured too rigidly to theinsulator. ♦ ♦♦ Head-Lights for Electric Cars The Multiplex Electric Company has recently published a shortcatalogue descriptive of the various styles of corrugated reflectorsmanufactured by it for steam and electric railway cars. These re-flectors are spun out of a heavy gage of brass, and their form con-sists of a series of convex and concave shells, the size and radiusvarying with the style and kind of light to be used. Eac
