NEW BRAKE SHOE CUTS STOPPING TIME, REDUCES WEAR AND SPARKING

A new brake shoe completely interchangeable with the standard metal shoe promises better train control, increased life and almost total spark suppression. Key to the breakthrough is an alloy of iron which exhibits a vastly different metallurgical structure from that of a standard shoe. The Samson shoe reduced stopping distance 32 percent and confirmed the improvement in train handling. The Samson retained the favorable friction characteristics of the standard metal shoe at static breakaway and low speed. Comparative sparking under drag braking conditions tested with cheese cloth placed in the trajectory of sparks leaving the wheel. At 45 mph, sparks from the standard metal shoe ignited the cheesecloth in seven minutes; Samson caused no fire.
