An experimental urban car was designed and built by Western Washington State College as an entry in the international Urban Vehicle Design Competition. The car was designed with a novel form of mid-engine rear drive chassis. A novel (pyramid link) rear suspension solves many problems. Extreme Ackerman steering allows a 9 ft turning radius. New systems were developed for adjustable pedals, steering, and seat squab height. The chassis quick-disconnects into three major sections to facilitate servicing. A bias beam brake linkage allows easy adjustment of front-rear brake bias. The low emission engine runs on propane and is equipped with a thermal reactor and an EGR system. The body chassis center unit is made from epoxy fiberglass surface aluminum honeycomb. Passive restraint seat belts are attached to semigull wing doors. Five mph bumpers are fitted to each end. The front uses extrusion bolts and the spare tire; the rear uses beverage cans in compression. A headrest window provides

Brakes and Brake-Linings from a Service Viewpoint

290047

01/01/1929

A TABULAR statement in which comparisons are made between acceleration and deceleration is presented by the author as proof of the need of frequent and scientific maintenance practices with regard to brakes. From the viewpoint of service, the author believes that the engineer's findings as to what constitutes the best lining for the particular brake he has designed for his particular car must be adhered to strictly. No one brake-lining will work equally well on all cars. In reconditioning used cars of any make, he has purchased the lining supplied by the manufacturer of the particular make of car when possible. Although water affects brakes equipped with molded linings, the trouble is only momentary, according to the author, because the heat quickly dries off the surface moisture. Squeaks are seldom caused by the molded lining itself, but mostly by protruding rivets, out-of-round brake-bands or brake-shoes, foreign matter on the linings, or eccentric adjustments. In conclusion, and

Continuation of the 1922 Report on Brake-Lining Tests 1

270047

01/01/1927

A REPORT on the investigation of brake-lining materials by the Bureau of Standards was made by the author in 1922. The present paper gives information on work done in this field since that time. It places on record a summary and discussion of various test-methods and equipment at present employed by brake-lining manufacturers and others in the automotive industry. The difficulties connected with this work, resulting from the varying characteristics of brake-lining materials, are brought out. It is shown that some of the test methods in use do not furnish a basis for ready or fair comparison of different brake-linings. Other test procedures are so limited as to give only an incomplete picture of the characteristics of the brake-linings under conditions met in service; therefore, the test schedules generally require readjustment and amplification because a full and satisfactory knowledge of these materials can be obtained in this manner only. Finally, the essential features to be given
