Safety protectors for motorcycle exhaust pipes
First Claim
1. What I claim as my invention is a modification of motorcycle exhaust pipes which will prevent the motorcyclist from burning his legs on the hot pipes, by placing an insulator between the exhaust pipe and an outside barrier to the leg, which barrier may be a rod, slat, or decorative chromed shield.

Abstract
Any existing material can be used as an insulator provided that it can withstand the heat of the exhaust pipe without melting and not transfer enough heat to the exterior barrier to cause a bare leg to be burned. The material must also be able to be cut or molded to a variety of shapes yet hold its finished shape. The material I used in my prototypes was high density polyethylene, commonly available at plastics suppliers, but other materials, such as bakelite, could be used. I used a one-half inch round aluminum rod as a barrier to the leg because a round rod was easier to shape to the line of the pipe, but a flat bar could be used. I retrofitted an existing, factory-installed chromed pipe shield to use as a barrier by installing the same insulating material between it and the exhaust pipe. No unusual or especially invented materials were used. My invention rests on the idea of an insulated barrier between the exhaust pipe and the leg, not on specific technical innovations of the materials to be used for that purpose.
