. Electric railway gazette . covering a pulley in that way it is impossi-ble to keep the air from getting under andeventually breaking it out at the rivets. Besides,so many rivets being necessary to cover a pulleyprevents the proper adhesion of belt to pulleyand also cut out the belt. There can be nocement made that will perfectly fasten leather toan iron pulley ; for the expansion and contrac-tion of the iron will loosen it, and the covering isworse than useless without a perfect union withthe pulley. The Patent Pulley Covering here shown, beingwider than the pulley face, its edges are broughtover the edges of the rim and then turned towardseach other and fastened on to a malleable ironsegment clamps, with teeth to hold the leather;the clamps are placed around the pulley underthe rim, and drawn together by a quarter-inchbolt, which draws the leather tight over the faceand edges of the pulley. In this way, the leathercan be drawn on the face of the pulley as tightas a drum-head, as the process of drawing is in a. degree similar, and should the covering ever be-come loose, it can be tightened in a few minutes,simply with a screw-driver to turn the bolts. It is claimed by the patentee that the pulleybeing so perfectly covered, the belt will wearinuch longer ; that a leather covered pulley willdrive fifty per cent more than an iron faced pul-ley ; that belts can also be run slacker, thus pre-venting heated journals and wear on machinery. *Sprague Electric Equipment Co., Belting Co , St. Louis, Mo. 2o THE STREET RAILWAY GAZETTE.
