In principle thiswheel guard resembles the ordinary type, but its construc-tion is like that of a farmers hay rake. Although nowfirst offered for general use, the new scraper has alreadybeen tried out satisfactorily on the Kalamazoo city lines. The essential parts of this guard include a tripping fen-der which when engaged with an object breaks a triggerjoint, thereby allowing the guard to drop to the rails. Thisfender, however, is not affected by the vibration incidentalto ordinary car running. A pedal on the platform is usedto restore the wheel guard to its original position. Theguard basket will pick up an object from the track with-out the jarring which is unavoidable with a rigid basketbecause it is constructed of fourteen curved teeth madefrom ij^-in. x J^-i
